Title: Improvements in and relating to separators for secondary cells
IPC: H01M50/437
Filed: 1955-03-11
Abstract: In a battery separator of microporous rubber containing a network of threads, e.g. of glass fibres, the threads extend in channels in the rubber material each having a cross-sectional area sufficiently large with respect to that of the thread within it to allow the threads, or the majority thereof, to slide with some friction in the channels without breaking due to stretching when the separator is bent.  The separator is manufactured by first coating the threads of the network with a substance, e.g. albumin, an organic salt, carbohydrate material such as dextrine, natural resin, synthetic resin such as polystyrene, furfural resin, or a phenolic resin, a highly viscous liquid, e.g. glycerine, or a heavy mineral oil, or a fat, and is then impregnated with a latex dispersion which is gelled and then vulcanized, the initial coating substance being removed from the threads by melting, vaporization, or otherwise during the vulcanization to provide the aforesaid channels.  Specification 739,069 [Group III] is referred to.

March 11, 1932, No. 7343. Convention date, March 11, 1931. [Class 38 (ii).] In an inverter the commutation condenser is connected through a pair of reversely connected valves sothatthemoment of commutation may be controlled and a load having a lagging or leading power factor supplied. In a parallel type inverter comprising valves 14, 15 fed from a D.C. circuit 10 through the primary winding of the output transformer 12, the commutation condenser 16 is connected between the anodes of the main valves through a pair of reversely connected valves 17, 18. The grids of the valves 14, 15, 17, 18 are fed from the secondary windings of a transformer 19 connected across the primary of the transformer 12 through a phase-shifting circuit 20, 21, 22. When the valve 14 is conducting the condenser 16 charges through the valve 17 to the maximum voltage of the primary winding of the transformer 12 and remains charged to this voltage until commutation takes place, this occurring when the valves 15, 18 are rendered conductive. The condenser 16 then discharges to cause commutation of the current from the valve 14 to valve 15. The Specification also describes a three. phase arrangement in which the D.C. supply is bridged by three paths, each path consisting of two valves in series, the mid-points of these parallel paths being connected to the deltaconnected primary windings of an output transformer. Each phase winding of this primary is bridged by a commutation condenser in series with a pair of reversely connected valves. Specifications 219,026 and 230,805, [both in Class 38 (ii), Electric currents, Converting &c.], are referred to. Reference has been directed by the Comptroller to Specification 374,855.

The diode has a lower breakdown voltage than the gate insulation and the resistor increases the time constant of the gate circuit. In a modification, Fig. 6 (not shown), the diode region (71) is shallower than the remaining regions so that its breakdown voltage is lower. The separate diode region 42 may be coinpletely omitted, its function being taken over by the input terminal end 49 of the resistor region 38. In an alternative modification; Fig. 7 (not shown), the diffused resistor is replaced by a resistive layer (85) of aluminium or nickelchromium alloy deposited by evaporation on the insulating layer (87). A parasitic-channel stopper may be provided by forming an N<SP>+</SP> type region (88), doped with phosphorus or antimony, under the deposited resistor. When using a diffused resistor a cross-over may be provided by depositing a conductor (94) over the insulating layer (93) covering the diffused resistor (92), Fig. 8 (not shown). The insulating material may also be silicon nitride. It is mentioned that the resistor may be arranged in series with the source region instead of the gate region, and that the protection arrangement may be applied to other MIS devices by applying a standing bias to the diode or by using two back-to-back diodes.
