"The purpose of hip replacement surgery is to remove the two damaged and worn parts of the hip joint – the hip socket, acetabulum, and the ball, femoral head – and replace them with smooth, artificial implants called prostheses, which will help make the hip strong, stable and flexible again".
NON-NUCLEAR COMPONENT STORES BUILDING 60 –
The function of the non-nuclear component stores was to hold the high explosive part of the bomb and its outer casing. The casing could probably be split into two units, the tail and forward part containing the high explosive and electronics. The bombs, minus their fissile components, were housed in three almost identical stores buildings 59-61, known as Storage Building Type 'D-D'. These are arranged in an arrowhead pattern, and are accessed from the internal loop road, and are all surrounded by 14ft 6in high earth traverses, revetted by a reinforced concrete retaining wall against the roadway.
The western store, building 59 was gutted by a fire during the 1980's and has subsequently been demolished. Its floor plan remains visible on the remaining concrete floor slab. The two remaining stores, buildings 60 and 61 are rectangular in plan, and are constructed from reinforced concrete columns and beams. Internally there are two rows of columns, 13in², which support the roof beams, 2ft by 9in, which carry the 9in thick reinforced concrete roof slab which is covered with bituminous felt. The rainwater gutters and down pipes are cast asbestos.
The wall sections are filled with 18in by 9in by 9in precast concrete blocks, internally the main storage area measures 190ft 2½in by 60ft. It is divided longitudinally into eleven 17ft by 3ft bays and cross ways into three bays the outer bays measure 17ft 6in and the central bay is 25ft wide. The maximum clear internal height was 12ft from the floor to the underside of the roof beams. The floor is surfaced with a hard gritless asphalt with the patent name 'Ironite'. The walls are painted pale green colour and the ceiling cream. in store building 61 the bay letters 0, N, M, and L are visible on the rear columns on the eastern side, suggesting the store was divided into 22 bays along the outer walls.
Abutting on to the front of the stores, and flanking the entrances, are plant and switch rooms, which originally contained heating and air conditioning plant to maintain a stable environment within the stores. A raised air extract duct is placed asymmetrically on the roofs of the stores. Entry into the stores is through a 10ft wide door opening with 12ft high doors. In the rear wall of the stores is a single door width, outward opening emergency exit. The first nuclear weapon the store was designed to hold was relatively large, a ''Blue Danube'' bomb measured 24ft in length and weighed 10,000lbs.
The problems of handling such large objects are reflected in the provision of substantial lifting gantries at the entrance to each store. Two variants are found, the simplest, exemplified by the middle store building 60 comprises a straight gantry. Over the roadway the gantry is supported by four 24in by 18in reinforced concrete columns, which support two 51in by 24in reinforced concrete beams. The upper beams of the gantry taper towards the entrance to the store where they are suppurted by two reinforced concrete columns. On the underside of the gantry is attached a 20in by 6½in rolled steel joist runway beam which runs to the entrance to the building. This was originally fitted with a 10 ton hoist. The gantry is covered by asbestos sheeting to provide a dry working area.
On the eastern and western stores the gantries were set at 30° to the front of the stores. In this variant an extra set of columns was placed at the 30° dogleg. Internally there is no evidence for a runway beam, so it presumed the bombs were lifted off a road transporter and loaded onto a bomb trolley for storage. It is not known how many bombs were kept in each store, or if the tail units were separated from the front part of the bomb for storage. Subsequent to the site being relinquished by the RAF a central corridor has been created in the stores by the insertion of breeze block walls. Doors in these walls give access to workshops along either side of the buildings. External windows have also been inserted in some of the bays.

Active components of the tireflies. The circular structure is a coil spring, which we are seeing end-on. When the structure is bumped, the spring bends until it hits one of the walls around it. When that happens, the circuit turns on and blinks for a little while. A neat trick is to instead force it to blink all day long by making the spring touch the walls all the time.

The N-Chanel JFET transistor BF256A required for the Wien oscillator ("A" version mandatory because of the 3 to 7 mA Idss) was replaced here (and only seen in this picture) by 2N5485 (Idss of 4 to 10mA), but be advised that his pins are reversed (BF256 1-G, 2-S, 3-D and 2N5485 1-D, 2-S, 3-G)

While Magic 8-Ball did not exist in its current form until 1950, the functional component was invented by Albert C. Carter, who was inspired by a "spirit writing" device used by his mother, Mary, a Cincinnati clairvoyant. When store owner Max Levinson was approached by Carter about stocking the device, he called in his brother-in-law Abe Bookman, a graduate of Ohio Mechanics Institute. In 1944, Carter filed patent for his device, assigning it to Bookman, Levinson, and another partner in what came to be Alabe Crafts, Inc. (Albert & Abe) in 1946. Under the Alabe name, they marketed and sold the device as The Syco-Seer. Carter, who, according to Bookman, was an alcoholic, died sometime before the patent was granted in 1948. Bookman soon made improvements to the Syco-Seer and in 1948, it was encased in an iridescent crystal ball. Though unsuccessful, the revamped product caught the attention of Chicago's Brunswick Billiards. In 1950 they commissioned Alabe Crafts to make a version in the form of a
traditional black & white 8-ball.

According to Wikipedia
A Beyer-Garratt is a type of steam locomotive that is articulated in three parts. Its boiler is mounted on the centre frame, and two steam engines are mounted on separate frames, one on each end of the boiler. Articulation permits larger locomotives to negotiate curves and lighter rails that might restrict large rigid-framed locomotives.
