  • Ultrasonic rod waveguide-radiator
    Patent number: 7156201
    Abstract: The present invention comprises an ultrasonic resonant rod waveguide-radiator with at least three cylindrical sections, one of which is an entrance section having a planar entrance surface and another of which is an exit section having a planar exit surface, and at least two sections having a variable cross-section. The cylindrical sections and sections of variable cross-section are arranged in alternating fashion and connected to each other acoustically rigidly. The dimensions of the cylindrical sections and the sections of variable cross-section are selected so that the gain of the waveguide-radiator is significantly greater than unity and the strain created by passage of ultrasonic waves through the waveguide-radiator is minimized, increasing the operational life of the waveguide-radiator and maximizing the amount of useful energy transmitted by the waveguide-radiator.
    Type: Grant

  • Disposable bailer
    Patent number: 5507194
    Abstract: The present invention is a disposable bailer having an elongated tube with opposite inlet and outlet ends of the tube, both ends being integral with the tube and tapered; with an inlet valve means, the inlet end of the tube being continuously molded with the tube to form an internal cavity for containing the inlet valve means.
