Title: Improvements in and relating to compression distillation plant
Inventor: BROWNHILL FRANK DENISON
IPC: B01D1/28
Filed: 1949-07-22
Abstract: <PICT:0669928/III/1> In distilling water using an evaporator of the vapour-compression type, the water is preheated to precipitate a considerable proportion of the scale-forming constituents, by contacting it with superheated steam, the steam being derived by submitting the condensate from the heating-coil of the evaporator to partial flash-vaporization; and the precipitated scale-forming constituents are separated from the heated water before it is introduced into the evaporator.  The flashed steam is preferably superheated by use of the waste heat of an I.C. engine, or a gas turbine, or a steam power-plant.  Sea-water is introduced through spray 3 into preheater 4 which is supplied with superheated steam through nozzles 5; and the precipitated sludge is blown-down by pump 7.  The hot brine from preheater 4 is passed through pipe 8 to evaporator 9, from which concentrated brine is withdrawn through pipe 13.  Steam is withdrawn from the top of the evaporator, compressed in axial-flow turbo-compressor 10, and passed through coil 11 which is immersed in the brine.  The greater part of the condensate formed inside coil 11 is passed through throttle-valve 15 into separator 16 where some of the condensate flashes into steam.  The water which collects in the bottom of the separator, is drawn-off by pump 18 to the distilled-water storage tank.  The steam withdrawn from the separator through pipe 19, is compressed in compressor 20; and is then superheated in superheater 21 by heat-exchange with exhaust gases or vapours (flowing through duct 22) from an I.C. engine or gas turbine.  That part of the condensate from coil 11 which is not introduced into the separator, is passed through by-pass 23, and is vaporized in heat-exchanger 25 which is heated by the exhaust gases leaving superheater 21; and the steam so formed then passes to superheater 21 where it mixes with that from separator 16.  The superheated steam withdrawn from the superheater, is introduced through nozzles 5 into preheater 4.  When operating in conjunction with steam powerplant, compressor 20 and superheater 21 may be replaced by a steam-ejector; the by-pass 23 and heat-exchanger 25 are then dispensed with.

Title: Improvements in or relating to form grinding and analogous machines
IPC: B24B19/12
Filed: 1944-10-13
Abstract: 584,760. Copying by milling and turning. JONES & SHIPMAN, Ltd., A. A., and CHAMBERLAIN, W. V. Oct. 13, 1944, No. 19771. [Class 83 (iii)] [Also in Group XXIII] In a machine for cutting cams &c. by grinding, polishing, turning or analogous machining operations the work is carried by a rotatable spindle in a holder movable relatively to the cutter by means of a pattern cam canied by a shaft rotatable at the same speed as the work, the abutment for the pattern cam consisting of a feed cam which is rotated intermittently to feed the work towards the cutter after each revolution of the work. In one form the work is carried by a collet 5 in a spindle 2 rotatably mounted in bearings 6 in a holder 1 which is pivoted at 16 on a fixed axis. The spindle 2 is rotated by a splined worm wheel 27 driven by a worm shaft 26 and an electric motor 24 on the fixed frame 10. A shaft 3 rotatable in the holder 1 is driven by gearing 28, 29 from the spindle 2 and carries the pattern cam 4 which rotates in contact with a roller 14 on a lever 12a pivoted on the frame 10 at 13. The feed cam 11 forms the abutment for the roller 14 and is carried by a shaft 9 rotatable in the frame 10 by a ratchet wheel 17 thereon, a pawl on a lever 19 and a link 21 connecting the lever to a crank 22 on a gear 23 driven by the gear 29. As the cam 4 rotates in contact with the roller 14 the holder 1 is rocked to move the work relatively to the stationary cutter to produce the shape of the cam 4 on the work and on each revolution of the spindle 2 the shaft 9 is given a part rotation to bring another portion of cam 11 against roller 14 to advance the work nearer the cutter. The feed of shaft 9 by the pawl may be varied by a shroud on the ratchet 17 whose adjustments are indicated by a graduated scale. When the shaft 9 has completed a revolution the roller 14 drops into a depression 11a in cam 11 and an arm 12b on the lever 12a then engages a switch 33 to stop the motor 24. The cams 4, 11 are held in contact with the roller 14 by a spring 15. If axial copying motion is also required a face cam 35 is attached by a ring nut 39 to the work spindle 2 to co-operate with abutments on a ring 37 secured to the holder 1. A spring 40 maintains the cam 35 in contact with the ring 37 and a spring 41 holds the worm wheel 27 against a thrust bearing 42 during axial movement of the spindle. The Provisional Specification states that the holder 1 may move in a straight line instead of being pivoted and the action of the spring 15 may be replaced by gravity.
