Title: Improvements in apparatus for the continuous mashing of malt
IPC: C12C7/06
Filed: 1960-02-25
Abstract: In an apparatus for continuously mashing malt, ground malt mash is fed from a grist case 30 through a rotary valve 31 and is conveyed by a feed screw 32, which admits hot water to it, into a first container 22 and after a rest period, a more activated conversion is obtained by under-letting effected by hot water and/or steam fed in through spray rings 46. After conversion separation of the spent malt from liquor is effected by a straining cone 36, the liquor being pumped by a pump 39 through a conduit 40 either to storage through conduit 42 or back into the top of the container via conduit 45 for passage through the mass of malt material therein to effect clarification, whilst the spent malt is conveyed through an opened sluice valve 25 and fed by a screw 27 <PICT:0976839/C6-C7/1> (synchronized with screw 32 to balance inflow and outflow of material) into the top of a second container 23. Strong liquor settling out in the screw 27 is collected in a sump 62 thereto and a pump 65 returns it via conduits 64, 66 to the top of the first container 22. The spent malt is then extracted a second time in container 23 by sparging hot water and/or steam fed in by spray rings 57 and a conical strainer 48 separates spent malt from liquor the latter being fed by a pump 55 and conduits 52, 54, 56 to storage whilst spent malt escapes via an outlet 49 and sluice valve 50 to a feed screw 51 which removes it either for disposal or conveyance by a pump 60 through conduits 58, 61 back to the top of the container. Both containers 22 and 23 are provided with several temperature indicating devices at several levels in order that control of the process may be effected; in addition all outlets are valve controlled, as shown, and if desired the first container may be isolated from the second, e.g. as is necessary when starting up the process.

Title: Improvements in or relating to mechanical metal drawing presses
IPC: B21D24/12
Filed: 1950-12-15
Abstract: 684,205. Cupping presses. CLEARING MACHINE CORPORATION. Dec. 15, 1950 [Aug. 7, 1950], No. 30640/50. Class 83 (iv). In a metal drawing press, the blank clamping slide and draw slide reciprocable therein, are actuated by separate mechanical linkages so that both slides move simultaneously towards the blank until the clamping slide reaches clamping position, whereupon the linkage associated with this slide causes a dwell thereof during which the draw slide moves through its drawing stroke, the linkages being actuated by a common oscillating shaft rockably mounted in the machine frame. A common shaft 76 drives, through gearing, crank-shafts 42, 43 on each side of the press, each crank-shaft being in two parts, Fig. 6, and driving, through eccentrics 46, rocker shafts 50, also in two parts. The rocker shafts are connected through linkages 52-56 and links 15, and linkages 59-66 and links 34, to the clamping slide 9 and draw-slide 8 respectively. The arrangement is such as to move both slides to the clamping position and cause the clamping slide to dwell thereat. The draw-slide then moves to draw and returns to the clamping position during the said dwell, under the action of cranks 68 carried on the shafts 42, 43 and connected by links 70 to the links 34. The clamping slide is supported on screws 10, having adjusting nuts 12, 13, and the draw slide is carried on screws 18 which are adjusted by a motor and gearing carried on the draw slide. Hydraulic cylinders 36, 39 provide counterbalancing while the slides are being adjusted. Specification 692,509 is referred to.

Abstract: 176,429. Touchstone, B. F., Gardner, T. E., Bangle, J. A., Sullivan, D. M., and Hardin, J. E. Oct. 29, 1920. Yarns, warping and beaming; dressing warps; guiding and tensioning yarns in warp form.- Warps 20 in sheet form are passed from section beams or direct from bobbins or spools around submerged rollers in washing-boxes and dyeing- vats and next around intergeared steam-heated drying-cans 70 and then, through a compensating- frame 85 and a slashing machine 80, direct to the loom beam. The warps are drawn through the various vats. by squeezing rollers, the lower rollers of which are driven by bevel-gearing from a shaft, which may be driven by an electricmotor arranged midway thereof. The slashing- machine is driven by belt-gearing from the shaft 74 of one of the drying-cylinders, this shaft being driven bv a belt 76 from one of the squeezing- rollers which draw the warps through the various vats, whereby the warps may be fed through the various parts of the apparatus at a constant speed. The compensating-frame has fixed rollers 88 and movable rollers 87, comprising sections of steel shafts, around which the warp passes, so that, when it is fed at a greater speed from the drying-cans than the speed at which it is taken up by the slasher, as for example when the slasher is stopped to interchange an empty beam for a full one, the rollers 87 fall and take up slack, so that the operation of doffing does not interfere with the continuous passage of the warp through the apparatus. Selvedge threads may be added to the warp from spools 91 on a creel 90 just before its passage into the slasher, which has a size box, drying-cylinders and splitting rods &c. The bobins may be creeled in groups with threads of successive bobbins in each group tied together.

Patent GB-689177-A (GB)
Title: Improvements in apparatus for straightening bowed weft threads in textile fabrics
IPC: D06C3/06
Filed: 1949-11-30
Abstract: 689,177. Feeding webs. ROBERTSON, J. D. Nov. 30, 1949, No. 30734/49. Class 100(i) [Also in Group XXXV] An apparatus for straightening bowed weft threads of textile fabrics, comprises a plurality of longitudinally-curved, rotatably-mounted, webengaging rolls longitudinally spaced between guide means, the web engaging under one roll and over the next adjacent roll, pivoted means separately supporting each roll perpendicular to the direction of travel of the weB and parallel to the pivotal axis of the adjacent roll or rolls and means for simultaneously rotating adjacent rolls in opposite directions about their pivotal axes, thereby causing the central portion and an edge portion of the web to have an unequal travel between the guide means. A web W passing between guide rolls 14 and 16 engages under a curved roll 10 and over a curved roll 12. The curved rolls are of known type having a longitudinally curved axle 30 on which the roll body is rotatably mounted by bearings 34, the outer surface of the roll being a tube of flexible material. The opposite ends 30<SP>1</SP> of each axle is non-rotatably secured in clamps 36 adjustably secured on members 38 by screws 39 passing through slots 38<SP>1</SP> in the members 36, the members 38 being pivoted by pins 40 to brackets 42. Each member 38 has a gear 46 thereon, anti-friction bearings 48 being provided between the member 38 and pivot pin 40. Each member 38 may be swung about the pivot pin 40 by rotating gears 52 on a shaft 54, rotation of any one of the gears 46 causing a like rotation of the opposite gear at the other end of the rolls 10 and 12 and a similar but opposite rotation of the other two gears 46. The shaft 54 may be rotated manually or by a reversible electric motor 56 controlled by a mechanism which detects the bow in woven fabrics. For example, known detecting apparatus wherein the differential of light intensity at light-responsive cells controls the operation of the motor. The cells may be arranged to respond to rays of light, reflected from the web or passing through the web. The rolls 10 and 12 occupy a neutral position when in the position shown in Fig. 6, in which the lines W<SP>1</SP> representing the path of travel of the centre of the web, and W<SP>11</SP> one of the edges, respectively, are equal in length. If the weft threads are bowed in the direction of the travel of the web, it is necessary to lengthen the path of travel of the central portion of the web, in which case the roll 10 is swung counter-clockwise and the roll 12 is swung clockwise as shown in Fig. 7 or to any suitable intermediate position. If the weft threads are bowed in the opposite direction, correction can be made by swinging the roll 10 clockwise and the roll 12 counter-clockwise. Specifications 613,450 and 633,104, [Group XXXV], are referred to.
