Title: Improvements in means of obtaining diffused aluminium coated layers on metal articles
IPC: C23C10/30
Filed: 1957-06-13
Abstract: An aqueous coating composition for application to ferrous metals comprises aluminium or aluminium-alloy particles in a water vehicle with an inhibitor for preventing reaction between the aluminium and the water which consists of a fritted ground alkaline earth borate or alkali-alkaline earth borate.  The inhibitor may also comprise silicon oxide and aluminium fluoride. By "fritted" is meant melted and cooled.  The composition may also contain alumina or zirconia, and a suspending agent, e.g. clay.  Examples are given of preparing the inhibitor by melting together (1) barium oxide (or carbonate), boron oxide (or boric acid) and aluminium fluoride, and (2) sodium oxide (or carbonate), barium oxide (or carbonate), boron oxide (or boric acid) and silicon oxide (silica).

Abstract: 860,163. Filing paper sheets. CAKEBREAD Ltd., C. Jan. 2, 1958 [Jan. 2, 1957], No. 208/57. Class 146(1). Loose leaves are bound together between two opposed members 1, 2, the member 1 having thereon a binding post 3 which passes through holes in the leaves and the member 2, and the member 2 having resilient locking means which bite into the surface of the post when withdrawal of the post is attempted. As shown, the member 2 comprises three metal plates 4, 5, 6 secured together, the top plate 6 being dome-shaped at 8, and the plate 5 being recessed at 10, to accommodate a locking means comprising a spring steel strip 11. The strip 11 is slit to form two opposed resilient tongues 16, 17 which are notched to allow the post 3 to be forced therethrough; these tongues grip the post and bite into the surface thereof when an attempt is made to separate the two members 1, 2. In a modification, an outer dome-shaped plate on the member 2 covers the end of the post 3.

Title: Elimination of colour-forming impurities from 1,4-butanediol
Filed: 1953-01-05
Abstract: A process for treating technical 1,4-butanediol which is substantially free of unsaturated impurities which contains impurities developing a dark colour on treatment with concentrated hydrochloric acid, for removing such colour-forming materials therefrom substantially without decreasing its butanediol content, comprises treating an aqueous solution containing from 20 per cent to about 60 per cent by weight of said technical butanediol with hydrogen in the presence of a nickel-containing hydrogenation catalyst at a temperature in the range of 150 DEG  to 170 DEG  C. and a pressure in the range of 50 to 500 atmospheres for a time in the range of about 1 to 10 hours and recovering the 1,4-butanediol as a product which does not develop colour in 30 minutes after mixing with concentrated hydrochloric acid.  The starting material may be prepared by catalytic hydrogenation of butynediol obtained by reacting acetylene and formaldehyde.  In examples: mixtures of 1 : 4-butanediol with water are hydrogenated using a Raney nickel catalyst in an autoclave at elevated pressures (1); in similar processes Raney nickel and nickel, copper and manganese supported on a siliceous carrier are employed as catalysts (2); in a similar process a catalyst comprising nickel, copper and manganese supported on silica activated by heating in hydrogen is employed (3); 1,4-butanediol, prepared by hydrogenating at elevated temperature and pressure using the catalyst employed in (3), the 2-butyne-1,4-diol solution obtained by reacting acetylene and aqueous formaldehyde diluted with a recycle liquid, by passing the mixture downward over a copper, bismuth acetylide catalyst supported on granular silica gel at elevated temperature and pressure, is hydrogenated at higher temperature and pressure.

Dissolution is effected at 35 DEG  to 40 DEG  C. and crystallisation at 5 DEG  to 30 DEG  C. An organic solvent may be present in the crude product.ALSO:Crotonic acid is recovered from the crude product obtained by the oxidation of crotonaldehyde, containing crotonic acid, isocrotonic acid, crotonic aldehyde, crotonic anhydride, an oxidation catalyst and oxidation by-products, by distilling the product to obtain a fraction containing crotonic acid, iso-crotonic acid and volatile colour-imparting impurities, dissolving a portion of the fraction in hot water to give a saturated solution, cooling the solution to precipitate crystals of pure crotonic acid, separating the crystals from the mother liquor, returning a portion of the mother liquor to the distillation step, saturating the balance of the mother liquor at an elevated temperature with a further portion of the fraction, after replacing by water the portion of the mother liquor which was returned to the distillation step, and then repeating the crystallising-separating-dissolving cycle.

Abstract: 980,395. Brazing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 2, 1964 [Jan. 4, 1963], No. 484/63. Heading B3R. [Also in Division G6] The stainless steel can of a nuclear fue<SP>1</SP> element (see Division G6) has a helically wound stainless steel wire brazed to it. In a first method, the stainless steel wire is coated with braze metal. The coating may be a 92% nickel, 8% phosphorous alloy deposited by a process known under its trade name as the Kanigen process; alternatively, the wire may be painted with a powdered slurry of nickelbased alloy. In second method (Fig. 4, not shown), one or two wires of braze metal are co-wound with the stainless steel wire, the braze metal being a silver-copper-palladium alloy. In a third method (Figs. 6, 7, not shown), after the stainless steel wire has been wound, a tape of braze material is placed over the stainless steel wire so as to cross each turn; the tape is formed by rolling a plastics bonded powdered nickel base alloy wire. Alternatively, the tape may be a powder suspension which is squeezed from a dispenser to deposit it on the wire/tube assembly. In all cases, the joint is formed by heating in a vacuum.

Abstract: 1280441 Horizon detector BARR & STROUD Ltd 29 Dec 1970 [6 Jan 1970] 695/70 Heading H4D [Also in Division G2] A horizon sensor comprises a double-sided mirror 11 oscillated about a horizontal axis 13 and a detector 12, an infra-red image received through lens 10 being scanned by mirror 11 and detector 12. The signal from the detector 12 is fed to a light source 14 which is energized when the discontinuity between the infra-red received from the sea and the sky is detected. The light from source 14, which may be a point source, is reflected from mirror 11 and through a lens 15 astigmatizing lens 16 to give a line image of the horizin. The sensor of Fig. 1 may be incorporated into a sectant to provide a horizon image in darkness. The mirror 11 may be one-sided, the light from source 14 being reflected from the same side of the mirror as the received infra-red radiation, a prism then being included between mirror 11 and lens 15 so that the resultant light is parallel to the radiation incident on lens 10. The mirror 11 may be replaced by a rotated multi-sided prism. In order that the horizon line image may be horizontal irrespective of the orientation of the sensor the lenses 15 and 16 may be pendulously mounted. The lens 16 may be dispensed with, a pendulously mounted diaphragm having spaced parallel slits then being provided at source 14, or a pendulously mounted strip light being used as source 14. The source 14 may be continuously energized, the detector 12 then controlling a shuttering arrangement. To correct for any time delay between detection of the horizon discontinuity and operation of the source 14 two light sources may be used to produce images above and below the true horizon, or the sensor may be arranged to produce these two images from one light source. A pendulously mounted graticule may be associated with the light source to provide the horizon line.

Fins or ribs are formed on a metal tube by a series of dies 1, 2 . . . 10, each having 24 forming discs 13 mounted to rotate freely in a disc holder comprising three parts, e.g. the inner annulus 15 having tongues 18, Fig. 2, not shown, and outer annuli 16, 17 which parts are located by screws 21. The series of dies are integrally assembled by the screws 21, the sets of forming discs increasing progressively in diameter and the forming edges being successively modified from die to die. Openpitch helical ribs may be formed by slight rotation of the work during its advance discs in successive dies being slightly circumferentially offset from those in the preceding die. In a modification each die comprises grooved rolls 20 for forming ribs on a tube. The rolls are staggered from die to die to eliminate flash, while the grooves 22 remain in the same relative positions in space.
