Title: Process for the manufacture of three-dimensional textile articles
IPC: A41C5/00
Filed: 1976-04-13
Abstract: 1532467 Finishing fabrics L PAYEN & CIE 13 April 1976 [14 April 1975] 15142/76 Heading D1S A three-dimensional elastic textile article is manufactured from a woven fabric including an elastofibre yarn of an elastane or an elastodiene yarn, by tensioning the fabric in both warp and weft directions, the tensioning force applied in each direction being close to, but less than, the breaking tension in that direction; heating at least a portion of the fabric while in a stretched condition, in a differential manner, with heat varying in amount progressively from the centre to the periphery of the fabric with a maximum amount of heat being applied in the area where the least elasticity is desired and the minimum amount of heat being applied in the area where the greatest elasticity is desired; and terminating the tensioning forces and heating applied to the fabric to obtain the desired three dimensional article. Preferably, the elasticity of the fabric is substantially the same in each of the two directions in which it is tensioned. Heating is carried out by contact with a source of heat, e.g. a domestic iron, by radiation from an infra-red source, or by a source of high frequency or ultra-high frequency. Before shaping, the elasticity of the fabric may be developed by heat or the fabric may be used as it comes off the weaving or warp-knitting loom. Tensioning of the fabric in the two main directions may be effected by a frame having fabric-holding pins and adjustable in these diretcions or by feed rollers stretching the fabric longitudinally as it is stretched laterally by a tenter pin frame. In Ex. 1, taffeta-weave fabric comprises in both the warp and weft a lapped yarn having a spandex core and a polyamide lapping. Whilst the fabric is stretched, four concentric circles spaced at 10 centimetre intervals are traced on the fabric. Differential amounts of heat are applied to each circular zone with a maximum amount to the smallest diameter zone and a minimum amount to the largest diameter zone to form a cup. In Ex. 2, the process of Ex. 1 is repeated but tracing 10 concentric zones spaced at intervals of 10 centimetres. The invention is applicable to the manufacture of brassiere cups and of umbrella shells.

Title: Improvements relating to plastic materials and articles formed thereof
IPC: C08J7/06
Filed: 1939-05-23
Abstract: The surface hardening of plastic materials is increased by subjecting the plastic material to the action, at subatmospheric pressure, of a vapour of a vaporisable compound of silicon such as silicon tetrachloride.  The plastic is preferably degassed, before treatment, under reduced pressure and in the presence of a dehydrating agent such as phosphorus pentoxide.  The treated plastic may also be degassed.  The treated plastic is preferably immersed in water, such immersion not taking place, however, until about four days after the silicon treatment has taken place.  The treated plastic may also be allowed to age-harden.  The treatment is particularly appropriate to the surface-hardening of optical components such as lenses made of methyl methacrylate resins. Specification 502,978, [Group XXIII], is referred to.

Abstract: 1,189,142. Radio and tape playback unit. LEAR JET INDUSTRIES Inc. 5 April, 1967 [5 April, 1966], No. 15588/67. Heading G5R. In a combined radio and playback unit for magnetic tape cartridges, of the type described in Specification 1,122,652, the tape is stiffened at the tape head to improve the precision of the track changing meanism. The tape cartridge 110 is inserted in a tunnel 44 in the unit, which, to assist movement of the cartridge, is provided with a pair of fixed rollers 135, 136 on one side of the tunnel and a spring mounted roller 125 on the other side which cooperates with an inclining portion 130 of the cartridge wall to urge the cartridge towards the tape drive and transducing elements of the unit. The endless tape 115, in the cartridge 110, carrying eight recorded tracks, is drawn by capstan 72 and pinch roller 121 past contacts 145, guide 150 and head unit 65. The head unit includes a pair of heads for stereo operation and is mounted on an arm 165 pivoted to a wall 31 of the apparatus. Depending from the arm is a cam follower 175 which is urged by spring 180 into contact with the side surface of a star-shaped cam wheel 176 having two sets of four 45-degree sections each of the four having a different level with respect to the base of the apparatus. Each time a conductive patch on the tape actuates contacts 145 to indicate the end of a track, solenoid 110 is operated to rotate wheel 176 by 45 degrees thereby pivoting arm 165 to a position in which the heads scan the next set of tracks. The arm 165 is pivoted to the wall 36 via a bracket 168 which is itself pivoted to the wall via a single rivet 169. Tongues 173 extend upwardly from the bracket and can be engaged by a screwdriver to rotate the bracket about the rivet whereby the arm 165 and hence the head 65 are rotated to bring the heads into angular alignment with the tape tracks. The height of the heads relative to the tracks is initially adjusted by screw 178 which lifts cam 176. The guide 150 includes upper and lower portions 151, 152 which guide the tape in the vertical plane and a mid-portion 155 including a tape engaging radiused surface 156 which imparts a curve to the tape and stiffens it adjacent the head unit 65. The drive motor which is of the type described in Specification 1,160,129, is an inside-out arrangement with a rotating outer shell which acts as a flywheel and has the direct drive capstan 72 connected thereto. The motor end bearings are set in the base and cover of the apparatus. The output of the transducer heads is directly connected, Fig. 24 (not shown) to a pair of output amplifiers and the radio output is connected to the same amplifiers via a pair of impedances.
