Title: Process for the separation of volatilised liquids from gaseous mixtures
IPC: B01D53/02
Filed: 1935-09-07
Abstract: Fully esterified cellulose esters of organic acids, particularly fibrous cellulose tri-acetate, are employed for the adsorption of vapours from gaseous mixtures.  The process may be applied in the recovery of volatile solvents evaporated from cellulose ester solutions in the manufacture of artificial silk, films, coated or impregnated fabrics.  The solvents recovered may be acetone, methylene chloride, or tetrachlorethane.  Mixtures of air and vapour may be passed over the superficially extended cellulose triacetate. The mixture of air and solvent vapour obtained by evaporation of the cellulose ester solution may be subjected first to ordinary condensation to remove the greater part of the solvent, and the remaining solvent vapour may then be completely removed from the air by adsorption in the fully esterified cellulose ester.  Further cellulose ester solution may be obtained by utilizing the material used as adsorbent and containing adsorbed solvent.  The cellulose ester may be used alone or mixed with a plasticizer or other substance which increases its adsorptive properties.  The Provisional Specification refers also to the use of cellulose esters in the removal of traces of impurities from carbon dioxide.ALSO:Fully esterified cellulose esters of organic acids, particularly fibrous cellulose tri-acetate are used for the adsorption of vapours from gaseous mixtures.

Title: Improvements in or relating to coupling devices for use in the production, amplification or reception of ultra-short waves
IPC: H01Q13/00
Filed: 1937-09-14
Abstract: 507,473. Electric resonators; aerials. BORMANN, 0. Sept. 14, 1937, No. 25012 Convention date, Sept. 15, 1936. [Classes 40 (iii) and 40 (v)] A transmission line 2, Fig. 10, of the coaxialconductor type is coupled to a conducting tube 3, which comprises a hollow resonator of the dielectric-guide type, by means of slots 1 cut perpendicular to the current-paths in the conductive walls of the transmission line 2 and conducting tube 3. The waves may be standing or travelling waves. The tube 3 may be evacuated or may contain air or other gas, or a liquid or solid dielectric. Its ends may be open or-closed. The slots 1 may be open or sealed with insulating material, and may be of adjustable width. One mode of oscillation for standing waves is shown in Fig. 3, where the lines of electric field E are closed circles with centres on the axis ZZ, while the lines of magnetic field are curves H embracing them. Various other modes of oscillation are described, Figs. 4 to 7 (not shown). In the mode shown in Fig. 3, oscillatory currents flow in the curved surface S of the cylinder 3, parallel to the circles shown in section at E, and the coupling slot 1, Fig. 10, is cut so as to be transverse to the lines of current flow. Fig. 8 shows one mode of oscillation in a resonator 2 of the coaxial transmission-line type, in which the lines of electric field and current-flow are denoted by arrows E, and there are a current mode at the middle XX of the resonator and current antinodes at its ends. ' The slot 1, Fig. 10, is accordingly transverse to the current path in the transmission line 2 as well as to that in the conducting tube 3, and serves for coupling one to the other by flow of current over the edges of the slot. The waves may be stationary or travelling waves, or a mixture of both types. They may travel down a coupling tube 4, Fig. 11, which is fed through a coaxial line (not shown), and be emitted into space by a set of parallel radiators 8 coupled to the tube 4 through slots 1, which may be of progressively increasing size, so that they may radiate equal outputs of energy. The invention may be used, Fig. 12 (not shown), for coupling radiators such as 8 to a feeder formed as a pair of coaxial cylinders, and again for coupling the feeder to a dielectric guide which in turn is coupled to a valve formed as a pair of coaxial cylinders. Specifications 429,863, 449,920, 452,490, 452,761, 493,695, and 494,835 are referred to.

Title: Improvements in or relating to control systems for hydraulic turbines
Inventor: KERENSKY GLEB
IPC: F03B15/08
Filed: 1963-06-24
Abstract: 1,042,404. Hydraulic turbines. ENGLISH ELECTRIC Co. Ltd. June 23, 1964 [June 24, 1963], No. 25017/63. Heading FIT. [Also in Division G3] A control system for an hydraulic turbine comprises a governor 11, Fig. I, connected by a link 22 to a control ring 21 which adjusts the guide vanes to reduce the flow to the turbine runner with increase of speed and vice-versa. The control ring 21 is also connected to the piston 23 of a dashpot 19 whose cylinder is connected to a lever 17 which operates a relief valve 14. The relief valve controls the outlet of a pipe 15 connected to the penstock 12 and is of such a size that it can only pass a small proportion of the flow which can pass through the turbine runner when the vanes are in their maximum flow position. As shown, the valve 14 is loaded to a closed position by a spring 16. In operation, when the governor moves the ring 21 in an anticlockwise direction to close the vanes, the relief valve is also moved to the open position after which the dashpot collapses to allow further movement of the ring 21. After the governor has completed the necessary movement of the ring 21, the spring 16 moves the valve 14 to its closed position under the control of the dashpot bleed. The relief valve may be loaded to the open position so that it is closed on movement of the ring 21 to open the vanes or the valve 14 may be loaded to an intermediate position and thus opens fully or closes when the vanes are closed or opened. The governor 11 comprises a piston valve moved by centrifugal weights to control the supply and exhaust of fluid to the opposite sides of a vane to cause rotation of an arm connected to the link 22. In a modification, the control ring 21 is connected to a large piston 52, Fig. 4 (not shown) the movement of which causes a magnified movement of a smaller cylinder 56 which may be connected directly to the relief valve lever 67 or to the control valve 59 of a servomotor 57 as described in Specification 937,653. After the relief valve 14 has been moved, the valves 71, 72 allow the dashpot to collapse to permit further movement of the control ring 21. The pressure in a pipe 55 can also act on a throttle device 74 when the pressure rises at the end of the movement of the relief valve. The throttle device is arranged in one of the feed lines to the vane of the governor and thus acts to damp the governor movement after movement of the relief valve.

IPC: B21D53/50
Filed: 1932-09-09
Abstract: 407,051. Sliding - clasp fastenings. COX, L., 94, Gravelly Hill, Birmingham, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. Sept. 9, 1932, No. 25178. [Class 44.] The fastener elements and sliders for fastenings of the type in which two stringers are connected by the interlocking of fastener elements brought into engagement by the slider are made of malleable iron coated with non-rusting material such as rubber, resin, paint, or nickel plating. For the elements a bar of round iron wire is swaged at intervals so that when pressed flat it forms a series of pear-shaped blanks out of which the elements are stamped. Also for the sliders a bar of round iron wire is swaged at intervals so that when pressed flat it forms a series of 8-shaped blanks which are then separated and their edges bent up and trimmed and the blanks folded over at the neck to form the guide channels. Rough edges are removed by tumbling the sliders and elements in a barrel with sand and water. After washing and drying, the coating is applied preferably electrolytically or by dipping with subsequent heating.

Title: Improvements in or relating to Devices for Controlling and Adjusting the Tension of a Web Fed from a Roll
IPC: B65H23/188
Filed: 1967-06-01
Abstract: 1,153,812. Feeding webs. CHAMBON Ltd. 1 June, 1967 [7 June, 1966], No. 25257/67. Heading B8R. A tension control device for a web 1 passing from a supply roll 2, through a first pair of feed rollers 3, 4 and a second pair of feed rollers 5, 6, comprises a looping roller 9 between a pair of rollers 7 and 8, the looping roller 9 being connected to a relatively heavy cylinder 13 adapted to roll on an inclined plane 14. The angle of inclination of the plane 14 is varied either manually or automatically, so as to vary the force exerted on the roller 9 by the cylinder 13, thereby varying the web tension. Feed rollers 3 and 4 are driven by a power shaft 21, via a differential 22, the output of which is controlled by a servomotor 23. The motor 23 is in turn controlled by photo-electric cells 24 and 25 detecting the length of the web loop formed by the roller 9. In the embodiment illustrated, the rollers 5 and 6 are printing cylinders, and registration marks m, on the pre-printed web are compared with a registration mark m 2  on the printing cylinder 5 by photo-electric cells 35 and 36. The error signal produced is used to control firstly the differential gear 32 driving the cylinder 5, and secondly the angle of indication of the plane 14 by means of a servomotor 15 to which energizing current is supplied from an integrating unit 39 connected to the output of a comparator gate 37. As an alternative, the looping roller 9 may be positioned above rollers 8 and 7 (Fig. 2). As a further alternative, the cylinder 13 is connected by a link (26, Fig. 3) to the roller 9 instead of the chain 11 passing over the sprocket 12.
