Title: Flexible feeder conveyor system
Inventor: WEYERMANN GARY L
IPC: B65G65/28
Filed: 1992-08-11
Granted: 2000-05-16
Abstract: A flexible feeder conveyor system for removing material from a stockpile and transporting the removed material to a fixed conveyor. The system includes an underconveyor positioned below an excavator and having a loading hopper attached to its forward end to receive material and transport it beneath the excavator a rearward end of the underconveyor. A string of trailing conveyors is towed behind the underconveyor with the last trailing conveyor having its rearward end attached to a stationary terminal support positioned at the fixed conveyor. The underconveyor, the trailing conveyors, and the terminal support are connected together using transition hoppers. Each transition hopper includes an upper hopper mounted to the raised rearward end of the forward conveyor, and a lower hopper mounted to the forward end of the next rearward conveyor. The forward end of the conveyor is rollingly supported by a pair of caster wheels. The upper and lower hoppers are connected together for rotation through both a horizontal plane and a vertical plane. The horizontal rotation is permitted by constructing the upper hopper with an annular support portion and a housing portion rotatably supported thereabove by an annular bearing.      The vertical rotation is permitted by a pair of pivot pins attached to the annular support portion which are loosely received within corresponding upwardly opening slots in a housing portion of the lower hopper to permit the upper hopper to pivot with respect to the lower hopper.

Title: Pressurized flush toilet coupling
Inventor: UNGER JASON D
IPC: E03D1/00
Filed: 1993-01-21
Granted: 1995-08-15
Abstract: A coupling connects a pressurized flush water vessel held in a toilet tank to a toilet bowl.  The coupling has a passageway which provides direct fluid communication between the vessel and the bowl and a chamber for accumulating drainage, which may be exhausted into the toilet tank from inlet devices for the pressure vessel.  A swinging door type one way valve substantially seals against leakage from the passageway to the chamber but allows drainage accumulated in the chamber to flow through a port to the passageway.  The inlet to the chamber is above the port and at or below the bottom of the toilet tank and the port and the chamber inlet open above the spill level of the toilet.  The inlet of the coupling is offset from the outlet and a cradle elevates the pressure vessel above the toilet tank bottom and captures heads of fasteners which secure the toilet tank to the toilet bowl.

Granted: 1998-07-14
Abstract: Various processes for enhancing the contrast between image and non-image regions of a printed image are implemented by increasing the toner-accepting charge on the surface of a printing form having a ferroelectric layer and from which the image is printed. The increase in charge is achieved, in alternate forms of the inventive process, either by increasing the temperature of the printing form surface relative to the temperature at which the form has been polarized, or by mechanically loading the printing form carrying cylinder for transfer of the toner from the printing form, or by applying additional charge carriers to the entire surface of the printing form (30) so as to create an enhanced potential difference between positively-polarized regions and negatively-polarized regions and, thereby, increased contrast between image and non-image regions.
