Abstract: Deblinding apparatuses and deblinding methods are provided. A deblinding apparatus may include a support frame including a grid structure and multiple compartments. Multiple compartments may be formed by a respective portion of the grid structure and a respective set of support members. Further, multiple scattering members may be disposed within a compartment. Scattering members be removably affixed to a portion of the grid structure that forms a part of a compartment. Multiple unsecured objects may be placed within a compartment. When attached to a screen and in response to movement of support frame, at least one unsecured object of the multiple unsecured objects may collide with a first scattering member and with a surface of the screen to thereby cause deblinding of the screen. Sizes, shapes, masses, and morphologies of unsecured objects may be designed to optimize collision rates of unsecured objects with scattering members and with the screen assembly.

Abstract: An undulating molded plastic vibratory screen including a base, a plurality of spaced substantially parallel undulations on the base, screen configurations on the undulations, and supporting rib structure within the undulations.

Abstract: Disclosed within is a fist bracket comprising a base and a circumferential portion extending from the base in which the circumferential portion comprises an outer surface and an inner surface and the outer surface comprises a curved section and a planar section. Also disclosed within is a combination of a motor mount bracket and fist bracket comprising a fist bracket with a base and a circumferential portion extending from the base. The circumferential portion includes an outer surface and an inner surface and the outer surface comprises a curved section and a planar section. The combination further includes a bushing disposed within the circumferential portion of the fist bracket.

Abstract: A vibratory motor having an elongated housing having opposite ends, an electric motor positioned within the housing between the opposite ends, bearings in the opposite ends, a motor shaft extending into the opposite ends and supported by the bearings, eccentric weight chambers in the opposite ends proximate the bearings and between the bearings and the electric motor, explosion and leak-proof seal assemblies located proximate the eccentric weight chambers and between the eccentric weight chambers and the electric motor, each of the seal assemblies including an oil seal facing an adjacent eccentric weight chamber, and a flame path between the oil seal and the electric motor.

Abstract: A vibratory screening machine having a single vibratory motor mounted on its inner resiliently mounted frame by motor mounting structures at its ends, each motor mounting structure consisting of a combination of a fist bracket carrying a directionally stiff bushing with the fist bracket being mounted in a motor mount bracket with the fist bracket having a first cutaway portion positioned within a second cutaway portion in a rib on the base of the motor mount bracket. The directional stiffness of each bushing is aligned with the center of rotation of the vibratory motor, and this will produce linear motion when the unbalance of the vibratory motor is in line with the center of rotation of the motor and the direction of the directional stiffness of the bushings.
