Title: Improvements in or relating to electron discharge devices
IPC: H01J7/18
Filed: 1938-10-31
Abstract: 520,751. Obtaining high vacua. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 31, 1938, No. 31427. Convention date, Oct. 30, 1937. [Class 8(i)] [Also in Group XL] A method of liberating within the envelope of an electron discharge device an alkali or alkaline earth metal for gettering comprises heating a stable compound of the metal and vaporizing a reducing agent in the presence of the compound to reduce it and liberate the metal. The form of getter unit shown in Fig. 2 consists of a box of sheet nickel roughened on the inside and having its flanges spot welded together. The unit is mounted in the envelope of a device so that vapour escaping from the hole 7 is directed into the annular space round the pinch. The box is coated internally with a stable oxygen compound of the alkali or alkaline earth metal, such as caesium bichromate or permanganate mixed as a powder with nitrocellulose, diatol and diethyl oxalate. A coiled filament 8 of tantalum, tungsten, zirconium or molybdenum, is coated with the reducing agent or with a compound decomposable by heat, such as barium or bariumstrontium carbonate or barium beryllonate, and is connected at one end to the box and at the other end, passing through the hole 7, to one of the leads of the device. In using the device in making a photo-electric cell, after the cell is mechanically exhausted, the filament is heated to warm the box and evolve reducing vapour from the filament coating, which, if barium vapour, getters residual gases in the envelope. The amount of metal liberated is determined by controlling the heat of the filament. In an alternative construction a cylindrical housing 11, Fig. 3, enclosing a perforated metal ring 12 is pinched over one end of the filament 8 which makes a closed circuit with a supporting loop, so that it may be heated inductively. The ring, which may be of iron or other ferrous metal to assist in the reduction, is dipped in a solution of the alkali metal compound. An oxygen compound of an alkali or alkaline earth metal, such as caesium permanganate, may be produced on the nickel or iron plates may be reduced and caesium vapour liberated by heating the plate to 600‹C. and projecting on the coated surface barium or other alkaline earth vapour from a heated tantalum wire covered with a barium-strontium carbonate as described in Specification 494,150.

Title: Improvements in variable speed gears
IPC: F16H29/08
Filed: 1933-11-13
Abstract: 431,681. Variable-speed and reversing ratchet gearing. LOVELL, G., 74, Wormhalt Road, Shepherd's Bush, and WALKER, A. J., 53, Doughty Street, both in London. (Representatives of WALKER, P.) Nov. 13, 1933, No. 31624. [Class 80 (ii)] Variable-speed gearing comprises an input crank-shaft 9, Fig. 1, which oscillates a pair of levers 21, 21a, about a common pivot 22 which is adjustable to vary the speed on a vertical slide 20. The lower ends of the levers are connected to an output shaft 3 through connected pairs of intermeshing one-way devices such as 30, 31, Fig. 5, so that both levers are operative to effect a continuous drive. The crank-shaft 9 may be driven through a gear pair 7, 8, Fig. 2, from a driving-shaft 2 in line with the shaft 3. Links 12, 12a, Fig. 1, act upon pins 21b, Fig. 3, which slidingly engage the levers 21, 21a and which are supported by other links 13, 13a which rock freely about the axes of fulcrum wheels 14, 14a. Each fulcrum wheel carries a pin 37 which slidingly engages the adjacent transmission lever 21, 21a. These levers rock on telescoping bosses 22, 23 in a hole 24 in a fulcrum block 18 which is moved by a manual screw 16 to vary the amplitude of the oscillations imparted to the fulcrum wheels 14, 14a. The wheel 14 meshes with separate wheels 26, 26a, Fig. 2, which are loose on pivot shafts 28, 29, Fig. 1, and which have bosses 36, Fig. 5, which project into oppositely-acting one-way clutches 36b inside the bosses 30, 31 of intermeshing pinions 34, 34a, Fig. 2. Since the bosses oscillate together in the same direction, the gear pair 34, 34a is driven in one direction on both swings of the bosses 36, and therefore on both forward and backward swings of the lever 21. Another pair of intermeshing pinions 35, 35a is driven on both swings of the lever 21a through the fulcrum wheel 14a, separate wheels 27, 27a, and one-way bosses 30a, 31a. These pairs of pinions have a rigid cross connection, 82, Fig. 6. It therefore follows that a pinion 32, Fig. 2, splined on the shaft 3 and meshing with the long pinion 35 receives four rotary impulses for each turn of the crank-shaft 9. The drive of the shaft 3 is reversed by sliding the pinion 32 so as to mesh only with the other long pinion 34. In a modification in which the transmission levers act successively in one direction only of their swing, the fulcrum wheels are omitted. The lower ends of the two levers are connected by simple links to levers 63, 64, Fig. 10, which oscillate on a pivot shaft 65. The driving impulse of the lever 63 is transmitted directly through a one-way clutch, not shown, to a boss 66 which is rigid with a transmission pinion 66a adapted to be engaged by a change pinion corresponding to the pinion 32 of Fig. 2. The driving impulse of the other lever 64 is imparted to the same transmission pinion 66a through a gear pair 67, 68, then through a one-way clutch, not shown, to a boss 70<1>, then on through a gear pair 70, 66b and the boss 66. Reversal of drive is effected by sliding the change pinion from the pinion 66a to the long pinion 70.

Abstract: 485,585. Direct - call party line systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 20, 1936, No. 31861. Convention date, Dec. 17, 1935. [Class 40 (iv)] In a direct-call party-line system, the substations employ local sources of current for sending selecting impulses which are not powerful enough themselves to operate the selectors and are relayed by apparatus common to all the subscribers. In one embodiment, described without reference to drawings, the signals from the substations are in the form of 500-cycle current which controls a tuned relay at the central point. As shown, the hook-switch TK completes a circuit from the microphone battery through an extra winding 15 on the selector stepping magnet, and interruptions of this circuit by the dial D induce impulses in the line winding 14. Rectifiers L1 at this and the other stations ensure that the impulses shall not affect the selectors. Relay SR1 at the central point responds to the impulses and controls a relay SR2 which repeats them into the line from an A.C. source or a D.C. source of suitable polarity. All the stepping magnets respond and the selector at the wanted station connects up a bell. A sluggish relay R1 disconnects the receiver while the selector is being stepped. Some or all of the stations may have separate transformers and single-wound stepping magnets.

Abstract: 945,443. Stretching thermoplastic films. ASAHI KASEI KOGYO KABUSHIKI KAISHA. Sept. 5, 1961 [Sept. 5, 1960; July 8, 1961], No. 31917/61. Heading B5B. Flat thermoplastic films are simultaneously stretched longitudinally and transversely by engaging opposite edges of the film, while under tension between feed and pull rolls, with a pair of series of clamps carried by the moving film along guides. The extent of stretching is determined by the difference in speed between feed and pull rolls and the configuration of the guides. The film may be heated before, during or after stretching by, e.g. steam, hot water, hot air or radiation. The films may be of e.g. crystalline polypropylene, polyesters, polycarbonates, polyethylene, polyvinyl chloride, polystyrene, polyamides, copolymers of vinylidene chloride and vinyl chloride, polyurethanes or polyurea. In a preferred embodiment the transverse stretching means comprises endless guides 46 and 47 (Figs. 2 and 5), in which a plurality of clamps 10-16, 30 and 31 freely run independently of each other on wheels 53 and balls 64. Sprocket wheels 35 and 39 feed the clamps to and from the film while sprocket wheel 43 moves them along the guides. The clamps and film are engaged and disengaged by having the guides of higher and lower cross-section at appropriate places, thereby forcing jaws 50 and 51 together to clasp the film 4 or allowing the jaws to part by means of spring 60, thus releasing the film. In the vicinity of the sprocket wheels, the guides have an open wall to allow the sprockets to engage arms 56 and 61 on the clamps. In operation, unstretched film from bobbin 1 to feed rolls 6 and stretched longitudinally by tension from pull rolls 7. Meanwhile the film is engaged by clamps 10 and 11, which are then moved by the film to 12 and 13 and thence to 14 and 15, thus transversely stretching the film. At the end of the guides, the increased hight thereof disengages the clamps, which are turned by sprockets 38 and 39 to be returned via sprockets 42, 43, 34 and 35 to the film. The stretching apparatus may be used in conjunction with the film extrusion means, without any intermediate wind-up of the film. In an example, polycaproamide was melt-extruded through a T-die at 235 C., chilled at ambient temperature, and the resulting 0.22 mm. thick film was simultaneously stretched to a ratio of 3.0 longitudinally and transversely.
