  • Liquid treatment system
    Patent number: 8858892
    Abstract: A liquid treatment system has a housing defining an interior space. The housing has an inlet port for receiving liquid into the interior space of the housing and an outlet port for allowing liquid to exit the interior space of the housing. The outlet port is spaced from the inlet port so that liquid flows through the interior space of the housing from the inlet port to the outlet port. An ultrasonic waveguide assembly is disposed within the interior space of the housing and includes an ultrasonic horn disposed at least in part intermediate the inlet port and the outlet port of the housing. The ultrasonic horn is operable at an ultrasonic frequency to ultrasonically energize liquid flowing within the housing. An ultraviolet light source emits ultraviolet light into the interior space of the housing to treat liquid flowing therein.

  • Ultrasonically controlled valve
    Patent number: 7178554
    Abstract: An ultrasonically operated valve a source of ultrasonic energy for excitation of a pressurized liquid. The vibration of the ultrasonic horn imparts a pulsing of the pressure of the liquid within the valve. Selection of a sealing mechanism that responds at a different natural frequency than that of the valve body causes the sealing mechanism to unseat and therefore to enable liquid flow. The sealing mechanism will stay unseated as long as the source is imparting energy to the system and therefore inducing pressure pulses in the liquid thus keeping the sealing mechanism away from the valve seat.
