Abstract: 817,975. Ventilating aircraft. GARRETT CORPORATION. Dec. 17, 1956 [Dec. 23, 1955], No. 38387/56. Class 137 [Also in Group XIII] In a, system comprising a gas-turbineoperated air compressor and a heat extractor for supplying conditioned air through ducts to a space such as the pilot and passenger cabins of an aeroplane, the air flow through the ducts is regulated by valves at least some of which are controlled in accordance with a predetermined temperatures characteristic of the gas turbine e.g. in accordance with the maximum and minimum permissible working temperatures in a part of the turbine. In the system shown, ram air is compressed in a compressor 13 driven by a gas-turbine 12. A proportion of the air from compressor 13 flows through a duct 19 from which the flow, depending upon the position of the control valves, may be through a by-pass duct 32 or through a heat extractor 20, compressor 25 of a refrigerating unit 21, heat extractor 22 and expansion turbine 26, the air passing ultimately to ducts 30, 31 leading to the cabins. The coolant for heat extractors 20, 22 comprises ambient air circulated therethrough and through ducts 18 by a fan 17. The air flow to the cabins is dependant upon the operation of valves 34, 40, 41, 45 the valves 34, 40 being operated together by means 35 controlled either manually from the pilot's cabin or automatically from the passenger cabin. The valves 41, 45 are so actuated respectively by heat sensitive elements 43, 44 disposed within the gas turbine as to cause the turbine to work within its most efficient temperature range. If air below a predetermined temperature is delivered by the expansion turbine 26 a thermal element 47 in the duct 27 leading from the turbine actuates a valve 48 allowing warm air to flow through a bleed line 50 to the duct 27. A water separator 28 is provided to remove moisture from the cooled air before its delivery through ducts 30, 31 to the cabins. A thermoresistor 46 in the air delivery passage 30 is connected with the control means 35 in the cabins and serves to prevent over-control and excessive fluctuation of the temperature in the cabin.

Abstract: 1,236,768. SCR switching circuit. GENERAL ELECTRIC CO. 16 Aug., 1968 [23 Aug., 1967] No. 39352/68. Heading H3T. [Also in Division H2] A circuit for suppressing the rate of change of voltage across a bidirectionally conductive switching means 13 comprising a semi-conductor controlled rectifier 20 and a rectifying element 21, such as a semi-conductor diode or further semi-conductor controlled rectifier, connected in inverse parallel, has a main suppressing circuit 22 connected directly across the parallel connection comprising a resistor 23 and capacitor 24 and an auxiliary suppressing circuit 25 comprising a resistor 26 and capacitor 27 is connected in parallel with the resistor 23. The voltage suppression circuit prevents the voltage across the thyristor 20 rising rapidly when it is switched OFF. When the current through the diode 21 stops a reverse recovery current of the diode starts and passes through the main suppression circuit 22 which adds to the initial anode voltage transient. In order to limit the excessive dv/dt an auxiliary circuit branch 25 is provided. The resistance of resistor 26 is lower than resistor 23 and the time constant of the auxiliary circuit 25 is made a small fraction, such as less than one-half, of the time constant of the main circuit. For the initial portion of the anode voltage transient on 20 the net resistance in series with capacitor 24 is lowered by the branch 25 to suppress the initial high dv/dt whereas during the remainder of the transient the effective resistance in series with capacitor 24 becomes increased to damp oscillations and limit voltage overshoot. The circuit may be used in an inverter; the control means for triggering the switching means 13 and the particulars of the accompanying power components (rectifier, transformer complementary switching means) are not shown. A capacitor may be connected in series or parallel with the load 12.

Specified materials for layer (a) are either the Se and Te compositions of Specifications 1070411, 1070412 and 1364288 and preferably Se or Se/S which generally change from amorphous to crystalline form on exposure or the compounds of Specification 1405628 and preferably of ferrule which deposits Te on exposure. In the particularly described embodiment, the material is coated on a support with the catalyst layer (c) nearest the support, imagewise exposed to flash light which causes the catalyst and barrier layer to react but has no affect on layer (a) and then heating so that the catalyst can catalyse the charge in layer (a) in the areas corresponding to the imagewise exposure. Specified barrier layers are S, As, arsenic sulphides, or the Se or Te compositions used for layer (a) but having a higher transition temperature for the physical change than the composition used as layer (a); it is also stated that halides such as potassium bromides may be used. The catalyst for layer (c) is preferably a metal such as Ag, Ar, Tl, Hg or Cd for physical change or Ag, Mb, Al or Fe for chemical change but halogens, alkali metals and other catalysts specified in Specification 1364288 may be used to catalyse the physical change in layer (a). A photo-dissociable salt such as Ag I which on exposure produces Ag may be used as a catalyst precursor in layer (c). An image may be formed in layer (a) without a heating step especially when a chemical charge occurs in layer (a). It is also stated that a barrier layer which does not react with the catalyst layer may be used if it charges its transmissivity on exposure and suggests that an azide or a diazo compound may be used in the barrier layer. It is also suggested that there may be reaction between layers (a) and (b) on imagewise exposure to produce a barrier in the exposed areas stopping subsequent transmission of the catalyst.
