International Classification:

B01F 722

US Classification:

3661722, 366264, 366270, 422227

Abstract:

A mixer for preparing silver halide grains for photographic use has upper and lower impellers housed in a draft tube. The bottom impeller has flat blades for micromixing silver and halide reactants introduced into the bottom of the draft tube. The upper impeller has pitched blades for macromixing the bulk fluid. The impellers are spaced apart at least the distance of their diameters so that the upper and lower impellers operate independently of one another so that micromixing is independent of macromixing. A flow disrupter structurally associated with the draft tube and positioned above the top impeller prevents vortexing of the fluid during mixing. Baffles may be provided in the draft tube to discourage vortexing.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G09G 500

US Classification:

345700, 345965, 399 81

Abstract:

A programmable message storage system for a multifunctional printing system is provided. The programmable message storage system includes a configurable database for listing a plurality of message identifiers, the plurality of message identifiers corresponding respectively with the plurality of messages. The plurality of code sets corresponds respectively with the plurality of message identifiers, and each code set controls a manner in which a corresponding message is displayed on the display screen. In practice, at least one of the plurality of code sets is user programmable so that, in response to user input, the at least one of the plurality of code sets is reconfigured in the database for changing the manner in which the message corresponding with the at least one of the plurality of codes sets is displayed as a function of said reconfiguring.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G06F 300

US Classification:

345764, 345522, 345781, 715514, 715515, 715520

Abstract:

A document processing control system with a graphical user interface having a display is provided. The document processing system further includes a memory manager for determining whether the information of the information set is of a first type or a second type. The memory manager uses a first information processing mode to control display of the information when the information is of the first type and a second information processing mode to control display of the information when the information is of the second type.

Appl. No.:

8/708154

Inventors:

Rajesh Vinodrai Mehta - Rochester NY
Donald Robert Irwin - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 1015
G03C 1035

US Classification:

430569

Abstract:

The invention generally relates to a process for forming tabular silver chloride grains comprising nucleating silver chloride particles, introducing alkali iodide solution into the dispersing medium containing the nucleated silver chloride particles, and introducing silver ion and chloride ion solutions into said dispersing medium, with the proviso that introduction of the alkali iodide is by multiple streams of said alkali iodide at a momentum range of up to 1. times. 10. sup. +9 g cm/s. sup. 2.

Appl. No.:

9/182086

Inventors:

Robert J. Dash - Victor NY
Donald Irwin - Rochester NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G06F 300

US Classification:

345333

Abstract:

There is provided a system for a multifunctional printing system which controls a manner in which status message sets are displayed on a display screen of a corresponding user interface. As contemplated, a first service attribute designating set of information is displayed on the display screen at a first time and a second service attribute designating set of information is displayed on the display screen at a second time, with the second time being subsequent to the first time. In practice, a message manager determines whether a replacement operation has occurred with respect to the user interface such that a substantial portion of the first service attribute designating information set has been replaced visually by the second attribute designating information set. In response to determining that a replacement operation has occurred, at least a portion of a status message set currently being displayed is replaced with at least a portion of another status message set.
