Title: Process and apparatus for false twisting a narrow film or continuous fibrous material
IPC: D02G1/08
Filed: 1967-12-04
Abstract: 1,210,408. False twisting. TEIJIN Ltd. 4 Dec., 1967 [5 Dec., 1966; 7 Feb., 1967 (2); 14 April, 1967 (2); 2 May, 1967], No. 55097/67. Headings D1D and D1F. Continuous thin narrow film, ribbon, band, foil, or tube or continuous fibrous material consisting of a thermoplastic linear high polymer is false twisted by passing it between overlapping surfaces of the annular rotating bodies 13, 13' of the same diameter but rotating in opposite directions with their axes parallel, the film travelling along the chord bisecting the overlapping surfaces. The overlapping surfaces are preferably composed of a synthetic rubber and the bodies are positioned such that the distance between the centres O, O' of the bodies is not less than the internal diameter 2r of a body. Also the difference between the distance between the centres O, O' and the internal diameter 2r is not less than the width of the film 6 and not greater than twice that width. The film is preferably a crystallised film which has been drawn in its longitudinal direction only. The film may be passed through a heating zone before being passed between the overlapping surfaces to produce a bulky yarn. A cooling device may also be provided prior to the false twisting discs, or cooling water may be applied continuously onto the disc surfaces. Alternatively a fibrillated fibre can be prepared by passing a drawn film between the overlapping surfaces.

Abstract: 1368987 Flameproofing cellulosic textiles AMERICAN CYANAMID CO 29 Nov 1971 [27 May 1971 11 Nov 1971] 55225/71 Heading D1P [Also in Division C3] An aqueous flame retardant finish composition for cellulosic textile materials contains tetrakis (hydroxymethyl) phosphonium dihydrogen phosphate, tetrakis (hydroxymethyl) phosphonium carboxylate and urea and/or a urea formaldehyde condensate. The carboxylate may be derived from an acid having a Ka of 1.34x10<SP>-5</SP> or greater, e.g. acetic, glycolic, lactic, malic, formic, propionic, butyric, valeric, citric or oxalic. The molar ratio of dihydrogen phosphate to carboxylate may be in the range 10:90 to 75:25. The condensate may contain up to 3.6 moles of formaldehyde per mole of urea. The composition may further contain up to 0.5 mole free formaldehyde and up to 1 mole of melamine formaldehyde condensate, per mole of total phosphonium salts. The methylol melamine condensate may be di-, tri- or hexa-methylol melamine, and may be partially or completely alkylated e.g. methylated. The compositions may be applied to the textile as aqueous solutions by padding, dipping or spraying so as to leave 0.5-5% phosphine derived phosphorus, and 2-10% urea based on the weight of the textile. The material is dried at between 75‹C and 210‹C for a period of several minutes to 15 seconds, and cured at 125‹-225‹C for between 5 minutes and 1 minute. Drying and curing may be a single operation and may be effected in an oven with forced air circulation. The textile should contain at least 20% cellulosic fibres e.g. cotton, rayon, linen or jute, which may be blended with silk, wool, nylon, polyester or acrylic fibres. The dihydrogen phosphate/carboxylate mixture may be prepared by reacting tris (hydroxymethyl) phosphine, formaldehyde and a mixture of orthophosphoric and carboxylic acids in a molar ratio of I to at least 1, the molar ratio of orthophosphoric to carboxylic acids determining the ratio of phosphonium dihydrogen phosphate to phosphonium carboxylate in the final product. The product is diluted with water and urea and/or urea - formaldehyde condensate added as required.

Abstract: 1411237 Electro-photography XEROX CORP 18 Dec 1972 [27 Dec 1971] 58250/72 Heading G2H An electro-photographic gravure member 1 either has lands coated with a photo-conductive layer 4, or is entirely surfaced with photoconductive material, and has valleys 3 filled with a developing medium which is liquid during development and during transfer of a developed image to a copy sheet. If the gravure member has its lands coated with photo-conductive material the shadow areas of the imaged member retain a previously applied charge, the developing medium and exposed areas lose their charge and the surface of the developing medium is distorted by electrostatic forces in the shadow areas, so that a copy sheet receives developing medium from the shadow areas and, if the developing medium is pigmented, becomes a positive print. A gravure member  entirely surfaced with photo-conductive material, however, forms a distorted surface on the medium in its exposed areas, as the pigmented medium shields the photo-conductive material beneath it, and so does not lose its charge. This time the copy sheet receives a negative print. The developing medium may be solid during exposure, and be melted for development and transfer.

Title: A system for adjusting text sequences stored in a memory
IPC: G06K15/00
Filed: 1979-02-15
Abstract: A system for adjusting text sequences stored in a memory into text blocks having variable right margins. The detection of a code signal causes the system to enter a non-playout adjust mode. The operator is then prompted to enter a line count for the text block to be formatted. After the line count is entered, the system proceeds to adjust the number of lines of text equal to the line count to the predetermined formatting parameters. An interrupt of the adjust mode occurs upon the detection of the end of text, mode- measure codes in memory, special codes (e.g. stop, edit, error, page end), hyphenation requests, forced line overflow, or upon completion of the text block line count. The system presents to the operator visual indicators upon the occurrence of an interrupt sufficient to define the cause of the interrupt and the location in text where the interrupt occurred. During the interrupt, the operator may enter information into the system or play out codes from memory, and then enter a code signal that causes the system to continue in the non- playout adjust mode. <IMAGE>
