Inventor: LEVINSTEIN MOSES AARON
IPC: C23C10/28
Filed: 1967-08-18
Abstract: 1,189,697. Making hollow composite metal articles. GENERAL ELECTRIC CO. 18 Aug., 1967 [3 Jan., 1967], No. 38100/67. Heading B3A. [Also in Division C7] Hollow alloy articles are prepared by coating (e.g. by electrolysis or vapour deposition) a core (e.g. of A1 or Mg) with a shell of a higher melting point metal (e.g. Ni, Fe, Co, Cu or Ag) and heating the composite to above the melting point of the core but below that of the shell (e.g. at 1600-2200 F.) to cause the core to diffuse into the shell. The core and shell metals are so chosen that the core preferentially diffuses into the shell and the pressure during the diffusion heating is such as not to cause the collapse of the shell. Hollow wire, beads or powders as well as tubes may be made by this method. The core member may be formed as a screen or mesh to form a screen or mesh of hollow members.

Title: Process and apparatus for removing tar particles prior to the recovery of clean oils from coal distillation gases
IPC: C10K1/04
Filed: 1929-12-18
Abstract: 346,805. Gas-condensing processes ; pitch and tar. BARRETT CO., 40, Rector Street, New York, U.S.A.-(Assignees of Miller, S. P. ; Englewood, New Jersey, U.S.A.) Dec. 18, 1929, No. 38784. Convention date, Dec. 18, 1928. [Class 55 (ii).] In the removal of tar particles prior to the production of clean oils from coal gas &c. the gases from a number of coke ovens or retorts are passed through an intensive tar spray to remove tar or pitch particles before passing to the condensers. The spray is produced by rapidly rotating a horizontal cylindrical member dipping to a slight extent into a body of tar or pitch in a separating chamber. The gases are scrubbed at the temperature at which they leave the collector main ; this may be about 200‹ C., 300‹ C., or higher. The gases after scrubbing may be passed into sulphuric acid to produce ammonium sulphate. The scrubber 11 is located between the parts 12, 13 of a cross-over main, and contains a roll 26, dipping into a reservoir of tar. The gases pass from the scrubber to a settling chamber 27 provided with grids to recover tar particles carried over with the gases. The gases finally pass to condensers 14, 15, creosote oils being removed in the former, and by further cooling carbolic oils are removed in the latter. The heavy tar drawn from the collector mains may be used in the scrubber. The latter may be byepassed by a cross-over main 13<1>. Specifications 298,153, 303,166, 306,093, and 315,374, [all in Class 55 (ii), Gas manufacture &c.], are referred to.

Title: Resilient Coupling for Tubes.
IPC: F16L23/028
Filed: 1966-09-01
Abstract: 1,155,303. Pipe couplings. AUTOCLAVE ENGS. Inc. 1 Sept., 1966 [26 Nov., 1965], No. 39148/66. Heading F2G. In a resilient coupling for connecting tubes 5, 6 end to end and including flanges 10 positioned on the ends of the tubes, at least one of the flanges is movable axially along the tube on which the flange is positioned and there are opposed seats 8, 11 on the tube and the flange for holding therebetween a resilient tubular member 9 in the form of a toroid. A sealing member 7 is disposed between the opposed ends of the tubes and, together with the members 9, is compressed when the flanges are drawn towards each other as by screwed rods 12, the member being positioned relative to the end of tube so that the force exerted by the member opposing the force tending to compress the member acts along a line passing through the contact between the sealing member and the end of the tube on which the member 9 is positioned. As shown, the toroids comprising helical springs are seated in recesses 8 formed in thickened wall portions of the tubes 5, 6 welded to tubes 19, 20. At high temperatures, the springs are compressed to absorb the resulting expansion of the tubes, and, conversely, upon cooling of the tubes the springs expand to maintain a tight joint between the tubes and sealing member 7. The springs 9 may have a smaller helical spring or semi-circular rods inserted therein; instead of springs there may be used a continuous metal tube, segments of tubes or springs or C-shaped segments positioned side by side. In a modification, the thickened portions of the tubes 5, 6 are replaced by collars screwed on to the tubes 19, 20.
