Title: Improvements in or relating to the purification of hydrogen or other difficultly liquefiable gases
IPC: F16G3/08
Filed: 1924-11-05
Abstract: 238,175. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Aug. 5, 1924, [Convention date]. Separating gaseous mixtures by liquefaction.-In the manufacture of hydrogen by partial liquefaction of water gas &c., the completion of the removal of carbon monoxide and any methane present is effected by expanding the hydrogen for example down to atmospheric pressure, introducing liquid nitrogen into the expanded hydrogen and allowing it to evaporate and lower the temperature and circulating the cold gas thus obtained round the tubular system in which the final condensation of the gases accompanying the hydrogen is effected under pressure. The same method may he used in the purification of other gases, an appropriate liquefied gas being substituted for the nitrogen. The compressed gas to be treated after being freed from the bulk of the carbon monoxide and methane by partial liquefaction, is admitted through an inlet A to a liquefaction apparatus C, the liquid produced being withdrawn by a valve R and the residual gas passing through tubes F. From these tubes it passes to an expansion engine M from which it passes through a vessel D having baffles, into which liquid nitrogen is introduced from a liquefier L around the tubes of which the hydrogen passes before reaching the expansion engine. The very cold mixed hydrogen and nitrogen thus produced are circulated around the tubes in the liquefier C. The liquid nitrogen may be used to complete the separation of carbon monoxide from the hydrogen in a rectification column. If the gaseous mixture contains nitrogen, the nitrogen may be separated for use in the process. Coking processes.-When the hydrogen is obtained from coke oven gas, the quantity of nitrogen present in the gas may be increased by admitting suitable quantities of air to the retort.

Title: Improvements in or relating to casting
IPC: B22D11/14
Filed: 1956-08-30
Abstract: 839,556. Casting-machines. BRENNAN, J. B. Aug. 30, 1956 [Oct. 10, 1955], No. 26513/56. Class 83 (1). A casting method comprises feeding molten metal into a cavity in a passage, the extremes of the cavity being defined by two plugs, and moving the plugs to carry the material along the passage to eject it from the passage in a shaperetaining form. Molten or solid metal in particulate form is fed to an electricallyheated container 1, and degassed by maintenance of a vacuum therein. A die 7 extending downwardly from the container has a zone heated by a high-frequency coil 8 and a zone cooled by a cooling unit 9. Extending upwardly and vertically reciprocable through the die, is a rod 10 which defines the lower end of the casting to be made, and extending downwardly is a vertically reciprocable sleeve member 15 defining the upper end of a tubular casting, whose interior surface is defined by an independently vertically reciprocable rod 18. Thus when the mould ports 10, 15, 18 are moved downwardly in unison, a casting is carried through the die 7. Downward movement of the core 18 may then be stopped, so that the member 15 strips the solidified casting from the core, relative movement of the members 10, 15 then freeing the casting for lateral removal, e.g. by air-blast 21. During passage through the die the member 15 may be moved downwardly relative to the members 10, 18 so that the casting is compressed during solidification. The core 18 may be omitted and the part 15 may be solid to produce solid castings. Further, a series of wires may be cast by having grooves in the die 7 or around an enlarged head of the core 18, with the member 15 arranged to longitudinally strip the cast wires from said grooves. Mould and core materials.-The parts 10, 15, 18 are preferably made of Al 2 O 3 ,nitridedsilicon-carbide, quartz or graphite, and the die 7 is of graphite. Casting processes.-In an example, copper in the container is maintained at a temperature of about 2150-2300‹ F.

Abstract: 246,247. Abßlsamo, C. L. T. Nov. 6, 1924. Contacts.-Means for closing and opening electric circuits and applicable to lighting and extinguishing lamps, particularly in connection with scale or like devices having an oscillatory element, consist in arranging the circuit terminals in the form of tubes having portions of conducting and insulating material and conducting rods within the tubes on the ends of which rods rest balls which respectively close the circuit between the rod and the conducting part of its tube. In Fig. 1, the tube has conducting annular sections 1 - - 3, electrically insulated from one another and adapted to be engaged one at a time by a ball 7 resting on a vertical oscillatory rod 8. As applied to a scale, Fig. 2, lamps 34 - - 36 are connected to three tubes and indicate " under," " fair," and " excess " weight, respectively. Current enters the conducting tube 15 and passes through the ball 17 to one, 11, of four rods 11 - - 14, the latter three co-operating with tubes having conducting parts 18, 23, 27. The return lead passes through contacts 43 of a switch 39 having a handle 45 adapted to be engaged by the counterweight 46 of the scale pan to open circuit when the pan is in zero position. A like result is obtained by dispensing with switches 42 and making the lowest part of the tube 15 insulating, so that in the lowest position of the rods the circuit is broken completely. Current enters through the rotatable foot 47 of the scale, passing to bring plungers and conducting rings 54, 55 and thence by way of screws 57, 59 and leads 62, 63 to the switch 39 and tube 15.
