Filed: 1972-08-09
Abstract: 1437322 Extruding striped soap PROCTER & GAMBLE Ltd 9 Aug 1973 [9 Aug 1972] 37164/72 Heading B5A A soap or synthetic detergent bar, having longitudinally or spirally extending stripes of at least one distinctive colour, is extruded from a screw extruder having a vacuum inlet to which the soap is delivered from a further extruder having a perforated plate outlet at which an aqueous solution or dispersion of the colouring matter is injected into the soap, within at least one of the plate perforations. A rotating knife cuts the strands from the perforated plate to fall into the bar inlet of the bar extruder. The injected solution or dispersion may include stated additives. Extrusion of the bar is effected via a pressure plate, and tapering nozzle within which vanes may be located to impart a rotational motion yielding spirally aligned stripes in the bar. The stripe appearance may be enhanced by shaving a surface layer of the extruded bar. The injection is effected within a plate perforation 14 from a fine mesh or sintered metal nozzle 18 incorporating a spring loaded non-return valve. The perforation 14 is larger than the remaining perforations, and the increased fluidity of the soap into which injection has been effected is counteracted by a mesh or perforated plate 16, from which the strands issuing are cohered by a restricting orifice 17. A mesh may also be provided at the inlet to perforation 14. The example relates to colour stripes in a white base soap, and the base soap may also be of non-white colour, or transparent.

Abstract: 856,758. Operating four-stroke engines; intake passages; combustion chambers. TEXACO DEVELOPMENT CORPORATION. Nov. 29, 1957, No. 37263/57. Classes 7(2) and 7(3). Throttling of an induced air intake passage 17 by a valve shroud 31, which causes tangential swirling of the cylinder air charge at a rate of about six revolutions per crank-shaft revolution, is compensated for by an internally smooth air intake pipe 33 of such length and internal diameter as to effect inertia supercharging of a dynamic transient nature. The inlet valve 19 opens at the beginning of the suction stroke and closes just after its end. For an engine with a fuel-air ratio of 0.06 : 1 and whose piston bore and stroke are respectively 3¢ inch and 3¥ inch and the air swirl rate of which is 4.4 revolutions per crank-shaft revolution, a pipe 33 of 18 inch length and 1 # inch internal diameter is used, but reference is made to pipes of lengths of from 12 inch to 30 inch and internal diameters between 1“ inch and 1¢ inch. There is an exhaust valve 23. The cylinder head or cylinder wall mount a spark plug 27, 0 degrees to 120 degrees downstream in the swirl direction from a nozzle 29 which initiates fuel injection about 75 degrees to 20 degrees before T.D.C. on the compression stroke for non-knocking combustion on a stationary flame front as in Specification 596,846. In addition to the use of the shroud 31, the inlet valve port may be of reduced area to increase inlet air velocity and therefore swirl rate, and it may be inclined tangentially to the cylinder space.

Abstract: 1350191 Feeding ironing machines J H OELKERS 17 Aug 1972 [19 Aug 1971] 38440/72 Heading D1A In a laundry article storage and feeding device comprising a retaining web 15 of sheet material which is arranged to be wound between top and bottom drums 14 and 13, the articles are placed on the web 15 and wound onto the top drum 14 for storage and are wound off the top drum for delivery. When storing articles the bottom drum 13 is driven from a motor 18 without slip and the top drum 14 through a slipping clutch (29). To deliver articles the web 15 is urged by two rollers 45, 46 mounted on a pivotable frame against a roller 40 which is driven by engagement with a feed belt 17 of an ironing machine. This unwinds the web which passes over the rollers 45 and 46 and a further roller 47 on adjustable arms 49 and delivers the articles onto the upper run of the feed belt 17. The upper drum 14 is rotated by the web 15 and the lower drum 13 from the shaft 26 of the upper drum through a second slipping clutch (29), the two slipping clutches each being inoperative in one sense of rotation. A jack 65 to tip the apparatus about its wheels 11 is provided to facilitate engagement of the roller 40 with the feed belt 17. A pair of threads 55, 56 extending from drums (58), (59) (Fig. 2 not shown) drivable through slipping clutches (62), (63) pass round rollers on a frame 57 and the upper drum 14 to prevent articles from sticking to the underside of the web 15 on the drum 14 when being unwound. The frame 57 is raised when loading the apparatus when the motor 18 is controlled by a pedal 64 and lowered to deliver the articles. Articles are preferably overlapped on the drum 14 so that when passing from the feed belt 17 to the faster moving inlet of a ironing machine small gaps will remain between the articles.
