Title: Improvements in or relating to revolving doors
IPC: E06B3/90
Filed: 1938-03-28
Abstract: 512,074. Door-operating appliances. ELLIOTT, C. A. March 28, 1938, No. 9463. [Class 65 (i)] Apparatus for controlling the movement of a revolving door to prevent it stopping in a deadcentre position comprises a cam 4 rotatable with the door spindle 1 and co-acting with one or more yieldable levers 9, 10 normally maintained in the full-line position shown by a spring 11. One lever 10 is pivoted at 12 to fixed bar 13, the other at 15 to a link 16 pivoted at 17' to the bar. When, during the opening of the door, the cam reaches the dotted line position shown, a roller 7 thereon engages a projection 24 on the lever 9, moving the latter about the pivot 17 so that the link compresses a resilient stop 18 or 19. The reaction of the stop moves the lever 9 back from the dead-centre position and enables the spring 11 to close the door. In the form shown in Fig. 3, the projection 24 on the lever 9 is replaced by a pivoted member 36 swinging between resilient stops 38, 39. A fluid check may be provided, comprising a piston 26 in a cylinder 25, the piston being pressed against the cam 4 by a spring 28. During the closing of the door, the piston moves towards the right, the rate of escape of the fluid through a valve 33 being gradually reduced by the closing of the valve by means of links 34 connected to the piston rod.

Title: Improvements in or relating to seed-sowing machines
IPC: A01C7/10
Filed: 1946-03-27
Abstract: 609.989. Manure and like distributers. ABBEY, A. (Aktiebolaget Westerasmaskiner). March 27, 1946. No. 9491. [Classes C(i) and 58] Relates to seed-sowing machines of the type having a hopper 1 at the base of which delivery rollers 3 feed seed to coulters 21. For determining the rate of sowing, such machines are sometimes provided with a sampling pan 14 which can be swung into or out of operation, the pan being adapted to co-operate with doors in the hopper which deflect the seed away from the drills and into the pan when the latter is in its operating position.- According to the invention, the doors 5 are all connected to a shaft 12 which is engaged by members on pivoted arms 15 by which the sampling pan is mounted on the hopper. In the form shown, rollers 3 expel seed from the hopper 1 over its bottom edge 5' to fall through a seed run 2 into coulters 21. A plurality of bottom doors 10, one to each roller 3, are pivoted to the seed run and are all connected to a shaft 12. The sampling pan 14 is mounted on pivoted arms 15 formed with members 17, 18, which engage the shaft 12 and cause the doors to swing about their pivots 11, when the pan is moved into its operative position (shown dotted), the seed being then deflected into the pan. When it is desired to empty the hopper the hopper bottom 5 can also be swung down by means of a lever 7 to allow the contents of the hopper to fall into the pan. A catch 24 normally retains the pan in a raised position.

Title: Improvements in and relating to protective devices for electric circuits
IPC: H02H7/30
Filed: 1933-03-29
Abstract: 417,183. Protective cut-out systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 29, 1933, No. 9498. Convention date, March 29, 1932. Addition to 399,042. [Class 38 (v).] In the application of the invention described in the parent Specification to a network, a single current-impulse generator is employed and the release-times of the protective relays are graded according to their position in the network with regard to the impulse generator. The relays may be time-delayed and set in operation by the first impulse and when the relay nearest the fault has operated, the remainder restore. Preferably, however, timegrading is made dependent on the number of impulses such that the time decreases the further the relay is from the generator. In Fig. 2, branches a, b are connected to a ring main g and the relays are graded in the manner shown. With an earth fault at f, which is fed from the impulse generator d round both ways of the ring, the longer path will be cut out at the first impulse and the shorter path at the sixth. As the resistance of the longer path may be too great to permit operation of relay 1, the sensitiveness is preferably graded also, the relay with the lowest release-time being the most sensitive. The principle of the ring-main is applied also to parallel feeders, Fig. 3 (not shown), but reduction of the time delay of the relays located in the feeders themselves can be effected by the use of current-unbalance, directional relays e, f, Fig. 4, which only respond to fault current entering the section at the end when the relay is located. To prevent operation by extraneous impulses, further earth-fault relays responsive to a symmetrical current or voltage are provided and may serve to bring the generator d into and out of operation.

Title: Power brake apparatus
IPC: B60T13/24
Filed: 1964-03-06
Abstract: 1,031,356. Fluid pressure brakes. BENDIX CORPORATION. March 6, 1964 [March 11, 1963], No. 9620/64. Heading F2F. In a servo-operated brake master cylinder of the kind in which an hydraulic control pressure, supplied e.g. by a driver-operated master cylinder, is used to operate a control valve 20 for a power cylinder 12, and also acts directly on the hydraulic system of the servo-operated master cylinder, a residual pressure valve 60 in the servo-operated master cylinder includes a poppet valve 74 spring-loaded to close an aperture 68 in a valve body 66 and adapted to open when control pressure exceeds that necessary to crack the control valve, the valve poppet being provided with friction means 78 engaging the wall of an axial passage 70 formed in the valve body to dampen, or prevent, oscillation of the poppet. In the preferred construction the power cylinder 12 is operated by compressed air supplied via inlet valve 26 of a control valve assembly 24 which also includes an exhaust valve 30. The valve assembly is operated by hydraulic control pressure generated by a pedaloperated master cylinder (not shown) which passes via inlet 10 to a chamber containing a piston 18 connected to a diaphragm 34, the latter carrying an exhaust valve seat 32 for engagement with the valve 30 and which normally connects chamber 38 to exhaust, chamber 38 being permanently connected with the power cylinder inlet 42. When hydraulic control pressure increases seat 32 engages valve 30 to close the exhaust connection and subsequently causes valve 26 to crack, admitting compressed air to chamber 38 and hence inlet 42 to move power piston 22 which via rod 58 moves piston 16 in the hydraulic cylinder for servooperation of the brakes. Piston 16 contains a spring-loaded ball valve 52 which is opened by a projection 48 on the rod 58 in the brakes-off position so that the pressure space 56 and inlet 10 are in communication. In the residual pressure valve 60 the body 66 is urged by a spring 62 to press a seal 64 against an opening 59 to retain a small pressure in the brakes, and valve poppet 74 is slidable by ribs 76 in a bore 70 of the body 66 and urged by a spring 92 to close an opening 68 so that pressure in chamber 56 will not open the poppet valve until in excess of that required to crack valve 26. The friction means to damp oscillation of the poppet is a coiled spring 80 having radiating portions 82, 84 which when the spring is inserted in the bore 70 are stressed to engage the bore wall frictionally.

Abstract: 383,527. Road surface markings. LEDOUX, J. A., 50, Houghton Street, Worcester, Massachusetts, U.S.A. April 4, 1932, No. 9622. [Class 3 (ii).] Relates to a road-surface marker of the kind in which a rubber block 20 forming the surface is supported by a metal plate 18 in a casing 10 adapted to be anchored in the road, as by lugs 11. According to the invention the rubber block is removably held in the casing by a latch 24. In assembling, the rubber block 20 and plate 18 are inserted under lugs 21a on the casing ; the latch 24 is inserted in a slot 22 in the opposite end of the rubber block, which is then compressed slightly so that bevelled edges underneath the latch engage lugs 21b on the casing ; and finally the latch is pressed down so as to snap under the lugs. To remove the rubber block and its supporting plate, the bevelled prongs of a fork are pressed down on bevels 29 on the latch so as to enter between the latch and the casing 10, thus compressing the rubber block and allowing it to be removed by levering with a screwdriver on teeth 25 on the latch. A lens 30 may be pressed by a rubber block 36 against the rim 32 of a conical flange 31 raised from the plate 18, the rubber block being carried by a plate 37 having lugs detachably engaging slots in the conical flange.

Title: Spring making machine
IPC: B21F35/04
Filed: 1952-04-17
Abstract: 714,453. Making wire springs. NO-SAG SPRING CO. (GREAT BRITAIN), Ltd. April 17, 1952 [May 25, 1951], No. 9657/52. Class 83 (4). A spring-making machine in which wire 21 is bent sinuously and longitudinally by means 31, 32 and then re-formed longitudinally by a forming shoe 33 has a driven sprocketed roller 36, an idler roller 37 and guide-shoes 72, 73 through which the formed spring passes, and the guide shoes 72, 73 are adjustable in an arcuate path round the rollers so that the spring is held in engagement with a predetermined length of the periphery of one or the other of the rollers in order that its longitudinal curvature may be increased or decreased; in the extreme position of adjustment for decreasing the curvature, shown in chain-dot lines in Fig. 10, the reverse bending may be sufficient to produce a flat spring. The wire is first bent sinuously by a pair of pivoted cam arms 32 co-operating with staggered pins 31 projected by cam means from a forming wheel 26 which is driven intermittently by a worm 28 having a dwell portion and after being bent longitudinally by the shoe 33 passes through a guide 35 and between the guide-shoes 72, 73. The shoes are secured between a pair of supporting rings 65, one of which has notches 82 selectively engageable by a pin 84 on an adjusting member 83 after the shoes have been rotated manually to a position near the required position and then adjustment within a limited range can be made by means of a screw 108 and nut 105 operating a slide 103 engaging a lug 92 on the adjusting member 83. The pin 84 is disengaged from its selected notch 82 by rotating the adjusting member to one extreme position in which it is pivoted slightly by a cam-plate but, in normal operation, a pivoted, hook-shaped block 113 can be placed in position to prevent the nut 105 from moving into this position. A locking bolt 117 holds the screw 108 in adjusted position. The lower roller 36 is driven intermittently by means such as a worm with a dwell portion and has tapered sprockets 45 for engaging the sinuous turns of the spring. The idler roller 37 is grooved to accommodate the sprockets 44 and is mounted on a bell-crank lever 124 pivoted about a removable pin 69 by a lockable adjusting screw 128 for adjusting the gap between the rollers to accommodate different wire gauges and different spacings of the sinuous turns. After leaving the rollers, the wire passes over a wedge-shaped member 138 and is guided between walls 139 to an anvil 145 where it is cut by a crank-operated cutting-mechanism 142 from which the lengths of spring are led away by a guide 146. The space above the walls 139 is relatively unobstructed in order to allow the spring room to curl up if there is an obstruction ahead of it. Markings may be provided to indicate the adjustment of the nut 105 and to assist alignment of the pin 84 and notches 82. U.S.A. Re-issue 23,169 is referred to.
