Return to Top> What is a Stationary engineer? It's not a term I've come across in the > UK civils industry. Save, perhaps, to describe an engineer having a nap > in a slow afternoon :) They pay me for what I know, not so much what I do. "Stationary" is the operative word (grin). > -- > Shaun Lewis, The Dredging and > Assistant Estimator Construction Company Ltd. A Stationary Engineer is a licenced trade, and is *usually* in charge of the boiler room, and associated equipment (refrigeration, ventilation, steam generation and use). The majority are involved in anything from medium to heavy industries (i.e. from small fire-tube boilers in manufacturing plants, to 1000 MW generating stations). In Ontario, Canada (and the rest of the provences, I believe), every plant must have a Chief Engineer, who would normally supervise the Shift Engineers, maintenance staff, and many engineering projects (hence the business cards). A boiler room is quite often called the "power plant", so sometimes Stationary Engineers are called "Power Engineers" (the trade is actually called Power Engineering, the tradesmen Stationary Engineers). When the steam locomotive had its day, the person in charge of the boiler and engine was called a "locomotive engineer" or "steam engineer". People who ran nearly identical equipment (boilers and steam engines), whose machinery was firmly affixed to the ground, were called "Stationary Engineers" (our boilers don't go anywhere (grin)). Same equipment on ships, "Marine Engineers". A while back we did have a bit of a dust-up over the use of the term "Engineer". I guess the Society of Professional Engineers felt they had the exclusive rights to the name "Engineer". But it seems "Power Engineers" were around and using the name long, long, before any "Professional Engineers" showed up (grin). So now (and please, anybody correct me if I am wrong, it's happened more than once) only those recognized by the Society, and Power Engineers, are allowed to use the term. Now that everybody knows more about Stationary Engineers than they ever wanted to know, I hope that answers the rest of the questions in the other posts. K. Jones Kjones@interlynx.net

FREE! HELICAL COMPRESSION SPRING PROBLEM SOLVE ============================================== K.I.T.A.L. Software offers a one time free solution to your most urgent or chalenging HELICAL COMPRESSION SPRING design problem. To give you the best solution for your problem we will appreciate if you can define your problem in the following manner. 1. MAXIMUM OUTSIDE DIAMETER 2. MAXIMUM WORKING LENGTH at first working point (for example: if you design a check valve and the maximum space that is left for the spring is 2 inch long and 1.05 inch inside diameter, then the maximum working length at first working point is 2 inch and the Maximum outside diameter is 1 inch . When it is possible you will receive solutions of smaller springs too) 3. Spring FORCE at first working point 4. Spring EXTRA DEFLECTION (from the first working point to the second load point) 5. Spring RATE (the force at the FIRST LOAD POINT divided by the force at the SECOND LOAD POINT) 6. Type of use (STATIC or DYNAMIC) 7. MINIMUM INSIDE DIAMETER (If necessary, it limits the wire diameter size) 8. Preferred wire MATERIAL (see preferred list) 9. Maximum SOLID LENGTH (when the coils touch each other), optional. When it is possible you will receive more than one solution. Please send your problem description before the end of January 1997 by E-Mail to: tsiporak@actcom.co.il If you prefer to send blueprints you can mail it to: K.I.T.A.L. Software P.O. Box 748 Karmiel, 20100 ISRAEL To receive an answer you must forward an E-Mail address. PREFERRED LIST OF WIRE MATERIALS ================================ 1. MUSIC WIRE (ASTM A228) 2.
