Abstract

530,632. Ventilators; heating air. HELLEN, J. L. June 15, 1939, No. 17545. Convention date, June 15, 1938. [Class 137] [Also in Group XIII] Fresh air from an inlet channel 7 passes, under control of a cylindrical rotatable valve member 2, through a passage 3 leading to a radiator R, and through ports 10 leading direct into an enclosure, the front wall of the casing 5 being made integral with the valve casing 1. By rotation of the member 2 the passages 3 and ports 10 are uncovered in turn. Specification 490,702, [Group XIII], is referred to.
