Title: Improvements in fuel supply systems
Inventor: CAREY FREDERICK HENRY
IPC: F02C7/22
Filed: 1947-07-09
Abstract: 654,248. Gas turbine plant. DOWTY EQUIPMENT, Ltd. July 9, 1947, No. 18182. [Class 110(iii)] In a fuel system for a continuous combustion gas turbine engine having a fuel pump driven independently of the engine communicating directly with the burners through a valve controlled passage, the valve closes the passage when the engine is at rest and opens the passage when the engine begins to rotate. The fuel system shown, Fig. 1, comprises a main engine driven variable delivery fuel supply pump 13. an engine driven fixed delivery circulating pump 12 and a low pressure booster pump 16 independently driven by an electric motor 17. The system also comprises a fuel tank 14, low and high pressure cocks 18 and 19, a throttle 15, an isolating valve 20, a trip valve 21, a circuit control valve 22 and various non-return valves. In the position shown, the system is at rest and the cocks 18 and 19 are shut off. The valve 18 shuts off the fuel supply from the booster pump 16 to the supply pump 13 and the supply to the circuit control valve 22. In this condition, the circulating pump 12 is still connected to the tank 14 through the pipes 26, 27, 28, 29. When it is desired to start, the motor 17 is energized. and the cock 18 opened. Fuel from the pump 16 is then allowed to pass to the inlet side of the pump 13 and along a pipe 34 as far as the isolating valve 20, The engine is then started by the starting motor and the high pressure cock 19 moved to the left. As soon as the engine rotates, the pumps 12 and 13 commence to deliver fuel and the delivery pressure from the pump 13 is transmitted through the lines 35 and 36 to the movable element of the isolating valve 20 which then moves against the action of the spring 30 to the right. This allows fuel to pass direct to the burners 11 from the pump 16 through the pipe 34, passage 37 and pipe 27 and from the supply pump 13 through the pipes 35, 36 and 38, passage 37 and pipe 27. At this stage, the pressure in the pipe 27 is insufficient to open the trip valve 21. When the speed of the unit is sufficient to make it self running, the pressure in the pipe 27 will have risen such as to open the valve 21 and cause fuel to act on the movable element of the circuit control valve 22 which moves to the left. This valve then cuts off the direct supply of fuel to the burners 11 by the pump 16 through the pipe 24, and allows the supply pump to supply fuel to the suction of the circulating pump 12 through the pipes 35, 39, 40, 41 and 42. The resulting increase in pressure in the pipe 27 acting on the movable element of the isolating valve 20 moves this element to the left and shuts off the fuel supply to the burners 11 from the pump 13 through the pipe 27. The system then runs normally with the pump 12 circulating fuel through the burners and the supply pump 13 being primed by the booster pump 16. Specification 654,244 is referred to.

Title: Process for regenerating chrom-oxyfluoride fluorination catalysts
IPC: C07C17/00
Filed: 1969-04-10
Abstract: 1,253,564. Regeneration of chrom-oxyfluoride catalysts. FARBWERKE HOECHST A.G. 10 April, 1969 [11 April, 1968], No. 18368/69. Heading B1E. [Also in Divisions C1 and C2] In a process for the fluorination of a chlorinated hydrocarbon or perchlorinated hydrocarbon, for example chloroform, hexachloroethane or carbon tetrachloride, with hydrogen fluoride in the presence of a chrom-oxyfluoride catalyst, the catalyst is regenerated, as required, by discontinuing the flow of chlorinated or perchlorinated hydrocarbon over the catalyst and passing hydrogen fluoride alone over the catalyst at a temperature of from 100 to 600C, for example at the temperature prevailing during fluorination of the chlorinated or perchlorinated hydrocarbon, and at a pressure preferably of from 1 to 10 atmospheres; during regeneration, which may be effected for a period of from 1 to 60 hours, the amount of hydrogen fluoride passed over the catalyst is at least 5 grams of hydrogen fluoride per litre of catalyst per hour. The chrom-oxyfluoride catalyst may be prepared either by fluorinating a hydrated oxide of trivalent chromium, for example hydrated chromic oxide (Guignet's green) or chromium- III-hydroxide, with hydrogen fluoride or by heating hydrated chromic trifluoride in a current of oxygen or nitrogen.

Abstract: 1,188,606. Reactive dyestuffs. FARBENFABRIKEN BAYER A.G. 18 April, 1968 [19 April, 1967], No. 18414/68. Heading C4P. The invention comprises reactive dyestuffs of the general formula wherein D is the radical of an organic non- anthraquinoid dyestuff, R is H or C 1 -C 4  alkyl or hydroxyalkyl, Q is alkylene, aralkylene, arylene, -CO- or -SO 2 -, n is 0 or 1, R 1  is an amino group which may be substituted, an optionally etherified hydroxy group or optionally etherified thio group or an optionally substituted hydrocarbon radical, and the group -(Q) n -N(R) is linked directly to a carbon atom of an aromatic carbocyclic ring in D. D may be of the mono-or dis-azo series which may be metallized, or the phthalocyanine, stilbene or nitro series. The dyestuffs may contain further fluorotriazinylamino groups and also one or more sulphonic acid groups. The dyestuffs are prepared by introducing into an organic non-anthraquinoid dyestuff or dyestuff intermediate, by known methods at least one group of the formula wherein R and R 1  are as defined above, and when an intermediate is used, converting this in known manner into the reactive dyestuff, e.g. by diazotisation and/or coupling, or condensation acylation, reduction, metallization or sulphonation reactions. The fluorotriazinyl group is preferably introduced by reacting a dyestuff or an intermediate containing a group -(Q) n -N(R)H with a compound wherein R 1  is as defined above and X is a radical which is split off as an anion under the reaction conditions. In a further method, dyestuffs containing a fluorotriazinylamino group having X as a substituent on the triazine ring may be reacted with ammonia or with amino, hydroxy or thio compounds to introduce the group R 1 . Many examples are given and the dyestuffs dye hydroxyl group containing textile materials e.g. natural and regenerated cellulose, and nitrogen containing textile materials e.g. wool, silk, synthetic polyamides and polyurethanes in all shades.
