Abstract: 1488994 Embossed floor covering WACKER-CHEMIE GmbH 30 Jan 1975 [31 Jan 1974] 4122/75 Heading B2E A process for the continuous manufacture of an embossed dirt-retaining sheet-like structure comprises continuously coating a mechanically foamed paste of a vinyl chloride polymer at a thickness of 2.5 to 8 mm onto one side of a continuous support, gelling or drying the resulting coating, subsequently embossing the coating by means of an embossing roller to a depth of 2 to 6mm to form a pattern consisting of a plurality of small geometric shapes and dividing the coated support into pieces of the desired size. The gelling or drying steps may be effected at 130 to 200‹C. The support may be coated on both sides or, alternatively, only one side may be so coated while the other may remain either uncoated or coated with a non-foamed, generally highly filled vinyl chloride polymer paste or rubber dispersion or with a mechanically foamed rubber dispersion. The vinyl chloride polymer may be the homopolymer or a copolymer for example with ethylene, propylene, butylene, vinyl fluoride, vinylidene chloride, vinyl acetate, vinyl propionate, vinyl ethyl hexanoate, vinyl laurate, acrylic acid, methacrylic acid, fumaric acid, maleic acid and itaconic acid and esters of these or acrylonitrile.

[Class 39 (i)] In operating cathode-ray tubes, more particularly for television or measuring purposes, an interfering magnetic field is neutralized by the provision of a compensating field. A cathode-ray tube 2, Fig. 2, comprises an apertured diaphragm 11, which carries a tube 12, and an anode 10. Magnetized steel tubular quadrants 8, e.g. of tungsten steel, are mounted on the neck in such manner that the field passes through the electron - optical system and are rotatable to adjust the direction of the field by means of a thumb-screw 16, pulley 15 and a cord. The quadrants may be secured together by non-magnetic material. The strength of the magnets should be at least equal to that of the interfering field, e.g. the earth's field. Quadrants 9 of permalloy are mounted on the quadrants 8 and are adapted to be rotated by a thumb-screw 18, pulley 17 and a cord to adjust the intensity of the compensating field. In another form, two electromagnets are mounted so as to be rotatable about the tube axis and are connected in series and through a variable resistance to a battery. In a further form, the compensating field is provided by a Gramme ring 23, Fig. 4, which is energized by a battery 22 through a variable resistance 21 and a commutator 24 provided with rotatable bushes 25.

Title: Modification of sulphuric acid electrolyte employed in the anodic treatment of aluminium and aluminium-rich alloys
Inventor: MAILLARD EDMUND FREDERICK
IPC: C25D21/16
Filed: 1951-02-21
Abstract: Sulphuric acid employed as the electrolyte in anodic oxidation treatment of aluminium articles is freed from dissolved aluminium by the addition of an alkali metal (including ammonium) sulphate to precipitate the double sulphate of aluminium and the alkali metal. Precipitation is effected by cooling to -5 DEG C to -10 DEG C, supercooling being avoided by stirring or seeding.  An excess of sulphate (for example 100 grams of ammonium sulphate per litre) may be added to the acid which decreases the solubility of the alum.  The addition of this quantity of sulphate cools the acid from for example 15-20 DEG C to 5 DEG C when the ammonium alum precipitates.  The supernatant acid is replenished, the sulphate concentration restored and the acid used again.  After further use the acid is cooled, the alum precipitated and the process repeated.  Iron manganese and silicon impurities are largely removed on precipitation and filtration.
Patent GB-687193-A (GB)
Title: Method for feeding yarn to a knitting machine, having a constant tension and/or output, and yarn feeder for the performance of this method
IPC: D04B15/48
Filed: 1948-02-13
Abstract: 687,193. Knitting-machines. ETABLISSEMENTS PORON. Feb. 13, 1948. [April 15, 1947] No. 4240/48. Class 74 (ii). [Also in Group XXIV] A yarn feeding device, for a knitting-machine, delivers yarn at a constant tension and coinprises a member around which the yarn is wound and which rotates at a peripheral speed faster than the linear speed of the yarns and means for varying the arc of contact of some of the turns of yarn with the rotating member. In one embodiment, yarn 30 makes several turns 31 around a rotating cylinder 2, some of the yarns passing over a member 19. A rod 15 is positioned adjacent the turns 31. When the yarn tension decreases, a weight 22 causes the member 19 to pivot about a point 23 and to move away from the cylinder 2. The turns of yarn on the member 19 are thereby brought into contact with the rod 15 and the driving force on the yarn is reduced to deliver yarn at constant tension. A cone shaped member 10 controlling the delivery of the yarn is positioned near the cylinder 2 and the yarns also pass round the cone. The yarns are guided on the cone by an adjustable guide 27. The cone may be grooved or stepped. In a second embodiment (Fig. 6) the cylinder is replaced by two cylinders 41, rotated in unison by gearing, the yarn passing from the first cylinder along grooves 47 in a fixed central block 49 positioned between the two cylinders 41, round the second cylinder, and on to a cone controlling the yarn delivery. In this embodiment, a member 52 and rods 51 correspond, respectively, to the member 19 and the rod 15 of the first embodiment. With either embodiment, a device (Fig. 7) that relieves the tension imposed on the yarn by the knitting- machine is positioned between the knitting- machine and the yarn feeding device. If the tension at 76 increases, an arm 73 is drawn down and an arm 69 rises causnig rollers 70, 71n to press the yarn between rollers 65-67. A clutch (Fig. 8) to separate the yarn feeding device from the driving shaft of the machine comprises a tooth 87, on a plate 79 on the driving shaft 77, that engages a tooth 84 on a member 80 sliding on the driven shaft 78. A lag may be caused in engagement and disengagement of the clutch by members 92, 83, which-engage a screw thread 82 on the outside of the member 80 and allow the member to be lowered or raised gradually.

Title: Improvements in copolymers
IPC: C08F22/28
Filed: 1949-02-17
Abstract: Copolymers are produced by heating, at from 25 DEG  to 140 DEG  C. in the presence of a catalyst, a tris-2-propenyl aconitate with a 2-propenyl alcohol from the class of allyl, 2-methallyl, 2-ethallyl, 2-chloroallyl, 2-chloromethylallyl, 2-hydroxymethallyl, crotyl, tiglyl and cinnamyl alcohols, in the proportions of at least one molar equivalent of the alcohol to one motor equivalent of the aconitate.  Suitable tris-2-propenyl aconitates are the esters of any of the above alcohols.  Specified catalysts are acetyl and benzoyl peroxides and tert.-butyl hydroperoxide.  The copolymers can be isolated by addition of a non-solvent, e.g. diethyl ether or n-hexane, and may be purified by dissolving in acetone and reprecipitating.  They may be moulded or cast or employed in solvents, such as xylene, as lacquers or impregnating and water-proofing compositions.  The unsaturated copolymers may be further polymerized to the infusible state by heating at 60-200 DEG C., particularly in the presence of a peroxide catalyst.  They may also be dissolved in copolymerizable compounds, e.g. benzyl, tolyl, methyl and allyl acrylates, butyl methacrylate, vinyl butyrate, diethyl and diallyl fumarates, and the resulting solutions totally polymerized.
