Abstract: 649,556. Automatic control systems for D.C. motors; exciting dynamo-electric machines. ENGLISH ELECTRIC CO., Ltd. Oct. 18, 1948, No. 27033. [Classes 35 and 38 (iv)] [Also in Group XXXVII] In a Ward-Leonard system the generator field is automatically adjusted by a control exciter having two opposed fields energized respectively from a fixed supply and a voltage proportional to the motor E.M.F. As shown, the motor 2 is supplied from generator 4, the field winding 4a of which is excited by generator 5 which is itself excited from the tuned amplifying exciter 6. The control winding 6c of generator 6 is supplied from the saturable control generator 11 having two opposed windings 11a, 11b of which the former is supplied from the source 3 and the latter from the motor E.M.F. tapped from the rheostat 13. In order to maintain the exciter 6 in tune independently of any change in temperature of the field winding of generator 5, the winding 6b is energized by unbalance of the bridge 7, 8, 5a, 5b with rise in temperature. Hunting is prevented by the coil 14, which is conductively coupled to the field 4a and which applies a voltage to field 601 upon a change in the excitation of 4.

Patent GB-463561-A (GB)
Title: Improvements in electric timing circuits
IPC: B23K11/24
Filed: 1935-10-01
Abstract: 463,561. Supply systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd., and WHITELEY, A. L. Oct. 1, 1935, No. 27089. [Class 38 (iv)] An electric circuit is energized for a predetermined interval of time from an A.C. source by means of a relay associated with a gridcontrolled discharge tube which is rendered conductive on the actuation of the control device, the period of conductivity being determined by the time taken to charge a condenser in the grid circuit so that it prevents further conduction through the discharge tube. The welding transformer 3 is supplied with A.C. from the mains 1 when the contactor 4 is closed by the relay 5 which is then supplied with rectified A.C. from the mains 1 through the grid-controlled discharge tube 6. Secondary 14 of the transformer 11 heats the cathode while secondary 10 in conjunction with rectifier 12 and smoothing condenser 13 maintains a difference of potential between points A, B and across condenser 9. The cathode is connected to the points A, B through a potentiometer 15 so that the tube is normally rendered non- conducting by a negative grid potential. A weld is initiated by closure of contact 19 which is connected to the electrodes. The consequent current through relay coil 21, while condenser 20 is being charged, closes contacts 22 and discharges condenser 9, thus applying a positive potential to the grid. The tube 6 being thus rendered conductive energizes relay 5 which closes contactors 4 and starts the welding operation. Contactor 23 is opened by the closing of contactor 4 so that condenser 9 is recharged through resistance 16<a> and when the grid potential is sufficiently negative, tube 6 is rendered nonconducting and the welding interval terminates. Specification 435,193 is referred to.

Patent GB-1167985-A (GB)
Title: Improvements in or relating to Hydraulic Change Speed Gears
IPC: F16H39/14
Filed: 1967-06-13
Abstract: 1,167,985. Hydrostatic transmission. CAMBI IDRAULICI BADALINI S.p.A. 13 June, 1967 [15 June, 1966], No. 27241/67. Heading F2C. In a hydrostatic transmission for a motor vehicle wherein concentric variable displacement swash-plate pump and motor units 4, 14 are connected in closed circuit by a distributer plate 13 rotatable with the motor 14, a ring 7 rotatable with the pump cylinder block 4 is interposed between the pump and distributer plate 13 and is urged towards the distributer plate by springs 11 and hydraulic thrust. Notches 16 in the face of the ring 7 ensure that an oil film exists between the ring 7 and distributer plate 13. Rings 9 and seals 10 prevent leakage between the cylinder block 4 and ring 7. The pump cylinder block 4 is fast with an input shaft 3 and carries pistons 6 connected by rods 22 to an aluminium silicon alloy ring 20 which engages a molybdenum insert in a swashplate 21 which rotates with the motor 14. Ducts 27 in the rods 22 supply oil to a recess 28 in the face of the ring 20. Collars 24 on the rods 22 transmit axial thrusts to rings 25 fast with the pistons 6. The swash-plate 21 pivots about an axis 88 offset from the pump axis so that piston reaction urges the plate 21 to its maximum displacement position. Adjustment of the swash-plate 21 to a reduced, zero or reverse displacement positions is effected by supplying pressure oil to pistons (93, 94), Figs. 4, 11 and 12 (not shown), which act directly and through a lever 91 on the swash-plate 21. The motor 14 is fast with an output shaft 82 and carries pistons 41 connected by rods 43 to a ring 45 which transmits axial thrusts to the ends 42 of the pistons and carries runners 47 which engage a non-rotatable swash-plate 50. Ducts in the rods 43 supply oil to recesses 48 in the runners 47. The inclination of the motor swash-plate 50 is varied by a control 122 (not described). When the motor swash-plate is moved to its zero displacement position, for direct drive, a chamber 63 is vented whereupon a spring 62 moves a valve sleeve 60 left into engagement with the distributer 13 to cut hydraulic communication between the pump and motor and thus relieve the motor of pressure during lockup. When the motor swash-plate moves from its zero displacement position the chamber 63 is again supplied with pressure oil and moves right a piston 64 which acts through a thrust bearing 65 on the sleeve 60 which moves right to reconnect the pump and motor. A make-up pump (107), Fig. 3 (not shown), supplies makeup oil to the low-pressure circuit through check valves (Fig. 8, not shown). The make-up pump is normally driven from the input shaft 3 through a one-way clutch 110 and gear 109. During push starting the gear 109 is driven from the output shaft through a one-way clutch 111. In Figs. 7 and 13 (not shown), the pump pistons (30) carry runners (31) which engage the swash-plate (20) and a valve (32) as tube (193) supplies oil to the interior of the runners.
