TRANSMISSIONS. This is a 16-page bulletin describing the construction and operation of this type of variable speed transmission. It is said to be charac terized by radical simplification, which makes possible a higher degree of smoothness in operation and durability in service. Essentially the variable speed transmission units consist of a volumetric variable displacement pump driving a constant displacement motor. High-grade lubricating oil is used as the power fluid.

The wet collector towers, similar in external appearance to those previously offered, are now made with six dust impingement plates—the seventh of the series being designed for use as a water entrainment separator to gather the re maining moisture from the clean air be fore it is exhausted. Other major design changes include a dirty air baffle under the first impingement plate, wearing strip reinforcing, an air directional baffle on the inlet side in the cyclone chamber, and a screened strainer on the sludge dis charge line.
