The air-inlet and air-outlet tubes of the ozonizer were equipped with 

 the inner parts of standard taper joints so that rubber tubing was not 

 used for these connections. Moisture-free air or oxygen was forced 

 through the ozonizer at the desired rate. Glass tubing was used for 

 all connections and air lines.
