Title: Improvements relating to plastic foam materials
IPC: C08J9/36
Filed: 1963-05-21
Abstract: A plastic foam material provided with a slidable surface is formed by coating the irregularities or projections on the surface at the cut end of the material with a coating agent which provides the projections with smoothness and stiffness while retaining their resilience, the coating material being then dried. The foam material may be of ester-or ether-polyurethane, polyester, polyamide, vinyls such as polyvinyl chloride, polyvinyl acetate, Vinylon (Trade Mark), viscose and rubber.  The coating agent may be a silicone resin or oil, an oil or wax of the paraffin series, or a mixture of a synthetic resin and a silicone material e.g. a grease agent, solution or emulsion, or a paste of starch, processed starch, casein, dextrin or animal glue, a cellulose derivative e.g. methyl or carboxymethyl cellulose, vinyl, acrylic or other synthetic resin e.g. vinyl acetate-vinyl alcohol copolymer, alkoxylized nylon e.g. N-methoxymethylized nylon, polyvinyl acetate, partially-saponified polyvinyl acetate, melamineformaldehyde, which forms the slidable surface.  The coating agent may contain a static eliminator.  The agent may be applied by spraying, endless belt, or reverse rolls. The coating may be applied on both sides of the foam.  The coated foam material may be laminated by means of a binding agent or by a thermosetting joint process to knitted, woven or unwoven cloth, synthetic resin sheets, leather or imitation leather, or a laminate of foam and cloth e.g. knitted nylon cloth, may be coated.
Patent GB-791471-A (GB)
Title: Apparatus for the manufacture of tubes from thermoplastic materials
IPC: B29C48/09
Filed: 1954-07-09
Abstract: <PICT:0791471/IV (a)/1> <PICT:0791471/IV (a)/2> In the manufacture of tubes by extruding a thermoplastic material through an annular orifice formed by an outer casing and a core, any elements which project into the annular passage, such as supports for the core, are locally heated.  This prevents streaks of reduced thickness or stability in the finished tube which might otherwise be formed by local cooling.  The heating may be by electrical resistance or by circulation of heated fluids.  It is preferred to introduce the thermoplastic material into the extrusion head at a temperature considerably higher than its softening point and to allow a decrease of temperature, e.g. by means of cooling fins, so that it leaves the nozzle at a temperature nearer its softening point.  As shown in Fig. 1, the extrusion nozzle consists of a core a carried by supports b from an outer casing c.  A heating system d is arranged near the supports b.  Alternatively the supports b may be made hollow and electric heating elements embedded therein.  In another example, Fig. 4, the outer casing is made in two parts c1 and c2 which are flanged and bolted together.  The supports b for the core a are carried by the upper half c1 and adjacent to the supports b an annular groove h is formed and electric heating elements i are embedded therein, the elements being retained in position by an insulating ring k clamped between the two flanges.  Suitable thermoplastic materials are polyethylene, polystyrene, polyvinyl chloride, polymeric chlorotrifluorethylene, superpolyamides or plasticized cellulose acetate.

Title: Improvements relating to shuttleless looms for weaving
IPC: D03J5/00
Filed: 1929-07-04
Abstract: 335,974. Shimwell, 0., and Gawsworth Patents, Ltd. July 4, 1929. Weft-inserters not carrying bobbins &c., looms with.-Relates to weft inserters of the type described in Specification 225,987, wherein the weft in a groove b is engaged by one or the other or two projecting parts c, d, and is thereby guided down one of two slits e, f to the underside of the shuttle, so as to be ironed thereby on to the warp threads. A portion of the underside of the weft inserter between the slits e, f is cut away or recessed at g to prevent ironing on the weft thread until it has been pulled straight by the welt inserter and until the portion of the weft inserter beyond the slits has passed over it. The weft is thereby caused to form a tight selvedge before being ironed on to the warp threads.

Title: Improvements in or relating to washing machines
IPC: D06F23/04
Filed: 1957-07-01
Abstract: 820,346. Washing-machines. BEUCLER, M. R. July 1, 1957 [July 6, 1956], No. 20628/57. Class 138 (2). [Also in Group XIII] A washing machine comprises an annular tank 5, spaced inner and outer shells 7 and 6 constituting a tub rotatably mounted in said tank, means for rotating the tub such as by an electric motor or by water jets, and a pump 23 to transfer water from tank 5 to the tub, which water escapes below ring 9 back to tank 5. Water in tank 5 may be heated by heater 36 and then pass down through flexible pipe 30 and pipe 52 into pump 23 driven by motor 39 through belt 54. The pump forces the water up into hollow pivot member 16 which is clamped to shells 6 and 7, is supported in bearings 26, 27, 28 and has on it a pulley 20 driven by belt 53 from motor 39. The washing liquid enters the space between the bases of shells 6 and 7 and some of it emerges through holes 44 to mix with the washing. The remainder of the liquid rises between shells 6 and 7 and emerges either through holes 43 to mix with the washing or it comes out of orifices 41, strikes cups 42 and helps to rotate the tub. The tub may be provided internally with bosses 45 or ribs 46 through which water issues and is directed to drive the clothes in the opposite direction to the rotation of the tub. Water escapes from the tub through suitable orifices provided in the lower side of ring 9 from which it passes through filter 11 and back into tank 5. The tub may also be rotated by stationary jet nozzles 49 which impinge on cups 48 attached to shell 6. The motor may have two windings so that the direction of rotation may be reversible and it may be constructed with a hollow central shaft to allow washing liquid to flow directly through the motor. By means of a four-way distributer valve lever it is possible to set the machine for washing, spin drying, rinsing or air drying, the latter being achieved by admitting air to the filtering, dehydrating or heating device 36 in the tank and allowing it to be sucked into the tub by centrifugal action.
