Title: Improvements in or relating to Pulling-over Machines.
IPC: A43D13/00
Filed: 1917-08-22
Abstract: 119,262. British United Shoe Machinery Co., [United Shoe Machinery Co.]. Aug. 22, 1917. Pulling-over.-Machines of the type described in Specifications .12304/03, 3301/10, 3876/14, and 16398/15 are provided with vamp-pressing means which stretch the upper laterally towards the marginal 'edges engaged by the side grippers. The invention is described as applied to the machine described in Specification 12304/03, the rubber-covered side clamp blocks 8 of which, however, though free to adjust themselves angularly to the work, have no yielding movement outwardly on their supporting-arms 6. Each vamp-presser 20 is connected at its inner end by a universal joint to a carrier 15 pivoted to a spring-pressed horizontal slide 10, which is mounted in a block 12 rigidly secured to the arm 6, while the outer end of each presser rests on a spring plunger 22. The carrier 15 is supported by a lever 16, which is pivoted at 17 to the block 12 and is normally held by a spring 18 with its inner end upraised to an extent limited by an adjustable stop 19. Fig. 1 shows the normal positions of the vamp pressers 20, which do not obstruct the view of the upper. In the operation of the machine, as the arms 6 are moved inwards the carriers 15 engage each other and then yield outwardly in the blocks 12, riding over the levers 16 which force the carriers upwards to separate the pressers and cause them to engage the shoe while occupying the angular positions shown in Fig. 1. Continued movement causes the plungers 22 to yield so that the pressers tip outwardly and rub the upper towards opposite sides of the last After the pressers reach the position shown in Fig. 2, the levers 16 yield against the action of their springs 18, and the arms 6 complete their stroke for bring- ing the clamp blocks 8 into engagement with the shoe.

Title: Improvements in and relating to preparation of tungsten and molybdenum carbonyls
IPC: C01G41/00
Filed: 1951-05-23
Abstract: Tungsten or molybdenum carbonyl is prepared by reacting an oxychloride of tungsten or molybdenum, or an inferior grade of the chloride of tungsten or molybdenum containing substantial amounts of oxychloride, with carbon monoxide in the presence of not more than 2 per cent of a carbonyl of iron, nickel, or cobalt; alternatively an iron group metal may be present at the start of the reaction, so that the carbonyl is formed as reaction proceeds. The reaction may be carried out in a pressure vessel at 1.500lbs./sq. inch and 100 DEG C in the precence of powdered aluminium or aluminium alloy, e.g. containing copper, aluminium, and zinc, and of ether.  In an example the reaction is effected in the presence of anhydrous iron chloride instead of iron or iron carbonyl, which shows that iron in a form unsuitable for making carbonyl during the reaction is not effective in the process.

Title: Improvements relating to combined couplings and buffers for railway vehicles
IPC: B61G1/08
Filed: 1920-05-01
Abstract: 162,539. Bachmann, A. May 1, 1920. Buffers; combined buffer and draw-gear; couplings, automatic, convertible to non-automatic.- Relates to automatic couplings of the kind in which the pivoted hook 11, Fig. 1, of each vehicle is adapted to engage the hook spindle 10<1> of the opposite vehicle and the coupler-heads are mounted with compensating buffer-heads 1, 2 on a draw-bar 4 having draw and buffing springs 7, 8 respectively. According to the invention, the hook spindle 10 and a transverse uncoupling- shaft 12 are mounted in connection with the buffer-heads, and are engaged by a lever 30, which is adapted to slide longitudinally in a cradle 26, Figs. 2 and 4, having rollers 27 and is provided with a weight 29 whereby the couplerheads are counterbalanced. The hook 11 is provided with two tail arms 16, 17, of which the former embraces the shaft 12, and the latter is provided with a recess 18 and is engageable by the cam 14 carried by the uncoupling-shaft 12. An angle-piece 19 is also loosely mounted on the spindle 10 and connected with the tail arms 16, 17 by a pin 20, from which is hung a second weighted lever 21 connected by a loose link 31, Fig. 2, with the lever 30. The angle-pieces 19 are adapted to engage the under surface of the opposite coupling-hooks so that actuation of one shaft 12 releases both couplings. The levers 21 have forwardly extending arms 23 which come into engagement when the vehicles approach and simultaneously ensure the hooks falling to their coupled position and also permit the weight 22 on the lever 21 to be utilized for keeping the hooks in this position. The uncoupling-shaft 12 is connected to an operating-shaft 32 having a weighted handle 33, which normally tends to hold the cam 14 in the vertical position as shown in Fig. 4, but which can be held in a raised position by a pin 35 so that the cam 14 engages the recess 18 and holds the hooks 11 in the uncoupled position, for example, for shunting purposes. The action of the coupling is as follows. Normally the hooks are in the horizontal or setfor-coupling position, with the cam 14 vertical, and the lever 21 co-operating with the lever 30 to counterbalance the coupler-heads. When the vehicles approach, the hooks 11 ride over and drop into engagement with the spindles 10 and are held thus by their own weight and the weight 22. Uncoupling is effected by rotating the shafts 32, 12 and cam 14, and the hooks may be held in the raised position by use of the pin 35. The interengaging buffer-heads 1, 2 are of pyramidal shape, and the headstock 9, Fig. 4, is provided with a cup 37 engaged by a spherical part 38 so as to permit flexing of the couplings. An ordinary draw-hook with safety coupling on one vehicle may engage with the hook spindle 10 of a coupling as above described.

Title: Improved method of manufacturing filamentary cathodes
IPC: H01J9/06
Filed: 1944-06-27
Abstract: 585,604. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 27, 1944, No. 12217. Convention date, Feb. 24, 1943. [Class 39 (i)] [Also in Group XXII] Tabbed filamentary cathodes for thermionic valves are made by laying the filament wire between two superposed strips of metal provided with registering windows over which the wire is placed midway between the sides thereof and held by the ends or webs of the windows, welding the wire to the ends or webs of the windows and removing the unwelded parts of the strips. Two nickel ribbons 1, 2 provided with a succession of windows 3 are fed by rolls 33 from reels 10, 11 over an idle roll 13, then over a sprocket-wheel 14 with teeth shaped to mesh with the windows, and then over separating rolls 16, 17 through guides 23, 25. The wire 4 of tungsten or tungsten-molybdenum is fed from a reel 12 over rolls 18, 19 and between the ribbons 1, 2 through a guide 24 provided with a V-shaped groove so as to place it midway between the sides of the ribbons. After emerging from the guides the assembly passes between electric-welding rolls 26, 27. The welding switch 29 may be closed by a trigger 28 moved up or down as the windows pass thereunder. The assembly may be wound on reels for storage or may be fed step by step through masking plates 31 between which electron emissive material 6 such as barium or strontium carbonate is sprayed on the filament. The assembly then passes through cut-off dies 35 carrying a spring-biassed blanking tool for cutting the ribbon parallel to the weld to remove the parts 8, Fig. 10, and a cut-off knife for severing the ribbon midway between the ends of the windows. The weld 5, Fig. 11, terminates at a point removed from the edges of the two nickel pieces, the unwelded edge portions of which flare slightly and thus provide a funnel or ferrule slightly tapered away from the wire, so as to support the wire near to the welding point, and thus to avoid bending forces at the region of the weld likely to break the wire.

Title: Improvements in electric clocks
IPC: G04C1/06
Filed: 1936-04-29
Abstract: 474,389. Electric clocks. POLLAK, J. E. (Borg Corporation, G. W.) April 29, 1936, No. 12231. [Class 139] In clocks wherein the driving means is periodically re-energized automatically by an electromagnet due to partial deenergization thereof, means, for example, a bimetallic strip, is provided in the electric circuit for disconnecting the current supply should the electromagnet be energized for an abnormally long time, and for automatically restoring the supply after a predetermined time interval. A maintaining spring drives the clock during re-energization of the driving means. The timing mechanism A, Fig. 1, comprises a ratchet wheel 15, Fig. 6, driving through a maintaining spring 16, a hub 12 rigid with a wheel 13, geared to the escapement and frictionally driving the minute shaft 10. The ratchet wheel 15 is advanced by pawls 24 on a pivotal armature 17 urged to rotate by the mainspring 28 connected thereto at 29 and anchored at 30. When the mainspring is run down a pin 53 on the armature rocks a pivotal contact lever 37 through its arm 51 beyond the dead centre to close the circuit of the electromagnet 36 at contacts 40, 41. The armature 17 is attracted to the position shown in Fig. 2 to stress the spring 28 and the circuit to the magnet is opened by the pin 53 rocking the contact arm 37 in the reverse direction through its arm 52. During this winding operation, the ratchet wheel 15 is held by a detent pawl 27 and the maintaining spring 16 drives the timepiece. The snap action of the contact arm 37 is effected by a link 45 pivoted between the contact arm 37 and a spring arm 47 fixed at 48. Should the battery supplying current to the magnet be run down, the magnetic attraction may be insufficient to rock the armature 17 far enough to open the circuit at contacts 40, 41. To prevent damage to the magnet coil in such a case a bimetallic strip 54, Fig. 5, is included in the circuit thereof, to break the circuit after a predetermined time, the circuit being then made and broken intermittently, definite make-and-break being ensured by the Vend of a spring 59 past which the free end of the bimetallic strip 54 has to spring past.

Title: Visible filter clogging indicator
IPC: B01D35/143
Filed: 1961-04-05
Abstract: 924,189. Filter clogging indicators. BENDIX CORPORATION. April 5, 1961 [April 11, 1960], No. 12232/61. Class 46. When a pin 62 is released, by movement of it to the right, from diametrically-opposite notches 42 in the end of an axially- and rotationally-fixed cage 38, a shaft 56, in a groove 58 of which pin 62 also engages, is free to rotate. When the shaft 56 is thus free, an indicator button 48 can be pushed out by a spring 54, the indicator button during its movement causing the shaft to rotate by engagement of helical slots 50 in the walls of the button with a pin 60 extending through the shaft. Pin 62 has been permitted to move to the right by movement to the right of a piston 66 (to the left of which filter inlet pressure is applied, and on the right of which, within a bladder 70, filter outlet pressure is applied) upon attainment of a predetermined pressure differential, e.g. on clogging. When this pressure differential is due only to a low-temperature viscosity rise, the solidification by freezing of a " fluid located between piston 66 and bladder 70 prevents movement to the right of piston 66, and thus prevents movement outwards of the indicator button. A spring-loaded fluted by-pass valve (not shown) is provided between the inlet and the outlet of the filter. Specification 879,324 is referred to.

Abstract: 981,106. Pneumatic tyres. TEXTILE & CHEMICAL RESEARCH CO. Ltd. March 29, 1963 [March 29, 1962], No. 12686/63. Heading B7C. In making a pneumatic tyre comprising rubber composition reinforced by cabled yarns of heat-shrinkable synthetic fibres, the rubber composition has a sufficiently high vulcanization rate for it to set hard before the yarns have been substantially shrunk at vulcanization temperature. The process is suitable for bicycle tyres. The fibre may be polyhexamethylene adipamide (nylon 66), and yarns may be overstretched and set at elevated temperatures, possibly before or during application of adhesive, and then formed into sheets with the rubber composition. The sheets may be stentered prior to calendering. The composition should have a vulcanization rate below 3 minutes at 140‹ C. as measured on a Wallace vulcanometer. In an example given, cabled yarns are overstretched by 8%, formed into sheets with a rubber composition, and the sheets moulded and vulcanized at 185‹ C. for 3 minutes to form tyres.
