Abstract: <PICT:1116929/C1/1> <PICT:1116929/C1/2> In an apparatus for forming glass fibres there is provided a hollow rotor 501 (Fig. 5), having a peripheral wall 541 provided with a plurality of orifices 581 through which molten glass, fed to the inside of the rotor, issues in streams 581, the rotor having means 64 (Fig. 2) for rotatably supporting it around a vertical axis 461 and the peripheral wall 541 of the rotor is angled outwardly and upwardly at from 1 to 10 degrees with respect to the axis of rotation of the rotor.  Molten glass is fed from a foreheart 10 (Fig. 2) through a platinum-rhodium alloy tube into a bushing 681 (also platinum-rhodium alloy) at the bottom of refractory units 321.  The bushing 681 which is circular is electrically heated and contains a plurality of nozzles 741 through which streams of molten glass are fed on to the rotor walls, the rotor 501 being directly under the bushing 681, with the axle 461 passing through the bushing and unit 321 to the motor 64.  From an annular box 132, having orifices 148 equal in number to the nozzles 741, positioned at different levels around the periphery of the box, may issue combusted or combustible gas which serve both to control the glass temperature and also to distribute the molten glass evenly around the rotor walls.  The streams of glass 581 issuing from the rotor are attenuated into fibres by a strong gaseous blast from blower nozzles 901.  The fibres, which may be coated during attenuation, are collected in a special area on a conveyer belt from where they are removed for any further treatment, usually in the form of a fibrous mat.  A plurality of forming stations 30 are provided on either side of and along the length of the forehearth 10, the molten glass being fed through passages 80 and 82 or 821 to each bushing 681.  Flow of glass to each rotor may be stopped by passing cooling fluid in a tube round the passage 80. Figs. 9 and 14 (not shown) illustrate alternative arrangements of forehearth construction.  In alternative embodiments the burner used to heat the glass inside the rotor is fed by a tube passing through a jacket encasing the rotor spindle, the spindle having separate cooling arrangements.

Title: Improvements in evaporator systems
IPC: B01D1/26
Filed: 1920-08-20
Abstract: 158,221. Griscom-Russell Co., (Assignees of Brown, S.). Jan. 26, 1920, [Convention date]. Water, distilling; multiple-effect apparatus; bulk evaporators. - In evaporating systems, particularly those for distilling make-up feed-water for steam-engine plants, a portion of the residue is evaporated by its own heat and the vapour used for pre-heating the feed-water for the evaporating plant. The Figure shows a doubleeffect steam-heated evaporator of ordinary type. The residue leaves the second effect 2 at a pressure above that of the atmosphere and a temperature above the normal boiling-point, and passes by a pipe 9 to a trap 11 whence the steam generated by the reduction of the pressure passes by a pipe 15 to the pipe 12 by which exhaust steam is supplied to the feed-heater 13. When the pressure of the water leaving the effect 2 is not much above that of the atmosphere the trap 11 may be dispensed with, the pipes 9 and 12 being directly connected and the waste liquid escaping through a U-pipe long enough to prevent the escape of steam.
