Title: Process for forming honeycomb or like grids for electric discharge devices
IPC: H01J19/00
Filed: 1943-11-03
Abstract: 575,320. Electric discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT, W. J. Nov. 3, 1943, No. 18184. [Class 39 (i)] [Also in Group XXII] A metal grid of honeycomb or like form is made by assembling wires or strips of deformable metal coated or interleaved with the metal of which the grid is to be made, compacting to reduce the cross-section of the assemblage, and removing the wires by a chemical which will not attack the grid metal. A section is preferably cut from the assemblage having the required thickness to form a grid, before removing the wires, but this may be done after; The assemblage may be placed before compacting in a metal tube of or lined with the grid metal. Iron wires electro-plated with platinum, silver or gold may be placed in an iron tube, electroplated inside with the same noble metal, or copper-plated with silver or gold, may be used. In another modification the compacted wires may be electro-plated to form an outer tube. The iron could be removed by hydrochloric or nitric acid. In another modification the wires are coated with tungsten or molybdenum oxide which is then reduced to metal by hydrogen. The compact mass or the discs cut therefrom may be sintered in hydrogen. A grid for high temperatures is made by winding tungsten wire, 0.001" in diameter, on molybdenum wires 0.04" in diameter. Nineteen of these are placed in a tube of tungsten 0.005" thick, spaces being filled by a sludge of fine tungsten powder 'in water. The bundle is pushed into a tube and the end plugged with a rod, both of molybdenum. The whole is swaged till the diameter is 2 to 2¢ mm. and discs 0.01 to 0.05" are cut off by a thin grinding wheel. These are heated for over 15 minutes to over 1850‹ C. in wet hydrogen, the flat faces are ground and the molybdenum dissolved out with a mixture of nitric and sulphuric acids and water. In a modification, the molybdenum wires are coated with tungsten by heating them in tungsten oxy- or hexa-chloride vapour. The method enables fine grids to be made, for use in valves for still shorter wavelengths, and also successive grids with all their holes in alignment to give maximum transmission of an axial electron beam.

Title: Improvements relating to change-speed gearing
IPC: F16H61/02
Filed: 1950-07-20
Abstract: 676,055. Change-speed gearing; clutches. DAIMLER-BENZ AKT.-GES. July 20, 1950 [July 22, 1949], No. 18207/50. Class 80 (ii). Planetary change-speed gearing for motor vehicles comprises a planet carrier 2, 5 rigid with the driving shaft 1, an annulus 6 rigid with the driven shaft 8, and a sun wheel 7, 9 which is adapted to be arrested by a brake 10 to give overdrive but which is normally coupled to a polygonal sleeve 17 fast on the shaft 1 by doubleacting wedging rollers 18 so as to give bi-directional direct drive, the rollers being rendered inoperative in the forward direction (clockwise in Figs. 3, 5, 6) prior to and during overdrive while remaining operative in the reverse direc-. tion so that the gear jams in overdrive when the vehicle tends to move rearwardly and thus prevents such movement. The cage 21 for the rollers 18 has an arcuate recess 22 into which a ball 23 is adapted to be moved by a conical part of a spring-loaded piston valve 24 which is movable by pressure fluid admitted through a passage 26 to the space 27 behind the valve and which controls the passage of the pressure fluid through a passage 14 to a piston 13 applying the brake 10. So long as the brake 10 is disengaged, the valve 24 then occupying the position shown in Fig. 1, the rollers 18 act to couple the sun 7 to the carrier 2, so as to produce direct drive, whether the engine drives or the vehicle over-runs, the ball 23 being moved out of the recess 22 during such over-run, as shown in Fig. 5. To change to overdrive, pressure fluid is supplied to passage 26, tending to move valve 24 to the right. Such movement is, however, prevented by the ball 23 if the vehicle is over-running, and the change can accordingly take place only when the engine is speeded up to driving condition, whereupon the ball reengages the recess 22 and the valve 24 is free to move to the right, causing the brake 10 to be engaged to produce overdrive, whether the engine drives or the vehicle over-runs. The rollers 18 now occupy the position shown in Fig. 6, backward movement of the cage 21 being limited by engagement of the forward end of its recess 22 with the ball 23, which is now held in the recess by a cylindrical part of the valve 24. The valve 24 is held in its new position by the pin, 34 of a spring-loaded piston 33 in the sleeve 17 engaging a radial surface 36 of the valve. To release the valve, so as to allow it to return to direct gear position after supply to the passage 26 has been cut off, pressure fluid must be supplied to passages 31, 30 so as, firstly, to retract the piston 33 with its pin and, secondly, to engage a friction clutch 11 which is arranged between the sun 7 and the carrier 2 and which serves to synchronise the parts so as to prevent shock, particularly when the vehicle is overrunning. The supply of pressure fluid to passage 26 may be controlled manually or automatically by speed, while the. supply to passages 30, 31 can occur only when supply to passage 26 has been cut off. A main change-speed gear is arranged in front of or behind the planetary gear.

Title: Improvements relating to the manufacture of flat glass
Inventor: PLUMAT EMILE
IPC: C03B18/14
Filed: 1966-04-27
Abstract: 1,145,142. Treating surfaces of glass sheets. GLAVERBEL. 27 April, 1966 [6 May. 1965]. No. 18530/66. Heading C1M. In a process for modifying a property or properties of flat glass or a layer of molten or plastic glass being formed by the float process, the glass is passed over and in contact with a bath of molten material denser than the glass and is traversed by an electric field extending between the molten material and the atmosphere in contact with the upper surface of the glass. In a particular embodiment, a glass ribbon 10 passes through a tank and floats on the surface of a bath 12 of molten tin or tin alloy contained therein. A single plate electrode 14 is supported in the atmosphere above the sheet and three smaller rod electrodes 16 are placed in the molten metal bath below the upper electrode. The electrodes are connected to a D.C. supply 17 of up to 80 volts, a switch being incorporated to connect either electrode to the negative terminal. Tubes 20 protrude through the tank sidewalls into the atmosphere above the sheet but below the plate electrode 14. Through these tubes can be fed an ionized substance. By correct setting of the polarity of the electric field the ions discharged into the atmosphere are caused to be exchanged with ions in the glass surface and simultaneously ions can be caused to migrate from one surface to the other of the sheet and from the sheet to the molten metal bath. Thus, the sheet can be chemically tempered, be coloured, or have its optical properties modified. The upper electrode may be angled or curved with respect to the lower electrodes so that the strength of the electric field can be varied across the width of the glass sheet, thereby creating zones wherein the surface properties are differently modified. Further the upper plate electrode can be constructed with large perforations also to modify the surface properties in zones. In an alternative embodiment the upper electrode may be replaced by three separate electrodes, two above and close to the edge of the sheet and a central one more distant from the glass sheet. In its application to the float process the glass composition may be modified, whereby the surface tension of the glass layer with respect to the molten metal bath is altered, thus producing a glass having a different equilibrium thickness.

Title: Apparatus and method for the recovery of lead from lead/acid  batteries
IPC: H01M10/54
Filed: 1972-04-21
Abstract: 1412295 Circular saws L WORONOWSKI 20 July 1973 [21 April 1972] 18586/72 Heading B5L [Also in Divisions B2 and H1] Spent lead-acid batteries 12 are transported on their sides on a conveyer 11 from a loading station 13 to a locating unit 100, described with reference to Figs. 7-9 (not shown), where they are accurately positioned and clamped against the conveyer such that the normally top side 17 of the battery carrying the terminals overhangs one side of the conveyer where a saw unit 16 is located. The saw unit includes a circular saw 22 (Figs. 10a, 10b, not shown) operating about a horizontal axis, the plane of the saw being parallel to the direction of movement of the conveyer whereby the top side 17 is cut off from the remainder of the battery casing 18 enclosing the lead plates. The top portions 17 carrying the terminals fall on to a conveyer 19 and are transported to a separating station 20, described with reference to Figs. 2, 3 (not shown), where they are crushed and the heavier lead particles are separated from the lighter particles of other material by an air stream which supports the lighter particles. The casing 18 with the lead plates continues on the conveyer 11 to a discharge station 14 where it is removed by a deflector plate 40 on to a platform 41 of a unit 42 serving to remove the plates from the easing. The unit 42, Fig. 4, receives the casing 18 so that its open side is towards the left as shown in the Figure and the casing is held on the platform 41 by a clamp 47. The platform 41 is carried between a pair of arms 49 pivoted about a horizontal axis at their lower ends and the arms are swung counterclockwise to be arrested by a stop 51. The shock induced by impact with the stop 51 causes the lead plates 54 to drop out of the casing 18 on to a conveyer 53 for transport to a collection point. The clamp 47 is released and a ram 55 transfers the casing 18 from the platform 41 to a conveyer 60 for transport to a collection point. During transport on the conveyer 60 the casing is washed by water jets (Fig. 11, not shown) situated beneath the conveyer. Before arrival at the loading station 13, the batteries may be placed in an inverted position on a conveyer for drainage of acid (Fig. 12, not shown).

Abstract: 811,466. Hydraulic brakes. AUTOMOTIVE PRODUCTS CO. Ltd. June 17, 1957 [June 15, 1956], No. 18646/56. Class 103 (1). [Also in Group XXIX] A liquid pressure braking system includes a plurality of brake-operating motor cylinders 27, 28 and a control valve 24 arranged to supply liquid under pressure to each motor cylinder from a different one of a plurality of liquid pressure accumulators 17 and 18, and a pump 10 arranged to supply liquid under pressure to the accumulators 17 and 18 through a cut-out valve 14, the control valve 24 also controlling a normally open return flow path for liquid from the cut-out valve 14 to the liquid reservoir 11, one of the motor cylinders 27 being so connected to the flow path that pressure built up by closing the flow path at the control valve, operates the cylinder 27. As shown in Fig. 2, the control valve 24 comprises a plunger 73 operated by the pedal 32, the thrust through plunger 73 being transmitted by spring 76 to a cup-shaped member 72, which acts upon the spherically shaped top end of a further plunger 43. Downward movement of plunger 43 has the effect of interrupting flow of liquid from the cut-off valve 14 entering the valve at port 52 and passing away to the reservoir 11 through conrection 49. Simultaneously pressure liquid from reservoir 17 entering at connection 51 is enabled to pass valve surface 45a to port 52 which, as well as being connected to the cut-off valve 14, is in communication with the brake cylinder 27. In a similar manner a second plunger 44 below plunger 43 is also moved down and acts to cut off communication between port 58 connected to the brake cylinder 28 and the line 31 to the reservoir 11. Valve 46a is opened to allow pressure fluid from port 57 and reservoir 18 to pass to the brake cylinder 28. Passages 59, 61 and 60, 62 in the plungers 43 and 44 respectively enable the liquid pressure existing at the ports 52 and 58 to be transmitted past flow-restrictor plugs 65 to act in the spaces below the plungers and cause them to be substantially balanced.
