Title: Improvements in automatic igniting apparatus for large mercury vapour rectifiers
IPC: H01J13/48
Filed: 1923-08-30
Abstract: 203,679. Akt.-Ges. Brown, Boveri, et Cie. Sept. 7, 1922, [Convention date]. Vapour apparatus, arrangements of.-Automatic igniting apparatus for a large mercury vapour rectifier having an electromagnetically operated igniting anode is feel from a separate source of current not connected electrically with the prima,ry network but closed and opened automatically in dependence upon the primary alternating voltage. In one arrangement, Fig. 1, continunus current is supplied to an igniting anode f and its operating solenoid h by a dynamo g driven by a motor m connected with the secondary winding of a transformer the primary of which is closed when the main switch a is closed. Mechanically coupled switches o, n controlling the motor and dynamo respectively are normally closed by a spring p, but are opened by a solenoid q through which current passes when the rectifier has started. When the anode contacts with the mercury the solenoid h is short-circuited through a lead, not shown, and the anode rises to strike the are. In the arrangement shown in Fig. 2, the motor m is supplied from a low voltage circuit r through a switch s mechanically coupled with the main switch a, and a switch u operated by a solenoid in the rectifier circuit. The switches o, n are closed by a solenoid t when the switches a, s, u are closed, and opened by a spring when the solenoid is de-energized by the switch u.

Title: Improvements in and relating to one-way drives and detents with magnetic locking
IPC: F16D41/12
Filed: 1946-07-23
Abstract: 614,738. Ratchet clutches; positive detents. BRITISH THOMSON-HOUSTON CO., Ltd. July 23, 1946, No. 21948. Convention date, July 24, 1945. [Classes 80 (ii) and 80 (iv)] [Also in Group XXXIV] In a one-way clutch or detent having two relatively rotatable members of magnetic material comprising respectively a wheel and a co-acting friction or positive pawl pivotable to engage or disengage the wheel, one of the members is permanently magnetized and a magnetic force between the members is employed to bias the pawl towards engagement. As shown, the pawl 8, Fig. 3, or 5, Fig. 1, is a centrallypivoted permanent magnet having oppositely polarised ends, and the wheel 7 or 3 is radially polarised so as to attract one end of the pawl and repel the other. With the friction pawl 8, which has a one-way jamming cam surface 9 co-acting with the smooth periphery of the wheel 7, such magnetic interaction biasses the pawl clockwise to initiate jamming. The cam surface 9 may be formed on a hardened insert 18 of non-magnetic material. In the case of the positive pawl 5, the magnetic interaction biasses the pawl anti-clockwise to engage a ratchet end thereon, whose tip 6 may be of non-magnetic material, with ratchet teeth on the wheel 3, whose operative surfaces may also be non-magnetic.. The pawls are mounted on discs 4 and both the pawl 5 and wheel 3, or the pawl 8 only, may be inverted to reverse the direction of locking. The magnetisim of the wheel may be residual, following initial polarisation by temporary energization of a coil 15, Fig. 4, in which case, or if the coil is permanently energized, the polarisation may be reversed by changing the battery connections 17 of the coil so as to magnetically bias the pawl to disengage the wheel. In Figs. 5 and 6 (not shown), permanently magnetized friction and positive pawls respectively are pivoted at one end and may then operate solely by inducing magnetism in the wheel.

Title: Improvements in or relating to load relay circuits for induction motors
IPC: H02H7/085
Filed: 1945-08-27
Abstract: 632,571. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Aug. 27, 1945, No. 21961. Convention date, Aug. 31, 1944. [Class 38 (iii)] A relay associated with the primary circuit of a three-phase induction motor is rendered responsive to the load component only of the line current. The winding a of the relay LR, Fig. 1, is supplied with the vector difference between the current from the current transformer CT-proportional to the total load current, and that from the potential transformer PT-adjustable to a value proportional to the magnetizing current or the no-load current of the motor. Thus the current in winding a is proportional to the actual load component of the motor current. The primary winding of transformer PT is connected to line L2 and through the variable resistor R to the variable tapping on the potentiometer resistance R1 connected across lines L1 and L3. In one modification, transformer CT supplies a second primary winding on the potential transformer, of which the secondary winding is connected in a closed circuit with winding a. In place of winding a the relay may have two windings, Fig. 4, viz : winding i which takes the place of the current transformer CT, and winding j which takes the place of the primary winding of the potential transformer PT, the relay again being energized in accordance with the vector difference between the two currents.
Patent GB-219797-A (GB)
Abstract: 219,797. Phillips, F. E. July 4,1923. Printing on roads.-Apparatus for printing on roads and pavements comprises a type-carrying wheel attached to a vehicle so that it can be operated by the driver of the vehicle to make contact with and print on the road. The typewheel F is supported by a frame E, G, G<1>, G<2> which is pivoted at C, to clamps B, which secure the frame to the vehicle A. A spring L normally serves to keep the wheel F clear of the road, the wheel being lowered into contact with the road so as to print thereon by means of a chain P. Colouring matter is applied to the type from a tank O by an endless band N which passes over guide rollers J<1>, J<2> and also over a wheel R mounted in the tank. A circular brush K serves to remove dirt from the type before the colouring matter is applied. When the wheel F contacts with the road, the band N and its guide wheels are set in motion. In the arrangement shown, the colour is applied from the underside of the belt N, but by placing the tank O on the opposite side of the type wheel, the colour may be supplied from the upper side of the belt. The type are detachably secured to the wheel F by bolts.

Title: Improvements in or relating to methods of and apparatus for grinding flat glass on both faces simultaneously
Inventor: WALDRON FREDERIC BARNES
IPC: B24B7/24
Filed: 1949-08-24
Abstract: 671,961. Grinding sheet glass. PILKING- TON BROS., Ltd. Aug. 24, 1950 [Ang. 24, 1949], No. 22055/49. Class 60. A method of grinding horizontally-disposed flat glass on both faces simultaneously is characterized in that the underface is ground by a rotary disc having an annular series of curved bars, the circumferential width of each bar and the angle which its leading edge makes to a radius at any point increasing continuously from the inner to the outer end of the bar so that abrasive fluid supplied to the centre of the annulus is driven between the bars where, it is subjected to a lifting force which distributes it along the entire length of the upper surfaces of the bars. This lifting force is produced by the configuration of the bars 12, 13 the leading faces of which are inclined to the upper surfaces at an obtuse angle which diminishes continuously from the inner to the outer end of the bar. The abrasive fluid is fed upwardly through a shaft 22 into the centre 17 of the annulus where it is driven outwards into the channels 15 under the combined effect of the hydrostatic head and centrifugal force. The disc is preferably constructed with.a rim 14 having a surface of relatively soft material and is made to a diameter slightly in excess of the width of the ribbon of glass so that connecting channels 16 are progressively uncovered as the disc rotates to allow abrasive fluid to move along the channels 15. If the disc is constructed without a rim, soft metal plugs may be inserted in the channels 15 to regulate the flow. The discs are arranged in co-axial pairs along the length of the glass and use progressively finer abrasive as the polishing stage is approached. In the smooth grinding discs the bars are of the same width as the channels while in the coarse grinding discs they may be twice as wide. The increase in the width of the bars may be from 5 to 10 cms. in proportion to the radius and the increase in the angle of the leading edge from 55 to 70 degrees. On the lower discs the leading face angle varies from 110 to 130 degrees at the centre of the annulus to 93 to 113 degrees at its outer diameter. The upper discs may have a perpendicular leading face since the distribution of abrasive is assisted by gravity. Rollers on opposite sides of the glass feed it between the discs which rotate at about 60 r.p.m.

Title: Improvements in or relating to the continuous-path control of machines, for example machine tools
IPC: G05B19/23
Filed: 1964-05-28
Abstract: 1,069,413. Programmed control of machine tools. SIEMENS-SCHUCKERTWERKE A. G. May 28, 1964 [May 28, 1963], No.22180/64. Heading G3N. In a continuous path control system for a machine, the position of a movable part with respect to the machine is determined by a coil system comprising a movable coil 2, energized in quadrature from a crystal-controlled generator 3 and phase-shifting network 4, and a fixed scale coil 1. The phase position of the induced voltage in the coil 1, representative of the position of the movable part within a scale period, is determined by controlling a gate 7 by opening it by a trigger stage 6, responsive to the generator voltage, and closing it by a trigger stage 5, responsive to the phase-shifted voltage in coil 1. The gate passes pulses representative of the actual value, from a generator 8, synchronized with the generator 3, to a counter 9. The initial count in the counter 9 is adjusted at each measurement by a forward-backward counter 13 into which is fed the desired-value pulses from an interpolator 14. The residual count at the end of a measurement, representative of difference between the desired and actual values is fed to a store 11. Since the travel measuring period is of the order of 2 mm a carry of the correct sign is formed by a device 12, see Fig. 6 (not shown), when the measuring period is exceeded in either sense. The carry modifies the operation of a digital to analogue converter 50 controlling a positional system for the movable part in responsive to the count in store 11 by injecting an additional current of the correct sense.

Filed: 1965-05-27
Abstract: 1,105,507. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 27 May, 1965 [1 June, 1964], No. 22515/65. Heading H4K. The operation of a train of step-by-step or other switches is tested by setting up a connection from an originating test line to a terminating test line under the control of a manually set switch matrix 220. A pulse generator 205 supplies a continuous stream of pulses which are disconnected from the originating line by a relay DG when a pulse counter 216 has counted the appropriate number of pulses in each train as determined by the switch matrix 220 to which relay DG is connected over a sequence switch 212. In the case of the final digit which effects the rotary motion of the connector 106, the connection of relay DG is controlled by a transistor circuit 203 associated with the required terminating line so that, provided the connector is set to that line in response to the correct number of pulses, battery applied over test wiper 109 renders the transistor 223 conducting and relay DG energizes to stop the pulse supply. But if this is not the case, the supply of pulses continues and the connector drives to the last or overflow position, thus avoiding an undesired connection to a subscriber's line. The test set times out and the switch train is held to enable the trouble to be traced.
