More PRACTICAL IDEAS. All Toped Up i came ACROSS an electrician all decked out in friction tape, iketch. Tape around ahlrt aleevca and coverall legi kept them away from wiring. Tape .wound around plier handles kept him from getting a blood blister when he "micaed" with this implement. Tape around screwdriver handle not only helped insulate, but also protected hand grip and gave firmer hold. D B Clapp Newark, N.J. Emergency-Equipment Display Ready for Trouble] We have emergency-equipment centers at various places in our plants. This photo shows the one In main hallway of building No. 2. Each center Is aloag a welt-traveled place so employes pass the center often and know exactly where to go in case of trouble. With fire extinguishere for various-type fires (all labeled beildi stretcher, fire ax, etc, we are ready action at all limes. Employes are to conscious of ifcmf equipment that they instinctively go the right place every time that an erne- gency arises. G Hocc Philadelphia, Pa. Return r ttwope Fuel-Oil Bypass Solves Problem Burninc oil in one of our 550,000.]l>per-hour high-pressure boilers gave* us e problem. Things ran smoothly while carrying full load. Trouble came when we dropped load to what we celled the critical load during the night. It's criti cal because one fuel pump isn't enough and two pumps were more thon enough. We can overcome this by opening re circulating valve, but then fuel oil won't register on meter correctly. I checked the fuel-oil lines, noticed a free drain-connection on fuel-oil header before the meter. Also a free* drain connection on return line. I tied them together with %-in. piping and a valve as shown. This works well during critical load. It now serves two purposes. Excess pressure is relieved during low toads, and return line going bock to atorage tank it kept warm In winter when it would freeze. Then hours would be spent getting it warm enough to ihow and to flaw freely again. F A Tuiiaho Jeraey City, N. /. Removing Tight Nut Nuts fitted in a recess are usuolly removed by.a box spanner. If nut is very light, you might have to apply heat to expand nut. First, place spanner over the nut. Then place a layer of boiler lagging over top of nut. Ploy e blowpipe flame down the center of the spanner. Boiler lagging protects top of nut from direct healing and deflects heal to wails of spanner. This heats sides of nut, causing it tn expand and loosen. W E Wanner IFoodford Green, Eng.

RIANT ORIRAIION AND MAINTENANCE SECTION fOWPj new WIDER VISION for easier remote boiler water level readings Vastly improved visibility of remote boiler water level readings can now be enjoyed by boiler plant.operators. A new "wide vision" face on Yarway Remote Liquid Level Indicators allows reading from the side as well aa front of the indicator. Boiler water levels and other liquid levels can be checked from most any position. Indicating mechanism is operated by the boiler water level itself--assuring instant, accurate readings. Yarway Indicators are of the manometric type with automatic temperature compensation, as approved for use under the recent A.S.M.E. Boiler Code Com* mittee ruling in Cose # 1155. Over 10,000 are used throughout in dustry for boiler'water and other liquid level indication . !. and for superheater pressure differential indication aboard ship.
