To meet these severe service demands, Westinghouse offers a com* plete line of Type C General Purpose Turbines with "built-in protection" against overspeed . . . steam leakage . . . explosion . . . unbalance. Built-in protection is typical of the plus Westinghouse General Purpose Turbines ... that result in extra reliability, extra safety,' economy in operation.

Co., Box 868, Pittsburgh 3Q| HAL PROTECTION--Dazing normal operation the turbine speed is con* troQed by the centrifugal-weight gover.nor, or a regulator. If for any reason this control should fail, the overspesd trip defloe takes charge--simultaneously closfng the butterfly valve and the governor valve when speed reaches 10 pet cent above normal. SHAFT HOTECTtQN --to prevent team leakage and consequent oil con tamination resulting from rust-cut car bon gland segment^ shaft is sprayed with a generous thickness of high chrome-nicks! steel at the two gland sonee. Shaft is grooved, undercut and knurled to provide a permanent anchor for the sprayed metal. After spraying^ entire shaft is finish-ground.
