S-IC First Stage
The S-IC (pronounced “ess one see”) was the first stage of the American Saturn V rocket. The S-IC stage was built by the Boeing Company. Like the first stages of most rockets, most of its mass of more than 2,000 tons at launch was propellant, in this case RP-1 rocket fuel and liquid oxygen (LOX) oxidizer. It was 42 meters tall and 10 meters in diameter, and provided 33,000 kN of thrust to get the rocket through the first 61 kilometers of ascent. The stage had five F-1 engines in a quincunx arrangement. The center engine was fixed in position, while the four outer engines could be hydraulically gimballed to control the rocket.
The S-IC was built by the Boeing Company at the Michoud Assembly Facility, New Orleans, where the Space Shuttle External Tanks would later be built by Lockheed Martin. Most of its mass at launch was propellant, RP-1 fuel with liquid oxygen as the oxidizer. It was 138 feet (42 m) tall and 33 feet (10 m) in diameter, and provided over 7,600,000 pounds-force (34,000 kN) of thrust. The S-IC stage had a dry weight of about 289,000 pounds (131 metric tons) and fully fueled at launch had a total weight of 5,100,000 pounds (2,300 metric tons). It was powered by five Rocketdyne F-1 engines arrayed in a quincunx (five units, with four arranged in a square, and the fifth in the center) The center engine was held in a fixed position, while the four outer engines could be hydraulically turned (gimballed) to steer the rocket. In flight, the center engine was turned off about 26 seconds earlier than the outboard engines to limit acceleration. During launch, the S-IC fired its engines for 168 seconds (ignition occurred about 8.9 seconds before liftoff) and at engine cutoff, the vehicle was at an altitude of about 36 nautical miles (67 km), was downrange about 50 nautical miles (93 km), and was moving about 7,500 feet per second (2,300 m/s).

Manufacturing
The Boeing Co. was awarded the contract to manufacture the S-IC on December 15, 1961. By this time the general design of the stage had been decided on by the engineers at the Marshall Space Flight Center (MSFC). The main place of manufacture was the Michoud Assembly Facility, New Orleans. Wind tunnel testing took place in Seattle and the machining of the tools needed to build the stages at Wichita, Kansas.
MSFC built the first three test stages (S-IC-T, the S-IC-S, and the S-IC-F) and the first two flight models (S-IC-1 and -2). They were built using tools produced in Wichita.
It took roughly seven to nine months to build the tanks and 14 months to complete a stage. The first stage built by Boeing was S-IC-D, a test model.
Components
The largest and heaviest single component of the S-IC was the thrust structure, with a mass of 21 ton. It was designed to support the thrust of the five engines and redistribute it evenly across the base of the rocket. There were four anchors which held down the rocket as it built thrust. These were among the largest aluminum forgings produced in the U.S. at the time, 4.3 meters long and 816 kilograms in weight. The four stabilizing fins withstood a temperature of 1100 °C.
Above the thrust structure was the fuel tank, containing 770,000 liters of RP-1 fuel. The tank itself had a mass of 11 ton dry and could release 7300 liters per second. Nitrogen was bubbled through the tank before launch to keep the fuel mixed. During flight the fuel was pressurized using helium, that was stored in tanks in the liquid oxygen tank above.
Between the fuel and liquid oxygen tanks was the intertank.
The liquid oxygen tank held 1,305,000 liters of LOX. It raised special issues for the designer. The lines through which the LOX ran to the engine had to be straight and therefore had to pass through the fuel tank. This meant insulating these lines inside a tunnel to stop fuel freezing to the outside and also meant five extra holes in the top of the fuel tank.
Two solid motor retrorockets were located inside each of the four conical engine fairings. At separation of the S-IC from the flight vehicle, the eight retrorockets fired, blowing off removable sections of the fairings forward of the fins, and backing the S-IC away from the flight vehicle as the engines on the S-II stage were ignited.

Albion Motors of Scotstoun, Glasgow was a Scottish automobile manufacturer, later it concentrated on building commercial vehicles. Today the company is a subsidiary of American Axle & Manufacturing, and manufactures axles, driveline systems, chassis systems, crankshafts and chassis components. It is Scotland's best known name in the motor industry. Albions were renowned for their superior engineering and reliability; their slogan "Sure as the Sunrise" was known across the globe.
Bus production
The earliest buses were built on truck chassis with two being delivered to West Bromwich in 1914.
In 1923 the first dedicated bus chassis was announced derived from the one used on the 25 cwt truck but with better springing. Bodies seating from 12 to 23 passengers were available. A lower frame chassis, the Model 26, with 30/60hp engine and wheelbases from 135 inches to 192 inches joined the range in 1925. All the early vehicles had been normal control, with the engine in front of the driver but in 1927 the first forward control with the engine alongside the driver was announced as the Viking allowing 32 seats to be fitted. Diesel engines, initially from Gardner, were available from 1933. The first double deck design was the Venturer of 1932 with up to 51 seats. The CX version of the chassis was launched in 1937 and on these the engine and gearbox were mounted together rather than joined by a separate drive shaft. Albion's own range of diesel engines was also made available.
After World War 2 the range was progressively modernised and underfloor engined models were introduced with prototypes in 1951 and production models from 1955 with the Nimbus.
With the Leyland take over the range was cut back. The last Albion double decker was the 1961 Lowlander and that was marketed in England as a Leyland, and the last design of all was the Viking, re-using an old name.

After more than a decade of conducting operations overseas, the Army Reserve is bringing its unique capabilities home to benefit communities across America.
Localities across the nation are tapping into these skills through the DoD Innovative Readiness Training program. First authorized in 1993, IRT allows reserve component units to hone their wartime readiness through hands-on training while simultaneously providing quality services to communities throughout the U.S.
As the military’s premier force provider of organized capabilities, the Army Reserve is ideally suited to conduct these missions, said Col. Rhonda Smillie, the 88th Regional Support Command legislative liaison.
“The Army Reserve is composed almost entirely of combat support and combat service support units,” said Smillie. “Those same enabling capabilities used in operations overseas are exactly what many communities within our own country could greatly benefit from.”
Those activities include providing support such as medical and dental care, water purification, veterinary services and engineering projects.
The Army Reserve’s most recent mission took place on Fort Belknap, a geographically isolated Indian Reservation in north-central Montana. There, 33 Soldiers from subordinate units of the West Medical Area Readiness Support Group augmented the Indian Health Services Hospital.
Named Operation Walking Shield, the mission began July 21 and concluded Aug. 1. The Army Reserve staff consisted of eight different medical specialties to include lab technicians, dentists, physicians, critical care nurses, behavioral health specialists, optometry technicians and podiatrists.
The augmentation of these Army Reserve medical personnel greatly enhanced the Fort Belknap Hospital’s own medical staff of seven, enabling the clinic to nearly double the care it provides to the more than 5,000 members of the surrounding Tribes. By conclusion of the exercise, the Army Reserve Soldiers treated more than 900 patients.
Nona Longknife, credentialing coordinator for the Fort Belknap Hospital, said the addition of these medical practitioners enables the hospital staff to augment and enhance normal operations with much needed services. According to Longknife, the Army Reserve Soldiers bring specialized skills not available at the clinic. This affords some Tribal members their only opportunity to receive much needed expanded care.
“During this time of year we have more patients coming in for check-ups and physicals for stuff like sports, schools and Head Start,” said Longknife. “We also don’t have some medical specialists here like podiatrists, so many of our patients, especially our elderly, are able to get much needed care that would otherwise be unavailable.”
Capt. Mathew Plouffe, commander of the 4225th U.S. Army Hospital, said this was their third year conducting this mission and the benefits for everyone have been undeniable.
“Our Soldiers get real-world training,” said Plouffe. “Our EMTs are going on EMT runs, they’re driving the ambulance, they are picking up patients and bringing them back to the emergency room – our nurses are getting real world nursing experience, our podiatrist is treating feet – our dental techs are doing cleanings and assisting dentists who are treating real dental issues – our behavioral health specialists are working out in the field and in the clinic. This is real world training!”
In addition, Plouffe said being able to help an underserved community has been great for moral.
“Everybody is working as a team,” said Plouffe. “It certainly builds moral and cohesion being able to have an impact on a community. We are taking care of Americans. Missions like these are our only opportunity to really do that.”
Montana Senator John Walsh visited the training at Fort Belknap for himself on July 27.
According to Walsh, the unique skills the Army Reserve brings are invaluable in addressing serious community needs within our own country.
"Innovative Readiness Training missions are a win-win for the community and for the military,” said Walsh. “Operation Walking Shield at Fort Belknap is a great example of the program’s success because personnel are able to hone medical skills while helping a community in need of those services.”
Missions like these are also a great way to build relationships between communities and the Soldiers who want to make a difference, noted Walsh.
“Service members are especially important in helping communities because they are exceptionally motivated to make a difference,” said Walsh.
Smillie, who facilitated Walsh’s visit and invited all members of the Senate Committee on Indian Affairs, said it is vital that the public and elected officials understand how Army Reserve IRT missions can benefit our communities.
“The Army Reserve is all about specialized capabilities. In addition to doctors and medical professionals, we have engineers, attorneys, transportation specialists,” said Smillie. “All these skills that enable our forces can also easily be transferred to the civilian sector and benefit our communities.”
This may be best illustrated by the example of Pfc. Johnna Snell who has paired her military occupation with her civilian career while simultaneously bettering her own community.
A member of the Crow Nation of Montana, Snell is an automated logistical technician assigned to the 4225th U.S. Army Hospital. She used her military training to qualify for her current civilian position as a supply technician for the Crow Agency Indian Health Services Hospital.
Snell said the combination of her background, military occupation, civilian occupation and current mission have all complimented each other greatly.
“I am proud to be a part of a unit that can actually help a Native American community through this program,” said Snell. “I’m also proud that I can do this for the Native people and bring this knowledge to other reservations.”
Snell has participated in Operation Walking Shield for the past three years. This year Snell served as the mission’s cultural liaison, charged with coordinating between the Tribes and the unit. According to Snell, the need for assistance is vast and the people greatly appreciate it.
“There is a need here and they struggle to find the services,” said Snell. “Every year we come back and they are excited to see us. The most rewarding thing is helping people in need.”
The value added to the Fort Belknap community is considerable in many aspects, said Longknife.
“Everybody understands that we get cut back, so we try to use everything the best we can,” said Longknife. “The services they provide let us saves for other things and prevents us from having to send an elder 200 miles away for the right care. Elders can’t travel like that all the time - it’s too hard on them.
“80,000 dollars is what I would have to pay for just three doctors to work two weeks,” continued Longknife. “With 80,000 dollars we could send one of our elders to a really good heart doctor, or have a child’s cleft pallet fixed, or have a child’s teeth fixed.”
Beyond benefitting from services the Army Reserve provides, knowing that someone cares and will help them impacts the community deeply, said Longknife.
“Our people have great appreciation for what is done here,” said Longknife. “Appreciation that the Army Reserve thinks that much of our people to take that two weeks that they could spend anywhere in the United States to do their Reserve time, and they choose to come here – and it fills the hearts of the people to think and know that somebody does care.”

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.

I love the way the colors came out on this one. It's sort of like a cross between terra cotta and maybe southwestern, but with a healthy dose of vintage antique paint layers. I have this one listed, but I might have to rescue it and make something for myself out of it.

As part of the team building component of Term 1 Project Management, students are given a box of dollar store objects and a mission: keep a marble moving along a course for as long a time as possible, with it ending up falling into an egg cup. Armed with plastic necklaces, dominoes, bendy straws, a roll of toilet tissue and other priceless objects, teams compete to create the best design to meet the goal. Upon completion, the teams analyze their designs for strengths and weaknesses and process key team dynamic components — How were design decisions made? How were disagreements resolved? How was leadership determined? Did team members contribute equally to the vision and how did they each fare when it came to implementation?
