Abstract: 1276722 Metal sheet feeds SCHLOEMANN AG 8 May 1969 [30 May 1968 8 Oct 1968] 23429/69 Heading B3W A device for positioning the rear end portion of a plate 9 to be cut by a cross-cut shear comprises primary conveying means, such as rollers 5, 6, and a pusher member 15, 18 for continuing the feed movement beyond the rollers. In operation a sensor such as photo-sensitive devices 12, 13 produce a signal to stop the drive to the rollers and actuate the shear blade 4 when the rear edge of the plate passes them. A gauging stop 11 associated with a run-out roller table 7, is then moved into the path of the plate, the rollers are separated and the pusher member is moved by the ram 19 to engage the rear edge of the plate and push the plate until it abuts the stop 11. If two pusher members are provided they are moved independently until the plate engages the stop to accommodate unevenness in the rear edge of the plate. The rollers then close on to the plate or, if the plate is sufficiently far advanced, on to one limb 14 of an L-section arm 15 of the pusher member and drive the plate a desired distance through the shear for a further cut or cuts, the distance being determined by an adjustable measuring roller 21. A hold-down 7 may be provided instead of the stop 11 for locating the plate while the pushing member is moved into engagement with it. In alternative embodiments, two pairs of drive rollers, one of which is adjustable to accommodate plates of varying widths, are provided and a pusher member is associated with each. The pusher members are moved independently into engagement with the plate which is held by the hold-down 7 and then driven by motors (24) (Fig. 3, not shown) which through gearing also drive the rollers 5, 6. The pushing members are coupled during pushing movement. To prevent the plate moving forward after the pusher member has stopped, due to inertia, a gripper jaw operated electro-magnetically or by a thrust cylinder (Figs. 4 and 5, not shown), may be provided at the forward end of the or each arm 15.

Filed: 1974-05-24
Abstract: 1466730 Electrodialysis of waste sugarindustry liquors TECNECO SpA 24 May 1974 [15 June 1973] 23474/74 Heading C7B Waste solutions from the regeneration of ionexchange resins used to treat raw sugar liquor are  treated by electrodialysis in at least two cells having ion-exchange membranes whereby ionic and nonionic components thereof are segregated. The regenerating solution from an anionic resin, containing hydroxide, e.g. NH 4 OH, is electrodialyzed in the cathodic compartment of a cell with a cation-permeable membrane while an acidic, e.g. H 2 SO 4 , solution from regeneration of a cationic resin is similarly treated in the anodic compartment of a cell with an anion-selective membrane. The concentrated NH 4 OH and acid are recycled and the concentrated organic-containing remainders are combined, neutralized, subjected to reverse osmosis to remove pure water and finally dried, e.g. using the H2 and possibly O 2  generated during electrodialysis, with optional added methane, as heating fuel. To form a complete waste-treatment system, an NaCl solution from regeneration of sugar-decolorizing resins may be reverse-osmolyzed in two stages to recover NaCl, which is recycled, pure water and a salt and organic-containing residue which may either be combined with that mentioned above or subjected to combustion to recover NaCl using its own organic component as fuel. Finally the effluent from regenerating sugar decalcifying resins may be treated with NaOH and CO 2  to remove Mg and Ca, filtered, neutralized and reverse osmolyzed to recover NaCl, which is recycled, and pure water. In addition to acids, salts and bases, the following organic materials are stated to be possibly present: B-group vitamins, lysine, arginine, tyrosine, betaines, glutamic acid, aspartic acid, purines, pyrimides, a sugar fraction and oligomers.

Abstract: 334,347. Kronenberg, R. Aug. 2, 1929. Linear-dimension gauges. - In a measuring apparatus, particularly for rolled sheets, the deviations from a standard dimension are magnified and transmitted to a pointer, which, for more accurate readings, influences an auxiliary pointer indicating the deviations on a further enlarged scale. In addition, a continuous record is obtained on a moving strip of paper by a stylus connected to the main pointer. The sheets to be measured are passed between rollers 5, 19 of which the roller 5, mounted in a block 6, is adjustable by a screw-threaded bolt 13 operated bv a nut 14. When a standard sheet has been inserted and the roller 5 adjusted, the block 6 is clamped in position by a screw 17 engaging a pressure plate 18. The upper roller 19 is supported on a pin 20 mounted in a block 22 sliding in a casing 3 and prevented from rotation by a prism 23 secured to the casing. A spring 27 is held between a pressure plate 28 and a pressure block 26 mounted on a bolt 25 which is secured to the casing and passes through longitudinal slots 24 in the block 22. A member 29 has knife edges 30 on which is mounted a lever beam 31 carried on a shaft 33 with a knife edge 32, and a spring 34 held between the casing and the beam 31. The knife edges 30, 32 are out of vertical alignment, and movement of the block 22 is transmitted to a pointer 38, of which the end 39 moves over a scale 40. To obtain more accurate readings, an auxiliary pointer 42, pivoted at 43 and connected to the pointer 38 by an adjustable screw 44, moves over a secondary enlarged scale 41. The pointer 42 is held against the screw bolt 44 by a spring 45 or a counterpoise 46. To record the deviations, a drum 55, driven by gearing 48, 59, 50, 51 unwinds from a roll 56 a strip of paper, kept in contact with the drum by rollers 58 and a spring 59. A stylus 60, carried in a holder 61 and resiliently pressed against the paper by a spring 64 is operated directly from the main pointer by an adjustable bolt 62 against which a spring 63 holds the stylus holder. A guide 66, with lateral projections 67, retains the paper against displacement.
