Title: Coating metals and other material with stable metal oxides
IPC: B05B7/18
Filed: 1953-08-07
Abstract: <PICT:0745257/III/1> Coatings of heat-stable metal oxides or mixtures of such metal oxides alone or combined with other materials to form heat-stable substantially wholly metal oxide mixtures are produced by feeding a rod of said oxide into a flame hot enough to melt it, atomizing the molten oxide with a blast of gas as it is melted, and spraying the atomized molten oxide on to the material to be coated, e.g. metal, graphite, ceramic or sintered oxide.  The rod of oxide to be spray coated may be formed by sintering.  As shown, a metal spray gun having a flexible shaft drive 14 from a motor 10 drives through two sets of worm gearing 20, 22 a pair of rubber-covered rollers 26, 27 which feed between them a sintered metal oxide rod 30.  The rod is melted by an oxy-acetylene flame supplied from hoses 32. 33 and the liquid oxide is atomized by an air blast from hose 31.  Prior to coating it is preferable to sandblast the receiving material especially if this is iron or steel. Molybdenum gas turbine blades may be coated by this method with stabilized zirconia containing 3 to 6 per cent lime as described in U.S.A.  Specification 2,535,526 to resist oxidation in use, and similarly refractory graphite parts for guided missiles and rockets may be coated with alumina, while moulded alumina articles may be rendered less porous by coating with alumina. Suitable oxides for use in the invention are those of aluminium, barium beryllium, calcium, cobalt, magnesium manganese, molybdenum, nickel, niobium, strontium, tantalum, thorium, tin, titanium, uranium, vanadium, zinc, zirconium and minerals comprising combinations of these oxides, such as the spinels including those of chromium and iron (except magnetite), with or without other oxides, such as of antimony as in lewisite and of lead as in uraninite, and miner proportions of other substances such as helium, rare earths as in thoriahite, and even silicon as in emery or halogens.ALSO:A moulded crucible of pure crystalline and/or amorphous alumina, optionally together with 1 per cent bentonite, is spray-coated with molten alumina to render it non-porous.ALSO:Mixtures of heat-stable oxides of aluminium, barium, beryllium, calcium, cobalt, magnesium, manganese, molybdenum, nickel, niobium, strontium, tantalum, thorium, tin, titanium, uranium, vanadium, zinc, and zirconium, especially as minerals, and one or more minerals containing one or more of said oxides with iron oxides such as chromite, ilmenite, and tantalite or even emery, are melted and spray-coated on to metals such as molybdenum, ceramics such as alumina, or graphite to provide wear-resistant, refractory surfaces.

Abstract: 824,253. Anodic etching of and electrodeposition of metals on titanium and its alloys. NAPIER & SON Ltd., D. July 16, 1956 [July 29, 1955], No. 21949/55. Class 41. A method of electro-plating titanium or titanium alloys includes the steps of anodically etching the part to be plated in a substantially non-aqueous solution of hydrofluoric acid and pure ethylene glycol, swilling with acetone or other non-aqueous solvent to remove the etching solution and applying a nickel strike by electro-plating. In an example a titanium part is immersed in an anodic etching bath of hydrofluoric acid and ethylene glycol, lead cathodes being used. Upon removal from the etching bath the part is immediately transferred into a swilling bath of acetone. The part is connected to the negative pole of a source of electrical supply while still in the swilling bath, and is then withdrawn from this bath and immediately immersed in an electro-plating bath containing a lead anode already connected to the positive pole of the electrical source and consisting of a solution of nickel-sulphate and sulphuric acid. Upon removal from this bath the part is immediately placed in a swilling bath of acetone; and thereafter the part may be electro-plated first with copper and then with silver from cyanide baths.

Title: Method and apparatus for optical alignment of industrial equipment
IPC: G01C5/00
Filed: 1970-05-08
Abstract: 1316137 Aligning machines CONTINENTAL OIL CO 8 May 1970 [29 May 1969 19 Jan 1970] 22263/70 Heading G1M In the plan view of Fig. 1 various machines are tested for alignment when they are cold or not running and are also tested when running or hot, the horizontal and vertical distances of the various points A-H from a datum line of sight 18 in the cold condition alongside or over the train of machinery being first determined. The machines are then run until hot, and the original distances of the points A-H from the original datum line 18 are compared with the new points and distances of A-H to give a new or "hot" datum line, the machines having moved slightly as shown shaded under the hot conditions. If this new line of sight 34 is within acceptable limits of misalignment then the positions of the machines may be regarded as satisfactory. A linear gauge for measuring the distances between the points A-H and the datum line comprises a shouldered metal rod 74, Fig. 6, having releasably secured in one end a tip 70 adapted to contact the special abutments (tooling balls) at the measuring points. The rod is fixed by a pin 108 to a channel shaped member or shaft 92 mounting a scale 106, a viewing box device 66 fixed by screws 132, 134, Fig. 5, to the channel, and a dual spirit level device 68. The viewing box, Fig. 5, comprises a pair of diverging plates 136, 138 scribed with a series of fine parallel lines and fixed to a C bracket 130 adjustable along the shaft 92. The box is lined up with the cross hairs of a line of sight instrument and the whole linear gauge 64 pivoted about its tooling ball until the parallel lines of the box extend parallel to the cross hairs. In this position the linear gauge extends at right angles to the reference line of sight. In Fig. 11 (not shown) a movable laser target takes the place of the viewing box and its position on the scale is determined micrometrically. The target is sensitive to a laser beam and gives its highest intensity reading when exactly centred on the beam so that the distances of A-H from the line of sight may be determined. In Fig. 12 magnetized legs 216, 218 of a dial gauge may be mounted on exposed motor shafting 234, 238, Fig. 11. A centre pin 222 mounting a tooling ball 224 is also provided so that when the legs are stood on the motor shaft the instrument as a whole may be rotated on the shaft until a gravity operated mercury weighted printer 228 reads the angle it is desired for the pin 222 to make with respect to a vertical plane through the axis of the shaft. This instrument may be used as an abutment for one end of a linear gauge 244 as already described so that the distance between a precise high point on the shafting and a line of sight 243 may be measured. In Fig. 8 the linear gauge is mounted on extensible legs 170 and an adjustable foot 186, and a stabilising arm 176 mounting a magnetic retainer 178 may be positioned at a selected position to support the head portion 76.
