Phosphating Analysis Kit Development of a phosphating analysis kit has been announced by Turco Products, Inc. Offered free of charge to any 'iianufacturer in the metalworking field, it enables him to determine whether the phosphating process and its paint-adhesion advan tages can be used on his products. Turco's phosphating line has been broadened and no κ offers processes that can be tailored to fit any production or cost requirement, according to the com pany. Processes currently in use range from small, three-tank setups to elabo rate eleven-stage spray washing sys tems. P-25 Transistorized Jtl-Ray Thickness Gagt; The Raymike 600 transistorized x-ray thickness gage is introduced by General Electric Co. The instrument is said to be capable of gaging steel up to 600 mils thick. Designed for hot and cold strip rol ing mills, it features transistorized plug-in electronic panels, and use of a balanced or dual beam x-ray system. G.3 says the accuracy of this gage allows continuous toler ance control of strip to better than 1% of thickness being measured. P-26 Analyzer and Processor Ulver Model 2834 analyzer and processor is desigied by Axler Asso ciates, Inc. for determination of oil and phenols in refinery effluents by API methods 733 and 717. The analyzer, a portable unit, uses a selected grating vith f/4.5 optics, and fixed slits yield an 8-millimicron band width. Wave lenglh is adjusted at 2.82 or 3.43 microns for analysis of phenols or oil, respectively. Analysis may be made with cells liaving path length from .01 to 5 cm. A thermocouple is used with its associated narrow band, low frequency, higr gain amplifier. An electronically regulated power supply ensures stable performance of the am plifier and metering circuitry. Power requirerr ents are 100-120 volts, 60 cycles, current 140 watts. Sen sitivity is 1 p.p.m. oil in carbon tetra chloride, using a i-cm. cell. P-27
