Title: Improvements in or relating to apparatus for punching record cards
Filed: 1960-04-14
Abstract: 871,286. Punching-record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 14, 1960 [April 16, 1959], No. 13325/60. Class 31 (2). In apparatus for punching holes in statistical record cards, the punching elements move with a card as the holes are punched and the card is scored at hole positions prior to punching by scoring elements which move with the card as the card is being scored. As shown in Fig. 1, holes are scored in a record card 1 by means of rotary members 2, 3 having toothed cutting rings 6, 12 respectively. A resilient ring 9 is disposed between the ring 6 and a hub 8. The member 2 is movable towards the member 3, to score holes in the card, by means of a roller 14 carried by a rocking arm 15 pivoted at one end 16 and connected at the other end to the core 17 of an electromagnet 18. The scored hole portions of the card are punched out by means of spring-influenced tappets 19 carried by a rotary member 4 engaging holes 22 in a rotary member 5. Several members 2, 3 may be mounted on their shafts. In a modification, Fig. 3, record cards are passed successively between two sets of rotary scoring members 23, 24 and 25, 26, before being passed between punching elements identical to members 4, 5, Fig. 1. The rotary members are urged towards the cards by means of control devices 35 to 38. Each control device 41, Fig. 4, comprises a wheel carrying radially-slidable stops 43 held in position by means of studs 44 passing through slots 45 in pivotally-mounted pawls 46. The pawls are rocked clockwise, to move the stops radially beyond the wheel, by means of a pivotally-mounted bell-crank 48, 51, the arm 48 of which is connected by means of a rod 50 with an electromagnet. The projecting stop 43 urges a resiliently-mounted member 39 towards the card to perform a scoring operation. The pawls are rocked counterclockwise to retract the stops, by means of a toothed wheel 54. In a further modification, Figs. 5 and 6 (not shown), each control device comprises pivotally-mounted stops mounted on a rotary member and selectively engaged to rock outwardly from the member by a pawl mechanically connected to the armature of an electromagnet. A still further modification, Fig. 7 (not shown), is described.

Title: Improvements in or relating to high frequency dielectric heating
Inventor: TIBBS CHRISTOPHER EVAN MUNDELL
IPC: H05B6/48
Filed: 1956-05-02
Abstract: 806,248. Protective cut-out arrangements. RADIO HEATERS Ltd. March 8, 1957 [May 2, 1956], No. 13567/56. Class 38 (5). In dielectric heating apparatus having an automatic cut-out to remove heating power from the electrodes when there is an overload, a timing device is arranged to operate after the cut-out has operated and to control switching means whereby power is restored to the electrodes after an interval or at intervals to test whether the overload is still present. The timing device may comprise a synchronous motor having three cams (not shown) to operate contacts A1, B1, C1. In the circuit shown a relay E is normally energized and contacts E1, E2 are closed. The overload trip contacts CT are also normally closed and a relay D is shortcircuited. Power is applied from terminals 14, 16 to a contactor (not shown) controlling the apparatus. When an overload occurs, contacts CT are opened and relay D is energized to change over contacts D1, D2 and open contacts D3. The contacts D1 now short-circuit an indicating lamp 18 and the contactor coil so that power is removed from the apparatus and the contacts CT reclose. The synchronous motor relay F is energized over contacts D2, C1 and starts to run. After two seconds the second cam closes contacts B1 which then remain closed for the remainder of the operating cycle of the motor. After three seconds the first cam opens the contacts A1 for one half second and the relay E is de-energized to open contacts E1, E2. The relay D is now deenergized and changes back contacts D1, D2 and closes contacts D3. When the contacts A1 are reclosed, relay E is energized again and at contacts E1 recloses the contactor coil circuit. If the overload persists, the contacts CT are reopened and the cycle (except for the starting of the motor which is already running) is repeated. After the last opening of the contacts CT, the relay D is energized and at 26 seconds the third cam opens the contacts C1 to stop the motor with the result that the contactor remains open. To reclose the contactor, an " off " push-button 20 is operated to release the relay D. When the supply is restored, the motor is energized by way of contacts B1, D2 and completes its 30 second operating cycle, at the end of which contacts B1 are opened to stop the motor. However, should the overload cease before the full number of reclosing cycles have been made, the periodic opening and reclosing of the contacts A1 has no effect as the contacts CT are not opened, the motor continuing to run until switched-off by the opening of the contacts B at the end of its operating cycle.

Title: Improvements in or relating to rotary apparatus applicable as a motor, pump or compressor
IPC: F01C1/04
Filed: 1928-05-09
Abstract: 290,249. Aktiebolaget Vacuum-Compressor, (Assignees of Berglund, O. R. P.). May 11, 1927, [Convention, date]. Fixed-abutment type; m o u nt i n g rotors on shafts; balancing moving parts; valves, distribnting and cut-off.-In a rotary engine or the like in which a ring piston 5 gyrates in contact with concentric rings 3, 4 on a fixed casing and is carried by a plate 6 which bears on the concentric rings 3, 4 to enclose the working space, the piston is movably mounted on the shaft, and so arranged that rotation of the shaft causes the piston plate and ring to bear tightly against the contacting surfaces. As shown in Figs. 1 and 3 the ring- piston supporting plate 6 has fixed thereon a block 19 which engages a recess in an enlarged boss 22 on the shaft 23 and has wings or lugs 20 sliding in inclined grooves 21 in the boss 22 so that on axial movement of the shaft 23 the piston plate 6 is first moved axially and made to bear on the concentric rings 3, 4 and then moved radially so that the piston ring 5 bears tightly at its contact point. The axial movement of the shaft 23 is obtained by inclined teeth 29 on a ring 26, rotated by an external drive shaft 31, which engage inclined teeth 30 on a sleeve 28 fixed to the shaft 23; alternatively the axial movement may be obtained by an arrangement of helical slots engaging the external drive shaft. To balance the effect of the pressure difference between the inlet and discharge on the plate 6, the latter may be exposed at the side of low pressure to recesses in the bearing surfaces of the fixed rings communicating with the high pressure side. An alternative arrangement is shown in Fig. 1 consisting of a bell 42 pressing on the plate 6 and eccentrically disposed so that high pressure fluid leading past the plate 6 only acts on the outside surface of the plate over the area not enclosed by the bell, this latter area being open to the atmosphere or a vacuum. The piston is controlled by a pivoted link 9. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the provision of grooves 44, 45, Fig. 12 (Cancelled), in the plate 6 which extend across the fixed concentric rings 3, 4 and open into working-fluid supply chambers in the casing. In this modification the combined axial and radial tightening movement of the piston is effected by an obliquely arranged spring 57 in a boss 54 on the shaft. The inner and outer working chambers may be in series and a duplex arrangement may be provided by having piston rings 5 on both sides of the plate 6. This subjectmatter does not appear in the Specification as accepted.

Abstract: 612,840. Gas-turbine plant. BENDIX AVIATION CORPORATION. May 6, 1946, No. 13691. Convention date, May 30, 1945. [Class 110 (iii)] The supply of fuel to a jet-propulsion or other gas-turbine plant is regulated by means of the device shown. Fuel is received at 26 by a fuel pump 27 and a metered flow is delivered at 68. A byepass valve 29 maintains the delivery pressure of the pump 27 above the pressure in the metered flow by a constant value determined by a spring 33. Fuel from the pump delivery chamber 28 passes a fuel valve 39 and a metering valve 42. The position of valve 39 is determined by the differential pressure oh a diaphragm 40, which is the same as the pressure drop past the metering valve, by the differential pressure on a diaphragm 41 produced by a centrifugal pump 48 driven by the turbine and by a spring 52. The pressure in chamber A produced by the centrifugal pump is determined by a leak orifice 51 as modified by a leak orifice 46 which is varied in accordance with atmospheric pressure by means of a capsule 54 and valve needle 55. The metering valve 42 is mechanically connected to the sleeve 57 of a speed-governor 56 and the spring loading of the governor is varied, through connections 63, 64, by the control lever 62. Specification 604,466 is referred to.
