IPC: B32B17/10
Filed: 1930-04-07
Abstract: 347,455. Compound transparent sheets. DUPLATE CORPORATION, 2200, Grant Building, Pittsburg, Pennsylvania, U.S.A.-(Assignees of Sherts, J. H.; 852, Broadview Boulevard, Brackenridge, and Hamill, R. E. ; 609, 10th Avenue, Tarentum, both in Pennsylvania, U.S.A.) April 7, 1930, No. 11009. Convention date, April 9, 1929. [Class 140.] The edges of compound transparent sheets composed of glass and pyroxylin or like plastic are treated by heating under pressure in a liquid preferably a solvent for the plastic so that the plastic is softened and firmly united to the glass. The sheets 16 are treated in a. rubber-covered tank 17 of the liquid which is enclosed in a pressure-chamber 1 secured in the floor 2 and heated by water to 250‹ F. at a pressure of 150 lbs. per sq. inch. The water is then cooled and the pressure released at 140‹ F. The sheets may be carried in a rack and the solvent liquid used as the pressing liquid. The cover 7 is secured by cam-shaped lugs 8, 9 on a gasket 11. The tank 17 is supported on a table 5 by a plunger 4 which is raised by liquid admitted at 6. The preferred solvent is that known under the trade name Carbitol, which is prepared by heating ethyl alcohol and ethylene oxide under pressure till reduced to a mixture of ethyl alcohol, ethylene glycol mono-ethyl ether, di-ethylene glycol mono-ethyl ether or " Carbitol," and glycol. Carbitol is left after distilling above mixture. Other high-boiling point solvents or plasticizers for the plastic sheet may be used, such as butyl carbitol, dibutyl phthalate, di-methyl phthalate, tricresyl phosphate, triphenyl phosphate, cyclohexanol, amylacetate, dichlor-ethyl ether, zylol, diethyl perlmitate, diethyl ether, or mixtures thereof. Also non-solvents such as paraffin, castor oil, glycerine, linseed oil, solar oil, mercury and other substances may be used. Sheets on which edge-separation of the component sheets has occurred may be repaired by treating with a non- volatile solvent for the plastic. When the plates are to be exposed to moisture a substance non- miscible with water should be used in place of carbitol.

Abstract: 994,332. Wrapping machines. MOLINS ORGANISATION Ltd., D. H. YOUNGMAN, and A. E. WARD. March 20, 1964 [March 20, 1963], No. 11062/63. Heading B8C. A wrapper blank 1A (Fig. 3) is drawn upwards from a support 8 by grasping means 14, so that it is held in front of a block-shaped article 11, the article then being moved against the blank as wrapping commences. In one form the plunger 12 pushes the article 11 against a vertical wrapper so as to pull the wrapper from the grasping means 14, and then wrapper and article are forced between the two plates 9 and 10. A roller 20, supported on the lever 21, is moved to the left to tension the wrapper as it is drawn upwards. The grasping means 14 may comprise mechanical or suction grippers, or an adhesive coated roll. If grippers are used there is provided means 39-42 (Fig. 1) for applying a line of adhesive to the leading end of the blank, and if an adhesive-coated roll is used the same means can be used to apply adhesive to the roll. Suction or mechanical grippers may be controlled so as to release the wrapper automatically when the package is moved against it, or the grippers may move downwards still holding the edge of the blank as the wrapping starts. The wrapper blanks 1A (Fig. 1) may be cut from a web 1 by a blade 6A which co-operates with an edge 7. As the wrapper is cut at the edge 7 it tends to slide along the support 8 and overlap the trailing end of the previous wrapper, so that as the leading edge of a wrapper is grasped and pulled upwards by means 14, the trailing edge drags along the leading edge of the next wrapper. Alternatively the web may be fed perpendicularly to the direction of motion of the packages, and the severed blanks fed sideways on to the support 8. In the form where mechanical grippers are used a pair of feed rollers and a curved guide are provided to feed the leading end of the blank into the grippers.

[Also in Group XXII] In a method of producing a thin porous element with stiffening ribs on one face, comprising mechanically working a thin metal sheet to form ribs on one face, subjecting the other face to an oxidizing treatment to transform into oxide the whole thickness of the metal in the regions between the ribs, but leaving the ribs unoxidized, the element is given a tubular shape before the oxidizing treatment. The resulting porous tubular element is intended more particularly for the separation of isotopes by gaseous diffusion and may be made of a sheet from 60 to 300 microns thick of a metal or alloy which forms a strongly adhering oxide layer such as aluminium, magnesium, chromium, nickel, tantalum, titanium, vanadium, zirconium, hafnium and alloys thereof. The sheet is formed into a tube 1 of circular or polygonal crosssection placed over a mandrel 5 while the ribs 3 are formed as by rolls 6 with teeth 4, Fig. 3, or by dies 7, Fig. 5. If the resulting ribbed element is of polygonal section, it is made round by applying an internal fluid pressure of 2 or 3 kgs. per sq. cm. The oxidizing of the tube is preferably carried out by anodic treatment, the ends of the tube 1 being connected to a tank and electrolyte 11 circulated through it while an electric current is passed between the tube and a central rod 10. In an example, the tube is of an alloy of aluminium and magnesium containing 3% magnesium, is 15 mm. internal diameter and has a wall thickness of 0.04 mm. between the ribs which project 0.11 mm. The electrolyte is a 7% aqueous solution of oxalic acid at 30 C., the rod 10 is of molybdenum and the current density 1.2 amps. per sq. decimetre of tube surface. 2.9 ampere hours was required to oxidize the required thickness of 0.04 mm.

Abstract: 309,552. I. G. Farbenindustrie Akt.- Ges. April 12, 1928, [Convention date]. Addition to 299,721. Samples furnished. Naphthalene derivatives.-Acid wool dyes of the kind described in the parent Specification are obtained by the action of reducing agents in aqueous solution on nitronaphthalimides or their N-alkyl, N-aralkyl or N-aryl derivatives. If un- Sulphonated bodies are used as parent materials, the reducing agents employed are such as simultaneously cause the entrance of a sulpho-group, for example, a hydrosulphite or bisulphite. Water-soluble orgarnic solvents, such as alcohol, are advantageously added to the aqueous solutions. The parent materials may be made by oxidizing nitro-acenaphthenes or by directly nitrating naphthalic anhydride, and condensing the resulting nitro-naphthalic anhydrides with ammonia or an aliphatic or aromatic amine. In an example, 4-nitronaphthalic-N-methylimide is reduced with hydrosulphite; the product dyes animal fibre in very even clear yellow tints; the methylimide may be replaced by the corresponding ethyl- or phenyl-imide, and the hydrosulphite by bisulphite. The Specification as open to inspection under Sect. 91 (3) (a) includes further examples in which (1) 4-nitronaphthalimide is reduced with hydrosulphite, the product dyes wool a greenishyellow tint. and (2) 4-nitro-1 : 8-naphthalic-4<1>-sulphophenylimide is reduced with hydrosulphite; the product dyes wool a clear yellow tint.
