Filed: 1925-02-27
Abstract: 251,722. Clark & Co., Ltd., T. &. C., Iles, C. H., and Perry., P. J. Feb. 27, 1925. Centrifugal machines; feeding.-For distributing cement in powdered form within a rotating pipe mould, an outer tube m is arranged to rotate on a fixed tube l. As the spinning mould a advances, pegs s on a sliding sleeve engage guides t on the mould, the continual movement of the mould then sliding the sleeve axially without rotation. A pin on the sleeve co-operates with a helical slot r on the outer tube m to rotate the latter during the process, and thus bring successive portions of this slot into register with a longitudinal gauze-covered slot, on the underside of the fixed tube, thus allowing the powder to escape from the interior of the fixed tube progressively. A final hand feed of the carriage is necessary to complete the distribution over the far end of the pipe. A charging slot on the upper side of the fixed tube registers with the slot r in one position of the apparatus. The tube m may be rotated by hand instead of automatically. The distributing-apparatus is pivoted at h and counterweighted at j so that it can be swung up out of the way to allow the completed tube to be withdrawn from the mould. Strips v may be used to strengthen the metal tube. A mechanical vibrator l<1> also may be employed to prevent sticking of the powder.

Title: Machine for generating rotors for elastic fluid mechanism
IPC: B23C3/18
Filed: 1944-03-27
Abstract: 635,752. Generating turbine-blades. TURBO ENGINEERING CORPORATION. March 27, 1944, No. 5649. Convention date, March 26, 1943. [Class 83 (iii)] [Also in Group XXVI] In a machine for generating the vanes of elastic fluid turbine or impeller rotors, a formed milling cutter is fed in directions along and perpendicular to its axis, whilst the work is rotated about an axis which is parallel to the plane of movement of the cutter. In one form of machine the work W, Fig. 1, is adjustable parallel to guides 40 on a table 38 adjustable on guides 36 provided on a saddle 4 which can pivot about a vertical axis 6 adjustable transversely to the cutter 64. An arm 8 on the saddle 4 has a slot 10 perpendicular to the guides 36 in which slides a cross-head 12 pivoted at 14 to an arm 18 pivoted at 20 to a carriage 22 movable parallel to the cutter axis by a nut 26 thereon and a rotatable screw 28. The cutter-head 60, carrying an electric motor for driving the cutter spindle, is fed vertically on a pillar 42 by a nut and screw 56 and the pillar is fed along horizontal guides 41 by a nut and screw 46. The screws 28, 56, 46 are all driven at synchronized speeds from a main shaft 30 through pick-off change wheels. In operation, vanes of the shape shown in Figs. 12 and 13 are generated in a solid forging by the cutter 64 whilst the latter is fed vertically and axially and the work is swung about axis 6 by movement of the carriage 22. Stops 24, 241 on the carriage locate the arm 18 in positions for generating right and left-handed rotors and the pivot 14 is adjustable along the arm 18 to vary the curvature of the vanes. In a modified machine without so many adjustments the' work W, Fig. 10, is mounted on a holder movable about a horizontal axis 70 by an arm 72 having a slot 74 for a cross-head 76 pivoted at 78 to a block 80 movable along horizontal guides 84 by a screw 82. The cutter 106 is carried by a head 102 fed axially by a screw 118 on a saddle 98 which is fed horizontally on guides 93 by a screw 96. The generating movements are the same as in Fig. 1, but adjustment of the pivoting motion of the arm 72 is obtained by change gearing for the screw 82 instead of by altering the pivot 78 of the cross-head. A compound rotor having separate stages may be produced by moving the work axially to bring the respective stages adjacent the cutter. The Specification discusses mathematically the shape of vanes generated. Milling-cutters.-The cutter 64 or 106 is of tapered form, preferably hyperboloidal in profile, the sections of different diameter being operative at different portions of the vanes on the work. Alternatively the cutter profile may be made up of circular arcs or straight lines, and differently shaped cutters may be used in succession to generate respective parts of the vanes.

Title: Production of uranium halides
IPC: C01G43/04
Filed: 1943-04-09
Abstract: Uranium halides, particularly the tetra- and hexafluorides, are made by the interaction of a gaseous hydrogen halide and uranium dioxide at elevated temperature, the dioxide being maintained in fluidized suspension in the hydrogen halide.  Thus uranium tetrafluoride is made in this way from uranium dioxide and gaseous hydrogen fluoride.  The dioxide may be made by reducing U3O8 in fluidized suspension in hydrogen and the resulting fluidized suspension of dioxide may be treated with hydrogen fluoride, or the reduction and fluorination may proceed together.  The tetrafluoride may be converted to hexafluoride by treatment with fluorine.  The process may be carried out in a continuous manner or batch-wise.
