Title: Process for the coloration of textile materials
IPC: D06P3/10
Filed: 1961-08-11
Abstract: Textile materials, the fibres of which contain hydroxyl or carboxylic acid amide groups, are dyed or printed with an aqueous preparation containing a water-soluble reactive dye, an alkali metal or alkaline earth metal salt of a carboxylic acid having at least 2 carbon atoms that yields a carbonate when heated above 80 DEG C. and a free carboxylic acid in an amount such that the preparation has a pH below 6, and fixing the dyeing by heating above 100 DEG C.  The specified salts are of the following types wherein Me represents an alkali metal or alkaline earth metal equivalent:-  (a) <FORM:0981195/D1-D2/1> , (b) R-C­C-COO-Me wherein R is H or a hydrocarbon, especially non-alkyl, radical, (c) <FORM:0981195/D1-D2/2> where x is 0, 1, 4, 5, 6, 7 or 8 and R1 and R2 are H or a hydrocarbon radical and at least one of the two radicals must be H when x is greater than 1, (d) <FORM:0981195/D1-D2/3> wherein x is 0-6 and R is as above, (e) Me-OOC-C­C-COOMe, (f) R-CHOH-[CH2]x-COO-Me and R-CO-[CH2]x-COO-Me wherein x is 0, 1 or 2 as R is as above, especially a low alkyl, (g) MeOOC-[CH2]x-CO-[CH2]y-COO-Me wherein x and y are 1-4, and (h) <FORM:0981195/D1-D2/4> wherein R1 and R2 are hydrocarbon radicals, especially low aliphatic, cycloaliphatic and aromatic radicals.  The free carboxylic and is preferably a mono- or dibasic acid of 1-6 carbon atoms.  Numerous types of suitable reactive dyestuff are specified.  Specified fibres to be dyed are natural and regenerated cellulose, wool, silk and polyamide fibres.  Examples of padding and printing cellulose fibre fabrics are given. Specifications 712,037, 723,471, 740,533, 798,121, 891,248 and 898,094 are referred to.

Title: Improvements connected with the excitation of dynamo electric machines
IPC: H02J3/38
Filed: 1925-11-19
Abstract: 261,541. English Electric Co., Ltd., and Bolton, R. A. R. Nov. 19, 1925. Switching-systems; protective arrangements.- Generators, such as exciters 1, 2 are connected to bus-bars 5, 6, through circuit breakers 9, 10, and the bus-bars supply highly inductive loads such as the fields of alternators. It is therefore necessary to shunt a discharge resistance 21 across the bus-bars 5, 6 when the last of the breakers 9, 10 open. This is effected by auxiliary switches 17, 18 arranged in series with the resistance 21 and adapted to close at the instant that the associated breakers open, and similar resistance 22 is provided for bus-bars 7, 8 supplied by generators 3, 4. A switch 27 is provided for interconnecting the two sets of bus-bars, and also for rearranging the discharge circuits so that all the auxiliary switches are connected in series with one or a parallel arrangement of both resistances 21, 22.

Abstract: 976,602. Momentary-contact switches; pressbutton retractive switches. CUTLER-HAMMER Inc. July 31, 1962 [July 31, 1961], No. 29347/62. Heading H2B. When trigger 12 is moved to the right against a compression spring 27, the lower sides of flanges 36d on an operating member 36 engage tabs 26c to depress a spring blade contact member 26 downwardly to make contacts 18, 32, but with continued movement in the same direction against the increased resistance of spring tabs 34b the flanges 36d move off the tabs 26c and allow member 26 to spring upwards and break the contacts, Fig. 8, such that when trigger 12 is released the flanges pass back under the tabs and thus do not actuate the contacts during the return movement. A spring-loaded ball 42 indicates the position at which contacts 18, 32 are made by engaging in a hole 46 formed in a frame 14 which provides a guide for movement of trigger 12.

Title: Improvements relating to endless conveyors
Inventor: ROOKE SYDNEY WILLIAM
IPC: B65G47/96
Filed: 1967-06-26
Abstract: 1,208,893. Endless conveyers for sorting parcels &c. SOVEX Ltd. 19 June, 1968 [26 June, 1967], No. 29403/67. Heading B8A. An endless conveyer having a surface 1 which is disposed in a tilted attitude at least at discharge stations has discharge controlling gates 10 which travel with the conveyer. As shown in Fig. 1, a series of load carrying slots 1 each bave wheels 4, 4, running in rails 5, 5, and are connected to an endless traction chain 2. A gate 10 is pivotally mounted on each slat 1 at 8 and is normally held in the position shown by a roller 11 engaging a slot 12 in a plate 13 rigid with the gate 10. The roller 11 is displaceable at a discharge station by a roller 19 acting on a ramp 18. This permits the gate 10 to drop as a roller 23 follows a ramp 25. The latter has a flexible tail 28 which permits the lowered roller 23 associated with previously opened gates 10 to pass by the ramp 25. The gates retum to closed position under the action of gravity as the endless chain passes around a return sprocket. Alternatively a ramp may be provided to deflect the roller 23 back to its higher level. In Figs. 3 and 5, pairs of slats 43, 43 are hinged together at 44, and in their normal position are inclined (Fig. 3) to provide a V-shaped receptacle for articles (not shown). Rollers 53 are each carried by a parallel linkage of which the appropriate slat 43 forms one side. At a discharge station, the roller 53 appropriate to the side on which discharge is intended to take place, is permitted by the retraction of a track section 55 to drop down to a rail 46 at a lower level. The section 55 is operated by a solenoid 56 (Fig. 5) by pin wheel or other mechanism. To permit discharge of a long article a number of successive gates may be opened simultaneously.

Abstract: 1433477 Brakes associated with looms FREDERICK GREENWOOD & SONS Ltd and DAVID CRABTREE & SON Ltd 27 April 1973 [24 June 1972] 29710/72 Heading F2E [Also in Division D1] In a gripper loom, as shown in Figs. 1 and 2, two mounting brackets 12, each for a spool of the loom, are secured to the top of a cross beam 10 of the carrying frame. Each spool has a flanged end plate 14; the spools are not coaxial, having axes 16, 18 respectively. A brake pad 24 is provided for each end plate 14 and is secured to a spring mounting plate 22 which urges the pad away from the end plate 14. In the position of Fig. 2 the brakes are applied by a compression spring 26 urging downwards, by a circlip 28, an actuator rod 20 whose bevelled head 20A forces apart the spring mounting plates 22. At an appropriate time a cyclically-movable component of the loom or a mechanism connected thereto engages the lower end of rod 20 and pushes it upwards to release the brakes. In Fig. 5, pads or shoes 24 are connected directly to rod 20 and are applied to the inner surfaces of axially-extending rims, acting as brake drums, on the end plates 14. In Figs. 9, 10, brake shoes in the form of spring steel strips 60 are applied to the outer surfaces of the axially-extending rims, again acting as brake drums. In this case each pad or shoe has its own actuator rod and spring, and release is effected, simultaneously or otherwise, through the agency of pivoted release levers 50A, 50B, which move the rods downwards. In Fig. 8 (not shown), the spring steel strips are replaced by brake pads incorporating friction material.

Abstract: 1,261,707. Extracting carbonaceous materials. COAL INDUSTRY (PATENTS) Ltd. 17 June, 1969 [21 June, 1968], No. 29744/68. Heading C5E. A method of extracting at least part of the carbonaceous content of a carbonaceous material, e.g. coal, coal tar, anthracene paste, or naphthalene base oil, comprises treating the material with an extractant fluid at a pressure and at a temperature above the critical pressure and temperature of the fluid, and subsequently reducing the pressure to separate the extracted part from the fluid. Extractants referred to are methane, ethane, propane, ethylene, propylene, ammonia, chlorine, carbon dioxide, benzene, toluene, pyridine, and ethyl- and (di)methylamine. Specific examples are the de-ashing of coal with benzene, extracting coal tar with ethylene to recover oils and pitch, and extracting pitch and anthracene paste with ethylene. In this last example anthracene and naphthalene are recovered. The method may be combined with a coal carbonization process, e.g. in a fluidized bed of coal to which the extractant is delivered, carbonization products being carried off by the extracfant. In all the examples, the separated extractant, after recompression, is recycled.
