Abstract: A sensing system for bins includes a bin with at least one light emitting diode operatively mounted to the bin. At least one receiver for detecting IR light from the at least one light emitting diode is also operatively mounted to the bin. A microcontroller is operatively connected to the at least one light emitting diode and the at least one receiver. A wireless transmitter is operatively connected to the microcontroller for relaying information regarding the content status of the bin to an indicator. The at least one light emitting diode, the at least one receiver, the wireless transmitter, and the microcontroller are operatively connected to a power source.

Abstract: A nesting tilt-truck includes a metal frame and a container body. A pair of large wheels are rotatably mounted on a common axle that is in turn mounted on the metal frame near the junction of the container body front wall and base. A second caster wheel or wheels, which house a self-contained axle that allows the wheel(s) to rotate, is mounted on the metal frame near the junction of the container body rear wall and base. The caster wheel(s) are configured to pivot about a vertical axis in order to easily steer the tilt-truck during use of the tilt-truck. The container body is formed with a kick-out wall that inclines rearwardly to form a pocket for seating the wheels of a second tilt-truck when one tilt-truck is nested inside a second tilt-truck.

Abstract: Disclosed is an apparatus and a corresponding method for producing a continuous foamed extrudate product in which the extrusion and initial expansion of the foamed extrudate is conducted within a chamber under a partial vacuum. The foamed extrudate is then removed from the chamber through an orifice submerged within a liquid baffle. The dimensions of the foamed extrudate are monitored as it approaches the orifice and, if necessary, the effective sizing of the orifice is adjusted through the movement of a pair of side gates and a single vertical gate arranged external the orifice to match opening to the foamed extrudate and impede the flow of liquid into the chamber through the orifice.
