Abstract: 229,956. Mauterer, A. Sept. 19, 1924. Coating - machines. -Objects under water are sprayed with building, protecting, or cleaning materials in solid, liquid, or gaseous form by freeing the object to be treated from water, at the point to be acted on, by means of an air or like blast, and applying the materials through the interior of this space. A device for carrying out the process comprises a nozzle a, surrounded by a bell having an annular aperture c<1> through which compressed air is passed. The. bell may comprise outer and inner casings e<1> and b<1>, the casing e<1> being screwed on to the neck of the casing b' for adjustment of the annular aperture c<1>. Passages f, either direct or inclined, communicate with a hollow space g, through which materials such as trass, water-glass or the like may be supplied, to accelerate, for example, the setting, hardening, adhesion or drying of the materials applied through the nozzle a. Active gases such as carbon dioxide may be supplied through the compressed-air passages.

Title: Method and apparatus for stopping a flyer spinning frame on breakage of a roving
IPC: D01H13/16
Filed: 1976-05-28
Abstract: 1529399 Stop motions TOYODA JIDO SHOKKI SEISAKUSHO KK 28 May 1971 22365/76 Heading DID A photoelectric stop motion stops a flyer machine drive when an abnormal amount of floating fibres around the flyers is detected. The detection is effected by integrating electrical signals from the photoelectric receiver issued when the light beam is interrupted by the floating fibres. As described, the photoelectric stop motion arrangement comprises a light emitter 14 and light receiver 15 positioned adjacent the flyers so as to direct a light beam alongside a row of spinning units but outside the areas in which the flyers rotate. The floating fibres interrupting the light beam cause a variation in the electrical output of the light detector 15. The varying signal is applied to a charge-discharge circuit of a capacitor (see. Fig. 5). The extraneous fibres present during normal operation of the machine do not cause sufficient charging of the capacitor to actuate a relay to stop the machine. The photoelectric device detect an abnormal amount of fibres thrown from a broken end on the packages when by centrifugal force acting on the outermost layer of roving wound on the package. The additional floating fibres cause a higher charge to be applied to a capacitor which stops the drive when a predetermined charge is reached. The rate of charge-discharge of the capacitor may be varied.

Filed: 1964-06-02
Abstract: 1,067,096. Pelletizing hay. MASSEYFERGUSON Inc. June 2, 1964 [June 12, 1963], No. 22699/64. Heading A2B. Hay is wafered by compressing it and passing it through a series of annularly arranged die cells, heating the first part of each die cell to above 300F., and cooling the second part thereof, so obtaining extrusions having a relatively dense thin bonded outer skin and a relatively less dense interior. The annular series of die cells is rotated step by step past the hay compression means, which operates in synchronism to force hay into the die cells successively. As shown, hay is fed, by rotating helix 82, into the compression device 78 whose plunger 84 operates intermittently to force hay into the bottom one of a rotatable annular series of die cells 28. The first part of each die cell 28 is heated, e.g. by thermostatically controlling electric heaters 38. The second part of the die cells 28 project into a stationary cooling device 44 into which air is blown by fan 58 and leaves at 52, the sides of the die cells being perforated to facilitate cooling of the wafers. As the wafers are finally extruded from the ends of the die cells they are deflected by plate 58 so breaking the wafers into short lengths which leave by shoot 60. Alternative methods of heating and cooling are described.

Abstract: 387,714. Controlling consuming devices. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Prince, D. C. ; 1424, Wendell Avenue, Schenectady, New York, U.S.A.) Aug. 12, 1931, No. 22792. Convention date, Aug. 12, 1930. [Class 38 (iv).] In a resistance welding system grid-controlled vapour electric discharge devices control the flow of welding current. An impedance such as that of the primary winding of a transformer 3 has its effective value varied so as to start and stop the current flowing through the welding electrodes 2 by means of a grid controlled discharge device 4, which, in the example shown in the Figure, has a mercury pool cathode. With the control switch 39 open each grid 25, 26 has a negative potential with respect to the cathode by reason of the manner of its connection to a potentiometer resistance 23 connected across the secondary of the transformer 3, to the terminals of which the anodes are connected ; the transformer 3 has no load and its primary winding a maximum impedance. When the switch 39 is closed a potential in phase with the anode potential is applied from a transformer 35 to each corresponding grid, and the discharge device then constitutes a short-circuit on the secondary of the transformer 3 and its primary winding has a minimum impedance. A modification, using two three electrode-valves with indirectly heated cathodes is also described. The control switch may be manually operated or periodically closed, for example by a cam. Discharge devices may be arranged in the welding circuit, and the invention includes half-wave arrangements.

Title: Method of working up scrap or waste aluminium and aluminium alloys
IPC: C01F7/42
Filed: 1950-09-19
Abstract: Waste or scrap aluminium or aluminium alloys are reacted with lead sulphide or lead sulphide-containing material, e.g. galena, and the aluminium sulphide-containing slag so produced is separated from the lead and reacted with water or dilute acid to produce hydrated alumina which is dried, 2calcined, and further worked up, e.g. by fusion electrolysis.  The first treatment may be effected at 900-1000 DEG C. in hearth or short drum furnaces lines with graphite or dolomite or magnesite bricks or with the tamped material.  Silicon carbide material may also be employed as a lining.  The reaction temperature may be controlled by the addition to the reaction of inert material or by the grain size of the reactants.  Prior to tapping the slag, the temperature may be allowed to rise to 1200-1300 DEG C.  The reaction is performed in the absence of air, or in the presence of an inert gas.  Flue dust, which mostly comprises magnesia derived from the alloys, may be recycled.  Hydrogen sulphide evolved in the treatment of the slag may be converted to sulphur or sulphuric acid.  Heavy metal sulphides in the slag are separated by passing the hydrated alumina suspension through a thickener.  Silicon is removed from the slag as sulphide by heating to 1400 DEG C.  Heavy metals may also be present in the lead produced.ALSO:Waste or scrap aluminium or aluminium alloys are reacted with lead sulphide or lead sulphide-containing material, e.g. galena, and the aluminium sulphide-containing slag and lead produced are separated.

A coin-freed vending machine is adapted to receive one or more interchangeable coinaccepting units 3, whereby a coin must be inserted in the or each coin-accepting unit to free the vending machine. As illustrated, the vending machine includes a single coin-accepting unit and three packing-pieces. Each coinaccepting unit comprises plates 8, 9, 10 pivotally mounted between side members 6, 7 by a pin 11 passing through apertures 12, 13, 14. The plates are urged clockwise by springs 15, 16, 17 so that abutments 21, 22 on the upper edges of plates 8, 9 engage the underside 19 of a drawer 2 and the abutment 22 co-operates with a crossbar 20 to lock the drawer in position. A coin inserted between a stud 30 on plate 10 and abutment 23 on plate 9, pivots weighing bar 24 and comes to rest between abutments 27, 28, 29 on plates 8, 9, coupling the plates together. On operation of the drawer the cross-bar 20 acts on abutment 21 and cams the plates 8, 9 away from the cross-bar to free the drawer. The plate 10 prevents the introduction of a second coin at this time. As the cross-bar clears the abutment on plate 9, the plates separate to release the coin into coin box 4. A rack-and-pinion fullstroke mechanism is provided. A spring-loaded cam follower engages a cam surface on the drawer to assist return to the fully closed position.
