Patent GB-793190-A (GB)
Title: Improvements relating to the dyeing of textile materials
Inventor: KILBY WILLIAM
Filed: 1954-11-12
Abstract: In the continuous dyeing of textile materials by impregnation, e.g. passing, with aqueous vat or sulphur dyestuff liquor, the dyestuff, an alkali solvent for the dyestuff, water and thiourea dioxide (or a mixture of thiourea and an oxidizing agent) are brought together just prior to the impregnating operation, the impregnation is effected at a temperature not above 25 DEG  C. and the impregnated material is then heated to at least 70 DEG  C. to effect reduction of the dyestuff.  Specified oxidizing agents when a mixture of thiourea and an oxidizing agent is employed are hydrogen peroxide, sodium peroxide and sodium hypochlorite. Heating is effected by passing the material through steam, molten metal or hot oil or first through steam and then through molten metal.  A reaction accelerator, such as ammonium or alkali metal molybdates and vanadates, alkali metal tungstates and ceric sulphate, may be added to the impregnating liquor.  When using molten metal for heating, as described, for example, in Specifications 620,584 and 665,454, a reducing liquor may also float on the metal surface where the material enters.  The pad box may be cooled.  The process is applicable to the dyeing of textiles of cotton, rayon, nylon, polyesters and polyacrylonitrile.

Title: Improvements in, and relating to, electric arc fusion welding
IPC: B23K9/28
Filed: 1933-11-25
Abstract: 428,395. Holders for arc - welding electrodes. BRIDGE, J. H. L., 61, Masefield Avenue, Southall, Middlesex. Nov. 25, 1933, Nos. 32987 and 32988. [Class 39 (iii)] In an electrode holder for hand welding, the electrode is carried in a tube A and its end is secured to a member C provided with a projection passing through a slot in the tube and connected with a collar D, the whole being rotated about its longitudinal axis. The rotation is effected by gearing driven by a shaft E connected to a flexible driving shaft X passing through the handle Y of the apparatus. The electrode is fed along the tube A by moving a carriage T connected to the collar D. This is effected by a screw R rotated by differential gearing in a casing L actuated by the shaft E. The rotation of casing L is regulated by a brake controlled by a lever N adjustment of which will therefore vary the speed of screw R. The carriage T carries electric supply contact brushes which make electrical contact with the sleeve D and thence with the electrode. Cooling air may be driven into the holder through the covering of shaft X. Specifications 395,348, 404,503, and 428,396 are referred to.

Abstract: 405,433. Electrodeposition of metals. MARINO, Q., 11, Woodlands Road, and DARLINGTON WIRE MILLS, Ltd., Albert Hill, both in Darlington. Nov. 23, 1932, No. 33149. [Class 41.] Zinc, copper, aluminium, tin, cadmium, lead, antimony, nickel, chromium or cobalt or an alloy of these metals is deposited from an electrolyte prepared by dissolving the tartrate paratartrate or oxalate of the metal or metals in aqueous ammonia. A suitable proportion is 60-80 grms. of the metallic salt dissolved in 1 litre of ammonia solution of strength 70-80 grms. per litre. For a more rapid deposition, the electrolyte may contain 90 grms. of the metallic salt to 1 litre of ammonia solution of strength 110 grms. per litre. In the deposition of alloys, the anodes should be composed of an alloy of the metals in the same proportions as in the electrolyte. For coating with bronze, the electrolyte may contain 90 parts of copper to 1.0 parts of tin. The electrolyte is preferably maintained at 50-60‹ C. An alloy of copper, tin and zinc may be deposited. Iron or steel may be coated first with zinc or cadmium, and then with copper, chromium nickel or tin.

Filed: 1923-09-10
Abstract: 215,406. Karslake, H. J. Sept. 10, 1923. Making at predetermined times.-In apparatus of the type in which a gas or electric heater is put in action at a predetermined time by means of an alarm clock and put out of action when the water has boiled by the motion of a lever supporting the tea-pot, the water being automatically forced into the pot by steam pressure, the kettle e and tea-pot g are supported on stands on the ends of vertical rods k, h attached to opposite ends of a lever j. The winder of the alarm-clock a engages a fork which, in the form shown, opens a cock to admit gas to a burner d lighted by a pilot-jet r. When the water in the kettle e boils it is forced up a pipe f arranged as shown into the tea-pot g, which then sinks. A cock c is then actuated by the rod h through a chain to cut off the gas supply to the burner d and admit it to a lighting-jet p. The rod is locked on descending by a spring catch o and closes an electric circuit to ring an alarm. Specifications 22077/91, 7570/11, and 530/13 are referred to.
Patent GB-977726-A (GB)
Title: Catalytic hydrodeoxygenation process
IPC: C07C2/88
Filed: 1963-08-26
Abstract: Hydrocarbons containing aluminium compounds and oxygen-containing compounds are purified by first removing the aluminium compounds followed by catalytic hydrogenation. The hydrocarbon may for example be the solvent stripper overhead obtained by stripping the product of oxidizing an aluminium alkyl to the corresponding alkoxide in the presence of a hydrocarbon solvent, e.g. kerosine.  The aluminium contaminants are removed by distillation or by washing with dilute acid, e.g. 2-40% aqueous sulphuric acid.  Hydrogenation is then effected at 60-1000 DEG  F., above 200 p.s.i.g., 0.5-6 vol/vol/hour with 600-5,000 SCF of hydrogen per barrel over any hydrogenation catalyst, e.g. nickel-molybdena on alumina, cobalt-molybdena on alumina, iron oxide, barium-copper chromite, molybdenum disulphide on alumina, or nickel sulphide on alumina. The product may be distilled and used as refinery distillates or reused as diluents in organoaluminium chemistry.

Abstract: 521,565. Drawing-dies. HERBERT, Ltd., A., and PICKING, E. C. Nov. 22, 1938, No. 33898. [Class 83 (iv)] Sectional drawing-dies for polygonal work have the segments backed up by wedge shaped abutment members individually adjustable parallel to the axis of the die. Each die section is of quadrilateral form and has one side 26 part of which forms a side of the polygonal die opening, a side 27 in sliding contact with the face 26 of the adjacent section, a' side 28 engaging bolt 29 for locking the section in adjusted position and a fourth side which is inclined and bears on an inclined abutment surface 13. The sections are mounted within a body 11 formed with spaced recesses in which are slidingly keyed as at 14 abutment members 12 mainly of cylindrical form, but provided with flat abutment surfaces 13. A plate 15 is bolted to the body 11 and through it are screwed sleeves 17 surrounding studs 19 projecting outwardly from the members 12 which may be locked in adjusted position by means of nuts 18, 36. The inner face of a plate 15 rotatably supports by means of pins 22 and slots 23, a size adjusting member which carries studs 34 projecting into grooves 33 in the die sections and which has holes into which a tool may be inserted for adjusting the die opening.

Abstract: 369,245. Indiarubber springs. LORD, H. C., 361, West 5th Street, Erie, Pennsylvania, U.S.A. Nov. 13, 1930, No. 34163. Convention date, Nov. 18, 1929. [Class 108 (iii).] An elastic support for a vibrating element such as an engine is adapted to interpose comparatively small resistance to movements of limited range in various-directions transverse to one another, but to introduce high resistance to movements beyond the limited vibration range. The arm 19 of the engine of a motor vehicle is supported from the frame 23 by an annular rubber support 10 vulcanized to inner and outer sleeves 9, 11 preferably so as to be in radial tension. The outer sleeve is secured in the end of the arm 19 while the inner sleeve is mounted on a bolt 22 fixed to the frame 23. Small vibrational movements of the engine support 19 transversely of the bolt 22 are comparatively free, but larger movements are largely resisted when the collars 17 engage the thin layer of rubber at the upper and lower ends. The rubber sleeve 10 is so shaped in relation to the collars 17 that contact between the two occurs normally round their inner peripheries close to the sleeve 11. Small vertical vibrations thus take place freely, but larger vibrations upwards or downwards are abruptly checked when the clearance between the outer parts of the collars and the rubber is. taken up. Specification 297,315, [Class 108 (iii), Springs &c.], is referred to.
