Title: Hydraulic jacks
IPC: B66F5/04
Filed: 1944-11-28
Abstract: 594,586. Hydraulic jacks. PAGE, H. E. Nov. 28, 1944, No. 23725. Convention date, Nov. 23. 1943.[Class 78(iii)] A hydraulic jack comprises a body in which a piston under the action of a spring ,is slidable in one direction, while upon application of pressure to a pressure chamber for the piston, the latter is forcibly moved in the same direction in which the spring acts thereon, and includes a pump for alternate connection with a pressure reservoir and the pressure chamber for the piston, said pump effecting protractive and retractive movements of the piston, while the spring effects protractive movement of the piston rotative to the body in the absence of action of the pump. A hydraulic unit, Fig. 2, consists of a body 11 with an inner end portion 11a pivotally mounted between side plates 5 by a cross pin 12. The body comprises a cylinder 15 with which a piston 16 is slidably mounted. The piston has a longitudinal bore housing a compression spring 22 tending to push the piston 16 outwards. The piston is held in the position illustrated by means of fluid pressure bearing on an annular shoulder 26 in an annular chamber 25 surrounding the piston. When the pressure in the annular chamber is released, the spring forces the piston outwards, tilting a lifting arm 6, and causing it to engage the load. Further lifting is effected by pumping fluid into the cylinder 15 from a reservoir R through a valve, Fig. 3. The pumping is effected by a small piston 36 moving in a cylinder 35. The piston is actuated by a lever H having at its end a yoke 37 pivoted at 38 to the side plates 5. The pivot 38 carries two arms 37a which are connected to two fork arms 39 which in turn are connected to the piston 36. Fluid drawn from the reservoir R passes through the valve 42, Fig. 3, controlled by a spindle 55. When fluid is drawn from the reservoir R into' the cylinder 35, it passes through a passageway 63 and past a poppet 75. On the pressure stroke of the piston 36, this fluid is forced past a ball valve 71 and through a passageway 81a into the cylinder 15 thus forcing the piston 16 outwards. To lower the jack, the valve 42 is rotated and by a cam 49 unseats the poppet 75 and ball valve 71 thus releasing the pressure in the cylinder 15. In this position of the valve, pumping of the piston 36 causes fluid to pass from the reservoir, past a poppet 67 and a ball valve 65, into the annular chamber 25, thus forcing the piston 16 back into its cylinder 15.

IPC: C21D1/613
Filed: 1928-08-23
Abstract: 297,796. Ges. f³r Industriegasverwertung. Sept. 28, 1927, [Convention date]. Tempering.-In a process for the heat treattreatment of iron and steel, the metal is heated to the usual annealing temperature, e.g. red heat, and then cooled continuously to ordinary or normal temperatures by a single immersion in a liquefied gas of low boiling point, e.g. liquid air. Instead of liquefied gas, a normal cooling agent such as oil or water may be used and the cooling is interrupted a number of times by the repeated withdrawal of the metal from the cooling agent and re-immersion, the duration of the cooling treatment being prolonged so as to approximate to that when liquefied gas is used and the average rates of cooling throughout the frequent intervals between successive immersions approximating to the rates obtaining when the liquefied gas is'used. The Specification as open to inspection under Sect. 91 (3) (a) states that the metal may be cooled by subjection to the action of a current of cold air at -140 to -170‹ C. as it issues from the expansion engine of a gas liquefying plant. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in liquid dispensing apparatus
IPC: G01F15/075
Filed: 1936-09-04
Abstract: 474,491. Dispensing liquid fuel. SAUSER AKT.-GES. Sept. 4, 1936, No. 24269. Convention date, Sept. 13, 1935. [Class 116] An apparatus for dispensing measured quantities of petrol &c. requires the indicators to be zeroized and the delivery hose nozzle to be removed from its support before the pump can be started. The hose nozzle has pins 11 which rest on an inclined support 12 so that the valve guard 8 of the nozzle is normally urged against the casing of the apparatus thus maintaining an abutment 25 of a lever system, which projects through an aperture in the casing, in the position shown. The lever 22 carrying the abutment 25 is pivoted at 23 and has a pawl 26 which permits only one-way movement of the lever 22 past a hook 21 at the end of a lever 18b pivoted at 19. A key-controlled boss 30 has one arm 36 adapted to engage a lever 34 to maintain fingers 37 on the pins 11 to prevent removal of the nozzle, and another arm 29 adapted to close an electric contact 31 on to a metal spring 32. An arm 22b fast on the lever 22 is adapted to close an electric contact 28 on to the spring 32. Before dispensing can take place the counter 16 must be zeroized by movement of a hand-operated auxiliary shaft, this movement allowing the lever 18 to turn under the influence of the spring 20 to release the lever 22. The key-controlled boss 30 must then be turned to lift the fingers 37 to release the hose nozzle and to close the contact 31 on to the spring 32. Flow cannot commence until the nozzle is removed from its support thereby releasing the lever 22 which causes the arm to close the contact 28 on to the spring 32 thus completing the circuit through the pump motor and commencing flow. The lever 17 returns to full line position at the termination of the dispensing operation, thus setting the hook 21 which automatically locks the lever 22 when the hose nozzle is replaced on its support. Specification 474,489 is referred to.

In an arc welding device for butt welding tubes 10, 12, a torch 14 having a tubular shield 22, e.g. of a ceramic, is mounted on ring members 17, 19 with the axis of the shield parallel to the axis of the tubes 10, 12 and is rotatable about the tubes, and an electrode 20 projects radially inwards towards the joint through an aperture 24 in the side wall of the shield 22. The ring members 17, 19 are enclosed by a cylindrical or square casing 40 at least a part of which is transparent and argon is passed through the shield 22 and the aperture 24 and is piped from the interior of the casing 40 to the interior of the tubes 10, 12. The electrode 20 is a tungsten needle mounted in a ribbed mild steel holder 26 to which the supply cable 30 is connected. A clamp 42 fixed to the tube 10 carries a worm 44 driven by a motor and engaging a worm-wheel on the rotatable ring member 19. The ring member 17, which is a loose fit on the tube 12, is steadied by spring-loaded balls 48. The tubes are first tack welded by the electrode 20. Subsequently the arc is struck and after complete penetration has been achieved the torch 14 is rotated to complete the weld with a slight overlap. The current is reduced gradually to prevent formation of a crater. If desired, a fusible insert is placed between the tubes. The device is used for the welding of closely spaced tubes in a heat exchanger.

Title: Method and apparatus for indicating level of liquids
IPC: B63B39/12
Filed: 1920-08-25
Abstract: 150,349. Merrick, A. A. Aug. 25, 1919, [Concention date]. Draught, indicating.-Liquid-levels are measured by establishing during each individual indicating operation a column of the liquid which is connected to a normally balanced gauge column, the first mentioned column being brought to a pre-determined height by changing the pressure in the connexion between the columns. Primary applications are the sounding of a ship's ballast tanks, and the measurement of a ship's draught. In the general form, shown in Fig. 4, a U-tube mercury gauge 12 fitted with a scale graduated on one side for oil and on the other for water, is connected at the inner limb by a pipe 13 to the top o! a second column member 11, fitted at the bottom with a valve 10 and a pipe 9 common to pipe leads from the ballast tanks, each lead being fitted with a valve 6. The pipe 13 is connected to a vacuum producer or condenser 15 by a pipe 14 having a needle valve 19 and an air valve 21. To measure the level in a tank below the indicator the particular valves 6, 10 and 19 are opened until the liquid rises in column 11 to a mark 0, 0, when the valve 19 is closed. The level in the tank is indicated by the difference of levels in the U-tube. To measure the level in a tank above the indicator, the valves 6, 10 and 21 are opened until the pressure of the air compressed in pipe 13 is reduced sufficiently to allow the liquid in column 11 to rise to the level 0, 0, when valve 21 is closed. By fitting a column 11 to the pipe from each tank, and connecting the tops of these columns by a common pipe 13, the soundings of a. plurality of tanks may be taken at the same time,. the tubes 11 also being calibrated. In another method, the tube 11 is calibrated, and a sufficient vacuum produced in the pipe 13 to draw all the mercury into the inner leg. The mercury gauge may be replaced by a pressure and vacuum gauge, correction being made in this case for atmospheric pressure. To adapt the gauge for measuring the draught of a ship, the pipe 9 is fitted with a sea-connexion at a known vertical distance below the indicator. In every case the vertical distance from the indicator to the bottom of the tank must be known. A correction is applied in the case of a ship with a list by measuring the angle of inclination by a clinometer, &c. The effects of rolling and pitching are obviated by making the pipe 9 of small bore and by throttling the supply to the indicator through the valve 10.

Abstract: 1426613 Magnetic separators KRUPPKOPPERS 24 May 1973 [15 June 1972] 24999/73 Heading B2J Apparatus for separating fine magnetizable material 5 from coarser material 6 comprises a conveyor belt 1 for transporting the material whilst subjecting it to vibratory motion, and magnetic means associated with the delivery end 4 of the conveyor belt. As shown, the magnetic means includes a belt 7 having a plurality of magnets secured over its whole length, the belt extending around the reversing roller 8 for the belt 1 and around a roller 10 in the region of a delivery point defined by a funnel 11 and a scraper 12. Thus, the fine material 5 which tends to collect on the surface of the belt 1 because of the latter's vibratory motion is carried around the roller 8, by virtue of the attractive force exerted by the belt 7, for delivery into the funnel 11, whilst the coarser material 6 falls from the belt 1 as shown. The supporting rollers 2 for the top run of the belt 1 have uneven surfaces which import the necessary vibratory motion to the belt; alternatively, the supporting rollers may be eccentrically mounted and/or of different sizes, or the belt may be associated with a vibrating table. The magnets may be of the permanent or electromagnetic type. In a second embodiment, a magnetic reversing roller is provided at the delivery end of the conveyor belt 1 and a plurality of stationary magnets, located close to the inside face of the bottom run of the conveyor belt, extend from the reversing roller to a required delivery point for the fine material.
