摘要： The process involves the steps of:spraying droplets of an aqueous alcohol input solution through spray-bars into a heat transfer fluid contained within a refrigerated process vessel and allowing the droplets to fall through the heat transfer fluid so that some of the water separates out as ice in the droplets;collecting the droplets as a slurry of ice and concentrated solution at the bottom of the process vessel andsubsequently removing the ice to produce a concentrated output solution from the process.The process can be repeated in subsequent process stages up to a limiting concentration of 92% by weight of alcohol in the case of ethanol. The invention includes apparatus in which the process can be performed. Means by which the efficiency of the process may be optimized are also included.

摘要： Multiple hole drilling by the electro-chemical process, in which individual jets of electrolyte impinge upon a workpiece, presents problems in assessment of hole depth reached and/or of jet deflection through jet orifice blockage. The invention provides a device which looks for the corona at the head of each jet. If the corona is present, the device generates and electrical signal which inhibits the actuation of a further device the function of which is to remove the jet, the corona of which has extinguished. Device also senses the displacement of the corona from a datum and in response, initiates switch off the machine tool.
