Title: Improvements in or relating to the production of valuable organic compounds from carbonaceous materials by treatment with hydrogenating gases
IPC: C10G1/06
Filed: 1937-01-06
Abstract: Extracts obtained by extracting coals &c. with solvents are purified from sulphur prior to their treatment with hydrogenating gases by treatment with alkali solution at a temperature below the boiling point of water under the prevailing pressure.  The coal extracts may be prepared by heating coal with hydrocarbon solvents, e.g. tetrahydronaphthalene, decahydronaphthalene, pyridine, quinoline, phenols, anthracene oil fractions and particularly solvents boiling above 250-350 DEG  C. the extraction being carried out at increasing temperatures near to but below the decomposition temperature of the coal and under pressure, e.g. of the solvent used or of gases, e.g. hydrogen.  The alkali solutions employed comprise caustic soda, caustic potash or ammonia in alcoholic or aqueous solution and may be used in concentration of 5-50 per cent, the treatment being carried out at from room temperatures to 150 DEG  C. or higher and under increased pressure up to 100 atmos. or more the pressure being sufficient to prevent formation of steam.  The alkali solution and the carbonaceous material may be flowed through vessels in countercurrent or mixed in a vessel through which an inert gas is bubbled.  Catalysts, e.g. lead sulphide, cadmium sulphide, zinc sulphide, clay, barium sulphate or elementary sulphur may be present. The alkali may be sprayed into the vaporized material and multi - stage treatment may be employed.  After the alkali treatment further removal of sulphur may be obtained by heating the material with oxides of copper, iron, lead, manganese, zinc or antimony on carriers.  The hydrogenation treatment is preferably carried out in presence of a nickel catalyst at temperatures of 200-400 DEG  C. and under pressures of 10-50 atmos. the quantity of nickel employed being from twice to eight times the equivalent of the remaining sulphur. The nickel catalyst is preferably prepared by reducing nickel oxide or nickel formate to nickel under the hydrogenating conditions, the finely divided nickel being supported on carriers, e.g. silica gel, alumina, charcoal or larger fragments of nickel may be placed in a perforated cage.  The hydrogenation treatment may be repeated, tungsten or molybdenum catalysts being used instead of nickel.  The spent nickel catalyst may be regenerated by heating with air or oxygen or treatment with nitric or organic acids.  Bituminous coal is extracted at 250-350 DEG  C. with decahydronaphthalene or a mixture of hydrogenated naphthalenes containing 10 per cent pyridine.  The extract is flowed through a series of towers in countercurrent to a 20 per cent caustic soda solution.  The extract is washed and treated at 80 DEG  C. with freshly precipitated copper oxide or iron oxide and is then heated to 350 DEG  C. with hydrogen under 100 atmos. pressure while flowing through a series of cages containing reduced nickel oxide.

Title: Thrust compensator for a group of jet lift engines for an aircraft
Inventor: BISHOP GEOFFREY STANLEY
IPC: B64C29/00
Filed: 1963-01-04
Abstract: 1,039,531. Jet propulsion plant. ELLIOT BROS (LONDON) LTD. Jan. 1, 1964 [Jan. 4, 1963], No. 533/63. Heading F1J. [Also in Division B7] In an arrangement for maintaining a predetermined total lift thrust for an aircraft, each engine of a group of three jet lift engines arranged in a wing pod has means, such as a pitot tube, a static tapping or a pair of venturis, in the jet pipe for forming a pressure source representative of the pressure therein. Each pressure source is connected with a double-acting cylinder 75, 76 or 77 through a pair of conduits and a valve 88, 89 or 90, which valve, in the event of fracture of one of conduits, seals the fractured conduit. A common chamber. 79 having a controlled leak device 103 is connected to the piston rod end of each cylinder 75, 76, 77 through conduits 97, 99, 101 and non-return valves 98, 100, 102, and with the other end of each cylinder through conduits 113, 114, 115. Due to the non-return valves, the fluid in the chamber 79 assumes the pressure of the highest representative pressure. One or more cylinders 78 connected, through a valve 91 and a pair of conduits, with a representative pressure source of one or more lift-forward thrust engines may be provided. The four piston rods 106 to 109 are fixed to a member 110 carrying a throttle control rod 112 connected to each of the three lift engines and the pilot's primary throttle control. During normal operation the pressure differential across the four pistons in the cylinders 75 to 78 is balanced by the action of a spring 111 so that the pistons assume the positions shown. However, in the event of reduced power of one of the engines, the pistons and the rod 112 move to the right resulting in opening of the throttles of the three lift engines and production of makeup thrust. The diameter of the cylinder 78 is less than that of each of the cylinders 75, 76, 77 so that failure of the lift-forward thrust engine produces a smaller make-up thrust than that caused by failure of one of the main lift engines. In an alternative embodiment, Fig. 1 (not shown), the four cylinders and the common chamber are formed in a single housing with the ends of the cylinders opening into the chamber. Further, a single conduit connects each representative pressure source with the respective cylinder, and has a branch which connects with the common chamber. In modifications of these embodiments the balancing spring may be replaced by a pneumatic system or a mechanism equivalent to a zero rate spring, or a balancing spring may be associated with each cylinder, the piston rods being interconnected through a series of pivoted linkages arranged to move the throttle control rod an amount representative of the algebraic sum of the individual movements of the piston rods.

Abstract: 444,044. Knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.- (Assignees of Lawson, R. H. ; 55, Cooke Street, and Smith, W. L. ; 51, Roberts Street, both in Pawtucket, Rhode Island, U.S.A.) Jan. 9, 1935, No. 789. Convention date, Jan. 10, 1934. [Class 74 (ii)] The butts of jacks &c. 62 which affect the character of the stitches are acted upon by a plurality of elements such as plungers or strips 33 which when in one position select the jacks and therefore the needles and when in the other position fail to select the jacks &c., each of the elements 33 being independent of the others, and movable from one position to the other by hand. In the machines shown, a number of plates 7 are spaced around the needle cylinder. Each plate carries jack cams 13, 14, 16 and a pillar 9 carrying the needle cams 68, 69, 70. Each plate 7 also carries a vertical bank of the selecting striplike elements 33 sliding in notches in pillars 23, 24, 25, 26 and separated by other fixed strips 27. The strips 33 are pulled towards the needle cylinder by springs 34, 35 to an extent determined by the adjustable plate 43, but can be pulled out separately by hand and there held by the shoulder 40 engaging the post 24. In the machine shown in Figs. 4, 6, 10, 11, the elements 33 are horizontal and above the bank of elements 33 is a cam 59 adjustable by means of a cam lever 53 and then fixed by screws 52. The jacks 62 have bits 71 at various heights to engage the cam ends of the strips 33. After, say, plain knitting at position A the selected jacks 62 are pressed inwards by the corresponding strips 33, hook on to their needles 65 and are lifted slightly by the cam face 76. The other jacks are not pressed inwards by the cam 59 until the corresponding needles have been lifted clear of them by the cam face 76. All the jacks are lowered by the cam 13 along with the selected needles, the butts of the selected needles taking a path 78 below the cam 68 while the butts of the unselected needles take a path above the cam 68. In the machine shown in Figs. 16, 20, 23 the needles and jacks have no hook engagement and the cam 59 is not used, but the strips 33<1> are inclined and themselves slightly lift selected jacks and needles, the lifting being completed by a cam 92. The butts of selected needles follow the path 93 and the remainder the path 94. The upper face 92<1> of the cam 92 is hollowed as shown in Fig. 23, and the cam is mounted on a pivoted plate 101 which will move against the action of a spring 104 should the cam foul a jack butt. The leading corner of the cam is rounded off.
