Abstract: 588,885. Filters. GLENFIELD & KEN-. NEDY, Ltd., and BOUCHER, P. L. March 9, 1945, No. 5889. [Class 46] [Also in Group IX] A filter for water comprises a movable screen of corrosion-resisting wire fabric woven plain or twill, with straight warps and crimped wefts and presenting apertures of microscopic proportions, the filter being cleaned by nozzles directing cleansing jets of water or air against changing surfaces of the screen. The apertures may be reduced by flattening the wires after weaving, or the wires may be initially of elongated cross-section. As shown, the screen forms the peripheral wall of a rotary drum 1 driven by an electric motor 3. The drum is mounted in a chamber 2 with an inlet 12 for water which enters the drum through one side, and passes out through the screen. Above the drum is a row of nozzles 5 each comprising a short tube closed at both ends and formed with a narrow slot. The nozzles are displaced alternately on opposite sides of the vertical plane containing the axis of the drum. Water jets from the nozzles clean the screen, the debris falling into a hopper 9 provided with an outlet pipe 10. Adjustable splash plates may be pivoted at the sides of the row of nozzles. Instead of a rotary drum a rotary disc or an endless band may be used. Specification 429,422 is referred to.

Title: Improvements in the manufacture and production of butadiene
IPC: C07C1/24
Filed: 1929-02-22
Abstract: 329,396. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 22, 1929. Diolefines are obtained by treating 1 :3-butylene glycols together with water vapour with a catalyst comprising an oxide of a metal or non-metal having a dehydrating action or a borate of such oxides. Instead of oxides compounds such as hydroxides, carbonates, nitrates, or oxalates, which furnish an oxide under working conditions may be used. Suitable oxides are alumina, silica, and thoria. Activating additions may be made to the catalyst such as copper sulphate or red phosphorus. In an example butadiene is obtained by passing butylene glycol over a catalyst prepared by soaking pumice with thorium nitrate and heating. The yield may be increased by an addition of water vapour. Specification 317,500 is referred to.

Abstract: 471,200. Treating sewage; cooling liquids. SCHREIBER, A. March 2, 1936, No. 6308. Convention date, March 1, 1935. [Class 111] [Also in Group XII] Sewage or foul water is passed in contact with air as a long, continuous, sinuous, shallow; stream flowing successively over each of a vertical pile of trays. The liquid is delivered at 22 to the top tray of the pile shown in Fig. 6, and is caused by ribs 20 to take the course indicated by the arrows. It passes through an outlet 23 to the tray next below and so throughout the pile. Air is freely admitted at the sides of the pile. As shown the trays are arranged with the ribs on successive trays at right-angles, and each tray is slightly inclined at right angles to the ribs thereon. Fig. 1 shows an arrangement comprising two piles 1, 2. The liquid from the top tray of pile 1 passes by a channelled bridge 7 to the top tray of pile 2, from which it is passed back by a bridge 71 to the second tray of pile 1 and so on through the piles. With a similar arrangement there may be a two-course flow, liquid being delivered to the top tray of each pile, flowing thence to the second tray of the other pile and then back to the third tray of the pile to which it was delivered, and so on. With two piles the trays of either pile are inclined in the same direction but in the opposite direction to those of the other pile. The trays may be supported directly on top of one another or there may be intermediate rectangular or wedge-shaped spacing pieces. The trays may be made of asbestos cement. The Specification as open to inspection under Sect. 91 states that the apparatus may be used for other purposes, for example, cooling. This subject-matter does not appear in the Specification as accepted.

Title: Floating airbase
IPC: B63B35/53
Filed: 1972-02-11
Abstract: 1428951 Floating airbases C J DONOVAN 3 April 1973 [11 Feb 1972] 6403/72 Heading B7A A floating airbase is supported on upright hollow pillars whose lower ends are open so that seawater traps air in the pillars to provide part of the necessary buoyancy. The remaining buoyancy is provided by an underwater buoyancy chamber which is welded to the pillars and which in plan projects outwardly beyond the airbase superstructure. The pillars are cross-braced by steel tie rods on a geodetic principle and protrude about one hundred feet above the water surface to support the airbase clear of wave crests. Compression or expansion of air inside the pillars caused by airbase movement provides a righting moment. A central pillar is larger than the remaining pillars so that it acts as a pendulum to give a righting action. The height of the airbase can be changed by pumping air into, or releasing it from, the support pillars. The airbase may have a single runway, a pair of runways arranged as an X or V, or three runways in the form of an equilateral triangle. In the latter case the airbase buildings may be at the centre of the triangle. Alternatively, the airbase may be circular or may be square with the airbase buildings at its corners. The airbase is maintained in position by sea anchors, and, if water depth permits, drag anchors. Preferred dimensions are disclosed.

Abstract: 706,199. Electric beam apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 28, 1952 [March 28, 1951], No. 7152/51. Class 39(1) A circuit embodying an electronic storage tube having a secondary-electron emitting electrode and a charge storage electrode is arranged so that in order to perform a writing operation, the storage electrode is charged by secondary electrons derived from the secondary emitting electrode, and to perform a reading operation, secondary electrons are employed which are also derived from the secondary emitting electrode. The tube may comprise a secondary emitting electrode 2, a storage electrode 4 in the form of a mesh with insulating elements 5, a signal electrode 6 and an electron gun 7. The electrode 2 may be at zero potential, the electrode 4 at one or two volts positive, the signal electrode 6 at 5 or 6 volts positive, and the electron beam may be arranged to scan the electrode 2 with an energy of 500-2000 volts. Signals to be stored are applied negatively to the electrode 2 so that corresponding negative charges are applied to the insulating elements 5 by means of the secondary emission from the electrode 2 caused by the scanning beam. In reading, the electrode 2 is at a constant potential and the number of secondary electrons emitted from it which can pass through the electrode 4 to the signal electrode 6 is controlled by the charges on the insulating elements 5. To remove the stored charges, the electrode 2 is held about 100 volts negative and flooded with high-velocity electrons.

Abstract: 866,088. Wrapping- machines. DOUGLAS & CO. Ltd., CHARLES E., and MARDEN, B. E. March 5, 1959 [March 6, 1958], No. 7275/58. Class 94(1). In a wrapping machine of the kind described in Specification 692,858, the article support 4 beneath the die aperture 3 is moveable to one side so that the article is swept off the support on to a discharge shoot 25. The support 4 is allowed only limited downward movement against springs 9 when an article to be wrapped is pressed through the die, and is held depressed by a latch 38 engaging a collar 7 on its shaft 5. After wrapping is complete, a pedal 36 is pressed which, through linkage 31-35, causes pivoting of an arm 26 on a shaft 27, the arm 26 carrying the tube 6 in which the support shaft 5 is held. The support 4 is thus swung to one side and a projection (not shown) pushes the wrapped article onto the shoot 25. Linkage 28-30 connecting the shaft 27 to the pivot bearing of the annular carrier 14, raises the latter at the same time as the support is moved, to enable a new wrapper to be laid over the aperture. The shoot 25 is arranged to tilt under the weight of the article to cause it to slide clear of the machine. Return movement of the support 4 results in withdrawal of the latch 38 through means 39-41.

[Also in Group XXIX] Each cylinder 10, Fig. 2, of a fluid compressor has an annular-plate inlet-valve 16 seated by springs 18 and a spring-closed outlet valve 20, the inlet valve having pins 32 associated therewith, which pins are supported in a ring 30 slidable over the cylinder 10. When the compressor is started and the pressure in its lubricating system has risen to a sufficient value to overcome the spring loading of a servomotor 44, the latter moves a frame 38, Fig 1, so that stops 36 thereon tilt rockers 28 located on opposite sides of each cylinder and allow springs 34 around each pin 32 to lower the ring 30 and pins 32 to permit the inlet valves to be seated by springs 18 and enable the compressor to start pumping. In the inoperative condition of the compressor the servomotor spring urges the rockers 28 to the upright position and opens the inlet valves to provide decompression during starting. Each rocker 28 is connected to the frame 38 by a spring 46 so that upon raising the rockers each cylinder will be decompressed instantly or upon completion of the compression stroke therein. If a frame is provided for each cylinder the springs 46 may be dispensed with and the rockers are raised by stops 48 on the frame coming into contact therewith. To ensure that the electric motor or other means driving the compressor reaches full speed before the servomotor is actuated, the oil pipe leading to the latter may contain an expansion member or throttle. Either the springs 46 or stops 48 may be used to raise the rockers, and in Fig. 1, the stops 48 are provided to facilitate assembly of the mechanism.
