Title: Hydraulic check valve with stepped valve chamber - operates without return spring and despite external vibration
Inventor: FASSBENDER ROLF
IPC: F16K15/04
Filed: 1977-06-24
Abstract: A check valve for hydraulic fluid has a steel sphere (5) which moves inside a valve chamber that has two different diameters (6, 7). The smaller diameter chamber (7) is next to the valve seat (4). It only allows a narrow radial gap between the sphere diameter (10) and the chamber wall (7). When a reverse flow of hydraulic fluid requires the valve to close, the fluid pressure moves the sphere against the valve seat. As the sphere enters the smaller valve chamber, only a minimal oil flow is required to close the valve and to keep it closed even if it is subjected to vibrations.

Patent DE-2731145-A1 (DE)
Title: High energy anti-rocket, anti-aircraft beam - obtd. from thermonuclear reaction by pumped laser in cryogenic low temp. chamber
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H01S3/09
Filed: 1977-07-09
Abstract: A weapons laser for antiaircraft and antirocket defence, operates by nuclear pumping with plasma components of a nuclear-thermonuclear reaction pellet. The laser beam strikes the pellet and generates plasma which expands to pass into the pump chamber. At the same time some plasma passes the supersonic head of the nozzle into the vacuum chamber of a vacuum pump with high redn. of pressure accompanied by expansion cooling. The vacuum in the pump chamber is 5-500 torr. The double-walled container surrounding the pump chamber, together with cavities in the head of the nozzle and its support arms, all contain circulating liquified gas, esp. a mixture of CO and N2. This gas escapes and vaporises through valves to constitute laser-active gas in the pump chamber. The gas forms a central axial laser gas column at low pressure between end reflectors, which is surrounded by the plasma flowing in at the head. Interchange takes place between the plasma vortex and the central laser gas column the pumping time of 5-10 milliseconds gives the central laser gas no opportunity to form temp. and/or pressure gradients, so that a laser beam is pumped along the gas column at 80-150 K and 10-250 torr pressure. At the partially transparent mirror at the end of the chamber, this beam is split, resulting in up to 30%, of the plasma energy being converted into light energy.
