Abstract: 1,085,482. Producing knitted stretch fabrics; coating and shrinking fabrics. SAMCOE HOLDING CORPORATION. Jan. 21, 1966 [Jan. 22, 1965], No. 2943/66. Headings D1L, D1P and D1S. Elastic stretch and restorability are imparted to knitted fabrics containing ordinary fibres, i.e. fibres other than special manufactured stretch yarns such as spandex, e.g. cotton, by impregnating the ordinary fibres of the fabric with a curable resin in liquid form, e.g. a methylol imidazolidone resin, compressively shrinking the impregnated fabric, and curing the resin in the fabric while it is in the compressively shrunk state. The fabric is optionally unraveled or de-knitted to produce elastically stretchable and restorable yarn which may then be made up with other fibres into knitted or woven fabrics. If the fabric is to be deknitted a tubular knit fabric is preferably treated. A heat-curable resin is preferably used and after impregnation the fabric may be adjusted to a proper moisture content preferably by drying and then steaming prior to compressive shrinking, the drying being effected at a temperature below the curing point of the resin. The resin composition may also contain fibre lubricants, catalysts and wetting agents. The fabric may be laterally distended to a predetermined, enlarged and uniform width prior to compressive shrinking if a two-way stretch fabric is desired. For special effects the compressive shrinking may be carried out to such an extent that pleats are imparted to the fabric. In Fig. 1 the knitted fabric 13 is passed from supply container 14 to impregnating bath 15 which contains three rollers 16, 17 arid 18 arranged in triangular configuration and forming among them a reservoir 19 of the impregnating resin solution, the rollers 16, 17 forming an entrance nip and the rollers 16, 18 forming an exit nip. The fabric is then dried in dryer 20, optionally stored and subjected to other processing operations, e.g. stitch line straightening, steamed in steamers 22 to impart a desired uniform moisture content to the fabric and passed to the compressive shrinking apparatus 21 in which it is fed to the shrinking zone at a first predetermined speed and controllably released from the zone at a second predetermined and substantially slower speed, which may include a pair of nip-forming rollers at least one of which is supplied with an interior heating medium in the form of steam or heated oil to impart a temporary set to the fabric and a confining shoe. Curing is effected in curing chamber 23.

Abstract: 736,114. Electric battery lamps. STERNAT, F. Feb. 4, 1953 [Feb. 8, 1952], No. 3172/53. Class 39 (2). In a battery lamp of the kind wherein the bulb, either with or without an associated lens or reflector, is mounted within a closely surrounding cylindrical casing which has its axis normal to the flat external surface of the lamp and is rotatable axially for switching purposes, the switching cylinder is located within a partly or wholly cylindrical recess which is provided in the body of the battery, and the internal surface of the recess is provided with contacts which co-operate with contact-making members on the switching cylinder. The construction is such that the usual case or container for the battery and switching cylinder is dispensed with. Fig. 1 shows a battery unit consisting of groups 3 ... 6 of cells which are assembled to form a flat structure with a recess 2 at its upper end to receive a carrier 16, Fig. 5, within which a switching cylinder 20 is rotatably mounted. The groups of battery elements are connected to contacts 7 to 14 arranged one behind the other in pairs in the semi-cylindrical surface 15 of the recess 2, and the rotary switching-cylinder 20 carries a pair of resilient surface contacts 25, 26 connected to the lamp bulb 21. Ribs 27, 28 arranged along a diameter at the rear of the switching cylinder facilitate operation of the cylinder. The groups of cells of the battery and their connections to the contacts 7-14 may be so arranged that the groups can be connected in parallel or in series by appropriate rotation of the switching cylinder. In a modification a flat battery unit of the general form shown in Fig. 1 and with similar contact arrangements, is provided with a wholly cylindrical aperture to receive directly a rotary cylinder which may be made of moulded plastic material into which a bulb and connections thereto are pressed or embedded, and a light-reflecting covering is applied to a concave recess containing the bulb. A glass lens is pressed into the body and covers the bulb. The extent of rotation of the moulded cylinder is limited by two spring- pressed plungers or stops projecting from spaced housings in the periphery of the cylinder into engagement with an arcuate slot in the adjacent bounding wall formed by the battery unit. The stops also serve to retain the rotary cylinder within the housing.
