| JOINTING APPLICATIONS. Amongst jointing applications in which the PATENT PRESSURE FILLED JOINT RING is being successfully used are the following:— DIESEL CYLINDER HEADS and OIL COOLED PISTON HEADS. DIESEL FUEL and EXHAUST VALVES. OIL ENGINE VAPOURISER HEADS. STEAM ENGINE, BOILER, SUPER HEATER, ECONOMISER and PIPE JOINTS. WATER MAINS, INSPECTION COVERS and FLANGE JOINTS. WATER, OIL, MILK, and LIQUID FOOD PUMPS, and PIPE LINES, with pressures ranging up to 3½ tons per square inch. LIQUOR HEATING and COOLING PLANTS. AMMONIA and CHEMICAL PLANTS. HYDRAULIC and AIR PRESSURE LINES. HOT OIL CIRCULATING PIPE LINES, ETC., ETC. A FEW REPRESENTATIVE USERS. MESSRS. PETTERS, LTD. MESSRS. RICHARDSONS, WESTGARTH & CO., LTD. MESSRS.

" WILLS " Patent Renewable Seat Wheel Valves are of orthodox design, except that the sealing member is composed of a " WILLS " PRESSURE FILLED JOINT RING (Patent No. 380853). The ring is of tubular construction, hermetically sealed and containing gas under pressure. This gives a resilient cushioning effect between the upper and lower seat members, and being of metal is practically indestructible. These Valves can be used as Regulating Valves in a partially open position indefinitely without detriment. 11 | ||
