Title: Improvements in and relating to cartridge belt feed mechanism for machine guns
IPC: F41A9/54
Filed: 1935-04-03
Abstract: 603,773. Cartridge feed-mechanism. NASH, A. F. April 3, 1935, No. 10399. [Class 92 (ii)] [Also in Group XIII] For controlling the source of power for feeding a cartridge belt towards a gun, means are provided, whereby the power means is rendered inoperative when the belt has a desired degree of slackness but comes into operation when the slack in the belt has been reduced by firing the gun. As applied to a gun mounted for azimuth movement with rings 7, 9, in an aeroplane structure 11, the belted ammunition passes around a fluted roller 29, whose spindle 28 is journalled in a pair of levers 27, around a second roller 30 (see Group XIII) which is swivelly supported by a plate 32, and thence to a pivotally mounted platen 42 near the breech of the gun. Spent ammunition passes through a guide 43 to the cockpit. When undue tension exists in the belt the platen moves clockwise causing the levers 27 to move anti-clockwise against the action of a spring 22, associated with a lever 19 which, like the levers 27, is connected to a spindle 18 journalled in bearings of fixed side members 17. Such upward movement of the levers 27 causes a flange 44 on the roller 29 to bear against a pulley 45 of a constantly driven hydraulic motor 46, and motion is thus imparted to the belt until the desired degree of slackness is restored when the spring 22 will cause the roller 29 to move away from the pulley 45. The supply of fluid under pressure for the motor may be maintained by the recoil of the gun carriage. Alternatively a spring motor or an electric motor may be used as the source of power.

Title: Improvements in mechanical triggering devices for electric circuits
IPC: H01P5/04
Filed: 1956-04-05
Abstract: 790,535. Waveguide accessories. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 5, 1956 [April 7, 1955], No. 10447/56. Class 40 (8). The electrical characteristics of a U.H.F. circuit, e.g. the resonant frequency of a cavity resonator, the impedance or band-pass of a transmission line are changed by means of a triggering device actuated by an inflammable charge. As shown, the triggering device is adapted to withdraw plungers 2, 3 from a waveguide 1. The plungers are located within guide sleeves 13, 14 and are adjustably attached to a yoke 4. The yoke carries a central sleeve 11 adapted to slide upon a fixed sleeve 12 which houses a spring 29. The outer sleeve 11 keeps the spring 29 in a state of compression and is held in position by a hoop 16 which co-operates with a projection 17 on the sleeve. The limbs 18 of the hoop 16 are attached to horizontallyopposed points on one side of a disc 26 the other side of which carries two plungers 33 fitting within combustion chambers 32. Firing of charges 34 displaces the plungers 33 and releases the hoop 16 from the sleeve 11. This allows the yoke 4 to rise under the influence of the spring 29 and to withdraw the plungers 2, 3.

Abstract: 494,404. Metal - vapour converters. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 7, 1938, No. 10708. Convention date, April 10, 1937. [Class 39 (i)] In a mercury cathode converter which comprises an auxiliary anode arranged inside a screen in the neighbourhood of the cathode to maintain a cathode spot, and a control anode arranged outside the screen to control the point of ignition of the main discharge, an anchoring body for the auxiliary cathode spot is provided within the screen, the screen interior is accessible from the discharge chamber only through an opening immediately above the mercury level, and the control anode is arranged near the opening so that the electrostatic lines of force from the anode pass through the opening into the screen interior. The control anode causes the cathode spot at the moment of ignition to pass through the opening and to form on the mercury outside the screen. The container comprises a glass part 1 and a metal part 2, Fig. 1. The screen comprises a molybdenum or steatite tunnel 8, Figs. 2, 3, at the ends of which are arranged chambers 6, 7 for the auxiliary anode 12 and the control anode 13 which is arranged near the opening 11. An annular anchoring member 5 of nickel extends from within the screen into the discharge chamber and facilitates the movement of the cathode spot. The member 5 forms one wall of the tunnel 8 ; the height of the passage bounded by the tunnel and the mercury surface is greater than the width thereof. Further, the height of the opening 11 is greater than its width. The anode 12 is connected by a rod 14, slidable in an insulating tube 20, to an iron member 15 which is suspended by a spring 16 from a fixed iron member 17. A ferrochromium plate 19 seals the member 17 into an extension of the container. To form the auxiliary cathode spot, the switch 23 which is in series with a resistance 22, magnetic coil 21, anode 12 and the cathode is closed. The control anode 13 is supported by a fixed rod 25 housed within an insulating tube 26. A main graphite anode 29 is supported on a rod 30 which is housed in an insulating tube 31 and is sealed in an extension of the container. A metal screen 34, closed at the top, protects the joint 35 from the discharge. To control the moment of ignition in each cycle, the anode 13 is connected to the source 60 of alternating current through rotary contacts 41 driven by a synchronous motor 39 connected to the source 60. To prevent back ignition, a negative potential may be applied to the control anode 13.

Abstract: 811,047. Drilling. PRATT & WHITNEY CO. Inc. April 3, 1957 [April 17, 1956], No. 10861/57. Class 83 (3). A machine tool comprises variable-speed gearing and electrically controlled clutch means for moving a work or tool support 46 to a preselected position at successively reduced speeds. The rotary table 46 is mounted on a compound slide 32, 26 beneath a vertically movable drill spindle 18. The table rotates on a base 44 about a hollow bush 50, into which may be fitted a plug 52 for use in setting up. Four electromagnets 86 in the base 44 co-operate with a diaphragm 88 on the table to hold it in adjusted position. The rim of the table carries dovetailed dogs 98, each having a'projection 106 which co-operates with an E-shaped magnetic block 108 to produce an error signal whenever the projection is not central over the middle leg of the block, as in the bridge circuit of Specification 607,702. The dogs are adjusted after removing a cover plate 128, against a scale 130. The table is rotated by hand through a wheel 142 and a vernier fine adjustment 144, or by a motor 40, the latter drive being through separate gear drives, selected by electromagnet clutches, to a worm gear 140 on the table. Initially, the dogs are set at the required positions by using the vernier device 144 to position the table, and by adjusting each dog until the error signal derived from the magnetic block 108 is zero, as indicated on a meter 148. When a start button is pressed, the motor 40 is started and the high-speed clutch is energized. The meter 148 is shorted out and the table rotates anticlockwise. When the first index dog contacts a roller on a switch.CLS, a clutch is actuated to slow the table speed. When the switch CLS is released, the table has passed the set position. The third clutch, however, is then engaged and the table rotates clockwise at a slower speed. As the set position is approached, a thyratron fires to energize the lowest-speed clutch. When the zero error signal is produced by exact positioning of the table, the thyratron fires again, a brake is applied to the table drive, the four electromagnets 86 are energized to clamp the table, and a lamp is illuminated. If the table should drift from its position due to cutting pressures &c. the lamp goes out. The operator has then to press buttons to rotate the table in the appropriate direction and to reclamp it.
