Abstract: A screen retention mechanism for use with vibratory separators is disclosed. The screen retention mechanism includes a structural frame mounted to a vibratory separator into which a plurality of lightweight and flexible screen elements are inserted into multiple tows of perforated screen supports. The perforated screen supports are bonded to the structural frame and are aligned parallel to the direction in which solids are conveyed by a vibratory motion. The invention further features an improved retention mechanism whereby screen elements are conveniently and selectively restrained.

Abstract: Methods of manufacturing screen elements for use with vibratory separators are disclosed. The screen elements include a curved structural frame with perforations therein, the perforations designed to maximize both open area and process liquid throughput. At least one layer of screen cloth is attached to the curved structural frame by means of fluidized powdered epoxy resin.

Abstract: A screen assembly is disclosed for use with vibratory separators. The screen assembly includes a structural frame mounted to a vibratory separator into which a plurality of lightweight and flexible screen elements are inserted into multiple rows of perforated troughs which have geometric shapes. The perforated troughs are bonded to each other and to the structural frame. The perforated troughs are aligned parallel to the direction in which solids are conveyed by a vibratory motion.

Abstract: A new and unique design enhancement and use of directional and re-directional ribs on a solids control filtering screen, such as those used in drilling wells for hydrocarbons and other substances, in conjunction with a coordinated system of hanging such screens and directing and redirecting the flow of trapped solids over the surface of such screens, is disclosed for use with a shaker. The invention counteracts the natural tendency of trapped solids to migrate to and congregate in the lowest areas of a suspended screen and facilitates a dryer fluids discharge, as well as more effectively utilizing the available screening surface area, and therefore the invention reduces the incidence of screen wear and tearing and increases the flow rate conductants through the screen.

Abstract: A high strength window screen frame is hinged for opening. The frame has a stationary frame and a movable frame. The stationary frame attaches to a building. The stationary frame has a protective lip extending forward from its perimeter. The movable frame is secured to the stationary frame by a hinge. The movable frame has a perimeter with a beveled side edge to allow opening of the movable frame without interference with the lip. A screen is secured to the movable frame.

Abstract: A new and unique design use of directional and re-directional raised ribs on a solids control filtering screen, such as those used in drilling wells for hydrocarbons and other substances, in conjunction with a coordinated system of hanging such screens and directing and redirecting the flow of trapped solids over the surface of such screens, is disclosed for use with a vibratory shaker. The invention counteracts the natural tendency of trapped solids to migrate to and congregate in the lowest areas of a suspended screen and facilitates a dryer fluids discharge, as well as more effectively utilizing the available screening surface area, and therefore the invention reduces the incidence of screen wear and tearing and increases the flow rate conductants and drying capabilities through the screen.

Abstract: A high strength window screen frame that includes an extruded metal frame that fits within a window opening in a building. The frame is made up of a plurality of window frame units, each defining an opening and covered with mesh. A standoff leg portion of the window frame units provides a standoff separation of the mesh from a glass pane so that when objects strike the mesh and deflect the mesh, the glass pane is not impacted.

Abstract: A high strength window screen frame that includes an extruded metal frame that surrounds a window opening in a building. The frame defines an opening. A screen plate portion of the extruded metal frame is provided on the frame proximate the opening. A flange portion of the extruded metal frame is provided on an outside of the frame away from the opening. A beveled surface on the flanged portion is provided to improve the appearance of the metal frame. A screen plate stiffener is removably affixed to a back side of the extruded metal frame to secure a screen to the frame. Heavy duty mesh screen is preferably used with a high strength window screen frame of the invention. The flanged portion of the window screen frame is bolted to an exterior wall surrounding a window opening of a structure.
