Title: Improvements relating to the regeneration of water-softening materials
IPC: B01J49/00
Filed: 1957-03-18
Abstract: Polystyrene base exchange resins, which have been used for softening water supplied to one or more evaporators and/or boilers, are regenerated by contact with blowdown water from the evaporators and/or boilers, so that all the sodium and potassium ions used for the regeneration are derived either from the raw water or from the polystyrene base exchange resin.  The water which is softened with the aid of the resin may be subjected to a preliminary treatment with lime in order to effect a partial softening by removal of bicarbonate ions.  In an example the polystyrene base exchange resin employed is "Zeokarb 225" (the word "Zeokarb" being a Registered Trade Mark). Specification 521,112 is referred to.

Title: Improvements in or relating to methods of forming luminescent screens coated with thin films of organic material
IPC: H01J29/28
Filed: 1956-03-21
Abstract: 801,067. Luminescent screens. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 21, 1956 [March 24, 1955], No. 8829/56. Class 39(1). A method of forming a luminescent screen, e.g., for a cathode ray tube or an electron microscope, coated with a thin film of organic material includes the steps of settling luminescent material in an aqueous alkaline settling bed having a pH value greater than 9À5 and containing in solution potassium and/or sodium silicate and at least one alkaline compound, after the luminescent material has settled adding an amount of acidifying agent calculated to reduce the pH value of the settling bed to a value between 5 and 8À5, e.g., about 7, providing on the acidified settling bed a solution of the organic material having a specific gravity lower than that of the settling bed, and thereafter removing the settling bed. The luminescent material may be settled as a suspension in the solution of potassium and/or sodium silicate. The alkaline compounds are an alkali metal compound, an alkaline-earth metal compound or an ammonium salt, e.g., potassium sulphate, barium nitrate, calcium acetate or ammonium sulphate. The pH value is reduced to a value between 5 and 8À5 by adding to the settling bed an acid, e.g., phosphoric acid, or acid reacting salts, e.g., sodium di-hydrogen phosphate. The organic film materials may be nitro-cellulose or esters of polymetacrylic acid. Solvents for these materials may be butyl acetate, ethyl acetate or mixtures thereof. Softening agents may be added, e.g., dibutylphthalate. Aluminium may be provided by evaporation on the organic film which may subsequently be removed by heating. A portion of the settling bed can be removed after the settling of the luminescent material, whereafter the remaining portion is acidified until its pH value is reduced to between 5 and 8À5. The solution of the organic material can contain more organic material than is necessary for forming the film and after this solution has been provided the settling bed and the solution of organic material floating thereon are decanted in such manner that the solution of organic material passes along the luminescent screen leaving thereon a thin film. of the solution from which the solvent is subsequently evaporated. Alternatively the solution of the organic material can contain exactly the amount of organic material required for forming the film, the solvent being evaporated after the solution has been provided on the settling bed, so that a solid film of organic material floating on the settling bed is formed, whereafter the settling bed is removed in such manner that the film is deposited on the luminescent screen.

Title: Improved article gauging apparatus
IPC: B07C5/12
Filed: 1957-03-19
Abstract: 852,115. Sorting by plug gauging. OWENS-ILLINOIS GLASS CO. March 19, 1957 [April 16, 1956], No. 8924/57. Class 106 (2). [Also in Groups XXIV and XXX] Gauging and sorting apparatus comprises a gauging plug 21 reciprocatable in timed sequence between a withdrawn position, wherein it is dissociated from a bottle 16 to be gauged, and a projected position, wherein it is in bottle gauging relationship, and pusher bar 26 which is automatically actuated to reject a bottle when the timed sequence is interrupted by the plug 21 being prevented from attaining the projected position. Conveying, spacing, arresting and ejecting. Bottles 16 carried on a conveyer belt 15 are guided by an adjustable rail 31 into engagement with a feed worm 18 which spaces them for successive presentation to a gauging station 17 where each is momentarily arrested by a projecting plate 38 rotating with the worm 18. The bottles are then carried by the belt past an ejector 26 actuated by a motor 25 which operates only when the gauging operation has sensed a faulty bottle. The motor M and worm 18 are mounted on a base 30 which can be adjusted about a vertical post 39 to accommodate the feed to different-sized bottles and one of nine speeds of rotation can be selected for the worm 18 through change-gear mechanism (see Group XXIV). Gauging. While each bottle is arrested by the plate 38 at the gauging station 17, a plug gauge 21, Fig. 4, on a rod 48 is lowered into its neck and returned to initial position by the piston shaft 52 of a pneumatic motor 49 cyclically controlled from a cam 75 on the shaft 28. Since the plug gauge 21 cannot pass an obstructed bottle neck, lost motion is provided between the rod 48 and shaft 52 by passing the rod 48 freely through the shaft 52 and connecting a rod 56 and a tube 58 in which it slides to the shaft 52 and rod 48 respectively. The tube 58 and rod 48 rest on a collar 70 of the shaft 52 and descend with the piston, unless an obstruction in the bottle neck supports their weight while the piston shaft 52 descends to the bottom of its stroke, being picked up again and lifted to initial position during the upward stroke. The tube 58 carries two soft iron armatures 63, 64 which register with a magnetic pick-up 65 at the top and bottom of a full stroke of the tube 58 to pass a voltage to an electronic control circuit, the armature 64 failing- to register upon a restricted stroke of the tube 58 due to a faulty bottle being gauged. Electronic control of ejector motor. So long as good bottles are gauged, voltage pulses from the pick-up 65 keep a condenser sufficiently charged. to prevent a thyratron from firing. When a faulty bottle prevents the armature 64 from reaching operative position, the condenser will discharge to a low enough voltage to allow the thyratron to conduct and energize a relay, thereby operating the ejector motor 25, which at the end of its stroke opens a switch to deenergize the relay and return the motor to normal position, whilst restoring the control circuit to initial status.

IPC: H01M4/68
Filed: 1956-03-22
Abstract: 797,404. Batteries. HERMANN, F. March 22, 1956 [March 24, 1955], No. 9038/56. Class 53. The carrier of an electrode for a primary or secondary battery consists of a foamed synthetic plastic material, the active material in finely divided form being held within the bubbles of the foam and the intercommunicating pores between the bubbles being smaller than the particles of active material. The diameter of the foam bubbles is preferably 0.1-0.5 mm. and the foamed material may be foamed polyethylene or polystyrene or material known under the Registered Trade Mark " Moltopren ". The active material can be introduced into the bubbles by immersing the carrier in a water suspension of the active material, e.g. lead dioxide, or by spraying the carrier with such a, suspension under vacuum or, if the pores are sufficiently large, by shaking with dry powdered active material. The filling may be assisted by electrophoresis. The filled carrier is then heated in a mould with movable walls to a temperature approaching the plastic range of the synthetic material and is compressed from at least two sides until the pores contract sufficiently to retain the active material. Alternatively the bubbles can be filled with a solution of a salt of the active material and the salt then reduced. Current collector can be embedded in the carrier during the porereduction stage by hot-pressing two half-plates with the collecting grid between them. Alternatively filled carriers can be forced into a collecting grid.
