Title: Improvements in or relating to speed control means
IPC: F02D29/00
Filed: 1950-05-05
Abstract: 675,413. Speed governors. UNITED AIRCRAFT CORPORATION. May 5, 1950 [May 12, 1949], No. 11156/50. Class 57 [Also in Group XXIX] Speed control means comprises a speed governor, means for biassing the governor in response to the rate of change of the governed speed, means for creating a pressure differential varying with the governed speed, mechanism responsive to changes in the bressure differential for temporarily actuating the biassing means and means gradually bleeding the charge in pressure differential from the mechanism to eliminite the bias. The governor is used for controlling a variable pitch propeller 14 and comprises flyweights 36, driven from the propeller shaft 48, which actuate a pilot valve 26 controlling the flow of pressure fluid, supplied by a pump 16 through a pipe 56, pressure regulating valve 20 and a pipe 22, to either of pipes 28, 30 leading to a fluid motor in the propeller hub. An excess pressure relief valve 24 communicates with a fluid reservoir 18. The governor is loaded continuously by a spring 38 engaging an adjustable abutment 40 and is biassed temporarily, in response to an acceleration of the propeller, by a fluid operated piston 106 in a chamber 72. The biassing fluid is supplied by a pump 108 and is controlled by a piston valve 97, movable in a chamber 76, having lands 98, 100 cooperating with ports 102, 104 leading respectively to each side of the piston 106. The lands 98, 100 have "negative lap" so that when the valve 97 is central in its chamber under the action of opposed springs 90, 92 the fluid is relieved from both sides of the piston. A sleeve 120 in chamber 76 is rotated continuously to reduce friction and the opposite ends of the piston valve are connected by a bleed orifice 96. The piston valve 97 is actuated by a pressure differential acting across its ends and created by a venturi 50 supplied with pressure fluid by the pump 16 driven from shaft 48. The throat 52 of the venturi is connected by pipe 86 with the lower end of valve chamber 76 and the run 54 of the venturi by a pipe 78 with a second chamber 74 containing a spring loaded piston 82. Chambers 74 and 76 are in fluid communication at their upper ends through pipe 80. When the propeller accelerates, the pressure differential on the venturi increases, due to the increased output of the pump 16, and the valve 97 is moved to bias the governor. The pressure differential on the valve is gradually eliminated through the bleed orifice 96 and the valve is then centered thereby removing the bias.

Title: Improvements in or relating to reducing the sulfur content of coke containing a high percentage of sulfur
IPC: C10L9/02
Filed: 1955-04-18
Abstract: 768,909. Desulphurizing coke. ESSO RESEARCH & ENGINEERING CO. April 18,1955 [May 21, 1954], No. 11171/55. Classes 50 and 55 (1). In a process for reducing the sulphur content of coke, particularly petroleum coke, containing a high percentage of sulphur, the coke particles are first oxidized at a temperature between 600‹ and 1000‹ F., preferably 650-850‹ F., for from 15 minutes to 50 hours with a gas containing free oxygen obtaining as oxidized coke a minimum of 80 per cent by weight, preferably 90 per cent, of the original coke, the oxidized coke being then treated with hydrogen or a hydrogen-containing gas at a temperature between 1200‹ and 1700 F., preferably 1400- 1500‹ F., with a minimum flow of hydrogen or hydrogen-containing gas of 100 volumes of hydrogen per volume of coke per hour. Air or oxygen-enriched air may be employed for the oxidation or when the higher oxidation temperatures are used air may be diluted with steam, nitrogen or flue gas. The oxidation may be effected by treatment of a fired bed of the coke particles but is preferably effected with the coke particles as a fluidized bed. The hydrogen treatment may be carried out at pressures above atmospheric and last for between 10 minutes and 10 hours, it may be effected with the coke particles as a fired bed, a fired moving bed or a fluidized bed. The gas resulting from purification of the gas obtained by coking heavy oils or the tail gas from a hydroformer, may be employed as a hydrogen-containing gas for the hydrogen treatment. In the drawing, particulate coke particles from a fluidized coking zone pass by line 2 to a fluidized oxidation zone 1, air for the oxidation being admitted at 7. The temperature of the bed in the zone 1 is controlled by a cooling coil 6a, waste gases leave by line 5. Oxidized coke enters through a line 8 a hydrogen-treatment zone to where it is treated as a fired moving bed with a hydrogencontaining gas fed into the zone through line 9, desulphurized coke is withdrawn through line 11. The oxidized coke may be preheated in a heating zone 16 and the hydrogen-containing gas may be preheated in a heating zone 15. In an example coke containing 7 per cent sulphur had its sulphur content reduced to 1.7 per cent.

Chemical manufactures, furnaces for. - In a high-pressure furnace for conducting chemical reactions such as the synthesis of ammonia, combustion is effected in a chamber separate from the reaction chamber. and at a pressure approximately the same as that at which the reaction takes place. The apparatus shown comprises a strong steel shell A lined with non-conducting material B. Combustible gas and air are supplied to the chamber K through pipes H, N respectively, and the products escape through a coil L and a relief valve P loaded to blow off at the desired pressure. The nitrogen-hydrogen mixture is supplied by the pipes R, and is circulated by a pump E through the pipe F, over the coil L and combustion chamber K, through catalytic material C', and back to the pump. When the mixture is used as the combustible gas, a portion is supplied through the non-return valve G to the combustion chamber K. The ammonia produced is absorbed between the outlet D and the pump E. The combustion chamber may surround the reaction chamber, and the pressure in the latter may be utilized for controlling the valve P.

Title: Method for the partial or total hydrolysis of cellulosic material
IPC: C13K1/02
Filed: 1945-05-11
Abstract: Fermentable carbohydrates are obtained by subjecting cellulosic material in a moist state to a partial hydrolysis by means of hydrochloric acid of 37 to 50 per cent strength by weight in butyl alcohol, removing the solid residue and then subjecting this to at least one further hydrolysis.  In an example finely ground wood with a humidity of 5-8 per cent is suspended in normal butyl alcohol saturated with water, and hydrochloric acid gas passed in under pressure till a concentration of 45 per cent is reached. After digestion for a few hours the acid and alcohol are largely removed by evaporation under reduced pressure and then the resultant solid is again hydrolyzed with the residual acid together with water vapour under pressure.  The final product is separated by removing both the acid and liquids by evaporation.

[Class 112.] In a boot-sole sewing-machine employing a cross stitch, the necessity for vibrating the needle laterally is obviated by providing a double-ended curved needle, the machine being capable of sewing chain or lock stitches by replacing the double needle by a single one. The needle c has two curved hooks c<1>, c<2> oscillated by the needle holder a about the axis b and co-operating with the shuttle d and threaded looper i to form a cross stitch as shown in Figs. 6 and 7. The looper i presents the thread alternately to each of the hooks c<1>, c<2>. By replacing the double needle c<1>, c<2> by the single hook needle c<3>, Figs. 14 and 15, and using two threads e, j, the machine can be used to sew a lock stitch in the manner illustrated.
