Abstract: 907,663. Stretching. HYDRAULIK G.m.b.H. Nov. 26, 1958 [Nov. 28, 1957], No. 38200/58. Class 83 (4). Plate or sheet is stretched between two gripping devices each of which includes a plurality of separate adjacently disposed, clamping devices mounted across the frame member of the gripping device and supported thereon without the interposition of fluid under pressure, the clamping devices being separately adjustable, or arranged, so that the greater elongation normally given to the sides of the sheet, owing to the deforming under stress of the gripper frame, is corrected. A gripper frame 26 directly supports ten clamping devices 27- 36 which grip the end of a sheet 4 to be stretched. The frame 26 is moved, by rods 38 in pressure cylinders 37, away from similar means holding the other end of the sheet. During this stretching, stress causes the frame 26 to sag in the middle so that the sides of the sheet are stretched more than the middle. The stretching is therefore interrupted, the elongation at various points across the sheet is measured by devices 1 and recorded on dials 40, the clamping devices are adjusted accordingly, so that on continued movement of the frame 26 the outer clamping devices are closed last, and the stretching continued. The measuring devices 1 each comprise a fixed feeler 2 and a pivoted feeler 3 movement of which rocks a lever 5, which may control a rotary potentiometer 9. The device 1 is mounted on a rod 12 carried by a member 13 lifted by links 15, 16 pivoted to the frame 26 and rocked by a piston rack 19. The clamping devices may comprise gripping jaws 42 opened or closed by rods 43 moved simultaneously, the length of the rods of each jaw or pair of jaws being suitably adjusted by a tension lock 44 according to the readings on the dials 40. A modified form of clamping device, Fig. 4, includes jaws 52a opened or closed by wedges 50, 51 moved by cranks 55 rocked by a piston 57 controlled by valves 61, 62 and adjusted by wedges 53.

Filed: 1965-09-07
Abstract: <PICT:1108296/C6-C7/1> <PICT:1108296/C6-C7/2> A continuous or batchwise process for clarifying a sugar juice comprises liming the juice to a pH of 7 to 9 and phosphating the limed juice to effect precipitation of the impurities, coagulating the precipitate, which steps may be carried out at or above atmospheric pressure, subjecting the mixture to a reduced pressure (e.g. a vacuum or atmospheric pressure) to effect flotation of the coagulated precipitate and removing the coagulated precipitate from the surface of the clarified juice.  The sugar is crystallized from the juice and the precipitate is filtered, the filter cake being washed with water to extract sugar therefrom. The clarified juice may be subjected to the same clarifying process again but at an elevated temperature.  In the apparatus of Fig. 2 sugar juice treated with lime, phosphate and coagulant, is passed by pipe 33 into well 25 in drum 14.  Vacuum is applied to drum 14 via pipe 22. The juice is passed through slot 26 in well 25 to annular space 21, the precipitate being swept from the surface of the juice by scrapers 20 on rotating shaft 18, over weir 32 and discharged through outlet 31 connected to an extraction pump and the clarified juice being discharged through outlet 30 connected to an extraction pump.  The drum 14 is provided with viewing port 23 and vacuum gauge 24.  In another embodiment (Fig. 3) the treated juice is passed into a tank 34 in which there is a number of inverted extraction cups 36 with outlet pipes 37 through which the clear juice is discharged by gravity and the precipitate is withdrawn through the vacuum line 38 communicating with the top of the tank.

Abstract: 1,126,971. Simulation of electrolytic cells. REYNOLDS METALS CO. 8 Sept., 1965 [21 Sept., 1964], No. 38284/65. Heading G4G. [Also in Division C7] In operating a multiple anode electrolytic reduction cell for the production of free metal, e.g. aluminium, there is calculated for each carbon anode block the size of a pseudo-area corresponding to the effective conductive area of that block and the vertical position of each anode is adjusted so that the current through each anode bears the same relation to the total current as the pseudo-area of each anode bears to the sum of all the pseudoareas. For this purpose electrical analogue models are prepared by drawing to scale (see Fig. 2, not shown) on thin electrically conductive paper separate outlines of the cell taken in two perpendicular vertical planes and forming conducting areas, e.g. with silver paint, representing the anodes and cathode. By measuring the separate anode currents flowing across the model on applying a known voltage between cathode and anodes a dimension proportional to the resistance for each anode path is determined, the product of the two dimensions for the same anode determined from the models representing the pseudo area for that anode:

A method of forming a laminate comprises impressing a substantially regular indentation pattern into a surface of a lamina so that in bounding the lamina to another lamina under pressure there are regions of locally increased pressure corresponding to the indentation pattern. In the example given a printed circuit board comprising a conductor layer of nickel foil, and a substrate of polyethylene terephthalate, is formed by arranging the foil and substrate to sandwich a layer of thermosetting resin, placing a piece of steel gauze in contact with the outer surface of the substrate, placing the assembly between two steel platens, and compressing the whole in a heating press until the resin has at least partially set. On removal from the press the steel gauze, which has impressed the indentation pattern in the substrate, is removed from the laminate. Instead of using a separate gauze the indentation pattern can be formed in the steel platen which backs the substrate.
