Patent DE-2509033-A1 (DE)
Title: Safety valve for fluid drive - features two independently controllable control plungers with auxiliary plunger
Inventor: SCHMITZ BERNHARD
IPC: F15B20/00
Filed: 1975-03-01
Abstract: The safety valve is for controlling a hydraulic or pneumatic drive with electrically controlled plungers. Two independently controllable control plungers allow passage of the drive medium only in the operating position of both control plungers (1, 2). An auxiliary control plunger (4) has pressure acting on it only in the output position of the main control plungers. This auxiliary control plunger (4) has a contact (18) which initiates a start of the valve-controlled drive only when the auxiliary control plunger is under pressure. A further contact (19) initiates a return of the valve-controlled drive only when the auxiliary control plunger is under pressure.

Title: Silencer for pulsating gas flow noise - cheap, light, compact; for IC engines, and pressure reducing valves, has spring loaded plate stack
IPC: F01N1/16
Filed: 1975-04-04
Abstract: Silencing is effected by smoothing the gas flow, by forcing the gas through a long, very narrow slot formed e.g. by the gas between adjacent coils of a helix of circular section wire (8) fixed to a circular plate (15) with at least one balance hole (16) so that gas pressure, acting on the plate against a spring (17) held by a screwed plug (13) adjustable (14) in the spring guide sleeve (11), controls the gap width. The sleeve (11) supports the end plate (10) of an open cage (4) holding the wire helix flange (5) at the end of the expansion chamber, which also houses a flow restriction plate (18). Stacks of suitably shaped hollow discs can replace the wire helixthe restriction plate (18).

Title: Vapour density measurement in sulphur hexa:fluoride-filled switches - having piston balanced against spring to measure pressure changes with liq. expansion detector to compensate for temp. changes
Inventor: LINDER WILFRIED ING GRAD
IPC: G01L9/00
Filed: 1977-11-16
Abstract: The density of a gas inside a closed container uses a pressure sensor with temp. compensation. This consists of a cylinder with a spring-loaded piston, the top of which is subjected to the pressure in the vessel. Changes in pressure cause movement of the piston. This is registered by a glass cylinder contg. a coloured liq., such as alcohol, ether or mercury. The characteristics of the liquid are chosen so that temp. changes cause to change in the liq. level even though the piston moves. Used for monitoring the SF6 content of sealed electrical switches insulated with SF6 and detecting losses. The temp. compensation means that losses are monitored under all temp. conditions. The compensation is cheap to construct.
