Patent GB-853110-A (GB)
Title: Combustion system
Inventor: PROBERT RHYS PRICE
IPC: F01D9/02
Filed: 1956-03-26
Abstract: 853,110. Liquid fuel burners. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. March 20, 1957 [March 26, 1956], No. 9313/56. Class 75(1). [Also in Group XII] In a gas turbine, the liquid fuel is applied to the surface of a rotating disc from which it is thrown off centrifugally as a liquid sheet, into the high velocity air stream from the compressor. The fuel is thus atomised and mixed with the air in the flame tube. A secondary air stream from the compressor passes between the flame tube and the turbine outer casing and part mixes with the combustion gases in the turbine and part flows back towards the flame tube inlet by a passage in the flame tube inner wall which is cooled thereby. The fuel spraying disc is slightly coned inwardly to cause the fuel to adhere by centrifugal force. As shown, the turbine 10, 12 is supplied from the flame tube 31 which receives air from the compressor 6, 8 driven by 10, 12 through shaft 14. The fuel is led into 31 from hollow shaft 23 through ports 45, 47, to the downstream surface of the disc 24. The latter rotates with 14 and the ports are dimensioned so that the fuel is thrown from the disc periphery as a sheet into the airstream at 36. Turbulence is increased by the paddles 51. The air flow from 6, 8 is divided by the flame-tube outer wall 32 into two annular streams, one through duct 35 and the other into 31. The inlet to 31 is divided by fingers 36, which may be shaped to meter the air-flow. The outlet from 31 is a number of channels 56 formed by corrugations spaced apart circumferentially in 32 to provide alternating passages which discharge streams of hot gas and air. The inner wall 33 of 31 is cooled by air pumped by fan 61 from 56 through holes 62, into passage 60. Specifications 853,108 and 853,109 are referred to.

Abstract: 526,960. Textile lubricants. KILBURN, B. E. D. (National Oil Products Co.). March 24, 1939, No. 9359. [Class 91] [Also in Group IV] In the production of sulphonated fatty materials, a crude sulphonation mass comprising sulphonated animal, vegetable or marine oils, fats or fatty acids is dispersed in at least an equal volume of a substantially anhydrous organic solvent, the mass is then neutralized, the precipitated salts are removed, and finally the solvent and residual moisture are removed by distillation. The neutralization is effected by a concentrated aqueous solution of an alkali, or by a solution of alkali in an organic solvent preferably used in taking up the sulphonation mass. The solvent used may comprise an alcohol, ether, ketone, hydrocarbon or chlorinated hydrocarbon, the following being specified :-ethyl and isopropyl alcohols, ethylene dichloride, trichlorethylene, petroleum ether, acetone, methyl ethyl ketone and methyl isopropyl ketone. A large number of vegetable and animal oils and fats and marine oils is specified as suitable for the sulphonation. Examples are given of the sulphonation of olive oil, castor oil, sperm oil, olive oil and oleic acid. The products are substantially anhydrous and salt-free, and may be blended with vegetable, animal or mineral oils or waxes, or with other substances such as fatty alcohols and fatty esters, to produce compositions suitable for the treatment of textile materials, leather and paper. Examples of such compositions include (1) mixtures of sulphonated olive oil, raw olive oil and white mineral oil, or sulphonated teaseed oil, white mineral oil and sperm oil, or sulphonated sperm oil and white mineral oil, for softening and lubricating rayon, silk, wool and cotton yarns, (2) mixtures of sulphonated olive oil and raw olive oil, white mineral oil and raw sperm fatty alcohols, for soaking natural silk, or finishing fabrics, (3) sulphonated tallow mixed with paraffin wax or coconut oil, tallow and paraffin oil, for finishing fabrics, or (4) sulphonated sperm oil and paraffin oil for finishing fabrics.

Abstract: 535,645. Photographic copying apparatus. KODAK, Ltd. June 3, 1940, No. 9685. Convention date, Aug. 11, 1939. [Class 98 (i)] A photographic copying apparatus, more particularly for recording titles on kinematograph film, comprises an easel 14 for the copy secured to the end of a bed 11 on which runs a carriage 16 for supporting a camera 29, together with a supplementary lens 36 mounted on the carriage and adjusted by means controlled by the movement of the carriage to maintain the image in the camera in focus as the carriage is moved along the bed. As shown, the camera is held between angle-section clamps 28 on a platform 25 which is secured by bolts 26 to the carriage 16, tubular spacers 27 allowing the platform to be adjusted in height to suit different cameras. The carriage 16 is traversed by pinions on a shaft 17 which engage racks on the bed, and it is prevented from lifting by a spring-pressed ball 75 held in a well 78 carried at each corner of the carriage, the balls engaging the underside of flanges 76 on the bed. The supplementary lens 36 is carried by a holder 39 which extends upwardly from the front of the carriage. It comprises a positive front and a negative rear component, the latter being axially movable for focusing by means of a bifurcated member 44 secured to a shaft 42 and engaging pins 46 extending through slots in the lens mount from a sliding sleeve in which the negative component is carried. The member 44 is rocked to focus the lens by a lever 57, the upper end of which is held in contact with the member 44 by a spring 64 whilst its lower end bears on the edge of a cam disc 56 which is rotated through gears (not shown) from a worm 51 on the shaft 17 when the latter is rotated to traverse the camera. An arm 70 on the shaft 42 carries a spring plunger 71 which may be engaged in one of a number of holes in one side of the lens holder 39, so locking the shaft 42 and fixing the focus of the apparatus. Titles may thus be changed while the apparatus is out of focus, and by movement of the arm 70 titles may be " zoomed " into and out of focus.
