Abstract: 1312542 Recovery of barium KALI-CHEMIE AG 30 June 1971 [9 July 1970] 30696/71 Heading C1A Barium is recovered from residues (e.g. of black ash) from which barium sulphide has been leached, by suspending said residue in water and reacting with H 2 S or elemental sulphur when barium is converted into a water-soluble form and the solution, after separation from insoluble material, is processed to provide a desired barium compound. Treatment with H 2 S is preferably carried out at room temperature whilst reaction with sulphur is preferably at 80-110‹ C. The process may be repeated to increase the recovery of barium, and any calcium, or excess H 2 S present in the solution may be removed by treatment with barium sulphide solution to form Ba(SH) 2  and to precipitate calcium. Specified treatments of barium solution include treatment with CO 2  to produce barium carbonate and H 2 S which may be recycled or with acids to produce the corresponding salts. The barium containing solutions so obtained may also be used for leaching further quantities of barium sulphide from black ash.

Title: Improvements in sheet registering mechanism
IPC: B65H9/10
Filed: 1948-11-26
Abstract: 670,087. Feeding sheets. HOE & CO., Ltd., R. (Albrecht, A. J.). Nov. 26, 1948, No. 30797/48. Class 100 (i). Sheet-registering devices.-In a sheet side-lay registering mechanism a sheet-holding member has a perforated supporting surface and an abutment for engaging an edge of the sheet, and is frictionally moved in one direction to carry the abutment yieldingly against the edge of a sheet, suction then being applied through the perforated supporting surface to hold the sheet thereon, the sheet-holding member then being retracted to carry the sheet into registration. Generally, the apparatus is substantially the same as that described in U.S.A. Specification 2,231,914 in which sheets are conveyed to a. registering cylinder 1, and are then fed to a printing-machine. The sheets are urged to register against front stops 6 associated with grippers 7. A sheet-registering device comprising stripper fingers 5 on a shaft 4 throws off improperly registered sheets when operated from detecting fingers 6a. Lateral registry is effected by bars reciprocated axially of the cylinder; and associated with suction or gripper-finger means. As shown, suction bars 8, 9 are reciprocated axially by cam means, and each comprises an upper and lower member secured together and slidable in ball bearings in blocks fastened in the cylinder. The bar 8 (and 9) has adjustably secured thereon a plate 40 carrying a shoe 41 which is frictionally retained thereon by springs. The shoe 41 is adapted to engage under a sheet, has holes 44 through which suction is applied, and has an upstanding abutment 45 for engaging the side edge of a sheet. An adjustable stop bar 47 is secured on the cylinder or a block therein. In operation, a sheet is presented to the cylinder 1, registered against the front stops 6, and the bar 8 moved axially inwardly of the cylinder without suction being applied. The abutment 45 on the shoe 41, on engaging the side edge of the sheet, stops in that position, but the bar 8 continues its' inward movement to the end of its stroke. Suction is now applied to the shoe 41, and this is sufficient to hold the sheet on the shoe and the shoe against the plate 40 on the bar 8. The bar 8 returns, pulling the sheet with it until the abutment 45 on the shoe engages the stop 47, whereupon the bar and plate complete the return stroke leaving the sheet in registered position. The opposite side edge of the sheet can be registered instead by using similar devices associated with the bar 9. The shoe 41 may be of aluminium alloy sprayed with carbon steel.
