Screens have been developed which, in one aspect, have interconnection apparatus including male projections on one first screen end which are received in female openings on another adjacent screen end. In one aspect the female openings are defined by raised portions of a three-dimensional screen and the male projections either are formed of the other screen's end or are part of plugs inserted into raised portions of the first screen end. A
sieve shaker has been developed with such screens. In one aspect such a
sieve shaker has screens disposed in a tiered configuration, one screen in sealing contact with the next. Screen connector apparatus has also been developed for such screens.
The present invention is directed to screens; to filtering screens; to devices with vibrating screens; to shale shaker with vibrating screens; to
sieve shaker with screens in series and with tiered screens; and to methods and devices for sealing screen interfaces and for aligning adjacent screens.
New, useful, unique, efficient, non-obvious screens, filtering screens, sealed adjacent screens, aligned adjacent screens for both two-dimensional and three-dimensional screens, for both tiered and non-tiered screens, and shale shakers with such items; A screen for a
sieve shaker with one or more sealing elements secured therebetween and thereto; A shale shaker with a plurality of three-dimensional screens, at least two of such screens each with an end sealed against and aligned with an end of the adjacent screen; and, in one aspect, such a shale shaker in which screens are tiered;
