Abstract: 1439385 Knitting machines WILLIAM COTTON Ltd 29 July 1974 [11 Sept 1973] 42759/73 Heading D1C A take-down mechanism in a knitting, e.g. V-bed, machine comprises fabric-engaging means such as a draw-off bar 1, suitably weighted at 3 and attached at each end to one end of a cable or chain 7 whose other end carries a weight 6 to counteract part of the weight of the bar, the cables or chains 7 engaging respective freely rotatable wheels 8 on a shaft 11 which can be coupled by a clutch 14 to drive means 14a, 14b, 16 to raise or lower the bar 1 and thereby vary the takedown tension. As shown the invention is applied to a V-bed machine for knitting rib borders and each end of bar 1 carries a guide member 19 reciprocable along a guide 21. The wheels 8 are amounted with lost motion on the shaft 11 so that as one end of the bar sinks at the start of a new course this displacement is accommodated by the wheel to maintain a constant tension along the bar. On completion of a predetermined number of courses, as established by screws 28 on members 19 tripping switches 27 or by a further switch tripped by a timing chain, the clutch 14 which is preferably electromagnetic is engaged to rotate the shaft 11 anticlockwise and release the takedown tension for removal of the fabric, subsequent raising of the bar 1 by chains 22 trips switches 25 to deactivate the clutch again. The drive means 14a, 14b, 16 may be used to rotate the shaft clockwise during knitting to provide a positive take-down control.

In a process for the regeneration of an ammonium persulphate etching solution which contains therefrom dissolved copper, cobalt, iron, nickel and/or zinc, a persulphate-free mixture containing sulphate values of ammonium and the dissolved metal is separated from said solution and passed to the cathode compartment of an electrolytic cell, the remaining solution containing the persulphate from the original solution and other sulphate values being passed to the anode compartment of said cell, the dissolved metal in the catholyte being deposited upon the cathode and persulphate ions being formed at the anode during electrolysis, the resulting anolyte forming the regenerated etchant. Additional sulphate, e. g. the catholyte produced in a previous operation, may be added to the anolyte or to the original solution prior to separation therefrom of the persulphate-free portion of the exhausted etchant. Urea and ammonium thiocyanate may also be added to the anolyte. The persulphatefree catholyte may be obtained from the original etchant solution by condensing said etchant and crystalizing out therefrom metal sulphate and ammonium sulphate which is then redissolved in the water given off by condensing the original solution, the mother liquor forming the anolyte. The examples given use a platinum wire anode and a cathode of copper tubing, and the diaphragm cell formed by a porous porcelain cup within a glass beaker, the copper tube being wound as a helix about the porous cup and having water passed therethrough for better temperature control.

Title: Granulated bituminous concrete material and methods of manufacturing and using same
IPC: C10C3/14
Filed: 1961-12-01
Abstract: A non-adherent granulated bituminous concrete material is made by forming a heated mixture consisting of aggregate and bituminous cement at 175 DEG  F. or more, but less than 300 DEG  F., by mixing dry, heated aggregate with hot, non-foaming, liquid bituminous cement of 60-120 penetration in an amount sufficient completely to cover the aggregate particles, and then cooling the heated mixture to about atmosphere temperature by intimately contacting the particles thereof with a flowing stream of air, free of suspended solid matter, having an initial temperature not greater than atmosphere temperature while agitating the mixture so as to maintain the latter in particulate form.  Preferably, at the beginning of the cooling stage, the temperature of the mixture is 175-250 DEG  F.  The heated mixture may be precooled by contact with water before being air-cooled and water as a finely divided suspension, may be present in the cooling air. The heated mixture may be cooled, and agitated, by repeatedly lifting and showering portions of the mixture downwardly by gravity through a substantially horizontally flowing stream of air, e.g. by means of a revolving drum containing flights, or blades, and with its axis inclined to the vertical.  The cooling stream of air may flow with, or against, the stream of mixture.  Stone, gravel, sand, crushed rock, slag and limestone are specified aggregates. The bituminous constituent is an asphalt cement with a penetration within the above range.  A pigmentary coating may be applied to the product, preferably by the use of water-based paints.  The product may be stored and, on reheating, used to make pavings and floorings. The coloured product is laid cold.
