(under the class definition) Apparatus comprising either a nozzle or a strewing means to project or scatter a fluent material, and means to create an air stream related in a manner such that the fluent is discharged into the said air stream and further characterized by a disclosure that: (1) the air stream has a cross sectional area and a volumetric flow which are very large as compared with the outlet area and volumetric flow capacity of the nozzle or strewing means, (2) the apparatus is provided with means rendering it mobile (e.g., wheels) and (3) the fluent is conveyed by the air stream onto a tree or trees.
(1) Note. Liquid and air pumps unitarily constructed are included if discrete air and liquid impelling means are included, as for example, a centrifugal slinger with air vanes thereon.
(2) Note. If vaporization takes place by heat and the result is a smoke which is discharged and the sole disclosed or claimed use for the smoke is for insecticidal purposes, classification is in Class 43. If there is no purpose disclosed for the smoke, classification is in Class 516. If there is no vaporization, but liquid is discharged classification is in Class 239.
