Patent GB-1234632-A (GB)
IPC: G03C5/30
Filed: 1968-09-05
Abstract: 1,234,632. Photographic dye-developer diffusion transfer process. EASTMAN KODAK CO Sept. 5, 1968 [Sept. 5, 1967], No.42323/68. Heading G2C. The invention resides in a method of producing a colour image by the photographic dye-developer diffusion transfer process in which a photographic material comprising a support and at least one light-sensitive silver halide emulsion layer which contains a dye developer or is contiguous to a layer containing a dye-developer, which has been exposed to a light image, is processed by allowing an alkaline liquid that causes the dye-developer to develop the latent image to permeate said layers and by allowing the residual, unoxidized, portions of the dye-developer to transfer imagewise by diffusion and in register to a receiving layer contained in a receiving material and in which there is present in the alkaline liquid an auxiliary silver halide developing agent of the formula: - each R and R 1  in said formulae being H, an alkyl group containing 1 to 4 carbonatoms which may be substituted, an alkenyl group, acycloalkyl group or a phenyl group. The auxiliary developing agent of the formula I, II or III is preferably formed before or during said permeation by hydrolysis by the alkaline liquid of a compound of the formula: - respectively, R and R 1  being as defined above. These latter compounds are preferably incorporated in the photographic material before said exposure, preferably in the outermost layer and preferably by coating the emulsion side of the material with a solution of the compound and removing the solvent e.g. acetonitrile or methanol. These compounds may be present at a concentration of 10 to 150 mg per square foot. The compounds use in the examples are 3, 7-bis (hydroxyethyl)- 2, 3, 4, 6, 7, 8-hexahydro-1, 5-dioxa-3, 7-diazaanthracene, 3, 6-bis(hydroxyethyl)-2, 3, 4, 5, 6, 7- hexahydro-1, 8-dioxa-3, 6-diazaphenanthrene, 3, 6-dimethyl-2, 3, 4, 5, 6, 7-hexahydro-1, 8-dioxa- 3, 6-diazaphenanthrene, 3, 6-diallyl-2, 3,4, 5, 6, 7- hexahydro-1, 8-dioxa-3, 6-diazaphenanthrene, and 3-hydroxyethyl-6-hydroxy-2, 3, 4-trihydro-1-oxa- 3-azanaphthalene. The heterocyclic compounds may be incorporated in a layer of the receiving material before said processing so that it dissolves (and hydrolyses) in the alkaline aqueous liquid before said permeation. The colour prints resulting from the process of this invention have low minimum densities and the auxiliary developing agents have good resistance to aerial oxidation.

Abstract: 1,238,980. Centrifugal spreader. VOGEL & NOOT A.G. 17 Dec., 1969 [18 Dec., 1968], No. 61587/69. Heading A1D. A centrifugal spreader comprises one or more spreading discs 13 beneath an outlet cup 4, a valve 7 operable by a lever 16 which is movable with respect to a scale 17, means 24 for holding the lever in any selected position and a lever 6 for rotating the outlet cup about a vertical axis to control the segment into which material is scattered. A shield 23 masks the spreading discs 13 from above and a baffle 5 masks a segment of the circumference of the discs. The baffle and shield are connected to the outlet cup to rotate therewith. The outlet cup is provided with three equi-angularly spaced flanges (8), Fig. 2 (not shown), which overlap the edge of a disc 3 which has three corresponding notches (9), Fig. 2 (not shown), to allow the cup to be released when in a particular angular position. One of the flanges is spring loaded with a wing nut to adjust the compression of the spring. The hopper 1 may be removed from the implement frame 27. The handle 16 is connected to the valve 7 by means of a flexible cable 14 and a spring 15 acts to close the valve.

IPC: B05D5/06
Filed: 1967-09-15
Abstract: 1,257,301. Moulding sheets and panels. M. A. E. RHIANDO. 16 Dec., 1968 [15 Sept., 1967], No. 42191/67. Heading B5A. [Also in Division B2]-  Sheets or panels having a granular coating for use as constructional or decorative elements in the building industry are produced by applying a layer of a settable binding material to a moulding surface and causing an excess of granular material to flow across the surface of the surface in such manner that the weight of excess granules causes some of the granules to become embedded in the binding material to form a coherent coating. The flow of granular material across the surface may be produced by tilting the moulding surface alternately in opposite directions relatively to the horizontal or by rocking the moulding surface backwards and forwards. The granules may consist of ceramic granules which have been pigment coated and fired, particles of glass, enamel, or granite chippings, marble or other mineral aggregate which may be coated with a glaze or a resin such as polyurethane, melamine or polyesters. As shown in Figs. 3 and 4 base member 26 is formed with a well 54 lying below the level of granular material receiving troughs 32, 34 which well receives a female mould 50, the surface 52 of which has been sprayed with a binding material. Preferably before being sprayed with the binder the surface 52 is provided with a release layer to which the binder will not adhere, e.g. a polytetrafluoroethylene coating or a thermoplastic polypropylene. The well 54 may be sufficiently deep to accommodate moulds 50 of different depths, the mould being packed from below to bring its peripheral surface in the same plane as the base of the troughs 32, 34 so that granules passing across the mould surface will not meet any obstruction. When the mould 50 is in correct position in the well 54, the base member 26 is rocked about the shaft 24 so that the trough 32 is tilted to an upper position and excess granules flow across the mould surface and are collected in trough 34 in its lower position. The reverse flow of granules takes place with reverse tilting of the base 26. The mould 50 is then passed through a spray booth 46 where a coating of binding material seals- and waterproofs the granular coating. When the coating of binding material has hardened beyond the tack point, the mould 50 is removed and placed in a press 56 having a correspondingly shaped male mould 58. The granular layer is then covered with a mat of glass fibres above which is applied a polyester resin including a catalyst and hardener. The press is then operated so that the two moulds come together and distribute the resin over the mould surfaces and forces the fibre mat to the shape of the granule coating covering the mould surface. When the laminate is sufficiently cured, the moulds are separated.
