Title: Method for treating superpolyamidic threads and products obtained thereby
IPC: D02G1/02
Filed: 1948-04-21
Abstract: A polyamide yarn or thread having a permanent crimped or kinked form is obtained by highly twisting it, allowing free contraction of the twisted yarn with production of deformations, setting the yarn by heating so as to render the deformations permanent, back-twisting to a low state of twist, and then subjecting the yarn to a heating and swelling treatment so as to release internal stresses in the filaments of the yarn.  This final treatment produces further permanent deformations. Preferably, after highly twisting the yarn, it is placed on a yielding support and allowed to contract freely during a treatment with tepid water at 40 DEG  C. with formation of crimps and kinks. These deformations are made permanent by heating the yarn to a high temperature in a dry or moist medium, e.g. in boiling water or in steam at 120-130 DEG  C.  The yarn is then back-twisted.  The yarn as such or after being formed into a fabric, is subjected, while free from tension, to the action of a heated liquid or vapour which by releasing internal stresses produces further kinks and similar deformations.  This latter treatment may be combined with de-sizing or dyeing.  The yarn may initially have a twist of 200 turns per metre and it may be highly twisted to 400-5,000 turns per metre.  The highly twisted yarn may be wound on cardboard or rubber tubes or slotted or perforated elastic sleeves, or retractable reels, to allow shrinkage.  The yarn may be composed of a mixture of nylon filaments and other filaments and fibres, e.g. rubber threads and mineral fibres.  The treated yarn may be cut to staple fibre.  In an example, two nylon yarns are highly twisted separately, one to the right and the other to the left.  They are immersed in water at 40 DEG  C., and allowed to develop crimps and kinks.  They are dried at 50 DEG  C., and set by heating to 125 DEG C. in moist air.  They are back-twisted separately until both have a small left-hand twist.  The two yarns are then doubled together with a low right-hand twist.  The thread so formed is sized and woven and the fabric obtained is immersed in a dilute soda solution to release internal stresses in the filaments of the thread and develop further permanent kinks and crimps.

Abstract: 1,056,672. Television. VOIGTLNDER A.G. March 16, 1964 [March 15, 1963], No. 11111/64. Heading H4F. [Also in Division G3] A television camera has an objective lens of continuously variable focal length, adjustable remotely, and a diaphragm automatically adjustable under the control of a photo-cell receiving light through the lens. As described, light passing through an adjustable iris diaphragm and the compound objective lens of a television camera is partially reflected by a beam-splitting prism on to a photo-conductive cell 17 associated with printed circuits including transistors 18, 21, 22, 28, 29, so that when the mean light intensity has a desired value, Schmitt-trigger controlled relays 23, 30 are respectively de-energized and energized as shown to short-circuit the iris diaphragm adjusting motor 16. Deviation of the mean light intensity in one sense or the other from the desired value causes operation of relay 23 or 30 to run motor 16 in the appropriate direction to correct the deviation. Cam-operated limit switches 44, 45 control the transistor circuits to prevent excessive travel of motor 16, the drive from which also includes a slipping clutch as a further precaution against damage. Visual or aural indication of extreme operation may be provided. The voltage supply to the transistors is stabilized by a Zener diode. Constructional details of a removable objective lens mount which also houses the prism, photo-cell, transistors, motor, and diaphragm as well as further motors for remote control of focal length and focus are given. Application to the control of a cat's-eye-type diaphragm and the use of thermionic valve circuits are referred to.

Title: Process of casting and stretching film
IPC: B29C48/91
Filed: 1955-04-19
Abstract: Films of thermoplastic, film-forming, synthetic linear organic polymeric material are produced by casting the material in the form of a substantially symmetrical film having a tapered contour and longitudinally stretching the film over stretching rolls, the tapered contour of the film and the stretching conditions being such that the stretched film is of substantially uniform thickness from edge to edge.  The film is cast in such a manner that a transverse section across its full width is substantially symmetrical about the longitudinal axis of the film and that the central portion of a transverse section of the film is thicker than the edge portions. The width of each of these edge portions preferably constitutes at least 15 per cent, e.g. 15-20 per cent, of the total width of the film.  The minimum thickness at the edges may be 91-92 per cent of the maximum thickness of the film, which may be at least 10 mils. The film may be stretched longitudinally 2-4 times its original length and the temperature of the surfaces of the stretching rolls may be 80-90 DEG  C.  The film material is preferably polyethylene glycol terephthalate but may also be a polyamide, a polyvinylidene chloride or a polystyrene.  In an example a melt of amorphous polyethylene glycol terephthalate prepared as described in Specification 578,079, [Group IV], is extruded through an extrusion hopper, the lips of which are adjusted so as to form a tapered film having a width of 19.25 inches and a central thickness of 0.075 inch, the thickness of the film at its edges being 8-9 per cent less.  The extruded material is cast on to the surface of a positively driven quenching drum and is fed into a longitudinal stretching section composed of three groups of horizontal, parallel, chromium-plated polished rolls whose surfaces are maintained at 80-90 DEG  C.  The first group of five rolls is positively driven at a peripheral speed of 5.3 yards per minute and the third group of five rolls at 16 yards per minute, the intermediate group of nine rolls being idler rolls. The film is reduced in width by about 14 per cent. The film is finally transversely stretched in an enclosed tentering apparatus maintained at 95-100 DEG  C. to three times its original width.  A long list of applications of such polyethylene glycol terephthalate film is given.  Specification 461,236, [Group IV], and U.S.A. Specification 2,071,250 also are referred to.
