Title: Seat belt return spring force reducer - has two eccentric disc assemblies operating axially on faces of flange fitted to spring biassed bolt
Inventor: WOLFF HANS-DIETRICH
IPC: B60R22/44
Filed: 1976-09-29
Abstract: When the belt is pulled out prior to use, the eccentric disc assembly (3a) engages with the flange of bolt (4) to screw the bolt into nut (5). At a maximum peripheral distance of the cam surface the motion of the flange ceases and the flange becomes stationary. During the reclining movement of the user, the eccentric assemblies (3a, 3b) rotate in opposite directions, and the eccentric disc (3b) comes into locking engagement with the flange, causing the bolt (4) being screwed out. The eccentric disc assembly (3a) rests against the flange free of pressure from spring (8). The axial movement of the bolt (4) compresses spring (10), the energy required for this reducing the tensioning force of the rewinding spring.

Title: Vehicle engine fuel injection timing control - has blocking circuit to prevent fuel shut=off at low loads at high speed
Inventor: SCHNUERLE HANS
IPC: F02D41/14
Filed: 1977-06-14
Abstract: An oxygen analyser is the engine exhaust feeds a comparator whose output is fed to an integrating amplifier. THe output of the amplifier controls the duration of the fuel injection pulse. A flip flop circuit has a timing input from a circuit triggered by the injection pulses. The flip flop feeds a comparator which compares the duration of the flip flop output with the duration of the injection pulses. These are fed into its second input. When the pulse duration drops below a preset value, the comparator energises a switching circuit which blocks the integrating amplifier. This prevents fuel being shut off completely when there is no power demand on the engine at high vehicle speeds.
