Title: Photographic Colour Diffusion Transfer Material and Process
IPC: G03C8/08
Filed: 1980-08-19
Abstract: The invention relates to the production of a proof photographic colour positive simultaneously with the production of a colour negative. Colour diffusion transfer materials are known in which a negative retained image is formed at the same time as positive colour transfer image. However, such negative images are not suitable as a source of colour negatives. We now provide a photographic material comprising a support, as least one light-sensitive, negative-working, silver halide emulsion layer and, associated with said layer an image- providing compound that, in the presence of an imagewise distribution of oxidised silver halide developing agent in alkaline medium, forms an imagewise distribution of a dye or dye precursor characterised in that two types of said compound are associated with said silver halide layer the first of which forms an imagewise distribution of a non-diffusible dye and the second of which forms a complementary imagewise distribution of a diffusible dye or dye precursor. The compound of the first type may be a colour coupler and the compound of the second type may be a redox dye releaser. The photographic material may be processed according to the invention of EPA Pub. No. 14594 or UK Application 8026282 or 8026283.

Title: Gold-coloured Silver cadmium nickel Alloy Coating and Electroplating Process and Bath for Depositing Same
IPC: C22C5/10
Filed: 1981-09-09
Abstract: A silver-cadmium-nickel coating alloy consisting of 6-10 weight percent cadmium 0.5-1 weight percent nickel, up to 2 weight percent indium and the balance silver has a gold-colour substantially equivalent to that of a 12-16 karat gold layer of similar thickness. The gold-coloured alloy coating can replace a 12 karat gold inner layer in a duplex coating having a 22 karat gold outer layer, and thereby provide substantial savings in gold. A highly alkaline aqueous cyanide plating bath is employed in the electroplating process in conjunction with increased current density to ensure that a critical minimum amount of cadmium is deposited in the alloy coating.

Title: Guiding Webs to Splicing Unit
Inventor: KONTZ ROBERT FRANKLIN
IPC: B65H23/32
Filed: 1983-04-12
Abstract: A pair of turning bars (19,20) are used to guide a web (B) to a splicing unit (S) where it is joined to web (A), the web roll (A) support being aligned with the splicing unit and the web roll (B) support being spaced therefrom. The turning bar (19) guides web (B) transversely to web (A) and turning bar (20) redirects the web (B) so that it travels parallel to web (A) towards the splicing unit (S). Turning bar (20) is movable from a position (as shown) below web (A) to a position overlying web (A) by pivoting it alongside web (A) raising it, e.g. using a pneumatic cylinder, and then pivoting it back over web (A). In use, web (A) can be spliced to the trailing end of web (B) by threading web (A) over web (B) to the splicing unit for joining. When web (B) is to be spliced to web (A), initially the turning bar (20) is relocated over web (A) and the web (B) is threaded around the bars, over web (A) and into the splicing unit for joining. After the latter splice is made, the turning bar (20) is lowered to its initial position. <IMAGE>
Patent GB-2120596-A (GB)
Title: Apparatus for forming structural sheets from fibrous biological waste
Inventor: DVORAK BOLEK
IPC: B30B11/26
Filed: 1983-04-21
Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.
