The F CV Ρ F L O W R A T O R , variable area type flow meter, permits an instantaneous reading of the true flow rate. Each instrument is ac­curately calibrated at our factory for your exact requirements.

Liquid flows down to.0.15 cc per min. and gas flows down to 3.0 cc per min. can be measured with ease. All-glass meters are now sold at E V E N L O W E R prices than prevailed during the war.

Chemical Warfare Association

The Chemical Warfare Association is holding its second annual meeting at the Army Chemical Center, Edgewood Ar­senal, Md., on May 23. All members of the AMERICAN CHEMICAL SOCIETY arccor-dially invited to participate. Tours of the chemical warfare school, technical and medical research laboratories, chlorine plant, and -exhibit of German industrial equipment will occupy the morning. A Chemical Corps demonstration and a

mixer will take place in the afternoon, followed by a dinner and party. Those ex­pecting to attend should notify Ludlow King, president, CWA, 2153 Florida Ave., N. Y\\, Washington 8, D. C , as soon as possible. Cost of all events will be S6.25; of luncheon and demonstration only, S2.

greases—without unfavorable qualities being added—cuts down on consumption. It reduces drip, splatter, or other loss of lubricants from bearing surfaces . . . gives you and your customers a finer product.

SOLKA-FLOC, α unique Brown Company product, is a finely divided, chemi­cally purified cellulose f ibre . It is steadily finding wider uses in industrial operations for both process and product improvement.

Unexcelled in purity and uniformity,soLKA-FLOC is produced in a wide variety of physical forms giving unusual combinations of technical properties. Members of the line are unique in the filler field, being excellent binders from non-abrasive organic origin, low in specific gravity and of negligible ash content. The color range of SOLKA-FLOC is from natural cream to pure white. A variety of fibre lengths is available; bulk, apparent density, and absorbency can be controlled. This rare combination of properties has proved its merit in com­mercial application and SOLKA-FLOC is being profitably adapted to use in the following fields: rubber, plastics, adhesives, protective coatings, ink, filtration, decorative coatings, cosmetics, etc.

For details on how SOLKA-FLOC may be employed to extend supplies o f more critical materials, produce new or better finished products, o r fac i l ­itate manufacturing operations, address our Technical Service Department . Full help will be granted gladly,regardless o f the nature of your o p e r a ­tions, and adequate samples of SOLKA-PLOC supplied·
