Title: Improvements in or relating to travelling wave tubes
Inventor: HOGG HAROLD ALEXANDER CECIL
IPC: H01J23/083
Filed: 1958-04-24
Abstract: 911,893. Travelling wave-tubes. M-O VALVE CO. Ltd. April 20, 1959 [April 24, 1958], No. 13118/58. Class 39 (1). In a travelling wave-tube an annular electron beam is projected through the space between the helix 1, Fig. 1, and a central rod conductor 4 within the helix, the helix 1 being surrounded by a cylindrical electrode 2 and the potentials applied to electrodes 1, 2 and 4 being such that they function as an electrostatic focusing field which produces a " helical ripple " in the electron beam, the outer peak of the " helical ripple " being in the vicinity of gaps between the turns of the helix, and the lens D.C. potentials applied to 1, 2 and 4 are such that the helix 1 is positive (normally earthed) with respect to the cathode, the central rod 4 is negative (e.g. - 400v.) to the helix 1, and the cylinder 2 is negative to 4 (e.g. 2 can be at - 6900v.). The electron beam preferably passes between rod 4 and helix 1 but may alternatively pass between helix 1 and cylinder 2 in which case the D.C. potentials of 2 and 4 are interchanged. The helix is of Ni-Cr alloy wire and is carried by three ceramic rods 3 which rest against cylindrical electrode 2. The gun comprises indirectlyheated cathode 7, focusing electrode 9 made up of cone 13 anchored to plate 11 by three struts 14 and anode 10 made up of metal cup 17 secured to flanged disc 16 by three struts 18. The end turn of the helix 1 fits tightly around tube 15 so that the helix is at gun anode potential. The gun anode 10, focusing electrode 9 and disc 34 forming part of the cathode heater support fit in slots in three cylindrical ceramic blocks 32. The focusing electrode 9 is tied to the cathode, and three leads 35 are provided for cathode heater and gun anode. The rod electrode 4 is embedded at one end in cup 17 of gun anode 10 and at the other end in metal cap 26 forming a terminal, the terminal 30 of electrode 2 being taken through glass cylinder 25 and metal disc 23 serving as a support and D.C. terminal for collector 27. Lossy coating 44 on the central section of electrode 2 prevents oscillations. Input and output coaxial lines 36, 37 have their centre conductors 42, 43 connected to the helix 1 and their outer conductors connected to cylinders 40, 41 each of which is made in two parts. The gun anode 10 is earthed, the cathode at - 3000 volts and the collector 27 at +50 volts.

Title: Improvements in a galvanizing machine
IPC: B65G49/02
Filed: 1921-05-09
Abstract: 184,554. Rogers, F. H., (Meaker Galvanizing Co.). May 9, 1921. Endless-chain conveyers with articles hung on hooks; discharging and feeding devices; guiding. -A device for loading wheel rims or the like on to hooks on an endless band for convevance through a plating-bath comprises a rotating wheel A, Fig. 4, having pockets B into which the articles are fed down an inclined shoot 6. Two loading- wheels side by side, as shown in end elevation in Fig. 9, may be provided for loading pairs of hooks 50. The base 73 of each pocket is hinged at 75 to a hub-frame C and is provided with a lug 76 and a roller 78 which, as the pocket approaches its uppermost position, rides over a fixed cam 59, thus inclining the pocket into the position shown in dotted lines in Fig. 9. The pocket is restored to the vertical position on leaving the cam by a spring 79 secured to hub 62 so that the article 5 engages a hook 50 which has arrived in position in the meantime. The hubs 62 are keyed to a shaft 57 rotating in bearings 55, each of which is provided with a cam 56. While the pocket C is tilted, the cam 56 is engaged by a roller 72 at one end of a bell-crank lever 71 pivoted at 70. The other end of the bell-crank engages an adjustable screw at the end of a crank 81 on a shaft 80. The motion of the roller 72 is transmitted through the shaft 80, a crank 87, connecting-rod 88, crank 89, and shaft 90 to a wire flap 91, which is raised to press the articles 5 inwardly. The cam 59 is mounted loosely on the shaft 57, but is secured to the frame of the apparatus by a rod 60. There are preferably two independent chains 24, Fig. 4, side by side, each carrying pairs of hooks. After passing through the plating-bath the rims are discharged by similar mechanism into a hot-water tank having two oppositely rotating conveyers, one for each side of the apparatus. Each chain is driven through tooth and worm gearing from a pulley 15 and is guided by sprocket wheels 38, 39, 30. The loading and unloading wheels are driven by chains 37, 29 from wheels gearing respectively with the sprocket 50 and the main driving gear. As shown in Fig. 10, the hooks 50 are supported from yokes 48 having flanges 51 adapted to slide on cathode bars 43, supported by brackets 41 from cross bars 40. The anode bars 45 are hung from rods 44. The middle rods are insulated from the chains 24 by boards 46.

Abstract: 528,759. Rubber thread and strips. FIRESTONE TYRE & RUBBER CO., Ltd. May 4, 1939, No. 13362. Convention date, Aug. 1, 1938. [Class 70] In making rubber strip or thread, an unvulcanized rubber film is stretched, allowed partially to retract, heated to relieve the stresses and vulcanized. A strip of latex is formed on an endless band 13 by contact with a roller 12 dipping into a bath 10. The strip is dried as by carrying through a heated chamber 23 and is stripped from the belt by a pulley 24 driven at a speed about six times that of the belt. The strip passes round a pulley 28 driven slightly quicker than the pulley 24, a pulley 32 of the kind described in Specification 448,605, which causes the strip to be rolled to form a cylindrical thread and a pulley 34 driven at the same speed. The strip then passes on to a vulcanizing drum 36 which is driven at a speed less than that of the pulley 24, which allows relaxation of the thread to take place. The stresses remaining in the thread are removed by heating before vulcanization takes place. Heating before vulcanization may be effected by using in the latex composition a delayed action accelerator such as dipentamethylene thiuram disulphide or tetramethyl thiuram di- or tetra-sulphide.

Abstract: 716,791. Feeding sheets. LINOTYPE & MACHINERY, Ltd. Sept. 2, 1952 [June 6, 1951], No. 13416/51. Class 100 (1) Sheet-separators.-To ensure that only one sheet is separated at a time from a pile of sheets, a suction separator is used which lifts a sheet from the pile and rapidly vibrates the sheet. As shown, the suction foot is a hollow piston 1 which slides in an inner cylinder 3b which communicates through ports 10, 11 with an outer cylinder 3a joined to a source of suction through a pipe 6. A closure plate 7 has an extension 8 which forms a guide for the lower end of the piston 1, and a compression spring 13 is arranged between the plate and a head 12 on the piston to urge the latter inwardly of the cylinder 3b. When the space 2 in the cylinder 3b is evacuated, the piston 1 is drawn downwardly until it engages a sheet s. Since the head 12 has a slight clearance in the cylinder 3b, the sheet will seal the end of the piston, and the latter will rise with the sheet adhering thereto until a port 14 in the piston registers with a port 15 to atmosphere. At this stage, the sheet is stripped off the piston by a flange 9 on the extension 8. The sheet then drops from the piston, since the vacuum circuit is broken by ports 14, 15. The piston is again pulled downwardly as before, and the cycle of operations is repeated. The cycle operates at high speed and results in rapid vibrations of the sheet. Several such separators may be used, and the sheet may be further separated and forwarded to a printing-machine by any suitable gripping mechanism.
