Title: Process and apparatus for electrodialyzing liquids
IPC: C13B20/18
Filed: 1955-04-26
Abstract: 792,623. Electrodialysis. IONICS, Inc. April 26, 1955 [May 6, 1954], No. 11970/55. Class 41. A method of changing the concentration of an electrolytic solution by passing it through the diluting chambers 15 of an electrodialysis unit comprising alternate concentrating chambers 13 and diluting chambers 15 defined between alternate anion- and cation-permeable membranes A, K, a further solution being passed through the concentrating chambers, comprises passing the two solutions in parallel through the chambers 13, 15 at rates which are controlled, e.g. by valves 32, 74, to keep the readings or pressure gauges 36, 78 equal, so as to maintain equal pressures on opposite faces of the membranes A, K, at any point thereof. Sea water, cane juice, glycerine or whey is delivered from a pipe 2 to the diluting chambers 15 by a pipe 38, returning by a pipe 40 to a tank 18 to be recirculated by a pump 30. Two modes of operation may be employed. In " batch " operation a cell 28 responsive to the conductivity of the liquid in pipe 40 closes a valve 20 and opens a valve 22 when a certain degree of dilution is achieved, a valve 14 being operated by a float in the tank 18 to admit fresh liquid. In " continuous recirculation " operation the valve 14 is held partially open, dilute liquid being continuously withdrawn at 19. Similar apparatus deals with the concentration stream entering at 50, and with an electrode stream, which may be an aqueous solution of sodium sulphate or dilute sulphuric acid, entering at 100. The pH value of the electrode stream may be maintained by introducing acid into a tank 118 corresponding to tank 18. If desired, a single source of liquid may be used for concentration and electrode, or electrode and dilution streams, or for all three streams, by means of pipes 42, 84. The membranes A, K are separated by baffles which define a tortuous path for the liquids. Specifications 702,002, [Group XXVI], 772,861 and 772,862 are referred to.

Title: Improvements in or relating to apparatus for severing a charge-of glass below a suction mould in glassware-forming machines
IPC: C03B7/10
Filed: 1932-04-27
Abstract: 385,827. Glass manufacture. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Europõischer Verband der Flaschenfabriken Ges.; 20, Breitestrasse, D³sseldorf, Ger- - many.) April 27, 1932, No. 12078. [Class 56.] Relates to a glasswareforming machine of the suction-gathering type in which the cut-off knife is operated by a spring, and consists in operating the knife by means of a compression spring which is stressed by means of a slide. The Figure shows one of the mouldcarrying arms of the machine in sectional elevation. The cut-off knife 13, which moves across the bottom of the parison mould 5, is secured to the lower end of a vertical rocking- shaft 14 which oscillates and reciprocates in a bearing 15 at the outer end of a bracket 16 extending from the frame 10. The knife 13 is alternately raised and lowered, in the usual way, by a bell crank 17 operated by a cam 22, and it is oscillated by a pinion 23 which is feathered in the shaft 14 and is engaged by a rack 25 connected to one end of a rod 26. The other end of the rod is secured to a slide 27 which is moved along a slideway 28 by a cam 30. Part of the cam is cut away, and in the cutting- position the slide 27 and the rod 26 are moved outwards by a spring 31 which is coiled on the rod 26 between a stop 32 and a cross-bar 33. The inward movement of the slide 27 compresses the spring 31 until the slide is engaged by a latch 40. At the appropriate time, the latch is released by a short cam 39 and the slide is moved rapidly outwards. The outward movement causes the blade 13 to swing rapidly across the bottom of the mould 5 and to cut through the cord of glass that trails from the mould. The rapid movement of the blade enables it to cut through the glass without coming into contact with the bottom of the mould. The cross-bar 33 is connected through springs to the slideway 28, and a cup 36 mounted on the bar co-operates with a piston 37 carried by the slide 27 to constitute a dashpot which cushions the movement of the slide under the influence of the spring 31.

Title: Rotogravure printing press and method of adjusting impression roller thereof
Inventor: BEHRINGER ALFRED CARL
IPC: B41F13/30
Filed: 1962-03-31
Abstract: 989,117. Printing machines. PUBLICATION CORPORATION. March 31, 1962, No. 12493/62. Heading B6C. The method of adjusting an impression roller 2, Fig. 4A, foreshortened at one end relative to a full length printing cylinder 1 of a rotogravure press including a pair of slidable end supports 6, Fig. 4B, for the roller movable to bring it into engagement with the cylinder, comprises the steps of moving the supports to bring the roller towards the cylinder and intercepting the end support at the foreshortened end of the roller at the position which the end support would occupy if it carried a full length roller of the same diameter. The interception may be effected by placing a shim 60 of the requisite thickness on the ledge 61 of the support slideway associated with the press side frame 6. Alternatively, the support may carry a screw member 63 adjustable to the required spacing through actuation of a manually operated worm gearing 68, 69. Each support may carry an adjustable screw member 63 the required spacing being obtained by appropriate rotation of either one or both worm gears. Each support is moved in its associated slideway 29, Fig. 5, by a spring-loaded threaded rod 21, which is vertically displaced through rotation of an inner threaded member 19 threadedly engaged with the rod 21 and rotated through a power driven worm gearing 15, 16. The spring loading on the support is increased when the roller 3 abuts the cylinder 1 through continued rotation of the worm 15 which causes the member 19 to move relatively upwardly thus compressing the spring 30 through engagement of the member 19 with a member 35 and an adjustable member 34. Such spring pressure is recorded on a dial 40 the adjustable member 34 actuating the necessary recording mechanism through linkage 41, 42, 45. A dial 39, disposed next to the dial 40, records the loading on the other support in order that an evening pressure along the length of the impression roller may be easily effected. Limit switches 54 and 56 are respectively used to control the downward movement of the associated slide block 6 at the desired compression of the spring 30 and to raise the block and relieve pressure between the roller and cylinder should the spring loading become too great. A hand controlled disengaging clutch is provided in the power drive to the worm 15 associated with the press side frame 5.
