Title: Improvements in or relating to photographic diffusion transfer procedure
IPC: G03C8/06
Filed: 1960-11-03
Abstract: 902,314. Photographic diffusion-transfer procedures. INTERNATIONAL POLAROID CORPORATION. Nov. 3, 1960 [Nov. 23, 1959], No. 37838/60. Class 98 (2). To produce silver transfer images of improved stability and reduced stain, development is effected with a first developer which may .be contained in the photo-sensitive element and which does not cause transfer to the image receiving stratum or element, and the transferred soluble silver complex is reduced with a second, volatile, silver halide developing agent. A product for the purpose has an element including a silver halide emulsion and the first developing agent, a rupturable container with processing composition including the second developing agent, a silver-receptive imagereceiving element, and silver halide solvent in one of the elements or in the composition. Preferably the composition is such as to produce a solidified layer on the receiving layer, but it is also contemplated to perform the process to cause such layer to adhere to the developed negative. In a first example, an exposed emulsion is processed in a standard metolhydroquinone developer and then processed again in the dark and without being fixed in a viscous solution comprising sodium hydroxide, thiosulphate and carboxymethyl cellulose with N,N-diethylhydroxylamine as the second developing agent whilst superposed on an imagereceiving element, which latter with the solidified layer of processing composition is later stripped off the emulsion. A second example uses an emulsion overcoated with a gelatin solution containing 4<SP>1</SP>-methyl-phenyl-hydroquinone and the transfer is effected with the viscous solution of Example 1 only, and a third example repeats this but with omission of the N,N-diethylhydroxylamine to show, for comparison purposes, only a pale positive image. The use of other volatile hydroxylamines for the procedure is indicated. Specifications 684,592, 752,409, 775,322, 789,837 and 902,313 are referred to.

Abstract: A polyfluorinated ethylene polymer article (e.g. polymers of fluorinated ethylene or copolymers of fluorinated ethylene or copolymers of fluorinated ethylene with ethylenically unsaturated monomers) has a layer of metal bonded to the surface thereof by the following process.  The surface is abraded and washed with water to ensure chemical cleanliness, contacted with a muddy black solution of sodium in liquid ammonia (i.e. 10-15% of sodium or more) for 1-1.5 minutes, warmed in air or an atmosphere containing at least 20% oxygen to complete the reaction, and then pickled in concentrated HNO3, HCl or a mixture of these followed by light surface abrasion. The surface is then senisitized by treatment with a stannous chloride solution containing fluoride ions, followed by hypophosphite reduction and washing, and seeding by hypophosphite reduction of Au, Pd or Pt chloride followed by electroless or auto catalytic deposition of Cu, Ag, Au, Co or Ni.  The article is then rinsed and given a dip in dilute acid containing fluoride ions. Electrodeposition of a metal (e.g. Ni) is then carried out in two stages, the first at a temperature below 80  DEG F. to give a coating thick enough to withstand expansion of the polymer at 165  DEG F. and the second at a higher temperature to complete the coating.

In a travelling band filter such as an inward flow, rotary vacuum drum filter (Fig. 1, not shown), the endless filter web 13 has edge beads 21 which are engaged, at some location where the web is not otherwise supported, by means (19) which pull the web transversely against each other and maintain its alignment. In Figs. 9-12, the means each comprise two pairs of bead engaging wheels 62, (63) mounted on a common bar 67 which is urged outwards, to tension web 13 transversely, by spring 32, adjustable in compression by wheel 31. Bar 67 may be pivoted to shaft 73 at various points (Figs. 10, 11, not shown) to vary the relative forces exerted on the beads by wheels 62, (63). The springs 32 urge the web towards a central position where their compressions balance. Springs 69 urge pairs of wheels together and allow bead 21 to be pulled out from the wheels to protect the web from excessive transverse forces. In other embodiments, one pair of wheels on each edge of the web are used (Figs. 4, 5, 7, not shown), or wheels are replaced by bead engaging blocks (Figs. 2, 3 not shown). Instead of springs 32, the bead engaging means on opposite edges of the web may be connected by cables to a common free hanging weight (Fig. 8. not shown), which tilts in response to spurious web movement thereby shifting its centre of gravity to restore the web to a central position. Fig. 6 (not shown) illustrates how bead 21 may be integral with an impervious edge strip 20 of the web, edge member (60) of vacuum drum (12) being perforated at (61) so that the vacuum holds the strip 20 down on the member (60). .
