Patent GB-147585-A (GB)
Title: Manufacture of a textile material
IPC: D01D5/00
Filed: 1920-07-08
Abstract: Textile fibres, such as wool, hair, or other animal fibres, cotton, linen, or other vegetable fibres, are mixed with a cellulose solution adapted to be converted into artificial silk by treatment with water, acids, ammoniacal copper oxide, zinc chloride, or other suitable substances.  Artificial fibres may be mixed with a cellulose solution of different composition.  A solid mass is thus produced in which fibres are distributed.  The fibres may be added while the artificial silk is being formed.  The mixture may be allowed to dry in mass and may be reduced by cutting or otherwise to threads, bands, films, or non-coherent fibres which may be spun, or the mixture may be moulded into cord-shaped masses which may be comminuted to obtain fibres suitable for spinning.  The mixture may be forced through tubes and on being introduced into a fixing agent may be drawn out to form threads or films.  Bands or films may be formed by mechanical pressure and then treated with fixing agent and dried, the dry films, bands, and threads being reduced to spinning fibres by well-known comminuting methods, or the bands may be twisted direct.

Title: Process for reducing the content of vinyl chloride monomer in suspension polymers of vinyl chloride
IPC: C08F2/00
Filed: 1975-05-12
Abstract: 1499762 Removing vinyl chloride monomer from a vinyl chloride polymer CHEMISCHE WERKE HULS AG 12 May 1975 [27 June 1974 29 Aug 1974 (2)] 19767/75 Headings C3P and C3G A process for reducing the content of unpolymerized vinyl chloride monomer in a vinyl chloride suspension polymer is characterized in that steam at a temperature of 80-150 C. is passed through a vinyl chloride suspension polymer which is moist with water. The duration of the steam treatment may be from 5 seconds to 10 minutes. The water content of the polymer which is moist with water may be 15-35% by weight. The weight ratio of polymer moist with water to steam may be 50 : 2- 50 : 50 and the extracted vinyl chloride monomer may be recovered from the vapour from the steam treatment. The specific examples refer to the treatment of polyvinyl chloride and an ethylene-vinyl acetate copolymer grafted with vinyl chloride (Example 3). In the case of heterogeneous gas systems the treatment with the steam may be carried out by the polymer falling freely in a fall tower, by pneumatic conveying or by fluidizing. In the case of poured polymers the treatment may be carried out on a porous base, e.g. steaming in a container provided with a porous base. Alternative continuously operating equipment are porous conveyer belts and conveyer troughs, screw conveyers, rotary filters and belt filters. The preliminary dehydration of and removal of monomer may be carried out in the same equipment, e.g. rotary filters, belt filters and screentype centrifuges.

Abstract: 664,503. Time switches. YIEINEN, K. J. July 28, 1948. [July 28, 1947] No. 20143/48. Class 38 (v). [Also in Group XXXVIII] In a timing device for operating an electric contact at a predetermined series of times, a luminar time-mark carrier .4 is rotated at a uniform speed through the arms of a yoke 7, the carrier or yoke being arranged for limited displacement when bulges 11 formed on the carrier engage the yoke, the displacement serving to actuate the contact. 'The carrier is in the form of a thin disc of cardboard or metal carried by pegs 3 on a plate 2 rotating once in every 24 hours, and has a time scale extending over one week provided by a screw turn spiral 5 and radial lines 6 marked at hourly intervals. The bulges, shown in detail at 14 in Fig. 3, are formed by pricking the carrier with a pointed instrument, a ring 13 of felt or other soft material being provided on a panel 12 behind the carrier to facilitate this operation. One leg of a yoke has a feeler 8 spaced from the others by the thickness of disc 4, and the feeler is given a radial displacement so as to follow the spiral time scale by means of an arm 9 engaging a corresponding spiral groove 10 in the near side of plate 2. When a bulge enters between the legs of the yoke, the disc carries the yoke along in the direction of rotation through a distance limited by a stop at which point the bulge forces the legs apart, passes through and allows the yoke to return to its original position under the action of a spring. Alternatively, the yoke may be fixed and the plate 2 mounted for limited rotation on shaft 1 against a spring. In either case the displacement actuates the contact. A yoke having rigid legs may be employed to flatten out the bulges when they pass through. In alternative constructions the time-mark carrier may be a strip of paper moving in a straight path on rollers, and a stationary carrier may be employed with a moving yoke.

In an electrical resistance comparison device comprising a circuit having four arms, a first and a second resistor are respectively connectible in the first and second arms and the other two arms comprise a variable inductive ratio standard including a winding and a movable contact thereon, there being switches at the ends of the inductive standard so that in use, the first and second resistors are operated on steady D.C. and the inductive standard is supplied with a cyclically varying form of current. The inductive ratio standard shown for comparing an unknown resistance R x  with a standard resistance R s  comprises measuring windings 48, 49, 50 and 51, 52, 53, respectively connected through reversing switches 54, 55 and 56, 57 to R s  and R x  so that the flux in the core of the ratio standard is cyclic and of zero mean level, and slave magnetizing windings 41, 42 connected to R x  and R s  through reversing switches 68, 69 and 70, 71 are employed so that the measuring windings themselves do not carry any current which might impair the accuracy of the measurement. In use, with contacts 56, 57, 81, 82, 70, 71, 85 and 86 open, the resistances 43, 44 are varied to give a null reading on a detector 67 connected to a secondary 66 of a corebalancing transformer connected to the measuring windings, a null reading indicating that no current flows through the measuring windings 48, 49, 50. Similarly with contacts 54, 55, 68, 69, 79, 80, 83 and 84 open, resistances 45, 46 are varied for zero current in the windings 51, 52 and 53. Inductive ratio standards 73, 74, 75, 76, 77, 78 are interposed in the feed of the magnetizing windings to ensure that once a setting for the latter windings has been obtained by adjusting resistors 43, 44, 45 and 46, this setting will hold no matter how the measuring winding 51, 52, 53 is altered while obtaining a balance to determine R x . After setting the magnetizing winding, the winding 48, 49, 50 is adjusted to the known value of R s  and the reading of winding 51, 52, 53 required for balance gives a direct indication of the value of R x . The reversing switches 54, 55, 56 and 57 are controlled by relays.

Abstract: 775,338. Pleated paper. FRAM CORPORATION. July 13, 1955 [Feb. 11, 1955], No. 20282/55. Class 96. Paper P, which is preferably moist, is passed between rolls 17, 22 with ribs 23 which compress the paper to form grooves so that pleats Fare produced. The spacing apart of the rolls 17 and 22 may be adjusted at 45, 46 to accommodate different thicknesses of paper, and the upper roll may be adjusted so that its ribs 23 come mid-way between those of the lower roll. Alternatively the numbers and positions of the ribs may be changed. If the paper is to be used for filters, it may also be longitudinally corrugated either by the same rolls 17, 22, or by others. Pivoted plates 32, weighted at 36, trail against the pleated paper to retard it so that the pleats form as illustrated due to the tendency of the paper to bend after grooving by compression. The paper may contain a phonol-formaldehyde resin and may be dried and cured after pleating. For hard papers, each pleating- roll may be grooved to correspond with the ribs of the other roll, or they may have rubber insets. Upper bars 25 and side bars (not shown in Fig. 5) guide the pleated paper, which may be trimmed at its edges.
