Title: Improvements in or relating to direct current-alternating current inverters having a pair of controlled rectifiers
IPC: H02M7/515
Filed: 1966-11-21
Abstract: 1,114,668. Free running semi-conductor inverter. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 21 Nov., 1966 [24 Nov., 1965], No. 52015/66. Heading H3T. [Also in Division H2] In a D.C.-A.C. inverter, having a pair of controlled rectifiers 1, 2 connected between a supply terminal and each end of a centretapped winding 5 and the centre tap connected to the other supply terminal via a choke coil 9 which has an inductance large with respect to each half of the winding 5, a third controlled rectifier 3 is connected so that when starting the inverter it becomes conductive together with one of the main rectifiers 1 to rapidly accelerate the first charging of a capacitor 6 in the parallel tuned circuit 5, 6. The inverter is started by connecting a battery via a pushbutton switch to a pulse shaper 20 which is also supplied from the output 8 of the inverter via a phase control network 24. The zero output from 8 causes a logic device 28 to open gates 31 and 33 and close gate 32 so that triggering pulses are applied to turn on SCR1 and SCR3. The output now obtained at 8 causes the logic device 28 to close gates 31 and 33 and open gate 32 to allow a trigger pulse to turn on SCR2. The SCR's 1 and 2 then conduct alternately under control of gates 31 and 32. The logic device prevents gate 33 opening again until the inverter is required to be restarted. The pulse shaper 20 may be a monostable circuit or blocking oscillator and the logic device and gates may be replaced by two transistors. To ensure correct triggering of the SCR's at high frequencies a bi-stable multivibrator operating as a frequency divider may be connected between the pulse shaper 20 and these two transistors which are connected to the triggering transformers 16 and 17. The inverter may be used for induction heating.

Abstract: 1324264 Treating electrolyte of fuel cells SIEMENS AG 11 Nov 1970 [12 Nov 1969] 53744/70 Heading H1B A method of removing water from the electrolyte of a fuel cell by evaporation utilizes, in the evaporation, heat which has been liberated externally of the fuel cell in the production of a reactant for the cell. Hydrogen peroxide entering a decomposer 1 via orifice 2 is exothermically decomposed by contact with a silver catalyst 3, and the oxygen this formed passes through a ceramic filter 4, which forms a catalyst support, and a porous filter 5. The purified oxygen then passes through heat-exchanger tubes 7 and leaves the decomposer by pipe 6 which leads directly to the cathodes of the cell. Water in the oxygen is condensed in the tubes 7 and removed via pipe 9 after passing through a porous disc 12 which has a capillary pressure for water higher than the oxygen pressure in the decomposer. Electrolyte from a fuel cell battery 13, Fig. 2, enters the decomposer by pipe 10 and is heated by contact with the tubes 7 before leaving via pipe 11 which leads to an evaporator unit in which the water content of the electrolyte is reduced. The evaporator unit may be of various forms but is specifically described as comprising a concentrator 21 in which the heated electrolyte is brought into contact with an inert gas which is circulated by a fan 23. The gas passes through a cooler 24 in which water taken up from the electrolyte is condensed for removal. The electrolyte is taken from the concentrator 21 via a cooler 27 before being returned to the battery 13. The latter is supplied with hydrazine and with oxygen from the decomposer 1 and the electrolyte is KOH. Other arrangements are envisaged in which the heat is derived from the catalytic decomposition of hydrazine, or from the dissolution of metals, e.g. aluminium, or from a hydride of boron or of an alkali or alkaline-earth metal, e.g. LiBH 4 , NaBH 4 , LiH, or CaH 2 .
