Title: Improvements in/or relating to colour photography
IPC: G03C7/00
Filed: 1929-01-03
Abstract: 327,200. Chapman, W. Jan. 3, 1929. Drawings to Specification. Colour photography, multicolour screen processes.-In a process for printing from component colour-record negatives, a positive emulsion on a base bearing a regular pattern of colours is successively exposed to each negative, so that only the emulsion covering the colour on the base corresponding to the negative is exposed. In an example, the base is ruled with red, green and blue lines and a grating consisting of transparent lines and opaque lines double the width is laid over it. The green partial negative is printed with the transparent lines of the grating in register with the green lines on the base, and the remaining negatives are printed similarly, the grid being shifted between the printing. For kinematography, a film produced for example as described in Specifications 319,195 and 324,989, [both in Class 97 (i), Optical systems &c.], is projected on to a film bearing red-orange, and greenblue lines, two shutters co-operating with a grating having transparent and opaque lines of equal width being used.

Title: Improvements in or relating to housings for apparatus employed in submarine cable systems
IPC: H03G3/30
Filed: 1941-01-08
Abstract: 545,846. Cable joints. ELECTRICAL RESEARCH PRODUCTS, Inc. Jan. 8, 1941, No. 278. Convention date, Jan. 23, 1940. Addition to 479,170. [Class 38 (i)] In a housing for apparatus included in a submarine cable, the joint between the cable and the housing comprises a rigid insulating closure sealing the end of the housing to a central conductor, and a non-rigid insulating seal around the central conductor, the space between the two seals being filled with insulating liquid. The rigid seal 52 is of glass sealed directly to a metal ring 53 and to a metal bush 55, the ring being attached by solder 54 to a hollow plug 30 that closes the end of the housing of steel rings 21. The non-rigid seals 60 consist of rubber, vulcanized on to brass tubes 61, 81 and having a tapered end fitting into a hard rubber bushing 80. A support 70 screwed on to the tube 61 is gripped between abutment rings 74, 75 when the ring 81 is screwed into the plug 30 leaving spaces 32 that communicate through passages 72 and are filled with insulating liquid through filler tubes 85, 86. The space around the ring 81 is enclosed by a member 91 that supports a tube 90 around the splice 102 between the tube 61 and the conductor 100, and is filled with insulating liquid through a filler tube 94, the liquid also flowing into the tube 90 at the end of which it is confined by an elastic sleeve. After filling with liquid, the filler tubes 85, 86, 94 are cut off and bent down and embedded in solder 33 that seals the joint between the member 91 and the plug 30, and also holds in place an outer steel ring 31 within a pliable copper sheath 23 that covers the housing. A layer of copper 96 is applied by spraying or electro-deposition to cover the joints between the sheath 23 and the tube 90. A collapsable annular chamber 73 containing gas under pressure serves to control the pressure applied to the housing in the event of a fault developing in the seal. Rings 97 formed of wrappings of copper tape build up a tapered surface on which jute layers 112, 114 and armour wires 113 are laid to connect with those of the cables. U.S.A. Specification 1,942,260 is referred to.

The semi-ester may be derived from propanol, butanol, pentanol, hexanol or cyclohexanol, and specified salts are the alkali metal and ammonium salts. Specified catalysts are potassium, sodium and ammonium persulphates, perborates and hydrogen peroxide, and mixtures thereof with reducing agents, e.g. sodium pyrosulphite, sodium metabisulphite, sodium formaldehyde sulphoxylate and triethanolamine.  The medium may also contain buffers, e.g. primary and secondary potassium phosphates, and organic solvents, e.g. t.-butanol.

Abstract: 747,372. Dashpots. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. Jan. 12, 1954 [Jan. 12, 1953], No. 910/54. Class 108 (3). [Also in Group XXIX] To prevent overcontrol in a fluid-pressure power steering system for a vehicle (see Group XXIX), the servomotor is provided with a dashpot comprising a piston 166 carried by the servocylinder and working in a cylinder 162 carried by the servopiston. For slow movements of the servocylinder the liquid on one side of piston 166 can pass to the other side through passages 188 through the piston and a choke 192. For fast movements of the cylinder, a pressure difference is built up across the choke, and when this attains a sufficient value, the appropriate one of a pair of by-pass relief valves 206, 210 is opened to equalize the pressure. Each relief valve is relatively heavily spring-loaded and is carried by a lightlyloaded check valve 198 or 202. Thus, if pressure rises sufficiently to the left of piston 166, relief valve 206 and check valve 202 will be opened. To allow for the varying volumes of the chambers on the two sides of piston 166, liquid can flow into chamber 174 from an auxiliary chamber 176, flow taking place through a small passage 218 and, in one direction, also through a non-return valve 222.
