Abstract: 327,255. Knight, C., and Ackermann, F. Feb. 28, 1929. Amusement apparatus. - A coinfreed machine for playing a game representing investments on the Stock Exchange &c. comprises a disc 1 labelled to indicate various commodities, and rotated during each actuation of the machine to show a different indication in the aperture 7. The coin is inserted in a slot 10 and the machine is operated by rotating the wheel 23, the coins or other articles corresponding td the prize indicated at 7 being removed from the shoot 74. Coin action, weight.-A coin inserted at 10 falls down the shoot 11, Fig. 2, and rests on a stop 12 in which position it maintains a member 15 in tilted position with the part 19 of the member blocking the coin shoot. The tilting of the member 15 withdraws a locking pawl 29 from a pin 28 on a crank disc 27 thereby allowing the operator to turn the knob 23, Fig. 1, and actuate the crank disc by gearing 24, 25. Prize-delivery mechanism.-The rotation of the crank disc 27 tensions a spring 36 which actuates a link 38 and rocks a lever 39 carrying a pin 63 which is adapted to engage the periphery of, or to pass into one of a series of slots 65, 66, 67 in a diso 64 fast on the spindle of the disc 1. The slots are of differing length and control the degree of movement of a slide 68 actuated through linkage 77, 75, 80 by the lever 39. The slide 68 carries three spring pressed pivoted pushers 70b, 71b and 72b one or more of which sweeps through a coin receptacle 21 to deliver coins corresponding in value to the indication in the aperture 7. Simultaneously with the actuation of the slide 68 a spring 53 pulls a link 48 to the right thereby sweeping a spring-pressed pawl 82 over ratchet teeth 1a on the disc 1 and rocking a lever 13 to withdraw the stop 12 from the coin shoot and thus release the inserted coin which falls through a shoot 20 to the receptacle 21, or, if the latter is full, passes thereover to a money box. The release of the inserted coin allows the member 15 to swing into the position shown, thereby looking the crank disc 27 and freeing the shoot 11 for the insertion of a fresh coin. The lever 13, in its movement lifts a shutter 8 by means of a pin 55, till the shutter covers the aperture 7 in which position the shutter is held by a spring-pressed pawl 57 till released by the lever 13 engaging, on its return movement, the nose 62 of the pawl. A dash pot 46 is provided to ensure smooth working and pawls areprovided on the operating mechanism to prevent rotation of the crank disc in the wrong direction. The link 48 on its return movement moves the pawl 82 and rotates the disc 1 to disclose in the aperture 7 the value of the prize, if any, which will be received at the next actuation of the machine.

Title: Automatically released air sea rescue radio device
IPC: H04B1/034
Filed: 1955-03-07
Abstract: 828,896. Signalling-apparatus for marine and aerial navigation. PEEK, C. H. June 7, 1956 [March 7, 1955], No. 6668/55. Class 118 (2). [Also in Groups XXI, XXV, XXXVI and XL(c)] A device for use in locating distressed aircraft, submarines or other vessels comprises a casing 1 containing an automatic radio signal transmitter 2, a power supply 7, a deflated expandible flotation bag 13 and a gas cylinder 15 adapted to inflate the bag 13, and means to cause inflation of the bag and operation of the transmitter operated automatically when the casing is jettisoned from the vessel on which it is carried. A latch member 18 projects from the casing 1 and engages the nose of a bar 20, thereby attaching the casing 1 to the side 11 of the vessel or aircraft against the compression of a coil spring 31. The bar 20 is retained in engagement with the latch 18 against the action of a spring 21 by engagement of the end of the armature 22 of an electromagnet 23 in a recess in bar 20. On energization the electromagnet 23 attracts its armature 22 to allow spring 21 to withdraw bar 20 from latch member 18, whereupon spring 31 ejects the casing 1. A cable 10 secured to the side 11 of the vessel is attached to the end of a three-section telescopic aerial 8 by a shear-pin 9 so that the aerial is automatically extended as the casing is ejected and eventually released by shearing of the pin 9. When the arial 8 is almost fully extended a flared end 32 of its outer member moves rollers 33, 34 outwardly to close switches 35, 36, respectively. Switch 35 completes the circuit from battery 7 to a solenoid 17 which operates a valve 16 allowing compressed gas from cylinder 15 to inflate a rubber bag 13 which bursts a frangible covering-ring 14, of easily torn fabric, for example. Switch 36 supplies battery to transmitter 2 and motor 4 which drives an automatic keying mechanism 5, 6. When the aerial 8 is fully extended the roller 34 moves inwardly past the flared end 32 breaking contact 36 but immediately closing contact 37 on the same switch. A lead weight 38 ensures that the device floats with the aerial upright if it comes down in the sea or takes the shock and assists in bringing the device upright if ejected on land. The casing may be provided with a drogue for descent after ejection, or in the case of use on a submarine the flotation bag should be capable of raising a cable connected to the sunken submarine. A small lamp may be provided on top of the device near the aerial to be switched on with the transmitter and to shine upwardly. The bar 20 is provided with a handle 24 for manual release or the electromagnet 23 may be energized by a remote manually-operated switch or by switches operated on impact or immersion. The circuit of the electromagnet 23 is supplied from battery 7 via brushes 25 on the casing 1 which engage similar brushes 26 suitably mounted on the side 11 of the aircraft or other vessel.

Abstract: 1,067,305. Gas turbine jet propulsion plant. ROLLS-ROYCE Ltd. Feb. 15, 1966, No. 6694/66. Heading F1J. [Also in Division G3] The supply of fuel to the reheat burners (20) Fig. 1, (not shown) of a gas turbine engine is controlled by a valve (32) which is positioned, via linkage (33, 34, 37) and hydraulic control unit (35), by pilot's lever (36), the hydraulic control unit providing the correspondence as between the positions of lever (36) and valve (32) and also serving to ensure that, when the lever (36) is actuated, the valve initially opens to a minor extent only and then, after a predetermined delay, completes any further opening as required by the setting of the lever. With such an arrangement, the predetermined delay allows time for the variable-area nozzle (15) to be adjusted following the selection of reheat on lever (36), thereby preventing burning of the nozzle by the reheat. The control unit 35 comprises a servopiston 47 connected to link 34, a servovalve 44 controlling the supply to servopiston 47, a sleeve 72 slidable in bore 74, a floating lever 67 pivotally connected to the servopiston, the servovalve and the sleeve, and a roller 83 carried by the lever 84 of a delay device 85 and forming a stop for the upper end of lever 67. A second sleeve 75 is slidable in sleeve 72 and carries a link 76 operable by the pilots lever, the latter also being connected to a cam 90 co-operating with a follower 91 formed at one end of a rod 92 connected to lever 67 at 93. If the pilot selects maximum reheat, the cam 90 is rotated through angle 94, portion 95 of which serves to move lever 67 through a distance 87 to abut stop 83. Such movement of the lever causes movement of the servovalve and corresponding movement of the servopiston to open the valve (32) to a small extent. The movement of the pilots lever also moves sleeve 75 to the right to compress spring 81. After a predetermined time, unit 85 releases stop 83 and spring 81 moves sleeve 72 and lever 67 to the right against spring 86. Such movement of lever 67 causes movement of the servovalve and servopiston to allow the latter to complete the opening of valve (32)
