Abstract: 211,659. Quicksafe Manufacturing Co., and Waller, R. H. Jan. 11, 1923. Opening by cutting.-A can-opener of the type employing a rotary cutter actuated simultaneously and in co-operation with a pair of rollers engaging the end bead on the inside and outside respectively, is so arranged that rotation of the operating handle in the reverse direction to that employed to open the can has the effect of disengaging the gears and enabling a fresh can to be placed in position for opening. In the form shown in Figs. 1 and 2, rotation of the crank 10 in a clockwise direction causes rotation of the circular cutter 17 and collar 16 and also of the co-operating roller 23, which engage respectively the outside and inside of the bead 24 on the end of a can. Reversal of the direction of movement causes gear wheel 11 to leave its engagement with wheel 12 and engage and move along a rack bar 27, the arm 7 carrying the cutter and collar turning on its pivot to permit this movement, which is constrained by a slot 14. Fig. 5 shows in perspective a modified construction the base-plate of which is adapted to be clamped to a table.

IPC: G09G3/04
Filed: 1967-01-09
Abstract: 1,188,211. Light modulators. INTERNATIONAL COMPUTERS Ltd. 27 Dec., 1967 [9 Jan., 1967], No. 1159/67. Heading H4F. [Also in Division G5] The coercivity of layer 2 varies with temperature, and it rotates the polarization of electromagnetic radiation in dependence on its magnetic state. Hence a 2-dimensional image may be stored in layer 2 by applying a heat pattern to its surface and reversing the polarity of a solenoid 4: only the heated areas will have their magnetic state switched. To read out the image, polarized radiation from a source 11-14 is caused to be transmitted through layer 2 and viewed through analyser 16. As described, the heat pattern may be applied by shining a beam of light 7 through a character plate 8 and on to layer 2; or the light pattern may be built up by a raster of scanning lines or by the selection of light spots in a matrix. Alternatively, the heat image is formed by squirting a heated (or cooled) fluid through a mask on to layer 2.
Patent GB-640543-A (GB)
Title: Improvements in or relating to the production of cellulose
IPC: D21C1/10
Filed: 1948-01-14
Abstract: The pentosan content of cellulosic material is reduced by impregnating the material with a dilute aqueous caustic alkali solution, lowering the temperature of the impregnated material to about -4 DEG  C. or lower (but not so low that the cellulosic material is dissolved), allowing the material to stand for a period, p  raising the temperature at least sufficiently to melt all the ice formed and subsequently heating the material with a dilute aqueous caustic alkali solution.  The cellulosic material may be a raw ligno-cellulosic material or a product derived therefrom by a chemical pulping process or resulting from a chemical pretreatment or a purification operation employed in connection with such a pulping process.  The process may thus be carried out before or after a sulphite, soda, or sulphate cook, a chlorination, or a process comprising a nitric acid treatment and a caustic alkali treatment. The period during which the caustic alkali solution remains in the frozen condition may be 1-5 hours. After heating to melt the ice, the solution containing extracted pentosans is removed from the cellulosic material, e.g. by pressing, filtration or washing.  The caustic alkali used may be of 2-5 per cent strength.  The mixture may be cooled to a temperature between -40 DEG  and -6 DEG  C.  The alkali freeze is followed by a boil with a dilute caustic alkali solution so as to remove still more of the pentosan content of the material.  For the alkali boil, a caustic alkali solution of below 5 per cent, e.g. 0.5-3.5 per cent, may be used.  The alkali boil may be followed by other treatments, e.g. with hot dilute alkali, cold and stronger alkali solution, chlorine water, hypochlorite, or chlorite. The pulp may be bleached between the alkali freeze and the alkali boil.  In the case of annual vegetable materials such as straw it is preferred to effect an alkali freeze treatment before the main pulping operation.  The material may be subjected to a prehydrolysis step using water under pressure or dilute sulphuric or hydrochloric acid.  The process may be applied to cotton linters, cereal straw, bamboo, spruce, beech, or poplar wood pulp.  The cellulose obtained may be used in the manufacture of cellulose esters and ethers and cellulose solutions, particularly for the production therefrom of artificial textile materials, coating compositions and lacquers.

Title: Improvements in or relating to fluid pressure operated valve mechanism
IPC: F16K31/34
Filed: 1954-01-15
Abstract: 752,559. Fluid-pressure servomotor-control systems. PARKER APPLIANCE CO. Jan. 15, 1954 [Jan. 16, 1953], No. 1177/54. Class 135. A float-controlled valve mechanism employed in the filling of tanks comprises an inlet valve closure member 22 carried by a movable wall 21 which forms part of a control chamber 26 for the valve, and the chamber 26 communicates with a restriction (e.g. the throat of a venturi 31) inserted in a conduit 27 open at its lower end 29 to the inflowing fluid upstream of valve 22 and leading past the control chamber to the upper part of the tank where its upper open end is controlled by a pilot valve 40 actuated by a float 42 in the tank. The valve 22 is loaded to the closed position by a spring 24. In operation, with valve 22 open, liquid enters the tank from a pipe line 15 and also flows through conduit 27 and out at the upper end thereof. The depression produced at the throat of the venturi due to flow through conduit 27 is communicated to chamber 26 so that inlet pressure can keep the valve open. When the tank is full, float 42 rises and closes pilot valve 40 to shut off flow through the passage, and the pressure in chamber 26 then rises sufficiently to close down valve 22. In a modification, two superposed diaphragms separated by the loading spring form two control chambers each of which communicates with a restriction in its own flow passage, and each passage is controlled by its own float operated valve.

Abstract: 660,038. Tyre valves. DUNLOP RUBBER CO., Ltd. Jan. 15, 1949 [Jan. 16, 1948; April 13, 1948; Nov. 10, 1948] Nos. 1179/49, 1180/49 and 1181/49. Class 135. A rubber tube connecting the inner tube of a pneumatic tyre with the inflation valve contains a flexible non-resilient reinforcement so that the tube will retain any bent configuration imposed upon it. In one form, the rubber tube 1, Fig. 1, which has a flange 3 vulcanised to the inner tube 4, has a reinforcing pipe 20, e.g. of malleable metal such as copper, &c. Additional fabric or metal reinforcement 2 is moulded within the tube, the exterior of which is protected by a wire helix 16. The valve 9 is attached to the tube 1 by screw-threaded engagement with a sleeve 6 at the end of the tube, a tight joint being obtained by a conical sleeve 11 forced between the tube 1 and the pipe 20 by engagement of its end 12 with the body of the valve 9. Overtightening of the valve on the sleeve 6 is prevented by engagement of a projection 18 with a slot 19. In a modification (not shown), the reinforcing pipe 20 is replaced by a wire disposed, with clearance, in the bore of the tube 1. The wire may have a groove, spiral or rectilinear, to permit the passage of air in the event of excessive bending of the tube 1, closing the clearance. Fig. 6 shows an alternative method of securing the rubber tube 1 to the valve and Fig. 7 illustrates means for detachably securing the tube 1 to the inner tube. Another method of attaching the tube 1 to the valve is shown in Fig. 8 in which a sleeve 35 having coarse, rounded, internal threads is first screwed on to the tube, after which a stepped conical extension 40 of the valve is pushed between the tube 1 and the reinforcing pipe 20 and a nut 42 is then screwed on to the sleeve 35 to secure the valve tightly in position. The valve may be secured to a fitting 48 by a nut 45. In a further construction (not shown), in which the tube 1 is fixed to the inner tube as in Fig. 1 and to the valve by means similar to that disclosed in Fig. 8, the bore of the tube 1 is lined by a wire helix which houses a flexible, non-resilient wire leaving a clearance for the passage of air.
