Abstract: 139,065. Hisamoto, J., and Toyo-Kagaku - Takin Kabushiki - Kaisha. April 23, 1919. Wire.-Relates to a method of drawing wire for electric-lamp filaments made of metal which is liable to become contaminated with carbon while being drawn or annealed, and consists in placing a slug or bar of refractory metal, surrounded by a refractory oxide, in a metal tube, drawing the assembly to filamentary size and removing the casing material. A slug of tungsten, tantalum, thorium, zirconium or of an alloy, consisting partly of one of the refractory metals, or of a suitable refractory composition consisting of a refractory metal and a non-metallic substance such as boron or silicon, is placed in a tube of either nickel, an alloy of nickel and chrome, steel, copper, or silver. A space is left between the slug and the tube, and is packed with thoria, magnesia, ceria or zirconia. The slug may be hammered or worked before or after being placed in the tube. The cylinder is drawn in the usual way. The compound wire is then cut into lengths, and the outer tube drawn, dissolved, or melted off. In the latter case the lengths may be placed in a flashing jar connected to electrical terminals. The jar is then ehausted, the current passed, and the tube melted from the wire. A double tube may be used comprising a copper, silver, or nickel tube in an outer steel case. The tube after drawing is dissolved off by hydrochloric or sulphuric acid and the last thin coating may be melted off.

Title: Rotary apparatus for pumping and like purposes
IPC: F04D23/00
Filed: 1923-04-16
Abstract: 214,456. Gillespie, W. M. April 16, 1923. Centrifugal e j, e c t o r pumps.-A rotor 4 forms one wall of an annular chamber containing a quantity of liquid and by its rotation keeps the liquid constantly swirling in the chamber. The passage of the liquid over the annular orifice between the rotor and the casing, draws air into the chamber which accumulates under pressure within the swirling mass of liquid and is taken off by an internally projecting pipe 11. The axial position of the rotor is determined by a balance between a spring 12 and the chamber pressure on the rotor ; the rotor moves accordingly and the breadth of the orifice varies in accordance with the delivery pressure. Two such pumps may be arranged in a.duplex machine symmetrical about a central plane and in which there is no axial movement of the rotor. Air is admitted through a hollow shaft and passes radially through central passages between the halves of the rotor which may have corrugated adjacent surfaces so as to provide circular or rectangular passages on a continuous annular-space of varying crosssection. The apparatus may be used for aerating liquids, for separating liquids from one another and for mixing.

Title: Hydrocarbon oil hydrofining and cracking process
IPC: C10G65/12
Filed: 1962-03-19
Abstract: Heavy hydrocarbon oils free of gasoline but containing nitrogenous compounds and hydrocarbons boiling above 415 DEG C. are cracked by (a) cracking in a first reaction zone to obtain an intermediate product having an end point of 400 DEG -435 DEG C. from which higher boiling materials are separated, (b) catalytically hydrofining the intermediate product to decompose nitrogenous compounds and (c) catalytically hydrocracking the hydrofined material to obtain a product having an end point of 340 DEG -370 DEG C., from which higher boiling materials are separated, at least part being recycled to the hydrocracking.  The process is based on the discovery that nitrogenous compounds are not wholly removed by hydrofining from materials boiling above 400 DEG -435 DEG C. but are from materials boiling below this range.  Accordingly a feed boiling in the range 200 DEG -540 DEG C. is preferably fractionated with a cut point of 400 DEG -435 DEG C., and the higher boiling fraction is fed to the first stage.  This may be a thermal or catalytic cracking step but is preferably a hydrocracking step effected in the presence of a catalyst containing a Group 6A metal and/or an iron-group metal using 500-1800 standard litres of hydrogen per litre of charge at 260 DEG -525 DEG C. and 1/3 -200 atmospheres and an LHSV of 0,3-10. Unconverted feed may be recycled.  The intermediate product is mixed with the lower boiling fraction of the feed and hydrofined at 260 DEG -540 DEG C., 20-200 atmospheres and an LHSV of 0,1-10 with 1801400 litres of hydrogen per litre using a supported catalyst containing 4-45% molybdenum and preferably also 0,2-6% of nickel, iron and/or cobalt.  After removal of gases including ammonia the third stage is effected at 200 DEG -510 DEG C., 30-100 atmospheres and an LHSV of 1-10 using 180-1100 litres of hydrogen per litre and a catalyst containing a Group 6A and/or 8 metal; where both types of metal are present the weight ratio of Group 8 to Group 6A metal will be 0,05-5:1.  The product is separated into gas, gasoline and middle distillate, higher boiling p  material being recycled.

A fan damper 21 in the main 17 is normally closed when no coke is being discharged from an oven chamber. After the flap 16 has been opened the valve 15 is closed and the fan damper 21 is opened to restore the partial vacuum in the main so that it may be ready to receive the fumes &c. during discharge of the oven (e.g. into a quenching car). After the pushing of the coke from the oven, retraction of the coke guide 10 and consequent deactuation of the switch CGLS causes the valve 15 again to be opened and the damper 21 to be closed, in order to decrease the partial vacuum in the main 17, thus enabling, after a time delay, the flap 16 to be closed. Subsequently the valve 15 is closed and the fan damper 21 is opened to restore the negative pressure in the main 17. The sequence initiated by the switch CGLS may if necessary be delayed by the operator using a sequence-delay start switch 12.
