Title: Plastic extruder with evaporative cooling system
IPC: B29C48/03
Filed: 1954-11-12
Abstract: 761,953. Pug-mills. EGAN & CO., F. W. Nov. 12, 1954 [Aug. 18, 1954], No. 32882/54. Class 86 [Also in Group V] A horizontal extrusion cylinder, having a screw or the like rotating therein to force heat-softened material therethrough, is provided with cooling means comprising (a) a conduit for maintaining in direct contact with the cylinder wall a heattransferring liquid, e.g. water for temperature below 375F. and "Dowtherm" (Registered Trade Mark) for higher temperatures; (b) a condenser connected to said conduit to receive the vapours produced by the vaporization of the liquid; and (c) a pipe for returning the condensate from the condenser to the conduit. A screw cylinder A is electrically heated by bands 27 and is cooled by liquid which stands in circumferential grooves 1 joined by two longitudinal grooves 2, 3. Groove 2 communicates by a pipe 11 with a condenser comprising tubes 6 and 7 between which cooling water is fed by a solenoid - operated valve 21, the water entering by pipe 20 andleaving by pipe 22. In operation, liquid is filled into the grooves 2 and 3 until the level is at the midpoint of the upper groove 2, and the plastic is extruded. If the temperature in the extrusion cylinder exceeds, say, 350F., the liquid in the grooves will be vaporized and the heated vapour will rise through pipe 11 where it will be condensed (the heat being transferred to the cold water in jacket 6, 7) and the condensed liquid will pass via pipe 25 to the lower groove 3. The liquid may be water at temperatures up to 375F., at which the vapour pressure of the water is about 200 p.s.i., or "Dowtherm" at temperatures from 300 to 750F., at which the vapour pressure thereof is, say, 100-150 p.s.i. A vent valve 16, safety head 18 and pressure gauge 17 are connected to the condenser. Before operation, uncondensible gases and vapours are removed from the condenser by opening valve 16. The temperature of the heater bands 27 and the opening and closing of the valve 21 may be automatically controlled by means of a thermocouple 26 set in the extrusion cylinder wall, the thermocouple acting through a controller (not shown). The valve 21 may be controlled by hand. It is stated that the temperature might be controlled by the vapour pressure.

Title: Improvements in and relating to governing mechanism
IPC: F01D17/00
Filed: 1920-12-02
Abstract: 176,477. British Thomson - Houston Co., Ltd., (General Electric Co.). Dec. 2, 1920. Fluid governors.-A fluid governor for turbines &c. comprises a cylinder 20 and a piston 21 pressed downwards by a spring 26 and upwards by pressure liquid supplied through a pipe 27 from the lubricating oil circuit or other constantpressure supply. The liquid is drawn off from the cylinder partly by a pump 33 driven by the turbine &c. and partly by a pipe 32 provided with a regulating valve 37, the pressure on the piston depending on the speed of the pump and the position of the valve. The liquid escapes from the cylinder 20 also through a port 45 in the piston controlled by an adjustable valve 46. If the speed of the turbine increases, the pump 33 draws the liquid off more quickly and the spring 26 depresses the piston, which is connected to the valve-adjusting spindle 9 through a servo-motor 14 and rack and pinion 11, 10. If the speed diminishes the fluid pressure on the piston increases and the piston moves up and tends to open the valves. As the piston moves up or down, the port 45 increases or diminishes and allows more or less liquid to escape, thus tending to balance the effect of the pump 33 and prevent hunting. The servo-motor has a follow-up device and may be replaced by other transmission means. If the pressure under the piston 21 fails, the piston is forced down by the spring sufficiently to close the valves of the turbine through the servomotor.
