Title: Power supply for multi-armature motors
IPC: H02P5/69
Filed: 1962-01-01
Abstract: 932,267. Control of D.C. motors. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 1, 1962 [Feb. 6, 1961], No. 81/62. Class 38 (3). [Also in Group XXXV] With an increase of current supplied to a first armature of a double-armature motor M through transformer T1, a signal is applied to magnetic amplifier MA1 so as to decrease the current through ignitron assembly I1 and more current is fed through ignitron assembly I2 because of a decrease in the output of amplifier MA2. This reaction is reversed when the current through transformer T2 increases in relation to that through transformer T1. Signals proportional to the current fed to each armature are obtained from current transformers CT1, CT2, associated with rectifiers D1, D2. The rectifier D1 energizes windings C1, Cl<SP>1</SP>, whilst the output of rectifier D2 is applied to windings C2, C2<SP>1</SP>. The windings C1 and C2<SP>1</SP> are in opposition, and the windings C2 and C1<SP>1</SP> are also in a differential relation. The amplifiers MA1, MA2 also have reference windings R1, R2, as well as speed-responsive windings S1 S2, associated with pilot generator PG.

Title: Improvements in sheet feeding mechanism
Inventor: BATTEY ALFRED PIERSSENE
IPC: B65H5/20
Filed: 1951-01-01
Abstract: 722,407. Feeding sheets. CRABTREE & SONS, Ltd., R. W. Jan. 1, 1952 [Jan. 1, 1951], No. 106/51. Class 100 (1). Sheet-forwarders.-In apparatus for forwarding sheets one at a time by means including a roller rotated unidirectionally in cycles, the roller is driven by means comprising an endless driven chain having a driving component adapted to engage an abutment in driving connection with the roller, the engagement commencing at one chain wheel and ending at the other. As shown, sheets are separated by a pneumatic sucker 3 from a pile 2 which rests on a table 1 raised intermittently to maintain the top sheet within reach of the sucker. The sucker feeds the sheets between a drop roller 5 and a driven roller 4 which feed them to conveyer belts 5<SP>1</SP> driven at a constant speed. The roller 4 is always driven in the same direction but at varying speeds, such that when a sheet is taken the roller has zero speed; it is then accelerated to a speed corresponding to that of the belts 5<SP>1</SP> for a time sufficient for the latter to take over the sheet, whereafter it is decelerated to zero speed to receive the next sheet. The roller 4 is driven by a chain 6 and sprocket wheel 7 from an output shaft 8 which is driven at varying speeds from a constant speed shaft 9, the latter being driven by chain and sprocket means from a constant speed shaft 13. The shaft 9 extends into a housing 14 wherein it is geared to a shaft having two sprockets 17 therein connected by a double chain 18 to upper sprockets 18<SP>2</SP>. A second double chain 21 connects shafts 24, 25, and the shaft 25 is connected by further chain and sprocket means to the shaft 8. Driving pegs 19, having rollers 20 mounted thereon, are spaced along the chain 18, and the rollers are adapted to engage spaced grooved lugs 26 on the chain 21. As the chain 18 is moved continuously in one direction, one roller 20 passes into engagement with a lug 26 on the chain 21 as the roller is just passing over the centre line joining the, two wheels 17, 18<SP>2</SP>; at this moment the roller 20 has zero velocity component in the direction of the straight run X of the chain. As the roller passes around the wheel 18<SP>2</SP> its velocity component increases to a maximum which is maintained along the straight run of the chain 18 and on passing around the lower wheel 17 the resolved velocity of the roller is gradually decreased to zero. The lugs 26 on the chain 21 are suitably guided and supported during travel.
