Title: Remote controlled stepping switch for models - has position set remotely to allow many control operations
Inventor: RABE ERICH
IPC: H01H9/16
Filed: 1975-06-21
Abstract: A remote-controlled stepping switch, for setting in motion any one of several operations via its many contacts, is for use in model aircraft/boat controls. Such control operations might be: rudder, speed, warning siren etc. The stepping switch contact slider is operated by an electronic servo circuit. This servo circuit moves the contact slider proportionally to the deflection of the control generator at the remote transmitter. The advantage lies in allowing an arbitrary number of control operations to be performed simply by selecting the position of the models stepping switch using remote setting circuitry at the transmitter.

Title: Adjustment device for contact springs - causes free sprint end to be deflected beyond elasticity limit for given spring cross section
Inventor: HAHN HELMUTH
IPC: H01H11/04
Filed: 1975-11-06
Abstract: A contact spring pretensioned more than the design limit is deflected by a controlled feeler of a pickup against its pretensioning. Its movement is continuously monitored by measurement of force and travel, and the spring characteristic is recorded and compared with the required characteristic. When the same value is reached in both characteristics, pickup movement is stopped. The pickup is in the form of a rectangular moving coil in an air-gap between a cylindrical permanent magnet and a soft magnetic circuit. An arc of circle with a small radius test sensor acts on the free end of a contact spring clamped near the system axis. Rotary movement is evaluated by a device generating analogue or digital signals converted into electrically evaluated signals.

Title: Fail safe brake system for presses - has double brake with both brakes operating alternately
Inventor: SCHNEIDER FRANZ
IPC: B30B15/14
Filed: 1976-03-03
Abstract: In a press a double brake arrangement is usually installed for safety reasons. Both brakes (7, 8) are independently operated against the force of springs. Both brakes are dimensioned so that each brake is capable of stopping the press in case one of the brake operating mechanisms fail. One of the brakes is used to stop the press, while the other brake is operated at the point where the press is stopped. To ensure that the brakes wear evenly, the brakes are used alternately at the two positions. The operating units (23, 24) for the brakes incorporate a bistable switch (27) which is switched over after the end of each press stroke.
Patent DE-2609445-A1 (DE)
Inventor: KATZER ERNST
IPC: B61H5/00
Filed: 1976-03-06
Abstract: Brake shoes (38) engage on the brake discs (22, 22'), which brake shoes (38) can be actuated via brake calliper levers (24, 26, 28, 30) on the one hand by a compression medium motor (32) and on the other hand manually by means of a handwheel (1) with a spindle (2), via a connecting rod (6) which is provided with a spring-energy store (8) and via a hand brake linkage (18). An intermediate lever (42) which is mounted on a support point (44) fixed to the underframe has on the one hand a first coupling point (41), which is pivotable to a limited degree by a fixed counterbearing (43) in the lifting-off direction, for the free end of the brake calliper lever (24). The intermediate lever (42) also has a second coupling point (47) for the hand brake linkage (18). For parking braking, the spring-energy store (8) is pretensioned to a specific value below the maximum force which can be exerted by the hand brake linkage. As a result, it is ensured above all that release processes of one of the two brake actuation means remain without effects on the released or unreleased state of the other brake actuation means. <IMAGE>
