Title: IC engine crankcase oil level automatic monitor - using inlet vacuum aspirated throttle tube to control warning light switch
Inventor: RINCK HANS-JOACHIM DIPL ING
IPC: F01M11/12
Filed: 1976-05-20
Abstract: The automatic IC engine oil level monitoring device replaces the oil dipstick by a 1-2.5 mm bore throttle tube (1) with its inlet end located adjustably, by means of a clamping sleeve (5) -between the max. and min. design oil level. This tube is connected to one end of a cylinder (9) whose other end (11) is connected to the inlet manifold. At start-up inlet vacuum acts on an O-ring (7) sealed piston (8); when it overcomes the pressure of a spring (10) the piston rises and applies suction to the tube (1). If there is sufficient oil, this is drawn into the tube and piston movement is allowed down. Full travel, resulting in the closing of a circuit (16, 8, 11) activated by the ignition switch (14), is thus not achieved until after a Mono-flop switch (15) with a 3-5 second delay has opened again. A warning lamp (19) fed from the circuit thus does not light.

Title: Valve for crane hydraulic drive - has ball valve which closes when hydraulic supply fails to maintain upstream pressure (SW 22.8.77)
Inventor: FASTH INGVARD
IPC: F16K17/30
Filed: 1977-07-20
Abstract: The valve is used as a safety arrangement where e.g. cranes are operated hydraulically. The valve consists of a housing (1) in which a valve cylinder (9) is mounted. The valve cylinder is locked in position in the housing by means of a ball (13) which fits in an indent in the housing. The ball prevents the valve cylinder being moved by a spring. The ball is locked in position by a piston (20) which is kept inside the hollow valve cylinder by the pressure of hydraulic fluid. The piston acts against the force of a spring. When the pressure of the fluid in the valve chamber drops, the piston is pushed out of the valve by the spring. The ball is then free to drop out of the indentation, and the valve cylinder is pushed into the closed position by the spring.
Patent DE-2737714-A1 (DE)
Title: HF phase shifter for phase controlled antennae - has active semiconductor amplifier system enabling larger angle of phase shift due to negative resistance
Inventor: REITZIG RAFAEL DIPL ING DR
IPC: H01Q3/36
Filed: 1977-08-22
Abstract: The high frequency phase shifter has an active semi-conductor amplifier system, such as a field-effect transistor, or an IMPATT diode, whose negative resistance has a greater reactance component. This enables a change of the amplified output signal phase within a greater angle by the control of the operating point. If the system uses a field-effect transistor, the operational point control is attained by different adjustment of its gate voltage. The phase shifter may be used in a module integrated with the associated radiators. The system reduces the antenna losses, particularly when the negative resistance is optimised to obtain the greatest possible angular region.
Patent DE-2737833-A1 (DE)
Title: Pneumatic or hydraulic gear type motor - introduces fluid under pressure into root space between teeth of meshing wheels to give high efficiency
Inventor: BREUHAMMER HORST
IPC: F01C1/18
Filed: 1977-08-23
Abstract: The motor has a cylinder containing two meshing gear wheels. A fluid under pressure is introduced axially into a central bore in both wheels. The fluid flows out radially through passages which open in the root spaces of the teeth. Its pressure forces the teeth on the two wheels apart and so causes the wheels to rotate producing a useful rotary output. The efficiency is increased because the fluid pressure is exerted over the whole flank of each tooth and there is no unused part of the fluid or teeth.
