Filed: 1925-12-02
Abstract: 244,099. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Allen, R. C.). Dec. 3, 1924, [Convention date]. Turbines.-Long tapered turbine blades 16, 17 are given a constant leaving angle @and an inlet angle a increasing from root to tip, and one blade surface comprises a cylindrical surface 46, while the other blade surface comprises a cylindrical surface 49 supplemented by a flat, tangential surface 51. The two cylindrical or otherwise curved surfaces 45, 49 have axes which pass through points X, O and diverge from the tip to the root of the blade both across the width and across the thickness. Surfaces with intersecting axes may be used. The inlet edge of the blade is a plane curve, while the outlet edge is straight. Fig. 4 shows a milling-machine with a belt driven cutter 31 at work on a block 29 for forming the intaglio member of the die block with which the blades are to be forged. The bearings 32, 33 for the cutter are moved to and fro in guides 34, 36 by gears 37, 38 and feed screws 39, 40 actuated by a hand-wheel 43. The block 29 is placed at rightangles to the cutter 31 and a cut having a contour 45, 46 is made straight through the face of the blade along the line 44, Fig. 5. The surfaces 45, 46 define the contour of the cameo member of the die block. In the next operation a milling-cutter makes a cut in the block 29 having a contour 49, 51, the block in this case being raised at one end 53, Fig. 8, and also set at an angle to the position shown in Fig. 4. Spaces 56 are provided to accommodate flow of metal in the forging operation. The cameo member has a constant cross-sectional area. Alternatively, this area may be variable, while the area defined by the surface of the intaglio member may be of constant cross-section. Instead of milling, other processes such as planing may be used. Each blade may be machined individually instead of using a die block.

Title: Improvements in or relating to gas separation
IPC: F25J5/00
Filed: 1961-08-24
Abstract: 979,422. Gas separation. UNION CARBIDE CORPORATION. Aug. 24, 1961 [Aug. 26, 1960; Dec. I, 1960; Dec. 2, 1960 (2)], No. 30491/61. Heading B1L. Oxygen-nitrogen gas mixtures are separated by contacting the gas mixture at 0 ‹C. to - 150 ‹C. with a bed of crystalline zeolitic molecular sieve material which has been ion exchanged so that it has as at least one of its cation constituents lithium, strontium, barium, nickel, rubidium or calcium, the bed having effective pore sizes of at least 4 Angstroms after cation exchange, thereby adsorbing nitrogen from the mixture, and discharging an oxygen enriched product gas from such bed. Preferably, the zeolitic molecular sieve materials are cation exchanged zeolite A or X and others mentioned are zeolites D, R, T, Y, L and chabazite. As in Fig. 1, oxygen-nitrogen containing feed gas, e.g. air, is supplied via conduit 10, directed through compressor 12 to heat exchanger 14, attaining a temperature of 10- 40 ‹C. Moisture is removed by passing via conduit 18 and either of valves 20 to driers 22 arranged in parallel, which are regenerated by hot air. The dried feed gas is discharged via either of valves 34, to heat exchanger 38, through control valve 42 to recuperator 44 or 86 previously cooled by passage of cold nitrogen desorbate gas. The emerging gas stream passes through conduit 45 to heat exchanger 46 for further cooling prior to adsorption in adsorber 62, said adsorber initially being at a lower pressure than the feed gas due to the previous desorption stroke. The warmed refrigerant emerging from the upper end of passageway 48 passes through conduits 50 or 52 to refrigerator 54 before being recycled through conduit 56 and 58. During adsorption, compressor 64 is used when atmospheric pressure is reached and at a predetermined value, e.g. 26 p.s.i.c., discharge valve 66 releases oxygen product gas at about -30 ‹C. into pipe 68, through valve 70 to feed cooler 14 to recover refrigeration before passing to gas holder 74 and compressor 76 for delivery at 93% purity. When adsorber 62 is on the adsorption stroke, second adsorber 80 is being regenerated by vacuum pump 94 so as to be ready for a further adsorption stroke. Fig. 2 (not shown) illustrates the use of a single heat exchanger in place of exchangers 46 and 100. Fig. 3 (not shown) also illustrates the use of a single heat exchanger, but employs three adsorption chambers respectively employed at any given time for adsorption, regeneration and repressurization for adsorption. In the apparatus of Fig. 4 (not shown) is arranged such that an [the] alternative drying system is employed and the recuperators (as in Fig. 1) are omitted. Preferably nitrogen adsorption is carried out in the temperature range -30‹C. to -50‹C. Specifications 777,232, 777,233, 841,812, 868,846, 909,264, 909,266, 912,936 and 972,831 are referred to.
