Abstract: Rubber antioxidants in the form of free-flowing granules comprise the powdered antioxidant with 0.05-3.5 per cent of its weight rubber latex solids as binder.  The rubber latex employed may be a dispersion of butadienestyrene copolymer, butadiene-acrylonitrile copolymer, or neoprene, or a dispersion made on emulsion polymerization of one or more butadienes-1,3, e.g. butadiene-1,3, 2-methyl butadiene-1,3, 2-chlorobutadiene-1,3, 2,3-dimethyl butadiene-1,3, and piperylene with one or more other polymerizable compounds capable of forming rubber copolymers with butadienes-1,3, e.g. styrene, vinyl naphthalene, acrylic acid, methyl acrylate, methyl methacrylate, acrylonitrile, methacrylonitrile, methacrylamide, methyl vinyl ether, methyl vinyl ketone, and vinylidene chloride.ALSO:Rubber antioxidants in the form of free-flowing granules comprise the powdered antioxidant with 0.05-3.5 per cent of its weight rubber latex solids as binder.

Abstract: 695,220. Heat treatment. METROPOLI TAN-VICKERS ELECTRICAL CO._, Ltd. Oct. 11, 1951 [Dec. 5, 1950], No. 29768/50. Class 72 In a process for continuous heattreatment of metal strip or the like by electric induction heating followed by quenching, the cold untreated strip is preheated by passing it in heat-exchange relationship with the hot strip before the latter is quenched. As shown, strip 1 is annealed by heating it in an induction coil 6 and passing it through a pipe 4 where it gives up heat to the untreated wire, the pipe 4 being of sufficient length to cool the strip to a temperature such that quenching in the bath 15 will not re-harden it. A neutral or reducing gas is fed into the pipe 4 through an inlet 19, or alternatively given off at the annealing temperature by a material with which the strip is coated, and drawn off at 3 by a suction fan 21. The strip is finally drawn through pinch-rolls 16 and 17 and wound on to a spool 18.

Abstract: 611,730. Photo-electric apparatus for indicating dew-points. CLIFFORD, G. E., and AIR CONTROL INSTALLATIONS, Ltd. Nov. 11, 1946, No. 29983/45. [Class 40 (iii)] [Also in Group XX] In a dew-point indicator, of the kind in which a light-beam falls on a photo-electric cell after reflection from a cooled mirror surface exposed to the atmosphere under test, the light beam is subjected to two such reflections. As shown, Fig. 1, the gas under test is admitted to casing 70 through inlet 71 and leaves through outlet 72. The trapezoidal shaped vessel 73, adapted to contain heating or cooling media, is provided with inlet and outlet connections 75 and external reflecting surfaces 74. In side-tube 76, a light beam from source 77 passes through focusing lens 78 and is reflected in turn from the surface 74, the auxiliary mirror 80 in sidetube 79 and the second reflecting surface 74, to the photo-electric cell 82 in side-tube 81. Thermometers 83, 84 measure the gas and dew point temperature respectively. The indicating circuit, Fig. 2, comprises the triode 52 which operates relay 55, subject to the control of the cell 82 connected between the grid 53 and cathode 51 in series with the battery 50. The triode is normally biassed to cut-off by adjustment of the resistor 54 when there is no deposition of dew in the surfaces 74. Two forms of the vessel 73 are described to permit the use of either ether or brine as the coolant and provision is made for raising the vessel temperature by the passage of a heated liquid through an internally mounted U-tube in the case where either is employed.

Title: An electromagnetic pressure gauge
Inventor: DUBSKY BORIVOJ
IPC: G01L9/16
Filed: 1958-09-19
Abstract: 860,214. Electric pressure transducers. VYZKUMNY A ZKUSEBNI LETECKY USTAV. Sept. 19, 1958, No. 30037/58. Class 40 (1). A pressure-gauge comprises two perpendicular windings associated with a ferromagnetic core which is twisted by the pressure so that the magnitude of the voltage induced in the one winding when the other is A.C.-energized is indicative of the amount of twist and therefore of the pressure. In one embodiment (Fig. 1) a solenoid coil 5 and toroidal coil 7 are wound on a hollow torsional body 4 surrounded by a flat helical tube 1 secured to the body 4 at each end. When a fluid-pressure is introduced into tube 1 it tends to uncoil, thereby twisting body 4, and producing a magnetic coupling between the perpendicular coils 5, 7. In a second embodiment (Fig. 2) a central torsional tube 9 is surrounded by a casing 10 with helical slots 11, the casing being mechanically attached to the tube at each end, but with an insulating washer 15 at one end. A series of longitudinal conductors 12 bridge the casing 10, and an A.C. voltage is applied at terminals 13 to flow up the tube 9 and down the parallel conductors 12, thus forming a toroidal winding on tube 9. A solenoid coil 16 is wound round the tube 9. The fluid pressure is introduced into the tube 9 which expands, causing casing 10 to twist, thereby twisting tube 9 and producing magnetic coupling between the two windings, the induced voltage in winding 16 being indicative of the pressure inside tube 9. In a modification, for measuring pressure changes, the tube 9 is a permanent magnet, and the induced voltage in coil 16 is proportional to the rate of change of pressure.

Title: Improvements in or relating to printing processes employed in colour photography
IPC: G03C5/56
Filed: 1929-10-03
Abstract: 340,605. Colour photography. SPENCER, D. A., 118, Fulham Road, South Kensington, and COLOUR PHOTOGRAPHS (BRITISH & FOREIGN), Ltd., Victoria Road, North Acton, both in London. Oct. 3, 1929, No. 30056. [Class 98 (ii).] In printing processes for colour photography, the intermediate or final support for a colloid layer forming or adapted to form a relief image by differential hardening comprises regenerated cellulose. The material known under the Registered Trade Mark " cellophane " may be used. For reducing the light screening effect of the dichromate sensitizer which tends to penetrate into the support if the latter is immersed in the sensitizing bath, the sensitized layer may be treated with reducing agents such as acidified ferrous sulphate or the sensitizing solution may be modified by the addition of cane sugar or sodium or potassium chloride or sulphate or chromic acid may be substituted for the potassium dichromate. When the invention is applied to the carbon or " carbro " printing processes, pigments such as lead chromate, which are capable of being dissolved and removed by chemical treatment are used, so that the depth of colour in the component images may be adjusted before they are finally assembled. The component colloid image layers may be assembled in superimposition on a single support of regenerated cellulose or they may be assembled with each layer on a separate support, accurate registration being obtained by local stretching of the supports. According to the Provisional Specification, sheets of cellulose acetate which have been superficially regenerated as described in Specification 337,868, [Class 98 (ii), Photographic processes &c.], may be used as supports. Specification 317,909, [Class 98 (ii), Photographic processes &c.], also is referred to.
