Title: A new or improved method of rot proofing textile materials
Filed: 1945-06-01
Abstract: 599,443. Rot proofing textiles. STEVENSONS (DYERS), Ltd., PARTRIDGE, H. W., KEY, G. E., and STEVENSON, F. M. June 1, 1945, No. 13862. [Class 140] Textile materials are rot-proofed by forming in situ on or in them water insoluble copper and/or zinc salts of certain organic acids (namely, naphthenic acids and their derivatives, saturated and unsaturated carboxylic acids containing ten or more carbon atoms, and abietic acid as found in natural resin, by treating the materials with an aqueous solution containing the ammonium salt of the acid together with a complex ion consisting of copper and/or zinc in combination with ammonium, followed by removal of excess liquor and drying of the textile material. The solution may be prepared by adding excess ammonia to an aqueous solution of a soluble salt of copper and/or zinc, and mixing the solution thus obtained with an aqueous solution of an ammonium salt of the organic acid, or by dissolving a water insoluble copper and/or zinc. salt of the organic acid in an excess of an aqueous solution of ammonia. Pyridine may be added to the impregnating solution. Specified organic acids are stearic, palmitic and oleic. In examples : (1) naphthenic acid is dissolved in aqueous ammonia, mixed with aqueous copper sulphate containing ammonia and diluted with water containing pyridine. Cotton webbing is impregnated with this solution, squeezed between rollers and dried on steam-heated cylinders ; (2) as in (1) using aqueous zinc sulphate ; (3) as in (2) but adding caustic soda to the solution as it is diluted ; (4) as in (1) using oleic acid; (5) cotton webbing is impregnated with a solution containing copper naphthenate, ammonia, pyridine and water ; (6) as in (1) using stearic acid. A hank of cotton yarn is impregnated with this solution, hydroextracted, and dried. (7) Natural resin is dissolved in methylated spirits and aqueous ammonia added. The whole is mixed with aqueous copper sulphate containing ammonia and diluted with water containing pyridine. A hank of hemp cord is impregnated with this solution. Specification 552,447 is referred to.

Filed: 1944-07-26
Abstract: 592,498. Vapour burners. EATON MANUFACTURING CO. July 26, 1944, No. 14269. Convention date, Feb. 9. [Class 75 (i)] [Also in Group XXXVI] A thermoelectric generator comprises a number of thermocouple strips 45 supported by two walls 18. The inner junctions 20 are adjacent a row of burner tubes 24. The walls 18 extend downwardly to a burner 11 which comprises a distributing chamber 25 supporting the tubes 24 which are formed with side openings opposite the hot junctions of the thermocouples. Adjacent the chamber 25 is a vaporizing chamber 26 to which liquid fuel is supplied by a valvecontrolled tube 37, Fig. 4, and from which vapour passes through a valve 32 into a mixing chamber 27 which opens into the chamber 25. As shown in plan in Fig. 4, the chamber 27 is flared at one end 30 which is provided with an air inlet control shutter 31. The vaporizing chamber 26 is heated by fins 35 extending from the burner tubes and also by a flame from an opening 36 in the chamber 25. To start the burner valve 32 and the valve 40 controlling the flow of fuel from the tank 13 are opened to allow a small quantity of fuel to flow into the chamber 27 and through an opening 42 into a priming pan 43. The valve 32 is then closed and the fuel in the pan 43 ignited to heat the burner. The valve 32 is then opened and vapour passes into the chamber 27 where it becomes mixed with air drawn in through the flared end 30, the mixture passing to the burner tubes by way of the chamber 25. The fuel tank 13 is provided with an air pump and fuel and pressure gauges. The burner tubes may be made of stainless steel not less than a thirty-second of an inch thick, the burner openings being not greater than five sixty-fourths of an inch in diameter. The housing 54 is raised when the apparatus is in use to serve as a flue. The whole is mounted on a base 12, the fuel container 13 being at the side of the burner and generator and being provided with a carrying handle. Overheating of the top of the housing 54 is prevented by a baffle plate 57 which is pressed against the top of the housing by a strip 60 when the housing is closed.

Title: Improvements in or relating to flame cutting apparatus
IPC: B23K7/10
Filed: 1956-05-08
Abstract: 808,709. Cutting by fusion. GROVE VALVE & REGULATOR CO. May 8, 1956 [June 13, 1955], No. 14277/56. Class 83 (4). A flame cutting apparatus for cutting holes in metal valve bodies 74 such as those described in Specification 808,708 comprises a frame 10, 11 adapted to be adjustably seated upon one horizontal side 73 of the body and carrying a vertical shaft 38 supporting a flame cutting torch 23 mounted for rotation about the axis of the shaft. The frame carries flanged wheels 14, Fig. 2, mounted on screw threads 18 on shafts 12 which are rotated by handles 19 for moving the wheels 14 inwardly to clamp the frame on the valve body 74. The shaft 38 is fixed to a cross member 22 of the frame and has rotatably mounted thereon a hub 39, Fig. 8 (not shown), from which extends an arm 41 carrying segments 44, 46 with arcuate slots 49, 52. The torch 23 which makes vertical cuts is adjustably mounted, Fig. 5 (not shown), on the end of an arm 36 pivoted at 43 to the arm 41 and adjustably clamped at 51 in groove 52. A second burner 24 for bevelling the cut edges is adjustably mounted, Fig. 6 (not shown), on a second arm 37 pivoted at 42 to arm 41 and adjustably clamped at 48 in groove 49. Segment 44 is rigidly secured to arm 41 whereby the bevelling burner 24 moves in a circular path only. Segment 46, however, is pivotally mounted at 43 to arm 41 and has an extension 54 carrying a cam roller 57 adapted to co-operate with a cam 56 fixed to the shaft 38. The profile of the cam 56 thus determines the path taken by the cutting torch 23 which path may be elliptical to compensate for distortions due to heating and cooling of the valve body. Springs 61, 62 press the roller 57 into engagement with the cam. The hub 39 is rotated on the shaft 38 by an electric motor 67 and tooth gearing 68, 69. A lifting ring 71 enables the apparatus to be moved to and away from the valve body. In operation the cutting apparatus is located on the valve body to be cut by a pin 77 extending through the shaft 38 and is clamped thereon by the wheels 14. The torch 23 is then moved inwardly of the cutting circle by a setting cam 64, Fig. 1, and after igniting the torch the motor 67 is started and the cam 64 is turned to bring the torch into the correct cutting path then determined by the profile of cam 56. After cutting the upper side of the valve body, the torch 23 is lowered through the cut hole, Fig. 5 (not shown), to cut the lower side of the body. The bevelling torch 24 is then used to bevel the cut edges, Fig. 6 (not shown).
