Title: Softening fabrics
Inventor: PARSLOW MICHAEL WILLIAM
IPC: C11D17/00
Filed: 1983-02-08
Abstract: A method of treating fabrics comprises contacting the fabrics with an aqueous liquor having a pH less than about 7.5, such as between about 5.0 and about 7.0, the liquor containing a cationic fabric softener and lanolin. The liquor is formed by adding to water a composition containing the cationic fabric softener and the lanolin, the concentration of these components in the liquor preferably being from 50 ppm to 500 ppm. The lanolin may be replaced by lanolin-like material such as derivatives thereof or one or more of the active constituents of lanolin either extracted from other sources. Preferred ratios of cationic softener to lanolin are 20:1 to 1:20 by weight. A liquor to fabric ratio of less than 25:1 is preferred. The method generally leads to a deposition of cationic softener and lanolin of less than 0.5% by weight of the fabric.
Patent GB-2121057-A (GB)
Title: Irradiation of povidone and povidone-iodine
Inventor: BUNTING THOMAS G
IPC: A61L2/08
Filed: 1983-05-12
Abstract: Povidone is sterilized by irradiation in the presence of iodine and iodide ions. In particular solutions of povidone are sterilized by gamma-irradiating the povidone in the presence of iodine and iodide ions, which are present in an amount which prevents gelation at that dose of gamma radiation which would cause gelation in the absence of the iodine and iodide ions. The gamma irradiation of povidone may be effected in the presence of iodine with both iodide and iodate ions or as povidone-iodine in the presence of iodide and/or iodate ions. Sterilization thus effected by gamma radiation while preventing gelation of the povidone and degradation of the povidone-iodine.

Title: Dielectric Compositions
Inventor: WHEELER JENNIFER MARY
IPC: C04B35/497
Filed: 1984-03-05
Abstract: A dielectric composition, particularly suitable for the manufacture of ceramic capacitors, comprises lead magnesium niobate and lead zinc niobate. There may be added small amounts of one or more oxide additives chosen from silica, manganese dioxide, zinc oxide, nickel oxide, alumina, ceric oxide, lanthanum oxide and tungsten oxide, gallium oxide, titanium dioxide and lead oxide, or additives such as bismuth stannate. The compositions can be fired at temperatures between 900 and 1075 DEG C so that in the case of multilayer ceramic capacitors high silver content internal electrodes can be used. Higher dielectric constants, for example 9000 to 17600, of the fired ceramics than conventional ceramics are obtained, thus permitting capacitor device size reduction.

Title: Making disposable diapers etc
Inventor: CHAPMAN L RICHARD
IPC: A61F13/15
Filed: 1984-03-14
Abstract: In a continuous, high speed method for elasticizing articles such as disposable diapers, incontinent briefs, and the like by securing an elastically contractible element to a moving, interconnected web of said articles, said elastically contractible element causing the discrete articles cut from the web to shirr in a direction substantially perpendicular to the direction of web travel, prior to application and securement, the web 640 from which the elastically contractible elements are cut is laterally stretched while at an elevated temperature which is less than its crystalline melting temperature and allowed to cool to ambient temperature. This molecularly orients the elastomeric material and makes the web dimensionally heat unstable parallel to the direction of stretching. The elastically contractible element is cut at 628 from the web of the heat unstable elastomeric material so that the length of the element 650 coincides with the width of the heat unstable web. The elastically contractible element is applied to the moving web 13 of interconnected articles while in a substantially untensioned, molecularly oriented, dimensionally heat unstable condition so that the length of the element is aligned substantially perpendicular to the direction of travel of the web of interconnected articles. The discrete articles cut at 730 from the web are thereafter subjected to an external stimulus, such as heat 740 to cause the elastically contractible element to shrink and become dimensionally heat stable and elastic in a direction parallel to its length, thereby imparting shirring in a direction substantially perpendicular to the direction of web travel. <IMAGE>

Patent GB-850022-A (GB)
Abstract: 850,022. Flame-cutting apparatus. BRITISH OXYGEN CO. Ltd. Nov. 18, 1958 [Nov. 19, 1957], No. 36001/57. Class 75(1). [Also in Group XXIX] A cutting oxygen control unit for a flamecutting apparatus (not shown) is located between an on-off valve (not shown) and the flame-cutting nozzle and is actuated by the pressure of the cutting oxygen to provide a gradually increasing flow rate of the cutting oxygen after the on-off valve is opened. The unit prevents the sudden commencement of the flow of cutting oxygen and consequent spatter and bad piercing. The unit incorporates a lift valve 16 loaded to closed position by a spring 17 and adapted to be opened by a diaphragm 23. The cutting oxygen is fed through an inlet (not shown) to the chamber 15 below the valve and is led by a by-pass 21 to the diaphragm chamber 22. The by-pass includes a needle valve 27. When the on-off valve is opened the pressure on the diaphragm gradually increases to cause the diaphragm to open the valve 16 to allow the oxygen to pass to an outlet 25 leading to the cutting nozzle.
