Automation Sys­ tems for Precipi­ tators. A system which brings com­ plete automation to the power inputs of electrostatic pre­ cipitators, elimi­ nating manual ad­ justments and increasing roundthe-clock dust and fume collection efficiency, is the subject of this new bulletin. The 8-page bulletin shows how optimum performance can be approached more closely by automation than by manual control. Two pages are devoted to a description of how the elec­ tronic feed back circuits of the system control percipitator sparking rate, cur­ rent, and voltage. Dept. IEC, ResearchCottrell, Inc., Bound Brook, N.J. \7

Carbon Monoxide Analyzers. Twocolor illustrated folder describes con­ tinuous carbon monoxide analyzers. The analyzers, which detect the accumu­ lation of dangerous gas concentrations, are especially effective in metallurgical plants, vehicular tunnels, coke oven and gas manufacturing plants. The an­ alyzers are fully automatic. Dept. IEC, Mine Safety Appliances Co., 201 Braddock Ave., Pittsburgh 8, Pa. 18

Stabilizer for Vinyl Resins Developed to provide the vinyl industry with a potent light a n d heat stabilizer, this organotin stabilizer imparts good optical clarity to vinyl products. Vinyls stabilized with this new product do not cross stain when placed against vinyls stabilized with lead or c a d m i u m . T h e new sta­ bilizer is sulfur-free a n d does not have any objectionable odors. Vinyls stabilized with the new organotin derivative have good printability and heat sealing characteristics. Dept.

FLOW-METER KIT does it quickly, efficiently!

Pumps. New catalog lists complete line of rotary pumps and hydraulic pump motors. The pumps featured in the catalog have only two moving parts— equal sized pumping gears—operating in a case with proper amount of clear­ ance. The manufacturer also has pre­ pared a helpful manual on how to solve pumping problems. This manual illus­ trates such problems as unloading tank cars of given capacities in a given amount of time, and should be very helpful to process engineers in choosing the best pump for certain applications.

Here is an easy-to-operate, port­ able kit which measures liquid flow-rates in the range from 0.025 cc to 2100 cc per minute and gases from 2 cc to 38,000 cc per minute. These wide ranges are handled by four interchangeable glass flow-tubes, with two cali­ brated glass and four calibrated steel ball floats. In operation, the flowing gas or liquid lifts the cali­ brated ball. The scale is read at the point of balance, and a graph supplied shows the corresponding flow-rate.

Radioactive Measuring Instruments. New catalog illustrates and describes over 30 new radioactivity measuring instruments. Featured are: scaling units, rate meters, gamma-ray spectrom­ eter systems, scintillation detectors, portable survey instruments for alpha, beta, gamma, and neutron measurements, and nuclear accessories. A four-color insert is included which describes and illustrates typical instrumentation for a nuclear biochemical laboratory, an in­ dustrial nuclear research laboratory, and four typical medical radioisotope labora­ tories.

READ T H I S A R T I C L E ! Experienced ILLCO-WAY engineers compiled the figures for this authori­ tative report from years of pioneer­ ing experience. Nine easily-read charts cover practically every possi­ ble combination of water impurities and contemplated systems of treat­ ment. Costs are shown directly in cents per thousand gallons. With the versatility of this presentation, it is easy to work back and forth over the various choices, to deter­ mine quickly that which would be most acceptable for the given con­ ditions. This article appears on pages 206-210 in the January, 1957, issue of CHEMICAL ENGINEER. ING. We have reprints available and will be very glad to furnish them on request.

Tantalum Equip­ ment. Attractive catalog describes equipment fabri­ cated from tan­ talum.
