Abstract

An account is given of the development of a spray nozzle consisting of three steel hypodermic needles coaxially arranged to form three concentric tubes. Air from the inner passage and outer annular orifice atomizes the liquid issuing from the intermediate annular orifice. The resultant effect is an improved control over spray breakup and deposit. A description of the nozzle, its performance characteristics and some application to the study of insect toxicology are presented.
