Title: Vent seal for gas effusion cell - has spring loaded cover plate opened by gas pressure
Inventor: RUMP HANNS
IPC: H01M2/12
Filed: 1990-05-19
Abstract: The gas effusion cell for use in sensor systems has a batery housing with a hole in the top cover. When in operation gas pressure is generated internally with the housing.

Patent DE-4020283-A1 (DE)
Inventor: BOMMER HANS
IPC: C08K3/02
Filed: 1990-06-26
Abstract: A process is described for the preparation of isocyanate-based foams. The foam is usually produced using chlorofluorocarbons (CFCs) as blowing agents. CFC-containing blowing agents can be replaced by alkanes, for example pentane, or water, which forms carbon dioxide. In this case, it is necessary to simultaneously use flameproofing agents. Surprisingly favourable product properties are obtained if, as proposed by the invention, red phosphorus in the form of a phlegmatised paste is used as the flameproofing agent. Even if a comparatively small amount is added, this improves the fire behaviour of the foam.

Title: GTO thyristor overcurrent protection - monitors load current dependent voltage between control electrode and reference potential
IPC: H03K17/0812
Filed: 1990-09-20
Abstract: The overcurrent protection safeguards the GTO thyristor against destruction on switch-off. In the ON state of the thyristor (1), the voltage dependent on load current between a control electrode (7) and the reference potential (10) is monitored. On attaining a preset voltage value, the latter is embossed as control value. The preset voltage value of the control electrode corresponds to a load current, at which the thyristor can be switched off without the risk of destruction. Thus, the load current is limited to a value corresp. to the control voltage. A resistor (9) and a semiconductor component (8) are used for this purpose in specified connection. ADVANTAGE - Simple process for destructive overcurrent limiting.
