MANUFACTURERS' LITERATURE
measuring
pilot model synthetic resin kettles. These kettles are made of stainless steel and are available with a choice of Dowtherm, electric, or steam heating plants. Cooking conditions in produc tion kettles can be exactly duplicated. In addition to the heating plant, the kettles have cooling elements, con densers, and all recording and indicating controls. Bull.

FLOW-METER KIT does it quickly, efficiently!
Pumps. New catalog lists complete line of rotary pumps and hydraulic pump motors. The pumps featured in the catalog have only two moving parts— equal sized pumping gears—operating in a case with proper amount of clear ance. The manufacturer also has pre pared a helpful manual on how to solve pumping problems. This manual illus trates such problems as unloading tank cars of given capacities in a given amount of time, and should be very helpful to process engineers in choosing the best pump for certain applications.

Here is an easy-to-operate, port able kit which measures liquid flow-rates in the range from 0.025 cc to 2100 cc per minute and gases from 2 cc to 38,000 cc per minute. These wide ranges are handled by four interchangeable glass flow-tubes, with two cali brated glass and four calibrated steel ball floats. In operation, the flowing gas or liquid lifts the cali brated ball. The scale is read at the point of balance, and a graph supplied shows the corresponding flow-rate.
Radioactive Measuring Instruments. New catalog illustrates and describes over 30 new radioactivity measuring instruments. Featured are: scaling units, rate meters, gamma-ray spectrom eter systems, scintillation detectors, portable survey instruments for alpha, beta, gamma, and neutron measurements, and nuclear accessories. A four-color insert is included which describes and illustrates typical instrumentation for a nuclear biochemical laboratory, an in dustrial nuclear research laboratory, and four typical medical radioisotope labora tories.
