Title: Tractor steering mechanism
IPC: B62D12/00
Filed: 1949-02-17
Abstract: 659,627. Motor vehicles. TRIGGS, W. W. (Caterpillar Tractor.Co.). Feb. 17, 1949, No. 4351. [Classes 79 (iii) and 79 (v)] [Also in Group XXIX] Steering mechanism applicable to the steering of a two-wheeled tractor articulated to a trailer, e.g. a scraper, comprises a lever 6, Fig. 3, pivoted at 7 coaxially with the connection between the tractor and the trailer parts of whose frames 11, 18, are shown, and hydraulic servo-devices 3, 4, 8, 9, each having a connection with the lever 6 and two being pivoted to the tractor frame and two to the trailer frame. Motive fluid supply conduits 41, 42 and passages 46, 47 within the pistons and piston rods of the servodevices together with connecting pipes 54, 55 are arranged so that pressure liquid supplied through one of the conduits 41, 42 causes the simultaneous extension of one pair 3, 8 or 4, 9 of the servodevices and retraction of the other pair. Gearing 61, 62, together with other gearing elements (not shown), restricts the angular movement of the lever 6 with respect to the frame 18 to half that of the frame 11 so that all the servopistons move equal amounts. The servodevices differ in detail from those shown diagrammatically in Fig. 3. A lever 97, Fig. 6, movable with a gear sector 94 meshing with a rack 93 on a nut 92 is connected by linkage (not shown) to the lever 6 so that rotation of a steering wheel 71, owing to the resistance to movement of the lever 6, causes axial displacement of a screwed shaft 83 splined at 82 for sliding engagement with the steering column 81 and consequent displacement of an arm 88 connected to a control valve for supplying either of conduits 41, 42 with pressure liquid. The resulting movement of the servo-devices and the lever 6 is transmitted to the gear sector 94 which returns the shaft 83 to its neutral position. Should the servo-mechanism fail the shaft 83 engages a shoulder at either end of its travel and operates the lever 6 directly. The control valve 76, Fig. 8, has a link 77 for connection with the arm 88 and is supplied by a conduit 107 with pressure liquid from a pump 109 and exhausted through a conduit 119 connected to a tank 75. The lands of the valve 76, where they coact with chambers connected to the conduits 41, 42, are formed with notches 76a by which the servo-devices are continuously subjected to pressure. A relief valve 127 limits the pressure in the conduit 107. A pump 108 of larger capacity than the pump 109 normally discharges through a chamber 131 and a conduit 132 to the tank 75, but its output is diverted to augment that of the pump 109 in the event of rapid operation of the steering wheel resulting in displacement of the valve 76 sufficiently to allow a pilot valve 112 coacting with a coned shoulder 126 to descend and place a conduit 114 in communication with a conduit 124, pressure in which depresses a valve 123. The pump 108 then discharges through a check valve 128. In a modification, the output from the larger pump is controlled directly by lands on the valve 76.

Abstract: 116,873. Easton, R. W. March 14, 1918. Charging and discharging.-Coal shale, peat, or other material is fed to, or conveved through, a retort, coke oven. or the like by two or more intermeshing screws driven by suitable at, one or both ends. The retort A is fed intermittently from a hopper D and the coal is conveyed through the retort by intermeshing screws B of the kind described in Specification 109,663 [Class 87 (ii), Moulding plastic &c. substances]. The lower part of the retort conforms to the screws as in Fig. 2 to avoid a space between the screws in which part of the charge might lodge. The charge passes to a receiving hopper E emptied. periodically. The screws may pass through the retort &c. as shown, or may be in a separate casing outside the furnace setting. Such an arrangement is described in connexion with a coke even. the interior of which is of gradually increasing cross section to facilitate passage of the charge. The screws are driven by suitable external gear C.

Patent GB-622735-A (GB)
Title: Improvements in or relating to processes for separating solid and liquid triglycerides from each other
IPC: C11B7/00
Filed: 1946-02-14
Abstract: Solid and liquid triglycerides are separated from each other by dissolving the mixed triglycerides in a semi-polar solvent of limited solubility in and for water, rapidly chilling the solution at a rate of not less than 0.75 DEG  C. per minute, in a continuous crystallizer wherein the cooling surfaces are scraped with minimum agitation, and then separating the precipitated solid glycerides from the liquid glycerides remaining in solution and separately recovering the solvent from each fraction.  A semi-polar solvent is defined as one which contains sufficient oxygen atoms in the molecule to have an attraction for water as indicated by a limited but definite solubility of water in the solvent and of the solvent in water.  Such a solvent ensures that water, if present, is precipitated from the fat solvent solution rather than the water displacing the fat from solution. <PICT:0622735/III/1> Suitable solvents comprise ketones, esters, ethers, aliphatic nitro compounds and compounds containing one or more of these groups.  Solvents specified comprise methyl ethyl ketone, methyl isobutyl ketone; isopropyl acetate, ethyl acetate; and ethyl ether.  These solvents give precipitates of discrete particles rather than amorphous slimy precipitates.  The process is applicable to the mixed triglycerides of animal, vegetable and marine oils such as hog fat and tallow, soya bean oil and cottonseed oil, and sardine and herring oil; and particularly to the inedible grade of hog fat known as white grease for the production of lard oil.  The rapid chilling with minimum agitation ensure reduced damage to the fragile precipitates.  The concentration of fat in the solvent is preferably 30 to 50 per cent by weight.  In a suitable plant for the process, the melted mixed triglycerides from a container 1 and the solvent from a container 2 are metered to a counter-current chiller 9 and therefrom through pipe 13 to a continuous rotary vacuum filter 14. The precipitate from the filter is melted and discharged to a continuous still 16, and the filtered liquid is discharged to a continuous still 18.  Solvent from the stills is condensed in a condenser 21 for re-cycling to the solvent container 2.  The chiller 9 comprises cooling conduits 10 surrounding chilling tubes 11 in which rotary scrapers 12 are disposed.

Title: Improvements in valve gear for internal combustion engines
IPC: F01L5/04
Filed: 1919-02-24
Abstract: 138,183. Scott, A. Feb. 24, 1919. Valves; valve-gear. - In a, four-stroke-cycle engine, separate piston valves f, g, for inlet, and exhaust of a group of four cylinders firing in succession, are operated by fluid pressure, the four inlet valves being worked by compressed air, and the four exhaust. valves opened by the pres. sure of the working fluid in their respective cylinders and closed by compressed air. Each valve comprises a pair of connected pistons y, z, Fig. 8, and a flat slide t free to move radially with respect to the valve, but moving axially with it, and working with friction against one or other face of a recess s, Fig. 3. The slides t protect the valves f, g from the explosion and give the frictional resistance necessary for the correct working of the valves. Each valve chamber is provided at each end with an inlet and an exhaust port such as k', k<2> for the actuating-fluid. Each working piston p, Fig. 4, contains a chamber p' which is placed alternately in communication with an air reservoir by ports r, n, and with pipes leading to the valve chambers by ports r, m. The ports m of the cylinder A' are connected to the inlet valve chambers of cylinders A<3>, A<4>, and to the exhaust valve chamber of cylinder A<4> the ports m of the cylinders A<2>, A', A<4> axe connected similarly to the valve chambers in cyclic order; and a piston-controlled port o in each working cylinder is connected to the exhaust valve chamber of the same cylinder. The cylinders fire in the order A<1>, A<2>, A<3>, A'. In operation, each exhaust valve is opened by pressure from the same working cylinder; the piston of cylinder A', soon after the commencement of its exhaust stroke, distributes compressed air to close the inlet valve of cylinder A', and to open the inlet valve and to close the exhaust valve of cylinder A<4>. The ports r in the piston register with the ports m leading to the valve chambers four times in each cycle, but on one occasion the air escapes from the open exhaust of one of the inlet valve chambers, and on two occasions there is no pressure in the chamber p<1>. The distribution of compressed air by the other pistons is similar.
