TALLMAX, Chairman and President of Tallman-M cCluskey Fabrics Company, died December 17, 1968 at age 84. Mr. Tallman was well-known in the Asbestos Industry and had been active in the Asbestos Textile Insti tute for many years. JUDA DIENER, former Vice President of Smith & Kunder Company, passed away January 5, 1969 at the age of 72. Mr. Diener had been with S&K until ten years ago, at which time he became a building contractor in San Juan, Puerto Rico. R API STAX I XCORPQRATED describes its vibratory conveyors in Catalog 4300. The new literature shows both coil spring and leaf spring models for handling a wide variety of bulk materials. Xaturai frequency and dynamically balanced models for high temperature, sanitary and other special appli cations are illustrated, along with models for conventional bulk handling purposes. . CALI DPI A ASBESTOS is described in a new ten-page brochure published bv Union Carbide Corporation. A unique and versatile fiber. CALI DEI A Asbestos has been proven for application as an extender, a thickener, a reinforcer and an opacifier. It is of the Chrysotile variety and is obtained from a short-fiber asbestos deposit in the Xew Idria area of the Diablo Mountain Range in central California. Union Carbide uses the wet process to produce all CALIDRIA As bestos products. This process is described as a treatment which breaks down the fiber bundles and removes the rock and other foreign contaminants of the ore body, leaving- essentiallv pure asbestos. A distinct result of this process TsAlie ability to oiler aireconomic pelletized asbestos product. Ad vantages of this form arc! ease of handling, leduced dust, lower shipping rates, and less troublesome and .costly storage. CALIDRIA Asbestos pellets are fg-inch in diameter by 4incli in length and can be. handled by conventional dry bulk handling systems.

To make a component, tbp cavity of a female mold is spravcd with a polyester gel coat to a thickness of .025". After the gel coat sets, it is sprayed with the base structure of glass fiber and polyester resin to a nominal thickness of 3/16". The completed'component is then removed from the mold. The gel coat was originally formulated from a polyester resin, a filler and a viscosity control agent (thixotrope) of colloidal silica. Substitution of a resin-grade asbestos for the colloidal silica as the thixotrope in the gel coat has resulted in significant cost savings for the manufacturer. The asbestos costs about half as much as silica, has higher yields, gives better batch consistency using less thixotrope and is more readily wetted by the resin without fluffing up. making spraving quicker and easier. The asbestos used is Union Carbide Corporation's C. l /-- I DRI A Asbestos. Resin-Grade 244. Material cost savings in the range of $10.00 per 800-pound batch are being realized, stability problems are eliminated and viscosity is maintained during lengthy storage periods. G EN U IN E PITSEA L is an emergency gasketing ma terial that will become semi-plastic with the natural heat gen erated by the metal surfaces between which it is Used. It is for use where a flange or a joint is badly pitted, scored or distorted and when plant down-time is impracticable due to cost factors or loss of production. The material is composed of long-strand asbestos fibers which are interwoven with white allov wire containing a special imported graphite. It will take pressures up to 350 psi and temperatures to 450F and is available in sheet sizes 40" x 40" and 40" x 80" with V&"> /ie" and Via" thicknesses. Free samples of the gasketing material are available from the .manufacturer, Industrial Hermetic Materials. Inc.. Miami, Florida. Page 30 ASBESTOS -- September 96? PATENTS A b s t r a c t s of U. S.
