Title: Safety cut-out arrangement for motor vehicles - applicable for protection in impact or roll-over situations
Inventor: LEPPER WILHELM DR-ING
IPC: B60K28/14
Filed: 1973-07-10
Abstract: The comprehensive coverage of electrical, acid and combustible fuel dangers in any abnormal situation for the vehicle relies mainly on the operation of a pendulum type contact bridge. A signal current passing through this bridging device activates relays that shut off the main ignition circuit and bring extinguishing procedures into operation. Once contact is made, the pendulum is held against the circuit closing bell-housing by magnetic means. An alternative signal circuit is completed by means of a mechanical switch operated through an impact plunger, whereby the same protective measures are applied.

Title: Sealing arrangement for axially split cable jointing box - uses disc with circumferential groove to close ends
Inventor: BUDICH HANS-PETER
IPC: H02G15/08
Filed: 1973-08-29
Abstract: The application is typically to telephone cables using, plastic jointing boxes with sealed ends. The improvement here proposed employs a sealing disc of flexible synthetic material which is bored out to suit the cable size, and split radially so that it can, if necessary, be fitted onto an existing installation without a free cable end. The disc has a flange which engages with a corresponding slot in the inner sealing chamber enclosure, and, on an axial extension, a circumferential slot which lies opposite a corresponding groove in the cable box. A hole and passage connect the disc groove with the sealing chamber. When the latter is filled with compound and the havles pressed together the compound is forced through the hole and passage to join up with compound previously placed in the grooves to form a reliable seal.

Title: Automatic sender search for H.F. receiver - tuning range is automatically traversed upon starting signal
Inventor: MATULL JENS
IPC: H03J7/18
Filed: 1973-09-11
Abstract: The search is stopped when the reception field strength exceeds a threshold value. The threshold is automatically reduced in steps during the search process; it is reduced by one step when the search run reverses its direction, or when it reaches the tuning range end and abruptly returns to its other end; or the search run is automatically started when the field-strength falls below the lowest threshold. In actual practice it will often happen that the user of the program switched on by the start button and the delay stage will not be able to hear the discovered sender. Should the user use the start button again he will again be tuned to the same sender, but an additional button is provided for tuning to the next strongest station.

Title: Protective brush contact breaker - uses compression spring with movable insulation piece inside carbon brush drilling
Inventor: SCHAEFER GUENTER
IPC: H01R39/58
Filed: 1973-11-08
Abstract: When the carbon brush reaches its minimum useable length, the current between the brush and collector is interrupted by the contact breaker arrangement. This is achieved by a compression spring housed in the longitudinal drilling of the carbon brush, whose force is greater than the contact force of the carbon brush onto the collector. The compression spring rests with one end on the end plate while the other end moves the insulating piece relative to the carbon brush and by that separates the carbon brush from the collector. The compression spring insulating piece and end plate form a constructional unit. The compression spring surrounds a pin which is rigidly connected to the end plate and is also connected to the insulating piece.
Patent DE-2356305-A1 (DE)
Title: PXE-elements polarisation-depolarisation cct. - has diode and monoflop preventing depolarisation-voltage-creep at depolarisation switch-off
Inventor: HOEHNE HANS-DIETER
IPC: H03K17/76
Filed: 1973-11-10
Abstract: The polarisation and depolarisation circuit, for PXE elements, has control voltages applied over a diode matrix (preventing unwanted depolarisations caused by 'cross-talk' between storage electrodes), to the transistor switches coupled one to each of the PXE elements storage electrodes and to the common opposing electrode. A string of diodes bridged by a monoflop circuit is connected between the diode matrix's output and the base of the transistor that controls the common electrodes transistor switch. This diode/monoflop circuit prevents the depolarisation voltage from creeping when the depolarisation signal is switched off. (N.B., owing to hysteresis the depolarisation voltage has been found just after switch-off to rise above its value just before switch-off).
