A poultry vaccinator for use in brooding houses having multiple layered rows of cages for high volume vaccination. The vaccinator apparatus includes a plurality of atomizer nozzles disposed at multiple elevations on a collapsible stand pipe assembly. A single reservoir provides a common source for vaccination liquid for each of the atomizer nozzles. Calibration orifices located in the liquid lines to each of the atomizer nozzles provide pressure compensation for elevational differences of the nozzles. Thereby producing a uniform particle size aerosol out of the nozzles regardless of nozzle elevation.

Multi-layer poultry vaccinator

Disclosed is a pulse-jet engine powered, fog producing device using a carburetor to feed atomized fuel to the engine combustion chamber, the carburetor operation being characterized by a positive pressurization of a diaphragm-walled chamber to open a fuel inlet valve during the engine starting interval, and provision of a positive pressure fuel delivery to the carburetor utilizing the combustion pressure pulses of the engine as the fuel pumping impetus.
