any desired liquid into the mixture in any proportion desired. Liquid is sprayed on the blended dry material from both inside and outside the curtain as it falls on a retention plate. Further blending of both solids and liquids is made on the retention plate by mixing blades that automatically discharge the blended and treated material. The complete unit can be supplied on a single base for inside or outside installation. Unit can be equipped with heating elements for cold weather operation outside. Dept.

High Capacity, High Efficiency Centrifuge Availability of a new and improved design of Merco centrifuge with increased capacity and efficiency has been announced. Design permits higher rotor speeds and will handle up to 600 g.p.m. Unit, designated H-30, offers increased capacity without increasing total horsepower requirements. Dept. IEC, Dorr-Oliver Inc., Havemeyer Lane, Stamford, Conn. 2 PCV Centrifugal Pump Application of the excellent corrosion resistance of PVC to a centrifugal pump design opens up a new area for solving many more industries' difficult pumping problems. Available in four sizes, these units offer capacities from 10 to 180 g.p.m. with discharge heads to
Continuous Blender Proportional
Feeding of
Handles Dry or Liquid-Dry A continuous-flow blender which accurately proportions, mixes, blends, and discharges a wide variety of dry materials, or blends liquids with solids in precise quantities has been introduced. The blender, called Verticone, has wide application. It suppresses dust in the unloading of dry solids, blends solids, blends liquid-solid feeds, and prepares the final product for packaging. 96 A
Materials Mixtures Materials to be treated or blended are fed proportionately into the Verticone via controlled volumetric feeding equipment onto the apex of the cone. This cone is the first step in the blending of solids because it causes the material to form a circular, falling curtain as it leaves the base of the cone. At the base of the cone, spray headers can be provided to disperse

Basic design of blenders is that of vertical conical shell in which central rotating shaft carries a number of stirrer blades. Dept. IEC, Colonial Iron Works Co., 17625 St. Clair Ave., Cleveland 10, Ohio 5
How to design smaller vessels, tanks and towers Here's how you can design a smaller vessel that houses a purifier, scrubber, separator or mist extractor. Normally the conventional screen, filter or impingement entrainment device requires a large vessel. Hi-eF Purifiers use no screens or filters and occupy a relatively small area. This permits the use of vessels greatly reduced in size. Saves money. Saves space. Increases entrainment recov ery. Write for Bulletin 802.
In-Line Relief Valve Designed primarily for high pres sure, high flow, and high tempera ture applications, this valve can be reset or serviced without breaking line. Adjustment over a wide range can be made. Available in sizes 8 and 12. Made in pressure ranges up to 5000 p.s.i. Dept. IEC, Republic Mfg. Co., 15655 Brookpark Rd., Cleveland 85, Ohio 6
