Patent DE-3916407-A1 (DE)
Title: Spinning stretching and injection of thermoplastic melt - has good properties in longitudinal direction achieved by spinning stretching and forming of extruded melt at two different stages
Inventor: HENCH HANS
IPC: B29C69/02
Filed: 1989-05-19
Abstract: A device and process for producing polymer extrudates used in conjunction with a conventional injection moulding machine are described Polymer melt is converted after extrusion into polymer strands by the use of a double spinning pump in two separate areas any by stretching and forming rollers.  The strands can be reinforced with continuous fibres of glass, carbon or aramid and are subsequently cut into pellets by the rotating screw of an injection machine. The screw then plasticises, conveys and compresses the polymer melt in the final zone of the injection machine. With some changes the equipment can be applied to all injection machines. USE/ADVANTAGE - (P) produces polymer extrudates with chain alignment along the extrusion direction. High strengths are attained in this direction. Further processing retains the high longitudinal strength in the final product. (P) allows addition of reinforcing fibres.

Title: Blood clotting properties determination - by plunger in orbital motion inside a test vessel and made of specified material
Inventor: HARTERT HELLMUT PROF DR MED
IPC: G01N11/16
Filed: 1989-06-07
Abstract: The clotting properties of blood or blood plasma are determined in a test vessel by a plunger which is excited by magnetic forces to an orbital movement to simulate the natural blood circuit. The amplitude at a constant frequency is measured as a function of time. The detachment of the clots formed from the walls of plunger and vessel is measured and processed to find the adhesivity of the liquid. Specifically a test vessel (1) encloses a plunger (3) at the end of a pendulum (2) which is joined by a steel spring (4) to a measuring tower (5). Magnetic forces stimulate an orbital movement leading to a circular stirring effect and a fibrin tie-up between plunger and vessel. The test vessel and the plunger surfaces in contact with the liquid are made of glass or of a high-wettability plastic. ADVANTAGE - This creates a simple and quickly completed test of great indicative value for diagnostic and therapeutic problems.

Patent DE-3924595-A1 (DE)
Inventor: GESPER CHRISTOPH DIPL ING
IPC: B60R21/01
Filed: 1989-07-25
Abstract: The function of a control arrangement for an occupant restraint system in an automobile is continuously monitored by monitoring circuit. The monitoring circuit checks the frequency of a check signal derived from the microcomputer clock signal using a counting device which is controlled by its own stable oscillator. The monitoring circuit supplies an enable signal to the microcomputer, when such frequency is correct. If the frequency of the check signal is not found to be correct the monitoring circuit supplies a drive signal for the operation of an indicating lamp. At the same time the supply of the trip signal to the trip device is prevented. An error message is produced and the trip signal is suppressed also if the monitoring circuit itself fails.

Title: Fuel preparation for combustion engines and furnaces - by thermal, electrical and magnetic treatment with flow rate taken into account for reduced fuel consumption and gaseous emissions
Inventor: DUEMPERT HORST
IPC: C10G32/02
Filed: 1990-05-09
Abstract: In this method of preparing fuels for combustion engines or furnaces, the fuel is subjected to thermal, electrical and/or magnetic action before it is fed to the engine or furnace.
