Patent GB-2007378-A (GB)
Title: Photographic processing method
IPC: G03C8/08
Filed: 1978-09-25
Abstract: A method is described of processing an exposed silver halide photographic material by treating it with an image dye modifying/silver halide developing (dymodev) compound. The dymodev compound develops the silver halide latent image and becomes inactive but diffuses from the non-image areas to an associated image dye layer where it reduces the image dye to form a photographic dye image in the image dye layer. The use of the dymodev compound reduces the amount of silver required to form a photographic image. Examples of dymodev compounds are di-hydro derivatives of pyrazines and quinoxalines and certain metal ions such as chromous.

Title: Manual release of screw threaded fasteners
IPC: B25B29/02
Filed: 1978-11-07
Abstract: A method of and hand tool for the release of nuts or bolts which have become seized, for example due to high temperature operation, in which the shank on which the nut is threaded, or the bolt shank, is stretched by a small amount sufficient to break any thin film welds, and a spanner can then be turned sufficiently to 'start' the release of the nut. In one form, a bolt 1 is stretched by screwing a tool 9 into a threaded socket 7 in the bolt head 3 to compress a strut 8 extending along a clearance bore 6 in the shank axis. In another, a spacer 32 fits with clearance over a nut 20 and an integral portion 33 or a separate tensioner nut is threaded on a bolt end 18 and tightened to stretch the shank. Then a key 36 is inserted to connect spacer 32 to nut 20 and the nut is "started" using a spanner applied to the spacer. <IMAGE>
Patent GB-2034997-A (GB)
Title: Voltage difference detector
IPC: G01R19/00
Filed: 1978-11-17
Abstract: A circuit for detecting a potential difference between two conductors comprises first and second complementary transistors T1, T2 connected with their emitter-collector paths in series between positive and negative supply rails and having their bases coupled to the conductors respectively. A potential difference of appropriate polarity greater than about 1.4 volts between the bases will cause the transistors to conduct and a third transistor T3 senses the resulting current flow. Since the action of a transistor as a switch is independent of its collector-emitter voltage a common mode rejection range of the supply voltage minus 1.4 volts is achieved. To increase the threshold of detection an attenuator R4, R5 and R6, R7 may be included between the two conductors and the bases of the first and second transistors, and diodes D1-D4 may be connected to allow either polarity to be applied. An LED may replace transistor T3. <IMAGE>

Title: Process and dyestuff preparations for dyeing mixtures of polyester and cellulose fibres
IPC: D06P1/613
Filed: 1979-04-12
Abstract: The present invention relates to a process for dyeing fabrics or warp yarns of polyester fibres and cellulose fibres using disperse dyes and azo dyes that are water-insoluble and produced on the fibres, which comprises   (a) padding the material with an aqueous alkaline liquor that contains a coupling component,   (b) subsequently drying the impregnated material, (c) subsequently developing the dye with an aqueous acidic developing liquor that contains a diazo component and one or more disperse dyes, and   (d) drying and thermosoling the dyeing thus obtained.   In the past anionic dispersing systems have been used for the disperse dyes and these have reacted with cationic diazonium salts, resulting in precipitation and unsatisfactory dyeings. We have found that satisfactory results are obtained by using the disperse dye in a non-ionic dispersing system based on ethoxylated phenol-formaldehyde condensates in which the free hydroxyl groups may be alkylated. The present invention provides a dyeing process using this dispersing system and a dye preparation containing it.
