Title: HV gas blast arc-extinguishing power switch - has spring-biased sliding screen in control of gas flow through turbulence grid into arc chamber
Inventor: KOPPLIN HORST DR ING
IPC: H01H33/70
Filed: 1990-07-20
Abstract: Two contact pieces (2, 3) sepd. by a fixed distance are surrounded by a concentric mechanical compressor comprising a stationary piston (5) in a cyliner (4) which moves with a third contact (7) to compress the arc-quenching gas in a space (6) around a turbulence grid (9) opening (10) into the arc chamber (11). A hollow cylindrical screen (12) displaced axially against a recoil spring (13) around the moving contact (7) controls the flow of gas through the grid (9) for the duration of the blast. ADVANTAGE - Arc-quenching capacity can be maintained with lower consumption of gas flowing at max. speed.
Patent DE-4024629-A1 (DE)
Title: Achieving passive gain for radar of similar - using plastics material or ceramics with or without pigments for antenna, waveguide or circuit
Inventor: STOLZENBERG PETER GEORG
IPC: H01Q19/06
Filed: 1990-07-26
Abstract: For use in h/f civil or military applications, for information or detection, a passive gain is obtd. by the use of plastics and pigments or sintered pellets with special chemical colourings or by plastics and pigments alone. By the use of such materials a.h.f. field acquires a so called bundling effect, resembling a horn antenna at the focal point of a parabolic mirror. Ceramic discs or sheets are also alternatives to plastics etc. The gain effect of plastics can be increased almost as much by pigmenting. Use as antennae has almost the same effect as a lens has on light. The "bundling" must arise, however, between antennae and parabolic mirrors or between antenna and target. The gain is limited in the end by the mechanical number by wave lengths in front of the antenna or in the waveguide. As the material is non-metallic it has no lightning protector. ADVANTAGE - Gain far exceeds that obtd. with semiconductors or valves. The "bundled" gain is noise-free. Lens effect is obtd.. Gain can be achieved between two microwave circuits in coupling/mixing area. The efficiency of all types of parabolae can be raised to new degree. In e.g. satellites, wt. is minimised and hence also size and wind loadings. Complete military range of radar absorption can be made ineffective.
