Title: Improvement in a process of and system for the softening of water
IPC: C02F5/02
Filed: 1944-09-08
Abstract: 580,991. Softening water. TRIGGS, W. W. (Dorr Co.). Sept. 8, 1944, No. 17193. [Class 46] A water-softening process producing a sludge containing suspended particles of calcium carbonate and magnesium hydroxide includes the step of subjecting the sludge to centrifugal forces so as to cause segregation of the sludge into a cake consisting substantially of calcium carbonate particles and into an effluent the suspension in which contains a substantial portion of the magnesium hydroxide particles. The cake is calcined to convert the calcium carbonate into lime suitable for use in the process. In the arrangement shown, water is fed to a mixer 1 and treated with soda ash and lime. The liquid with precipitates is then conveyed to a flocculating tank 2 containing slow-moving paddles. Afterwards the liquid is led to a sedimentation tank 3 where calcium carbonate and magnesium hydroxide settle out. The effluent passes to a tank 4 where it is treated with carbon dioxide. The resulting calcium carbonate is carried with the liquid to a flocculation tank 5 thence to a settling tank 6. The effluent from the tank 6 is softened water. The sludge from the two settling tanks 3, 6 is conveyed by pipe 26 to a centrifuge 7, where the main portion of the calcium carbonate is separated in the form of.a cake from most of the magnesium hydroxide which flows away with the effluent. The cake is delivered to a kiln 8 where it is calcined, the carbon dioxide being utilized in the tank 4 and the lime being conveyed to a slaker 9. The slaked lime is conveyed to the mixer 1. If the water to be softened contained soluble iron and aluminium compounds these are removed in the form of hydroxides, with the magnesium hydroxide.

Abstract: 584,464. Upper-conforming means; stapling. KAMBORIAN, J. S. Sept. 8, 1944, No. 17200. Convention date, Jan. 15. [Classes 17 (i) and 89 (iii)] In an upper-conforming machine as described in Specification 541,643, comprising a pair of oppositely rotated ribbed rolls 22, 23, Fig. 26, for imparting an uninterrupted pull to the upper progressively along its margin, an abutment 34 which engages the shoe bottom to oppose the pull of the rolls and also engages the inner face of the insole rib, and a wiping member 53 wnich wipes in the upper over the edge of the insole and compresses it and the insole rib against Its abutment, the wiping member is formed as the outside former and driver guide of mechanism adapted to form staples from continuous wire and drives them, parallel to the shoe bottom, into the upper margin and insole rib while these are compressed between the wiping member and the abutment. As shown, Fig. 4, the rolls 22, 23 are carried by shafts 21, 24 driven by the main shaft 4, the shaft 24 being carried by a slide 26 which is movable forwardly, against the action of a spring 17, by a treadle, to permit separation of the rolls. The abutment 34 is carried adjustably by the slide 26. The shaft 4 also drives a cam shaft 40 which carries an eccentric 43 and a cam 45, Fig. 4, formed with upper and lower cam grooves 46, 47 and a cam rib 48. The wiping member 53 is carried by a slide 49 reciprocated by the eccentric 43 and is formed with a groove 58 to receive the staple driver 59. The latter is retracted by a roll 67 in the cam groove 47 and moved forwardly on its driving stroke by springs. An inside former 68 is reciprocated into and out of the groove 58 by a lever 72 and the cam rib 48. A staple length of wire from a reel is fed in front of the member 53, between lugs 69, 70 of the inside former, by feed pawls 83, 84 on a slide 82, Fig. 24, reciprocated by the cam groove 46. 81 is a hold back-pawl and the wire from the reel is tensioned by a roll and spring. Figs. 4 and 26 show the member 53 in its staple driving position. When the margin of an upper has been threaded between,the tensioning rolls 22, 23 and the machine is started, the member 53 and driver 59 are in retracted position and the inside former 68 raised. Rotation of the rolls 22, 23 now imparts a tensioning pull progressively to the margin of the upper. For each rotation of the shaft 40, a length of wire is fed in front of the member 53, the former 68 is lowered, the member 53 advances to cut off the length and bend it to staple form about the lug 69, to carry the staple up to the upper and to wipe the upper and compress its margin against the rib, and the driver advances to drive the staple, which may be clinched by the abutment 34. It is preferred to form and drive staples at the rate of about one hundred and seventy-five a minute, the ratio of rotation speed of the shaft 40 to that of the roll shafts 21, 24 being four to one.

Title: Improvements in or relating to means for maintaining the tension in yarn during winding from one package to another
IPC: B65H59/04
Filed: 1930-06-05
Abstract: 356,792. Tensioning yarns or warps during winding &c. BRITISH CELANESE, Ltd., 22, Hanover Square, London. June 5, 1930, No. 17372. Convention date, June 5, 1929. [Classes 120 (ii), 120 (iii), and 142 (iv).] Substantially uniform tension is maintained in yarn being passed from package to package by means of a brake acting on the supply package and operated by a member which is controlled by the tension of the yarn in transit and by the quantity of yarn remaining on the supply package. In a warp-sizing machine the warp yarns 2 are unwound from the beam 1, passed over the sizing roller 5, squeezing-roller 6, round the drying drums 8 to the winding beam 9. When the tension in the yarn decreases, the roller 10 descends and the weighted lever 11 swings about its pivot 12 and so causes the lever 18 pivoted at 19 to lower the lever 22, whereby the brake band 26 is tightened and the tension in the yarn restored to normal. As the diameter of the warp beam 1 decreases, the pivot 12 of the lever 11 descends and causes the lever 22 to rise, so loosening the brake band 26. The hand-wheel 24 allows the braking force to be adjusted, and a slotted lever connection at 20 allows the warp beam and carriage to be readily replaced. A guide roll 32 prevents the size from running down the warp when the beam becomes small in diameter.
