Nurse Ratched is from Cuckoos Nest. This is a rather important component of a railroad car coupling mechanism.
A lot has changed since I built my first motorised narrow gauge train in 2014 but the basic concept remains the same. The locomotive holds a motor which drives its wheels and the wheels of the battery car via a set of universal joints.
This is the part of the MOC I get asked about most. So here it is, all secrets revealed for your interpretation. This is a scaled up version of the wing attachment mechanism I developed for Stephanie's X-Wing. This one had to be stronger to accommodate the heavier wings of this much larger BFF X-Wing.
ps. As a result of this change, I also have to make significant changes to the wing sections where they connect to the X-Wing body. This will in turn will require some redesign of the X-Wing body itself to accommodate this taller mechanism. This is part of the domino effect caused when making one change that ultimately requires another, that also requires another, etc... But it is better to fix this now, rather than trying to retrofit the final model. :P
The Tees Newport Bridge is a vertical-lift bridge spanning the River Tees a short distance upriver from Tees Transporter Bridge, linking Middlesbrough with the borough of Stockton-on-Tees, Northern England. It no longer lifts, but still acts as a road bridge in its permanently down position.
Designed by Mott, Hay and Anderson and built by local company Dorman Long, who have also been responsible for such structures as the Tyne Bridge and Sydney Harbour Bridge, it was the first large vertical-lift bridge in Britain.
Constructed around twin 55 m (180 ft) lifting towers, the 82 m (269 ft) bridge span, weighing 2,700 tonnes, could be lifted by the use of two 325 H.P. electric motors at 16 m (52 ft) per minute to a maximum height of 37 m (121 ft). In the event of motor failure a standby 450 H.P. petrol engine could be employed to move the bridge, but should both systems fail it was possible to raise or lower the span manually using a winch mechanism. It was estimated in 1963 by Mr R. Batty, long time Bridge Master at Newport Bridge, that "it would take 12 men eight hours" to complete the movement by hand.
The bridge was inaugurated by Prince Albert, Duke of York (later King George VI) and opened to traffic on 28 February 1934.
Originally, 12 men would have been employed to man the bridge around the clock, usually requiring four to drive it at any one time. This was accomplished from the oak-panelled winding house situated midway along the bridge span. During the 1940s and early 1950s this would occur up to twice a day with an average of 800 vessels per year passing under it, despite staffing difficulties during the 1940s when men were away fighting. However, as the number of ships needing to sail up to Stockton-on-Tees declined, so did the usage of the bridge.
The legal requirement to lift the bridge for shipping traffic was removed in 1989 after the repeal of a Parliamentary Act. Before mechanical decommissioning Mr Ian MacDonald, who worked on the bridge from 1966, finally as Bridge Master, supervised the final lift on 18 November 1990.
The Tees Newport Bridge still serves as a road bridge, carrying considerable traffic as a section of the A1032, despite the presence of the A19 Tees Viaduct a short distance upriver. In recent years it was repainted in its original green and some minor maintenance took place on the wire ropes and counterbalances which still take the majority of the bridge load. In 1988 the bridge was given Grade II Listed Building status.
In July 2014, work started to paint the bridge red and silver to mark its 80th anniversary. This was planned to take six weeks but was completed behind schedule and over budget mainly because of the poor condition of the steelwork, the result of lack of maintenance.
As ships dock on the banks of the River Tees up to the Tees Newport Bridge the Admiralty publishes tide times for the bridge location
Middlesbrough is a town in the Middlesbrough unitary authority borough of North Yorkshire, England. The town lies near the mouth of the River Tees and north of the North York Moors National Park. The built-up area had a population of 148,215 at the 2021 UK census. It is the largest town of the wider Teesside area, which had a population of 376,633 in 2011.
Until the early 1800s, the area was rural farmland in the historic county of Yorkshire. The town was a planned development which started in 1830, based around a new port with coal and later ironworks added. Steel production and ship building began in the late 1800s, remaining associated with the town until the post-industrial decline of the late twentieth century. Trade (notably through ports) and digital enterprise sectors contemporarily contribute to the local economy, Teesside University and Middlesbrough College to local education.
Middlesbrough was made a municipal borough in 1853. When elected county councils were created in 1889, Middlesbrough was considered large enough to provide its own county-level services and so it became a county borough, independent from North Riding County Council. The borough of Middlesbrough was abolished in 1968 when the area was absorbed into the larger County Borough of Teesside. Six years later in 1974 Middlesbrough was re-established as a borough within the new county of Cleveland. Cleveland was abolished in 1996, since when Middlesbrough has been a unitary authority within the ceremonial county of North Yorkshire.
Middlesbrough started as a Benedictine priory on the south bank of the River Tees, its name possibly derived from it being midway between the holy sites of Durham and Whitby. The earliest recorded form of Middlesbrough's name is "Mydilsburgh", containing the term burgh.
In 686, a monastic cell was consecrated by St. Cuthbert at the request of St. Hilda, Abbess of Whitby. The manor of Middlesburgh belonged to Whitby Abbey and Guisborough Priory.[1] Robert Bruce, Lord of Cleveland and Annandale, granted and confirmed, in 1119, the church of St. Hilda of Middleburg to Whitby. Up until its closure on the Dissolution of the Monasteries by Henry VIII in 1537, the church was maintained by 12 Benedictine monks, many of whom became vicars, or rectors, of various places in Cleveland.
After the Angles, the area became home to Viking settlers. Names of Viking origin (with the suffix by meaning village) are abundant in the area; for example, Ormesby, Stainsby and Tollesby were once separate villages that belonged to Vikings called Orm, Steinn and Toll that are now areas of Middlesbrough were recorded in the Domesday Book of 1086. Other names around Middlesbrough include the village of Maltby (of Malti) along with the towns of Ingleby Barwick (Anglo-place and barley-wick) and Thornaby (of Thormod).
Links persist in the area, often through school or road names, to now-outgrown or abandoned local settlements, such as the medieval settlement of Stainsby, deserted by 1757, which amounts to little more today than a series of grassy mounds near the A19 road.
In 1801, Middlesbrough was a small farm with a population of just 25; however, during the latter half of the 19th century, it experienced rapid growth. In 1828 the influential Quaker banker, coal mine owner and Stockton and Darlington Railway (S&DR) shareholder Joseph Pease sailed up the River Tees to find a suitable new site downriver of Stockton on which to place new coal staithes. As a result, in 1829 he and a group of Quaker businessmen bought the Middlesbrough farmstead and associated estate, some 527 acres (213 ha) of land, and established the Middlesbrough Estate Company.
Through the company, the investors set about a new coal port development (designed by John Harris) on the southern banks of the Tees. The first coal shipping staithes at the port (known as "Port Darlington") were constructed with a settlement to the east established on the site of Middlesbrough farm as labour for the port, taking on the farm's name as it developed into a village. The small farmstead became a village of streets such as North Street, South Street, West Street, East Street, Commercial Street, Stockton Street and Cleveland Street, laid out in a grid-iron pattern around a market square, with the first house being built on West Street in April 1830. New businesses bought premises and plots of land in the new town including: shippers, merchants, butchers, innkeepers, joiners, blacksmiths, tailors, builders and painters.
The first coal shipping staithes at the port (known as "Port Darlington") were constructed just to the west of the site earmarked for the location of Middlesbrough. The port was linked to the S&DR on 27 December 1830 via a branch that extended to an area just north of the current Middlesbrough railway station, helping secure the town's future.
The success of the port meant it soon became overwhelmed by the volume of imports and exports, and in 1839 work started on Middlesbrough Dock. Laid out by Sir William Cubitt, the whole infrastructure was built by resident civil engineer George Turnbull. After three years and an expenditure of £122,000 (equivalent to £9.65 million at 2011 prices), first water was let in on 19 March 1842, and the formal opening took place on 12 May 1842. On completion, the docks were bought by the S&DR.
Iron and steel have dominated the Tees area since 1841 when Henry Bolckow in partnership with John Vaughan, founded the Vulcan iron foundry and rolling mill. Vaughan, who had worked his way up through the Iron industry in South Wales, used his technical expertise to find a more abundant supply of Ironstone in the Eston Hills in 1850, and introduced the new "Bell Hopper" system of closed blast furnaces developed at the Ebbw Vale works. These factors made the works an unprecedented success with Teesside becoming known as the "Iron-smelting centre of the world" and Bolckow, Vaughan & Co., Ltd became the largest company in existence.
By 1851 Middlesbrough's population had grown from 40 people in 1829 to 7,600. Pig iron production rose tenfold between 1851 and 1856 and by the mid-1870s Middlesbrough was producing one third of the entire nations Pig Iron output. It was during this time Middlesbrough earned the nickname "Ironopolis".
On 21 January 1853, Middlesbrough received its Royal Charter of Incorporation, giving the town the right to have a mayor, aldermen and councillors. Henry Bolckow became mayor, in 1853.
A Welsh community was established in Middlesbrough sometime before the 1840s, with mining being the main form of employment. These migrants included figures who would become important leaders in the commercial, political and cultural life of the town:
John Vaughan established Teesside's first ironworks in 1841, The Vulcan Works at Middlesbrough. Vaughan had worked his way up through the industry at the Dowlais Ironworks in south Wales and encouraged hundreds of the skilled Welsh workers to follow him to Teesside.
Edward Williams (iron-master), although he was the grandson of the famous Welsh Bard Iolo Morganwg, Edward had started as a mere clerk at Dowlais. His move to the Tees saw him rise to ironmaster, alderman, magistrate and Mayor of Middlesbrough. Edward was also the father of Aneurin and Penry, who both became Liberal MPs for the area.
E.T. John arrived from Pontypridd as a junior clerk in Williams' office. John became the director of several industrial enterprises and a radical politician.
Windsor Richards, an Engineer and manager, oversaw the town's transition from iron to steel production.
Much like the contemporary Welsh migration to America, the Welsh of Middlesbrough came almost exclusively from the iron-smelting and coal districts of South Wales. By 1861 42% of the town's ironworkers identified as Welsh and one in twenty of the total population. Place names such as "Welch Cottages" and "Welch Place" appeared around the Vulcan works, and Middlesbrough became a centre for the Welsh communities at Witton Park, Spennymoor, Consett and Stockton on Tees (especially Portrack). David Williams also recorded that a number of the Welsh workers at the Hughesovka Ironworks in 1869 had migrated from Middlesbrough.
A Welsh Baptist chapel was active in the town as early as 1858, and St Hilda's Anglican church began providing services in the Welsh language. Churches and chapels were the centres of Welsh culture, supporting choirs, Sunday Schools, social societies, adult education, lectures and literary meetings. By the 1870s, many more Welsh chapels were built (one reputed to seat 500 people), and the first Eisteddfodau were held.
By the 1880s, a "Welsh cultural revival" was underway, with the Eisteddfodau attracting competitors and spectators from outside the Welsh communities. In 1890 the Middlesbrough Town Hall hosted the first Cleveland and Durham Eisteddfod, an event notable for its non-denominational inclusivity, with Irish Catholic choirs and the bishop of the newly created Roman Catholic Diocese of Middlesbrough as honoured guests.
In the early twentieth century this Eisteddfod had become the biggest annual event in the town and the largest annual Eisteddfod outside Wales. The Eisteddfod had a clear impact on the culture of the town, especially through its literary and music events, by 1911 the Eisteddfod had twenty-two classes of musical competition only two of which were for Welsh language content. By 1914, thirty choirs from across the area were competing in 284 entries. A choral tradition remained part of the town's culture long after the eisteddfod and chapels had gone. In 2012 an exhibition at the Dorman Museum marked the Apollo Male Voice Choir's 125 years as an active choir in the town.
Industrial Wales was noted for its "radical Liberal-Labour" politics, and the rhetoric of these politicians clearly won favour with the urban population of the North East. Penry Williams and Jonathan Samuel won the seats of Middlesbrough and Stockton-on-Tees for the Liberal Party and Penry's brother, Aneurin would also win the newly created Consett seat in 1918.
Sir Horace Davey stressed his Welsh lineage and stated that "it was scarcely an exaggeration to say that Welshmen had founded Middlesbrough", courting the Welsh vote that saw him elected MP for Stockton. However, others complained that local Conservative candidates were losing to "Fenians and Welshers" (Irish and Welsh people).
These sentiments had grown by 1900 when Samuel lost his seat after a Unionist complained publicly that the town had been "forced to submit to the indignity of being trailed ignominiously through the mire by Welsh constituents". Samuel lost the seat but regained it in 1910 with a campaign that made few, if any, references to his Welsh background.
From 1861 to 1871, the census of England & Wales showed that Middlesbrough consistently had the second highest percentage of Irish born people in England after Liverpool. The Irish population in 1861 accounted for 15.6% of the total population of Middlesbrough. In 1871 the amount had dropped to 9.2% yet this still placed Middlesbrough's Irish population second in England behind Liverpool. Due to the rapid development of the town and its industrialisation there was much need for people to work in the many blast furnaces and steel works along the banks of the Tees. This attracted many people from Ireland, who were in much need of work. As well as people from Ireland, the Scottish, Welsh and overseas inhabitants made up 16% of Middlesbrough's population in 1871. A second influx of Irish migration was observed in the early 1900s as Middlesbrough's steel industry boomed producing 1/3 of Britain's total steel output. This second influx lasted through to the 1950s after which Irish migration to Middlesbrough saw a drastic decline. Middlesbrough no longer has a strong Irish presence, with Irish born residents making up around 2% of the current population, however there is still a strong cultural and historical connection with Ireland mainly through the heritage and ancestry of many families within Middlesbrough.
The town's rapid expansion continued throughout the second half of the 19th century, fuelled by the iron and steel industry. In 1864 the North Riding Infirmary (an ear, nose and mouth hospital) opened in Newport Road; this was demolished in 2006.
On 15 August 1867, a Reform Bill was passed, making Middlesbrough a new parliamentary borough, Bolckow was elected member for Middlesbrough the following year. In 1875, Bolckow, Vaughan & Co opened the Cleveland Steelworks in Middlesbrough beginning the transition from Iron production to Steel and by the turn of the century. Henry Bolckow died in 1878 and left an endowment of £5,000 for the infirmary.
In the latter third of the 19th century, Old Middlesbrough was starting to decline and was overshadowed by developments built around the new town hall, south of the original town hall, the town's population reaching 90,000 by the dawn of the 20th century.[9] In 1900, Bolckow, Vaughan & Co had become the largest producer of steel in Great Britain and possibly came to be one of the major steel centres in the world.
In 1914, Dorman Long, another major steel producer from Middlesbrough, became the largest company in Britain. It employed a workforce of over 20,000 and by 1929 and gained enough to take over from Bolckow, Vaughan & Co's dominance and to acquire their assets. The steel components of the Sydney Harbour Bridge (1932) were engineered and fabricated by Dorman Long of Middlesbrough. The company was also responsible for the New Tyne Bridge in Newcastle.
Several large shipyards also lined the Tees, including the Sir Raylton Dixon & Company, Smith's Dock Company of South Bank and Furness Shipbuilding Company of Haverton Hill.
Middlesbrough was the first major British town and industrial target to be bombed during the Second World War. The Luftwaffe first attacked the town on 25 May 1940 when a lone bomber dropped 13 bombs between South Bank Road and the South Steel Plant. One of the bombs fell on the South Bank football ground making a large crater in the pitch. The bomber was forced to leave after RAF night fighters were scrambled to intercept. Two months after the first bombing Prime Minister Winston Churchill visited the town to meet the public and inspect coastal defences.
German bombers often flew over the Eston Hills while heading for targets further inland, such as Manchester. On 30 March 1941 a Junkers Ju 88 was shot down by two Spitfires of No. 41 Squadron, piloted by Tony Lovell and Archie Winskill, over Middlesbrough. The aircraft dived into the ground at Barnaby Moor, Eston; the engines and most of the airframe were entirely buried upon impact.
On 5 December 1941 a Spitfire of No. 122 Squadron, piloted by Sgt Hutton, crashed into rising ground near Mill Farm, Upsall, on the lower slopes of Eston Hills. Poor visibility due to bad weather and low cloud is believed to have been the cause of the crash.
On 15 January 1942, minutes after being hit by gunfire from a merchant ship anchored off Hartlepool, a Dornier Do 217 collided with the cable of a barrage balloon over the River Tees. The blazing bomber plummeted onto the railway sidings in South Bank leaving a crater twelve feet deep. In 1997 the remains of the Dornier were unearthed by a group of workers clearing land for redevelopment; the remains were put on display for a short while at Kirkleatham museum.
On 4 August 1942 a lone Dornier Do 217 picked its way through the barrage balloons and dropped a stick of bombs onto the railway station. One bomb caused serious damage to the Victorian glass and steel roof. A train in the station was also badly damaged although there were no passengers aboard. The station was put out action for two weeks.
The Green Howards was a British Army infantry regiment very strongly associated with Middlesbrough and the area south of the River Tees. Originally formed at Dunster Castle, Somerset in 1688 to serve King William of Orange, later King William III, this regiment became affiliated to the North Riding of Yorkshire in 1782. As Middlesbrough grew, its population of men came to be a group most targeted by the recruiters. The Green Howards were part of the King's Division. On 6 June 2006, this famous regiment was merged into the new Yorkshire Regiment and are now known as 2 Yorks, The 2nd Battalion The Yorkshire Regiment (Green Howards). There is also a Territorial Army (TA) company at Stockton Road in Middlesbrough, part of 4 Yorks which is wholly reserve.
Post Second World War to contemporary era
By the end of the war over 200 buildings had been destroyed within the Middlesbrough area. The borough lost 99 civilians as a result of enemy action.
Areas of early and mid-Victorian housing were demolished and much of central Middlesbrough was redeveloped. Heavy industry was relocated to areas of land better suited to the needs of modern technology. Middlesbrough itself began to take on a completely different look.
Middlesbrough's 1903 Gaumont cinema, originally an opera house until the 1930s, was demolished in 1971. The Cleveland Centre opened in the same year. In 1974, Middlesbrough and other areas around the Tees, became part of the county of Cleveland. This was to create a county within a single NUTS region of England, with the UK joining the European Union predecessor (European Communities) a year earlier.
Middlesbrough's Royal Exchange building was demolished, to make way for the road. A multi-storey the Star and Garter Hotel built in the 1890s near to the exchange on the site of a former Welsh Congregational Church, was also demolished. The Victorian era North Riding Infirmary was demolished in 2006 and replaced by a hotel and supermarket.
The Cleveland Centre opened in 1971, Hill Street shopping centre opened in 1981 and Captain Cook Square opened in 1999.
Middlesbrough F.C.'s modern Riverside Stadium opened on 26 August 1995 next to Middlesbrough Dock. The club moved from Ayresome Park their previous home in the town for 92 years.
With the abolition of Cleveland County in 1996, Middlesbrough again became part of North Yorkshire.
The original St.Hilda's area of Middlesbrough, after decades of decline and clearance, was given a new name of Middlehaven in 1986 on investment proposals to build on the land. Middlehaven has since had new buildings built there including Middlesbrough College and Middlesbrough FC's Riverside Stadium amongst others. Also situated at Middlehaven is the "Boho" zone, offering office space to the area's business and to attract new companies, and also "Bohouse", housing. Some of the street names from the original grid-iron street plan of the town still exist in the area today.
The expansion of Middlesbrough southwards, eastwards and westwards continued throughout the 20th century absorbing villages such as Linthorpe, Acklam, Ormesby, Marton and Nunthorpe[9] and continues to the present day.
This was a fun one - The idea was to build Narmoto with as many action features as I could reasonably fit on him. I'm particularly happy with the mechanism for retracting the shoulder launcher.
My new MOC is a dropship and it has a feature to drop a cargo pod. I've designed this mechanism in LDD but had to build it to make sure it actually works before I design everything else around it. There's four technic beams which move in and out on worm gears and a ton of little gears to join them all to the big knob on top. It's not quite as slick as I'd like, but it kinda works. Does anyone more technic minded have any ideas to make it run smoother?

Op vrijdag 1 juli voegde Stroom Den Haag een nieuwe sculptuur toe: Dutch Mechanisms van Folkert de Jong. Het beeld heeft als vertrekpunt de moord op de gebroeders De Witt in 1672. Die was het resultaat van de controverse over macht en leiderschap tussen de republikeinen en de Oranje royalisten, en markeerde het einde van de Republiek der Verenigde Nederlanden. Folkert de Jong legt met de verbeelding van deze zwarte bladzijde uit de geschiedenis ook een relatie met het heden: machtsstrijd en populisme zijn van alle tijden.
Het beeld staat momenteel op de hoek van de Lange Poten en het Spui, bijna voor de plenaire vergaderzaal van de Tweede Kamer, maar de beelden van het Sokkelplan (ik blijf het zo gewoon noemen) worden nogal eens verplaatst.
Tijdens de opnthullingsceremonie hield Bas Heijne een interessante toespraak.
いとこにグランドピアノの構造を見せてもらって感動…
弾いてもらってさらに感動…音楽っていいなぁ :)
I first saw the structure of a grand piano...
I was impressed...Love Music :)
Starting with Pullip Cheshire Cat, Pullips have a new feature that allows them to have partially open eyes instead of just opened or closed. I opened up Pullip Lupinus to rechip her and took pictures of the mech for anyone curious. The only difference appears to be the new blink levers.
MOC: Garage. A modern interpretation of the classic set 361 by the same name.
Two doors, like the original version - but two garage bays. I didn't want roller doors, because the old set has regular ones, so I fiddled around a bit with the folding mechanism, but it works perfectly now - there's a tiny gap between the doors and the frames when they are closed, but it needs to be like that for the doors to close at all.

Soil profile: A representative soil profile of Typic Xerorthents, tephra. (Soil Survey of Lassen Volcanic National Park, California; by Andrew E. Conlin, Natural Resources Conservation Service)
Landscape: Typic Xerorthents, tephra consist of very deep, excessively drained soils that formed in tephra from Cinder Cone. These soils are on tephra-covered moraines, outwash plains, lake terraces, and lava flows. Slopes range from 2 to 50 percent. (Photo: Lassen Peak and Chaos Crags are in the background and Cinder Cone is in the middle ground.)
Taxonomic Classification: Frigid Typic Xerorthents
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Tephra deposits are common in Lassen Volcanic National Park. Many soils have a few inches of tephra, and in some cases the whole soil profile to a depth of 60 inches formed in tephra. The more recent deposits show a distinct boundary at the buried soil profile, and the initial depositional beds are clearly visible.
Older tephra deposits have been mixed with the underlying soil profile by living organisms, such as ants and burrowing animals, and by tree throws and are not as obvious. Different volcanic vents have produced different characteristics, such as the mineralogy and size, thickness, and variability of the ejecta. The size, thickness, and variability within the deposit are also influenced by the proximity to the vent and the direction from the vent.
Major sources of recent tephra are Chaos Crags, Lassen Peak, and Cinder Cone. Tephra from Chaos Crags is pumicious and contains more volcanic glass than the basaltic andesite scoria from Cinder Cone. This difference in mineralogy can affect the rate of weathering. The weathering stage of a soil influences physical, chemical, and mineralogical characteristics that impact soil behavior. Soils that formed from some of the thicker deposits of tephra from Cinder Cone are Typic Xerorthents, Typic Xerorthents, tephra and Typic Xerorthents, welded.

Pitcher plant
Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar.
