Abstract: Durable creases, pleats or other predetermined deformations are set in wool or other keratinous fibres in the form of slivers, yarn or woven, knitted or felted fabrics either in the piece or in the form of made up garments by treating the fibrous materials with a solution containing (1) a reducing compound, (2) a hydrogen-band breakdown reagent, i.e. urea, guanidine, a phenol or formic acid, or an anionic detergent and (3) a resin precondensate together with an accelerator which facilitates condensation of the precondensate and effecting the final setting part of the process by the application of moist heat with or without mechanical pressure.  The reducing compound (1) may be an alkali metal sulphite, bi sulphite, metabisulphite, or hypophosphite, thio glycollic acid or its ammonium or sodium salts, sodium hydrosulphite or one of its derivatives or formamidine sulphuric acid or a soluble salt thereof.  Suitable anionic detergents (2) are the sodium, ammonium, magnesium and calcium salts of an alkyl sulphuric, alkyl-sulphonic or alkyl arylsulphonic acid in which alkyl denotes a straight or branched hydrocarbon chain, preferably dodecyl, and aryl denotes a cyclic hydrocarbon ring, preferably benzene, and alkalimetal salts of alkyl carboxylic acids. The resin precondensate (3) may be a melamine-formaldehyde resin precondensate suitable accelerators for which are diammonium phosphate, magnesium chloride and zinc nitrate.  In the production of curled slivers or yarns the treating solution may be added to the rinsing water in the last bowl of the washing train, excess liquid removed and the damp material curled or otherwise deformed and heated in a steam autoclave at 120 DEG -125 DEG C. for 5-30 minutes. Alternatively after removal of excess liquid the material may be dried at a temperature not exceeding 50 DEG C. and subsequently curled or otherwise deformed after uniformly wetting and then heated. In the production of durable creases or pleats fabrics may be impregnated with the treating solution, dried at a temperature not exceeding 50 DEG C., made into garmets, e.g. trousers or skirts, arranged in creases or pleats, moistened and then pressed by means of a hand iron or Hoffman press.  Alternatively the impregnation with the treating solution may be affected after making the fabric into garments.  In the production of felt caps the pre-formed cap bodies made from felt may be impregnated with the solution, hydroextracted, pulled into shape on a former and heatset on the gas-heated metal former.

Title: Improvements in means for photographically recording acoustic vibrations
IPC: G11B7/003
Filed: 1931-07-28
Abstract: 378,191. Optical sound-recording apparatus. PULVERMACHER, K., 1, Parisi Utca, FREUND, P., 48, Benczur Utca, both in Budapest. July 28, 1931, No. 21584. Convention date, Aug. 13, 1930. [Class 40 (ii).] Consists in employing, in apparatus for making photographic sound records of the variable width type, a vibratory " light duct " formed as a transparent rod or a tube with smooth reflecting walls. The duct, which is fixed at one end and is adapted to be vibrated in accordance with the sound to be recorded, conducts a pencil of light from a source of light to a moving photographic film, a suitable lens system being provided. The direction of the light follows the vibrations of the duct, and a record is thus produced. The light duct may be vibrated by electrodynamic or electrostatic means, and two ducts having different natural frequencies may be used to make two records simultaneously on one film. In the apparatus shown in Fig. 3, the light duct consists of a glass rod 10 which is mounted at one end in rubber supports 12 in a casing 11. The rod passes through and is cemented to a cylinder 13 carrying two independent coils 14, 15, which lie in the fields of electromagnets 17, 16. Currents varying in accordance with the sound are supplied to the coil 15, while the coil 14 is short-circuited, for the purpose of damping, through a variable resistance 20. The coil former 13 is supported by means of a ring 22 surrounding it, the ring having flexible arms (not shown) fixed at their outer ends. Light is directed through the rod 10 by a condenser lens 24, and on emerging at the free end of the rod is focused by an adjustable lens system 26 upon a slit 27 past which a film 29 moves. When the rod 10 is at rest, one half of the length of the slit is illuminated, and a varying-width record is thus produced when the rod vibrates. Fig. 5 shows a modification in which the glass rod 10 is provided with a metallic coating 31 and lies between two electrodes 32, 33 connected to the secondary winding of a transformer 34. The electrodes 31, 32, 33 are connected as shown to a battery 35. Currents varying in accordance with the sound are applied to the primary winding of the transformer, and the rod is vibrated by the electrostatic forces thus produced. Two arrangements are described for producing two sound records simultaneously either side by side or on opposite margins of a kinematograph film, two light ducts of different lengths being employed in each case.
