  • Non-flooding belt feeder
    Patent number: 4475669
    Abstract: A continuous flow, non-flooding gravimetric belt feeder is disclosed which may be used to convey fluid-like particulate material. The feeder includes an endless belt having spaced, transversely mounted cleats. A lateral wall is provided adjacent each of the opposed sides of the cleats and extending between adjacent cleats, thereby preventing the fluid-like particulate material from flowing along the belt, and thereby enabling the feeder to discharge the material at a steady, pre-set rate.

  • Air cooled door handle for heaters
    Patent number: 4448185
    Abstract: The door handle of a heating unit is cooled by providing a duct traversing the interior of the handle from exterior of the firebox of the heating unit to the interior of the firebox. The induced flow cools the handle and provides cool air in the firebox to trap and maintain the hot gasses closer to the fire for a more complete combustion. An open, ellipsoid, spiral coil surrounds the grip of the handle.
