Safer Weightlessness Simulator
System described in report simulates weightlessness of space for training of astronauts, without adverse effects of rapid decompression. As in previous simulators, trainee wearing space-suit performs training exercises while immersed in water. In new system, space-suit interior is not above atmospheric pressure. No need for trainee to undergo gradual decompression to prevent bends after lengthy exercise; nor is there need for medical team to be present.

Sealed Joints for Hard Suits or Robots
Shoulder-to-arm joint allows wearer to move with considerable freedom while sealing wearer from outside environment. Inner wall is set of bellows, compressed at inner arm and expanded at outer arm, but degree of compression or expansion changes continuously as arm moves. Joint also used on diving suits and on manipulation sleeves for autoclaves and high-vacuum boxes, and as protective cover for articulated torque drives in hostile environments.

Weightlessness simulation system and process
A weightlessness simulator has a chamber and a suit in the chamber. O-rings and valves hermetically seal the chamber. A vacuum pump connected to the chamber establishes a pressure in the chamber less than atmospheric pressure. A water supply tank and water supply line supply a body of water to the chamber as a result of partial vacuum created in the chamber. In use, an astronaut enters the pressure suit through a port, which remains open to ambient atmosphere, thus supplying air to the astronaut during use. The pressure less than atmospheric pressure in the chamber is chosen so that the pressure differential from the inside to the outside of the suit corresponds to the pressure differential with the suit in outer space.

Hard Suit With Adjustable Torso Length
Torso sizing rings allow single suit to fit variety of people. Sizing rings inserted between coupling rings of torso portion of hard suit. Number of rings chosen to fit torso length of suit to that of wearer. Rings mate with, and seal to, coupling rings and to each other. New adjustable-size concept with cost-saving feature applied to other suits not entirely constructed of "hard" materials, such as chemical defense suits and suits for industrial-hazard cleanup.
