Title: Improvements in or relating to dyeing apparatus
IPC: D06B3/32
Filed: 1921-03-24
Abstract: 183,526. Jackson & Brother, Ltd., Gass, G. P., Hammond, R., and Fish, J. R. March 24, 1921. Jigger machines.-In jigger dyeing-machines, padding or nip rollers are mounted in slidable bearings so that as one roller is moved into action against a bowl the other niproller is simultaneously moved out of action from a corresponding bowl, the movement being either done by hand or automatically when the reversing-clutch operates. The niprollers 1 mounted in bearings 3 are slid or reciprocated longitudinally over a frame 5 bv means of an eccentric pin 12 on a rocking shaft carrying an arm or tumbler 9. The arm 9 carries a frame 10 and a sliding weight 11 so that when the arm is moved by hand a little beyond the vertical the weight will slide to complete the movement and to transmit considerable and even pressure of the nip-roller against one of the driving-bowls 2. The arm 9 may have a fixed instead of a sliding weight. The bowls 2 have flanges 2a so as to retain a well of liquor in the zone between the two rollers. When the traverse of the cloth x through the machine is reversed by operating the lever 14 of a reversing dog clutch, a link connecting the clutch and the arm 9 may be used to throw over the arm 9 simultaneously.

Abstract: 723,672. Fuel-injection pumps. C. A. V., Ltd. June 9, 1953. [April 9, 1952] No. 9049/52. Class 102(1). A fuel-injection pump comprises a rotor d having one or more plungers f in radial cylinders and reciprocated bv a cam surface on the ring a. The rotor has a stem c which has a radial port that distributes the fuel to a number of outlets m each fitted with spring- loaded non-return valve 8 or a single non-return valve may be fitted to the passage h before the connection to the outlets. The stem c has spill ports r and the amount of injection is varied by adjusting a sleeve o relative to the stem ; the sleeve o may be rotated or moved axially. A second sleeve 3 may be adjusted to interrupt the flow of fuel to the pump during the suction stroke. When two plungers f are used, they may be pressed apart by a spring 13; in a modification, their outward movement is limited by the engagement of claws on their inner ends. One plunger may remain stationary by engaging a concentric surface on the ring a while the other engages a cam surface. The chamber e is filled with lubricant for the cam engaging surfaces.

Title: Improved Apparatus for Raising Sunken Vessels.
Inventor: JOURAVLEFF BORIS
IPC: B63C7/16
Filed: 1916-06-27
Abstract: 116,297. Jouravleff, B., Rylke, A., and Mendeteeff, B. June 27, 1916 Drills.-Rotary drills employed for connecting lifting apparatus to sunken vessels are controlled by a series of devices shown separately in Fig. 2. The motor 29, Figs. 1 and 2, drives a common shaft 25 from which each drill shaft 2 is driven through a clutch 26. A pump 32 forces water through a pipe 45 to a cylinder 46 to release a stop 48 from the shaft 2; thence the water passes through a pipe 49, valve box 19, and pipe 52 to a cylinder 31 to feed the drill shaft 2 forward. When the ship's plating is penetrated, a stopring 6, Fig. 3, frictionally engages the plating and through gearing 14, 13, 12, 11, 10, 9, 8 causes rotation of a cam plate 7 which engages racks on stops 5 which move outwards, cutting away any obstructions, simultaneously, a shaft 15 rotates a threaded shaft 17 which moves rearwardly and acts through a lever 18 and link 53 to move a lever 54, Fig. 8, whereupon a spring 55 moves a valve 50 to cut off the supply pipe 49 from the cylinder 31. The water from the pipe 49 then depresses a piston 57, so causing a valve 59 to open the cylinder 31 to exhaust and passes through a pipe 58 to a cylinder 61, moving the piston therein, and through links 64, 65, 66, freeing the clutch 26, to stop rotation of the drill. From the cylinder 61, the water passes through a pipe 62, a valve box 38 similar to the valve box 19, and a. pipe 67 to a cylinder 68 to cause engagement of a friction clutch 43, and thereby, through chain and worm gearing 39, 40, 41, rotate the screws 34 which act through a sleeve 33 to draw the shaft 2 rearwards. When the stops 5 engage the ship's plating the increased resistance causes the screws 34 to compress spring or fluid buffers 35 and act through a link to effect reversal of the valves in the valve box 38, whereby the cylinder 68 is opened to exhaust and the clutch 43 is disengaged. If desired, a single valve box 19 and 38 may control a number of drills.

Title: Destructive hydrogenation
IPC: C10G47/00
Filed: 1942-07-03
Abstract: 564,571. Destructive hydrogenation. TRIGGS, W. W. (International Catalytic Oil Processes Corporation). July 3, 1942, No. 9232. [Classes 1 (i) and 32] In the destructive hydrogenation of hydrocarbon oils to obtain motor fuels at temperatures between 500 and 1000‹ F. and pressures from 60-1000 atmospheres, hydrogenating gases containing from 40-85 mol. per cent of methane are used in conjunction with a hydrogenating catalyst comprising small amounts of a metal catalyst of the iron group deposited on siliceous material. The catalyst may consist of 1-15 per cent of nickel, cobalt or iron deposited on aluminium silicate, synthetic gels of silica or alumina or magnesia or acid treated clays of the bentonite or montmorillonite type. The carrier may be pretreated with fluorine or fluorine compounds. Oil, e.g. gas oil or kerosene, preferably having a sulphur content below .05 per cent, is fed from a supply tank 1 and mixed with hydrogenating gases from a tank 1a and methane from a compressor 10 is passed through a heating coil 6 upwardly through a reaction chamber 14 packed with catalyst. The reaction products pass through a cooler 17 to a high pressure separator 19 where gaseous products are removed and recycled through line 20. The liquid condensate then passes to a low pressure separator 22 from which vapours and further gases are separated, which may be also recycled through line 24. The residual condensate is passed to a fractionating tower 26 from which a fraction boiling in the gasoline range is withdrawn through line 27 to receiver 28 while bottoms are recycled to mix with fresh feed through line 32. The catalyst is prepared by impregnating the activated carrier with a solution of the nitrate &c. of the metal, extruding the plastic mass obtained and drying it at 300-400‹ F., followed by heating at 500-800‹ E. for 10-12 hours to decompose the nitrate to oxide. The oxide is then reduced in a current of hydrogen at 600-900‹ F. followed by treatment with sulphur-containing gases.

Title: Improvements relating to internal grinding machines
IPC: B24B49/04
Filed: 1937-04-01
Abstract: 491,666. Internal - grinding machines. CHURCHILL MACHINE TOOL CO., Ltd., and ASBRIDGE, H. H. April 1, 1937, No. 9274. [Class 60] In an internal - grinding machine wherein the work head a, Fig. 1, is reciprocated and the grinding head f is given a cross-feed, a work gauge g, carried by a spindle h, secured to a cross-head i slidable on bars k on the head a, is held away from the workpiece d by a spring- loaded plunger r acting on the cross-head until the grinding operation is approaching completion, whereupon a cam 12 on the feed spindle 9 closes contacts 14, 15 so as to energize a solenoid s which retracts the plunger r and allows a spring p to move the gauge up to the work. An adjustable stop 4 coacts with the cross-head i to prevent contact of the gauge with the grinding- wheel e. The stop is constituted by a lever pivoted to the machine bed, movement of the lever towards the head a being limited by an adjustable screw while the lever can move freely in the other direction. The head a is reciprocated by an oscillating frame v. The feed of the table f carrying the grinding head is produced by a cam 8, Figs. 3 and 4, on the spindle 9 engaging a lug 7 depending from a slide 6 movable in an inclined recess 23 in the table, the lug being maintained in engagement with the cam by a balance weight 10 acting on the table. When the gauge g enters the workpiece, contacts m and n, on the crosshead i and head a respectively, close, causing energization of a solenoid o. The armature 16, Fig. 4, of the latter is thereby moved to the left, and, through a lever 17, the slide 6 is moved in the direction of the arrow 22, whereby the grinding-wheel is retracted radially from contact with the workpiece. Specification 424,261 is referred to.

Filed: 1932-04-02
Abstract: 399,477. Thermionic valves. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. April 2, 1932, No. 9513. Convention date, April 2, 1931. Drawings to Specification. [Class 39 (i).] The dimensions and spacing of the cathode, control grid, and anode are such that, when the standard heating energy with which the valve is normally designed to work is applied to the cathode, the ratio of the steepness to the heating energy of the cathode is a maximum regarded as a function of this heating energy, the steepness being the greatest slope of the anode current-grid voltage characteristic for negative grid voltages. Small departures of the ratio from the maximum are admissible within the range of ratios corresponding to variations of 20 per cent in the heating energy from its value for the above maximum. A definite steepness is thus obtained with a minimum of .cathode-heating energy. In practice, the cathode is larger and at a lower temperature than cathodes of known valves. Dimensions are given for a valve with a long indirectly heated cathode of rectangular crosssection surrounded by a helical wire grid and by a plate anode.
