Ink Jet Printing    

Inkjet printers in spray mode - bubble valves & magnetically actuated valves to control ink flow.


These inventions relate to inkjet printers in spray mode, using bubble valves and magnetically actuated valves to control ink flow, employing automated optical means to monitor print performance and automated cleaning of optical components. Inventions also describe board-wide inkjet arrays for printing on whiteboards and the use of specialized inks for printing on pre-coated transparencies.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 346: Recorders

Making a record of the movements of machines or instruments whose movements are desired to be recorded and at least temporarily preserved. Making a record of any phenomenon capable of being detected either quantitatively or qualitatively and recorded for at least temporary preservation: The preceding in general require (a) the means to make the record, (b) the means to detect qualitatively or quantitatively the movement or other phenomenon, and (c) the means actuated in accordance with the movement or other phenomenon to cause the record making means to function.

Subclass 140.1: With ink supply to marker

Class 382: Image Analysis

This is the generic class for apparatus and corresponding methods for the automated analysis of an image or recognition of a pattern. Included herein are systems that transform an image for the purpose of (a) enhancing its visual quality prior to recognition, (b) locating and registering the image relative to a sensor or stored prototype, or reducing the amount of image data by discarding irrelevant data, and (c) measuring significant characteristics of the image.

Subclass 256: Object boundary expansion or contraction
Subclass 257: Dilation or erosion (e.g., opening or closing)
Subclass 266: Edge or contour enhancement

Class 347: Incremental Printing Of Symbolic Information

Processes and apparatus for conveying information by selectively creating on a medium a visibly distinguishable symbol or mark composed of a plurality of portions; created portion by portion as, for example, by pixels or dots. The symbol or mark may be an alphanumeric character or an image.

Subclass 104: Physical handling
Subclass 188: Density control
Subclass 33: Wiping
Subclass 37: With means to scan fluid ejector relative to the receiving medium
Subclass 56: With thermal force ejection
Subclass 65: Flow path
Subclass 85: Fluid supply system
Subclass 92: With means to remove and/or accommodate bubbles in the fluid

Class 366: Agitating

Apparatus for, and corresponding methods of operating on fluid, viscous, plastic, or fluent particulate material solely for causing portions of the material to move irregularly with respect to each other so as to intermix. The material may be in motion or at rest immediately before agitation.

Class 417: Pumps

This is the general class for the pumping of fluids, and includes the pumping of slurries, fluent material and the like if handled in a manner not inconsistent with the handling of fluids. A pump is defined as means to move a fluid by taking it from one place or location and moving it to another place or location different from whence it came, the pump, therefore having an inlet and an outlet for the pumped fluid which are separate and distinct. The pumping of the fluid is generally accomplished by action thereon of a mechanical member (eg. piston) or by contact or entrainment with another fluid (eg. jet pumps). Also, the pumping may be accomplished by the direct action on the pumped fluid of an electric or magnetic. This class is the residual home for the formation of a vacuum in an enclosed space by a gettering action; a getter being a material which when placed in an enclosed space reduces the gas or vapor content of the space either by a chemical or physical action. Also, included are those devices and processes in which the fluid is ionized to permit or enhance the gettering action. These devices are often termed "getter-ion pumps".

Subclass 208: Vapor generator type

Class 101: Printing

Means not otherwise provided for adapted to produce characters or designs on surfaces by impression of types or dies or by applying coating material thereto through openings of previous portions of a pattern sheet, as in stenciling, or by impression from planos:graphic or intaglio surfaces.

Subclass 211: Processes
Subclass 491: Specific ink

Class 428: Stock Material Or Miscellaneous Articles

This is the residual class for: 1. Stock material in the form of a structurally defined web, sheet, rod, strand, fiber, filament, cell, flake, particle not provided elsewhere. 2. Stock material in the form of a web, sheet, mass or layer which consists of or contains a structurally defined constituent or element. 3. A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.

Subclass 195.1: Discontinuous or differential coating, impregnation or bond (e.g., artwork, printing, retouched photograph, etc.)

Class 400: Typewriting Machines

This is the generic class for an apparatus wherein a user of the apparatus causes an intelligible character* to be imprinted on a record-medium* by a type-member* that is impressed on the record-medium, said type-member being selected from a plurality of different type-members, and the selected type-members being impressed serially to form a sequence of characters that record intelligible information.

Subclass 48: Work support (e.g, sheet or card holddown or guide, sheet-size platen, etc.)

Class 251: Valves And Valve Actuation

Means for regulating flow of a fluid through a passage, either by closing the passage or restricting it by a definite predetermined motion of the closing-element, that are of general application not otherwise provided for.

Subclass 129.17: Having diaphragm between coil and opening controlled
Subclass 129.2: Mechanical movement between valve and solenoid
Subclass 331: Diaphragm
