Title: An improved milk-tin pouring and closure cover
IPC: B67B7/86
Filed: 1929-12-06
Abstract: 344,456. Pouring devices for milk tins. KLAPPERSTœCK, F., 7, Wilhelm Hauffstrasse, Friedenau, and SCHROEDTER, V., 1, Denkstrasse, S³dende, both in Berlin. Dec. 6, 1929, No. 37504. Convention date, Dec. 6, 1928. [Classes 21 and 66.] A device for piercing pouring and vent openings in a milk tin, and adapted to serve as a cover for the opened tin, comprises two relatively rotatable parts 1, 2 joined by a pin 3, which is fastened to the upper part and which slides in a slot 7 in the lower part. To the lower part are attached a spout 19, and two depending tubular spikes 4, 5 which are pushed into the tin to form the pouring and vent openings. These openings are adapted to be closed by spring- actuated closure plates, provided on the upper part of the cover. The upper part 1 carries a handle so that a tin to which the device has been fitted may be used as a jug. The margin 6 of the lower part of the cover is scalloped to form four limbs which bear resiliently round the milk tin and firmly secure the cover to it. The end of each tubular spike 4, 5 is so cut away as to form 2 points of different length connected by cutting edges, one of which is shorter than the other, so that the cut-out portion of the tin is not completely detached from the tin but remains hanging downwards from it. A rubber ring may be placed over the spikes 4, 5 to seal the connection between the cover and the tin. The Specification as open to inspection under Sect. 91 (3) (a) describes the provision of a radial groove in the pin 3 and of an inwardly projecting tooth on the slot 7, so that when the tooth is engaged with the groove, further rotation of the upper cover causes the parts 1, 2 to roll on one another positively until the separation of the two parts is effected. This subject-matter does not appear in the Specification as accepted.

Abstract: 376,317. Colour photography. KISLYN CORPORATION, 14, Wall Street, New York, U.S.A.-(Assignees of Soc. Francaise Cinechromatique (ProcÚdÚs R. Berthon); Paris.) Jan. 7, 1931, No. 634. Convention date, Jan. 7, 1930. [Class 98 (ii).] In order to reduce the amplitude of oscillation required to be imparted to the mirror or other device which is used to eliminate the moire pattern produced on the copy when printing by contact or by projection from an original colour-record linear lenticular film upon a sensitive film of the same kind, the original is produced on a sensitive film which has a slightly larger number of lenticles per inch than the sensitive copy film, the two films being embossed on different cylinders having, say 103 to 105 lines per inch for the original film, and 100 lines per inch for the copy film. As, at the time of reproduction, the original film has already been subjected to shrinkage by treatment in the developing baths, the difference in pitch due to this shrinkage will be still further increased by the difference given during embossing, with the result that the moire pattern will be composed of bands disposed more closely together than is usual, and the amplitude of oscillation of the mirror or other device, necessary to produce the minimum displacement of the bands which will suffice to eliminate the pattern from the copy, will be correspondingly reduced. The printing devices described in Specifications 301,732, [Class 98 (ii), Photographic processes &c.], and 310,320, [Class 97 (i), Optical systems &c.], which employ oscillating mirrors, are referred to.

Abstract: 1370354 Developing images by vapour deposition HUGHES AIRCRAFT CO 24 Aug 1971 [10 Sept 1970] 39643/71 Heading C7F [Also in Division G2] A method of developing images formed on an actinically sensitive recording medium by exposure to actinic radiation comprises selectively vacuum vapour depositing a metal on to the latent image. Movable walls are located between the metal vapour source and the recording medium so that the thermal energy of the metal vapour is reduced by impingement on the walls as it approaches the recording medium. The metal deposited on the latent image is amorphous and forms a low specular reflectance high contrast, optically diffuse visible image. The recording medium may be glass, ceramic on plastics and the latent image is formed by selectively bombarding with electrons, ions or phatons. Metals with higher heats of sublimation than the metals used for development can also be used for forming the latent image by vacuum vapour deposition. The listed metals are Ag, Cu, Sn, Au, Cr, Ni, Ni-Cr, Sm, Be, Er, Pd, Fe, Co, Si, Ti, U, V, Rh, Zr, Ir, Mo, Nb, Ta. The vapour deposited metals used for developing the latent image may be Cd, Zn, Mg, Pb, Bi, Sb, In, Ag, Sn, Cu, Au. A low speed tape recording system incorporating a moving wall developer is shown in Fig. 11. Writing is effected by electron gun  358 which produces a scanned and modulated electron beam 360 which forms a nucleated latent image on the tape 352. The moving wall developer 356 comprises a metallized polyimide belt 362, a narrow development chamber slot 364 and Zn metal vapour sources 366, 368. The recording tape 352 may be aluminized paper coated with a mixture comprising ZnO, CuCl and a copolymer of butadiene and styrene.
