Patent GB-1058311-A (GB)
Title: Production of metal oxides
IPC: C01B13/24
Filed: 1964-01-22
Abstract: <PICT:1058311/C1/1> In the preparation of metal, silicon or boron oxides by the vapour phase oxidation of the corresponding halides, a stream containing oxygen is projected substantially rectilinearly into a reaction zone with a greater linear velocity than a stream containing the halide vapour, and all of the products of reaction are withdrawn from the reaction zone in substantially the same linear direction as the oxygen stream is introduced.  The velocity difference is preferably such as to give a positive value greater than 50 (in sec.-1) for the expression (V0-VT)/d0, where V0 is the linear velocity of the stream containing oxygen, VT is the component of the linear velocity of the halide stream along the axis of oxygen flow and d0 is the diameter of the oxygen stream immediately prior to contact with the halide stream.  When an inert gas is interposed in known fashion between the oxygen and halide streams, the above expression is altered to (V0 + V1 - VT)/d0, where V1 is the linear velocity of inert gas stream.  V1 may be as great as V0 but is preferably less than half V0.  Metals specified are Al, Zn, Sb, Zr, Cr, Co, Be, Cd, Mo, V, Ni and Sn.  As shown the reactants with an intervening inert gas stream are fed to the reaction zone in parallel flow through a burner comprising concentric cylinders. The halide stream may, however, also be at an angle to the direction of the oxygen stream or even in counter-current thereto. The oxygen-containing stream may be the combustion product stream obtained by burning CO in excess oxygen, the temperature of the stream being above 1300 DEG  C. and allowing the use of a relatively cold halide stream.  Mixtures of halide may be used, in particular, in the preparation of silicon dioxide, 0.1 to 20 mole per cent of AlCl3 may be added to reaction zone through a further annular passage.  The oxygen stream may include additive group 1A, 1B, 2A or 2B metals or compounds thereof.  The walls of the reaction vessel may be cooled by flowing inert gas over them.

Abstract: 815,171. Suspension document carriers. STANDARD TELEPHONES & CABLES Ltd. Jan. 25, 1957 [Jan. 31, 1956], No. 2778/57. Class 146(1) A document carrier comprises a flat T- shaped sheet 1 of material of suitable rigidly folded to form two surfaces 2, 3 which are maintained against each other to hold an inserted document substantially by friction, the cross piece 4 of the T forming oppositely located projections by which the carrier can be supported on lateral guides or conveyers.

Transparent plastic material is used so that a document such as a cheque may remain in the carrier while automatically handled. A piece of magnetic tape may be stuck to the back surface 3 and printed with a code for use in automatic sorting machines.

Title: Improvements in or relating to electrostatic spray coating
IPC: B05B5/04
Filed: 1956-01-30
Abstract: <PICT:0830514/III/1> An apparatus for electrostatically spray coating an article comprises an atomizer 14, a conveyer for the article spaced from the atomizer, means for feeding liquid, e.g. paint, to the atomizer at a controlled rate for atomization therefrom as a fine spray in a pattern having a central portion devoid of spray particles, a high voltage source 26 for charging the particles and maintaining the article at a spray-attracting potential, and an axial shaft on the atomizer carrying an electrode 24 for forming two zones of spray-repelling potential, the zones being spaced on opposite sides of the spray axis ahead of the atomizer and in a single axial plane of the spray.  Paint is delivered at a controlled rate to a tube 21, 22 having a cut-away part 22a to allow paint to flow to the interior surface of a rotating bell-shaped member 17 having an edge 17a which acts to atomize the paint and project it outwardly and forwardly in an expanding circular spray.  The electrode 24 secured to the tube 22 and connected to the same high voltage terminal as the atomizer 17 serves to modify the spray pattern produced on the article both in plan view, e.g. by splitting it into two arcuate lobes, and in cross-section.  The electrode 24 may be angularly off-set from the vertical plane containing the axis 17x of the atomizer, e.g. to compensate for the tilting of the lobes due to the rotation of the atomizer.  Atomizers may be disposed side-by-side in pairs at each side of a conveyer for the articles and a downwardly-directed atomizer above the conveyer may be vertically reciprocated between adjacent articles.  All the atomizers may be controlled by suitable "triggering" circuits.  A potential of 100,000 volts, speed of atomizer rotation of 900 r.p.m., and a rate of paint discharge of 200 c.c. per minute are mentioned.  Specification 710,920 is referred to.
