Abstract: A vibratory separator having a basket for supporting screen apparatus for treating material, the basket pivotably mounted on a base, vibratory apparatus connected to the basket for vibrating the basket, the material forming a pool on the screen apparatus, and a beach formed on the screen apparatus, measurement apparatus connected to the basket and positioned above the screen apparatus for measuring a distance from the measurement apparatus to a top surface of the pool, control apparatus for controlling and in communication with the measurement apparatus for receiving signals therefrom indicative of said distance, which distance is indicative of pool depth at that location and which correspond to beach extent, and adjustment apparatus controlled by the control apparatus for adjusting angle of the basket, thereby adjusting extent of the beach.

Abstract: A vibratory separator (in one aspect, a shale shaker) and methods for using it, the separator in certain aspects having a base, a basket movably mounted on the base, screen apparatus on the basket, material flowing onto the screen apparatus for treatment, at least a portion of the screen apparatus not inclined downhill (e.g. said portion horizontal or uphill), electromagnetic vibratory apparatus connected to the basket for vibrating the basket and the screen apparatus, driving apparatus for driving the electromagnetic vibratory apparatus, and control apparatus (on-site and/or remote) for controlling the driving apparatus and the electromagnetic vibratory apparatus; the material, in one aspect, being drilling fluid material with solids therein.

Abstract: A vibratory separator and methods for using it, the separator in certain aspects having a base, a basket on the base, motor apparatus for vibrating the basket and screen apparatus thereon, variable frequency drive apparatus for selectively driving the vibratory motor apparatus, and, in certain aspects, angle adjustment apparatus for adjusting angle of the basket; and, in certain aspects, for sensing a parameter indicative of operation of the vibratory separator, and control apparatus for receiving signals from the sensor apparatus, for controlling the separator based on said signals; and, in certain aspects, for automatically signalling a drive apparatus to change the speed of the motor apparatus; and, in certain aspects, the vibratory motor apparatus connectible to the basket at a plurality of locations so that a motion profile of the basket is selectively variable between linear, elliptical, and circular motion.
