Patent GB-2219589-A (GB)
Title: Microporous halopolymer films
Inventor: DORLING MIKE GEORGE LAND
IPC: H01M50/491
Filed: 1988-06-13
Abstract: A microporous polymeric film of high porosity comprises a halopolymer in which the repeating units are -(CnH2n)- and -(CmX2m)- in which each X independently represents fluorine or chlorine and the values of n and m are greater than one and less than six. The film is the result of firstly melt processing a mixture of the halopolymer, more than 150 parts by weight of an extractable salt and not more than 80 parts by weight of an extractable polymer per 100 parts by weight of the halopolymer, the extractable polymer not being completely and homogeneously mixed with the halopolymer and being less viscous than the halopolymer when both are molten so that the surfaces of the film resulting from melt processing are rich in the extractible polymer, and secondly extracting at least some of the extractable salt to render the film porous and extracting at least some of said polymer to impart surface porosity to the film. The film has a porosity of more than 50 % by volume and more usually 60-70 %. The film may be used as the separator of an electrochemical cell e.g. a battery having a lithium anode and a thionyl chloride electrolyte. It has further been found that high porosities and good electrical properties can be obtained by using as extractable polymer a material having a molecular weight less than one million e.g. a polyethylene oxide of molecular weight about 100,000.

Patent GB-2265061-A (GB)
Title: Radar
Inventor: FAULKNER ALISTAIR ROBIN
IPC: G01S13/32
Filed: 1992-03-06
Abstract: The range of a target is determined using a radar frequency carrier wave modulated by a first, short, code having a first repetition rate and a second code having a bit rate equal to the first code repetition rate. A received echo is first passed to an analogue correlator for correlation against a delayed version of the first code, and the output of the analogue correlator is fed to a digital correlator for correlation therein against the second code. In this way, the high bandwidth (greater range resolution) of analogue correlation can be combined with the lower bandwidth (longer ambiguity function) of digital correlation to provide high resolution target detection without ambiguity and at a fast rate without the need for a very large number of correlators. <IMAGE>

IPC: B01J8/18
Filed: 1992-10-16
Abstract: An improved method is provided for the deposition of high-purity silicon on silicon particles from silicon source gases in a fluidized bed reactor, which is divided into a heating zone 10 and a reaction zone 13 by a partition means 13. Silicon particles in the heating zone are fluidized by a carrier gas such as hydrogen and are heated by microwave 25. On the other hand, the reaction zone for the deposition of silicon, through which reaction gases including the silicon source pass, is heated by particle mixing between the two zones. Subsequently, a desired reaction temperature at the reaction zone is maintained stable without deteriorating the microwave heating of the heating zone. <IMAGE>
