  • Publication number: 20110091309
    Abstract: A mechanism for inverting containers or other objects. The mechanism inverts the container or object a full 180 degrees while providing motion control without the use of hydraulic actuators; thereby eliminating the costs, maintenance, environmental issues, and contamination concerns associated with hydraulic systems. The primary application for the inverting mechanism is inverting containers for the purpose of emptying the contents. The mechanism may also be employed to rotate a variety of other objects in other applications.

  • Patent number: 5595442
    Abstract: A tumbler loader assembly is capable of moving a container to be tumbled from a conveyor loading area into a tumbler device using a feed cart while maintaining a low cart profile. The feed cart is capable of moving the container on conveyor rollers along the feed cart as well as having the capability for movement along a guide rail from a first position where the container is loaded onto the feed cart to a second position interior of the tumbler. The tumbler device has raising and lowering capability for interengaging the feed cart as well as for positioning the container for proper tumbling. Upon loading of the container onto the feed cart, the feed cart moves along the guide rail into the tumbler. The tumbler lowers to interengage the feed cart. The feed cart then transfers the container into the tumbler and the tumbler raises to allow the feed cart to return to its starting position.

  • Patent number: 5595491
    Abstract: A 240 volt electrical circuit comprised of modular components which quickly assemble in a manner such that all wiring is completed in the electrical box prior to installing the 240 volt receptacle module, thereby eliminating the need for extra length wires in the electrical box and the cumbersome wiring practices associated with conventional 240 volt electrical circuits. The 240 volt receptacle module plugs into the prewired electrical box, thereby providing quick and easy removal and replacement of the module in the event of failure. The 240 volt electrical circuit is self-configured by simply assembling the modular components. A dedicated earth ground is self-distributed to each electrical component with no effort on the part of the installer, thereby providing safer electrical circuits.

  • Patent number: 5437415
    Abstract: A drum conditioner which is capable of providing an external force on a drum so as to crack and loosen powdered or other finely divided material therein which has solidified and hardened is disclosed. The drum conditioner includes two pairs of pressure rollers which provide pressure to the drum and help rotate the drum as it sits on a conveyer bed of rollers. The pair of pressure rollers in the rear are adjustable so as to accommodate different size drums. The front pair of pressure rollers are provided with a hydraulic cylinder to assist in providing and maintaining pressure between the pressure rollers and the object drum, regardless of the regularity of shape of the drum.
