Industrial Notes Two-Stage Oxygen Regulator T~hc Oxvs-eid Acetylene Co., 30 E a s t Fo.ty-second St., New York, ^C. Y., has added to t h e Prest-O-Weld line a two-stage oxygen regulator, type R-109, designed t o eliminate fluctuation in working oxygen pressures. The chief feature is two-stage pressure reduction, accomplished t-hrougîi the medium of two independent sets of diaphragms, valves, and springs. In the first stage t h e cylinder pressure is reduced through a non-adjustafc>le reducing valve to about 175 lbs, per SQ. in. Leaving the first stage» the oxygen passes to a. second valve and diaphragm assembly, where the pressure is red u c e d to t h a t desired, t h e second-stage reducing valve being adjustable by meatus of =a hand wheel. T h e regulator will operate with equal efficiency whether tbie oxygen cylinder is full or nearly empty, a n d the working pressure will remain constant.
Automatic Arc Welder T h e Lincoln Electric Co., Cleveland, Ohio, h a s developed the Lincoln a u t o m a t i c tractor-type arc welder, utilizing t h e "electric t o r n a d o " process to solve t i i e material-handling problem for manufacturers of large pipe.
