Title: Thermoplastic particles
IPC: C09D5/46
Filed: 1964-04-28
Abstract: A plate-like particle of a synthetic thermoplastic resin is characterized by a major dimension of from 5 to 150 mils., a thickness of from 1 to 50 mils., a ratio of major dimension to thickness of from 2 : 1 to 150 : 1, and rounded edges.  The resins specified are polyethylene, polypropylene, polyvinyl chloride, vinylidene chloride-vinyl chloride copolymers, vinylidene chloride-acrylonitrile copolymers, and polyamides, e.g. nylon 66. The particles may be obtained by extrusion of a plurality of strands which are chopped by a large number of knives, the rounded edges being obtained by maintaining the adjacent atmosphere at a temperature sufficient to cause sintering of the particle edges. The particles find application in fluidized bed coating of substrates.ALSO:A method for the coating of a substrate is characterized in that the coating particles employed are plate-like, synthetic, thermoplastic resinous material having major dimensions of from 5-50 mils., thicknesses of from 1-50 mils, ratios of major dimension to thickness of from 2 : 1 to 150 : 1., and rounded edges. The resinous materials specified are polymers derived from ethylene, propylene, vinyl chloride, vinylidene chloride and/or acrylonitrile, and polyamides.  In the example, a steel pipe is coated with polyethylene.  Other substrates specified are fabrics, metal, paper, boxboard, phenolic resin and wood.  The particles may be applied by the fluidized bed process or by flotation coating, or may be dispersed in a volatile medium and applied by brushing, spraying or dipping.

Filed: 1974-04-23
Abstract: 1447303 Valves BRAUKMANN ARMATUREN AG 23 April 1974 [23 April 1973] 17686/74 Heading F2V In an anti-syphon valve normal flow is from an inlet at the top of the valve via an inlet check valve 78 and an outlet check valve 104 which define an intermediate chamber between them. The inlet check valve comprises a closure member 90 which seats on an annular member 56 carried by a flexible diaphragm 60 attached to the valve body.

On rotation of the steering wheel shaft 7, due to the action of a multi-start thread 18, the driven clutch element 20 engages one or other of the members 23A, 23B by which it is driven and in turn drives two or more planet gears 13A, the carrier 12 of which has a pinion 10 formed thereon which meshes with a steering rack 9 or sector. Alternatively, Fig. 4, the clutch driving elements 23A, 23B are provided with external ratchet teeth engaged by pawls carried by 2 sets of eccentrics 53a, 53b, 53c and 54a, 54b, 54c on the driving shaft 24 and the pinion 10 and driven clutch member are interconnected by splines 50 to permit relative axial movement between them. In a further alternative, Fig. 6, the driven clutch element has keyed thereto the pinion 10 and is moved axially, on rotation of the axially-movable shaft 56 to engage one of the clutch driving elements 23A, 23B, by the reaction between the helically cut teeth of the rack 9 and pinion 10. The driving shaft 24 may be driven at a selected one of two speeds or at a speed inversely proportional to the speed of the vehicle in which it is used.

Abstract: 810,056. Transferring electric lamps between machines during manufacture. SYLVANIA ELECTRIC PRODUCTS Inc. June 8, 1956 [June 17, 1955], No. 17844/56. Class 39(2) Apparatus for transferring lamps from a pick-up station to a delivery station comprises a base, an arm pivotally mounted on the base and provided with means for picking up the lamps at the pick-up station and releasing them at an intermediate transfer station and lamp delivery means adapted loosely to receive the lamps of the transfer station before they are released by the pick-up means, to grip and thus accurately position them after release from the pick-up means and to carry them to the delivery station: The transfer machine may be mounted between a sealing machine and an exhaust machine, both operating on the double indexing principle. The lamps 18 are picked up by vacuum chucks 32 carried on arms 30 on shafts 24, which are then turned through 180 degrees by levers 74, 68 operated by cam 64 and moved upwards in their bearings by levers 58, 56 operated by cam 60. At the end of this movement, the vacuum is cut off and the lamps drop into the jaws 120 which are partially closed, and are then closed fully by levers operated by a cam 142. As soon as the jaws are closed, the gear segment 111 driven by the cam 138 causes the arm carrying the jaws 120 to swing through 180 degrees thereby by inverting the lamps. The carriage 94 supporting this mechanism is then moved upwards and the lamps are received by the exhaust heads on an exhaust machine. The jaws 120, Fig. 5, are operated by meshing gears 125 driven by levers 130, 123 actuated by a link 124 driven by an arm 126 on the shaft of a pinion 116. The pinion is operated by a gear segment 112 driven by a rod 140 from the cam 142.

Abstract: 1373576 Production of gaseous fuels R W HENES 19 April 1972 [19 April 1971] 18023/72 Heading F4T [Also in Division B1] Apparatus for producing oxygenated gaseous fuel comprises: a source of pressurized oxygencontaining gas, a first conduit for connecting the source of pressurized gas to the interior of a tank containing liquid fuel at a point below the surface of the liquid fuel, whereby the gas is bubbled upwardly through the fuel to produce oxygenated vapourized fuel in the tank above the liquid surface, and an outlet conduit through which the vapourized fuel passes to a combustor. As shown the source of pressurized gas is supplied from two A.C. solenoid operated compressors 22, 23 compressing ambient air and supplying the compressed air via conduits 24, 25 and 27 to the interior of the tank 20, the gas then bubbling to the surface of the liquid fuel 28. Vapours of the volatile liquid fuel form in the air to provide an oxygenated gaseous fuel above the liquid which passes through the outlet conduit 38 to a flexible conduit 11, the free end of which is attached to a burner (12) or a torch (13) (Fig. 1, not shown).
