IPC: D06M15/273
Filed: 1967-06-01
Abstract: 1,189,501. Grafting textile materials; textile treating compositions. DEERING MILLIKEN RESEARCH CORP. 1 June, 1967 [4 Aug., 1966 (2)], No. 25279/67. Headings C3G and C3R. [Also in Division D1] Soil release and durable press characteristics are imparted to a textile material by applying thereto a textile resin and a textile resin catalyst, simultaneously or subsequently applying, as an emulsion, a copolymer having at least 10% by weight acidic groups calculated as acrylic acid and subjecting the textile material to textile resin curing conditions at a stage in the process subsequent to the application of the textile resin and catalyst. The copolymers may contain acrylic, maleic, fumaric, methacrylic, itaconic, crotonic, cinnamic acid or polymerizable sulphonic or phosphoric acids which may be copolymerized with ethyl, methyl, propyl, isopropyl, 2-hexyl or butyl acrylate, methyl or ethyl methacrylate, an alkyl fumarate, maleate, crotonate or cinnamate, vinyl halide, styrene, acrylonitrile, methyl styrene, chlorostyrene or butadiene, and may be in the form of their sodium, potassium, lithium or ammonium salts. After treatment with the textile resin, catalyst and copolymer the textile material may be dried at 225-300‹ F., optionally irradiated with high energy particle or ionizing radiation at a dosage of 1000 rads to 100 megarads and cured at 130-200‹ C. e.g. in hot air or steam. The treating compositions may also contain an ethylene oxide-alkylphenol condensate in which the alkyl group contains 3-14 carbon atoms and at least 3 moles of ethylene oxide per mole of alkyl phenol, a softener and a mixture of glycerol monostearate and polyethylene glycol monostearates. The textile resin may be a condensation product of formaldehyde with propylene urea, urea, melamine, ethylene urea dihydroxy ethylene urea, an alkyl carbamate, acrolein, acetone, formamide, acetamide, acrylamide, methacrylamide, acetylene diurea, N- ethyl triazone, N,N<SP>1</SP>-ethylene-bis triazone, N- methyl chloracetamide, uron or dihydroxy uron. The catalyst may be magnesium chloride, zinc nitrate or fluoroborate, monoethanolamine hydrochloride, 2-amino-2-methyl propanol nitrate, an alkali metal sulphite, sodium carbonate, silicate or phosphate, potassium carbonate, bicarbonate or phosphate, barium carbonate or lauryl trimethyl ammonium hydroxide or carbonate. After drying fabric may be made up into garments, e.g. slacks, pressed and creased prior to curing. Cotton, paper, linen, jute, flax, viscose rayon,cellulose acetate, polyester, polyamide, polypropylene or polyacrylonitrile fibres, filaments, yarns or woven, non-woven or knitted fabrics may be treated.

Title: Improvements in and relating to the stretching of twisted yarns
IPC: B65H59/10
Filed: 1953-09-14
Abstract: 753,232. Stretching yarns. BARMER MASCHINENFABRIK AKT.-GES. Sept. 14, 1953 [Sept. 15, 1952], No. 25375/53. Classes 120 (2) and 120 (3). In a method of stretching twisted yarn from a double twist twisting frame the yarn is, during its travel between the yarn balloon and the drawing-off apparatus, passed over a guide pin the position of which is adjustable to permit the path of the yarn to be varied. In the arrangement shown yarn 4 from a double twisting spindle (not shown) passes through a guide 3, around a fixed pin 6 and then around a pin 8 mounted on an arm 7 so as to be rotatable about the pin 6, over the drawing off rollers 10 and 11 to a winding-on spool (not shown). By varying the angular position of the pin 8 with respect to the pin 6 the tension on the yarn can be varied thereby varying the degree of stretch imposed on the yarn. The pins 6 and 8 may be provided with grooves of different diameters and 'widths and may be axially displaceable so as to permit the desired groove to be brought into line with the path of the yarn.

Title: Improvements in or relating to propellant compositions
Inventor: SCURLOCK ARCH CHILTON
IPC: C06B29/22
Filed: 1961-07-13
Abstract: A solid propellent composition comprises a solid oxidizer and finely-divided aluminium or magnesium dispersed in a solid rubbery gel comprising a homogeneous dispersion of polyvinyl chloride in a high boiling liquid organic plasticizer which dissolves the polyvinyl chloride readily only at elevated temperature; the plasticizer is a sebacate, phthalate, or adipate, or a glycol ester of a higher fatty acid.  Preferably the ratio of polyvinyl chloride to plasticizer is at least 2:3 by weight, the oxidizer is present in major proportion, and the finely divided metal in minor proportion. Suitable oxidizers are ammonium perchlorate, sodium perchlorate, potassium perchlorate, sodium nitrate, ammonium nitrate, hexanitroethane, and mannitol hexanitrate.  Various plasticizers are specified, dibutyl sebacate being preferred.  The propellants have increased specific impulse and burning rate and reduced pressure exponent as compared with propellents not containing finely divided metal. Moreover the presence of magnesium reduces the amount of hydrogen chloride in the combustion product.  Specification 853,320 is referred to.

Abstract: 1302581 Electrophotographic element RICOH KK 27 May 1970 [10 June 1969] 25506/70 Heading H1K An electrophotographic element comprises a conductive support having a photoconductive layer 10 to 60 Á thick comprising zinc oxide, a resin and a sensitizer, and a layer on the photoconductive layer 1 to 3 Á thick comprising an organic photoconductor and a sensitizer. The conductive support may be paper or Al whilst the resin for the first photoconductive layer may be acylic, and the sensitizer Rose Bengal. The organic photoconductor is preferably pulyvinylcarbazole, polyvinyltriphenylpyrazolin, polyvinylacridine or polyacenaphthylene sensitized by Crystal Violet, Nile Blue or Methylene Blue FZ. The organic photoconductive layer may contain polystyrene or a polycaronate and a plasticizer such as diphenyl chloride or a chlorinated fatty acid. The organic solvent for the application of the organic photoconductive layer partially dissolves the resin of the first photoconductive layer and thereby forms a strong bond between the two layers.

Title: Improvements relating to electric meters
IPC: G01R11/60
Filed: 1944-12-20
Abstract: 601,312. Supply meters. BOLUS, J. E. Dec. 20, 1944, No. 25585. [Class 37] A maximum demand meter is constructed so as to dispense with clockwork timing mechanism, improve the accuracy at low readings, and provide a larger scale. The driving motor comprises a shaded-pole electromagnet 11, Fig. 1, and a disc 12 fast with a shaft 13, which also carries a second disc 14 passing between the poles of a control electromagnet 15. The shaft 13 is connected through worm gearing 17 to a pointer 18 moving over a scale 19 and also, through bevel gearing 20, to a cam-shaped copper shading member 16. The electromagnet 15 is of the constantflux type, for example it may be a saturated core energized from the voltage of the circuit. At starting the shading member 16 is in such a position that the control motor 14, 15 applies substantially no torque to the shaft 13 and the torque of the driving motor 11, 12 turns the shaft 13 and moves the indicator 18. The shading device 16 is also moved with a time lag dependent on the gearing 20 until the torque of the control motor is equal to that of the driving motor. As these torques are in opposition the indicator 18 then takes up a stationary position. In a modification, Fig. 2, the driving.and control motors 11a, 15a, have discs 12a, 14a fast with a shaft 13a carrying a driving element of a gearing 17a driving a further gear 22 through which the shaft 21a of the pointer 18a is driven. This is fast with the slider 23 of a potentiometer 24 connected with the control motor 15a. The driving motor 1a has a primary winding 25 and a secondary winding 26 wound on the shunt magnet, the secondary winding 26 supplying a current, approximately in quadrature with the voltage, to series coils 27, 28 and their series resistance 29. The control motor 15a has a shunt coil 30 connected to the supply mains 31 and series coils 32, 33 energized through a compensator 34 and the potentiometer 24, which varies the torque of the control motor 15a until it balances that of the driving motor 11a. The compensator 34 comprises a three-limbed transformer 36, a resistance 37 and a rectifier 38. The primaries 39 and secondaries 40 of the transformer are wound on the outer limbs. A coil 41 on the centre limb is supplied from the rectifier 38, which is connected across the resistance 37. Adjustment of the slider 42 on the resistance 37 enables the supply to the series coils 32, 33 tu be so adjusted as to be independent of fluctuations of supply voltage.
