Title: Multi-stage flash evaporation system
IPC: B01D3/06
Filed: 1962-07-27
Abstract: 973,519. Multi-stage flash evaporators. CHICAGO BRIDGE & IRON CO. July 27, 1962 [Sept. 1, 1961], No. 28893/62. Heading B1B. In a multi-stage flash evaporator comprising an elongated chamber 10 divided by partitions 11 into a plurality of stages, each at a successively lower pressure, and condenser tubes 13 which pass through the chamber via apertures 12 in the partitions, secondary partitions 27 or 37, are provided adjacent to the partitions 11 whereby confined spaces are formed between the primary and secondary partitions, and the non-condensible gases accumulating in one stage are passed into the confined space between two subsequent stages, so as to prevent any leakage of vapour from stage to stage. The liquid to be vaporized (e.g. heated sea water) enters the first stage 10a via conduit 17, channel 18 and the flared inlet 19. Flash evaporation occurs, and the residual liquid passes via opening 20 into the next stage 10b for further evaporation. The mixture of vapour and non- condensible gas obtained in stage 10a passes over the condenser tubes 13, the vapour condenses, and the condensate is collected by an inclined plate 23 and flows into trough 24. Trough 24 extends throughout chamber 10 to collect the condensate from each stage, the total condensate being removed from the chamber via conduit 26. The non-condensible gases formed in stage 10a flow via outlet 30, throttle valve 32 and pipe 28 into the space formed between stages 10b and 10c by partitions 11 and 27. These non-condensible gases from stage 10a, being at a higher pressure than the mixture of vapour and gases in stages 10b or 10c, pass through the apertures 12 and 38 in the partitions 11 and 27 respectively, thus preventing any vapour from stage 10b leaking into stage 10c. Any vapour drawn into the outlet 30 in stage 10a passes with the non- condensible gases into stages 10b and 10c in close proximity to the condenser tubes 13 and: is thus condensed. Similarly, non-condensible gases from stage 10b are piped to a similar confined space between stages 10c and 10d, and this sequence is repeated from stage to stage until the non-condensible gases are exhausted from stage 10f via conduit 16 which is connected to a vacuum pump. Condenser tubes 13 are supplied with cold fluid from pipe 8 via headbox 14, and the heated fluid leaves the nest of tubes via headbox 15 and pipe 9. The cooling fluid used may be the feed liquid.

Title: Improvements in or relating to couplings for rods, tubes, and the like
Inventor: BAKER REUBEN CARLTON
IPC: E21B23/06
Filed: 1951-12-13
Abstract: 718,976. Pipe and rod joints. BAKER OIL TOOLS, Inc. Dec. 13, 1951, No. 29215/51. Class 99 (1). A joint for pipes or rods particularly adapted for attaching the tubing string B, Fig. 2, of an oil well to the tubular member 10 of a well packing device comprises a screwthreaded coupling 23, 31 adapted to be connected by longitudinal non- rotary assembly of the parts and to be disconnected by unscrewing. The threads 23, 31 are left-handed so that the joints of the tubing string e.g. C<SP>1</SP>, C<SP>2</SP> having the usual right-hand threads are not disconnected. A spigot member 26, screwed into the tubing string sleeve 25, and adapted to engage in the socket member 10 and be sealed by packing rings 43, carries slidably thereon a sleeve 27 having a number of longitudinal slots 29 extending over the greater part of its length. The slotted end of the sleeve has threads 31 which in the unstressed condition of the sleeve engage the threads 23 of the socket. The threads 31 are of the buttress type so that, when the string B is stabbed into the socket, the sleeve is contracted as permitted by a tapered portion 33 of the spigot, and the latter moves inwards until stopped by coacting shoulders 41, 42, the sleeve segments then springing outwards to engage the thread 23. The string is then retracted to bring inclined shoulders 36, 37 on spigot and sleeve into contact. to maintain the screwthreads in engagement. Keys 45 project from the spigot into the slots 29 whereby the tubing string may be released by unscrewing. In a modification the sleeve 27a, Figs. 7, 8 has a single dividing slot 50 and a number of flutes 51 to give flexibility. An annular projection 54 engages a recess 53 in the sleeve when the latter is contracted..Projections 54, 56 expand the sleeve when the tubing string is retracted, a shoulder 57 preventing undue expansion of the sleeve and binding of the threads. A key 66 secured at one side of the slot 50 extends into a groove 67 of the spigot 26a. The joint is otherwise similar to that of Fig. 2 and operates in the same manner. In a modified form of the joint of Fig. 1 the spigot and sleeve have a number of buttress-shaped coacting annular projections.
