Title: Automatic trim control for hydrofoil boat - has servo valve to monitor trim flap position and maintain hydraulic setting
Inventor: GOEBEL PETER
IPC: B63B1/22
Filed: 1975-02-25
Abstract: The trim flap of the hydrofoil boat is set to its initial setting by a single control on the dashboard, with a hydraulic servo cylinder linked to the pivoted flap. The two sides of the servo piston are connected in parallel to a control valve and from there to a hydraulic pump. A monitor is linked to the valve and controls the flow of hydraulic pressure to either side of the piston in response to deflections of the trim flap from the set angle.

Title: Type impact suppression unit for typewriter with single head - effects rapid transition from printing to non-printing function
Inventor: WOLF UDO DIPL ING
IPC: B41J7/94
Filed: 1975-04-14
Abstract: When a symbol is selected for typing, a mechanism in the keyboard selects the force of blow and transmits it to the striker which executes a corresponding swivelling motion. The striker hits either one of two catches whereby it is released from its locking position with its nose projections against the stop plate until the associated support catches strike against a bolt. By suitable design of the support catches it is possible to direct the signal (e.g. via a Bowden cable) to the locking catches whereby as a base position these maximum forces of impact which are mostly required can be selected.

Abstract: A hydraulically operated disc brake on a vehicle wheel has a dual hydraulic circuit to improve the safety aspect of the braking system. The brake disc assembly consists of two parallel brake rings, attached to the wheel rim so that they revolve together with the wheel. An annular cylinder assembly, carried by the support bracket is located between the brake rings so that the friction plates attached to it are next to the two brake rings. The piston has a symmetrical step so that each half has its own cylinder chamber. Each chamber is then pressurised by an independent hydraulic line to obtain a dual brake system.
