Abstract: A chlorinator for wastewater treatment systems having a circulation pump and return flow line, which includes a tank having an internal space, a buoyant container within the internal space which intakes a determined quantity of disinfectant fluid through a check valve from a quantity of such fluid disposed in said tank. The check valve limits flow during operation of the circulation pump. Operation of the circulation pump causes flow through the return line, inducing distribution of the quantity of disinfectant fluid into the circulation tank. After cessation of the circulation pump, the check valve opens to reestablish the quantity of disinfectant fluid. Regardless of the duration of pumping, only the uniform volume of disinfectant fluid is supplied.

Abstract: A debubbling apparatus for removing gaseous bubbles entrained in a liquid is taught which has improved dearation capacity. The debubbling apparatus includes a vessel including a liquid inlet, at least one well extending from the vessel, the at least one well having a liquid outlet, and an ultrasonic transducer horn residing in the at least one well, the at least one well and the ultrasonic transducer horn residing therein being positioned at an angle in the range of from about 20° to about 45° with respect to vertical. With the ultrasonic horn and well so angled, bubbles in the liquid in the at least one well are subjected to a buoyancy force, a drag force, and an acoustic wave force which yields a resultant force that drives the bubbles toward an upper wall section of the at least one well.

Abstract: A comestible extruding apparatus including a pressure chamber having an outlet, a hollow extrusion die journaled in the outlet, and a hollow seal force fit in the outlet and having a neck extending slidably into the hollow die, the neck and die combining to define a rotary seal for the comestible.
