Patent DE-3834005-A1 (DE)
Title: Sensor for measuring changes in the speed of a vehicle, in particular a motor vehicle, in the event of a collision (impact)
Inventor: SCHWANT GUNNAR
IPC: G01P15/093
Filed: 1988-10-06
Abstract: The invention relates to a sensor which makes use of the relative movement of an inertial mass with respect to a vehicle in the event of a collision of a vehicle with an obstacle in order to set a rotatably mounted disc in rotation via a cable. A light beam is provided through openings located in the disc, and interrupted in a pulse fashion during rotation of the disc. An electronic system counts the pulses as a function of time and thereby determines the difference in speed between the vehicle and the inertial mass. <IMAGE>

Inventor: DAUBENBUECHEL WERNER DIPL ING
IPC: B29C48/48
Filed: 1989-07-12
Abstract: The invention relates to a method and an apparatus for manufacturing hollow thermoplastic bodies, the walls of which comprise a laminate having at least two layers, by means of extrusion blow moulding. 
<??>In this method, the pressure within the extruder head, in particular at the point at which the laminate is formed, only undergoes variations which do not have any effect on the laminate impairing its function. In particular, the pressure at the filling-emptying and emptying-filling transition of the accumulator chamber is essentially maintained at a pressure level which corresponds approximately to the discharging pressure.
