Title: Improvements in apparatus for recording or reproducing cinematographic sound-films
IPC: G11B7/00
Filed: 1931-12-01
Abstract: 384,078. Optical sound recording or reproducing apparatus. ARCHER, C., Kinema House, Jeppe Street, Johannesburg, South Africa. Dec. 1, 1931, No. 33292. [Class 40 (ii).] Relates to optical soundfilm recording or reproducing apparatus wherein the film guiding surfaces at the sound gate are provided. with recesses disposed so as to register with the perforated portions of the film. In this way the film is able to lie flush upon the guiding surfaces despite any unevenness of the film surface caused by perforations which have become strained or torn. As shown in Fig. 1, the guiding surfaces 5, 6 of a sound gate slit-block 3 are formed with grooves 9 which register with the rows of perforations 7, 8 of the film 4. Fig. 2 illustrates the application of the invention in the case wherein the film 4 is guided over a hollow roller 10 adjacent to which is a fixed circular plate 11. Light projected through the sound track at 14 is reflected by a prism 13 in a casing 12 to the light-sensitive cell. Circumferential grooves 15, 16 are provided in the roller 10 and plate 11, respectively, to register with the perforations 7, 8 of the film. Specification 378,941 is referred to.

Abstract: 1399137 Hydrogen-carbon monoxide mixtures BRITISH PETROLEUM CO Ltd 8 Oct 1973 [17 July 1972] 33341/72 Heading C5E In a process for the production of a gas containing at least 94 volume per cent hydrogen and carbon monoxide by the partial oxidation of a C 1 -C 7  hydrocarbon fraction with an oxygencontaining gas, the heat supplied to the reaction is provided entirely by heating the reactants and the time between the contacting of the reactants and their entry into a bed of reforming catalyst is from 5 to 30 milliseconds. Mixing of the reactants before they enter the catalyst bed can be ensured by injecting them tangentially into an inlet chamber through a port which has a nozzle for the hydrocarbons projecting into the pipe for the oxygen-containing gas. The oxygen-containing gas, e.g. oxygen or air can be preheated to 700-1100‹ C. and the hydrocarbon feed, e.g. natural gas or coke oven gas, is not preheated to above 400‹C. The catalyst suitably comprises 3-15 wt. per cent nickel on an alumina, silica, alumino-silicate or magnesia support, which can also contain uranium, barium and/or potassium. The product gas has a temperature of 800-1200‹ C. and can be used for the reduction of iron ore in the upper part of a blast furnace or in a fluidized bed. As shown heaters 12 and 12a, which are alternately heated by combustion of fuel and air from lines 14 and 15, are used to heat the incoming air from line 21. The hydrocarbon feed from storage tank 1 and the preheated air are mixed in the swirl chamber 8 of the reformer 9 which contains a fixed or fluidized bed of the catalyst.

Title: Improvements in or relating to the manufacture of alkyd resins
Inventor: ARBUCKLE KENNETH HAROLD
IPC: C08G63/48
Filed: 1963-08-23
Abstract: An oil-modified alkyd resin capable of forming aqueous solutions is prepared by heating a polybasic carboxylic acid with a polyhydric alcohol which is at least trihydric and a drying oil to form a resin having an acid value below 20, then adding a different carboxylic acid having two carboxyl groups and one or more additional carboxyl groups and/or one or more ethylenic double bonds, and continuing esterification to give a final product having an acid value of 25-60. The resin may be dissolved in a mixture of water and an organic solvent miscible with both resin and water containing an alkali metal hydroxide, and in this composition may be dispersed pigments with or without extenders and other conventional paint additives, to give a coating composition.  The drying oil may be employed in the form of fatty acids or their partial polyhydric alcohol esters, and may be copolymerized, before, during, or after the esterification producing the resin, with copolymerizable monomers, e.g. styrene, vinyl toluene, or acrylic or methacrylic acid derivatives. The polyfunctional acid may be, e.g. trimellitic, maleic, fumaric, citric or itaconic acid. Suitable organic solvents are n- and iso-propyl alcohol, hexylene glycol, the monobutyl and monoethyl ethers of ethylene glycol and diethylene glycol and acetates thereof, the phenyl and benzyl ethers of ethylene glycol, diacetone alcohol and dimethoxy tetraglycol.  In examples a mixture of soya bean or linseed oil fatty acids with dehydrated castor oil fatty acids is copolymerized with styrene (in the presence of di-t-butyl peroxide), heated with pentaerythritol, phthalic anhydride and xylol until the acid value is 10-15, then heated with maleic anhydride and thinned with butyl cellosolve ("Cellosolve" is a Trade Mark). Enamels are prepared from these solutions by mixing them with TiO2 and LiOH in butyl cellosolve/water and adding a fumaric acid/ glycerol-modified rosin and cobalt naphthenate.

Title: Process for the polymerisation of olefines
IPC: C08F10/00
Filed: 1956-11-05
Abstract: Olefines are polymerized using as catalyst a salt of a Group IVa, Va or VIa metal and an organo-metal compound of an alkali, alkaline earth or earth metal or of zinc, in the presence of an inert diluent and characterized in that the reaction mixture is conveyed from the reaction zone to a heat exchange zone and back to the reaction zone in a continuous current and with the circulating current outside the reaction zone lacking a component necessary for the polymerization, e.g. the amount of monomer or of one of the catalyst components is regulated so that polymerization is complete at the outflow from the reaction zone or otherwise a second reaction zone is utilized wherein completion polymerization is ensured.  Optionally the circulating current is maintained in a state of laminar flow.  In examples ethylene is polymerized in a specified apparatus using a hydrogenated hydrocarbon fraction as diluent and titanium trichloride plus aluminium ethyl sesquichloride as catalyst and wherein the flow of ethylene is such that there is none present in the circulating current outside the reaction zone.  Specifications 799,392, 799,828, 801,031 and 853,310 are referred to.

Title: Electric pulse converting system

Filed: 1945-12-14
Abstract: 690,210. Pulse shaping and delaying circuits. STANDARD TELEPHONES & CABLES, Ltd. Dec. 14, 1945 [Oct. 2, 1944], No. 33904/45. Class 40 (vi). In a circuit for producing sharply defined pulses from pulses of relatively large width, the circuit is coupled to a source of pulsations, a resistor-capacitor filter, a diode and output circuit being connected across the source. A saw-tooth input wave, applied to normally non- conducting valve 1 causes anode current to flow at a point in the cycle determined by the cut-off bias, capacitor 6 being partially discharged. The resulting saw-tooth wave is applied to the resitor-capacitor combination 15, 16 in series with diode 17 and output resistor 18. Due to the discharge of capacitor 16 over resistor 15 between the peaks of the saw-tooth the diode 17 conducts just prior to a peak, a voltage pulse appearing across resistor 18. The occurrence of the output pulse relative to the input wave may be varied by adjusting bias potentiometer 5 and the width by varying resistor 15 and capacitor 16. The valve 1 may be omitted if the timing adjustment is not needed, broad pulses being applied over capacitor 14 to produce sharp output pulses, Fig. 2 (d) (not shown).
