IPC: C10L1/196
Filed: 1958-07-18
Abstract: Oil-soluble copolymers derived from maleic anhydride, an alkyl ester of an alpha-beta unsaturated dicarboxylic acid, and a copolymerizable alkylene ester of a C1-C6 monocarboxylic acid are obtained by copolymerizing at a temperature above 70 DEG C. in the presence of a free radical catalyst which decomposes at a temperature above 70 DEG C.  The preferred alpha-beta-unsaturated dicarboxylic acid is fumaric acid although maleic or itaconic acids may be used.  The alkylene ester is preferably vinyl acetate but allyl derivatives may be used. The catalyst may be tertiary butyl perbenzoate, tertiary butyl hydroperoxide, 2, 2 bis (ter-butyl-peroxy butane), di-tertiary-butyl peroxide or di-cumyl peroxide.  The catalyst may be used in the form of an oil solution or slurry, and the reaction is preferably carried out under nitrogen.  The reaction is carried out for a period of time to copolymerize the reactants but not for long enough to form an insoluble gel.  The product may be added to hydrocarbon fuel or lubricating oils.  In an example, 4% of maleic anhydride, 2% of lauryl alcohol (as reaction modifier) 18,8% of vinyl acetate and 75,2% of lauryl fumarate were copolymerized, either at 60 DEG C. using 1% benzoyl peroxide as catalyst or at 95 DEG C. using 0,4% tertiary butyl perbenzoate.  Specification 807,737 is referred to.ALSO:Oil-soluble copolymers derived from maleic anhydride, an alkyl ester of an alpha-beta unsaturated dicarboxylic acid, and a copolymerizable alkylene ester of a C1-C6 monocarboxylic acid obtained by copolymerizing at a temperature above 70 DEG C. in the presence of a free radical catalyst which decomposes at a temperature above 70 DEG C.

Abstract: 600,492. Filtering liquids. AMES CROSTA MILLS & CO., Ltd., and BOLTON, J. F. Sept. 10, 1945, No. 23221. [Class 46] In a filtering means for fluids, such as sewage comprising a single filter bed and moving sprinkler means for distributing fluid over it, the sprinkler means is constructed so that one part distributes to one area of the filter bed and another part distributes to another. Means are also provided for supplying fluid selectively to either part of the distributor and for collecting fluid from the floor of the bed and delivering it as secondary fluid to the other part of the distributor to enable the system of alternating series filtration to be employed with a single filter bed. The filter bed shown in Fig. 1, is circular and is divided by a ridge c into two equal concentric areas c<SP>1</SP> and c<SP>2</SP> from the sloping floors of which the fluid drains to collecting channels a<SP>2</SP>, b<SP>2</SP> and passes along pipes q<SP>1</SP>, p<SP>1</SP> to humus tanks q, p, Fig. 6. The sprinkler has two pairs of rotating arms e, d supported on a hollow pillar f. The fluid is passed up the pillar into one or other of two annular troughs each of which feeds a pair of arms e or d and one of the areas c<SP>2</SP> or c<SP>1</SP>. Adjustable valves r and u, Fig. 6, are set so that the incoming fluid is passed to the longer pair of sprinkling arms d and collected from the outer filter arms c<SP>1</SP>. The fluid then passes through the tank q to the valve u whence it is returned by a pump t to the shorter pair of sprinkler arms e, collected from the inner filter area c<SP>2</SP> and discharged through the tank p and the valve u. By reversing the valves the fluid passes first through the inner and then through the outer filtering area.

Title: Improvements in or relating to operating systems for aircraft under-carriages
IPC: B64C25/22
Filed: 1947-08-22
Abstract: 638,887. Fluid-actuated valves. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Aug. 22, 1947, No. 23256. [Class 135] [Also in Group XXXIII] A fluid pressure control valve unit comprises a chamber 3 connected to a source of fluid pressure, a chamber 3a connected to fluid - pressure operated mechanism, a spring- loaded plunger 16 in the pressure chamber, coaxial inlet and outlet valves 9, 10 on a common stem 11 and a tubular seating element 12 for the inlet valve coupled to the plunger 16 so that when the pressure in the chamber 3 exceeds a predetermined value the seating element 12 is lifted to close the inlet valve and open the exhaust valve. The chamber 3a is connected to the fluidpressure operated mechanism by a passage 5 and to exhaust by passages 7, 8 whilst the chamber 3 is connected to the pressure source by a passage 4 leading into a through passage 6. The seating element 12 has a lip 14 and is supported by a ported flanged member 15 screwed to the plunger 16. A spring 19 normally maintains the exhaust valve 10 on its seating 13. The plunger 16 has a perforated rib 17 to facilitate access of fluid to its base, and a cylindrical extension 20 which houses a flanged guide 21, a guide tube 24 and a spring 22 adjusted by a screw 25 in a cover 26. Fig. 2 shows at 42 the control valve of Fig. 1 applied to a fluid-pressure system including a doubleacting jack 30 for operating an aircraft undercarriage 32 held in the retracted position by a catch 46 released by a piston and cylinder device 47. Normally the undercarriage is operated through the transmissions lines 34, 40 or 33, 39 selectively connected to a source of fluid pressure at 41 by a valve 48 controlled by the pilot. If this main operating system fails, the pilot opens a valve 44 to bring in an emergency supply which is connected to the pipes 39, 40 through shuttle valves 37, 38. pipes 35, 36 and 43, and the valve 42 which has an exhaust connection 45 corresponding to the passage 8 and a pipe connection 36 corresponding to the passage 5. Thus, pressure is applied immediately to the lowering end of the jack and to release the catch 46, but the exhaust through pipes 40, 36 is gradual as the valve 10 is not opened until a predetermined pressure has built up in the chamber 3. The Provisional Specification describes a modification in which both the seat and the valve member of the exhaust valve are movable, the valve member thereof being connected to a piston through a lever.

Title: Improvements in and relating to reaction vessels and their operation
Inventor: REYNOLDS PETER WILLIAM
IPC: B01J8/02
Filed: 1950-09-22
Abstract: <PICT:0702907/III/1> A converter for gas or vapour phase reactions over a solid catalyst in the presence of a liquid which is to be kept substantially out of contact with the catalyst, is provided with one or more columns packed with an inert material which surround and/or are surrounded by the catalyst material and are separated from the catalyst by pervious septa.  Liquid is introduced at the top of the column and gaseous or vaporous reactants are contacted with the liquid in the column and the adjacent catalyst, in cocurrent or countercurrent, the liquid loading being such that "break through" of the liquid to the catalyst does not occur. In Fig. 1, a column 8 of inert material such as silica chips, alumina pellets or mullite spheres, is surrounded by catalyst 6 such as tungstic oxide pellets. Liquid entering at 2 is distributed over the column and leaves at 2a; gas enters at 3, leaves at 4.  The pervious septum 5 may be gauze of glass wool or metal, particularly stainless steel such as "Staybrite" (Registered Trade Mark) or copper, perforated metallic or non-metallic sheets, or the inert material 8 may be superficially sintered to render it suitably pervious.  Two adjacent septa may be employed.  The converter is suitable for the hydration of propylene to isopropanol or the hydrogenation of olefines such as liquid di-isobutene to isooctane.  An example relates to hydrogenating isooctene which is fed to the upper surface of a column of silica chips in the centre of a reaction vessel, the column being surrounded by foraminate nickel/aluminium catalyst with an interposed copper gauze septum.  Hydrogen is passed downwardly through the catalyst and the temperature is maintained at 30 DEG C.  40 per cent. of the isooctene is converted to isooctane.  Specification 680,865 is referred to.

Title: Improvements in or relating to indoor fountains
IPC: B05B17/08
Filed: 1938-08-08
Abstract: 508,820. Fountains ; electric switches. GETTWART, K., and SCHMIDT, H. Aug. 8, 1938, Nos. 23339 and 23340. Convention dates, Aug. 31, 1937, and June 20, 1938. [Class 69 (i)] [Also in Group XXXVII] A self-contained fountain for standing or floating in a basin of water comprises a casing 1, 2, entirely closed except for the water inlet 6 and outlet to the jet nozzle 44, and containing a diaphragm pump 9, a motor 31 for driving it, dry batteries 27 supplying the motor, a gravity-operated switch 34 controlling the motor circuit, and an air chamber 26 for rendering the jet continuous. The use of a gravity switch, operated merely by tilting the whole device, and of a glandless diaphragm pump, avoids the possibility of leakage into the casing either through an aperture in it for a switch-operating member or from the pump. In the construction shown, the parts 1, 2 of the casing are separable, the joint being rendered water-tight by a sealing ring 3. The rubber or like diaphragm 10 of the pump is held by a cover 11 on the pump casing 9, which is integral with the lower part 1 of the casing. The pump draws water through the inlet 6 and delivers it through a passage 19 and connection 23 to the air chamber 26, whence it passes out through the jet nozzle 44, the inlet and outlet valves 17, 22 consisting of rubber flaps. The down strokes of the diaphragm are effected by a piston-plate 13 which bears on it and is carried by a rod 12 driven from a crank disc through reduction gearing 32 by a motor 31, the return strokes being made by a spring 15. Alternatively, the return as well as the down strokes may be effected by the motor. The cells 27 supplying the current are held by spring contact members 28. The gravityoperated switch shown in Fig. 4 comprises a tube 34 pivoted at 35 and containing a ball 40 which runs from one end of it to the other when the apparatus is tipped and retains it either in the open position shown or tilted in the opposite direction, when a ring 38 on it contacts with a spring 37 and makes the circuit. A buffer spring 41 limits the movement of the tube in the opposite direction of tilt. Another form of fountain differing in constructional details is described. In this construction, the switch comprises a pivoted member of U-form in cross-section, on which runs a ball, and which carries adjacent the pivoted point a laterallyextending tongue which in one direction of tilt engages a contact pin.
