spring . POWERFAX PCWERFAX A magazine of information for engineers and operators of steam and electric power plants, devoted mostly to the field covered by power equipment as manufactured by Elliott Company and its associates. The Lagonda Manufacturing Company, and Liberty Manufacturing Company. The picture on the front cover shows a night view of Pittsburgh's Golden Triangle with its sky scrapers and bridges illuminated for the celebration of Light's Golden Jubilee during the week of October 21, 1931, in commem oration of the 50th Anniversary of the incandescent lamp, invented by Thomas A. Edison. The Gold en Triangle, bounded by the Alle gheny and Monongahela Rivers, where they unite to form the Ohio, derives its name from the con centration of industrial and finan cial resources within its borders, but during this celebration.it was literally transformed into a golden fairyland by the liberal use of flood lights and festoons of in candescent lamps. The Liberty Bridge, shown prominently in the foreground, connects downtown Pittsburgh, via the Boulevard of the Allies, with the fashionable South Hills residential districts. The picture is a tribute to the electrical industry and the im portance of light in our modem civilization. NEW PUBLICATIONS Bulletin A-6. Twin Strainers.

INTELLECT IRRITATORS Well, we didn't hear from so many solvers of the little puzzles .printed in our last issue. Maybe they were too easy. Of course we don't ask anybody to send us his solutions. The prob lems are submitted simply for the enjoyment of those readers .to whom such things appeal. We of fer no prizes, but we are always glad to hear from those interested. Remember the problem where we asked you to make' six four-letter words out of the letters of the alphabet* using no letter more than one time? It was re ported that a professor who had given it in his classes in high school had found no one to supply1 a solution. But it isn't 90 tough. There are probably innumerable solutions. We list several of those on file: Vest Jynx Whip Olad Buck From Vest Lynx Whip Jamb Duck Frog Verb Lynx Whig Jump Sock Daft Crag Styx Whiz Jump Knob Fled Fact Jerk Whiz Jump Dogs Lynx All of these solutions leave out the tetter Q, and the other letter omitted is V or Z. Thos. H. Gleave, Chief Engineer of American Licorice Co., Chicago, in solv ing all the problems in the last issue, gave three solutions of the alphabet problem. The December issue had hardly been out before our friend A. G. Rosenbaum, Chief Engineer of the Louisville Gas and Electric Company came in with solutions of an three problems. Oh, yes, we've heard of some folks who bad trouble with the little rhyme with the blank spaces to be filled in with five words composed of the same four letters in different sequence. For the benefit of those: A vile old lady on evil bent Put on her veil and away she went. "Levi, my son," she was heard to say, "What shall we do to live today?'* The following problem was given us by Mr. J. N. Eley, Consulting Engineer, of Atlanta, Ga. Given plan and front eleva tions as shown, draw the side elevation. n PLAN XL FRONT ? SJDB In trying this problem out on one of our draftsmen, who incidentally solved it- in a Uttie different manner than the originator, he became so interested in this sort of problem that he find us up with a parallel problem involving differ ent shapes, as follows: PLAN i____r u----- u FRONT .? SIDE Try your hand at them. And now, the following problem is sub mitted by Mr. Ford W. Karris, Attorneyat-law of Los Angeles, California: A pole 100 ft- high is standing in water 10 ft. deep. It breaks and the upper por tion falls, but the two portions still hold together and what was formerly the top of the pole hits the bottom of the water, forming a triangle. The distance across the water from the vertical part still standing and the slanting broken portion, or hypotenuse of the triangle, is 10 feet. How long is the vertical standing stub of the pole? 8 ** CRIMDEBN00000202
