IPC: G03C7/14
Abstract: 489,823. Colour photography. LASSUS ST. GENIES, A. H. J. DE. Oct. 25,1937, No. 29140. Convention date, Nov. 5, 1936. Addition to 470,801. [Class 98 (ii)] The method of and apparatus for reproducing lenticular films as claimed in the parent Specification is adapted to the printing of copy films, the lenticulations of which are not parallel to those of the original film, by rendering the angular aperture of the luminous beams illuminating the copy film independent of that of the illuminating surface and of the copying objective and thereby effecting the spreading of the microscopic image spots projected on the copy film, by means of a plurality of auxiliary optical systems mounted in a screen movable in front of the copy film, each of which transmits rays from a partial image. The films may be curved to compensate for the tendency of an additional optical system adjacent the original film to distort the macroscopic image on the copy film. In the production of a copy film carrying a sound track, the film being arranged so that its centre is displaced laterally with respect to the optical centre of the copying system, a prism for compensating for the lateral displacement of the image on the copy film is associated with the optical systems in the screen movable in front of the copy film. An optical system composed of three short focus concave cylindrical may be placed in a screen movable in front of and in the immediate vicinity of the copy film. In a modification, Figs. 7 and 8, the optical system comprises three sections, the two outer comprising three prisms p with oblique lines of separation, and three parallel-faced glasses g, and the central section of plain-glass, in addition to the three cylindrical lenses. As shown in Fig. 10, D is an opaque screen having a window d, the form and dimensions of which correspond to the image of the view-taking filter. The screen D is illuminated by a lamp and the window d comprises a diffusing surface constituting the active surface of the luminous source. D<1> is a similar opaque screen similar to D arranged within the copying objective O. F and F<1> are the original and copy films, and A, B are auxiliary lenses on both sides of the original film F. Rand R are movable screens having slots S, S<1> parallel to the lenticulations of the original film F and animated by movements perpendicular to their lengths. A third opaque screen R<11> with a window is moved in the immediate vicinity of the copy film F<1>. The curvature introduced by the auxiliary lens B is corrected by giving the original film a curvature about a transverse axis and the copy film a curvature about a longitudinal axis. The distances between the films F, F<1> and the slots S, S may be varied. As shown in Fig. 15, a prism P<1> is combined with the concave lens U<1> mounted in the screen R<11>. Specification 482,690 is referred to.

Abstract: 1,241,614. Gamma flux detector. ATOMIC ENERGY OF CANADA Ltd. 17 Oct., 1969 [29 Nov., 1968], No. 51175/69. Heading H1K. A γ-ray detector has an emitter wire 1 of zirconium or of a zirconium base alloy, the surface of the wire being oxidized to provide a thin coherent insulating layer 3 separating the wire from a coaxial collector sheath 2 of a different metal. Irradiation with γ-rays produces a current through the ammeter 4 because of the different electron emissivities of the emitter and collector metals. The emitter material may be (a) zirconium; (b) 1.2-1À7 wt. per cent Sn, 0À07-0À2% Fe, 0À05-0À15% Cr, 0À03-0À08% Ni, balance Zr; or (c) 1À2-1À7 wt. per cent Sn, 0À18-0À24% Fe, 0À07-0À13% Cr, balance Zr. The collector material may be (a) titanium; (b) aluminium; (c) chromium base alloys; and (d) nickel base alloys such as one containing 77 wt. per cent Ni, 15% Cr, 7% Fe, 0À25% Si, 0À2% Cu, and 0À08% C. Aluminium is activated by neutrons and so such detectors may not be used in mixed neutron and gamma radiation: for the same reason the other materials should contain less than 0À1 wt. per cent Co and less than 0À2 wt. per cent Mn; these elements commonly occur as accidental impurities. The emitter wire is oxidized and fitted within an oversized collector sleeve and the assembly swaged or drawn. A length of the resultant detector has the collector sleeve sealed (by fusion) over a zirconia powder mass 17 and is connected to a mineral insulated cable by a welded metal sleeve 12. A split sleeve 9 of polycrystalline alumina extends over the oxidized emitter wire 1 to prevent the cable core 6 attached to the oxide-free end of the emitter 1 from shorting to the outer.

Abstract: 1510420 Polysiloxane/polycarbonate copolymers BAYER AG 8 Dec 1976 [11 Dec 1975] 51209/76 Heading C3T A process for the production and working up of a SiOC-linked polysiloxane/polycarbonate copolymer comprises reacting an alpha,#-dihalogenopolysiloxane, preferably an alpha,#-dichloropolydimethylsiloxane, with an alpha,#-dihydroxypolycarbonate, preferably derived from 2,2-bis- (p-hydroxyphenyl)propane, in the presence of an amine, e.g. pyridine or triethylamine, and an organic solvent and subsequently separating off the copolymer from the reaction mixture by subjecting the reaction mixture to steam distillation. Suitable organic solvents are chloro- and dichloro-benzene, toluene and xylene. The working up of the reaction mixture may be carried out either continuously or discontinuously. In the working up the amine hydrohalide formed during the reaction may be separated off and washed out and the copolymer solution then subjected to steam distillation. Alternatively the entire reaction mixture may be metered, e.g. by dropwise addition, spraying or atomizing, into water rendered alkaline to a pH of 7-8 and separately feeding in steam; or the entire reaction mixture can be fed in together with steam into the water at a pH of 7-8. The aqueous phase may contain surface-active agents. After removal of the solvent the copolymer is left behind in particulate form, which may then be dried and further comminuted. In Example 1 a block copolymer isprepared by reacting an oligocarbonate of the formula with an alpha,#-dichloropolydimethylsiloxane in the presence of pyridine using chlorobenzene as solvent. The resultant copolymer solution is then added dropwise to an aqueous NaHCOa solution while simultaneously passing in steam. The copolymer precipitates and when the addition is complete further steam is passed in. The particulate copolymer is filtered off and dried and when cast from a CH2Cl2 solution it forms a soft clear elastic film.
