Title: Improvements in or relating to the production of soap
IPC: C11D13/04
Filed: 1943-02-24
Abstract: 571,145. Manufacture of soap; saponaceous compositions. COLGATE-PALMOLIVE-PEET CO. Feb. 24, 1943, Nos. 3029 and 3030. Convention dates, March 25, 1942. [Class 91] In the manufacture of soap by the saponification of a fatty acid ester of a lower alkyl monohydric alcohol in a saponification zone, the liberated alcohol being removed by distillation, the reaction mixture is flashed into a zone at a pressure below that of the saponification zone to effect distillation of the alcohol. Sub-atmospheric to super-atmospheric pressures may be used. One form of the method is to force the reaction mixture through a heated pipe; the temperature and pressure in the pipe may be cyclically varied to create increased turbulence therein. The reaction mixture may be contacted throughout the reaction vessel or just prior to admission to the flash chamber with a heated inert gas, such as superheated steam, to effect heat economy, &c. The esters used are those of alcohols of 1 to 6 carbon atoms and of fatty acids of preferably 12 to 20 carbon atoms. Mixtures may be used and of a list given the following are exemplified: ethyl and methyl esters of coconut oil fatty acids, olive oil fatty acids and tallow fatty acids, and amyl esters of garbage grease fatty acids. Monoesters of polyhydric alcohols may be used in admixture therewith. Besides the usual caustic alkali saponifying agent, other organic and inorganic bases are listed, such as pyridine, methyl morpholine, and amines. The latter may be in other than aqueous solution or anhydrous. The soap mixture obtained is subjected to the usual cooling prior to extrusion, spraying, atomizing into compressed air, drum drying, &c., to form bars, granules, hollow particles, flakes, &c. The temperature and pressure in the reaction vessel or the flash chamber or the cooling of the soap mixture may be controlled to allow of the retention of part of the alcohol, water, or saponifying agent solvent in the soap product. A long list is given of suitable adjuvants which may be added to the soap, either with the soap-making ingredients or after its production. This includes other soaps, builders, softening agents, fillers, antiseptics, preservatives, medicated agents, abrasives, gums and solvents.

Abstract: 595,271. Glazing bars. ROBINSON, KING & BRITISH CHALLENGE GLAZING CO., Ltd., and HOLLINGTON, A. H. J. Feb. 8, 1945, No. 3238. [Class 20(iii)] A glazing bar is attached to a roof member by a stop bracket having a dovetail groove 55 formed by upwardly-convergent flanges 12 in which the correspondinglyformed base 5 of the bar slidably engages, a second groove 56 at the bottom of the groove 55 containing and holding against rotation the square portion of a screw device for fixing the stop bracket either to the base of the glazing bar or to a steel roof member. As shown, a screw 14 passes through a hole in the bracket and through a square nut 13 in the groove 56 and engages the underface of the base 5 of the bar, so locking the bar to the bracket. The bracket is secured to the purlin 21 by an intermediate shoe 15, which is attached to it by the screw 14 and to the purlin by wood screws. Vertical flanges 18 on the shoe 15 embrace draught fillets 22 with sealing strips 23 engaging the underface of the glass. Alternatively, the bracket may have lateral flanges which are screwed to the purlin, the shoe 15 being omitted. The glazing bar shown carries resilient rods 9 against which the glass is held by lateral projecting portions 10 of a sealing strip. A construction in which the bracket is bolted to a steel purlin by a bolt having a square head held in the groove 56 is also described. Specification 535,730 is referred to.

Title: Process for dyeing or printing fibrous materials of aromatic polyesters
IPC: D06P3/54
Filed: 1961-01-27
Abstract: Aromatic polyester fibres are dyed or printed with a 5-acylamino-1 : 9-isothiazole-anthrone dyestuff of the formula <FORM:0898912/IV (c)/1> wherein A represents a benzene or piperidine residue, the residue A or the anthrone residue, if desired, containing further substituents.  The dyestuff is employed in an aqueous dispersion, if desired, together with swelling agents such as benzoic or salicyclic acid, o- or p-oxydiphenyl, mono-, di- or trichlorobenzene, phenyl-methyl-carbinol or diphenyl.  Dyeing may be effected at the boil, or under pressure at temperatures above 100 DEG C., advantageously from a weakly acid dyebath.  Alternatively, the fibres may be padded with the aqueous dyestuff dispersion containing urea and thickeners, and then heated at a temperature above 100 DEG C., e.g. at 140 DEG C.-210 DEG C.  Fabrics containing polyester fibres and cellulose fibres may be padded with the dyestuff dispersion containing, in addition, a direct, vat or reactive dyestuff, whereby both fibres are simultaneously dyed.  Fabrics containing polyester fibres and wool may be dyed by the process with reservation of the wool.  Examples of dyeing and printing are given.  The dyestuffs are prepared by reacting 5-amino-1 : 9-iso-thiazole-anthrone with a benzoyl halide or a pyridine carboxylic acid chloride.  Specification 745,086 is referred to.

Abstract: 206,065. Jensen, C. A., (Jeffrey Manufacturing Co.). Sept. 5, 1922. Coal-cutting machines.-A truck for a coal-cutting machine a comprises a wheeled frame 1, Figs. 2 and 5, carrying a turntable 13 rotatable about a vertical axis, and a machine supporting frame 19 is vertically adjustable on the turntable and provided with longitudinal guides 20 in which the machine slides on to or from the truck. A supplemental guide frame 36 is detachably connected to the frame 19 by longitudinally movable hinge pins 35 to facilitate loading or unloading of the machine. When the machine is unloaded, the truck overbalances on to auxiliary wheels 12. The turntable is rotated by attaching the haulage cable of the machine to one of the superposed attachment devices 38 and is held in adjusted position by a locking pin. The frame 19 is vertically adjusted by nuts 18 on screws 17 driven through sprockets 26 by a common chain driven through the pivot pin of the turntable 13 by a motor 48 on the truck; each screw 17 may be disconnected from its sprocket by an independent clutch whereby the frame 19 may be tilted. The motor 48 also drives the truck through two-speed gearing while a brake 40 holds the truck when desired. The motor 48 drives worm gearing 50, 54, Fig. 12, which drives a shaft 55 through a friction disc clutch 56 controlled by a lever 57, which, when the clutch is uncoupled, applies a brake 59 to the shaft 55. The shaft 55 carries a pulley 102 driving a reel 96 for winding or unwinding electric cable and also drives a shaft 61 through a clutch coupling 62; a pinion 63 loose on the shaft 61 drives a truck operating sprocket 68 through a gear 66 and is itself driven either at high speed through a clutch 83 or at low speed through gears 72, 73 and a slidable pinion operated by a slide rod 77 and engaging a gear 65 fixed to the gear 63; the sprocket 68 and gear 66 are carried by a frame 69 pivoted at 70 and adjusted by screws. The clutch 83 is also adapted to drive bevel gearing 79, 84 and a sprocket 86 which operates the vertical screws 17. The clutch 83 is operated by a hand lever 89 and fork 87, Fig. 13, which are connected through a crank 92 with a member 93 slidably engaging the slide rod 77 controlling the low speed drive; when the low speed drive is engaged the member 93 prevents movement of the clutch 83 from its neutral position, while when the low speed drive is disconnected, a groove 95 in the rod 77 allows movement of the member 93 and the clutch 83 may then be connected either to drive the truck at high speed or to drive the screws 17. When the clutch 83 is engaged, the member 93 engages the groove 95 to prevent coupling up of the low speed drive. The coal-cutting machine is preferably as described in Specifications 206,292 and 206,427, whereby long wall or short wall working may be effected when unloaded, and arc wall working when loaded on the truck. The Provisional Specification refers to Specification 204,448.
