Title: Improvements in automatic arc striking devices for carbon arc lamps
IPC: H05B31/30
Filed: 1945-01-08
Abstract: 590,710. Are lamps. BRITISH THOMSON-HOUSTON CO., Ltd., and TUCK, F. A. Jan. 8, 1945, No. 644. [Class 39 (i)] In an arc lamp a carbon is fed by coupling the carbon holder 3 to an endless band or chain 6 which passes over three rollers or sprockets 7, 9, one of which drives the chain, and slack may be transferred from one side of the driving sprocket 9 to the other under the control of an electromagnet 13, whereby additional motion is superimposed on the holder. The slack provided in the. chain is taken up by two idler rollers 10, 11 carried on a bracket 12. The bracket arm 16 is coupled to the armature 14 of the electromagnet 13. Current passing through the contacting carbons 1, 2 energizes the electromagnet, thereby effecting anticlockwise motion of the bracket 12 which on transferring slack from one side of the sprocket 9 to the other effects the withdrawal of the carbon 1 to strike the arc. The spring 18 brings the carbons into contact on cessation of the arc, the speed of movement of the carbon being restricted by the dashpot 19. To adjust the position of the carbons when separated, an adjusting screw 20 may be provided to limit the travel of the armature 14.

Title: Improvements relating to small synchronous electric motors
IPC: H02K7/118
Filed: 1945-01-08
Abstract: 588,000. Mechanism for ensuring unidirectional rotation. CHAMBERLAIN - & HOOKHAM, Ltd., JAMES, S., and DEACON, L. O. Jan. 8, 1945; No. 661. [Class 80 (iv)] A device for permitting rotation of a synchronous electric motor only in the desired direction comprises a pivoted double-armed pawl c biassed by a spring d against either of two stops e, and a wheel b driven from the motor and carrying a peg a. On starting the motor, with the pawl positioned as shown, the wheel b may rotate in the clockwise direction, the pawl c being moved idly against spring d when the peg a engages the inclined surface of the pawl. If the motor starts in the wrong direction however the peg a engages a shoulder f on the pawl, rebounds, and rotates in the correct direction. By biassing pawl c against the other stop e, anticlockwise rotation is permitted but not clockwise. Various modifications are described.

Title: Improvements in and relating to synchronous dynamo-electric machines
Inventor: BLASE WERNER
IPC: H02P1/50
Filed: 1964-01-07
Abstract: 987,966. Synchronous machines; control of A.C. motors; converting. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Jan. 7, 1964, No. 746/64. Headings H2A, H2F and H2J. The rotor winding of a synchronous dynamoelectric machine is connected to a polyphase exciter through rectifier elements which are controlled to short-circuit the rotor winding during a starting period and then used to control the excitation current to this winding. The rectifier elements are preferably silicon controlled rectifiers and are mounted for rotation with the shaft of the machine. As shown, synchronous motor 1 has a field winding 3 supplied through a rectifying arrangement, comprising two polyphase fullwave rectifier bridges 64, 65 connected in parallel opposition, from a three-phase generator 60. Centre tapped resistors 66, 67, 68 are connected between pairs of oppositely poled rectifiers of one bridge 65 and the centre taps are connected to the generator output and the corresponding junction point in the other rectifier bridge 64. At starting, the rectifiers are controlled to effectively short-circuit winding 3 through resistors 66, 67, 68 in order to increase the asynchronous starting torque. When the speed has reached a set value the rectifier control is charged to energize winding 3 with rectified current from generator 60 to obtain synchronous operation. In a modification the centre tapped resistors are replaced by resistors placed in both the connections from winding 3 and bridge 65, Fig. 3 (not shown). It is stated that the machine may be de-excited using only bridge 65 and in the starting condition, the rectifiers are controlled with minimum ignition delay by high frequency pulsing. Diodes may be used to by-pass the resistors and normal damping windings provided on the synchronous machine.

Title: Improvements in or relating to thread grinding machines for grinding of conical threads
IPC: B23G1/36
Filed: 1964-01-07
Abstract: 1,049,791. Grinding. HERBERT LINDNER G.m.b.H. Jan. 7, 1964 [April 11, 1963], No. 760/64. Heading B3D. A machine for grinding conical threads comprises a grinding wheel 14, Figs. 1 and 2, in a grinding head 15 which has a continuous feed motion imparted thereto as a function of the longitudinal displacement imparted to a carriage 2 carrying a workpiece 6 by a lead screw 5, the rotary motion of the lead screw being transmitted through change gears 28 to a shaft 35 rotatable in the machine frame and arranged to act on the feed spindle 18 of the grinding head through feed elements co-operating with the shaft and spindle. The workpiece 6 is mounted between centres 7, 8 on the carriage 2, centre 7 being rotatable by a drive from a motor 11 which is also connected by elements 12 and change gearing 13 to the lead screw 5. The lead screw engages a fixed nut 27 in the machine frame, or, alternatively, the lead screw is axially fixed and engages a nut secured to the carriage, and is connected by gearing 29, 30 and shaft 31 to the change gears 28 which, in turn, are connected by shaft 32 and bevel gearing 33,34 to the shaft 35. The latter is keyed to a feed screw 36 which engages a fixed nut 37 and has an abutment engaging the end wall of a cylinder having a piston 25 connected by its rod 26 to a long pinion 23 and the feed spindle 18 of the grinding head. Hydraulic operation of the piston 25 effects rapid traverse by the grinding head which can also be moved manually by rotation of a hand wheel 20 on a shaft 21 having a gear 22 engaging the pinion 23. When shaft 32 is rotated by the change gears 28 driven from the lead screw 5 for the carriage, the shaft 35 is rotated to cause axial movement of the feed screw 36, cylinder 24 and lead screw 18 to move the grinding head as a function of the movement of the carriage, the grinding head moving in a direction corresponding to increased diameter of the workpiece. At the end of the grinding operation, the grinding wheel is lifted clear of the workpiece by rapid traverse effected by operation of the piston-and-cylinder device. In another embodiment, the movement of the grinding head during the conical grinding operation is effected by rotation of the lead screw 18 by a gear 41, Fig. 4, which engages the pinion 23 and is connected by an electromechanical clutch 40 to the shaft 35a from the bevel gearing 33, 34, the clutch being deenergized by actuation of a switch 42 when the hand wheel 20 is depressed to adjust the grinding head manually. Alternatively, the clutch may be operated by push buttons.

Title: Improvements in or relating to magnetic shift registers
IPC: G11C19/04
Filed: 1955-01-11
Abstract: 802,152. Pattern-movement stepping registers. LABORATORY FOR ELECTRONICS, Inc. Jan. 11, 1955 [Jan. 14, 1954 (2)], No. 849/55. Class 106 (1). [Also in Group XXXIX] A magnetic shift register comprises serially arranged bistable magnetic cores each having either a single winding or only two windings thereon, the cores being coupled by unilaterally conductive transfer networks. In the register shown in Fig. 1, employing cores I, II, III . . . n of a material having a substantially rectangular hysteresis loop, each core has a shift winding A and in input/output winding B. Binary " 1s " are entered by applying pulses from terminals 46 to winding B on core I to set the core in a " 1 " state. When the core is reset to the opposite " 0 " state by a shift pulse applied from terminal 21 to the series-connected windings A, a substantial output pulse will be induced in winding B and will charge up temporary storage condenser 31 through diode 22. The condenser will subsequently discharge through resistor 32 and winding B of core II so as to set this core in the " 1 " state. Shifts of the " 1 " to higher stages occur similarly, an output being obtained from the winding B on the last core n. Other types of delay network, e.g. including inductance, may replace the R-C circuits such as 32, 31. In another form of register, Fig. 3, each core has a single winding C which combines the functions of A and B, Fig. 1. The windings C may be replaced by a single conductor threaded through all the cores (Fig. 4, not shown).

IPC: F16K41/00
Filed: 1990-08-16
Abstract: A stop valve assembly comprises two closure members one for stopping substantive gas or liquid flow and the other to prevent leakage along a spindle section (33). Each member possesses a closure element in the form of a rigid disc-like member (9 or 34) of accurately predetermined thickness lying in a recess (1 or 3) formed round the end opening of a duct or around the spindle section and having exactly the same depth as the thickness of the disc. Over the disc outer surface (11), and the end face around the recess is located a flat annular deformable seal member (14, 64); this can be secured at in relation to the disc member, so as to travel with the disc member (9) as a stop valve, or can be secured against the said face around the recess so as to define an antileakage spindle seal. Since no deformed seal is used and since no packing is used in the screw spindle mechanism, high actuating force is unnecessary. The assembly can be operated with a minimum of force to maintain pressures of hundreds or even thousands of pounds per square inch.

IPC: G05B9/03
Filed: 1984-01-06
Abstract: PURPOSE:To constitute a multiple amplification part without deteriorating reliability and power consumption by feeding back signals of the multiple amplification part together, comparing the addition output and a required amplification part output and performing relative operation with a correcting signal, and correcting the amplification part output. CONSTITUTION:The correcting signal from a control part 3 is received by an input resistance 8 and then compared with the sum of an operation signal to a controlled system 6 which is received by a feedback resistance 9 and output currents received by a feedback resistance 14 and voltage dividing resistances 15-17. An operational amplifier 10 performs the operation and then makes corrections as to a voltage/current converter 11 so as to reduce the difference between an operation signal and the correcting signal and the difference between the output currents and correcting signal. The output of the converter 11 flows through a current detection resistance 13 and the potential difference between both terminals is fed back to the amplifier 10 through resistances 14, and 15-17. The output of the converter 11, on the other hand, is summed up and the sum current flows through the system 6 and is reconverted into the voltage signal through a grounding resistance 12. Each amplification part 5 receives this voltage signal as a feedback signal and repeats correcting operation as well as potential differential feedback. Consequently, the partial output charge of each amplification part settles at an equal value with an equal input voltage.
