Title: Improvements in or relating to apparatus for orienting articles such as plastic bottles
IPC: B65G47/14
Filed: 1962-05-03
Abstract: 948,230. Orientating bottles. EMHART MANUFACTURING CO. May 3, 1962 [Sept. 29, 1961], No. 17020/62. Heading B85. Plastic bottles B are introduced into hopper 10 and are discharged therefrom and delivered by belt 42, roller 48, and rollers 50 into tube 54, carried by disc 56, which orientates the bottles uniformly and discharges them by air pressure up tube 66. Hopper 10, Fig. 2. The bottom of hopper 10 is formed by a disc 16 surmounted by a cone 22, the two rotating to deliver the bottles B therefrom end to end. Discs 32 are positioned above the bottles as they are discharged from hopper 10 so that bottles on top of each other are engaged and pushed back into the hopper. Orientating tube 54, Fig. 3. The bottles in end to end formation are conveyed by and between rollers 50 to move into tube 54 carried by disc 56 pivoted at 58. The orientation of the bottle is detected by light beams passing transversely to tube 54 and impinging upon light cells 68, 70. These operate in dependence upon whether the neck of the bottle faces forward or backwards, and accordingly operate fluid motors 72 and 74. These in turn move rack 62 up or down so that by engagement with pinion 60 secured to disc 56 the tube 54 is rotated clockwise or anti-clockwise into a vertical position. The bottle now orientated is then discharged by air nozzles 64 up tube 66. The bottle then operates light beams engaging the light cells 112 and 114 to re-establish the fluid circuit of motors 72 and 74.

Abstract: 644,484. Centrifugal separators. SOC. L'ATOMIC. June 25, 1948, No. 17164. Convention date, June 26, 1947. [Class 23] Particles of different size or density, which are to be separated, are introduced through a hopper 21, Fig. 1, into an air stream which enters a vortex chamber 20 through a tangential pipe 22. The mixture passes into the radial passages in a rotor 1 and the smaller or lighter particles are carried with the air stream into a duct 16 leading to a suction pump 17. These particles are, later, separated from the air. The larger or denser particles are thrown out at the periphery of the rotor and fall into a hopper 13. The boss 3 of the rotor is shaped so as to guide the stream to the middle region of the rotor passages. The axial outlet from the rotor is divided by a flared tube 4. The passages in the rotor decrease in cross-section in inverse ratio with the square root of the radius. The boss of the rotor may be of mushroom shape, as in Fig. 8, or pear shape. The rotor may be hung on a shaft passing through the vortex chamber and the shaft may carry fan blades above the rotor. In the form shown in Fig. 8, the casing 55 is part of the rotor and the heavy particles are discharged through peripheral openings 56. In the form shown in Fig. 7 the particles to be separated are entrained in a liquid stream. The liquid carrying the lighter particles enters a vortex chamber 53 and leaves by a tangential outlet 52. The chamber 53 is separated from the outer region of the casing by rings 45 on the rotor which dip into annular troughs 47. Clear liquid is supplied continuously to the intermediate chamber 49. Specification 515,717 is referred to.

Title: Improvements in or relating to methods of indicating electrical quantities
IPC: G08C19/16
Filed: 1944-09-13
Abstract: 581,233. Telemetering systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and STONOR, C. R. P. Sept. 13, 1944, No. 17439. [Class 40 (i)] In a system wherein electric power indications are given in accordance with the rate of impulsing from the spindle of an energy meter, a ratchet 10 stepped by the impulses is coupled by an electromagnetic clutch 11, 12 to a sleeve 13 during successive time periods and the latter transfers its setting to the indicator at the end of each time period. The sleeve 20 of the pointer 17 is normally restrained by a friction brake 22, 23 controlled by an electromagnet 25 and has an arm 19 extending in the path of an arm 16 on the sleeve 13. If, during a time period, the arm 16 overtakes the arm 19, the pointer 17 is driven for the rest of the period. At the end of each period, the electromagnet 25 is energized so that if necessary the pointer 17 is driven backwardly by a spring 21 until the arm 19 engages the arm 16, whereupon the clutch 11, 12 is released and the sleeve 13 is restored by a spring 14 in readiness for the next setting period. Long and short impulses may be employed to distinguish between import and export power by the operation of relays controlling lamps associated with the dial 18, impulses of both kinds being effective on the ratchet 10. Whenever a change of condition occurs, both the clutch and brake are released to zeroize the indicator. Instead of a pointer, a pen may make a record on a moving chart which is displaced bodily when a change of condition occurs. The pointer may also take the form of a wiper which sweeps over two metal segments with an insulating gap, an alarm being given or a correcting device being set in operation by excessive departure of the power load from a predetermined level.
