Patent GB-1066509-A (GB)
Title: Improvements relating to copying processes
Inventor: GAMES ABRAM
IPC: B41C1/06
Filed: 1962-12-31
Abstract: 1,066,509. Printing processes. IMAGIC PROCESS Ltd. Dec. 30, 1963 [Dec. 31, 1962], No. 49105/62. Heading B6C. In a method of producing a copy of an original design in which an image is formed on a copy sheet by the evaporation of an oil over areas representative of the original design and its condensation on the copy sheet a mirror image is formed on the underside of an opaque copy sheet and this image is caused to penetrate or to be rendered visible through the copy sheet to give a right-way-round image on the top side of the sheet. The image, which is caused to penetrate or to be rendered visible may be either a latent or visible one the former being then developed on the top side of the sheet in the usual way, e.g. as described in Specification 943,401. If a porous copy sheet is used the image penetrates readily but in other sheet materials the latent image may be reinforced by treatment with a developing agent which may be a colourless powder, e.g. a wax such as glyceryl monostearate, which enables the image to penetrate the copy sheet in latent form when activated by heat. Alternatively, the oil used may include or entirely consist of a material capable of penetrating the copy sheet such as benzoic or pyrogallic acid. If a visible image is to penetrate the copy sheet the oil should generally include a dye or pigment and may also include a penetrant. If a dye is used the top surface of the copy sheet may be treated with a dye solvent which assists penetration by drawing the dye through the sheet. If the dye is water soluble the top surface may be treated with moisture or steam. On the other hand, the oil may include a constituent capable of reacting with a second substance to produce a visible image the top surface of the copy sheet being treated with this substance. In a further form of copying the latent image is treated with a developing agent which includes a transparent. izer such that the fixing of the image renders the copy sheet transparent over the required areas. The fixing is usually effected by heat but a solvent or vapour may be employed. After the latent image has been treated with a powdered developing agent an offset may be taken from the developed image to thus produce a further right-way-round copy. An opaque backing sheet or coating may be applied to a copy sheet in which the image is finally visible on both sides thus forming a sheet with a singlesided image.

Title: Rotary valves
IPC: B01D29/00
Filed: 1974-10-15
Abstract: 1489068 Valves WIX INTERNATIONAL CORP 15 Oct 1974 49280/76 Divided out of 1489067 Heading F2V A rotary valve comprises a cylindrical housing with two axially spaced outlet ports 122, 123, a single inlet port 124 located either opposite and intermediate of ports 122, 123, as shown in Fig. 8, or at one end of the housing (Fig. 16), and a valve sleeve 126 rotatable within the housing to connect port 124 alternately with ports 122, 123. Valve sleeve 126 has in its side wall four circumferentially spaced ports 136, which keep its interior permanently communicating with inlet port 124, a port 131 which extends 270 degrees round the sleeve, in line with outlet port 122, and a port 133 extending round 90 degrees, in line with outlet port 123. The axial centre lines of ports 131 and 133 are 180 degrees apart round the sleeve. The sleeve is keyed for rotation to a shaft S which extends out of the housing through end seals located in end caps 137, 138 clamped to the housing by tie rods 165. Retainers 157, 158 engage and urge seal members 156 axially inwards. In Fig. 16, ports 181, 182 are located in a common unit 180, bolted to a flat portion of housing 172 at 184, and communicate alternately with conduit 52<SP>1</SP> which opens into chamber 192 communicating with the interior of sleeve 126<SP>1</SP> via circumferentially spaced passages 191 in end cap 188 and similar passages (136<SP>1</SP>) in adjacent end wall (127<SP>1</SP>) of the sleeve. The shaft S is mounted in a blind bearing 193 at one end and extends from the housing at the other where it carries a gear 210 by which the sleeve is rotated. Fig. 20 (not shown) illustrates an alternative end seal for withstanding internal pressure. The valves are operated in pairs, either geared together side-by-side or linked by a common shaft S, and rotated at up to 600 r.p.m., to repeatedly draw liquid through a filter and reverse the flow to clean the filter. By virtue of the different angular dimensions of the sleeve ports the forward and reverse flow times differ and a net forward flow is achieved.

Title: Improvements in or relating to electric high voltage cables
IPC: H01B9/02
Filed: 1969-10-09
Abstract: 1,207,929. Improvements in or relating to high voltage cables. NEDERLANDSCHE KABELFABRIEKEN N.V. 9 Oct., 1969 [16 Oct., 1968], No. 49679/69. Heading H1A. A high voltage cable has one or more insulated conductors, and over the insulation is deposited a layer of material having a voltage dependent resistance characteristic, for example a lacquer containing silicon carbide, the whole being covered by a conducting sheath for electrostatic screening. When terminating the cable, to prevent excessive field concentrations at the surface of the insulation, it is only necessary to strip the sheath for a distance related to the voltage at which the cable will operate, and to make a simple connection to the voltage dependent resistance layers, whose characteristics ensure that voltage gradients large enough to cause surface discharges will not occur. The leakage path of the exposed layer can be increased by removing a part of it.
