Title: Oxidation of hydrocarbon drying oils
IPC: C08C19/02
Filed: 1958-06-04
Abstract: Oily polymers of conjugated diolefines of 4-6 carbon atoms or oily copolymers such diolefines with each other or with other ethylenically-unsaturated compounds are oxidized by contacting the oil in the presence of a hydrocarbon-containing solvent in the form of a thin film in a packed column with oxygen, maintaining a pressure of at least 70 p.s.i.g. and continuously recycling the oil from one end of the column to the other.  The oil may be prepared by polymerizing butadiene, isoprene, p  dimethylbutadiene, piperylene, or methylpentadiene, alone, mixed with each other or mixed with minor amounts of styrene, paramethylstyrene, dimethylstyrene, diethylstyrene, acrylonitrile, methacrylonitrile, methyl acrylate or methyl methacrylate in the presence of benzoyl peroxide, cumene hydroperoxide, t-butyl hydroperoxide or metallic sodium.  A diluent may be present when using sodium.  The polymer may have a molecular weight up to 10,000 and a viscosity up to 22 poises at 50% N.V.M. They are oxidized with dried air at 70-1000 p.s.i.g. and 20-150 DEG C. while recycling the oil at a rate of 15-35 gal./minute/sq. ft. of tower cross-sectional area.  Catalysts may be present, e.g. naphthenates, octoates or oleates of lead, iron, cobalt, manganese or zinc, peroxides or dispersed alkaline salts.  The time necessary to introduce 10% oxygen into the polymer (#Q), the polymer charge in pounds (W), the pressure in p.s.i.a. (P) and the recycle rate in gallons per minute (G) are related by the equation: <FORM:0870092/IV (a)/1> Specification 766,225 is referred to.

Title: Improvements in and relating to driving and steering control mechanisms
IPC: B62D11/18
Filed: 1958-06-06
Abstract: 840,998. Steering vehicle by braking. NATIONAL MINE SERVICE CO. June 6, 1958 [Aug. 7, 1957], No. 18239/58. Class 79(2). In a vehicle such as an endless track mining machine 1 Fig. 3 in which the tracks 21, 23 are individually driven by hydraulic motors 41, 43 the normal steering by control of back pressure in the motor circuits is selectively replaced by a control which first releases a clutch C connecting the motors together for straight driving and then applies one or the other of brakes 109, 119 coupled to the motor drives. The motors 41, 43 are arranged longitudinally and drive the tracks 21, 23 through worms 50, 52 and gears 49, 51, and are coupled to coaxial brakes 109, 119 through chains 131, 135 and sprockets 107, 117 Fig. 4. The brake 109 is mounted on a shaft 83 rotating on bearings 85, 87 in the machine frame 1 and having a, clutch pressure plate 91 splined thereto at 89. The brake 119 is mounted on a bush 113 rotatable about the shaft 83 on a bearing 115 and coupled to one set of clutch plates 125 through splines 123. The other set of clutch plates 127 is coupled to the pressure plate 91 through pins 95 which interconnect with the clutch housing 77. The clutch is normally maintained engaged by springs 97 having adjustable backing rings 103, 105 but is releasable by hydraulic pressure in a cylinder 65 which moves a piston 59 against a spring 63 to actuate plungers 69 engaging an anti-friction ring 71 to move the clutch housing 77 axially The brakes are operated by hydraulic cylinders 185, 189 controlled by valves 193, 195 Fig. 5 having a common control lever 225 with the clutch operating valve 191. 'Initial movement of the lever 225 to either side first actuates the valve 191 through a forked push rod 209 to release the clutch. Further movement of the lever actuates one or other of the valves 193, 195 through push rods 211, 213. The system is an alternative to the normal control of steering by a lever 263 which actuates valves 251, 253 to vary the back pressures in the return lines 243, 245 of the hydraulic motors 41, 43. For turning the vehicle about an axis between the tracks, reversing valves 247, 249 are also inserted in the motor circuits.

Title: Improvements in or relating to the manufacture of paper
IPC: D21D5/04
Filed: 1948-07-07
Abstract: The separation of paper pulp fibres from paper-mill liquors (see Group VIII) is effected by passing the liquor through a screen which is mounted so that it is free to move in any direction in a horizontal plane the screen being caused to move with a circular movement of small amplitude while the liquor is passing through it. The liquor containing the fibres may be fed continuously on to the screen with a translational component of movement relatively thereto whereby the pulp fibres retained on the screen are maintained in such translational movement that they are continuously removed from a margin of the screen.  The screen may be slightly inclined to the plane in which it moves so as to direct the retained fibres continuously toward its lower edge margin.  Specification 658,190 is referred to.
