A MERCOID UNFAILING ADVANTAGE Whatever your control requirement* may bo, it is conceded that the switch in a control warranto first considers* lion, due to its functional character-' ietics. All Mercoid Controls are equipped exclusively with hermeti cally sealed mercury switches of special design and selected materials.' Mercoid mercury switches are known the world over for their dependable service. They are not affected by dust, dirt or corrosion; nor are they subiect to open arcing with its atten dant consequences of pitting, stick ing or oxidized contact surfaces, all of which, are likely to interfere with normal switch operation. That is why among other things, Mercoid Controls on tbo whole give you assurance of better control per formance and longer control life--a distinct and unfailing advantage-- the reason why they are also the diolce of America's leading engi neers for many important industrial applications. MEftCOJD CONTROLS ore available in a euritiy of types for sensitive control of Pressure, Temperature and Lever actuation. MERCOID Apf'ROvi;n co.v/viw..s THE MERCOID CORPORATION 4fOt (IlMONf AVfNUt . CHICAGO. ILIINO'S NAPE Starts Long-Range Educational Program National education committee has In Ita initial meeting established lha preliminary outline of what, it is hoped, will be s long-range project far the National Asaoelatloo of Power Engineers. ThJi program consists of fire separate projects as follows: 1. Records are to be made of round-table discussions on various phases of powerplani operation and maintenance. The men who will collaborate In these discus sions are the best operating engineers end representative manufacturers' engineers avaOnble In metropolitan New York area. These recordings will be on four 12-in. records with an approximate playing time of SO min. As many copies of meh re cordings as are necessary are to be made and they will be available to chapters desiring to use this project in their educa tional programs. There will be no charge . for the miterliL 2. Soand-ollde Alms ere to be made on various operations of power-plant pro cedure: Specific power-plant operations wiD be selected, for example, operation and'maintenance of all o!l-bamlng equip- ! menu Again, this material Is variable without charge to all NAPE chapters wish ing - to use It In ihelr local educational program. 8. Representative committee will be formed from outstanding manufacturers of spedfic power-plant equipment and ma terials, for example, there will be sections on turblnee, centrifugal pomps, water treatment. end steam boilers. Each section will release impartial monthly bulletins relative to operation and maintenance of particular types of equipment represented by the respective section. Sack releases wfll go direct to educational chairman of In dividual chapters. There will be no charge for this service. 4. A bulletin an questions and answers, covering ell phases of power-plant open* lion, will be released etch month. Ihia will etso go direct to educational chair men without charge. 5. Each state where NAPE chapters sre located will have a state coordinator of education who will In every way possible aid, facilitate end expedite the national education program. The program, at outlined above, will be offered to thoee chapters desirous of using (is services. A bulletin wtil alto be re leased listing most successful local educa tional plant now In use. so that a chapter without a definite plan may ehoose a pattern from those that trial hat proved most effective.

Timken bearings hold mo*ing pjits 'in proper alignment because jjjrir tapered construction carries both radial and thruJt loads and eliminates end play. Maximum sup* port is provided by (he line contact between rolls and races. With Timken bearings, friction Is negligible. Timken bearings sre manufactured to extreme accuracy, with amazingly smooth surfaces. They retain this frictiou-frcc preci sion because of their true rolling motioo and the Timken fine alloy steel of which they are made. To be sure of long-time, troublefree crankshaft performance, make sure the trade-mark "Timken" is on every bearing you use. Timken bearings are backed by 49 years of bearing research and develop ment. No other bearing can give you all the advantages of Timken bearings. The Timken Roller Bearing Company, Cantoa 6, Ohio.
