Title: Improvements in or relating to gun mountings
IPC: F41G1/393
Filed: 1943-11-02
Abstract: 577,907. Gun mountings; sights. RICE, E. A. B., ROSE, A. G., CURTIS, S., NICHOLLS, K. H., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 2, 1943, No. 18109. [Classes 92 (i) and 92 (ii)] Relates to gun mountings of the type in which pivoted movement of the gun or guns is controlled by a sighting arm which controls follow-up mechanism causing the gun or guns to move substantially as one with the sighting arm. According to the invention a locking device is provided comprising one member which remains stationary while the other rotates with the sighting arm, these members being engaged one with the other upon stowing the sighting arm in such manner that they define the neutral position of the sighting arm and lock it in that position. In the construction shown the device is applied to an aircraft gun turret as described in Specification 577,904 wherein a valve 11 for the training oil motor of the turret is mounted in the turret and is controlled by a member 12 movable about. ball bearings 13 coincident with the training axis of the guns. Member 12 is formed with bearings 16 arranged to carry the sighting arm 17. A stud 21 passes through bearing 13 and carries a bracket 121 which is held stationary by being connected to the fuselage of the aircraft by a steel tube. A flange 23 with two radial slots 24 is keyed to the lower end of stud 21 and freely mounted on the flange is a locking member 26 formed with holes 27 ; member 26 is normally held against rotation by toggle levers 61, 62 carrying links 63, 64 which are connected by pins 66, the latter being urged by springs 67 to engage depressions 69 on the inside periphery of member 26. Pins 66 project into the slots 24. When the sighting arm is to be stowed it is moved upwards about bearings 16, and an arcuate track 39 carried by an extension 41 of the arm rides over a pin 38 on a lever 36 until the pin enters a depression 43 in the track. Lever 36 is pivotally mounted on the operating member 12 and, when its pin 38 is caused to enter depression 43 under the action of a spring 42, serves to move a lever 29 having a locking pin 31 adapted to enter one of the holes 27, thus locking the arm in a neutral position. If the pin does not enter a hole 27 in the first instance the sighting arm will " creep " with the turret in one direction or the other until an adjacent hole is engaged. A spring-controlled manual device 47 is provided to prevent movement of lever 36 during normal operation of the turret. The toggle 61, 62 and associated parts prevents damage to the mechanism if an attempt is made to rotate the turret when the sighting arm is stowed, by enabling the ring 26 to rotate if undue pressure is exerted thereon. The number of depressions 69 is a divisor or a multiple of the number of holes 27. Specifications 576,621 and 577,904 also are referred to.

Abstract: 676,924. Refrigerating; tubular heat-exchange elements. HILL & CO., Inc., C. V. July 25, 1950 [Aug. 9, 1949; May 17, 1950], No.18580/50. Addition to 639,313. Classes 29 and 64(iii) In the refrigerating system of the parent Specification in which, during defrosting, a valve 24 is opened to supply hot gas through a pipe 22 direct to the evaporator 12 condensed refrigerant therefrom being evaporated in a reheater 20 over which atmospheric air is circulated by a fan 30, a restricting device 33 is permanently included between the evaporator 12 and the reheater to act as an expansion valve during defrosting. The device 33 is in the form of a valve which is so responsive to the pressure in the suction side of the compressor 2 that, during the refrigerating cycle, it is held open and, during the defrosting cycle when the pressure is higher, it acts as an expansion valve. For the initial part of the refrigerating cycle it also acts to prevent liquid reaching the compressor. The main expansion valve 16 of the system is controlled by a thermal bulb on the suction end of the evaporator 12. The valve 24 is controlled either by a time-switch or by a thermostat in the space subject to the evaporator 12 so that the latter can either heat or cool its surroundings to maintain them at a constant temperature. The condenser 6 and reheater 20 can be disposed in heat-exchange relationship. As shown in Figs. 5 to 7, gaseous refrigerant flows from the compressor 2 through a pipe 8 to flow in parallel through two finned condenser coils 90, 92 from which the partially condensed fluid passes by pipes 96, 98 to a header section 102 of an end header 100 of a condenser-reheater unit 86. It then flows through tubes 112 to and fro between the header section 102 and a section 108 of an opposite and header 106 and passes from a chamber 132 through a pipe 138 to a receiver 10. The cold refrigerated gas (refrigerating cycle) or the refrigerant liquid (defrosting cycle) flows from the device 33 to the bottom of header 106 whence it flows in parallel through tubes 114 passing through the tubes 112 and enters the header 100. It then passes to the compressor through a pipe 142 which cools it to remove superheat. During defrosting, the liquid is evaporated in the tubes 114 by the condensation and freezing of atmospheric water vapour precipitated on fins 118 and pipes 112. This ice is melted at the start of the refrigerating cycle by condensation in the tubes 112 thus accelerating condensation and the condensation is also assisted by cold gas from the evaporator flowing through pipes 114. Tubular heat-exchange elements. (Fig. 7). concentric heat-exchange tubes 112, 114 are connected by webs or loops 116 of conducting material.
