Title: Individual spool winding for transformers and chokes - uses guiding and tension rollers with cheeks for offsetting conductor
Inventor: PFEIFER RICHARD DR ING
IPC: H01F27/28
Filed: 1979-07-19
Abstract: The winding conductor (1) is fed from a main supply coil and passes over a guiding roller, then through a pair of rollers (13) and is finally wound on a core (14). The roller train or the core (14) can be moved to and fro until the core has the required number of turns. The desired tension in the winding can be obtained by braking the roller pair (13), and for carrying out the offset in the conductor (1) the offset cheeks (10 and 11) are attached to the guiding roller, and these move together with this roller, so that the offset function is not interrupted during winding operations. This method of winding enables the available space on the winding core to be more efficiently used, by offsetting the conductor in a Z-shaped manner.

Title: Automatic transmission control for motor vehicle - prevents creep and permits drive disconnection when engine power is off
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/02
Filed: 1980-05-21
Abstract: The proposed controller is intended to prevent creep when the vehicle is stationary with the engine idling and 'drive' selected, and also to disconnect the engine at speed when there is no power output from it. The required effect is achieved by opening the hydraulic circuit controlling the clutch to the forward gears to atmosphere when the stipulated conditions are detected. The clutch actuator (1) is connected by a hydraulic line (4,6) to the manual selector switch. In this line is a control valve (5) which is operated by a solenoid (15) and a return spring (13). When the idle condition exists it is detected by an electronic controller, for example by sensing accelerator position, engine speed and road speed. The solenoid is energised moving the valve piston (7) to a position in which the hydraulic line (4) to the actuator is opened to atmosphere (17). When the accelerator is depressed, and other conditions are correct as sensed by the electronic controller, the solenoid is de-energised. Pressure in the incoming line (6) and the spring (13) move the piston (7) into the opposite position to connect the actuator with the full hydraulic pressure again.
