I covered the plywood body mould with wet paper and laminated the surface with fiberglass, rubbed down the outside, removed the mould from inside, had it upholstered and added the leg. In the end I installed the red telephone on the inside wall of the chair. The naming part of the chair was easy, the BALL CHAIR was born. —
The Apollo Command Module reentered with the center of mass offset from the center line; this caused the capsule to assume an angled attitude through the air, providing a sideways lift to be used for directional control. Rotational thrusters were used to steer the capsule under either automatic or manual control by changing the lift vector.
On the Apollo 6 uncrewed Block I flight, the SM was painted white to match the command module's appearance. On Apollo 1, Apollo 4, and all the Block II spacecraft, the SM walls were left unpainted except for the EPS and ECS radiators, which were white. The EPS and ECS radiators were redesigned for Block II.
Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...
The aerospace part of the Ball Corporation was then known as Ball Brothers Research Corporation, and later won a contract to build some of NASA's first spacecraft, the Orbiting Solar Observatory satellites. The company has been responsible for numerous technological and scientific projects and continues to provide aerospace technology to NASA ...
The cable was connected to a cylindrical weight inside a tube. The weight rested on a lever controlled by a pneumatic solenoid valve. When the valve was actuated from the Launch Control Center (LCC), the pneumatic pressure of 600 psi (4,100 kPa) GN2 (nitrogen gas) rotated the lever down allowing the weight to drop down the tube.
The Red and Blue Chair is a chair designed in 1917 by Gerrit Rietveld. It represents one of the first explorations by the De Stijl art movement in three dimensions. It features several Rietveld joints. The original chair was constructed of unstained beech wood and was not painted red, blue, yellow, and black until around 1923.
Variants of the one-piece plastic chair designed by Canadian D.C. Simpson in 1946 went into production with Allibert Group and Grosfillex Group in the 1970s. [2] Other sources name the French engineer Henry Massonnet from Nurieux-Volognat with his "Fauteuil 300" from 1972 as the inventor of the monobloc. [3]
