Abstract: 511,025. Hinges. GIBBONS, F. J. J. Feb. 14, 1939, No. 4810. [Class 65 (ii)] Pivoting adjustments. In a friction pivot, particularly for windows, of the kind comprising a cylindrical socket 1 and a cylindrical pintle divided longitudinally into two parts 5, 6, one of which is fast with a fixing plate, with a setscrew to adjust the separation of the parts 5, 6 to vary the friction in the pivot, the set-screw 8 is threaded transversely in one part of the pintle and does not normally project radially from the pintle, and the socket 1 has a radial aperture 3 for the insertion of a tool to rotate the screw. In the form shown, the screw 8 enters a recess in the part 5 of the pintle, which in this case is the fixed part.
Patent GB-449101-A (GB)
Title: Improvements in or relating to methods and apparatus for effecting intimate contact between liquids and gases
IPC: B01D47/02
Filed: 1935-02-14
Abstract: 449,101. Treating liquids with gases. BLAW-KNOX CO., Blawnox, Pennsylvania, U.S.A. Feb. 14, 1935, No. 4833. Convention date, Nov. 2, 1934. [Class 55 (ii)] Intimate repeated contact is effected between liquid and a gas by continuously entraining liquid from a batch by the gas and causing it to be lifted up one or more openended vertical tubes having their lower edges just above the liquid surface, a difference in pressure causing the gas to pass through the apparatus at high velocity and entrain liquid so as to form spray within the tubes. A tank 2 contains liquid to be treated by gas in a contact unit 4 to which it is connected by a valved pipe 9. Treated liquid is returned by a pipe 15 to a settling compartment 17 of the tank. The contact unit comprises a chamber divided by a partition 7 into upper and lower compartments 5, 6, which communicate through a vertical tube 8. Treating gas is forced by a blower 12 into the lower compartment 6 and passing over the liquid surface and beneath the release edge 13 of tube 8 atomizes liquid and carries it up the tube whence it is deposited on the partition for return to the tank. A modified apparatus employing gases other than air, which is prevented from contacting with the liquid, or for operation at super-atmospheric pressures, comprises a closed tank connected with a contact unit by a vent pipe in addition to the liquid supply and return pipes, and a gas return pipe is also provided from the unit to the blower for effecting a re-circulation of part or whole of the gas. A heater or cooler may be included in the system. In examples the treatment of calcium hydroxide with carbon dioxide and the oxidation by air of ferrous sulphate in a pickling solution are described. Specifications 312,457, [Class 55 (ii)], and 449,102 are referred to.

Title: Improvements relating to winding mechanism for clock movements and the like
IPC: G04C1/12
Filed: 1922-02-20
Abstract: 175,659. Landis & Gyr Akt.-Ges. Feb. 21, 1921, [Convention date]. Winding-apparatus, electric. -A winding. mechanism for clocks &c. comprises a screwed spindle c, carrying a nut i and toothed wheels d, e, the wheel d being rigidly attached to the spindle and the wheel e loose on it. The wheel e, which may be driven by a Ferraris winding- motor, rotates at a higher speed than the wheel d and spindle c, and, in consequence, the nut i is displaced towards the wheel e. When the movement is completely wound, the nut i locks the winding-motor by means of a spring wire k engaging on the periphery of the Ferraris disc f. When running down, the wheel d and spindle c driven by the clock movement rotate as shown by the arrow on the wheel d, and the nut i moves laterally towards d until the wire k releases the disc f and winding re-commences. If the current fails and the nut i is further displaced towards the wheel d, pins l, m on the nut i and wheel d lock together and prevent a complete unwinding of the spring The locking of the motor may alternatively be controlled by electrical means operated by the nut i.

Filed: 1920-02-19
Abstract: 163,477. Gledhill, A., and Radcliffe, A. Feb. 19, 1920. Rearing-appliances.-Relates to brooders of the kind heated by circulating pipes from a hot-water boiler placed outside the brooding chamber. The boiler J is heated by the lamp K and fed by a pipe N from a supply-tank M. The circulating- pipes G, H are in the form of two coils connected by a junction-piece, from which an air pipe P with check valve leads to the supply-tank M. The pipes G, H are arranged within a casing C with a metal cover F which conserves the heat and deflects it upon the chickens on the adjustable floor R. An air discharge passage D is thus formed between the casing C and the walls E of the brooder.

Title: Improvements in or relating to lifting dogs and like appliances
IPC: B66C1/42
Filed: 1938-02-21
Abstract: 492,867. Lifting-dogs. SOMERS, Ltd., W., and SOMERS, F. J. Feb. 21, 1938, No. 5335. [Class 78 (iv)] Lifting-dogs are locked in the open position and released automatically by a member which moves axially under the influence of the gripapplying movement of the lifting chain and is also moved angularly with respect to a second member carried on or influenced by the movement of the jaws ; the two members becoming alternately locked and free as the spindle makes successive quarter turns in the same direction. As shown in Figs. 1 and 3 a pair of pivoted crossed gripping arms 1 are connected by toggles 3 to a chain hook 6. One toggle link carries a casing 11 formed with two sets of staggered cam surfaces 9, 12. A spindle slidably mounted in the casing carries a pair of projections 14 for engaging the cams and laterally-projecting feet 18 for engaging the slot 17 on the jaw arm 1. When the load is lowered on to the ground and the lifting chain slackened, the toggles fall relatively to the gripping arms, and the spindle is first pushed to the base of the slot 17 and then raised. On this upward movement it is turned through 45‹ by engaging the cam surfaces 12. The initial pull on the lifting chain then raises the casing 11 relatively to the spindle and so causes the cams 9 to give the spindle a further turn through 45 degrees. This completes the movement of the foot 18 necessary to bring it into alignment with the undercut recess 17 and so lock the jaws in the open position. This movement is repeated in lowering the open jaws over a load, the spindle making two further rotations of 45‹ in the same direction as before and so reaching an unlocked position. The locking means can be fitted also to dogs in which the two gripping arms 1 are mounted on separate pivots spaced apart.

Title: Improved means for feeding liquid fuel to a carburettor of an internal combustion engine
IPC: F02M37/02
Filed: 1935-02-22
Abstract: 448,573. Vacuum apparatus for raising liquids. BENDIX AVIATION CORPORATION, South Bend, Indiana, U.S.A. Feb. 22, 1935, No. 5667. Convention date, Feb. 23, 1934. [Class 102 (ii)] [See also Group XXVII] In a fuel feeding system for a carburetter in which fuel is drawn by suction from a low level tank to a fuel chamber higher than the carburetter and adapted to feed it by gravity, the suction is created in the chamber by connecting it to the throat of a Venturi in an air duct or passage in the carburetter. A pair of spring- pressed flap valves 94 is mounted in the mixing tube 14 between main Venturis 30, 32 and the throttle valve 36 and is byepassed by a pair of Venturis 80, 82 which open into the space between the valves 94, 36. In the first Venturi 80, suction is assured when the throttle 36 is closed, by a passage 100 connecting the tube 14 below the throttle with the throat of the Venturi. A tube 76 connects this throat to a port 74 on a fuel chamber 54 to permit fuel to be drawn into the chamber from a low level tank 84 when a slide valve 68 is displaced to the left by a lever 60. The lever pivots about a pin 78 about which a float 58 turns and a spring 66 connecting an arm 64 on the float to the arm 60 compels the arm to snap across its dead centre position relative to the pin 78 as the float rises and thereby displace the valve 68 to the right to close the port 74 and open an atmospheric port 72. Fuel now flows past a non-return valve 106 to a float chamber 24. When the float has fallen sufficiently, the arm 60 snaps across to move the valve 68 to the left to close the air and open the suction port 74. In a modification, Fig. 5, an arm 154 on the float 144 rocks an arm 150 connected by a spring 156 to a second arm 16 which operates a slide value 146 and is pivoted at 152 to the arm 150. The Venturis 176, 178 for drawing in fuel to the chamber 142 are disposed at right angles to one another.
