Title: A process for the production of finishing effects on cellulose textile materials
IPC: D06M15/423
Filed: 1952-08-15
Abstract: Natural or regenerated cellulose textiles are impregnated with an aqueous solution of a methylol compound of a monourein in the presence of an acid-reacting hardening catalyst, dried and if desired heated for a short time.  The monoureins are 4 : 5-derivatives of 2-keto-, thion- or imino-imidazolidines, and may be derived from glyoxal, diacetyl, benzil and other a ,b -dicarbonyl compounds. Those derived from glyoxal are of the general formula <FORM:0720387/IV (c)/1> in which X represents O, S or NH.  If desired, the methylol compounds of the monoureins may be produced on the fibres. Methylol compounds of urea, urethanes or melamine may be added during the impregnation.  There may also be added polyfunctional compounds having reactive hydrogen atoms such as glyoxal, amino-alcohols and diamines, textile finishing agents such as high molecular polyglycol ethers, polyvinyl pyrrolidone, polyacrylic acid and its derivatives, polyvinyl imidazole, saponification products of polyacrylonitrile or polyacrylic acid esters, polyvinyl alcohol, soluble starch, dextrine, cellulose esters or ethers, animal glue and amides obtained by the reaction of long-chain aliphatic carboxylic acids and amino alcohols.  After drying, preferably between 40 DEG  and 85 DEG  C., the treated textile may be calendered or embossed and finally heated preferably at from 110 DEG  to 140 DEG  C.  In an example (all parts by weight) 120 to 140 parts of the dimethylol-monourein of glyoxal are dissolved in 1000 parts of water and 20 to 25 parts of zinc chloride added.  A regenerated cellulose staple fibre fabric is impregnated with the solution, dried at 70 DEG  C. and heated at 120 DEG  C. for 5 minutes. Specification 720,386, [Group IV (a)], is referred to.ALSO:A composition for impregnating natural or regenerated cellulose textiles comprises an aqueous solution of a methylol compound of a monourein and a textile finishing agent such as polyvinyl pyrrolidone, polyacrylic acid and its derivatives, polyvinyl imidazole, polyvinyl alcohol or a saponification product of polyacrylonitrile or a polyacrylic acid ester (see Groups IV (c) and VIII).  Monoureins are 4 : 5-derivatives of 2-keto-, thion- or imino-imidazolidines, and may be derived from glyoxal, diacetyl, benzil and other a ,b -dicarbonyl compounds.

Title: Improvements in and relating to flexible tube pumps
Inventor: BOLTON JAMES FRANKLAND
IPC: F04B43/12
Filed: 1952-08-20
Abstract: 713,239. Flexible tube pumps. AMES CROSTA MILLS & CO., Ltd. Sept. 21, 1953 [Aug. 20, 1952], No. 20859/52. Class 110(2) Relates to pumps of the kind in which a flexible tube 26, through which the fluid is pumped, lies against an arcuate track 13 and is squeezed progressively from end to end of the track by one or more pressure members, such as rollers 21, revolving round an axis concentric with the track. According. to the invention the compression and recovery of the tube takes place in a sealed liquidfilled container; by this means the recovery of the flattened tube is largely independent of the resilient qualities of the material of which it is made. The container shown is bounded by the track 13, two side plates, and a slightly domed top 14, the latter being fitted with a cock 16 which can permit water or oil from a bottle 15 to pass into the container. The rollers 21 are mounted on studs 22 fitted to a disc 20 on a shaft 18. the studs being eccentrically arranged so that the radial positions of the rollers on the disc may be varied. The output of the pump may be varied by increasing or decreasing the volume of the fluid in the container, such adjustment serving to vary, in inverse proportion, the volume of the chamber occupied by the tube. This is effected by providing a container extension 28, Fig. 3, in the side wall 11, and by providing in the extension a piston 35 which can be adjusted by screw and nut mechanism 32, 34. the nut 32 of which is connected to a hand wheel 31.

Title: Improvements in or applicable to looms for weaving tufted pile fabrics
IPC: D03D39/06
Filed: 1924-03-31
Abstract: 240,400. Platt Bros. & Co., Ltd., and Austin, F. W. March 31, 1924. Creel-frame arrangements; pile-fabric looms.-The parts of the tube-frame carrying- chains 11 situated near the place 22 where the tube frames are received from the chains for insertion of tuft yarns in the fabric being woven and are afterwards returned to the chains are held stationary from time to time whilst the remaining parts of the chains are driven continuously, and to enable this to be done, the chains 11 are engaged by upper sprocket wheels 15 and are passed around lower sprocket wheels 10 on a shaft 9, which at times is driven intermittently and at other times is held stationary, by means of a starwheel and a peg wheel with a locking segment or ratchet mechanism. The shaft 9 carries upwardly - extending adjustable links 13 having blocks 131 forming bearings for the shaft 14 carrying the sprocket wheels 15, which are engaged by the chains at two places as shown, and are turned thereby. Equal parts of the chains are thereby caused to approach and recede at these places. Square projections on the bearing blocks 131 fit in corresponding sockets on brackets 161 on guides 16, which maintain the chains in contact with the sprocket wheels 15. The guides 16, the shaft 14, and the wheels 15 can swing backwards and forwards about the shaft 9 as the loops 21 of chains approaching and leaving them vary in length. Two or more chains and tube frames placed in line two or more together may be used, three chains being shown employed, and each shaft being furnished with three sprocket wheels. The main portions of the chains are driven continuously by passing around sprocket wheels 361, 47 on shafts driven by bevel gearing. The chains also pass around idle guiding- sprockets. The wheels 47 engage both the upper parts of the chains and also the lower parts thereof. These lower parts are guided by curved guides 51 connected by links 54 and suspended by rods 50 from bosses on the shafts of the wheels 47. The chains form loops 55 between the guides 51, which have semi-circular or other curved guide channels for the passage of the rollers 18 on the chains. Each wheel 47 passes between the two guides with which it is used so as to engage with the chain 11 in the part guided by the channels in the guides 51. The guides are arranged to allow of the passage of the parts by which the tube frames are attached to the chains. Specifications 25728/97 and 242,682 are referred to.

[Classes 36 and 38 (i)] To prevent ionization in the spaces between the conductor a and the innermost layer of laminated dielectric b in a high-tension cable, joint, or bushing the spaces are screened by composite metallic and insulating tapes so arranged that no exposed metallic edges or surfaces thereof are presented to the innermost dielectric layer. As shown in Fig. 2 a paper tape d, with or without a metallized inner surface f, is lapped on the conductor, the spaces e between the turns of the tape being screened by a further wrapping of metallized paper tapes g which is so folded that the metal coating h is almost completely enclosed. The coating h is conductively connected to the conductor at intervals. The conductor may be provided with a smooth surface as described in Specification 454,449. The screening tape g may be formed by coating a metal tape with insulating material. A single metallized paper tape may be folded in such a manner as to form a double-thickness screening tape, similar to the tape g, mechanically and electrically connected to a single-thickness underlying tape similar to the tape d. Fig. 4 shows one such method of folding the tape, whilst Fig. 6 shows a construction wherein the tapes d, g are of similar cross-section. The tapes may be applied longitudinally of the conductor instead of helically. The outer surface of the dielectric may also be screened in a similar manner. Specification 517,225 also is referred to.
