Abstract: 234,741. Linotype & Machinery, Ltd., and Kenyon, W. G. Oct. 20, 1924. Gripper mechanism; blankets and impression surfaces.-Sheets are held to the cylinders 5 of printing-machines by means of grippers 20 and gripper pads 1, a number of which are frictionally held on a shaft 2, and according to the present invention the outer ends of the pads 1 are capable of being adjusted radially to suit varying thicknesses of the sheets carried by the cylinder and of the blanket or like covering 15. This adjustment is effected by mounting the shaft 2 so that it can be moved in an arcual path, and arranging the pads with capacity for angular adjustment relatively to the shaft 2. Eccentric journals 3, 3<a> are secured to the shaft 2, and mounted in bearings 4 in the cylinder 5. The pads 1 are formed with split bosses 7, in which are linings 9 and screws 8 to secure the pads frictionally on the shaft 2. The shaft 2 is rotatable in the cylinder 5 by means of a key engaging a square end 12 on the shaft 2, and to adjust the shaft it is rotated together with the journals 3, 3<a>, to an extent which is determined by a scale on the boss 3b concentric to the journal 3<a> and coacting with a pointer 13 on one of the bearings 4. The shaft 2 is held in its adjusted position by a lock-nut 11 with holes 14 for receiving a tommy bar. The pads 1 may be arranged to secure the end of the blanket 15 in position, or the blanket may be held by separate plates. The pads 1 may be formed with recesses corresponding to these plates so as to bring the edges of the pads close to the edge of the blanket.

Title: Improvements in or relating to the recovery of anions
IPC: C01G1/00
Filed: 1955-01-24
Abstract: Arsenate, chromate, molybdate, tungstate or vanadate ions are recovered from an aqueous solution containing two or more of said ions and concurrently partially or completely separated, by suitably adjusting the pH and then passing the solution through an anion exchange substance having diethylamino groups at the exchange positions: the ions are then eluted, e.g. with aqueous alkali metal hydroxide.  Arsenates are most readily adsorbed at a pH of 7.3, molybdates at pH 4-5, tungstates at pH 6-7 and vanadates at pH 4; in sulphuric acid solution chromates are best adsorbed at pH 5 to 2N. In the examples, an anion-exchange resin in hydroxide form derived from cross-linked polystyrene was used to separate solutions of (1) ammonium molybdate and potassium chromate in 2N hydrochloric acid wherein the chromate only was adsorbed; (2) ammonium molybdate, potassium chromate, ammonium vanadate and sodium aesenate in N sulphuric acid wherein molybdate and chromate only were adsorbed; after elution the eluent was brought to a normality of 0.2 with respect to sulphuric acid, treated with sulphur dioxide to reduce the chromate to chromic salt and passed through the resins; only the molybdate was adsorbed; and (3) ammonium vanadate and potassium chromate in 0.5 N sulphuric acid whereby chromate ions were adsorbed. Elution was in each case carried out with 0.5 N sodium hydroxide.
