Title: Improvements in or relating to the formation of thin films
Inventor: HILL RAYMOND THOMAS JOSEPH
IPC: C23C14/26
Filed: 1960-11-29
Abstract: 918,382. Coating by vapour deposition. GENERAL ELECTRIC CO. Ltd. Nov. 21, 1961 [Nov. 29, 1960], No. 41076/60. Class 82 (2). In a process of vapour depositing a film such as a luminescent material on to a substrate, the filmforming material in powder form is held in a container which is vibrated, and a potential difference is maintained between the powder and a heating element, which is located between the powder and the substrate, and a heating current is simultaneously passed through the element to cause vaporization of the powder which is attracted to the element from the container. As shown in the Figure, when used for applying a luminescent film to the internal wall 3 of a cathode ray tube a vessel 5 supporting a metal container 7 containing powdered luminescent material 7 is mounted on the end of a flexible iron rod 8 which is fixed at its lower end to a bung 4 which seals the cathode-ray tube. The free end of the rod 8 and thus the powder 7 is vibrated by an electromagnet 9 operated via switch S1 and an alternating current of 50 c.p.s. A heating element 11 supported above powder 7 is connected via switch S2 to a heating current 12, and also via switch S3 to the positive terminal 13 of a high-voltage D.C. source, the negative terminal 14 of which is connected to container 6. The cathode-ray tube is evacuated via 15 and switches S1, S2, S3 are closed whereby the powder 7 is vibrated and attracted to the heating element 11, evaporation is effected and deposition of the material takes place on surface 3.

Abstract: 922,301. Conical mills; agitating pulps. NOBLE & WOOD MACHINE CO. Nov. 21, 1961 [Dec. 5, 1960], No. 41630/61. Classes 59 and 86. [Also in Group VIII] Pulping apparatus comprises a tank 12, the bottom of which is formed with a circular opening within which is mounted a circular rotor 10 in such manner as to.leave an annular orifice 26 for the discharge of pulp, the opposite walls of the orifice co-operating to have a refining action on oversize pieces of pulp. The walls of the orifice may be vertical or inclined and may be shaped to assist the refining action by having vertical ribs with sharp or rounded edges, the latter being illustrated in Fig. 6. The ribs of one element may be set at an angle to those of the other element. In other forms, horizontal ribs may be provided, Figs. 7, 9 and 10. Where the orifice walls are inclined and the rotor 10 is mounted for vertical adjustment, the width of the orifice may be varied. The apparatus may be employed for either batch or continuous processing. Two separate fields of motion of the pulp stock are created by the rotor 10, larger pieces of material being given an upward thrust by impeller blades 22 while smaller pieces tend to flow radially assisted by ejector blades 24 until they pass into the outlet orifice 26. Scraping members 46 are mounted on the rotor 10 to prevent obstruction of the orifice 26.

In a method of forming stainless steel clad carbon steel sheet a pack is formed having outer plates 11, 12 of stainless steel which project beyond a core 10 of the carbon steel and which are sealed to form a cladding box by welding carbon steel insert bars 13 around the edges with a first weld 15, which may be a weld using the M.I.G. process, followed by a second weld 16 by the submerged arc process. A space 10a is left between the core and one of the bars. The pack is then evacuated, or filled with a non-oxidizing gas at sub-atmospheric pressure, heated to 1950-2300F. and rolled to weld the outer plates to the core. In a modification, Fig. 3, a four-ply pack has outer carbon steel plates 30, 31, and a core formed by a pair of stainless steel plates 32, 33 separated by a parting compound 34 to prevent welding of the stainless steel plates during rolling. The parting compound comprises one part lacquer, two parts thinners and one to one and a half parts chromium oxide powder of 240 to 400 mesh (U.S. screen), and during the heating process the lacquer breaks down to form an inert atmosphere within the pack. For welding the bars to the pack, welding rods of SAE type 1006 to 1010 carbon steel are used if the external sheets are carbon steel and SAE type 304 or 308 stainless if the external sheets are stainless.

Abstract: 1,169,960. Moulding porous bodies. DOULTON & CO. Ltd. 23 Sept., 1968 [21 Sept., 1967], No. 43072/67. Heading B5A. Porous, fluid-permeable bodies are made by wetting a mass of synthetic polymeric material in particulate form with a solvent comprising a material-dissolving and a material-inert component so that the surfaces of the particles are softened and they stick together at their points of contact and removing the solvent to leave the polymer mass in a coherent porous form.. The polymeric mass may contain a filler and may be wetted by pouring, spraying or dipping. The solvent may be removed by vacuum stripping through a porous wall of the mould, centrifuging (e.g. for making pipes) or flash heating. A stream of drying gas may be passed through the material to complete the removal of solvent. In. the examples, porous bodies are made from polystyrene beads using ethylene dichloride and isopropyl alcohol as active and inactive solvent and from nylon granules using formic acid and water as solvent mixture. The bodies may be used for the filtration of liquids or gases and in fluidization operations.
