There is a cut-off valve at the top of the tank,which enables the burners to be cleaned without losing the airpressure. To braze readily a pressure of 40 lbs, is required. Theburners are provided with swinging joints, allowing the operator toraise or lower the flame if necessary while in operation. Thismachine is made especially for electric street railways, and is guar-anteed to give satisfactory results. An Injector Condenser. In the accompanying illustration is shown a condenser in whichis employed the combined action of an injector and syphon. It isthe invention of Henry W. Bulkley, by whom it has been manufac-tured for some years. In this condenser the condensing water entersat a side opening, and passes downward around the exhaust nozzle in a thin circular film. The exhauststeam is thus condensed within ahollow cone of falling water, whichby its velocity through the contract-ed neck of the condenser expels theair and vapor into the dischargepipe below. The column in thedischarge pipe being long enoughto overcome the pressure of the at-mosphere, the water is deliveredinto the hot well by gravity. Avery high vacuum is thus main-tained, and may be formed before
