its various tanning agents. Appropriate spectacles in a paper frame were supplied to the passers-by. Industry leaders meeting after the open ing day approved a plan to almost double the floor space in the Hall of Chemistry in time for next year's Technical Fair.

Textiles Top Attraction, Synthetic Fibers Emphasized, a t British Fair LONDON.—With an able assist from the synthetic fibers, textile displays proved leading attraetions at the British Industries Fair. At three different locations, Olympia and Earls Court here in London, and Castle Bromwich in Birmingham, the BiF drew crowds of overseas buyers and visitors from April 27 to May 8. Chemicals exhibited by some 50 manu facturers illustrated the widening range oi interest of the British industry, but few new products or development? of significance were in evidence. Teryïene, Ardil, and Nylon. Garments and fabrics made from Terylene and Ardil were displayed by Imperial Chemical Industries. Terylene, ICI's polyester fiber from polyethylene terephthaîate, is produced both as filament yarn and staple. However, company representatives were pessimistic about availability of the new fiber. Buyers were told that it will probably be 1955 before the $28 million Terylene plant is in production. Output is estimated to be 11 million pounds of fiber per year. At the BIF exhibit, emphasis was on Ardil—now available for immediate delivery. Made from the protein of peanuts, Ardil is recommended as a blending fiber. Blended fabrics of Ardil with rayon, nylon, viscose, wool, and silk were shown. The greatest variety of nylon goods ever shown in Britain was exhibited by British Nylon Spinners, Ltd. Fabrics, clothing, stockings, and industrial textiles made from nylon yarns and staple fiber were shown. For the sports enthusiast clothing incorporating silicone-coated nylon was shown by Howard Flint, Ltd. Altogether, more than 200 manufacturers sponsored exhibits covering 120,000 square feet in the textiles section. In addition to the newer fibers, rayon, wool, cotton, silk, and especially blends of these fibers were shown. Perfumes for Plastics. A new series of odoriferous preparations, to be used in association with the manufacture of plastic goods, were demonstrated by W. J. Bush & Co. Trade-named "Plastadors," the products are said to be inert in action, easy to use, and to have no effect on transparency, rheological behavior, or other physical properties of the plastic. A display of realistic plastic flowers incorporating such odors as rose, lavender, and carnation, attracted attention. CHEMICAL
In the field of pharmaceutical intermediates, Hickson & Welsh, Ltd., were advising buyers of their increased production of p-nitrotoluene, and the availability of its derivative p-nitrobenzoic acid. As starting point in the manufacture of procaine and an intermediate in the production of chloramphenicol, p-nitro-benzoic acid is an increasingly important raw material for the pharmaceutical industry. Weedkillers New for Distillers' Group. Of particular interest in the display of the Distillers' Group was the announcement that its associated company, British Industrial Solvents, had started marketing a series of selective weedkillers. The BIS representative states that the products are derived from chlorinated phenoxy-acetic acids and that five alkyl esters of 2,4-D and 2,4,5-T are now available. Recently introduced animal foodstuffs supplements were shown by another associated company, Distillers Co. ( Biochemicals) Ltd. Three products, one containing riboflavin, one vitamin Bi2, and one procaine penicillin were on display. Resins developed particularly for use with glass fibers were shown by Watford Chemical Co. Their thermoplastic Resin E. C , is said to have excellent wetting properties for glass and pronounced resistance to acids and alkalies. Watford representatives suggest it as a bonding agent for glass fibers and as an intermediate bonding agent between glass fibers and other plastic and metal surfaces. With facilities almost ready for full-scale production, the Watford people were pushing their Bentax series of gelling and dispersing agents. Bentax compounds, dispersible in many organic liquids, are organic derivatives of a hydrated aluminum silicate. A rutile type, hitherto available only from American sources·,· was displayed by British Titan Products Co. The firm showed botli rutile and anastase forms of titanium oxide and spokesmen indicated that definite improvements are taking place in the supply picture. The Titan Co. exhibited properties of the pigment and showed typical examples of its use. This was the 32nd year for the BIF. The first fair, held in London in 1915, brought together 581 exhibitors occupying 88,000 square feet. This year's total for all three locations was 2235 exhibitors occupying 882,409 square feet. AND
