IPC: B01F29/62
Filed: 1952-12-19
Abstract: 719,767. Screw conveyers. PHILLIPS PETROLEUM CO. Dec. 19, 1952, [Jan. 2, 1952.] No. 32223/52. Class 78 (1). A screw conveyer 19, particularly suitable for introducing carbon black into a rotating cylindrical mill 10 which forms it into pellets, has a metal cylindrical sleeve 40, shown in perspective in Fig. 3, secured to the outer edge 41 of the blade adjacent each discharge opening ao, 21. Each sleeve is cut away to form a tapered portion 46, the edge 45 of which corresponds to the contour of the edge 41. During each rotation. of the screw, the part 46 uncovers and covers the discharge opening so that for a part of the rotation the material is discharged and for the remainder conveyed by the screw to the next discharge opening. A disc 25, Fig. i, carried by the shaft 17 of the screw, prevents movement of material beyond the last outlet 22. This outlet has no sleeve 40. The mill 10 rests on two sets of rubber tyres 11 driven by a motor 13. The casing 16 of the screw 19 is non- rotatably mounted within the mill and may have scrapers (not shown) on its exterior for removing deposits of material from, the inner surface of the mill. Material is fed to the screw 19 by a screw 14. The pellets pass from the outlet of the mill to a distributing device 28 from which a portion is withdrawn through a conduit 29 and the remainder passed through a conduit 30 to an endless belt conveyer 31. This conveyer returns material to the mill through a hopper 33 and conduit 34, but the parts 33, 34 can be replaced by a conveying device which delivers the pellets to an opening 37 in the tube 16.

A process for producing slub yarn comprises the steps of jetting a compressive gas into a hood 9 to deflect at the bottom of the hood and to escape backwardly, feeding a multifilament yarn in the deflected stream of gas to fold filaments back on themselves at the bottom of the hood, and withdrawing the yarn from the deflected stream of gas through a hole 16 in the hood at a rate at least 0.5% less than the rate of feed, so that the yarn passes through the deflected stream of gas in a countercurrent direction to form slubs composed of filament loops consolidated into the yarn by filament entanglement. The centre of pressure of the jet is preferably displaced from the centre axis of the hood. In a preferred embodiment, the compressed gas is fed into the hood 9 by means of a nozzle 7 having a hole 8 for the entry of yarn into the nozzle for the passage to the bottom of the hood. The yarn may be false-twisted after passage through the hood, the false-twist being effected by means of a fluid vortex jet or preferably by means of an eccentrically mounted friction disk.

Abstract: 1,049,958. Laminates. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 2, 1963, No. 33376/65. Divided out of 1.021,622. Heading B5N. Filaments and/or strands of cellular polymeric material, e.g. expanded polystyrene, which are unconnected or interconnected (but not formed into a network or meshwork) are bonded to or between sheets of material such as paper, cardboard, metal sheet, expanded polystyrene, fibreboard, plasterboard, leather, leather cloth or wood veneers. As an alternative to polystyrene the filaments may comprise interpolymers of styrene with butadiene, acrylic acid, methacrylic acid, the esters or amides of such acids, acrylonitrile or methacrylonitrile, or blends or graft polymers of polystyrene with such materials. In a modification cellular polythene or polypropylene may be used. The filamentary material may contain fillers, colouring matter, stabilizers, lubricants, anti-static agents or plasticizers, or may include fireproofing materials such as halogen compounds or antimony oxide. The cellular filaments may be produced by extruding the heat-plasticized materials containing an expanding agent such as n-pentane and/or a gas-generating composition, either into the atmosphere to produce a fully expanded extrudate or into a cooled and/or pressure zone to effect a partial expansion which may be completed by heating during subsequent laminating operations. Alternatively the filaments may be made by slitting flat expanded sheet material or helically slitting extruded tube. The filaments in the laminate may be straight and parallel or of zig-zag or sinuous form. Paper sheet materials when used may comprise multiple layers, or the laminates made may comprise multi-layers of alternate sheet and filamentary material. The products may be used as panels for constructional partitions or wall and ceiling lining, and be decorated, or for light, resilient packaging material. In examples: (1) parallel rows of ¢ inch diameter cellular polystyrene strands are secured by acrylic latex adhesive to a sheet of “ inch hardboard and a similar sheet adhered to their opposite sides; (2) ¢ inch strands as in (1) are crushed to half their thickness and secured by adhesive between layers of cardboard or cellular polystyrene sheet.

G. ; 376, Prospect Street, East Orange, New Jersey, U.S.A.) Nov. 25, 1932, No. 33427. Convention date, Nov. 25, 1931. [Class 40 (v).] A wireless receiver embodying automatic gain control is provided with sharply tuned selective means for applying energy of carrier frequency to a rectifier the output from which so controls the demodulated output of the receiver that the output is suppressed unless the voltage across the selective circuit exceeds a predetermined minimum. Fig. 3 shows the detector D and low-frequency amplifier AV of a supersonic heterodyne receiver. The radio frequency of the detector is applied through the tuned circuit LC to a rectifier VC1 the direct-current output of which is amplified by valve VT2 and used to negative the prohibitive bias normally applied to the audio frequency amplifier AV. In a modification, Fig. 3 (not shown), the control voltage is taken from a stage preceding the detector. Fig. 4 shows a system in which signals too strong to be adequately controlled by the radio frequency automatic volume control valve RF1 are arranged to increase the bias of the automatic audio frequency volume control valve VC1 to give a smoother control of strong signals. The selectivity of the tuned selective circuit may be modified according to the type of receiver and a relay circuit may be provided to control the output of the audio frequency amplifier. The control may be applied to any point between the detector and the loud-speaker. The Specification as open to inspection under Sect. 91 comprises also arrangements for controlling the audio-frequency amplifier valve from the normal audio detector valve anode current. This subject-matter does not appear in the Specification as accepted.
