Patent GB-566300-A (GB)
Title: Improvements in and relating to electric discharge devices
IPC: H01J61/067
Filed: 1943-04-16
Abstract: 566,300. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 16, 1943, No. 6140. Convention date, April 21, 1942. [Class 39 (i)] In a cold starting positive column discharge device having an envelope 15 containing an ionizable atmosphere, the electrode which functions as a cathode comprises a member 21 so fine as to be heated to effective emission by the discharge and a disc 22 electrically connected to member 21, mounted in front thereof and obstructing at least 50 per cent of the crosssection of the envelope where it is located. This disc 22 avoids any substantial sputtering from member 21 in starting and, if the disc is situated within the volume normally occupied by the Faraday dark space, this space is reduced in dimensions. The illuminating power of the device is thus increased. The disc 22 may be divided into two halves, each connected to an opposite end of member 21. This ensures that member 21 is heated during starting by current passing therethrough to a portion of disc 22, whereas there is also a portion of disc 22 in direct contact with the mains to function as an anode when the current alternates. Member 21 may be of 2.55 mil. tungsten wire and disc 22 may be of nickel 20 mils. thick. Both may be activated by refractory oxides. Specification 542,853 is referred to.

Title: Process of performing endothermic gas reactions
IPC: C07C2/76
Filed: 1930-02-26
Abstract: The pyrolysis of normally gaseous hydrocarbons, such as methane or other lower members of the paraffin series, olefines, &c. to form acetylene and/or other unsaturated hydrocarbons is carried out at high space velocities and temperature, and the necessary heat is largely supplied by a simultaneous and independent exothermic reaction in situ consisting of the formation of hydrochloric acid from hydrogen and chlorine.  Diluent gases may be added, e.g. coke-oven gas can be used in the process.  The reacting gases, containing more or less equivalent quantities of hydrogen and chlorine, are led separately into a long, narrow tube, preferably constricted at or just after the point where the gases meet to ensure thorough mixing.  The tube may be heated at this point, or the gases preheated, to start the reaction.

Patent GB-726697-A (GB)
Title: Improvements in or relating to variable speed transmissions
IPC: F16H47/08
Filed: 1953-03-10
Abstract: 726,697. Change-speed gear. BORG-WARNER CORPORATION. March 10, 1953 [March 13, 1952], No. 6562/53. Class 80 (2). A two-train planetary 3-speed and reverse gear, associated with a hydraulic torque-converter 14 of the overrun-reactor type, provides a fluid-drive low, a split-torque fluid-mechanical second, and, in one-to-one-high, a choice of all fluid, all mechanical or split-torque fluid-mechanical drive. Both trains are sun-ring, the front 37 having intermeshed, the rear 38 simple planets. In low ratio (2.375) the front train 37 acts alone, drive reaching its sun 39 through the torque-convertor, an outer additional shaft 17, and friction clutch 18, and issuing at its ring 40, permanently fast with the output shaft 11. The planet-carrier reacts on a one-way detent 21, or, when two-way drive is required, on a band-brake 20. In split-torque second (1.727) all reduction is still in the front train only, but now the clutch 18 and brake 20 are released, and a front clutch 13 engaged to drive through an innermost intermediate shaft 15 the rear ring 51. At the same time the rear sun 49 is driven through the torque-converter and additional shaft 17 to which the rear sun is permanently fast, thus locking the rear train for split-torque one-way drive of the common planet carrier of both trains. Reacting on the front sun 39, braked at 19, the planet-carrier drives at reduced speed the output front ring 40. The three alternative direct-drives are as follows. All-fluid is by engaging the clutch 18 and a rear clutch 16 to lock together respectively both suns 39, 49, and both rings 40, 51, thus locking the gear as a whole for one-to-one fluid drive. All mechanical is by engaging the clutches 13 and 16 to by-pass the torque converter and the entire gear through the intermediate shaft 15. Split-torque is by engaging clutches 13 and 18, so that the former drives the two suns from the torque-converter, and the latter drives the rear ring 51 mechanically, giving a locked one-to-one drive. Reverse (2.428), all fluid, is by engaging the brake 20 and rear clutch 16, the rear train acting alone with fluid-driven input sun 49, stationed carrier and output ring 51. Input and output driven pumps (Fig. 1, not shown) supply pressure fluid for engaging the clutches and brakes and for lubrication. The clutches 18, 20 are multi-plate, that 13 being single-plate, constructional details being in Fig. 1, not shown.

Abstract: 344,660. Ornamenting. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A. -(Assignees of Woerner, H. R. ; c/o Armstrong Cork Co., Lancaster, Pennsylvania, U.S.A.) March 3, 1930, No. 6971. Convention date, March 7, 1929. [Class 93.] Relates to the process described in Specification 319,655, [Class 100 (ii), Printing processes &c.], for the manufacture of surface-decorated materials such as floor coverings by applying a design in a non-drying masking material on to a base, applying a decorating material such as cellulose ester lacquer over the whole surface, and then removing the masking material and the overlying decorating material. The masking material consists of a filler and a vehicle of sufficiently low surface tension to permit the material to spread but of sufficient viscosity to hold the filler in suspension without stirring. The filler is preferably whiting, but barytes, lithopone, ochre, or the like may be used. The vehicle may be glycerine or glycol, which are of substantially correct viscosity, but an agent for reducing surface tension, such as soap solution, is necessary. In order to reduce cost, water may be employed as the vehicle, in which case a viscosityincreasing agent such as gum tragacanth, a deliquescent material for preventing drying, and an agent for correcting surface tension are added. According to examples, there are used mixtures of (1) whiting, glycerine, and a solution of an anhydrous soap such as sodium or potassium oleate or stearate; (2) whiting, water, potassium carbonate, gum tragacanth, and soap ; and (3) whiting, water, glycerine, potassium carbonate, dextrine, and soap. The Specification as open to inspection under Sect. 91 (3) (a) states also that clay may be used as a filler, and that a soap, referred to as " Pine Jell," is employed to reduce surface tension. This subject-matter does not appear in the Specification as accepted.
