Title: Process for the recovery of pale fatty acids from cottonseed black grease
IPC: C11C1/10
Filed: 1931-10-28
Abstract: Pale fatty acids are obtained by distillation from cottonseed, black grease, and other acid oils obtained from vegetable or animal oils by first oxidizing by air the volatile constituents liable to cause discoloration of the fatty acids so that lower boiling substances are produced, and separating these products from the acids.  The air may be passed through the acid oil or through the vapours from the still. Catalysts, e.g. ferrous salts, may be present.  The acid oil may first be distilled or be extracted with benzene or other solvent of the fatty acids.  The use of alkali chlorates, or bichromate and acid, in place of air is referred to.  In examples: (1) Air is bubbled through black grease at 90 DEG  C. for two hours in presence of 10 per cent by volume of 5 per cent ferrous sulphate; the fatty acids are separated from the aqueous layer, and distilled at 170-280 DEG  C. under reduced pressure, e.g. 15mm., and with or without steam. (2) Black grease is distilled while 15 vols. of air are drawn into the still by the vacuum pump; the vapours are fractionally condensed or are scrubbed, e.g. by heated fatty acids, mixed or not with triglycerides, to separate first the objectionable constituents. (3) A distillation residue from soya bean soapstock is saponified and acidified, and the crude fatty acids distilled; the distillate is blown with air for one hour at 90 DEG  C. and distilled. Specifications 19477/06, 121,777, 235,792, and 277,085, [all in Class 91, Oils &c.], are referred to.  According to the Provisional Specification the oxidation may be effected by any suitable oxidizing agent, e.g. air, alkali chlorate, or acidified bichromate.

Title: System for starting and stopping the flow of liquids or gases under pressure
IPC: F15B21/00
Filed: 1921-11-10
Abstract: 171,992. Faure, J. M. A. Nov. 23, 1920, [Convention date]. Pottery, throwing and turning. - Instantaneous starting or stopping of the flow of a fluid is effected by a rapid change in the direction of flow in a feeding pipe. The method may be applied to contro! the water supply to a disc of ceramic paste for the manufacture of a plate, so as to be synchronous with the working of the tool. In the apparatus shown, fluid flows from a pressure storage tank f through a pipe into a compartment c<1> of a cylinder divided into two compartments by a piston b, and further flows from this compartment through a pipe g<3> into the second compartment c<2> and an outlet pipe g<2> having a smaller resistance than the pipe g<3>. The piston being moved in one direc. tion or the other by a cam d and spring e, the consequent change of volume of the compartment c<2> induces a vacuum or plenum in the outlet pipe by reason of its lesser resistance, the flow being completely cut off when the piston closes the inlet port i of the cylinder.

Abstract: 793,615. Cone disc brakes. GENERAL MOTORS CORPORATION.- Oct. 20, 1955 [Nov. 8, 1954], No. 29998/55. Class 103 (1). [Also in Group XXIV] A planetary change-speed gear includes three cone reaction brakes as follows. In the case of two of the brakes their rotatable and axially movable cones 62, 89 are movable rearwards by fluid pressure to engage fixed outer cones 63, 90 for braking, and also take engaging thrust on disc clutches 70, 95, which thrust moves the cones 62, 89 axially forwards to disengage the brakes. The front brake cone 62 is engaged with its fixed cone by applying fluid pressure at 371 to a single chamber of an annular piston 67. The rear brake cone 89 is engaged with its fixed cone by fluid pressure applied through lines 345, 312, the former including an exhaust by-passed restrictor, to a large outer chamber 92 and small inner chamber 92a of a stepped piston formed by the brake cone 89 itself. The rear brake cone 89 is disengaged from its fixed cone also independently of clutch pressure by applying fluid-pressure through a line 231 to act forwards through the planet carrier on the gear suns and integral brake cone. The teeth of the gear trains are cut to a helix angle of 35 degrees to render the brakes self-energizing under drive torque. The third brake, used for reverse, comprises an internal and externally coned ring 106 splined on the planet-carrier 104 to be arrested, and clamped against a fixed outer coned ring 115 thrust axially forwards through a diaphragm lever-spring 112 by an annular stepped piston 108 which, for gradual engagement, has two operative chambers, an inner 110a which the fluid-pressure supply line 246 feeds directly, and an outer chamber 110, fed through a restrictor 252 which is by-passed for rapid release on exhaust, by a one-way valve 251. All the brake surfaces are of bronze and steel, have intersecting grooves, and a cone angle of eight degrees. Specification 793,616, [Group XXIV], is referred to.

Abstract: 1,150,824. Rolling. INSTITUT CHERNOI METALLURGII. 29 June, 1967, No. 30102/67. Heading B3M. [Also in Division G3] Apparatus for automatically maintaining the tension of a rolled product constant as it passes between two stands 11 and 11<SP>1</SP> of a continuous mill, includes a tension meter 1 which is connected through a comparison element 2 to the drive 7 of one of the stands. Initially, for obtaining a desired tension value, the meter is connected through a switch 6 to a servosystem 4 which acts in a follow-up mode without being connected by switch 5 to the drive 7. A tension signal from meter 1 is fed as a voltage to an automatic potentiometer 12 where it is modulated at 34 and amplified at 13. An actuating motor 14 moves a slide 36 until the input voltage of the potentiometer is compensated for. The slide 36 is held at a desired value when an operator throws the switch 6, the servosystem then acting as a memory unit with which the incoming tension signal is compared in the element 2. Differences between the measured tension and the desired value are now automatically fed to the drive in a sense to control the roll speed of one stand to reduce the tension difference.

Abstract: 1,174,254. Reactors. CANADIAN GENERAL ELECTRIC CO. Ltd. 16 Nov., 1966, [20 Nov., 1965], No. 30241/69. Heading G6C. [Also in Division F2] A valve 120 having an inlet passage 125 and outlet passage 123 is controlled by a ball 131 mounted on trunnions 133, 134 and actuated by a splined shaft 93, a passage 132 through the ball being aligned with the passages 123, 125 when the valve is open. A valve sealing member 140 slidably mounted in a recess 142 for radial movement with respect to the ball 131 has an annular metallic sealing 143 of relatively soft material such as nickel. When the valve is closed the seating 143 slides on to an annular seat 144 of a hard material, e.g. Stellite (Registered Trade Mark), surrounding the passage 125 and the pressure existing in the passage 123 forces the member 140 against the seat. To prevent damage to the seating 143 when the valve is opened, the sealing member 140 is lifted by hydraulic pressure applied at the inlet passage 125 before the shaft 93 is rotated. In a modification (Fig. 3, not shown), the ball 131 rotates about an axis at right angles to the axis of the passages 123, 125, 132 and a spring biases the sealing member 140 out of the recess 142. In another embodiment, Fig. 4, the member 140 has a lip 146 which rubs against the inside of the valve housing to reduce wear of the seating 145 as it slides over the seat 144. The valve 120 is intended for connection to the lower end of a calandria tube 101 of a nuclear reactor and when the ball 131 is in the closed or partially open position it supports fuel elements situated in the tube through the intermediary of a shielding plug (not shown). This plug has bearings on its lower surface which interlock with grooves 150 in the ball 131, whereby the ball is prevented from moving to its fully-open position until the probe of a fuelling machine (not shown) has been raised through the passage 132 to support the weight of the plug and fuel elements.

Abstract: 845,497. Wood grinders. NORTON CO. Sept. 24, 1958 [Nov. 13, 1957], No. 30478/58. Class 59 A method of producing wood pulp comprises simultaneously rotating and axially feeding successive logs across the operative face of a rotating grinding wheel in a direction to cause the wheel to remove bundles of fibres. The method is carried out in a machine wherein the logs are axially fed on a series of pairs of log-supporting rollers 45, 46 and 47, 48 beneath a plurality of grinding wheels 20 each driven by a separate motor. At least one of the sets of rollers (45, 46 or 47, 48) is driven through a sprocket and chain by a motor 61 so that the logs are rotated at the same surface speed as the rollers. Axial feed of the logs is effected by a link chain 82 which is driven by a motor 75 over sprockets 81, 83 and provided with driving members 85. The chain is provided with rollers at spaced intervals which ride in guideways 91, 92, Fig. 3, to support the actual driving portion of the chain. Brackets 49, 50 carrying the pairs of rollers 45, 46 and 47, 48 are adjustably mounted so that the grinding throat formed between the grinding wheels and rollers may be progressively decreased as the logs pass through the machine. By regulating the rate of axial feed, a depth of cut may be obtained such as to remove unbroken fibres or bundles from the logs. The grinding wheels, which may have "straight," conical or hyperboloid operative surfaces, are adjustably mounted as shown in Fig. 3 to permit the axis of the log passing through the machine to make an angle with the mid-plane of the wheel within the range of 10 to 25 degrees. A plurality of frusto-conical grinding wheels of the kind shown in Fig. 10 may be angularly positioned about the periphery of the log. As the logs reach the end of the machine, their small ends are disintegrated by a grinding wheel 20k located beneath the final grinding wheel 20. Coolant fluid may be passed to the logs through pipes 101, 103, 105, 106 to nozzles 107 carried by the grinding wheel hoods 100. A chemical solution, such as the sulphites or bisulphites used in the paper-making industry may be passed through the coolant system for the purpose of impregnating the surface of the logs and easing the removal of the fibres; if desired, this system may be arranged so as to immerse the logs in the solution. The machine may be so constructed that feeding of the logs is effected vertically or at an angle between the horizontal and vertical.
