Title: Improvements in electrophotography
IPC: G03G17/02
Filed: 1960-06-15
Abstract: A process for developing an image on a light-exposed photo-conductive copysheet having an electrically conductive backing comprises connecting the backing as cathode and electroplating metal on the light-exposed areas of the photoconductive layer and subsequently connecting the backing as anode and effecting electrolysis to produce a further layer on the plated image areas.  The photoconductive sheet, typically of the zinc oxide-in-resin type, may be exposed in the plating bath through the transparent walls, either through its base if this is transparent or if the base is opaque through a frame-like anode or a grid anode which is oscillated to avoid recording the grid pattern, plating development being effected simultaneously with exposure if desired.  The base, if not of non-conductive material such as cellulose acetate on which is coated a conductive metal film in contact with the photoconductive layer, is covered on its outer face with a sheet or coating of non-conductive plastic.  The image may be developed by the deposition of copper, silver or nickel as described in Specification 864,474.  The conductive layer or film of the backing is then connected as anode in a bath of a dye with a coloured anion which is deposited on the metal plated image which may also be oxidised simultaneously. Alternatively a colourless dye such as indigo white may be anodically oxidized to insoluble indigo on the metal image either by including it in an electrolyte or by coating the metal plated photo-conductive surface with it. A coloured image on a nickel plated layer may be produced anodically on a material on an aluminium backing by moving over it a sponge containing a dilute aqueous solution of sodium sulphite, p-nitrobenzyl cyanide and p-amino-diethylaniline, a -naphthol or ethyl aceto-acetate to produce magenta, cyan or yellow images respectively. Reference is made to using other oxidizable compounds such as pyrogallic acid. Electrophoretic deposition of negatively charged particles such as aqueous dispersions of aniline blue or indigo or of organic polymeric materials may be employed. For the production of lithographic plates, the metal plated image on a layer of zinc oxide in butadiene-styrene on an aluminium backing is electrophoretically coated as anode with polythene, polypropylene, PTFE, rubber, butadiene-acrylonitrile or -styrene, polyvinyl acetate, polystyrene or polyvinylidene chloride from aqueous dispersions. Coloured pigments, carbon black, or silica may be incorporated in the dispersed polymeric particles.

Title: Improvements in or relating to the manufacture of profiled or shaped wood parts including the absorption of synthetic resin solutions or other binding agents
IPC: D21B1/06
Filed: 1953-07-30
Abstract: 733,588. Treating wood. HERMAL HOLZVEREDELUNGSGES. July 30, 1953 [Aug. 2, 1952], No. 21115/53. Class 145. [Also in Group VIII] In a process for forming shaped wooden parts, such as building and furniture parts, window frames and Venetian blind slats, the wood has its fibres mechanically displaced substantially parallel to each other so that their transverse connection is extensively loosened or destroyed, is immediately immersed in a solution containing a binding agent and, if necessary, filling substances and is then deformed to the required shape. The fibres may be displaced by heavy beating or by passing the wood in a moistened, steamed or green condition once or several times between fluted rollers with the lengthwise fibres running approximately parallel to the flutes or alternately between fluted and smooth pairs of rollers. The wood is compressed during this treatment and its subsequent expansion in the impregnating liquid assists uniform absorption of the binding agent. To improve the distribution of the binding agent, the impregnated wood is pressed or treated between rollers which may be profiled to give the required final shape. Extrusion is stated to be an alternative method of forming shaped parts.

Title: Improvements in or relating to the manufacture of tissue-selective or specific healing agents
IPC: C07K16/06
Filed: 1935-07-29
Abstract: Serums which take effect on specific tissues or organs, but which are free from species-specific bodies, are prepared from tissues or organs which have been taken from an animal which has been completely bled and exhaustively washed out with isotonic saline solution, or from ordinary slaughterhouse material which has been thoroughly cleansed in the uncomminuted form with saline solution.  The material is then disintegrated, as by fine cutting in frozen condition, so as to break down the cell structure, extracted by saline solution, and the extract, after mechanically removing solid matter by settling or centrifuging, is injected intravenously into an animal of a species different from that from which the tissue or organ was derived, and a serum obtained from the animal in the usual manner.  The addition of disinfectants or the like is avoided, the extract or the serum being preserved, if necessary, by cooling or freezing.  According to examples a serum for reducing secretion of gastric juice is obtained by injecting an extract of the mucous membrane of the stomach of a dog into a rabbit or goat, and a serum which, by acting on the hypophysis, promotes assimilation of fat is obtained by injecting an extract of anterior lobe of hypophysis of an ox into a rabbit or goat. Horses may also be used as the serum-producing animals and serums which are active in respect of pancreas, kidney, thyroid or carcinoma may be prepared.  The Specification as open to inspection under Sect. 91 contains an additional example according to which sheeps' thyroids from a slaughterhouse are soaked, in disintegrated condition, with physiological salt solution and dialyzed, and the solution is diluted and centrifuged and used for injection into a rabbit or goat to obtain a serum for treatment of Basedow or Begbie's disease.  Removal of species-specific bodies from the extracts may also be effected by chemical or biological decomposition, as by fermentation, and the extracts may be purified by ultrafiltration, dialysis or electro-osmosis.  This subject-matter does not appear in the Specification as accepted.

Abstract: 457,214. Bomb-dropping sights; speedometers. BRONZAVIA SOC. ANON., 3, Rue Magellan, Paris. July 31, 1935, No. 21749. Convention date, July 31, 1934. [Class 92 (ii)] [See also Groups XIX and XX] Relates to optical ground-observation apparatus for aircraft in which an adjustable marker in the field of view, when coincident with the target, indicates the moment of release for a missile to hit the target. According to the invention, the marker 30 is adjustable for air-resistance on a guide member 24 maintained parallel to the axis of the aircraft, one end 28 of the guide being adjustable for height and speed of the aircraft radially along an arm 21 inclined to the angle of drift. The arm 21 is carried by a wheel 22 geared to rotate through the same angle as a wheel 4 forming part of a transparent disc having lines a which are set parallel to the observed direction of movement of the target by turning a worm 12. The angle of drift is read off by an index line b which remains parallel to the axis of the aircraft. The speed of the aircraft can be measured by observing the time taken for the target to pass between lines c on the disc. This time is obtained by the adjustment of clockwork 13 which rotates a mirror 15 to cause the image of an illuminated slit to move across the field of view at the same speed as that of the target. The clockwork and slit are mounted on a disc 5 geared to the disc 4 so that the slit is maintained parallel to the lines c. The marker 30, the disc 4 and the slit-image are all arranged in the field of view of a lens system 11, 31, 2 arranged for downward view. The Specification as open to inspection under Sect. 91 comprises also a prism system arranged in front of the lens 2 and adapted for viewing the target horizontally. The prism system is provided with several objectives each giving an image of a part of the field of vision and the whole provides an image of the complete route.
