Abstract: A hopper loader having a hopper connected to a vacuum source for applying a vacuum to the hopper to convey material into the hopper through a material inlet. A material separator is disposed between the material inlet and the vacuum source for filtering the material. A material discharge assembly is connected to the hopper and disposed for controlling downwardly gravity flow of the material from the hopper, the material discharge assembly having a material outlet configured to be opened and closed to control the discharge of material from the hopper. A vacuum detector is disposed between the material separator and the vacuum source. A vacuum activated control operatively connected to the vacuum detector and configured to turn off the vacuum source in response to a signal from the vacuum detector.

Abstract: A material handling system. The system includes a plurality of material sources for providing material to be transferred and a plurality of destination locations for receiving material from the material sources, wherein each destination location has a destination valve. The system further includes a distribution mechanism, a plurality of source conveying tubes each connecting a source location to an opening on the distribution mechanism, and a plurality of destination conveying tubes each connecting an opening on the distribution mechanism to a destination location. The system further includes a vacuum source operatively connected to each of the destination valves, a vacuum sensor disposed on each of the source conveying tubes configured to sense a change in pressure in the source conveying tube, and a programmable controller connected to each of the vacuum sensors for determining if a correct connection has been made.
