Product: Automatic vapor phase chromatograph. Features: A fixed sample of gas is introduced into a carrier gas stream (helium, hydrogen, nitrogen) a n d washed down through a chromato graph column by the flow of the carrier gas. T h e control unit m a y be located as m u c h as 500 feet away. Uses: For analysis of gases. C a n be used as a steady monitor on plant stream, such as in a refinery. Manufacturer: Dept. IEC, Con solidated Electrodynamics Corp., Pasa dena, Calif.
Data Processing Service for Industry O n e of the big features of this new kind of d a t a processing service is its versatility.

Feeder for Dry, Free-Flowing Materials Product: Self-powered feeder to control the feed of dry materials at rates from 200 to 2000 pounds per minute. Features: Operates on the principle of balanced weights. T h e force produced by the material being fed as it falls onto an impact p a n is balanced by a preset counterweight. Uses: C a n be used in any plant where feed rate of dry materials must be controlled. Manufacturer: Dept. IEC, Wallace & Tiernan Inc., Belleville 9, N. J.
Moisture Monitor for Gaseous Mixtures Problem : T o measure accurately minute quantities of moisture in gaseous mixtures. Solution: A new, portable, lowcost, a n d accurate instrument called the Moisture Monitor. It will meas ure water content accurately down to 1 p.p.m. a n d permit precise meter readings over the full-scale range of 0 to 1000 p.p.m. by means of a fivestep attenuator. Monitoring water content in n a t u r a l gas transmission lines is one use for which it is sug gested. Another is monitoring a n d control of water contents of cylinder and bottled gases to assure moisturefree manufacture. T h e monitor operates on 50/60-cycle, 105- to 125-volt alternating current. Nor mal line transients do not affect its operation. Sample flow, at tem peratures u p to 100° G. a n d pressures of 5 to 100 p.s.i.g., is controlled at a selectable flow rate of a b o u t 100 cc. per minute. Dept.
