Sensible Price... Sensitive Performance . . .The Model CT Conductivity Analyzer Sturdy enough for field or plant operation, yet precise enough for laboratory use, this compact analyzer from Trimar measures temperature and temperature-corrected conductivity in fresh or sea water. The Model CT features an LSI circuit design which provides low drift, high accuracy, and low power consumption. Sensor readings are displayed on a large easy-to-read liquid crystal display and the analyzer can be operated on AC or battery. A recorder output signal for each parameter permits interfacing to stripchart recorders, plotters, or other data acquisition devices. If you're into sophisticated water quality measurement, the Trimar Model CT should be your analyzer of choice.

Latest Research in Cellulose/Paper/Textile Chemistry Fiber Defraction Methods

Preservation of Paper and Textiles of Historic and Artistic Value. II A high-quality reference volume of practical and theoretical information on the care of paper and textiles. The acid content of paper and its negative effect on paper permanence/durability is thoroughly explored; one chapter describes the advantages of alkaline papermaking. The detrimental effects of aging, humidity, and light (natural and artificial) on paper and textiles are detailed. Advances in Chemistry Series 193, 355 pages, 1981, ISBN 0-8412-0553-1, Cloth. US & Canada «44.75 Export $53.95

Synthetic and natural polymers are studied, and methods for determining atomic positions within unit cells and characteristics of microstructure such as crystallite size are described. Topics include resolution of x-rayintensities by angular deconvolution; diffraction from nonperiodic structures; the structure of the amorphous phase in synthetic polymers; crystallinlty and disorder in textile fibers; and theoretical estimates of helical structure in polynucleotides.

Preservation of Paper and Textiles of Historic and Artistic Value I

Energy Conservation in Textile and Polymer Processing

A comprehensive volume on the care and preservation of books and manuscripts, the care and preservation of textiles, and the estimation of permanence. Specific chapters deal with the tending, care, and restoration of books made with modern acid unpermanent paper, the repair of art on paper, methods of extending the life of acid paper by deacidification, the effects of oxidative degradation, and the drying of books damaged by floods and fires. Advances in Chemistry Series 164, 403 pages, 1977, ISBN 0-8412-0360-1, Cloth. US & Canada $49.95 Export $59.95

This volume covers several polymer uses — molded plastics, organic coatings, adhesives, and natural and synthetic fibers. Approaches for energy conservation include redesign of products, reuse of energy and processing temperatures, improvement in equipment efficiencies, the development of new polymers, curing, finishing, dyeing techniques, and the most effective use of textiles in ihdoor habitats.
