2:00 Electrochemical Determination of Glucose Oxidase Using Diphenylamine Sulfonic Acid as a Potential Poiser. G. G. Guilbault, B. C. Tyson, Jr., D . N . Kramer, and P . L. Cannon, Jr., U. S. Army, Edgewood Arsenal, Md. 2:20 Base-Catalyzed Acetylation of Hydroxyl Groups:
a
TECAM® FLUIDISED BATH (patents applied for) Has the advantages of ready access t o contents, high rate of heat transfer and uniformity of temperature w i t h o u t the mess, smell and fire risk of hot o i l . It is an ideal method of testing plastics, elastomers and electrical components because the fluidised sand is neither a solvent nor a conductor. It is a convenient way of rapidly drying samples of fabric, wood and paper. A t higher temperatures it is an excellent tempering and heat ageing bath for metals. The T E C A M « bath will run continuously at 350°C (662°F) from an air supply of 3 p.s.i. obtainable from an air line or from a small vane-type air blower driven by a \ H.P. m o t o r . The pneumatic temperature controller automatically selects one or both of the I k.W. heaters t o give optimum performance at the temperature selected on the drum dial. The unit incorporates a fail-safe device.
