Title: Improvements in or relating to the dewaxing of oil
IPC: C10G73/06
Filed: 1935-03-30
Abstract: 1 : 3-Dichlor-2-methylpropane is prepared by chlorinating isobutane or a monochlor derivative thereof in which the chlorine atom is attached to a terminal carbon atom, and heating to produce a mixture of chlorinated butanes.  This mixture is then distilled to obtain a fraction boiling at about 136 DEG  C. and consisting of 1 : 3-dichlor-2-methylpropane.  Chlorination may be effected in the vapour phase as described in Specification 320,406, [Class 2 (iii)].ALSO:Petroleum oils are dewaxed by adding a solvent consisting of 1 : 3-dichlor - 2-methyl propane and chilling to separate the wax. The oil is preferably completely dissolved in the solvent at elevated temperature, e.g. 100 DEG  F., before chilling, and the precipitated wax which includes crystalline, amorphous and intermediate waxes is separated by filtration, centrifuging or settling.  The wax is then washed with the solvent.  The solvent is prepared by chlorinating isobutane or a monochlor derivative thereof in which the chlorine atom is attached to a terminal carbon atom, and heating to produce a mixture of chlorinated butanes.  The product is distilled to obtain a fraction boiling at about 136 DEG  C., consisting of 1 : 3-dichlor-2-methyl propane.

Abstract: 600,477. Aeroplanes. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. April 24, 1945, No. 10250. Convention date, June 1, 1944. [Class 4] In an aeroplane comprising winged elements pivoted together about a substantially longitudinal axis and capable of relative angular displacement against the action of resilient means, each element is so loaded and provided with landing gear that no bending movement exists at the pivot in normal flight or when the aeroplane is at rest on level ground. As shown, winged elements 1, 2, each comprising a fuselage and tail unit are pivotally interconnected about an axis X-X, and each wing is fitted with landing gear comprising hydraulically-coupled pairs of wheels 6, 8, 9, 10 and 5, 7, the latter two pairs of wheels being located outboard of the centres of gravity of the elements. The displacement of the elements about the pivot is resisted by deformable members 57 (see Figs. 3 and 4 (not shown)) and may be damped by a friction or hydraulic damper 61, see Fig. 5 (not shown). In a modification, Fig. 2b (not shown), a central fuselage carrying a steerable tail wheel is rigidly secured to one winged element adjacent the axis X-X, and each element is formed with a nacelle for accommodation of load. The Specification as open to inspection under Sect. 91 also describes a construction (see Figs. 3a and 3b (Cancelled) (not shown)) in which two outer winged elements 24, 25 are pivoted to a central element 23 about convergent axes X 1 -X 1 , and X 2 -X 2 . The elements 24, 25 are fitted with ailerons 35, 36 (see Fig. 4 (Cancelled) (not shown)) operable automatically to provide an aerodynamic restoring force if the elements are displaced upwardly or downwardly about their pivots. This subjectmatter does not appear in the Specification as accepted.

Abstract: 951,642. Developing electrostatic images. RADIO CORPORATION OF AMERICA. March 24, 1960 [April 13, 1959], No.10529/60. Heading G2H. A developer for electrostatic images comprises a dispersion of finely-divided electroscopic particles in a liquid dimethyl polysiloxane having a viscosity of between 0.6 and 3 centistokes, with which compatible insulating liquids may be mixed to an extent which does not appreciably affect the properties of the siloxane,the concentration of particles in the liquid being not greater than onefifth by weight of the developer. Examples of compatible insulating liquids are high flash naphthas, kerosene, and trichlorotrifluoroethane. The electroscopic particles which preferably are of diameter not greater than 74Á may be of one or more natural or synthetic waxes or resins of melting point below 200‹C. and may contain one or more colouring materials. Specified materials for the particles include thermoplastic resins comprising polymers of styrene, substituted styrene and its homologues, a synthetic octadecene amide wax, carnauba wax, microcrystalline petroleum wax, a solid thermoplastic silicone resin, and a polyvinyl chloride containing a small proportion of polyvinyl acetate while the colouring materials may be carbon black, various dyes insoluble in the dimethyl polysiloxane, and insulating or photoconductive zinc oxide. Dispersing agents such as calcium stearate and a hydrogenated tallow derivative of imidazoline may be included to assist in coating the pigment particles or ball-milling them with the waxes or resins so that they form the core of the developer particles. By using toner particles comprising photoconductive zinc oxide different colour images may be successively produced in superposition on a single electrophotographic surface. If non-photoconductive zinc oxide is used overprinting cannot be effected.

Title: Improvements in and relating to thermionic valves
Inventor: HARRIES JOHN HENRY OWEN
IPC: H01J21/02
Filed: 1954-04-01
Abstract: 795,146. Thermionic valves. GENERAL ELECTRIC CO. April 1, 1955 [April 12, 1954], No. 10716/54. Class 39(1). A multiple electrode structure for a thermionic valve consists of an integral combination of a cathode electrode 8, Fig. 1, and another electrode 4 for example a control grid, in the form of interconnected areas deposited on a common support 1. In one form the grid is deposited on the top of a number of ridges 2 standing up from the insulating or semi-conducting support 1 and connected at one end in the form of a comb, Fig. 2. A metal layer 7 covers the bottoms of the grooves between the ridges, where it is coated with thermionically emissive material, and also the sides of the support. The upright walls of the grooves, which may be undercut for focusing effect, Fig. 6 (not shown), are coated with a resistive layer 10 to prevent charging. The whole structure is mounted with anode 18, Fig. 4, to form a vacuum or gas-filled disc-sealed valve. The heater 22 may be inside the valve, Fig. 3 (not shown), outside in mere juxtaposition to the cathode, as shown, or wound around an external projection from support 1. The grid is connected to the centre disc 11 by spring contact. The support need not be ridged, the interleaved cathode set 8, Fig. 7, and grid set 6 being then in the same plane. In another form the support is a conductor 34, Fig. 8, on which rests an insulating member 2 carrying the grid 4, the cathode 8 being deposited in the spaces left. The member 2 may be comb-shaped or a plate with a number of spaced apertures, Fig. 12 (not shown). In a multiple valve two or more grids may be simultaneously supported, and the anodes may be mounted in the same way as the grids especially where there is a diode section. The insulating support may be glass or ceramic or an intermediate such as " Photo-Caram " and the grooves may be made by cutting or moulding or, in the latter case, by photo-etching permitting reduction in groove dimensions to the order of 1 mil. The coatings may be applied by stencilling, photo-printing or evaporation, and once deposited may be thickened electrolytically. The Provisional Specification gives further details of the photo-etching and photoprinting processes.
