Title: Method and apparatus for crimping fibres
IPC: D02G1/12
Filed: 1957-02-18
Abstract: In a process for permanently crimping cellulosic fibres, e.g of regenerated cellulose, cotton, linen, hemp, ramie or jute, in the form of a rape or sliver of carded fibres or a tow or bundle of continuous filaments which may have been twisted into yarn, the fibres are fed continuously into a closed crimping zone against a mass of crimped fibres, advanced along the zone to a discharge point at a point in advance of which the fibres are impregnated with material having groups which react with cellulose under heat to fix the crimp in the fibres, and are then heated to produce such reaction.  The crimped fibres may be advanced to the discharge point at a predetermined rate dependent upon the dwell of fibres in the zone during which the impregnant is, at least partially, cured.  The impregnant may be (aqueous solutions of) urea formaldehyde precondensates such as sesquimethylol urea, formaldehyde precondensates of modified ureas such as dimethylol ethylene, propylene or butylene ureas, methylol melamines such as mixtures of dimethylol and trimethylol melamines or tetramethylol and pentamethylol melamines, methylated - methylol melamines such as dimethyl trimethylol melamines.  Examples of added catalysts include solutions of <PICT:0824399/IV(c)/1> magnesium chloride hexahydrate or 2-methyl-2 - aminopropanol - 1 - hydrochloride, hydrogen chloride, which may be in gaseous state.  Examples of added cationic softeners include stearamidoethyl urea monoacetate and dimethyl ammonium methyl sulphate of monostearyl-metaphenylene diamine.  Polyvinyl alcohol may also be added to the impregnating liquid.  As shown, filament tow or yarn is passed through feed rollers 11 into an impregnating solution 12 in a tank 13, removed through squeeze rolls 14, fed through a drier 15 and around guide rolls 16 to a guide 17 and is fed by adjustably spring-loaded driven rollers 29, 30 into a crimping chamber formed by sleeves 25, 26, 27, which may be heated by controlled electrical units 45, 46, 47, within blocks 20, 21, 22. The sleeves are joined by collars 50, 51 which have ports 52, 53, communicating with pipes 54, 55, through which fluid, regulated by valves 56, 57, may be fed to the chamber: fluid, regualted by valve 65, may be introduced to sleeve 25 through ports 60.  Steam and vapour escape through ports 76, 77, 78 and passages 79, 80, 81. Crimped filaments &c. 69 are withdrawn through a hollow loading plug 68 by rollers 71, operated at a predetermined and adjustable speed relative to the filaments feed rate, and may be passed through an oven 73 for final curing of the impregnant before winding. Catalyst(s) may be introduced through pipe 64 or 54 and/or impregnant introduced through pipe(s) 64, 54 and/or 55, and the curing may be effected in or divided between sleeve 27 and oven 73; softening agent or lubricant may be introduced through pipe 54 or 55 or into the top of sleeve 27.

Abstract: 720,089. Variable-speed gearing. WOOLER, J., and WOOLER, R. June 6, 1952 [March 8, 1951], No. 5646/51. Class 80 (2). An oblique shaft 3a is rigid with a socket 2a in splined engagement with the end of the driving shaft (not shown) but is slidable through splines in an axially-fixed eccentric disc 21a which, through rods 26a and arms 7a, oscillates spindles 12a each carrying, through a one-way ball clutch 63a, a toothed pinion 6a meshing with a common gear 11a on a driven shaft 1a. The end 19a of shaft 3a is journalled in a ball bearing 20a slidable in a part 16a of an inner casing 10a and the socket 2a is journalled in a ball bearing 34a slidable in a part 37a of casing 10a. The outer end of the socket 2a is connected, through a ball bearing 9a, to a threaded socket 44a engaging a threaded part 45a of a spindle 42a carrying a worm 43a meshing with a worm wheel on an adjusting spindle (not shown), so that by turning the latter the socket 44a, and with it the socket 2a and shaft 3a, may be adjusted longitudinally. For gear variation, the casing 10a is held stationary in an outer casing 10d by a band brake 64. When direct drive is required, brake 64 is released and a shoe clutch 66 is engaged to connect casing 10a to shaft 1a. This clutch is controlled by a slidable cone 70 urged by a spring 82 to engaged position and adapted to be disengaged by an operating fork 78. A gear 95 splined on shaft 1a and controlled by a fork 111 is always in mesh with planets 100 carried by a member 96 secured on an output shaft 102a. The planets 100 also mesh with an annulus 101 adapted to be held stationary by a band brake 102. When so held, shaft 1a drives shaft 102a at reduced speed. If the brake 102 is released and gear 95 moved to engage internal teeth on member 96, shaft 102a is directly connected to shaft la. In order that reverse drive may be obtained, each spindle 12a may carry, through oppositely-acting one-way clutches, two pinions 6a, and gear 11a may be axially slidable on shaft 1a so as to engage either set of pinions.

Title: A system of sinking of shafts by means of freezing
IPC: E21D1/12
Filed: 1920-02-28
Abstract: 139,520. Soc. Anon. des Charbonnages de Beeringen. May 8, 1918, [Convention date]. Freezing the ground.-In sinking shafts by the freezing process, at the foot of the shaft joints are made at each bore-hole to insulate the ground water so that the hydrostatic equilibrium column used in forming such bore-hole may be detached for use in forming other bore-holes. In operation, when the shaft a approaches the water bearing strata, its base c is widened and an annular recess n is formed ; in the recess are placed two sets of holders m supporting guide-tubes 1, the recess being then filled with concrete. Through the guide-tubes, borings are made to near the water bearing strata and tubes 2 are lowered into the holes and fixed to the soil and the guide-tubes by cement p. An equilibrium column 3 is then connected to one of the guide-tubes by a telescopic joint 4; through this column, a boring is then effected from the ground level to pierce the water bearing strata, by means of rods 7, freezing tubes 5 are lowered into the boring, a collar thereon engaging a sleeve at the top of the respective tube 2; radial screws, passing through the guide tube, centre the freezing tubes. The rods 7 are then removed and a longitudinally divided chamber 11 is placed around the guidetube and connected to vats 12 for circulation of freezing liquid; the liquid within the tube 2 is thereby frozen to make a temporary joint, thereby permitting removal of the equilibrium column, after it has been emptied of water, and permanent closure of the guide tube by means of a stuffing-box 15. When the borings are finished, the various freezing tubes are connected with annular headers 16 supplied with freezing medium by columns 17 which may be those previously used as equilibrium columns; the ground is thereby frozen. The columns 17 are slidably guided by collars to allow for contraction, and their upper ,ends are adjustably supported by means including dynamometers, auxiliary supports being also provided which come into operation if the primary supports yield.
