Portable Platform Hel) Wa>h Insulators PACtrtc Gas & Electric Co had prob lem of removing dutf and debris irom city power-pole insulators before Uart of rainy season. To do a fast, thorough job, the company bought a telescopic ram from e tree firm. Ram has s small platform; rig is set on a lank truck, which carries 2000 gallons of water. Now, with a hose and 60-psi pump, a workman rides the rig along the streets, raises and lowers himself si will, end squirts the insulators clean by s jet of water from a hand-held noule. Water is tested to be sure Its electrics! re sistance is high enough to prevent dan ger to hoseman up on platform. C F Dunragr Oakland, Calif. Condenser Stands Must Be Rigid It's ho use doing a first-class job of hooking up heat exohangers, conden sers and receivers if they are not sup ported on a solid stand.

This engine is available In 12 or 16 cyl inders of 13* bore in Diesel,Duafuel or Spark-Fired Gas types from 2400 to 4260 hp at 430 to 600 rpm. The design of this V-Type engine incorporates all tested and proved performance features of Nordberg 13* bore in-line SUPAIR THERMAL engines. The high thermal efficiency of the SUPAIR Noil-Pulling Kink In pulling nails, work is often elowed down because they wedge into claw slot. Then you have to remove each nail from claw by hand. Simple way to prevent wedging is to jam one nail into place "upside down," sketch. Snip off point. You can then pull nails without any hitch. If right* sited nail is wedged, the next nail being pulled falls out of claw by itself. S V W<jaTit New York, N. Y. Handy Trick Unklnks Rope Here's one wav to get kinks out of oew rope when preparing a batch for serv ice. It has these advantages: (1) It's done quickly in a smell space. (2) Rope is unharmed, dry, and ready for imme diate etorage or service. When novices try this job without being shown how it's done, they usually snarl rope bodly. f have seen 1200 ft of new rope towed . behind a bool in water until kinks came out.
