Abstract

1,024,574. Purifying sea-water by freezing. DESALINATION PLANTS (DEVELOPERS OF ZARCHIN PROCESS) Ltd. Oct. 24, 1962 [May 16, 1962], No. 40285/62. Heading F4H. [Also in Division F1] In the plant for purifying sea water described in Specification 1,024,571, the rotary compressor for moving the vapour from the evaporation chamber to the condensation chamber comprises an impeller having main blades preceded by inducer blades 308, 310. Each blade 308 and an adjacent blade 310 are formed from a single strip of metal or fibreglassreinforced plastics material which is bent into a loop at its centre and inserted into a bore 302 in the inducer hub 300. The loop is then expanded into contact with the bore by means of a tapered tool. A bush 326 of the same diameter as the cylindrical head of the tool, is placed on top of the tool and forced into the loop in succession to the tool. A tool 334, Fig. 17 (not shown), is then inserted between the blades 308, 310 to spread them into contact with the walls of a slot extending between the bore 302 and the periphery of the hub 300. The blades are held in this position by a member 346 bolted to the bush 326. Flexible U-shaped members 364, 372 strengthen the blades and reduce vibration. Slots 390 may be provided in the bushes 326 to allow the bushes to be expanded by means of plugs threaded into the ends of the bushes, whereby the blades are locked in place. The main blades are of similar construction and fixing.
