Title: Compact membrane pressure reducer - easily accessible and fitted by use of a bayonet type connection
Inventor: GRUBER WALTER
IPC: G05D16/06
Filed: 1973-06-16
Abstract: Membrane pressure reducer not requiring additional space for the cut-off between the connection piece and valve housing but can be exactly assembled despite its concealed arrangement and can be mounted or dismounted in the valve housing in the same direction. The upper part of the valve accepting the regulating spring is removably connected by screws to the annular body while clamping the membrane. The valve upper part is connected bayonet-type by a flange part to the valve housing and forms in the housing with a cylindrical bush extension a rotational swivel damper limited between an open and shut position of the feed inlet. The annular body accepts a latern-like recessed cylindrical hollow body, which seals off both sides of the feed inlet and limits the bulging of the membrane into the inlet. The body is provided with the valve seat on the end protruding into the rear pressure space through which the valve spindle passes, which is firmly clamped to the membrane by a shut-off body opening out into the rear pressure space and seals the front pressure space against the control space in front of the membrane. The control space is in pressure equilibrium with the rear pressure space by a longitudinal hole in the valve spindle. A sliding bush stationary to the valve housing and made of a friction-less material, e.g. a polyamide, is pref. arranged between the swivel slide and the valve housing, which bush accepts a sealing ring, a guide ring clamped to it arranged in the window passage of its wall as a seal for the swivel slide.

Title: Vehicle anti-blocking brakes - using radar system to determine accurate speed compared with speedometer giving wheel slip
Inventor: MUELLER KARL HEINZ
IPC: B60T8/171
Filed: 1973-05-14
Abstract: The vehicle is fitted with an on board radar system, directed onto the road/track to accurately measure the vehicle speed. The radar signal is compared with a speedometer reading to generate wheel slip signals, whose magnitude controls the brake modulating circuit.

Patent DE-2407235-A1 (DE)
Title: Carburettor with pressure loss compensator - prevents super-saturation of air with fuel by sucking in additional air
Inventor: EXINGER ERICH
IPC: F02M23/04
Filed: 1974-02-15
Abstract: The carburettor duct has a fuel jet, a butterfly valve and an auxiliary air supply pipe. As air passes through the duct its velocity increasee as its pressure falls and fuel is sucked into the air stream through the fuel jet. The invention claims that as the velocity increases the pressure loss affects only the fuel, increasing its velocity and so affecting fuel consumption because the air fuel mixture becomes supersaturated. To overcome this effect an auxiliary air pipe is fitted to the carburettor duct with the end of the pipe facing upstream. The lower pressure in the duct sucks in additional air against the flow of the duct air system.

Title: Cover for energy absorbing bumper - with plastic flaps to protect sliders and displaced when bumper compressed
Inventor: SROCK RAINER
IPC: B60R19/26
Filed: 1974-02-23
Abstract: The car bumper has a rigid section mounted on energy absorbing arms with the front of the bumper covered by a plastic strip. The plastic strip has upper and lower sections which cover the gap between the body and the bumper bar to form a streamlined shape, while protecting the bumper sliding mechanism from dirt. The upper and lower sections are provided with grooves on the outside, with the grooves running horizontally, while the leading edges of the sections rest on deflection flanges on the body. When the bumper is compressed the sections ride over the flanges, and when the bumper returns to its normal setting the sections slide back and cover the gap again.

Title: Fixing arrangement for electro-photographic copier - has suction rollers with progressively reduced speed to give better contact with heating plates
Inventor: KRUEGER WILM
IPC: G03G15/20
Filed: 1974-05-24
Abstract: The fixing arrangement is for an electro photographic copyer. Along the outside of a curved transport way for a copy carrier (6), are heated plates, with suction rollers (7), for the transport of the carrier (6). The speed of rotation of the suction rollers (7) is reduced from roller to roller in the direction of copy carrier travel. A cover plate prevents heat getting into the apparatus. The carrier is fed in and discharged by guide plates (9). Surfaces are guides for the carrier move to the adjacent surfaces. The progressive reduction of roller speed gives the copy carrier a larger curve and better contact with the heating plates.
