Patent number: 6892889Abstract: A screen system employs a resiliently mounted housing, a vibration generator mounted to the housing, a mounting frame fixed to the resiliently mounted housing and a support surface. This system receives a screen including a screen frame and pre-tensioned screen cloth. The frame includes an inwardly extending mounting flange accessible from below the screen when placed in the housing. Clips pivotally mounted relative to the mounting frame include a first rounded lever extending upwardly to selectively engage the inwardly extending mounting flange. Second levers extend downwardly to cooperate with actuators. The actuators include inflatable bodies with contacts which, upon inflation, force the clips to engage the inwardly extending mounting flanges. This engagement retains the screen on a resiliently mounted housing and is able to further tension the screen in place.Type: GrantFiled: November 5, 2002Date of Patent: May 17, 2005Assignee: M-I, L.L.C.Inventors: Ari M. Hukki, Keith J. King

Patent number: 6096210Abstract: A vibratory separator having a resiliently mounted housing with a vibratory drive. A screen extends across the housing and a cover is positionable over the screen. The screen includes a discharge port therethrough aligned with a discharge passage for removing material from the top of the screen from the system. Another discharge passage cooperates with a manifold plate extending across the separator beneath the screen. An access port is provided through the cover and arranged to receive a discharge plug which can selectively close the discharge hole through the screen. In operation, separating or dewatering is first accomplished, the energy level of the vibration is reduced and a vacuum is drawn above the screen. Bleed air is allowed into the separator below the screen with a restricted flow so that a vacuum can be drawn. Once the material has dried, the vibrational energy can be increased and the plug removed from the hole through the screen. The process material may then be discharged from the unit.Type: GrantFiled: August 31, 1999Date of Patent: August 1, 2000Assignee: Emerson Electric Co.Inventors: Azar M. Hazrati, Bradley N.
