Although the L*b was built for checking IT&T equip ment, it will handle, on a fee basis, standardization work for outside organ izations. T h e l a b is equipped to provide standard testing of gage blocks, threaded ring gages, and many other mechanical measurements.

Soluble Tungsten Soluble source of tungsten for use as a furnace additive has successfully completed field tests, according to Electro Metallurgical Co., a division of Union Carbide. Known as self-reduc ing tungsten, it is said to dissolve rapidly and distribute uniformly in a steel melt. The alloy contains tungstic oxide and a reducing agent, yields tungsten directly to melts of tool, die, or other alloy steels, Electromet says.
