The first lo use power from this plant was the Pittsburgl< eduction Company which has a contract for 3,500 h. current is by means of static and rotary transformersconverted to a direct current at 160 volts. This conversionis in two parts; first in static transformers to a two-phase 664 ^1)^S\g/Acw* alternating current at 115 volts; second, in rotary convertersto a direct current at 160 volts. This company is engagedin the manufacture of pure aluminum from an oxide of themetal bv smelting it in retoits, the mass being melted andthe aluminum reiluced by means of an electric Carborundum Company takes 1,000 h. p. from tlie. WESTINGHOUSE ARMATURE. Niagara Power Company and this is received in a singlestatic transformer built by the General Electric Companywhich reduces the voltage from 2,200 to 250; a reactive coilis employed to control this from the maximum downto as low a voltage as 90. Carborundum is a silicate of carbon made by subjectingthe constituents to an intense heat in an electric furnace is filled about half full of salt, sawdust andglass sand and on this is laid a core of coke about 21 in. in diameter and 14 ft. long; contact is made at the ends bypacking the coke tightly about bunches of carbon rodswhich constitute the electric terminals. The furnace is thenfilled with salt, sawdust and sand. The current heats thecore to incandescence and after 24 hours the process is com-plete, the carborundum being removed in crjstals. This isbroken up, sorted to size and moulded with a bindingmaterial, into wheels, etc., for grinding and polishing. The Acetylene L
