Title: Improvements in and relating to electric winder control systems
Inventor: PROWSE DONALD WINDSOR
IPC: H02P25/26
Filed: 1954-06-01
Abstract: 791,076. Automatic speed control systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1955 [June 1, 1954], No. 16209/54. Class 38 (4). [Also in Group XXXVII] A winding motor 1 has its rotor resistance 2 controlled by means of a pilot motor 3 supplied from an amplidyne 4, a field winding 5 of which is energized in accordance with the speed of the winding motor. For this purpose, a reversing contactor 23 connects a fixed voltage source through resistor 24 to two paralleled branch circuits, one comprising resistor 25 and field winding 5, and the other comprising a variable resistor 27 as well as a tachometer generator 29 driven by the winding motor. An additional' field winding 6 on the amplidyne is opposed to the winding 5 to produce a torque-limiting effect on the winding motor, the winding 6' being supplied from a magnetic amplifier 7 through a reversing contactor 32. The control coil 8 of the amplifier is excited in proportion to the stator current of the motor 1 through a current transformer 12 and a rectifier 12a, the output terminals of the rectifier being shunted' by a variable resistor 14 and fixed resistor 13. A rectifier 10 and reference voltage source 9 are connected in series with the coil 8. When the winding motor is stalled, the resistor 14 is adjusted to provide the required starting torque after the brake has been removed. The removal of the brake short-circuits the section 14, the fixed section 13' remaining in circuit so that the torque is limited to a different value after the winding motor has been started. A single lever may be used to adjust both the resistances T4 and 27, so that, on starting the lever is set to provide the torque necessary to start the load, and, on release of the brakes, the lever is moved' to the required speed position.

Title: Hydraulic control device for a plurality of successive working operations in automatic machines of all kinds, especially stereotype plate casting machines, stamping presses, machine tools and the like
IPC: B41D3/00
Filed: 1934-05-31
Abstract: 437,133. Hydraulic transmission of power. VOMAG BETRIEBS AKT.-GES., Plauen, Vogtland, Germany. May 31, 1934, No. 16287. Convention date, May 31, 1933. [Class 69 (ii)] [See also Group XVI] Hydraulic apparatus for controlling a plurality of successive working operations in automatic machines, especially stereotype plate casting machines, embossing presses, and machine tools comprises a main hydraulicallyactuated valve ; the liquid for actuating the valve passes through one of a number of adjustable throttle devices, so that the speed of valve movement and thus the duration of the intervals between successive working operations varies according to the setting of the individual throttle devices. Liquid from a pump 2 passes through a pipe 11, auxiliary valve 13, and hollow member 21 to the interior of the main control valve 20. The pipe 11 is connected to a pressure relief device 4, and through a throttle 9 and non-return valve 10 to an air vessel 6. The member 21 is suspended by a spring 29, and is moved down by the valve 20 during the final part of the valve movement. The valve 20 has supply and exhaust openings 22, 30, and its casing has conduits 33-52, the conduits 34-52 leading to the cylinders of working pistons 67-71. The supply opening 22 registers successively with conduits 33-44 to effect a cycle of operations in the machine ; at the conclusion of any operation, a machineoperated member 59, opens one or more cut-offs 56, so that liquid is allowed to pass from a conduit, through an adjustable throttle 53, pipe 61, and auxiliary valve 13 to a chamber 64, where it acts to depress the valve 20 to bring the opening 22 into register with the next lower conduit. At the end of the cycle, a hand-wheel 81 is moved axially to engage a coupling 79, 80 to permit the valve 20 to be raised by a pinion and rack 76 ; the axial movement of the wheel causes a lever 16 to be actuated to lower the auxiliary valve 13 so that further supply to the valve 20 is prevented and the chamber 64 is put to exhaust. The rack carries a pointer 85 working over a scale 86.

Abstract: 367,268. Thermal switches. BULPITT & SONS, Ltd. and BULPITT, W. H., Swansea Works, Camden Street, Birming- ham. June 5, 1931, No. 16417. [Class 38 (v).] A safety switch device for electrically-heated utensils is a modification of that described in Specification 329,406 and comprises a pin 7 of square section screwed into an appliance 1 and a catch member 10 with a depending lug at its larger end which enters a recess in the pin 7 and is held by means of fusible metal. A thin metal sleeve 8 fits on the pin 7 and a compression spring is mounted between the two members. The sleeve 8 is held in position by the engagement of a catch 13 on the member 10 with a projection 23 on one side of a slot in the sleeve 8. When the vessel 1 is overheated, the fusible metal melts allowing the member 10 to rotate under the action of the compression spring and the sloping sides 15, 26 of the slot. The sleeve is thus pushed off the pin 7 and forces the socket 4 off the plugs 3 to break the circuit. At the end of its movement, the surface 27 of the sleeve engages the catch 13 to move the member 10 to its original position, and the sleeve may be pushed on again when the fusible metal has solidified.

Patent GB-166279-A (GB)
Abstract: 166,279. Dickinson, H., and Dunn, J. R. Aug. 18, 1920. Transfer mechanism.-In calculating-apparatus of the class described in Specification 12088A/05, comprising a series of stylus-set concentric numbered toothed wheels or rings, the transfer mechanism consists of a lever carrying a spring pawl and moved backwards by the action of a cam operating through an intermediate lever. When the pawl-lever is released, it returns under the influence of a spring and effects the transfer. In the form shown in Fig. 4, the rearward movement of the lever h carrying the pawl k is derived from the lower wheel through a bellcrank lever m, one arm m<1> of which bears on the lever h and the other arm has a pin m<3> lying in the path of an eccentric cam rail n on the lower wheel. Overthrow is prevented by a pawl l pivoted and positioned by a pair of oppositelyacting springs, on the lever h, and controlled as to its engagement with or removal from the toothed wheel by a fixed cam-surface. In the modification shown in Fig. 6, the overthrow is prevented by the spring pawl q, which terminates in a wedge-shaped head r guided by a fixed camrail s. In the construction shown in Fig. 8, the transfer-effecting pawl u<2> is mounted on a lever u provided with an inclined surface u<1> engaged by a. similar surface on a lever t. The transfer pin in its revolution engages a cam v on this lever t and forces it outwards against the action of its spring until the spring clears the cam, whereupon the lever flies inwardly and operates the lever u.

Title: Pulse and radio transmission system
IPC: H03K3/78
Filed: 1944-09-04
Abstract: 590,477. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 4, 1944, No. 16884. Convention date, Aug. 13, 1942. [Class 40 (v)] A radio-transmitter, which is arranged to store up radio-frequency energy and to apply it to a load in the form of widely-spaced short pulses, includes, as an energy-storing circuit, a low-loss transmission line of effective length equal to the width in space of a transmitted pulse and a device coupled across the line to enable the energy to be used by the load. In Fig. 1, an ultra-high-frequency oscillator O feeds energy into a low impedance line TL of ' high Q. The line TL is matched to a load comprising a dipole D mounted in a reflector R. Across the line at point B there is a section of coaxial line T<1>L<1> terminated in a cavity resonator CR, tuned to the frequency of oscillator O. The line T<1>L<1> has a length equivalent to an odd multiple, including unity of a quarter wave-length at this frequency. The cavity resonator CR at this frequency presents a high impedance to the end of line T<1>L<1>, hence the other end of this line presents a low impedance or an apparent short circuit at the point B. When the resonator is detuned by causing the gas discharge tube G to strike, the low impedance presented to line TL at B is changed to a high impedance, so that the energy stored in this line is fed to the load as a burst of power. The pulse duration is equal to the time taken by an electromagnetic wave to travel a distance equivalent to twice the length of line TL from B to C. The discharge tube G strikes at a frequency controlled by an ignition coil switch circuit E. In a modification, the discharge tube G is replaced by a spark-gap, the connections to which are capacitively coupled for radio frequency to the cavity resonators. The transmission line may be a length of coaxial cable, or may be replaced by lumped inductance and capacity. The load circuit may comprise a directive aerial system. Specification 552,482 is referred to.
