Title: Fuel injection timing system - converts dribble volume displacement into electrical signal for use with stroboscope lamp
Inventor: SEILER GUENTER
IPC: F02M65/00
Filed: 1975-06-07
Abstract: The injector dribble pipe is connected to a housing containing a spring loaded plunger which lifts against the spring pressure as soon as the injector needle begins to rise and displace the fuel in the dribble collection chamber. The plunger movement causes a pin to enter an inductive cell to produce an electric signal which is amplified and fed to a stroboscope lamp. The light from the lamp is directed on to a marked disc rotating at engine speed and the injection start is made visual in the usual way. The plunger is provided with an axial bore (31) and a restrictor (32) to permit the fuel to flow back to the tank.

Title: Standby hydraulic brake cylinder - has compressed coil spring released manually to provide braking if power supply fails
Inventor: TRZEWIK HERBERT
IPC: B60T17/08
Filed: 1975-09-22
Abstract: The standy-by brake cylinder includes a compressed coil spring to provide mechanical braking power in cases where the hydraulic system fails. The spring is compressed by an air operated piston and then retained by a cross pin. The hollow piston rod locates a forked spindle with which the cross pin can be manually twisted in order to release the spring pressure. Longitudinal slots in piston rod tube and piston sleeve enable the external pressure head to outstroke once the cross pin has unlocked the two piston tubes. This produces the required thrust on the hydraulic brake cylinders.

Title: Headlight warning buzzer for car - has decoupling diodes for operation if drivers door opened with lights on and ignition off
Inventor: NETH WOLFRAM DR RER NAT
IPC: B60Q9/00
Filed: 1975-10-14
Abstract: The warning buzzer (1) is linked to the power side of the supply via the light switch (7) and via decoupling diodes (3). If the driver's door is opened, then that courtesy switch (5) links the buzzer to earth, to warn the driver to switch off the lights. The driver's courtesy switch only operates the buzzer, and is separated from the other courtesy switches (11) by other diodes (6). If the ignition is switched on then the earth side of the buzzer is switched to the live side of the supply by a third diode (8) and ignition switch (9). A resistor (4) limits the amount of supply-earth drain in this case. The warning buzzer thus only operates with the headlights on and ignition off, and with the driver's door opened.
