Patent GB-737806-A (GB)
Title: A process for dyeing cellulose-containing textile materials
IPC: D06P3/64
Filed: 1952-12-15
Abstract: In the dyeing of cellulose-containing textile materials with metallizable direct dyestuffs which form sparingly soluble metal complexes, metallization is effected in the absence of amines in a neutral to alkaline dyebath containing anions of a phosphoric acid containing at least two phosphorus atoms in the acid molecule by the addition to the bath, either at the beginning of the dyeing process or after the greater part of the dyestuff has been absorbed by the fibre, of an agent yielding nickel or copper.  The phosphoric anions are derived from alkali salts of an acid of the formula Hm+2PmO3m+1 in which m is a whole number greater than 1, e.g. tetra-sodium pyrophosphate.  Agents yielding nickel or copper may be the sulphates, but advantageously alkali-nickel polyphosphates or alkali-copper polyphosphates such as sodium-copper-tripolyphosphate and sodium-copper-hexametaphosphate may be employed.  The dyebath may also contain sodium sulphate, sodium carbonate, urea, saccharose and dextrin.  The dyeings may be after-treated with the reaction product of formaldehyde with cyanamide, dicyanamide, dicyandiamidine or melamine.  Numerous examples are given. Specification 737,803 is referred to.

Abstract: 891,836. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. Sept. 16, 1960 [Oct. 5, 1959], No. 31939/60. Class 51 (1). In combustion equipment for example of a gas-turbine engine, of the kind comprising a flame tube disposed within an outer air casing, the flame tube comprises sections which overlap each other so as to form cooling air passages therebetween, the passages being formed by corrugations around the edge of one tube section which are in contact with the edge of the other tube section. The passages each diverge circumferentially and converge radially in the direction of flow of the air stream. The flame tube shown comprises overlapping sections 46, each of which comprises a frusto-conical upstream portion 50 and a cylindrical downstream portion 48, the upstream edge of the portion 50 which overlaps the portion 48 of the adjacent upstream section being formed with corrugations comprising troughs 56 and crests 54. The troughs 56 are in contact with the outer surface of the portion 48 and are secured thereto by spot-welding at 60. The downstream edge of the portion 48 is formed with axially extending slots 70 to permit circumferential expansion and contraction. The troughs 56 are of arcuate shape so that the air inlet passages 62 formed between the two sections diverge circumferentially in the direction of air flow and at the same time converge radially in the direction of air flow as seen in Fig. 4, due to the frusto-conical shape of the upstream portion 50 of the downstream section. The flame tube has a dome 28 at its upstream end, the dome having perforations 78 for the flow of primary air therethrough, the air being guided by vanes 80.

Abstract: 665,826. Automatic gramophones. MILTON, A. J. April 8, 1948. [Dec. 4, 1947] No. 32044/47. Class 40 (ii). In a magazine gramophone, the starting position of the stylus on the record is set in a position according to one or other of two different sized records, by means of a cam plate 16, Fig. 3, which is swung backwards and forwards about the pivotal axis of the pick-up arm 5 by a cycling cam 7, and is coupled to the pick-up arm shaft by a segment plate 17a which is normally locked in one position relative to the cam plate 16 corresponding to a 10 inch record, Fig. 4, by a catch member 18a, 21, 22 which is released, when a 12 inch record falls to the record, by a lever 23, Fig. 6, to another position, Fig. 5, corresponding to a 12 inch record. The segment plate 17a is coupled by means of the spring loaded finger 30, Fig. 6, to the pick-up arm shaft only during record changing, i.e. when the cycling cam is lifting the pick-up arm 5 by means of the rod 15 and cam-operated lever 14. When the pick-up arm is relowered, horizontal movement is temporarily arrested by means of a finger 32, Figs. 5 and 6, on a lever 33 lifted by a cam surface on the cycling cam 7. During this period the cam plate 16 is moved clockwise through a small angle prior to the cam 7 stopping, so that the cam plate 16 may be relatched with the segment plate 17a, to the setting for a 10 inch record.

Abstract: 615,324. Two-stroke and four-stroke engines. TEXACO DEVELOPMENT CORPORATION, and STEVENS; A. H. (Texaco Development Corporation). Nov. 29, 1945, No. 32236. Addition to 596,846. [Classes 7 (ii) and 7 (iii)] A modification of the method of operating an internal-combustion engine according to the parent Specification, wherein knocking is eliminated by forming a combustible air-fuel vapour mixture in a localised zone of the combustion space and igniting the mixture promptly to prevent the vapour being disseminated more widely through the combustion space, consists in injecting the fuel during the compression stroke into the swirling air charge in a plurality of radially directed equally spaced jets, a sparking-plug being placed slightly downstream of each jet to ignite the mixture as soon as it is blown thereto, establishing flame fronts . which ignite the mixtures formed by continued injection. The air enters a domeshaped combustion chamber 10 in a tangential direction through a shrouded inlet valve 41, the swirling persisting during the compression stroke and blowing fuel injected in two downwardly inclined jets 46, 47 towards sparking- plugs 62. Each jet may consist of a single orifice or of a group of small orifices and the fuel supply from a cam-actuated pump may be heated by an electric coil. The movement of the piston during the compression stroke produces a slight swirl in a vertical plane in addition to the swirl in the horizontal plane produced during the admission stroke.

Filed: 1928-11-08
Abstract: 324,731. British-American Laundry Machinery Co., Ltd., and Russell, E. S. Nov. 8, 1928. Ironing - machines with rollers rotating against concave surfaces. - Relates to means for removing from goods being ironed in a multiroller machine the marks made by the stripping tapes or strings. The tapes &c. 9, 10, 11, provided on the rollers 1, 2, 3, are arranged so that those on any one of the rollers are staggered with respect to those on the other rollers so that the marks made on the articles as they pass under one roller are removed by their passage under a subsequent roller, whilst no tapes &c. are provided on the final roller 4. The first three rollers are padded with material sufficiently resilient that the tapes &c. sink into it rather than into the articles being ironed. The chests 5, 6, of the first two rollers are not heated to so high a temperature as are the chests 7, 8, of the last two rollers so that the starch in the goods is not completely "cooked" during their passage under the preliminary rollers, but is sufficiently cooked to enable the cooking to be completed by the final rollers. For this purpose a pressure reducing valve 25, Fig. 3, is inserted in the steam supply pipe to the chests of the preliminary rollers 1, 2, and delivers steam at a pressure not exceeding 20 lbs. per square inch and preferably at about 10 lbs. The chests of the final rollers 3, 4, are connected direct to the steam supply at a pressure up to 100 lbs. per square inch.
