Patent GB-941063-A (GB)
IPC: B01D3/06
Abstract: 941,063. Flash evaporators; distilling water. RICHARDSONS, WESTGARTH & CO. Ltd. Feb. 18, 1960 [Feb. 27, 1959], No. 6918/59. Heading B1B. The vapours given off from a liquid in a flash evaporator are used to heat two separate streams of liquid, viz. (1) the feed to the evaporator, e.g. sea water, and (2) another stream of liquid, e.g. the condensate of the steam from a turbine. As shown, the evaporator comprises four heaters 10 mounted over four flash chambers 12 with communicating passages 14. Tubes 20 and 22 convey two separate streams of liquid through the heaters. Tube 22 passes liquid to be evaporated to a heat-input vessel 26, which is heated by steam from a steamboiler 30, the feed liquid then passing successively through the flash chambers 12 by means of apertures 32 in partition walls 34. Flashed vapour enters heaters 10, and unevaporated liquid is partly blown to waste through pipe 40 while the bulk is re-circulated through tube 22 after fresh liquid has been added thereto from a pipe 42. The vapour gives up its heat to liquid passing through tubes 20 and 22, is condensed, and the condensate is extracted by a pump 46. Some of the condensate is mixed with condensate entering through a pipe 48, this latter condensate flowing from a condenser 50 employed to condense spent steam from a steam turbine 54. If the temperature of condensate from condenser 50 is low it may be preheated, before admixture with condensate withdrawn from heaters 10, by vapour from an extra flash chamber (not shown) integral with, or separate from, the chambers 12 and heaters 10. Preheating may be by indirect heat exchange as in heaters 10, or by direct contact using a spray nozzle to spray the condensate into the flashed vapour. The mixture of condensates is passed by tube 20 through the heaters 10 and is thereby heated to a temperature approximating to that of water in the boiler 30.

Inventor: WILLIAMS ANTHONY CAREY
IPC: E03F1/00
Filed: 1995-03-11
Abstract: An interceptor tank has a preliminary chamber which is fed by overspill water through an inlet pipe 2. When the water level reaches the top of an inlet 3 of a skim pipe 4 the water is discharged for treatment in a tank 5 and then leaves through an outlet pipe 6 leading into an overflow pipe 7. A bypass duct 8 interconnects the preliminary chamber 1 with the overflow pipe 7. At the upper end of the bypass duct 8 there is provided an adjustable weir 9 formed as a sleeve within the bypass duct 8. As shown an adjustable screw 10 can be operated by a handle 11 to raise or lower the weir 9 so as to modify the point at which water entering the preliminary chamber 1 can be discharged through the overflow pipe 7 under overload conditions where the skim pipe 4 is unable to pass all of the incoming water into the treatment tank 5. When the weir 9 is fully raised it will locate against a seal 12 to close off entry to the overflow pipe 7.

Filed: 1994-10-17
Abstract: In summary, the present invention provides a method and apparatus for determining an external power supply type and modifying the charging of the internal battery (14) based upon the external power supply type and battery information. The device has an external power adapter (12) used to provide power to the device (10), as well as charging current for the battery which is regulated by the internal battery charger. A microcontroller (20) in the device (10) regulates the charging current to the battery (14). The microcontroller (20) preferably contains an A/D converter (21) which is connected to a pull-up resistor (32) internal to the device, and to a pull-down resistor (34) in the external power adapter (12). The voltage generated by the resistor divider network including the pull-up resistor (32) and the pull-down resistor (34) in the external power adapter is used to identify the external power adapter type. By changing the value of the pull-down resistor (34) in the external power supply to identify the external power supply, the microcontroller (20) in the apparatus may determine the optimum charging profile to use for the battery based upon the charger type and other information relating to the battery. <IMAGE>
