Title: Improvements in alternating current systems for the supply of electric motors
IPC: H02J3/30
Filed: 1935-08-16
Abstract: 461,886. Control of A.C. and D.C. motors. ENGLISH ELECTRIC CO., Ltd., and CARNEGIE, H. S. Aug. 16, 1935, No. 23088. [Class 38 (iii)] [Also in Group XXXV] Regenerative braking.-In a system in which a motor is supplied from ar A. C. system in parallel with e second motor driv ing a Siemens Ilgner set which thus has consider a b 1 e momentum the retardation o: the motor on failure of the supply is reduced by means which maintain the two motors con nected together anc the excitation necessary to enable the second motor while driven by the momentum of the Siemens-Ilgner set to operate as a generator supplying energy to the first motor. In the form shown in the Figure an induction motor 1a fed from a supply system 9 drives a Siemens-Ilgner set I comprising a generator 1b and flywheel 5, the generator supplying the driving motor 3 of a reversible rolling mills 4. To the same supply 9 is connected a synchronous motor 2a which drives a Ward- Leonard set 2 supplying the driving motor 7 of a non-reversing mills 8. In the event of failure of the supply a relay 14 locks in the circuit breakers 10, 11 and opens the circuit breaker 13 so that the motor 1a operates as a generator to supply the motor 2a until the momentum of the set 1 is dissipated. In this arrangement the synchronous motor 2a provides the excitation necessary for the induction motor 1a to operate as a generator. In a modification of this to enable the motor 2a to be an induction motor, the excitation is supplied by a separate auxiliary synchronous motor which drives a flywheel and acts as an auxiliary synchronous flywheel generator on failure of the supply. In a further modification the Siemens-Ilgner set 1 is driven by a synchronous motor through a slip clutch to enable the speed to be varied. In a further modification the Siemens-Ilgner set is driven by a synchronous-induction motor which operates as an induction motor during normal running but is changed over to act as a synchronous generator on failure of the supply. The D.C. exciter may be driven by an auxiliary synchronous motor provided with a flywheel.

IPC: F04C28/28
Filed: 1958-07-18
Abstract: 864,493. Rotary compressors. GENERAL MOTORS Ltd. June 16, 1959 [July 18, 1958], No. 23099/58. Class 110 (2). In a sealed motor-driven compressor unit 4, 6 for a refrigerator in which the compressor 6 discharges refrigerant into the casing 2 of the unit, a frangible or flexible valve 50 is disposed between the interior of the casing and the compressor inlet 32. The valve 50 is made of mild steel sheet and is adapted to open to enable the suction side of the circuit and the evaporator 36 to be evacuated. The valve 50 is ruptured or flexed to connect the casing 2 to the said suction side when the pressure thereacross exceeds a given value. When this happens a one-way valve 38 in the suction side closes and a motor starter relay 52 is actuated to stop the motor 4. The valve 50 is held in position by a spring clip 54.

Title: Improvements in and relating to the polymerisation of olefines
Inventor: REED HUGH WILMA BOULTON
IPC: C08F10/00
Filed: 1955-08-11
Abstract: Olefines are polymerized using a catalyst as disclosed in Specification 785,314 and in an inert solvent boiling below 40 DEG C., the solvent being vaporized after polymerization, e.g. by reduction of pressure, to separate the solvent from the polyolefine. The olefine may be ethylene, propylene, butene, styrene or mixtures thereof, and the solvents specified are paraffinic hydrocarbons of up to 5 carbon atoms, e.g. propane and butanes, and inert olefines such as isobutylene.  The solvent may reflux during the polymerization and, further, vaporized solvent may be reliquefied and recycled. Optional promoters, addition of ingredients during polymerization and applications of products are as specified in Specification 785,314. In examples alcohol is used to deactivate the medium after reaction. Specifications 757,524, 762,200, [both in Group IV (b)], and 783,487 also are referred to.

Abstract: 1285135 Angular bending; making tubes GROTNES MACHINE WORKS Inc 13 May 1970 [13 May 1969] 23238/70 Headings B3A and B3E Apparatus for forming a pre-cut blank 11 of metal strip into a tube comprises a rotatable mandrel 16 having a radially extending abutment 33 and clamping jaws 31, 32, a roller guide 30 spaced from the mandrel periphery and parallel to the rotational axis of the mandrel, and a second roller guide 40 parallel to the axis of mandrel rotation and shiftable towards the mandrel periphery. In operation stacked pre-cut blanks 11 are carried by conveyer 12 into an unstacking apparatus 13 having magnetic pickup units 14. A blank is then fed by conveyer 15 over the guide roller 30 into the jaws 31 32, where it is clamped by actuating hydraulic piston 36. The mandrel is rotated by a rack and pinion rotary actuator to draw the blank forward over the roller 30 and wrap it around the mandrel. When the mandrel has passed through approximately 270 degrees of rotation the tracking end of the blank is no longer constrained by the roller 30. At this point the seconf roller 40 is urged against the mandrel and the forming operation is continued until the blank is wrapped completely around the mandrel. The forming process is finished by moving a ram 43 into the space between the roller 40 and abutment 33 after which grippers 50 on a trolley 53 are actuated to remove the formed blank from the mandrel to a flash welding machine. The completed tube is then removed by a gripper 21 on a conveyer 23.

Abstract: 385,660. Golf clubs. SPALDING & BROS. (BRITISH), Ltd., A. G., Deodar Road, Putney, London. - (Assignees of East, J. V. ; Longmeadow, Massachusetts, U.S.A.) Aug. 19, 1931, No. 23327. Convention date, Feb. 14. [Class 132 (ii).] A matched set of golf clubs, wood or iron, has the striking faces 3, 3a, 3b varied from club to club by an inclination of the striking faces with respect to one another about an horizontal axis 4 in the plane of the face which axis is above the sole line 5a and substantially passes through the impact point of the heads. This construction maintains the impact point from club to club at substantially the same distance from the vertical plane 2-2 through the shaft when the club is grounded, so as to give uniformity of timing of impact in the set of clubs. In the matched set the sole face of each club is maintained in the same angular relation with the vertical plane 2-2. In the Figure the sole face 5 is maintained at right-angles to plane 2-2 from club to club.

Classes 79(3) and 136(1) [Also in Group XXVII and XXX] A motor vehicle, e.g. a motor cycle, motor scooter or a three-wheeled vehicle, is lifted by energy from the engine and the descent of the vehicle may be employed to turn the engine for starting (see Group XXVII). As shown, a motor cycle stand is moved into operative position by fluid pressure. When parking the motor cycle the rider leaves the engine running and turns the valve 42 so that it connects ports 40, 36. As the piston 50 reciprocates, fluid is pumped into the cylinder 14 thus displacing the plunger 16. This causes the rear wheel of the motor cycle to be lifted clear of the ground.
