Title: Cathodes for electron discharge devices and alloys therefor
IPC: H01J1/146
Filed: 1940-02-01
Abstract: 538,479. Alloys. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 1, 1940, No. 1957. Convention date, Feb. 1, 1939. Addition to 534,154.

Patent GB-1087771-A (GB)
Title: A process for producing hydrogen sulphide and calcium carbonate from a solid containing calcium sulphide produced in a gas desulphurization process
IPC: B01D53/52
Filed: 1965-01-15
Abstract: A solid containing calcium and magnesium oxides, e.g. calcined natural dolomite, CaO.MgO, which has been used to absorb sulphur from a gas, forming CaS.MgO, is regenerated by reacting with carbon dioxide and steam at a pressure of not less than 4 atmospheres and a temperature of at least 450 DEG  F. so as to give CaCO3.MgO and H2S, preferably in a reducing atmosphere of H2, CO.  The CaS.MgO may be reacted with CO2 before reacting with CO2 and steam to convert any CaO remaining from the desulphurization to CaCO3, the temperature and partial steam pressure of the subsequent reaction with CO2, steam being adjusted to form Ca(OH)2 therefrom.  The CaCO3.MgO may be calcined to CaO.MgO preferably in a reducing atmosphere to prevent oxidation of any sulphide present to sulphate, and the regenerated double oxide may be re-used for desulphurization of the gas.  The steps may all be carried out in fluidized beds.
Patent GB-624471-A (GB)
Title: Improvements in or relating to the manufacture of films and foils
IPC: B29C48/08
Filed: 1947-01-22
Abstract: Apparatus for casting films and foils comprises an endless supporting band, guides for the band to cause it to travel in a spiral path, means for directing the band laterally, at or beyond the ends of the spiral path, along another path transverse thereto and back again, means for casting film or foil on the band before entry to the spiral path, and means for stripping dried film or foil off the band at or beyond the exit end of the spiral path. Guide bars set diagonally across the direction of advance of the supporting band may be provided for directing the band laterally along a transverse path. The supporting band may be housed over its spiral path in a casing through which air is circulated.  The supporting band may be of non-absorbent paper, coated paper, or thin metal.  The apparatus may be used for casting films of cellulose derivatives, polyvinyl compounds, rubber-like substances, or other film-forming substances. As shown in Figs. 1, 2, the band 11 runs in an endless path over a number of rollers.  A solution of plastic material in a volatile solvent is cast on the band from hopper 14.  From the casting point, the band 11 passes horizontally into the drying chamber 15 and over and round guide bar 16 which is set diagonally to the line of advance of the band.  The band is thus turned through <PICT:0624471/IV (a)/1> <PICT:0624471/IV (a)/2> <PICT:0624471/IV (a)/3> <PICT:0624471/IV (a)/4> 90 degrees, and it is then led in a spiral path around rollers 17. From the outer end of the spiral, the band passes through slot 18 in the wall of chamber 15 to a second diagonally-placed guide bar 20 which turns it again through 90 degrees into a path parallel with and immediately beneath that in which it approaches the spiral portion. The dry film is stripped from the band by means of a knife 27 and is wound on roller 26.  The diagonal guide bars 16, 20 are highly polished and chromium plated to reduce friction. They are fixed to the machine frame by means of brackets constructed to allow for fine adjustment of the angle at which the bars are set and cut-away or shaped so as to avoid fouling by the travelling band.  To ensure proper positioning of band 11 as it passes over roller 12, a horizontal bar 33 with guide rollers 34, 35 and springs 36, 37 may be provided as shown in Fig. 5.  If desired, the casing 15 may have ribs extending between the turns of the spiral portion of the band 11 so as to ensure that the drying air does not pass directly from the inlet to the outlet. The stripped film may pass through a further drying chamber before being wound up.  An alternative arrangement for coating the band with film material is shown in Fig. 8.  The band 11 passes between the nip of roller 60 and the adjustable pressure roller 61 and then over a convex apron 67 to the pouring hopper 68. Roller 60 is driven by a belt 64 from pulley 65 on shaft 66, which also carries a supporting roller over which passes the coated band 11. Specification 428,663 is referred to.

Abstract: 254,759. Marks, E. C. R., (Universal Engineering Corporation). Jan. 26, 1925. Cam-actuated pumps ; stroke, varying. - In hydraulic apparatus for operating a broaching machine &c. of the kind comprising a pump supplying pressure fluid alternately to opposite ends of an operating cylinder, and in which means are provided to compensate for the different amounts of liquid forced into or out of the cylinder ends owing to the presence of the piston-rod in one end, the compensating liquid is contained in a reservoir 8 which has a permanent open connection with the casing 27 of the pump feeding the operating cylinder 4. The liquid is supplied alternately to ports 5, 6 by the pump 27, which is driven by a motor 25 and may be of the kind described in Specification 13894/07 comprising a rotary swash-plate 31 mounted in a tilting-box 31<1> which may be adjusted to reverse the pump or vary its output. The tilting-box is controlled bv a hand-lever 150 connected bv links 141 - - 149 to a rod 108 which actuates the control plunger 63 through links 101 - - 106 and a valve 76 sliding in a cylinder 68 screwed to the plunger 63. When the valve 76 moves down, pressure liquid from the delivery side of the pump passes from a pipe 89 through a passage 77 and ports 79, 71 to the upper side of a piston 72 fixed to sleeve 68 and forces the piston, sleeve, and plunger 63 down to reverse the box 31. When the machine is to be reversed again, the lever 150 is pulled in the opposite direction, raising the valve 76 and allowing pressure liquid to pass through the passage 77 and ports 80, 70 to the under side of the piston 72. which then moves up and raises the sleeve 68 and plunger 73, the liquid above the piston 72 escaping through the port 71 and passages 84, 78, 69 into the pump casing. In another form, the hydraulic relay 63, 76 is replaced by a direct mechanical connection between the rod 108 and the stroke-control means, said connection comprising a toothed sector and a pinion.

Abstract: 388,913. Sheet-delivery apparatus. BEEVERS, A., Swinton Row, Edinburgh. Jan. 27, 1932, No. 2455. [Class 100 (i).] Sheet-delivery apparatus particularly for stop-cylinder printing-machines comprises a plurality of travelling frames upon which the printed sheets are received, each frame being subjected to an abrupt change in its direction of travel whereby the sheet carried thereby is delivered. The frames 7 consist of flexible metal tapes and are carried by endless chains 1 passing over small sprocket-wheels 2, 3, 4, 9, 10, and the sheets are dropped on the frames from the delivery-cylinder D by rotating grippers in the usual way. As each frame 7 passes over the sprocket-wheel 9 it is given an abrupt change of direction and the sheet thereon is projected on to a reciprocating tape-carriage 11 which deposits the sheet on to a delivery table E. A roller may be mounted at the leading edge of the carriage 11 so as to facilitate the delivery of the sheets. Specifications 3677/10, 29258/10, and 14684/12, [all in Class 100 (i), Feeding and delivering webs, &c.], are referred to.

Class 98(2) For continuous gas development as of diazotype papers, ammonia from reservoir 29 through pipe 30 is vaporized in trough 16 of storage chamber 3, and is impelled therefrom by centrifugal pump 6 into delivery chamber 4 and through a slot 8 of sloping lower wall 14 of the latter into a developing chamber 9 of tapering shape, and which is formed by this wall 14 and the surface of an endless conveyer blanket 11 supported on driving rollers 12 mounted within a casing 10. Curved bottom surface of storage chamber 3 is provided with holes so that the developing vapours from chamber 9 may re-enter chamber 3 for re-circulation through chambers 4 and 9. Prints for development are fed through an inlet 27 between the blanket 11 and a forward portion 26 of the bottom surface of delivery chamber 4 adjacent to the slot 8, and are conveyed leftward to a second endless conveyer blanket 17 which may be driven in either direction to catch the paper as its edge begins to curl. on emerging from the development chamber 9, and deliver the paper at outlet 18 or 19. Heating means may be provided in chamber 3, chamber 4 or pump casing 5, and an advantage of the invention is that a rapid stream of uniform vapour mixture can be directed through the slot 8 at an angle to the direction of feed of the paper, and at any desired velocity according to the speed of the pump.
