Abstract: 735,278. Loading devices for ordnance. AKTIEBOLAGET BOFORS. Nov. 23, 1953 [Nov. 24, 1952], No. 32441/53. Class 92(1).  A gun on a track-laying vehicle has a waiting tray 15, Figs. 2, 3, rotatable about the elevational axis 16 of the gun to which rounds are fed in a direction transverse to their axes by an elevating device 5, 6 and a loading tray 4 rotatable about an axis 34 parallel to the axis of the gun barrel 2 so that in one position the loading tray can be aligned with the barrel and in another position form a continuation of the waiting tray 15 when the latter is parallel to the barrel. The elevating device comprises two foldable parts 5, 6 hinged tegether with an opening 8 for the supply of rounds and has, internally, upper and lower rails 11, 12 and 9, 10 which are reciprocated longitudinally and have spring-actuated stops 13 so that the rounds 14 can move upwardly past the stops but not backwardly. A round on the tray 15 is maintained in position by a spring-actuated stop 17 and a stop 18 provided with an arm 19 which is actuated by the tray 4 to rotate the stop 18 out of contact with the flange on the round casing. The position of the waiting tray 15 is regulated by a hydraulic jack 20. The front end of the tray 4 is extended as a tube 28 rotatably supported on the gun and having an end flange 30 connected to the ram of a hydraulic jack 31 by which the tray can turn about an axis parallel to the barrel axis. Inside the tube 28 and loading tray 4 extends a piston rod 34 fixed to the bottom wall 27 of the tray and a cylinder 35 slidable over the rod 34 is operated by a hydraulic valve device 36, the cylinder 35 being provided with an arm 39 having a contact device 40 and a spring-urged rotatably mounted claw member 41. A guide arm 43 follows the movements of the claw member 41. A guide rail 44 in the loading tray is provided with a trip member 45 actuated by a spring 46. In operation the waiting tray 15 is first set to receive a round from the elevating device which follows the traverse but not the elevational movements of the gun, and then the tray 15 is positioned so that the round thereon extends parallel to the barrel axis. The cylinder 35 together with the claw 41 is moved forwardly and the whole loading tray then turned so that the lower part of the tray forms a continuation of the waiting tray, this movement disengaging the stop 18 from and engaging the claw 41 with the flange of the round. The cylinder 35 is then moved backwards to take the round with it and the loading tray turned to a position permitting ramming of the round which is effected by moving the cylinder 35 with its attachments forwards when the guide arm 43 will be moved by the guide rail 44 to disengage the claw 41 from the flange of the round.

Title: Improvements relating to the synchronisation of similar polyphase alternating current supplies
Inventor: ADDRISON KENNETH NOEL
IPC: H02P5/46
Filed: 1960-09-22
Abstract: 918,149. Automatic speed control. DE HAVILLAND AIRCRAFT CO. Ltd. Sept. 21, 1961 [Sept. 22, 1960], No. 32530/60. Class 38 (4). Relates to a system for synchronizing the engines of multi-engine aircraft, each engine of which drives a polyphase alternator. The slave alternator 12 supplies stator winding 14 of synchro 16 to produce single-phase current in rotor winding 18. The master alternator 10 has the primary winding 20 of transformer 22 connected across two lines of the output, the single-phase currents from winding 18 and transformer 22 being compared in phasesensitive rectifier circuit 24. If there is a difference of frequency between the alternators the output of circuit 24 comprises a reversible D.C. signal the rate of variation of which is a function of the speed-difference, whilst the level of the signal voltage is a function of phase difference. The signal is applied through amplifier 28 to stator winding 30 of two-phase motor 32 having reference winding 34, rotation of motor shaft 38 producing a feed-back signal in tachometer winding 46 which is passed through phase-sensitive rectifier circuit 48 and amplified in amplifier 50. The signal is phaseadvanced by capacitor 56 and then modifies the supply to the winding 30 to reduce the correcting action of the motor 32. Shaft 60 is driven by shaft 38, the rotor of synchro 16 being driven so that the difference between the frequencies in windings 18, 20, is less than that between the two supplies, so reducing hunting. The shaft 60 also changes the propeller pitch to reduce the speed-difference between the master and slave engines. Alternatively, the shaft 60 may control the fuel supply of the slave engine. In another embodiment, shaft 60 drives rotor 150 to change the coupling between stator windings 146, 148, of a double synchro 144, so energizing transductor windings 156 to correct the speed of the slave engine. Difference in phase due to difference in speed is detected in circuit 124 to operate motor 132 driving stator 142 modulating the output of the double synchro 144. One input to phase-sensitive rectifier circuit 124 is derived from additional transformer 122 connected to generator 10, whilst the other input is derived from generator 12 through synchro 116. The exact phase relationship between the two generators is set by shaft 160 coupled to the single-phase winding 118 of synchro 116. Specification 746,080 is referred to.

Abstract: 718,257. Single-phase induction motors. METZNER, R. G. Dec. 23, 1952, No. 32594/52. Class 35 In an induction motor having four salient, partly shaded poles 1, 2, 3, 4, the opposite poles 1, 2 carry energizing coils 5, 6, which, if 'they are fed with current to produce the same polarity, the machine runs at four-pole speed, while if they are energized to produce opposite polarities, the machine runs with six-pole speed. The circuit for reversing the relative polarity of the field coils 5, 6, comprises resistances 13, 14 and potentiometers 11 by which the polarity of coil 5 can be progressively reduced and then reversed to produce a continuous speed control. With the potentiometer slider at contact 12, both coils 5 and 6 are in series, with resistance 14 limiting the current, and the poles 1, 2 have like polarity so that the machine has four poles. With the slider at 12' the coils are in parallel, with the resistance 13 serving to limit the current, the polarity of field coil 5 being reversed to produce six-pole speed. Specification 670,032 is referred to.
