Title: Improvements in or relating to means for suppressing arcs in electric switchgear
IPC: H01H71/40
Filed: 1952-03-27
Abstract: 710,386. Arc-rupturing in switches; air-blast switches; automatic circuit-breakers. HAIRY, R. E. March 27, 1952 [March 28, 1951; June 1, 1951; March 13, 1952], No. 7900/52. Class, 38(5) The active surfaces of the arc horns of a circuitbreaker consist wholly or in part of semi-conducting material, i.e. a material whose resistance decreases either when the applied voltage increases or the operating temperature increases. In one form, Fig. 1, an arc-suppression chamber 4 contains fixed contacts 9 and a movable contact 10, the arc-horns 5 comprising wires connected to the contacts 9, so that as the arc is moved up the horns by a coil (not shown) the resistance in series with the arc increases. The arc splitters 1 ... 3 are also of semi-conducting material. In a modification, Fig. 4, (not shown), the wires 5 are replaced by solid blocks of semi-conducting material connected to or integral with the contacts 9. In a further form, Fig. 7, the semi-conducting material comprises a pair of combs embedded in insulation 4, the ends of the teeth 15 being flush with the surface of the insulation so as to be engaged by the arc roots. The outer ends of the teeth are connected by strips 16 to the contacts 9. The movable contact 20 is hollow for the supply of an air blast. The invention may be applied to an automatic circuit-breaker, Fig. 10, having an arc-suppression chamber 26 in which a contact 30 is movable. The contact is connected to a lever 31 pivoted at 34 and having a roller 31a which is engaged by a recess 38a in a link 38 pivoted in a slot in a member 35 pivoted to a pushbutton. The parts are normally held in the closed position shown by a bimetal strip 50, downward deflection of which allows the member 35 to swing clockwise and permit counter-clockwise movement of lever 31 by a spring (not shown) so as to open the contacts. The latter may also be tripped by a coil 25 having an armature 40, a part 42 of which can disengage the recess 38a from roller 31a. Examples of suitable semi-conducting materials are given.

Title: Improvements in the production of coloured textile materials
IPC: D06P5/15
Filed: 1940-05-08
Abstract: 541,047. Dyeing textiles. BRITISH CELANESE, Ltd. May 8, 1940, No. 8257. Convention date, May 10, 1939. [Classes 2 (iii) and 15 (ii)] Pattern effects are obtained upon textile materials, especially such materials made of or containing a cellulose ester or ether, by discharging a ground colour thereon by means of thiourea dioxide or a substitution product thereof, e.g. a dioxide of an N-alkyl-; N-aryl- or N-aralkyl-thiourea. These may be used as such or in the form of their salts, e.g. their calcium, zinc or sodium salts, and other discharge agents, such as sulphoxylates, may also be present. In the application to cellulose ester or ether materials the discharge preparation advantageously contains one or more swelling agents for such materials such as thiocyanates, monoacetin, glycerol formal or thiodiglycol. The preparation may also be buffered by the addition of an acid, e.g. acetic, citric or tartaric acid, or of an alkaline salt, e.g. disodium phosphate or sodium acetate. Coloured discharges are obtainable by incorporating dyes resistant to the action of the thiourea dioxide, e.g. amino-, hydroxy- and mercapto-anthraquinones and their substitution products and vat dyes, e.g. of the Indanthrene series, which, when applied to a mixed material containing a cellulose ester or ether and natural or regenerated cellulose, are preferably used in their leuco form. Specified dischargeable ground colours are Setacyl direct discharge blue G, Setacyl direct yellow 5G, Setacyl direct orange GH, Setacyl direct red GN, Celliton discharge yellow 3GN or GRL, Celliton discharge blue 5G, Celliton discharge red BBL and the disazo dye, formed on the material, by coupling thereon diazotized 4-nitro-4<SP>1</SP>-amino- 3<SP>1</SP>-acetyl-amino-6-methoxy-azo-benzene or its 2-chloro derivative with 3-acetyl-amino- 1-di-(#-hydroxyethyl)-aminobenzene. In examples, (1) a fabric of cellulose acetate yarn, dyed with the dyestuff, 2:4-dinitro-6-chloroaniline#3-acetylamino-6 -methoxy-1-di-(#- hydroxyethyl)-aminobenzene is printed with an aqueous paste containing gum tragacanth, thiourea dioxide, monoacetin and disodium phosphate and the printed material is steamed for 5-20 minutes at 211-212‹ C. and washed to obtain a white pattern on a blue ground ; (2) the discharge paste in (1) is coloured with Indanthrene scarlet B and after the steaming the material is washed, scoured with neutral soap or a salt of an acid sulphate of a higher fatty alcohol and finally oxidized to obtain a scarlet pattern on a blue ground. Thiourea dioride is obtained by the action of hydrogen peroxide on thiourea.

Filed: 1948-03-22
Abstract: 636,158. Drawing. HUBBARD, N. F. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 22,1948, No. 8416. [Class 83 (iv)] A method of releasing tube gripping means after drawing comprises accelerating the drawbar 3, and the drawn tube 14 relative to the carriage 1 when the tube leaves the die 15, so that the drawbar, or an extension thereof 2, impacts against the carriage, whereupon the momentum of the tube causes it to over run the grippers and thus release itself. A helical spring 7, held in compression by the drawing resistance, extends when the tube leaves the die, and drives a head 5 of the drawbar extension 2 against the end of the recess 6 in the carriage. This momentarily halts the drawbar and the inertia of the tube carries the tube forward and releases the internallygripping segments 16 of the tube gripping means described in Specification 633,606. In modifications the means urging the drawbar and carriage into engagement with each other comprises pneumatic or hydraulic pistons and rams, an explosive charge, or a rubber cushion, and said means may be contained within the sections of a telescopic drawbar.

Title: Improvements in & connected with means for towing submersible objects
IPC: B63G8/00
Filed: 1924-04-05
Abstract: 235,981. Dartnall, H. J. April 5, 1924. Towing. - A submarine vessel is towed by a surface vessel, the depth of submergence being regulated by adjusting the fore-and-aft trim of the submarine, this adjustment being effected by altering the relative lengths of bridles connected to the towing-rope. In one form in which the submarine is manned by a crew who make the necessary adjustments of the bridles to regulate the depth of submergence, the bridles C, D, Fig. A, are connected to the drums of a winch located in a central control station provided with inter alia a conning tower and electric light apparatus which can be directed in various directions. The bridles after passing round the pulleys F, G, are connected up to the towing-rope A. The submarine, which is in cross-section of greater depth than breadth, is provided at its tail with a pair of fixed horizontal planes XVI and the action of the towing stream on these planes maintains the submarine at the required depth of submergence, whilst an ordinary vertically hinged rudder XV keeps the submarine at the required lateral distance from the vessel. In a modification, a crewless submarine substantially of the cross section shown in Fig. 3, is towed from a vessel by double towing ropes, C, D, which pass to barrels on a winch, and, by adjusting the relative lengths of the ropes, the towed object may be kept at the required depth of submergence or brought to the surface as required. The apparatus may be used for surveying wrecks.

Title: Process of treating wheaten flour or other vegetable flours or meals or the grains or seeds from which said flours or meals are derived
IPC: A21D2/02
Filed: 1937-03-31
Abstract: Ground materials, such as flour or the substances from which the ground materials are produced such as grain and legumes, are treated with activated carbon for the purpose of removing or preventing objectionable odours or flavours therein.  In a specific example, musty smelling wheat flour was treated with an addition of from ,0075 to ,01 per cent of activated carbon in the form of powder.  Fine grained activated carbons may be used and may be left in the flour. Carbons of a larger particle size and in larger quantities may be used and may be separated from the material after the treatment.  The process may be carried out by first mixing the carbon with a small quantity of the material to be treated, the mixture then being added to the main part of the material.  The mixture may be kept in motion during the treatment. Other substances can be added to the activated carbon to obtain a better distribution or to produce an additional effect, e.g. the addition of lime to facilitate the removal of husks.ALSO:Ground materials such as flour, or the substances from which the ground materials are produced such as grain and legumes, are treated with activated carbon for the purpose of removing or preventing objectionable odours or flavours therein.
