Patent GB-474128-A (GB)
Title: Improvements in elastic fabric and method of making the same
IPC: D03D15/56
Filed: 1937-02-24
Abstract: 474,128. Elastic fabrics ; coated fabrics ; compound fabrics. INTERNATIONAL LATEX PROCESSES, Ltd. Feb. 24, 1937, No. 5518. Convention date, March 17, 1936. Addition to 448,669. [Class 140] The process of making elastic fabrics described in the parent Specification is modified by applying a rubber-containing substance to the knitted, woven, lace or pile fabric so as temporarily to secure it to a surface stretched under tension and, after allowing the surface to contract and condense the fabric, causing the rubber to assume properties which will maintain the fabric normally in a condensed condition. The rubber-containing fluid may be rubber solution or an aqueous dispersion of rubber such as latex with or without compounding or vulcanizing ingredients and in vulcanized or unvulcanized condition. It may be applied by spreading or spraying and rendered tacky by heating or application of a coagulant or by using a heat-sensitive latex. As shown in Fig. 1, a fabric F from a roll 10 is sprayed with latex at L and with a coagulant at C. A second coating may be applied at L<1>. The fabric is introduced between the stretched portions of an inner belt 11 to which it adheres, and an outer belt 15. The belts are stretched by passing over a drum 12 and drums 13, 16 which are driven at a slower surface speed than drum 12. Pinch rolls 14, 18, 18<1> may cooperate with drums 13, 16, 12 to prevent slipping. Contraction of the belts as they approach the top of drum 12 gradually condenses the fabric which is held in condensed condition by the belt 11. The rubber is set or vulcanized sufficiently to maintain this condition by heaters 19 and the fabric is stripped from the belt and wound on roll 20. In a modification, the inner elastic belt is omitted and the lower surface of the fabric is rendered tacky and is engaged between the drum and the outer belt. In a further modification shown in Fig. 2, the fabric F is sprayed on its lower face at 22, partially dried by a heater 23 and fan 24 and introduced between the stretched portions of belts 25, 26 passing over drums 27, 28, 29, 30. Adjacent runs of the belts are held together by adjustable rolls 36, and heavy non-elastic belts 32, 33 driven by drums 27, 29, 34, 35 rotating at the same surface speed are provided to support the elastic belts 32, 33. The belts may be of rubber or webbing preferably woven of elastic warps and non-elastic wefts so that no transverse contraction occurs on longitudinal stretching. Less than the entire area of the fabric may be condensed by applying the rubber at selected areas or by applying to portions of the elastic belt a substance which prevents the fabric from adhering. A two-way stretched fabric is produced by stretching a knitted fabric longitudinally to contract it transversely before condensing it. Two condensed fabrics may be united by an adhesive such as latex.

Title: Radio frequency transmission line arrangements incorporating gas discharge tubes
IPC: H01J17/04
Filed: 1953-03-03
Abstract: 750,308. High-frequency discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). March 3, 1953, No. 5831/53. Class 39 (1). A radio-frequency transmission line in which a length of transmission line conductor is replaced by the plasma of an electric discharge in a gaseous atmosphere comprises a dielectric envelope enclosing the said atmosphere inserted between two metallic portions of the said conductor and a photo-emissive or/and a photoconductive coating on the said envelope excited by the luminescence of the said plasma. The arrangement may be used as a radiofrequency switch by switching on and off the high-tension .source which produces the discharge. The photons emitted by the ionized gas are utilized to augment the number of free electrons by exciting the photo-emissive surface or/and to provide a conductive path by exciting the photo-conductive surface, thus increasing the efficiency of the radio-frequency conduction path. In the embodiment shown, a gaseous discharge tube 5 bridges a gap in the inner conductor 4 of a coaxial line 3, 4 transmitting radio-frequency energy from a source 1 to terminal equipment 2. The outside diameter of the discharge tube 5 is approximately the same as the inside diameter of the conductor 4 and the tube is provided at one end with a conductive coating 9 and at the other end with a metal cap anode 8 so that the tube can be telescoped into the ends 14 of the conductor 4 which may be of flexible thin-walled construction. The conductive coating 9 is capacitively coupled to a cup-shaped cathode 7 which is connected through a radio-frequency choke 11 to the negative terminal of a D.C. supply. The anode 8 is connected to the positive terminal of the same or a separate supply, or alternatively the cathode 7 and anode 8 may be connected to a source of low-frequency alternating current. The discharge tube 5 is filled with an inert gas such as neon, argon, krypton, helium or a mixture thereof and has on its inner surface a coating 10 which extends along the greater part of the length of the surface but terminates short of the cathode 7 and anode 8 and consists of a material such as sodium or potassium which emits photo-electrons when excited by light energy from the gas plasma. Alternatively the tube may be coated on its inner surface or on its inner and outer surfaces with a material such as selenium, the electric conductance of which is increased in response to light energy from the gas plasma, or the coating may consist of a combination of the two types of material.
