Patent GB-2220296-A (GB)
Title: Improvements relating to batteries
Inventor: GILMOUR ALEXANDER
IPC: H01M50/574
Filed: 1989-06-20
Abstract: A battery comprising one or more cells in which a polymeric substance is disposed within at least one of cells so as to act as a thermal fuse or regulator, in the case of excessive heat build-up. The polymeric substance disposed in the cell exhibits good electrical conductivity at normal battery operating temperatures but a substantially reduced electrical conductivity at higher temperatures, for example temperatures above 90 DEG C. The polymeric substance's electrical conductivity may be provided by the inherent properties of the polymeric substance or by loading a basic polymeric substance with a conductive medium, for example, carbon black or aluminium powder.

Title: A frequency synthesiser
Inventor: JOHNSON DAVID ANTONY
IPC: H04L27/20
Filed: 1989-09-22
Abstract: In a modulator for frequency synthesised signals, including a phase lock loop comprising a reference oscillator 8, providing a reference signal to a first input of a phase or frequency comparator 6, a voltage controlled oscillator 2 whose output signal is fed back by way of a variable frequency divider circuit 4 second input of the comparator 6 whose output is applied to a control input of the voltage controlled oscillator, a modulation input signal R is applied to control the output frequency of the voltage controlled oscillator 2 and to control the value N of the variable divider, 4. The operation of the modulator is thus made independent of the actual value N of the divider. The modulation signal is integrated at 24 for controlling divider 4 and applied via a sealer divider 20 to a summing unit 22. The integrated signal is applied via a further sealer 26 to a further summing unit 28 to provide additional adjustment when the value of N is low or the frequency deviation of 2 is small <IMAGE>
