Abstract: An apparatus for separating material includes a frame and a rotatable sleeve supported by the frame. The sleeve has a first end, a second end, and a wall with a plurality of apertures to permit material smaller than a first size to fall through the apertures. A source of forced air is arranged to force air through an interior of the sleeve.

Abstract: A commodity container flow initiator is shown for initiating gravity flow of a commodity from a bin having typically four sides and a bottom, wherein one side is the unloading side of the bin when the bin is tipped on that side for unloading, wherein the invention has a substantially rigid planer member comprising a sliding deck that is slidably attached to the inside of the unloading side of the bin so as to allow the deck to selectively slide any direction substantially coplaner with the unloading side of the bin. Hydraulic cylinders are affixed to the bin and to the deck to provide moving force to slidably move the deck.

Abstract: A time of top-over indicator includes a mercury tilt switch connecting a battery to a digital clock with a clock display. The assembly is positioned on structure subject to tilting, such as a refuse container emptied by tilting. When a change of switch state occurs because of tilting of the tilt switch, the clock causes the display to change in such a manner as to indicate the time of occurrence of the tilting operation. In a preferred embodiment, the clock updates the display to show the time of occurrence of the tilting of the container and so maintains the display until the next occurrence of tilting. Alternatively, the clock is reset and restarted in response to the tilting of the container and displays the elapsed time since tilting of the container occurred.
