Title: Process and apparatus for treating fibrous articles with an aqueous  treating liquid
IPC: D06B5/12
Filed: 1972-03-09
Abstract: 1381923 Treating textiles TORAY INDUSTRIES Inc and HISAKA WORKS Ltd 9 March 1972 [15 March 1971] 10969/72 Heading D1L Fibrous articles are treated with an aqueous liquid by a process comprising (i) charging fibrous articles into at least one treating chamber between upper and lower horizontal partitions and forming in each chamber a stratum of articles extending horizontally on the lower partition (ii) circulating the aqueous treating liquid only at a flow rate of 10 to 30 litres per minute per kg. of said articles through the upper partition and then the lower partition in a direction normal to the partitions or vice versa. The fibrous article stratum has an apparent filling density of 0.09 to 0.16 g/cm<SP>3</SP> under atmospheric conditions, and a thickness in the treating liquid having the relationship, L 1 #0.9L 2  where L 1  is the distance between the upper and lower partitions and L 2  is the thickness of the article stratum in the liquid under no pressure or stretching forces. The fibrous article stratum has also a resistance of 0.2 to 0.5 kg/cm<SP>2</SP> to the flow of the liquid. The articles may be superposed in two or more chambers. The stratum is preferably formed of yarns in muffs with the spaces between the muffs filled with fillers which do not allow penetration by the treating liquid. Suitable apparatus for carrying out the process consists of an outside tank 31, an inside casing 32 and a header 33. The bottom 34, of tank 31 is connected to alternate direction pump 35 through a conduit 36. A heater 60 is included in bottom 34. Inner casing 32 includes a cylinder 37 connected at the bottom end to pump 35 through a conduit 38, and an outside cylinder 39 defining a treating space 40 between the inside surface of the outside cylinder 39 and the outside surface of the inside cylinder 37. A header 41 closes the upper end of the treating space 40. The treating space 40 contains three chambers 44, 45, and 46 independent of each other. Horizontal partitions 47, 48, and 50 having a plurality of apertures 49, for allowing liquid to pass therethrough define the chambers. The filler may be selected from natural and synthetic resins, metallic materials and wood. The fibrous material may be loose fibres, filament tows, slivers hank-formed yarns, muff-formed yarns, knitted fabrics or bulky woven fabrics. The treatment may be dyeing or oiling wherein the treating liquid contains at least one dye or one oiling agent. After treatment the fibrous articles are preferably dried e.g. by blowing hot air through the treated stratum of fibrous articles whilst in the treating chamber.

Filed: 1940-07-01
Abstract: 536,558. Photographic shutters. KODAK, Ltd. (Eastman Kodak Co.). July 1, 1940, No. 11124. [Class 98 (i)] In a photographic shutter of the type in which a master-member 18 tensioned by a setting- lever 3 causes, on its release by a trigger 2; oscillation of a blade-ring 31 to effect an opening and closing movement of the blades 34, a spring latch 13 is provided which is movable manually into position to engage a moving part of the shutter mechanism when the blades are substantially fully open, to retain them in this position for focusing, the latch automatically moving to inoperative position upon subsequent movement of the setting lever in order that it may not inadvertently be in action when the exposure is made. In the form shown, the latch is mounted on the side of the shutter casing and engages, when pressed inwardly as shown in Fig. 4, a shoulder 26 on an arcuate shoe 22 which carries the setting-lever and moves in a groove 23 in an internal plate in the shutter. The master-member 18 is thus arrested when the blades are open. Subsequent movement of the setting lever to the position shown in Fig. 2 to set the shutter releases the spring latch 13 so that it moves out to the inoperative position. In a modification, the latch 13 is replaced by a spring-pressed button carrying a latch member which engages the shoulder 26.

Title: Thiazyl sulphides
IPC: C07D277/36
Filed: 1942-08-11
Abstract: 559,338. Preparations of thiazyl sulphides. SIBLEY, R. L., and MONSANTO CHEMICAL CO. Aug. 11, 1942, No. 11253. [Class 2 (iii)] Di-arylene-thiazyl disulphides are prepared by oxidizing the corresponding mercaptoarylenethiazole by means of a hypochlorite solution by a process which is characterized in that the oxidation is carried out at a pH corresponding to 550-600 millivolts as measured by the system Sb-Sat. calomel, and the solution is maintained at this value throughout the oxidation. The temperature is preferably maintained in the range 10-30‹ C. during the oxidation. The preferred procedure is to add a solution of a hypochlorite containing 8-10 per cent. active hypochlorite to an alkaline thiazole solution while maintaing the reaction mixture at the desired pH by the concurrent addition of a mineral acid. The amount of hypochlorite required is approximately twice that indicated by theory. In examples, (1) an aqueous solution of sodium hypochlorite is added to an aqueous solution of sodium mercaptobenzothiazole, the pH value being adjusted to a value corresponding to 600 millivolts on the Sb-Sat. calomel system and maintained at this value by the concurrent addition of 40 per cent. sulphuric acid. The insoluble product is filtered. (2) As in example (1) using slightly varying quantities of reagents. (3) As in example (1) but using as the starting material 4-phenyl-mercaptobenzothiazole to produce di-4-phenyl-benzothiazyl disulphide. (4) As in example (1) but using as the starting material 5-chlor-mercaptobenzothiazole to yield the corresponding product.

Abstract: 840,677. Liquid-blast switches. REYROLLE & CO. Ltd., A. April 10, 1957, No. 11776/57. Class 38 (5). In a liquid-blast switch in which the relativelymovable contacts 13, 19 are separated in a fixed turbulator 14 having vents 16 in its side wall through which arcing products are discharged, a nozzle 30 is secured to the movable contact 19, through which nozzle a jet of liquid is ejected across the arcing- tip of the movable contact 19 during contact separation. The moving contact 19 is of rectangular section and is secured to a bobbin 28 screwed on to the lower end of a hollow cylinder 22 which slides on a fixed piston 23. Thus when the contact 19 is moved downwardly to open the switch, the downward movement of the cylinder 22 causes the liquid in the cylinder to be ejected by the fixed piston 23 through the nozzle 30 which directs the jet of liquid across the tip of the movable contact towards the vents 16. In a multibreak switch a number of the units shown may be mounted one above another in a vertical tubular tank and are disposed along and spaced around a single operating-rod having forks engaging the bobbins 28. Specification 766,592 is referred to.
