Title: Heat exchange system for processing solid particulates
Inventor: HAIGHT EHRICK K
IPC: B01J8/08
Filed: 1994-04-21
Granted: 1995-11-14
Abstract: A system for heat exchange processing of particulate solid material is disclosed.  The particulate solids are flowed by gravity through a housing packed with flat, internally cooled (or heated) heat exchange panels spaced apart to define generally vertical channels for the passage of the solid particulate.  The panels are formed of opposed metal  sheets,  sealed  around  their  edges,  spot  welded together in limited areas of joinder, in a predetermined pattern over their surfaces, and hydrostatically expanded in the areas between to form surfaces that are quilt-like in appearance.  The panels are configured in two alternate forms such that, when a plurality of panels are assembled in a stack, the hydrostatically expanded portions of one panel are disposed opposite the areas of joinder of an adjacent panel  of  alternate  configuration,  creating  a sinuous, but relatively uniform flow path for the flow of particulate solids between panels.  High system efficiency is achieved by enabling adjacent panels to be spaced closer together while still avoiding the problem of "bridging" of the solid particulate material between panels.

Title: Ink jet printhead having compensation for topographical formations developed during fabrication
Inventor: DRAKE DONALD J
IPC: B41J2/135
Filed: 1994-06-07
Granted: 1999-03-16
Abstract: An improved thermal ink jet printhead is formed by the alignment and bonding of an anisotropically etched silicon wafer channel plate, containing a plurality of channel grooves, to a silicon wafer heater plate, containing a plurality of heating and addressing elements which are covered by a patterned thick film layer. The printhead enables better bonding of the two plates by compensating for raised lips or edges formed on the outside edge of opposing last pits in an array of pits located in the thick film layer that are created while photofabricating the pits in the insulating layer. The fabrication sequence compensates for the raised edges by including a non-functional straddling channel that nullifies the standoff created by the raised edge and a corresponding additional non-functional pit that positions the raised edge away from the functional channels and nozzles.

Abstract: An apparatus for treating process material includes a vessel into which process material can he introduced, an arrangement for introducing steam into the interior of the vessel to heat and impart moisture to process material in the vessel, and several fluid transport conduits extending helically through the vessel for conveying heated fluid through the vessel between opposite ends of the vessel in order to raise the temperature and pressure within the vessel to treat the material while also allowing the moisture content of the process material to be reduced. The fluid transport conduits are also configured to contact the process material and assist in treating and densifying the material.

The vessel can also be interconnected with one or more similarly configured vessels to define a system for treating process material. The system can include an arrangement that allows steam and heat from a hot vessel to be conveyed to a cold vessel. A method for treating process material can include introducing process material into two different vessels, raising the temperature within one of the vessels through the introduction of steam to heat the material in the vessel, and reducing the temperature in the one vessel while also increasing the temperature in the other vessel by venting the interior of the one vessel to the interior of the other vessel.
