Title: Improvements in or relating to colour photography and projection
IPC: G03B33/00
Filed: 1931-08-29
Abstract: 388,754. Colour photography and projection. HILGER, Ltd. A. and DOWELL, J. H., 98, Kings Road, Camden Road, London. Aug. 29, 1931, No. 24357. [Class 97 (i).] In the production of colour component images, particularly for kinematography, an imagedividing prism is combined w i t h cylindrical and spherical lens elements to produce two or more identical images from the same view-point, the images having different magnifications in the horizontal and vertical directions so that one set of companion images exactly fills one picture space on the film and the images are in close juxtaposition. In Fig. 1 the light is received by a cylindrical positive lens 12 and then enters a prism 1 having a semireflecting surface 3 dividing the beam into two parts, one of which after reflection by the surface 5 passes through a negative cylindrical lens 13 and a positive spherical lens 15, while the other is reflected at the surface 7, passes through lenses 14, 16 similar to the lenses 13, 15, and is deviated by a mirror 9, the images being formed side by side at 10, 11. The axes of the positive and negative cylindrical lenses may be parallel, or at right-angles, to each other, and the spherical lenses may be disposed between the cylindrical lenses instead of having the position shown. The spherical and cylindrical elements may be combined in such a way that at least one lens has a spherical face on one side and a cylindrical face on the other. The prism 1 may itself be provided with spherical or cylindrical surfaces instead of the plane entrance or exit surfaces shown. The images are projected on to a screen 22 through a system which corrects the distortion, such system consisting, for each image, of a spherical lens 23, Fig. 3, between cylindrical lenses 24, 25. The axes of the cylindrical lenses may be crossed, in which case the lenses are either both positive or both negative, or the axes may be parallel, in which case the lenses are preferably of opposite signs. Specification 349,107 is referred to.

Title: Transfer tapes
IPC: C09J7/20
Filed: 1972-05-24
Abstract: 1384423 Adhesive transfer tapes AVERY PRODUCTS CORP 24 May 1972 [28 May 1971] 24390/72 Heading B2E A pressure-sensitive adhesive transfer tape for applying adhesive to a substrate comprises (a) a carrier tape material having a release surface on at least a portion of one side and (b) a plurality of substantially non-contiguous segments along the length of the carrier tape in detachable adhesive contact with the release surface, the construction being such that after applying segments from the carrier tape to a given substrate the carrier tape can be detached from the applied segments whereby a transfer of segments from the carrier tape to the substrate is effected. In a preferred construction the carrier tape has release coating on both of its surfaces, the pressure-sensitive adhesive segments being on only one surface. In this construction the reverse side of the carrier tape has a back size having a lower adhesivity for the pressure-sensitive adhesive segments than the adhesivity of the pressure-sensitive adhesive segments for the principal release coating on the carrier tape. Alternatively a second release coating tape may be inserted between the convolutions. The width of the pattern of applied pressure-sensitive adhesive segments may be not co-extensive with the width of the tapes so that there are borders on one or both edges of the carrier tape which serve as guide(s) during dispensing of the tape from a suitable dispensing means. The carrier tape may be of paper, cellulose acetate, polyolefin or polyester. In one embodiment if a polyolefin tape is employed one surface may be corona treated so that it would function as a principal release surface and the non-treated surface would function as the backsize. The pressure-sensitive adhesive may be based on polyisobutylene, styrene - butadiene copolymers or ethylenevinyl-acetate copolymers. Tackifiers such as terpene resins, rosins, rosin esters, indene resins and alkyl-substituted aromatic resins may also be present. Butylated hydroxy toluene may be present as antioxidant. The pressure-sensitive adhesive segments may be applied by rotogravure printing, silk screen printing, or intermittent extrusion of an adhesive melt.

Abstract: 1,190,003. Photo-electric alignment error measuring. G.S.K. HONG. May 30, 1967 [June 1, 1966], No.24431/66. Heading G1A. An alignment error measuring device comprises a uniform light source illuminating a grid, a lens system, a second grid the position along the optical axis of which may be varied, and a photo-electric sensing means, the lens system being arranged to produce an image of the first grid in the plane of the second and the photo-electric sensing means being arranged to measure the light passing through the second grid. The second grid may be arranged so that in alignment half of the flux passing through the first grid passes through similarly dimensioned parallel grids of the second. The arrangement may include a telescopic arrangement for focusing the image of the first grid on to the plane of the second and the focusing may be automatic with servo loop control. A modification may employ grids, the bars of which are split into two groups and arranged in conjuction with two photo-cells connected in electrical opposition to produce a push-pull effect. The automatic focusing device relies on the position of a knife edge along the optical axis affecting the distribution of light to a pair of photo-cells connected in a differential circuit providing also an output in accordance with the total received flux for sensitivity control. Grids arranged in four quadrants may be used to assess alignment errors in two orthogonal directions. In a further modification the second grid may be replaced by parallel bar photo sensing elements.

Abstract: Dodecaborane carbonyls of formulae B12H10(CO)2 and H3O+B12H11CO-.pH2O, where p may be 2-20, are prepared by reacting a hydrate of H2B12H12 with at least 1 : 1 molar amounts of CO at 35-225 DEG  C. at or above atmospheric pressure, preferably at 500-1000 atm., and in a silver or monel lined reactor.  Inert solvents, and catalysts, e.g. Co2(CO)8, may be used. B12H10(CO)2 is isolated by sublimation or by extraction with a non-polar organic solvent, e.g. benzene, while H3O+B12H11CO- remains behind and is separated by adding aqueous Me4N+Clto precipitate Me4N+B12H11CO- which is treated with acidic cation-exchange resin; alternatively, H3O+B12H11CO- is first removed as above, and B12H10(CO)2 is obtained by acidifying the filtrate.  I.R. and N.M.R. spectra of B12H10(CO)6 are given.  The acid H2B12H12 is formed by acidifying a soluble, e.g. alkali metal, salt with aqueous or anhydrous HCl or with an acidic cation-exchange resin, to give hydrates on evaporation.  The salt may be prepared by reacting an alkali metal borohydride with diborane in an ether, e.g. diethyl ether or 1,2-dimethoxyethane, at least at 100 DEG  C. and under an autogenous pressure of at least 3 atom., and may be recrystallized from ether or tetrahydrofuran; hydrates are obtained by mixing with water, distilling off the solvent, and evaporating.
