Abstract: 523,751. Colouring nickel and nickel alloys. MOND NICKEL CO., Ltd. Jan. 13, 1939, No. 1247. Convention date, June 14, 1938. [Classes 82 (i) and 82 (ii)] Adherent coloured oxide coatings are produced on nickel or on alloys in which nickel is the principal constituent by heating the nickel or alloy in an oxidizing atmosphere for a period of time dependent on the temperature, the composition, and the thickness of the material. Black coatings are formed on nickel-chromiumiron alloys, e.g., those containing 70-80 per cent. of nickel, 11-15 per cent. of chromium, and 5-10 per cent. of iron, by using a temperature range of 1850‹-2200‹F. and a heating period of 2 minutes to 1 minute; blue-black coatings on nickel-copper alloys, particularly those known under the Registered Trade Mark " Monel," by using a temperature range of 1550‹-1900‹F. and a heating period of 3 minutes to ¢ minute; brown coatings on nickel of 98 per cent. or greater purity and containing not more than 1 per cent. of manganese by using a temperature range of 1500‹-1800‹F. and a heating period of 3 minutes to 1 minute; and blue-black coatings on nickel alloyed with 2-5 per cent. of manganese by using a temperature range of 1700‹-1850‹F. and a heating period of 4 minutes to 1 minute. The nickel or nickel alloy is preferably pickled immediately before heating, e.g., in a hot solution of sulphuric acid and sodium nitrate. The coloured products may be used, for examole, for reflector pans for heating elements on electric ranges, burner bowls on gas ranges, sheathing for electric heating elements, laboratory oven ,linings, in the manufacture of railway carriage roofs, camera cases, clock hands, gauge pointers &c.

Jan. 14, 1930, No. 1307. [Class 99 (i).] The outlet 17 of a grease feeder 1 is connected to the receiving nipple 24 of a bearing by a clamping member 18 which is resiliently mounted on the outlet 17 and is adapted to engage the head of the said nipple and to be moved to draw the nipple and feeder outlet tightly together. The outer end of the member 18 has an opening 18a on its lower side, a reduced opening 18b at its outer end, and a spherical bearing face 18c within ; the head of the nipple 24 is spherical and the outlet 17 is formed with a spherical seat. The feeder may therefore be applied to the nipple from a plurality of angles in different planes. The locking movement of the member 18 is effected by a handle 23 mounted underneath the feeder through links 22, 19. The latter is fulcrumed at its upper end on a stud 20 and is formed with legs 19a which engage ears 18d on the member 18.

Abstract: 509,422. Fluid-actuated valves. WESTING- HOUSE BRAKE & SIGNAL CO.,' Ltd., and KERSHAW, A. G. Jan. 14, 1938, No. 1340. [Class 135] [Also in Group XXXIV] A valve 20 controlling admission of air from a chamber 7 through a port 18 in fluid-pressure brakes is opened by the pressure of the air in the chamber acting on a piston 22 against the action of a spring 31. The piston 22 works loosely in a liner 25, and is sealed in its end positions by gaskets 26 and 27. The valve 20 itself is carried by a supplementary piston 19 mounted in a bore in the main piston 22 and subject to a light spring 23. In the closed position of the valve the force of the main spring 31 is taken by the gasket 26, the light spring 23 only pressing the valve on its seating 21. In this way excessive pressure on the seating 21 is avoided.

Abstract: 836,134. Joining cathode-ray tube envelope parts. SIEMENS EDISON SWAN Ltd. Jan. 9, 1958 [Jan. 15, 1957], No. 1550/57. Class 56. A process of joining the screen closure member to the body portion of a cathode ray tube consists in heating the respective rims while they are rotated almost in contract, to a temperature at which the glass becomes electrically conductive and passing an electrical discharge through the heated glass at the joint by means of electrodes located in proximity to the rims and substantially equiangularly spaced around the longitudinal axis, the electrodes directing flames on to the joint and being connected each to a separate phase terminal of a polyphase supply so that the joint is uniformly heated by the current passed through the heated glass between the' phase arcs to the glass and a substantially balanced load is taken from the supply. As shown in Fig. 3 an apparatus for joining the screen closure member to the body portion of a glass envelope for a cathode ray tube comprises chucks 10 for holding and rotating the closure member and body portion in axial alignment, a stationary member 12 supporting co-axial with the chucks equiangularly positioned insulators 16 each carrying a hollow electrode 2 directed towards the location of the joint between the screen closure member and a body portion when supported within the chuck, pipes 14 for supplying burner gas to the electrodes whereby to produce flames for heating the joint, and also a battery of heating flames 13 preferably uniformly spaced around the longitudinal axis of the chuck, and a polyphase supply having phase terminals respectively connected to the electrodes whereby, when the glass at the joint has been heated to cause the glass to become electrically conductive, polyphase arcs can be produced between the electrodes and the glass by the flames to complete the welding of the joint between the closure member and body portion of the envelope. For sealing a closure member of non-circular configuration to a correspondingly shaped body portion of a cathode ray tube envelope, the insulators are each mounted on a link pivotally connected with the stationary member, the links being engaged by a cam rotatable with one of the chucks and shaped to the configuration of the closure member so that the electrodes are, by radial displacement, caused to follow the configuration of the joint. Specification 751,196 is referred to.

Title: Improvements in or relating to a process of recovering inositol and the product resulting therefrom
IPC: C07C35/16
Filed: 1950-01-24
Abstract: Crude aqueous solutions of inositol obtained by hydrolysis of phytates are refined by neutralizing the phytate hydrolysate with at least one alkaline substance from the group calcium oxide, hydroxide or lime-inositol complex to a pH from about 6 to about 7, removing the precipitate, further treating the phytate hydrolysate with at least one of the above alkaline substances to increase the pH to within about 8.5 to about 10, removing the precipitate, and crystallizing inositol from the filtrate.  The mother liquor from this final filtration may be treated with calcium oxide or hydroxide or mixtures thereof, preferably using at least one mol. per mol. of inositol present, to precipitate a lime-inositol complex.  This may be treated with an acid substance to liberate inositol and form an insoluble salt with the calcium, e.g. phosphoric acid or carbon dioxides or the lime inositol complex may be used as an alkaline reagent in the initial neutralization of the phytate hydrolysate.  In the examples there are exemplified various aspects of the invention.

Abstract: 1368730 Polyamide filaments AKZO NV 12 Jan 1973 [14 Jan 1972] 1836/73 Heading B5B [Also in Division C5] Thread-shaped articles are made by melting and spin-drawing polyamide containing at least 80 wt. per cent of nylon 6, the spun yet undrawn product being provided with a spin finish made up of an oil-in-water emulsion containing 0À1-6 wt. per cent of benzyl alcohol. In examples, nylon 6 and a nylon 6/nylon 66 mixture are spundrawn into yarns at 600 m./min. using a 3À7 draw ratio, and applying the spin finish prior to drawing by means of a kissing roll. The oil component of the finish is a mixture of butyl stearate, dioctyl sodium sulphosuccinate, polyethylene glycol monolaurate, oleyl acid phosphate and KOH. The benzyl alcohol accelerates the transformation of #-crystalline form to α- form during drawing. The resulting low #/α ratio imparts improved stability to heat-treatment.
