Title: Improvements in or relating to the deposition of metals
IPC: C23C14/20
Filed: 1941-09-03
Abstract: 551,757. Coating with metals. ALEXANDER. P., CRANSTONE, E. L., and VAPCO, Ltd. Sept. 3, 1941, No. 11279. [Class 82 (ii)] In a process for depositing a film of aluminium or magnesium with a bright surface on a support of paper, material known under the Registered Trade Mark, "Cellophane" or other moisture absorbent material, the surface of the support on which the metal is to be deposited is exposed to radiant heat in a vacuum for a period less than that required to deprive the material of its moisture content and then, without prolonged exposure of the material to the atmosphere, the deposition of the metal is effected on the surface by thermal evaporation in a vacuum, while preventing the appreciable deposition on the other surfaces of the support. The strip 4, Fig. 1. is wound from a spool 5 on to a spool 6 operated by a clockwork motor 7, both spools being mounted in a chamber 1 which is evacuated through a hole 2. The strip 4 in passing from the spool 5 to the spool 6 is heated by an electric heater 3. The spool 6 is now transferred to a chamber 8 evacuated through a hole 2 and as the strip 4 passes from the spool 6 to the spool 9 it is exposed to the vapour of metal from a wire 12 of such a metal which is fed from a spool 13 of wire through rolls 15 driven by a clockwork motor 14 on to a heater 11 which may be a tungsten rod heated by an electric current. To prevent the vapour from striking the uncovered surface of the material 4, the heater 11 is partially surrounded by a screen 16. A device of the kind described in Specification 513,257, is employed to facilitate maintenance of the vacuum, this device consisting of a plate 17 of aluminium insulated from the chamber 8 by insulators 18 and connected by a wire 19 to a source of electrical high tension. Previous to the starting of the thermal deposition an alternating electrical discharge is maintained for a short time between the plate 17 and an aluminium casing, e.g. the screen 16, surrounding the heater 11. In a modification the chambers 1, 8 are combined in a single vessel divided by a partition, the heated strip passing from the spool 5 past the heater 3 and through a slot in the partition and past the heater 11 and then wound on the spool 9. In a further modification, the coated strip passes through a second slot in the partition on to the spool 9 which is placed in the same compartment as the spool 5. Specification 485,965 also is referred to.

Abstract: 377,237. Supporting and propelling aircraft. MAcCASKIE, T. M., 6735, St. Lawrence Avenue, Chicago, U.S.A. April 22, 1931, No. 11978. [Class 4.] An aircraft is propelled and in some cases supported by forcing air through a tube or tubes having a restricted passage near both ends, by means of a propeller arranged in one of the restricted passages. Alternatively a propeller on an axis at right-angles to the tube axis may be arranged in a tube having a restricted passage at one end. Fig. 1 shows an aeroplane having a tube 10 built into the fuselage, the forward end of the tube being outwardly flared in front of a constriction 12 and the rear end flared aft of a restricted passage 17. Between the constrictions 12, 17 is an enlarged portion 16 of greater diameter than the rest of the tube. Mounted near the constriction 12 is a fan 13 on a vertical axis driven by an electromotor or an internal-combustion engine 14 placed outside the tube. The fan which may have a heavy strengthening plate on its blades acts as a gyroscopic stabilizer for the machine. From the middle of the part 16 to the rear end the tube is rifled or provided with helical vanes 19 to produce a rotary discharge of air. The exhaust gases from the engine may assist this discharge. Fig. 3 shows a modification wherein the air is forced through the tube by a propeller 13 arranged at the constriction 12 and driven by an electromotor 14 supported by helical blades 15. Four similar tubes set vertically as shown may be provided for lifting the machine vertically. The electromotors may also be supplied from a generator 32 driven by an engine 33. Instead of a single tube in the fuselage a series of smaller similar tubes may be secured beneath the main plane.

Title: A process for the manufacture of polymerisation products
IPC: C08F20/14
Filed: 1941-09-22
Abstract: In the polymerization of methyl methacrylate a mixture of monomer, water and a dispersing agent is agitated with or without heat to form a dispersion and also subjected to polymerizing conditions (light, heat and/or catalysts) so that a partial polymerization occurs, and thereafter the polymerization of the dispersion is allowed to continue without agitation until the polymer separates in granular or globular form; where heat is applied, the mixture is cooled, or allowed to cool, after agitation is stopped.  Other substances, e.g. dyestuffs, plasticizers, may be added to the mixture.  The proportion of plasticizer should not exceed about 10 per cent of the weight of methyl methacrylate.  Preferred dispersing agents are a naphthalene sulphonic acid-formaldehyde condensation product (sold under the Registered Trade Mark "Belloid"); the alkali salts of sulphated aliphatic alcohols containing at least 8 carbon atoms in the molecule, e.g. sodium lauryl sulphate and the materials sold under the Registered Trade Marks "Ocenol" paste and "Lanette" Wax SX; Marseilles soap; sodium isobutyl and isopropyl naphthalene sulphonates; Turkey red oil; and triethanolamine and its esters.  It is preferred to use at least 5 per cent of the dispersing agent, e.g. 20-50 per cent calculated on the weight of monomer unless a viscosity increasing substance, e.g. sodium silicate, has been added when less may be used. Specified catalysts are benzoyl peroxide, hydrogen peroxide, ozone and oxygen.  The process may be carried out under increased pressure.  In the examples: (1) a solution of benzoyl peroxide and dibutyl phthalate in methyl methacrylate was dispersed in a dilute aqueous solution of "Belloid".  The mixture was heated with agitation to 83.4  DEG C. and maintained there for 15 minutes when it was allowed to cool and agitation then stopped.  After standing 12 hours the particles of polymer were separated, washed and dried; (6) an aqueous dispersion of sodium lauryl sulphate was used and the mixture heated to 75 DEG  C. for 5 minutes; (7) an aqueous dispersion of triethanolamine was used and the mixture heated to 85 DEG  C.; (8) "Lanette" wax SX was dissolved in monomer and benzoyl peroxide, and the mixture dispersed in water, it was heated to 88 DEG C., allowed to fall to 80 DEG  and held there for 15 minutes.  After standing 10 hours the granular polymer was processed as before; and (9) "Ocenol" paste was used.  In all examples it is preferred to wash the product with hot water. Specifications 358,534 and 374,436 are referred to.
