Granted: 1899-12-09
Abstract: 15,072. Klatte, O. July 21. Metal pipes and tubes.- Tubular blanks are rolled in a universal or platerolling mill, to produce seamless bodies, such as cylinders, boiler pipes, tubings, fighting - masts, flame tubes, &c. Fig. 1 shows a universal mill having a pair of vertical rolls 2, (of which only one is shown), and a pair of horizontal rolls 1. The rolls are geared together so that the pass between each pair can be adjusted, the two pairs forming a pass in which is centrally placed a mandrel 4 carried i n bearings 6, 7. The mandrel has rings 5 on which the blank is rolled, and these rings are brought opposite the pairs of rolls by adjusting the mandrel by screws 8. The bearing 7 is carried by a ram, so that it may be lowered while the blank is placed on the mandrel, which is then held by a divided ring and chain 12. The mandrel is made in three portions, cottared together as shown in Fig. 2. The blanks, which are formed in any suitable way, may have spiral or other undulations, as shown in Figs. 2 and 3. The mandrel is rotated, when desired, by a rack 10 and pinion 9. The blanks may also be rolled in a two-high mill, having suitable grooves, the mandrel or rolls being displaced laterally to roll the blank in different grooves. In the plate-rolling mill shown in Fig. 8, the mandrel 36 has sleeves 31 on which the blank is rolled by the upper roll 32. This roll can be raised and lowered by hydraulic cylinders 33, 35. The end 45 of the mandrel is formed square, to fit in a bearing-block 46. The mandrel is carried in bearings 37 on a slide 38 and is connected to a ram 39, so that it may be withdrawn to allow the work to be placed in position on rolls 49 carried by bars 48, which can be vertically adjusted by a ram 47. The mandrel has tommy holes 44, so that it can be turned for the end to register with the block 46. Flat plates may be produced by cutting open and straightening the rolled tubes. If the rolls have suitable grooves, cylinders may be formed with strengthening-ribs, or may have end flanges. Vertical end rolls may be provided to assist in forming the flanges. Conical rolls may be used to form conical tubes.

Title: Improvements in the Separation of Gases from their Mixtures, especially Oxygen and Nitrogen from Atmospheric Air and Apparatus therefor.
Inventor: LEVY RENE JACQUES
Filed: 1902-07-26
Granted: 1903-07-25
Abstract: 16,615. LÚvy, R. J., and Helbronner, A. July 26. Oxygen; nitrogen.-The invention is described for separating oxygen and nitrogen from air, but is applicable for separating other gaseous mixtures into their constituents. A column a, protected from loss of cold, is divided by partitions b into say, twelve compartments 1 to 12. Each plate has an overflow pipe d<1>, or a valved outlet as shown to the lowest plate b<1>. Each plate, excepting b<1>, has a central opening with a tube c' covered by a hood g having a star-shaped flange with end projections resting upon the p'ate, which forces ascending gases to pass through the liquid in the tray. To start operations, liquid air is poured into the top compartment through an inlet P, and overflows so as to charge each compartment as high as its outlet. Dry compressed air is cooled as explained below, and is then led through tubes e, e', e<2>, e<3> to coils E, E<1>, E<2>, E<3>. The liquid air formed collects in the tube F, and is delivered to the top chamber 12. As it overflows from compartment to compartment, it meets ascending gases, the result being that as it flows downwards it takes up more and more oxygen from the ascending gases, at the same time giving up nitrogen thereto. When working properly, a gas exceedingly rich in nitrogen escapes through the outlet M, while practicallypure liquid oxygen collects in the lowest compartment, and is evaporated by the incoming air, so that pure oxygen gas leaves at N. The compartment 2 is deeper than the others, and is cut up into four small compartments by partitions of varying heights, the liquid overflowing from one to the other. The cold nitrogen gas and the cold oxygen gas pass through separate heat-exchangers to cool down the air to be afterwards separated, such air having been previously compressed and dried. The pressure employed is regulated so as just to keep the process working continuously, or, if desired, liquid air may be occasionally added at P to make up for unavoidable loss. The invention is not limited to the precise form of apparatus shown. The plates b may vary in form and number, and a second perforated plate may be arranged beneath each plate and the overflow tubes bent so as to deliver the liquid on to it. In the Provisional Specification the arrangement shown varies slightly, namely:-(1) filters are interposed in the tube F to separate out solid carbonic acid, (2) the pipe F passes downwards to the chamber 10, valves allowing the liquid air to pass as desired to the chambers 11 and 12, (3) the gaseous air is admitted to the two bottom compartments only, and (4) the previous compression of the air is as low as possible.
