Patent DE-2402291-A1 (DE)
Title: Vehicle brake pressure limiter - has differential area plunger exerting max force to wheel cylinders upon circuit failure
Inventor: BURGDORF JOCHEN DIPL ING
IPC: B60T8/18
Filed: 1974-01-18
Abstract: The brake power controller is basically an axially movable differential piston whose smaller surface is connected to the master cylinder, and the larger surface supplying pressure to the wheel cylinders. On a dual circuit brake system the failure of one circuit should enable the system to convey the entire brake power to those wheels connected to the intact circuit. On previous systems the arrangement of the pressure limited did not make it possible to comply with this. In the case of the circuit running through the pressure limiter, the pressure would reach the brake cylinders, but if the circuit running through the differential piston fails the position of the pressure limited would not permit the pressure to reach the brake cylinders connected to that end of the piston. The present arrangement prevents the pressure limiter becoming effective in the case of failure.
Patent DE-2405066-A1 (DE)
Title: Integrated circuit with field-effect transistor - has limited region in epitaxial layer bounded by separation zones
Inventor: KAISER REINHOLD
IPC: H01L29/808
Filed: 1974-02-02
Abstract: An integrated circuit with a field-effect transistor has in the epitaxial n-type layer over a p-type substrate a limited region, produced by p-type separation zones. A p-type semiconductor zone is introduced in the limited region and receives n-type regions as gate zones. Theses gate zones are designed as stripes; the drain and source electrodes are produced by evaporation. This process does not require the epitaxial layer to have the extreme thinness needed for conventional methods. The incorporation of a field-effect transistor in an integrated circuit is greatly simplified.

Title: Differential-pressure alarm switch with operating piston - has piston kept in centre position by centring spring arrangement
Inventor: BELART JUNAN
IPC: B60T17/22
Filed: 1974-03-20
Abstract: The switching device has a switching pin which is held with initial tension by a spring radially on the operating piston and is braced in the normal position and up to a certain axial displacement of the piston on an area of the piston which is limited by inclines running outwards at an angle. The force of the centring spring arrangement is so small that the operating piston can be displaced against the force of the centring spring with even a small pressure difference. The force of the spring is so great that the operating piston can be displaced, along with the switching pin, because of the inclines only when the differential switching pressure is exceeded.
