Patent GB-897672-A (GB)
Title: Improvements relating to fuels for internal combustion piston engines and to the operation of such engines
IPC: F02B3/06
Filed: 1959-01-14
Abstract: A method of running-in an internal combustion piston engine comprises running the engine on a fuel composition consisting essentially of a liquid base fuel suitable for operating the internal combustion engine and having dissolved therein a minor proportion of an oil-soluble aluminium compound which can be converted to the oxide by heating.  It is believed that, under the conditions prevailing during the combustion of the fuel in the engine cylinders, the aluminium compound breaks down into a highly abrasive form of aluminium oxide. As a result of the presence of this aluminium oxide, the running-in is effected in a considerably shortened time.  The liquid fuel may be gasoline or diesel fuel while the aluminium compound may be an aluminium glycolate, e.g. one of the formula (C3H7O)2AlO(CH2)18OAl (C3H7O)2, or a polymeric organic aluminium compound of the general formula OnAlmXp, where X is an acylate group, m, n and p are integers, m is not less than 2, m/n is 0,75 to 2 and m/p is 0,5 to 3. In the examples, the fuel composition employed consists of a gasoline or diesel fuel containing a commercial polymeric organic aluminium compound believed to be a solution in isopropyl oleate of the substance (OAlOOCR1)3 where R is an oleyl radical. Specifications 806,113 and 825,878 are referred to.
Patent GB-710151-A (GB)
Title: Process for the manufacture of n-acylated amino aryl sulphonamides
IPC: C07C311/45
Filed: 1952-01-17
Abstract: N1 - acylated aminoarylsulphonamide free from N4-acylated and N1,N4-acylated derivatives is prepared by reacting in aqueous solution an aminoarylsulphonamide with a carboxylic acid anhydride while maintaining the reaction mixture alkaline.  The pH of the reaction mixture is preferably maintained between 9 and 14, e.g. between 11 and 14, and when the reaction is finished, the pH is reduced to precipitate unreacted aminoarylsulphonamide and then further reduced to precipitate the N1-acylated aminoarylsulphonamide. Examples are given of the preparation of N1-acetylsulphanilamide by the action of acetic anhydride on sulphanilamide in the presence of aqueous caustic soda.  Specification 642,013 is referred to.
Patent GB-397188-A (GB)
Title: An improved method of producing multi-colour photographic images and kinematograph films
IPC: G03C7/28
Filed: 1931-11-16
Abstract: 397,188. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. Nov. 16, 1931, No. 1411/33. Divided on 397,159. [Class 98 (ii).] Multicolour photographic images and kinematograpbic films are obtained by causing oxidizing agents to act simultaneously on a plurality of coloured layers which contain metal deposit part images. Thus, three differently coloured and sensitized silver halide emulsions are formed one on another ; the lowermost contains a blue dyestuff and is sensitive to red, the middle layer contains a red dyestuff and is sensitive to green, and the uppermost contains a yellow dyestuff. After exposure or copying, the layers are developed, fixed and treated in a bath comprising (1) sodium chlorate, hydrochloric acid and water, or (2) potassium bromate, sulphuric acid, copper sulphate, potassium iodide and water. When the desired colouration is obtained the image is further fixed in sodium thiosulphate. Reversed dye images are obtained. The reaction may be accelerated by adding catalytically-acting salts, e.g. of vanadium, uranium, molybdenum or iron. Mixed tones may be obtained by employing a mixture of dyes of varying bleaching rapidity. Films may be sensitized on both sides, e.g. containing on one side a red-coloured, red-sensitive layer, and on the other a greensensitive, blue-green layer. The dye may be applied after coating. Substantive or acid dyes are particularly suitable. Instead of silver deposit images another metal such as mercury may be used. Specifications 249,530, [Class 98 (ii), Photographic processes &c.], and 397,159 are referred to.

Title: Flame monitors
IPC: F23N5/12
Filed: 1976-01-15
Abstract: 1497503 Burner control LGZ LANDIS & GYR ZUR AG 15 Jan 1976 [22 Jan 1975] 01631/76 Heading F4T  During positive half-cycles of the A.C. supply at terminal R, the operating winding FR of an electromagnetic relay is by-passed by a first diode D1 in series with a Zener diode Z, whereby the sum of the forward volt drops of these diodes is applied across the winding, i.e. about 1À4 volts. For negative half-cycles at supply terminal R current flows through resistor R2 and through the winding FR or the transistor T1 When transistor T1 is conductive the relay is de-energized and when transistor T1 is blocked the relay is energized although it is supplied only during the negative half-cycles at terminal R. A capacitor C is charged via a second diode D2 during negative half-cycles at the supply terminal R and current flow from point b through resistor R5 enables transistor T1 via transistor T2 causing de-energization of the relay. However if a flame is present, ionization current flows through the resistor R8 due to the rectifying action of the flame. This current exceeds that through the diode D2 for a normal flame at the burner B so the transistors T1, T2 are blocked and the relay is energized.

Title: Improvements in or relating to electron discharge devices
Inventor: TURK WALTER ERNEST
IPC: H01J40/06
Filed: 1947-01-22
Abstract: 657,534. Cathode materials and processing. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 22, 1947, No. 1961. [Class 39 (i)] An electron discharge device has a photoelectron or secondary-electron emitting electrode made by evaporating a substance on to a supporting surface and simultaneously on to a further surface, exposing the substance deposited on said supporting surface to a sensitizing substance and thereafter evaporating the substance deposited on said further surface on to said supporting surface. In order to form a photo-cathode on the inner surface of an envelope a pellet of silver or antimony is supported by a tungsten heating coil and a surface for intercepting some of the evaporated metal is provided by an additional tungsten heating coil the wire of which projects from both ends of the coil in an axial direction and is passed through loops formed at the extremity of supporting wires which serve as current conductors for the coil, one of the projecting ends of the wire being fitted with a pair of radial arms carrying small pieces of magnetic material at their ends so that the coil can be turned about its axis by the manipulation of a magnet outside the envelope. Oxygen is introduced into the envelope to oxidize the metal deposited on the envelope and on the additional coil followed by the introduction of caesium vapour and baking of the envelope to cause the caesium to sensitize the metal deposited on the envelope, deposition of the caesium on the additional coil being prevented by passing current through it to heat it. The additional coil is then turned to face the relevant part of the surface of the envelope and a current is passed through it sufficient to evaporate the metal deposited on it and cause it to be deposited on the envelope. The additional coil may be replaced by a small metal plate which may be heated by establishing a high-frequency field. The intercepting member may be moved to another position in the envelope or removed from the envelope after the evaporation of metal therefrom, for example by the manipulation of a magnet outside the envelope where the intercepting member comprises magnetic material. More than one intercepting member is provided when more than two successive depositions of metal are required. Specification 639,995 is referred to.

Title: Improvements in the extrusion of rubber compounds
Inventor: RICHARDS ARTHUR BRUCE FRASER G
IPC: B29C48/395
Filed: 1955-01-24
Abstract: A vulcanizable rubber compound is prepared in two batches, each batch containing a vulcanizing agent which works in conjunction with a vulcanizing agent in the other batch to bring about vulcanization of the compound: for example, one batch may contain sulphur and the other may contain accelerator.  Each batch is prepared in elongated form and both are fed simultaneously to an extruder where they are mixed and extruded in the required shape. Each batch may contain more than one agent.  From the extruder the shaped compound may pass through a tube containing steam where it is vulcanized.  The invention obviates premature vulcanization during preparation and handling of the compound before it is fed to the extruder, since, for example, each batch may be premixed and stored for extrusion when required.  Each batch may contain half of the rubber and half of all the other ingredients except the vulcanizing agents, the batches being formed in strips and equal numbers thereof fed to the extruder. Or one strip may contain only a small part of the rubber and all of the sulphur or accelerator(s), in which case it is of smaller cross-section than the others and may be fed sandwiched between two others or in a groove or grooves in a single strip.  Strips may be fed twisted together by means of rollers.  The invention may be applied to the insulation and/or sheathing of electric cables. Specification 736,022 is referred to.
