Abstract: A device and method for storing toner within an image forming apparatus having an upper reservoir and a lower toner reservoir. A pass through region between the reservoirs may journal a rotatable metering bar. The bar may include convex depressions to dispense toner from the upper to the lower reservoir. The convex shape reduces the toner adherence to the bar, particularly in the case of chemically polymerized toner.

Abstract: An improved sheet printer is provided capable of simultaneously printing both on a “main” surface of a sheet of print media and along edges of that same sheet of print media, such that when the sheets are stacked after being printed, a predetermined image will appear along one or more of the sides of the stack. The “side image” is formed by the dots that have been printed along the edges of the individual sheets. The side image is generated during image processing of the print job, not by a post-processing step of marking or printing against the side of a stack that has already been printed. The printer can form the side images by printing along all four edges of a single piece of the sheet media, and also on one of that sheet's main surfaces, during a single pass through a printing station.

Abstract: The present invention relates to engagement or transfer of an image forming substance within a reservoir of an image forming apparatus. This may be achieved by a device such as a paddle that may include an additional component for engagement or transfer of the image forming substance. The component may be, for example, wire material. The component may also include a body section and an axially aligned projection.

Abstract: An apparatus and process for the transport and isolation of particulate products to and from high pressure, for example supercritical, environments is described.

Abstract: A submerged rotating shaft mechanism, including a gearbox with a gland connected to it and a shaft projecting from the gearbox through and beyond the gland, has an inner seal adjacent the gearbox, an outer, labyrinth, seal adjacent an outer end of the gland, the inner and outer seals forming, with the inside of the gland and the outside of the shaft, a chamber, a fitting communicates, through the gland, with the chamber, and compressed air is supplied to the chamber through the fitting to provide a constant flow of air through the labyrinth seal to flush that seal.
