Dem of ring construction Trap was made of a lQ-in.-long sec tion of 2-in. pipe filled with 2 to % In. reducera at each end. Reducer. &t the Grooved Bing Stops ' Oil Leakage Along Shaft When oeaiuncs are lubricated under pressure it sometimes proves difficult to atop oil leoking out along the shaft. Cotton ot felt packing usually proves ineffective. A ring with grooves running contrary to direction of shaft rotation, mounted as shown, will stop all leakage while the shaft turns. This has proved effective even with vibrating shafts. The ring sketched has aerew-shaped threads with a double pitch. These grooves cause oil backflow that stops leakage. D WlJSMAN Stirtmtme, Dutch Cuiona bottom carried a petcock for cleanout purposes, while the upper reducer was equipped with two side inlets, also pipe site. The top tap from line piessuie carries the lead down to about midway o( the body. The aide tops lead to the instruments and control de vices. Temperature changes and occasional bleeding of the instrument lines caused slight condensation in the trap. Collec tion was slow but enough to affect In strument accuracy eventually. Rust and hydrate crystals, collected during the winter, were periodically removed by blowing down through the petcock at the bottom. Elton Stmurtt Houston, Tex. (795) Stop for a moment and consider your boiler plant. Can you, as a power plant engineer, honestly give your plant an OK /or completely successful operation ... especially its water conditioning? Efficient water conditioning starts with the row water supply and continues through the plant, taking in many problems. Correct water conditioning is a matter of careful and scientific control. W. II. & L. D. BETZ is on organisation of engineers and chemists specialising in the solution of all industrial water problems. Years of experience have made Beta woter conditioning service scientifically correct... complete ... economical. Our nationwide staff of engineers will welcome the opportunity of discussing with you this important subject of water conditioning . . . W. H. & L. D.
