Title: Improvements in and relating to means for indicating the speed of alternating current motors
IPC: G01P3/46
Filed: 1926-10-13
Abstract: 283,638. British Thomson-Houston Co., Ltd., and Dreghorn, H. Oct. 13. 1926. Electric and magnetic speed-indicators. - Means for indicating the speed of an alternating- current motor of the type in which the frequency of the flux in the secondary winding is dependent on the speed of the motor comprise one or more coils wound in a slot or slots containing the secondary winding and connected to an indicating device such as a voltmeter of frequency meter calibrated to indicate revolutions per minute. To allow for the small error introduced by variation of the flux with change of line voltage, the indicator may be calibrated for the normal load condition and its readings may be connected to compensate variation in the line voltage. The invention is particularly applicable to alternating- current shunt motors of the type described in Specification 25358/11, [Class 35, Dynamoelectric generators &c.], in which case the indicating meter has two scales, one for hyper and the other for hyposynchronous speeds, the pointer indicating two different speeds at any one position and means being provided for illuminating or otherwise indicating the scale to be used. When a frequency meter is used as the speed indicator, the direction of the phase rotation may be caused to indicate whether the speed is above or below synchronism.

Title: Draw-benches
Inventor: HAMPTON RONALD
IPC: B21C1/16
Filed: 1952-10-14
Abstract: 730,796. Drawing; shearing. PATENTS & INVESTMENTS, Ltd. Oct. 13, 1953 [Oct. 14, 1952], No. 25666/52. Class 83 (4). A work cutting attachment in front of dies 18, Fig. 2, on a draw bench comprises pairs of counter-rotating spindles 11 carrying cutter blades 14 between which the work 20 passes and which are initially moved to engage the work when required so that further drawing movement then effects the continued rotation until the work is severed. Spindles 11 arranged in three pairs are mounted in a slide 10, Fig. 4, movable in guides 16 along the bed 15 of the draw bench and are inter-connected for counterrotation by gears 13 rotatable by a hand-wheel 24. When the work is to be out the operator rotates the hand wheel 24 and rotation is effected automatically until the cutters 14 grip the work. The slide 10 is thereby moved forward until it engages stops 21 which prevent its further movement so that the cutters sever the work. On the return stroke of the drawing head 25 the slide 10 is pushed back to its original position so that the forward ends of the work are exposed for re-engagement by the head. The stops 21 are pivoted at 22 and yieldingly held by springs 23 to permit the head 25 to pass. The cutters 14 are returned to their initial position by a pinion 28 in engagement with a rack 27 on the machine bed. The pinion is mounted in an arm 29 which pivots between stops 31, 32 and disengages itself when the slide is moved forward by the work. In a modification a single pair of horizontal spindles are used, each carrying three cutters mounted opposite the three dies.

Title: Improvements in and relating to spark-fired internal combustion engines
IPC: F02D9/00
Filed: 1953-09-17
Abstract: 739,740. Regulating; cycles; cylinders. MILLER, R. Sept. 17, 1953 [Sept. 23, 1952], No. 25728/53. Classes 7(2) and 7(6). A spark ignition engine comprises means for supplying fuel to the cylinders at a rate which increases with engine load and automatic control means for varying the effective compression ratio, i.e. the ratio of maximum compression pressure on each cycle to the pressure of the charge at the first instant that all the cylinder valves are closed, directly in accordance with engine load, the effective compression ratio at full load being substantially less than the expansion ratio and the fuel-air ratio being maintained substantially constant. In a four stroke gas engine, Figs. 1 and 2, the supply of gas to the engine cylinders through a pipe 26 is controlled according to engine load by a valve 55 controlled by an engine driven governor 54 and the time of closing of the air inlet valve 4, Fig. 1, supplied with air under pressure through a manifold 24 by an exhaust driven turbine 30, Fig. 2, whose output increases as engine load increases, is varied by a device 42 actuated by inlet manifold pressure so that the valve 4 closes progressively later in the suction stroke as the load increases, thereby varying the effective compression ratio in accordance with load. The device 42 comprises a spring-loaded piston 44 subjected to inlet manifold pressure and actuating through a rack and pinion 47, 48 an eccentric 50 which moves a cam roller 15 transversely of the inlet valve cam 17 to vary the inlet valve timing. The compressed air from the blower 30 is passed through a cooler Z and the gas supply manifold 26 is provided with a pressure reduction valve 58, separate adjusting valves 57 being provided on the individual branches of the manifold. The pressure-responsive device 42 may be replaced by an engine-driven governor. In a modification the variation in the effective compression ratio is obtained by arranging that the inlet valve remains open for a varying period at the beginning of the compression stroke so that part of the charging air is forced back into the inlet pipe. Alternatively the excess charging air may be discharged through the exhaust valve or a separate discharge valve and in a two-stroke engine the time of closing of the exhaust ports is varied to vary the effective compression ratio.
