Title: Improvements in and relating to liquid dispensers
IPC: B67D1/00
Filed: 1936-05-11
Abstract: 472,853. Delivering measured quantities of liquids. ALLEN, H. C. May 11, 1936, No. 13316. [Class 106 (v)] In a drink dispenser comprising a supply tank 6 in which liquid is maintained at a definite pressure, means for transferring liquid from the tank to a measuring chamber 12 and a relief valve controlling a passage from the chamber to above the liquid level of the tank, the orifice controlled by the relief valve is at such a position at or near the top of the chamber that the latter can be substantially completely filled. In the form shown, two measuring chambers are provided each being connected with the tank 6 by a pipe 15 and inlet valve 17 and with the upper part of the tank by a pipe 18 and relief valve 20 and having also a discharge valve 22 and an air inlet valve 25. The valves 17 and 22 are operated by fingers 26 extending from a rockshaft 10 and in turn operate the valves 20 and 25. The valves of the other chamber are operated so that one chamber is filling while the other is discharging. Liquid is supplied to the tank under pressure through a feed pipe 30 and float-operated valve 31. Gas under pressure may be admitted through a pipe 34 and pipes 36 or 48, The pipe 48 leads directly to the top of the tank and is controlled by a valve 47 operated by a cam 59 on a rock-shaft 56. The other pipe 36 communicates with the top of the tank through a valve 37 kept open by a float 38 when the minimum quantity of liquid is in the tank and through a valve 43 controlled by a diaphragm 45 so as to close when the required pressure is reached. An air relief pipe 51 is controlled at the top by a valve 52 adapted to be closed by a float 53 when the minimum liquid reserve is in the tank and at the bottom by a valve 54 operable from the rock-shaft 56. The shaft 56 also controls a valve 33 in a passage 32 communicating between the feed pipe 30 and the bottom of the tank. In operation, liquid and then gas are admitted to the tank until cut off by their respective floatcontrolled valves and the measured quantities may then be delivered. During slack periods the liquid may be returned to the main supply by rocking the shaft 56 to operate the valves 54, 47 and 33 so as to close the air relief pipe 51, admit pressure gas through the pipe 48 and connect the bottom of the tank with the feed pipe 30. When the shaft 56 is returned, the gas pressure is relieved through the pipe 51. The shaft 10 is associated with stop mechanism for ensuring that the operating lever 11 shall not be turned to one side, back to normal and then again to the same side.

Title: Improvements in or relating to electric secondary batteries of the so-called dry type
IPC: H01M10/12
Filed: 1942-09-28
Abstract: 561,056. Galvanic batteries. FULLER, L., and SUDLOW, E. W. Sept. 28, 1942, No. 13563: [Class 53] A lead-acid accumulator of the " dry " type, in which all the space in the container which is not occupied by the electrodes is filled with porous separating material. to form a porous block in which the whole of the electrolyte is absorbed, is characterized by the fact that either the porosity factor of the whole block comprising the electrodes and separating material, or the porosity factor of either the positive or negative electrode, or of both electrodes, is at least 50 per cent. The porosity factor is the ratio of the total free space within the mass to the total volume of the mass. By making the electrodes sufficiently porous substantially the whole of the active material may be used efficiently with little more than the theoretical minimum quantity of acid ; the rise in resistance of the battery during discharge is diminished, so improving the voltage characteristic ; the discharge rate may be increased; and " choking " of the active material by sulphate is diminished. The desired porosity may be obtained by mixing a salt with the electrode material which dissolves out when the pasted plates are formed leaving pores. Alternatively, particles of porous filling material may be used and remain in the plates, for example powdered ceramic, 'aluminium oxide or silicate, active carbon black or charcoal, or natural or synthetic fibrous material. Examples of pasting mixtures for negative electrodes containing carbon black, asbestos fibres, or aluminium oxide, and having porosities of from 40 to 60 per cent are given. A pasting mixture for positive electrodes containing asbestos fibre, and having a porosity factor of 50 per cent, and another in which a porosity of 60 to 70 per cent is obtained by the formation of a relatively large amount of sulphate in the material, are also given. The porous separating material may be made as described in Specification 537,377, [Group V], of glass wool consolidated by a mixture of kieselguhr and a binding agent and compressed, the porosity varying between 50 and 80 per cent. The electrodes may be assembled in the accumulator prior to forming them, as described in Specification 550,334. Specifications 432,775, 506,062 and 540,591 are also referred to.

Abstract: 794,205. Making asbestos-cement pipes. ETERNIT SOC. PER AZIONI. May 11, 1955 [June 7, 1954], No. 13646/55. Class 87(2). An asbestos-cement pipe with a socket end is formed by placing tubular members 69, 66 or in modifications, Figs. 4 and 5 (not shown) a single, shaped, tubular member on an end of a pipe and then pressing the whole to take up the shape shown by the line 81 in Fig. 3. To apply the pressure, the assembly is mounted on a head 19 and rubber ring 28 which are moved by a piston 34 and rod 20 to an outer position (not shown) outside the plate 3. The head is then returned and half moulds 5 clamped around the member 69. Pressure is applied to a chamber 15 to cause a sleeve 11 to lock the moulds 5 in position. A piston rod 31 then acts through spring 30 to force a piston 29 against the ring 28 which bulges outwardly against the inner surface of the pipe. The head 19 is also moved to the right to compress the material against the inclined surface 26 to form the surface 81. Immediately afterwards, fluid is supplied to a piston 52, the rod 51 of which acts on an abutment 49 on the rod 20 to apply a strong compression to the material by means of the head 19. Simultaneously, fluid is supplied to the piston 59 to cause an annular edge 83 to press the edge 84 of the member 69. To remove the completed pipe the pistons 82 and 52 are moved back, moving the piston rods 20, 31 to the left and right, respectively, moving the sleeve 11 to the left to free the moulds 5 which are then moved apart, and then moving the head 19 to the right until the finished pipe is clear of the plate 3.

Abstract: 778,004. Electric incandescent lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 13, 1955 [May 15, 1954], No. 13898/55. Class 39(2)  Getter material is applied to the filament of an electric incandescent lamp after the ends of the filament have been secured in hooks at the ends of the leading-in wires and before the intermediate parts of the filament have been secured in the eyelets of filament supporting wires. Fig. 1a shows an incomplete lamp mount with a filament 11 suspended from leading-in wires 7 and 8 with its ends clamped within hooks 9. 10 formed at the ends of the said wires. the filament thereby hanging downwardly so that the greater portion of it can be immersed in a solution or suspension of a getter without immersing the hooks 9 and 10. The getter material is contained in a vessel which can be raised and lowered relative to a holder in which the mount is carried. The mount is subsequently completed by forming a button on the lower end of the glass stem 6, inserting filament supporting wires radially into the button, and locating the filament within eyelets at the outer ends of the radial wires. In a modification the bottom of the downwardly extending filainent loop is grasped by a hook 13 on the end of a holder 14 and swung around into a horizontal plane, as shown in Fig. 4, in which position the filament 11 is contacted by getter material 21 on a platform 17 carried by a vertically reciprocating rod 16. The platform is so dimensioned that the filament clamping hooks 9 and 10 (the latter not shown) do not touch the getter material. The getter employed for gas-filled and vacuum lamps may consist of phosphorus, together with cryolite or a fluorine compound for the purpose of avoiding blackening of the lamp.

Patent GB-614639-A (GB)
Title: Improvements in electrical apparatus for performing arithmetical calculations
IPC: G06F7/44
Filed: 1946-05-08
Abstract: 614,639. Locking switches; electromagnetic switches. VERNEAUX, J. E. P. May 8, 1946, Nos. 13919 and 13920. Convention dates, Oct. 4, 1943 and Sept. 25, 1944. [Class 38 (v)] [Also in Group XIX] Locking switches used in electrical calculating apparatus (see Group XIX) include a type in which a plurality of solenoids have common latching means, whereby the energization of any one solenoid causes previously latched solenoids to be released, leaving only the last energized solenoid in latched condition. Another type comprises a solenoid-operated twoposition switch ; a system of contacts assumes two positions alternately after each energization of the solenoid. In one latching arrangement, a row of solenoids A, &c., Fig. 12, having plungers 525 spring-urged to the deenergized position, have pins 527 co-operating with cam slots 528 in a common plate 529 urged to the right by a spring 527 attached to a bell-crank 525, pivoted to the plate at 534 and to a fixed pin 532. The solenoid A is shown in the latched (energized) position. When a solenoid B in the unlatched (lower) position is energized, its pin 527 drives the plate 529 to the left, releasing any previously latched solenoids to be returned by springs 526. The plate 529 returns when the pin 527 reaches upper position and holds the pin there after de-energization of the solenoid. In another embodiment, the solenoid plunger 525, Fig. 14, is pulled downwards, against spring 570, upon energization of the solenoid, and a projection 551 passes under a similar projection 546 on a spring-urged plunger 545. Upon de-energization of the solenoid the plunger 535 is lifted by the stronger spring 570 and, through a pin 527 and cam slot 528, the plate 529 common to a row of plungers, releases any other plunger 545 which may be in the latched (up) position. As the pivoted end 552 of the solenoid plunger reaches a fixed pin 553 it is rocked clear of the plunger 545 leaving the latter in the latched position. The two-position switch comprises a cam plate 542, Fig. 12a, pivoted about a shaft 541 which actuates the electrical contacts, and rocked alternately to left and right by the plunger 525 of a solenoid C. An arm 544 pivoted to the plunger 525 carries a pin 543 which, as the solenoid is operated, is lifted out of one notch of the cam plate 542 and, subsequently, riding on the sloping edge 542a, is forced to a central position so that, when descending, it enters the opposite notch of the cam and so rocks the latter over into the other position.
