Title: Temperature-optimised battery e.g. for electric vehicle drive motors - has thermal switch for fan to cool battery when preset temperature is reached during use and charging
Inventor: BECH JAROSLAV
IPC: H01M10/615
Filed: 1992-02-27
Abstract: A temperature-optimised e.g. Ni-Cd storage battery has a plastic housing enabling good airflow. The housing has labyrinth openings which protect the battery from spray water but allow air exchange. By the housing or within it is a fan, driven electrically via a thermal switch. When a certain temperature is reached through use (around 40 deg C), the switch closes allowing the fan to operate and cool the battery. The user will know that the residual life of the battery is low, but is enough to drive the fan. The subsequent battery charging will be improved by the battery's cool state. The battery temperature will rise again as the fully-charged state is approached and the fan is switched in once more. ADVANTAGE Gives increased battery life, reduces charging time, and allows use in arctic regions.

Patent DE-4227990-A1 (DE)
Inventor: JAECKEL KLAUS DR ING
IPC: H04W84/14
Filed: 1992-08-21
Abstract: The invention concerns a radio-telephone system capable of providing a temporary basic telecommunications service to regions with no coverage or insufficient coverage. Proposed is a system with a stellate operational structure characterized by a fixed base station and a multiplicity of mutually independent subscriber stations. At the base station, the various telephone channels are processed as a frequency-multiplexed signal. This multiplexed signal is preferably superimposed, with angle modulation, on an HF carrier wave and transmitted on a broad-band radio channel. In the direction of transmission from subscriber to base station, the subscriber stations transmit in narrow-band channels which are each of different frequency. For transmission of signalling and control commands, the system includes a special organization channel which is also integrated in the frequency-multiplexed signal. Compared with prior art procedures, this method has the advantage that very high requirements are placed on the intermodulation values of the assemblies and on the stability of the frequency-processing only for the processing of the multiplexed signal in the audio-frequency, i.e. low-frequency, range of the transmitter.
