  • Patent number: 7396052
    Abstract: A sanitary connector apparatus includes first and second tubular members coaxially aligned such that a first member end of the first tubular member is positioned toward a second member end of the second tubular member. First and second sealing components radially extend from the first and second member ends, respectively. An annular groove is formed into the first end face of the first sealing component and a corresponding resilient rib is integrally formed with the second end face of the second sealing component. A clamp band, secured around the outer perimeter of the first and second sealing components, has two extension members that apply compressive force to the sealing components in a direction coaxial to the tubular members. The compressive force applied is sufficient to compress the resilient rib into the corresponding groove and position the first end face against the second end face.

  • Patent number: 6349834
    Abstract: A vibratory screen separator having a resiliently mounted frame with a screen mounting to receive screens for material flow thereacross. Eccentric weight systems are rotationally mounted with effective axes of eccentric force coincident. The weight systems are symmetrical about a center plane through the separator for uniform vibration thereacross. The coincident axes extend through the center of gravity. A drive is coupled with both weight systems such that the direction of rotation of the weight systems are opposite to one another in one embodiment and opposite in another.

  • Patent number: 5456365
    Abstract: A vibratory screen separator using screens with screen frames. The resiliently mounted housing has a first wall portion having an upper edge and a second wall portion above the first wall portion having a lower edge, the upper and lower edges being mutually aligned and defining a seat therebetween to receive a screen frame, each mount being coupled to the first and second wall portions and having a first position with the upper and lower edges gripping the screen frame and second position with the upper and lower edges mutually displaced from the first portion and the screen frame released.
