Title: Improvements in or relating to magnetic amplifiers
IPC: H03F9/04
Filed: 1952-01-09
Abstract: 716,387. Magnetic amplifiers. 'SPERRY CORPORATION. Jan. 9, 1952 [Jan. 10, 1951], No. 699/52. Class 40 (4) [Also in Group XXXVIII] Pairs of parallel-connected load windings 14-21 of two saturable reactors 1, 2, constitute the arms of a bridge circuit which has an A.C. supply 31 and a load 26 connected across the diagonals, each pair of windings having oppositely directed rectifiers 22-25 and 32-35 arranged in series so that successive half cycles of current alternate between the two windings. As shown in Figs. 1 and 2, the load windings are distributed on the outer core limbs of the saturable reactors and are so connected in the bridge circuit that the impedances of any two windings constituting a bridge arm are varied in the same sense by a control current in a common winding 13, while the impedances of adjacent bridge arms are varied in opposite senses. The bridge circuit is normally balanced unless a direct current is applied to winding 13. from a control circuit comprising a centre-tapped battery 37 and a variable potentiometer 36. The resultant changes in the impedances of the bridge arms causes A.C. to pass through load 26 which has its magnitude and phase relation with respect to the supply 31 determined by the amplitude and polarity respectively of the control current. In a modified arrangement, Fig. 3, feedback windings 38, 39, are arranged on the central cores of the reactors and are connected in series with load windings 17, 21, to give either positive or negative feedback which is adjustable by potentiometers 42, 43. Bias windings may also be provided on the outer core limbs, Fig. 4 (not shown). In an application to follow-up systems, Fig. 7, the load connected to the bridge circuit comprises a phase winding 60 of a two phase motor 57 which has its other winding connected through a 'phase adjuster to a common A.C. supply 59. The motor drives a load 67 through gearing 68 and a shaft 69 and its direction of rotation is controlled by the polarity of control current in winding 13, correspondence being restored when a driven wiper arm of a potentiometer 65 is coincident with the setting of a potentiometer 62 so that no current from a battery 63 passes through the winding. Specification 710,382 is referred to.

Title: Improvements in or relating to transfer moulding presses
IPC: B29B13/00
Filed: 1954-01-12
Abstract: 747,370. Dielectric heating. WESTERN ELECTRIC CO., Inc. Jan. 12, 1954 [Nov. 12, 1953], No. 858/54. Class 39(3). [Also in Group V] Fig. 3 shows means for heating plastic preforms 102 and feeding them to charging chamber 104 whence they are forced by a hydraulically-operated ram 103 through narrow passages into a mould cavity. The preforms are taken one by one from the bottom of a magazine 108 by a feeder 110 carried by endless chains 111. The feeder pushes a preform from the magazine leftward to a position between an upper highfrequency-heating electrode 112 and a lower earthed electrode 118, and then the feeder (leaving the preform between the eletrodes) retracts to the right, this retraction being effected by a dog 120 on the chains, this dog actuating a switch 121 to reverse an electric motor which drives the chains. When the receding feeder reaches a limit switch 124, it actuates this switch which stops the motor and energises the heater 112. The preform is thus heated for, say, 10-15 seconds, whereupon the motor re-starts to advance the feeder again to the left. The feeder moves the heated preform to the chamber 104, the preform drops into the chamber and the feeder travels around the lefthand chain sprocket until it is out of the way of ram 103, whereupon dog 120 actuates a switch 128 to cause descent of plunger 103 to fill the mould cavity. The chains continue to move, the feeder is carried around right-hand sprocket 117 and takes another preform to the heating station, the feeder retracts, the second preform is heated, and so on.
