Patent GB-413095-A (GB)
Title: Production and reproduction of pictures or designs by means of visible or invisible rays
IPC: D05C9/14
Filed: 1933-04-26
Abstract: 413,095. Photographic sensitive materials. KLEINER, S., 87, Rue Compans, Paris. April 26, 1933, No. 12192. Convention date, April 26, 1932. [Class 98 (ii).] Pictures or designs are formed by subjecting to the action of visible or invisible rays from an object or original, a cellulose product the permeability of which to fluids is changed by the action of the rays, and treating the exposed layer with a fluid. The cellulose layer may contain small quantities of non-volatile solvents, plasticizers, natural or artificial resins, copying inks, dyes or mineral salts and may be transparent or natural-coloured. Ultraviolet rays may be used for the exposure, and the time of exposure may be reduced by the use of intensifying screens such as are used in X-ray work, e.g., consisting of calcium or cadmium tunsgtate, and of additions to the layer of substances having an acelerating action such as tricresyl phosphate, triphenyl phosphate or titanium dioxide. The process may be used for the preparation of photographic positives or negatives, silent or sound films, patterned papers such as wall-papers or patterned dress materials, such as artificial silk. By applying a cellulose layer to the surface of other materials such as stone, glass, metal or leather, pictures or designs may be produced thereon.

Title: Improvements in the production of dicarboxylic acid derivatives
IPC: C07C61/16
Filed: 1958-04-17
Abstract: Cyclododecatriene-(1.5.9.) is reacted at elevated temperature with an unsaturated dicarboxylic acid anhydride or di-ester whereby addition of the cyclododecatriene molecule takes place at the carbon-to-carbon unsaturated bond of the acid anhydride or di-ester.  The reaction may be carried out at temperatures up to 400 DEG  C. preferably between 200 and 250 DEG  C.  A diluent such as toluene, xylene or trichlorobenzene may be present.  The molar ratio of cyclododecatriene to the unsaturated anhydride or ester may be between 1:5 and 5:1.  In general only 1 mol of the anhydride or ester is combined with each mol of the olefine. Compounds containing 2 mols of the anhydride or ester to each mol of olefine are formed only in minor amounts.  Examples describe the production of cyclododeca-trienylsuccinic anhydride and the corresponding di-n-butyl succinate compound by reacting cyclododecatriene (1.5.9.) with maleic anhydride, or with the di-n-butyl ester of fumaric or maleic acid.  Thionine, methylene blue, tert. butyl catechol, or phenothiazine may be present as polymerization inhibitors.

Abstract: 310,048. British Thomson-Houston Co., Ltd., (Assignees of Hull, J. I.). April 20, 1928, [Convention date]. Alternating-current commutator machines.-In an alternating-current motor of the commutator type in which the stator 10 is connected to the rotor 17 through a step-down transformer 13, 14 of relatively small rating in order that a lowvoltage rotor winding may be' used, the motor is cut out if it is stalled by means dependent on the resulting saturation of the transformer and the change in its transformation ratio. As shown, a tripping magnet 19 for the circuit-breaker 12 is energized by differentially-connected current transformers 20, 21 in the primary and secondary of the transformer 13, 14. The current transformers are so chosen that normally they balance one another. When the motor stalls (even although the current taken is not adequate to operate the usual overload trip 18) the balance is upset and the trip 19 brings out the circuitbreaker.

Title: Improvements in or relating to the production of emulsions
IPC: C09K23/00
Filed: 1926-05-13
Abstract: 280,096. Whatmough, W. A. May 13, 1926. Emulsions, making; medicines for internal use; ointments or salves.-An emulsion is produced by adding a protein solution with which a small quantity of alkali has been mixed to a fatty oil &c. to which a small quantity of a fatty acid, with or without a small quantity of alkali, has been added and mixing the whole. The emulsion may be thinned by the addition of water or an aqueous solution of an essential mineral salt such as iron citrate or sodium phosphate or fruit juices or syrups or both may be added to it. The quantity of alkali added is the amount requisite to make the electrolytic activity of the electrolyte or electrolytes in the aqueous phase such that the interfacial tension between the oil and water phases is sufficiently reduced to permit rapid or almost spontaneous emulsification. In one example an ounce of bran extract is well mixed with a sixtieth part of an ounce of a normal solution of sodium hydroxide; ten minims of a fatty acid and then twenty minims of the sodium hydroxide solution are added to two ounces of codliver or olive oil, and the two solutions are well mixed to produce a cream which may be used as a vitamin active food or medicine. One ounce of orange juice, or glycerine, honey, or a saccharine solution or mixtures thereof may be added. A preparation for toilet use may be made in the same way, a 20 per cent solution or mixture of neutralized casein in water replacing the bran extract and lard, lanoline, almond oil, olive oil &c. being used as the oil or fat. A further quantity of fatty acid, such as oleic acid, may be added to the emulsion and for hardening purposes paraffin wax may be added or paraffin molle replace part of the oil or fat. Finally the mixture is heated in a vacuum apparatus to about 140 F. to remove air bubbles and surplus water. To obtain a transparent emulsion an ounce of egg yolk is added to 30 minims of the sodium hydroxide solution; 10 minims of fatty acid are mixed with one ounce of castor oil, and the whole is thoroughly mixed. After adding to the emulsion so formed an ounce of glucose syrup, the product is evaporated under a vacuum until it is clear. Mention is made of oleic or stearic acid as fatty acids, of sodium carbonate or borax as alkalis and of gelatin as a protein. When casein or gelatine are used, the fermentation acids in them are neutralized by alkali to bring them to the approximate iso-electric condition before mixing with them the small quantity of alkali beforementioned.

Abstract: 252,189. British Thomson-Houston Co., Ltd., (Assignees of Hamilton, Tl%. S. H.). May r6, 1925, [6o?tvention date]. Regenerative systems for traction or other purposes. The driving motors M<1>, M<2>, Fig. 1, in regenerative braking, are excited by separate machines E<1>, E<2> having a common series fieldwinding F<4> and a common shunt field-winding F<3>. The exciter shunt field is automatically varied in strength by 'a rheostat 18, Fig. 3. driven by a reversible motor 19. During the first period of regenerative braking prior to the .exclusion of the starting resistances, the rheostat motor is under the control of a relay 24 responsive to the regenerated voltage, which ia thus maintained at a constant predetermined value. For the second period of regeneration with exclusion of the resist. a.nces a switch 4 is caused to by-pass the relay 24 and put the motor 19 under the, control of a relay 25 responsive to the strength of regenerated current, which is thus definitely limited. A greater strength can be obtained by manipulation of the controller so as to oppose the relay winding 25 by a winding 26 energized from the supply mains, or alternatively a lower limit of strength may be set by connecting the winding 26 so as to assist the winding 25. A selective controller S.C. is arranged to give series or parallel braking at will. The system comprises carn-operated and interlocked contactors for starting and accelerating the motors, and is described in detail in the Specification.
