Straws Point Way In Power-Supply Situation Recent developments in the powersupply situation in different porta-of the country reveal the nature of the problem and tome of the meant taken to solve ft. fn this they are tike straws that point the way the wind blows. Working-Hour Shift. In St. Louis, delegates to the AFL Central Trades and Labor Union meeting approved a shift in working hours as o meant of avoiding curtailment of industrial op erations or a complete shutdown of some plants because of the tight power situation in the areo served by the Union Electric Co of Mo. John ] Rollings, executive secreiary of the group, stated that together with a CIO representative, he had conferred with. Unfon Electric officials and wes advised that unless the compony'e pres ent power-conservation campaign is successful, Sc Louis and vicinity may faeo a critical situation. Discussions covered the possibility of shifting to off-peak houre Industrial operations in volving large usage of electricity. While such o shift would interfere with social and economic life of the workers. Roll ings expressed the view that this step would be preferable to complete shut down or the laying-off of industriol workers if the situation worsens. Delegates approved the Rollings re port, which also recommended that AFL unions discuss thoroughly with (heir employers a shift In operating hours if requested to do so, in the event that the present voluntary electricity con servation program of Union Electric proves unsuccessful. Cooperation in the conservation program was also recom mended. Navy Aids Maine. To reduce power shortage in Aroostook County, Maine, the U. S. Navy ordered, in November, the fitting out of two destroyer-escorts, the Afaloy and the Foss, for usa os auxiliary sources of electricity. With suitablo transformer equipment, the 3600-lnv power plonts of these vessels can feed Into the Central Maine Power system for transmission to the Medway, Ifoulton and Presque file area by way MYSTIC'S THIRD UNIT ON LINE: Boeton Edison Co'o Mystic generating t lion at Everett, Maes* reached 160,000-kw capacity on Oct 81, 1947 wheati third 60,000-kw General Electric turbine (background, above) went Into cents All three machines operate condenetng, eteam being supplied by Combuctlenti gingering Co bollere working at 1400-pel drum preceure and 910 P, Contln expansion will bring Doeton Edison Co'e total capacity to 690,000 kw this ye of the Bangor Hydroelectric Company. Drought conditions hit Maine Public Service Co, Presque Isle, so hard that it was forced to divide its system in two ports, rationing service to each on a 2-hr "on" and 2-hr "off" basis. With the potato crop being processed, a con siderable loss threatened. N. Y. Picture Better.

Here's a convenient check list for proper trap selection:* 1 DOES TIIB TRAP HAVE ADEQUATE CAPACITY FOR PEAK LOADS? Traps should hsv the rapacity to take rare the abova normal condemate load* encouatercd In Mining up cola equipment. This will often uve hour* of wsrailng-up tune ana greatly increase production. 2. DOES THE TRAP ACTUALLY HAVE THE CAPACITY CLAIMED FOR IT? It is possible to unknowingly buy a trap with imuffirient capacity. This limit* production and wastes fuel, Armstrong trap rapaclrlei are very centsetratlrelf baled on text* with hot condensate, and a liberal safety factor is recom mended. If you follow Armstrong, recommendation* the trip* will handle any condensate load that will be encountered. j. IS THE TRAP SUITABLE FOR THE PRESSURE? A trap won't work satisfactorily at a steam pressure above that for which it is designed. (In switching trap* from one location to another, be sure they are not put on a fine with s pressure above their rating.) 4. DOES THE TRAP HAVE ADEQUATE AIR-HANDUNC CAPACITY? Air (always present in straw) reduces hrat transfer efficiency, lowers temperatures and alow* up production. Armstrong traps discharge ail normal amounts of air along with condemate. J. DOES THE BODY STYLE PERMIT THE MOST EFFI CIENT INSTALLATION? Correct installation, essential to efficient trap performance, is simplified and reduced in cost by the choice of Armstrong trap body styles: No. 800 Series side Inlet--side out let; No. 801 Series tide inlet--bottom outlet, and No. 200 Series bottom inlet--top outlet. *Th* St-pise ARMSTRONG $T6AM TRAP BOOK rM complete 4m On irtp Mienion ind Icituliitlon on >11 clsiie* of equipment.
