Filed: 1973-03-14
Abstract: 1439825 DC-DC conversion DEFENCE SECRETARY OF STATE FOR 22 Feb 1974 [14 March 1973] 12314/73 Heading H2F [Also in Division H4] A known form of night vision device (Fig. 1, not shown) is modified by the addition of an adjustable resistance 8 (Fig. 2) in series with the (dry) battery 4 which powers a transistor oscillator 5 connected via a step-up transformer 6 to a rectifier and voltage multiplier 7 supplying operating voltage for image intensifier tube 1. This arrangement allows an operator to adjust the intensification factor to suit the illumination of the scene, e.g. to reduce the operating voltage supplied to the tube (and hence the intensification factor) when the scene illumination is such as would otherwise produce glare, dazzle and eyestrain. Fig. 3, shows an adjustable resistance 12 together with its operating knob 13 mounted in a special detachable metallic cap 11 of a known metallic cylindrical battery container. One terminal 14 of the resistance is connected by a wire 15 to a brass washer 16 which makes electrical contact with part 11, a second terminal 17 projecting through an insulating disc 18 is soldered to a copper contact disc 19 and a conical beryllium copper spring 20 bearing on disc 19 completes the circuit to one terminal of the battery 9. The latter is positioned within an insulating sleeve 10 inside the battery container.

Abstract: 276,054. Airship Guarantee Co., Ltd., Burney, C. D., and Temple, J. E. May 14,1926. Aerostats; heating; balancing and regulating altitude.-Hydrogen drawn from the aerostats of an airship is consumed in an engine or engines, or in cylinders, separate from those consuming liquid fuel, the hydrogen and liquid fuel engines being so proportioned that the loss of weight due to consumption of liquid fuel is compensated for by the decrease of buoyancy to the consumption of hydrogen. The hydrogen burning unit may constitute one of the main driving units or an auxiliary unit only. It may be used for starting a liquid-fuel engine to the shaft of which it may be connected through a clutch, with or without reversing gear. The auxiliary unit may be similar to an ordinary petrol motor except that it is necessary to use a petrol motor of nominally greater power than that actually required. A suction pump is used in the induction pipe of the hydrogen burning unit, hydrogen being drawn from the gas bags into a hydrogen main which extends longitudinally of the airship, the connections between the bags and main being valve controlled. The exhaust from the hydrogen burning unit is used for warming the passenger or living quarters, and for cooking, and is finally condensed to serve as water ballast. The conservation of the water-vapour in this manner in itself tends to compensate for the loss of weight due to the consumption of liquid fuel, and the size of the hydrogen unit may in consequence be reduced. A keel corridor 8 accommodates ducts for conveying the water-vapour exhaust to the space around the passenger quarters 5 and thence bv pipes 9 to a baffle chamber, containing screens of wire gauze, and to storage chambers.
