Title: Seat belt retractor system - has retracting spring with one end connected to motor-driven tension adjusting mechanism
Inventor: SINNHUBER RUPRECHT ING GRAD
IPC: B60R22/44
Filed: 1977-09-22
Abstract: The retractor mechanism consists of a housing (2) a spool (3) and a spiral spring (6).

Title: Turbocharged engine intake pressure regulation system - has exhaust discharge valve opening at decreasing pressure with increasing speed
Inventor: WILL HANS-DIETER ING GRAD
IPC: F02B37/18
Filed: 1977-10-07
Abstract: The system regulates the intake pressure of an IC engine with an exhaust-driven turbo-charger by means of a discharge valve in the engine exhaust upstream of the turbine. This valve is designed to open at a predetermined inlet pressure. The closing force of the discharge valve, opposing the inlet pressure, become less with the engine running under load as engine speed increases. The valve can be spring-loaded shut, the force of the spring being opposed by a vacuum derived from the fresh air current drawn in by the turbo-charger.

Title: Speed controlled commutatorless DC motor - uses electrically operating braking unit to retard motor when nominal motor speed is exceeded by small amount
Inventor: MUELLER ROLF DIPL ING DR
IPC: H02P6/24
Filed: 1977-10-19
Abstract: A speed controlled commutatorless d.c. motor has a permanent magnet rotor. It is designed for as simple as possible a layout of the electronic circuitry used for regulating the motor speed so that controlled braking is initiated by comparison between the nominal and actual motor speed as soon as the nominal motor speed is exceeded by a small margin. To achieve the motor speed control as outlined above, an electrically operating braking unit retards the motor when the nominal motor speed is exceeded by a small amount. More specif. the braking action is achieved by partial short-circuiting of the motor windings.

Title: Sheet pile driving in rock - using pre-positioned explosive changes to shatter internal structure of rock
Inventor: ROSENSTOCK WINFRIED
IPC: E02D5/76
Filed: 1978-03-03
Abstract: Sheet piles are to be driven into a hard rock strata (6) below an overburden (4) beneath a body of water (3).

Title: Pipeline inspection vehicle - having deffect-detector modules spring loaded outwardly and mounted on a ring that can float radially
Inventor: SMITH IAN
IPC: G01N27/90
Filed: 1978-04-14
Abstract: A pipeline inspection vehicle for detecting defects in pipeline walls has a system for supporting a number of defectdetector modules.

Title: Control circuit for windscreen wiper motor - uses control signal delayed by RC timing circuit to close supply circuit
Inventor: JAKOB HEINZ
IPC: B60R16/00
