IPC: H01H50/64
Filed: 1951-08-29
Abstract: 702,790. Electromagnetic switches. ENGLISH ELECTRIC CO., Ltd. Aug. 22, 1952 [Aug. 29, 1951], No. 20372/51. Class 38(5) A blade spring 21 is arranged between the armature 6 and the contact member 11, which are both pivoted at 13 so that on energizing the magnet 4 the armature moves and the spring 21 is strained while the member 11 is held fast by the co-operation of a permanent magnet 15 and a second armature 14; eventually the armature lever strikes a stop 23 and positively separates the parts 14, 15 whereupon the spring 21 moves the member 11 rapidly into its other position in which a stop 24 is engaged and contacts 9, 18 are disengaged. A weight 25 helps to reduce vibration when the switch is energized by A.C.
Patent GB-204044-A (GB)
Abstract: 204,044. Carter, F. C. Sept. 14, 1922, [Convention date]. Memorandum appliances.-In a cash-recording till, the bill is made out on the vouche-strip V and duplicated on the record-strip S, and the manual withdrawal of the vouche-strip releases the drawer by means of a lever L which also serves to prevent excessive withdrawal. The vouche-strip is supplied from a weighted roll A mounted in inclined slots and bearing against the roller B faced with rubber type inked by a roller C. The strip passes over a guide roll D to the table E where it overlies the record-strip S drawn from a weighted roll F resting on a roller. The record-strip is wound on a roll H bearing against a roller rotated by a belt J from the roller B. The lever L pivoted at T normally rests in a notch in the drawer but when the vcuche-strip is pulled out the rotation of roller B effects through an arm K attached to its axle a clockwise movement of the lever so as to free the drawer. While the latter is open the lever remains in the position shown with a branch M standing in the way of the arm K. The rotation of the roller B under the pull of the vouche-strip is thus limited until the drawer has been pushed in again to cause the lever to free the arm K.

Abstract: 969,738 Change-speed epicyclic gear FICHTEL & SACHS A.G. May 22, 1963 [May 25, 1962], No. 20457/63. Heading F2D. In a two-speed hub comprising planets 5 on an input carrier 6 meshing a fixed sun 4 and ring 7, and pawl and ratchet one-way clutches 16, 17 and 10, 11 between the carrier and ring respectively and the hub shell 2, driver-controlled means retracts the ring pawls 10 for direct drive through the carrier pawls 16, the ring idling, or releases the ring pawls for ratchet engagement for high gear through the ring, the carrier pawls ratcheting. In the hand-shift arrangement of Fig. 1 the ring pawls 10 are retracted for direct drive by a conical annulus 12 acted on by a chain 15, through a pull rod 14 and a thrust block 13, against a spring 29 which acts to release the ring pawls for high gear. In the back-pedal shift arrangement of Figs. 2, 3 a control sleeve 21 has an outer cylindrical part with projections and apertures respectively retracting and releasing the spring pawls. The sleeve rotates with the pawls during forward pedalling, the pawls engaging behind inwardly directed protuberances 23 on the projections during direct drive, and is frictionally held by drag springs 22 during back pedalling so that reverse rotation of the pawl carrier brings the pawls opposite the release apertures for high gear or opposite the projections for direct drive. Alternatively, Figs. 5-7 (not shown), the control sleeve may be replaced by a plate having beaded-over peripheral portions forming the pawl retracting projections.

Abstract: 615,529. Printing. GRETCHIKHINE, N. Aug. 9. 1945, No. 20480. Convention date, Sept. 29, 1941. [Class 100(ii)] Copying documents; platen machines. - In a duplicator particularly for copying book-keeping entries, of the type comprising a cylinder 2 carrying a stereotype or a printing-sheet which is lowered on to the work for printing and is rotated through an angle corresponding to the distance between the lines after each impression, a sheet to be printed is gripped in a carrier comprising a slidable plate 118 and a vertically-movable clamping-bar 122, the carrier being moved horizontally into printing position and opened to release the sheet after printing. The sheet is laid on a table 119 so that one side edge lies between the bar 122 and a flange 118a on the plate 118. The bar 122 carries studs 123 resting on a bar 126 raised to open the clamp against the action of springs 124 by a lever 128 rocked about a pivot 129 by a cam 130 on a main shaft 9. Subsequent to release of the lever and clamping of the sheet, a pin 131 on a disc 132 fixed to the shaft 9 engages a boss 133 on a bar 134 which slides to the right, whereby a pin 136 thereon rocks a lever 137 about a pivot 138, the lever being connected by a rod 140 to the sheet-carrier which moves forward to advance the sheet from A to A<1> ready for printing. A roller 141 on the disc 132 then rocks a lever 143 pivoted at 142 and connected at 144 to a carriage 3 in which the cylinder 2 is mounted, whereupon the cylinder is lowered to print. If only one line is to be printed, the parts return to normal position and the sheet can be removed. Where consecutive lines are to be printed, the carriage 3 is retained in the lowered position by a bolt, and a ledge 3b on the carriage engages a cam surface 137b to prevent return movement of the lever 137 and sheet-carrier. The sheetclamp is, however, released and the sheet is fed forward by the cylinder when advanced by a pawl, the clamp being closed before the next impression.

Filed: 1931-07-21
Abstract: 381,977. Switchgear structures. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, and REGIS, E., 43, Tanfield Avenue, Cricklewood, both in London. July 21, 1931, No. 20831. [Class 38 (v).] In duplicate bus-bar, draw-out switchgear, a lamp or electricallyactuated flap exposing a legend is used to indicate which bus-bars are in commission when the movable part of the gear is in operative position. An arm 10 is pivoted about a pin 11 on or near to the fixed part of the gear and carries a two-way tumbler switch 16 by means of an arm 18, in which slides an actuating member 15 for the switch 16. A lever 12 is pivoted at the end of the arm 10 and carries a projection 13 connected with the slider 15. In action, as the movable part is being moved into engagement with the fixed part, a plugging member for engaging one of the bus-bars engages the lever 12 and rotates it anticlockwise, thereby throwing the switch dolly over and preparing the indicating circuit. The circuit is actually made when the movable part engages the arm 10 and rotates it about the pivot 11, thereby operating a further switch. The lever 12 is held deflected by means of a latch 20 on the arm 10 being moved by the movable part against the bias of a spring 21 into the dotted position in which it obstructs a projection 14 on the lever 12. The parts are self-restoring when the movable part is withdrawn. When the plugging member does not engage the lever 12, the switch 16 remains in the position shown, thereby preparing an indicating circuit for the other bus-bars. If a device such as shown is used on each phase the circuits are interconnected so as to show the operator also that the plugs are all properly inserted.

Title: Improvements in or relating to radar systems
Inventor: THOMAS ALAN JOHN
IPC: G01S13/72
Filed: 1962-05-30
Abstract: 1,030,854. Pulse radar. MARCONI INTERNATIONAL MARINE CO. Ltd. March 6, 1963 [May 30, 1962], No. 20834/62. Heading H4D. A radar system comprises means for preventing normal display of echo signals in a selectable sub-area on the screen of a display cathode-ray tube (C.R.T.), the sub-area including the position of a selected target, and means for displaying a locally generated signal at the target position. The invention is described as applied to a type B display C.R.T. 2 having range interval R and azimuth sector AZ corresponding to an area A marked in a known manner by a tracing circuit 13 on a P.P.I. 1, the " paralysis " area on the B display being e.g. at P. The B-scope X deflection is generated by selection of an " azimuth " pulse in unit 6, a Schmitt trigger 7 and a saw-tooth-wave generator 8; the Y deflection is generated by a pulse delayed from the radar transmitter synchronizing pulse in an adjustable delay unit 9, a monostable circuit 10 and a saw-toothwave generator 11. In order to blank echoes over area P a monostable circuit 18 produces a pulse of duration corresponding to the azimuthal sector of that area on receipt of a trigger pulse from aircraft 14 at a manuallyset or automatically-tracked instant during the saw-tooth-wave, from unit 8, and a monostable circuit 19 produces a pulse defining the range interval of that area on receipt of a trigger pulse from circuit 16 at a manuallyset or automatically-tracked instant during the saw-tooth-wave from unit 11; the pulse in circuit 19 is gated therein by that from circuit 18 and the resultant pulse closes a gate circuit 22 to which the video echo pulses are applied. To give a short pulse at the instant corresponding to the maximum of the echo pulse waveform, a pulse from an Eccles-Jordan (i.e. bistable) circuit 25 is differentiated by a circuit 26 and passed to intensity-modulate C.R.T. 2 via a gate 23 which is opened by the pulse from circuit 19; the video echo pulse passes from a gate 21, opened by the pulse from circuit 19, to reset circuit 25 when the echo signal is at its maximum value, i.e. when the target is on the centre-line of the radar beam. Automatic target tracking.-An Eccles-Jordan circuit 20 changes from one stable state to the other on receipt of the radar transmitter synchronizing pulse and is reset by the gated echo signal from circuit 19 to give a concomitant rapid change of output voltage which causes a capacitor in circuit 17 to commence charging at a fixed rate until the signal from circuit 19 terminates; the D.C. signal from circuit 17 effects automatic range tracking in known manner not described. A similar integrator 15 operating from the circuit 25, is provided for automatic tracking in azimuth. The invention is stated to be particularly useful in marine radar systems, to facilitate avoidance of collisions.

Title: Improvements in and relating to paper pulp beating engines, washing and bleaching engines and the like
IPC: D21D1/02
Filed: 1936-07-28
Abstract: In a beating, washing, or bleaching machine, e.g. for paper pulp or gun cotton, means are provided for supplying pulp water, alum or other fluid to a breast plate in front of the lower part of the roll, the fluid being guided by the plate and fed to the pulp in the trough in front of the roll at the lower part of the breast plate.  The beater comprises trough 1, roll 2 supported on levers 4 and mid-feather 3.  In front of the roll is a cast iron breast plate 5 preferably integral with the trough.  Behind the upper part of the plate is a compartment 6 with entrance opening 7 and outlet 8 to the roll side of the plate.  The floor of the compartment consists of a copper or like plate 9 secured by screws or rivets.  The openings 8 are level with this floor to prevent pulp being caught in the compartment.  The fluid to be added is fed to opening 7 by a pipe, provided if desired with a shut-off valve, and flows down the inside of the plate.  Narrowing openings 5a at each end of the plate prevent lodgment of the pulp between the plate and the side of the trough or the mid-feather.  The roll is driven by an electric motor 10 mounted on slides 11 on girders 12 supported on flanged wall 13 of the trough and pedestal 14 so as to overhang the trough which is covered with boards &c. below the motor, the cover preferably extending from the tail board of the roll cover.  The levers 4 carrying the roll are connected by cross-rods 15, levers 15a and links 15b and are oscillated by hand wheel 16 operating worm gearing 17 and a vertical shaft 18. The shaft 18 is connected to a quick lift hydraulic ram 22 working in a cylinder 23.  This enables the <PICT:0479030/IV/1> <PICT:0479030/IV/2> <PICT:0479030/IV/3> roll to be lifted and returned without interference with the hand setting of the screw adjustment.  In a modification for a concrete trough, the plate is coated with a concrete layer.  In a further modification, the breast plate may be hollow with holes along its bottom edge or the fluids to be mixed with the pulp may be fed from a perforated pipe just above the breast plate. Openings in the lower portion of the breast plate may assist mixing of the pulp.  Specifications 207,716, 261,301, 327,581, [all in Class 96], and 379,547, [Group VIII], are referred to.
