Abstract: A screening plant having a feed plate located between a grizzly grate and a conveyor driven by a hydraulic motor. A first source of fluid supplies hydraulic fluid to a first cylinder to open the feed plate and to a second hydraulic cylinder to swing the grizzly grate. A second source of fluid provides hydraulic fluid to the hydraulic motor driving the conveyor and to a sequence valve at a pressure determined by the load on the motor. The sequence valve stops the flow of fluid to the second cylinder stopping the feed plate when the pressure of fluid from the second source of fluid reaches a predetermined value so that the conveyor will not be overloaded. The feed plate has to open at a preset speed and is started and stopped by the discharging conveyor, as the conveyor meets its capacity. When the feed plate reaches full open position, it activates a control that lifts the grizzly grate and dumps off large pieces of material. The grizzly grate is also controlled by the discharge conveyor.

Abstract: A padding machine used for overlaying a pipeline disposed within a trench with sifted dirt to eliminate contact by rock or other abrasive material with the pipeline and, thereby, preclude rusting, corrosion or like damage. A trench typically lies along the edge of a right-of-way on which the padding machine travels, i.e. pulling, for example, as from a tractor. Raw filling material is introduced onto a shaker driven and/or vibrating screen through the use of, for example, a common backhoe. Rocks or larger sized particles move, by gravity, onto the right-of-way adjacent the side of the machine opposite to that of the trench, where sifted filler material passes onto and from a moving conveyor which is directed toward the desired covering relationship with the pipeline. A feature of the padding machine is the use of a boom which interconnects the freely vertical movable front end of the padding machine to a towing vehicle and includes an hydraulically operated piston for leveling purposes, i.e.

Abstract: The size ranges of particles separated on a stack of sieves of different mesh sizes is measured automatically. The stack is clamped together and shaken as a unit to separate the respective fractions, following which the sieves are sequentially separated from the stack and inverted one at a time to dump the fraction retained on each, onto a scale. Each fraction is weighed separately and their relative proportions can be calculated automatically. In a preferred embodiment the sieves are individually cantilevered from a vertical conveyor. The sieves are inverted one by one to dump their contents by advancing them around a horizontal roll at a lower end of the conveyor.

The package has a partition member insert comprised of an apertured screening section and at least one imperforate ramp section inclined towards the screening section. The screening and ramp sections are supported above the bottom of the container to provide for sifting of the crumbs through the screening section, while the package is in its normal upright position, and to allow the crumbs to gravitate into the trapping space, defined by the imperforate ramp section, the bottom closure and the surrounding walls, when the package is tilted during pouring.

Abstract: This invention is a simple, easy to use, self-cleaning pet litter box that separates reusable litter material from solid pet droppings. This task is accomplished through the use of swelled-out chutes strategically formed along the litter box walls combined with a trough-shaped, wire mesh separator that is also built into the litter box. A hole is cut in the side wall adjacent to the wire separator with a tubular-shaped protrusion extending from the outside of this hole in the wall. By using a tilting, rotating motion, the used litter is passed through the chutes in the walls and into the wire mesh separator. The solid pet waste is trapped in the separator while the still usable litter is filtered through. With one final tilt, the solid waste is dumped through the hole in the wall, through the tubular protrusion, and into an attached disposable plastic bag.
