Abstract: 452,045. Thermionic electrodes. BULL, C. S., 33, Micawber Avenue, Hillingdon, Middlesex. Feb. 16, 1935, No. 5094. [Class 39 (i)] Anodes are formed of two materials, the one subject to electron bombardment being of low thermal conductivity for example iron or nickel, the second of high thermal conductivity-for example copperbeing arranged in contact with the non-bombarded surface of the first to conduct heat away by means of a fin or fins. A T-shaped copper piece 1 has its head enclosed in an iron plate 6 forming the anode surface ; the leg of the T may be enclosed by a bent iron plate 5 extended to take under the bent over ends of the head. In a boxform anode the copper part is of H-section. As the outer part of the anode is of iron degassing by high frequency field is readily effected. When the bombarded surface is of nickel, iron parts are provided to make the degassing easy. In the Provisional Specification it is stated that the position of the iron and copper parts may be interchanged.

Title: Photographic process for producing a line image
IPC: G03C5/02
Filed: 1948-02-20
Abstract: 669,633. Photographic outline images. BULLOCK, P. W. Feb. 20, 1948, No. 5116/48. Drawings to Specification. Class 98 (ii). A line image of an object is made by providing the object with a background, illuminating either the object or the background so as to create a strong even light contrast between them, exposing a photographic material thereto, giving this a first development until a strong even density contrast is obtained between the images of the object and background elements, removing the material from the developer and exposing it to a weak light, giving the material a second development until the opposing densities match whereby density contrast between the two elements is destroyed but an even clear line around the object element is obtained, fixing the material at the moment when the opposing densities of the two elements match, and washing and drying the material. The first exposed material may be developed and fixed, and printed on to a second photographic material which latter is given the partial development, exposure to weak light and redevelopment treatments. To provide a line image of an object showing surface detail thereof exposure may be made with the object illuminated with a weak even light and the background illuminated so as to produce strong contrast thereto. In exposure sharp focus produces a fine outline. The original exposure may be effected directly by illumm ating a photographic material with the object upon it or by projecting, by means of an enlarger, an image of the object on to the material. Specifications 592,270 and 592,296, and an article in the British Journal of Photography, Vol. LXXXIII, No. 3980, pages 510, 511 are referred to.

Title: Improvements in or relating to the de-polymerisation of polystyrene
IPC: C07C4/22
Filed: 1939-02-16
Abstract: 525,276. Depolymerizing polystyrene. DISTILLERS CO., Ltd., PHILIP, T. B., STANLEY, H. M., and WOOD, W. L, Feb. 16, 1939, Nos. 5179 and 25234. [Class 2 (iii)] Polystyrene is depolymerized by a rapid heating of short duration by contacting the polystyrene with the body or surface of a heated material of high heat conductivity maintained at 550-700‹C. while preventing a static or sluggish state of contact. The polystyrene may be employed in either the crude or pure form. The heating may be carried out by feeding molten polystyrene into a mass of molten heating material such as a metal alloy or fused salt, and agitating the mixture or the polystyrene may then be projected on to the agitated surface, of the heat transfer material. Alternatively a solid heating surface such as a hot plate may be used particularly if used in conjunction with an agitating device such as co-operating scrapers or paddles, or by rotating the plate itself. The preferred reaction temperature is about. 650‹C. and it is essential that the time of contact should be short to avoid side reactions and the production of high boiling oils. The reaction may be carried out at atmospheric pressure, but an elevated pressure is preferred. Steam may be injected to remove the depolymerized products from the reaction zone. The polystyrene may be introduced into the reaction zone in the molten state or in solution. In the latter case the preferred solvent is the high boiling oil which is formed as a by-product of the depolymerization. In examples (1) Polystyrene of a molecular weight of about 60,000 in benzene solution is run into a vessel containing soft solder at a temperature of 615‹-620‹C. The mass is agitated by a stirrer. Under these conditions almost instant depolymerization is obtained without formation of coke ; (2) A benzene solution of crude polystyrene resin was fed into a vessel under the same conditions as used in example (1) except that a slightly higher temperature was used. No coke was formed and the product consisted of a mixtureof mono-styrene and α-methyl styrene. (3) The same materials were treated under the same conditions as example (2) except that steam was used to assist in removing the depolymerized products. (4) The same materials were used as in example (2) except that no lead alloy was present in the reaction vessel. If the process is conducted under the above conditions, but in the absence of efficient agitation coke is produced in amounts of 10 per cent. or more.

Abstract: 496,854. Recording and reproducing sound. ZEISS IKON AKT.-GES. Feb. 25, 1938, Nos. 6026, 6027, 6028, and 6029. Convention dates, Feb. 25, 1937, May 4, 1937, Aug. 3, 1937. and Dec. 24, 1937. [Class 40 (ii)] In a sound film recording or reproducing apparatus the grip of the film on the sound drum, when the tension becomes excessive such as during the starting period, is increased by providing a roller which, under the action of the film, presses it against the drum or against a further roller situated before it. The film, after leaving steadying rollers 4, Fig. 1, passes between a roller 5 and a roller 12 mounted on a lever 11 pivoted on a spindle 10. It then passes around the sound drum 3 to which is attached a flywheel 2 and thence in S form around rollers 6, 7 mounted on a link 9 pivoted on a bolt 8. During the starting period the increased tension in the film causes the link 9 to tilt in an anticlockwise direction against the action of a spring, which movement is communicated by an adjusting screw 13 to the lever 11, so pressing the roller 12 against the roller 5. Consequently the tension in the film around the drum 3 is further increased so bringing the flywheel 2 to its maximum speed quickly. The tension then decreases and the link 9 returns to its normal position. Alternatively a roller 16, Fig. 3, mounted on a lever 20 is caused to press the film against the sound drum 3 by communicating the movement of the link 9 through levers 17, 20 and an adjustable spring mounted stud 22. In a simplified form of this the roller 6 is caused to press directly on the sound drum, Fig. 5 (not shown), and in a further form, Fig. 6 (not shown), both this roller and the additional roller are used. In all cases movement of the link 9 is damped by an air-dash-pot device.
