The whole of these materials can he readily used in the simple style of construction involved. They de not require extensive inspection or maintenance. There are no frie tional parts, and hence no OCCA- sign for lubrication. The compress ed air discharges its function without churning up the liquid with the production of froth. Re- latively small pressures are quired, and air for the purpose can be taken from any available supply In these later applications the principle which has already been applied to comparatively harmless water is applicable to the most corrosive liquids,,
