International Classification:

H03K 19177

US Classification:

326 41, 326 40, 326 39, 326 38

Abstract:

An improved, scalable CPLD device has a two-tiered hierarchical switch construct comprised of a Global Switch Matrix (GSM) and an even number of Segment Switch Matrices (SSMs). An even number of Super Logic Blocks (SLBs) are coupled to each SSM. Each SSM and its SLBs define a segment that couples to the GSM. Each SLB has a relatively large number of inputs (at least 80) and can generate product term signals (PTs) that are products of independent input terms provided from the SSM to the SLB inputs. Some of the product terms generated within each SLB are dedicated to SLB-local controls. Each SLB has at least 32 macrocells and at least 16 I/O pads which feedback to both to the local SSM and the global GSM. 100% intra-segment connectivity is assured within each segment so that each segment can function as an independent, mini-CPLD. Each SSM has additional lines, dedicated for inter-segment (global) communications.

Robert DeHart - Mason OH
Robert D. Simon - Gahanna OH

Assignee:

Airtrim, Inc. - Springfield OH

International Classification:

B65H 2000

US Classification:

226 974, 406 92, 406152, 406153

Abstract:

A continuous supply of scrap material from a papermaking or converting process is transferred by a venturi inducer system including a housing surrounding a tubular intake duct which defines with the housing an annular air chamber connected to receive pressurized air from a motor driven blower. The housing has a tapered or frusto-conical portion connected to a tapered material outlet duct and which cooperates with the inner end of the intake duct to define an annular nozzle opening. Long adjustable bolts connect the intake duct to the housing outboard of the housing and provide for externally adjusting the intake duct axially for precisely selecting the area of the nozzle opening to optimize the air flow through the nozzle opening for pulling and transferring the material while minimizing the electrical power required to operate the blower motor.

Appl. No.:

10/839359

Inventors:

Robert J. Simon - Bellbrook OH, US
Kenneth C. Harrington - Beavercreek OH, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 2/085

US Classification:

347 76

Abstract:

An improved continuous ink jet print station includes a drop generator with a jet array and a drop charging assembly. The drop charging assembly includes a substrate with a first side facing the jet array, and one or more resistive heater elements placed on the substrate aligned with the jet array. The resistive heater elements are discontinuously disposed on portions of the substrate. One or more one charging electrodes are disposed on the first side. The continuous ink jet print station includes a power source for powering the resistive heater elements to heat the substrate to a temperature sufficient to prevent condensation of fluid on the first side.

International Classification:

B41J 2/175

US Classification:

347 7, 347 73, 347 14

Abstract:

An inkjet printer having an array of nozzles from which ink drops are emitted further includes a mechanism adapted to detect fluid levels in an ink supply tank to the inkjet printer while the printer is in idle mode, and shut down the printer when ink usage exceeds a predetermined volume.

Appl. No.:

12/796729

Inventors:

Joseph E. Lill - Waynesville OH, US

Robert J. Simon - Bellbrook OH, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 29/393

US Classification:

347 19

Abstract:

A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch () with a first color with a plurality of printheads () at a first pressure and with a first pixel fill coverage. A second color patch () is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.

Filed:

Dec 14, 1998

Appl. No.:

9/211517

Inventors:

Robert J. Simon - Bellbrook OH
Bruce A. Bowling - Beavercreek OH

Assignee:

Scitex Digital Printing, Inc. - Dayton OH

International Classification:

G01D 1518

US Classification:

216 27

Abstract:

The present invention provides for an improvement in the removal of fluid from an ink jet printhead. A branched structure having multiple groups of branches creates a flow geometry, with each group of branches having a connecting trunk. The fluid flow is then able to be directed from each plurality of branches down the connecting trunk. Pressure drops at the branching nodes are minimized by directing the flow from the combined branches down the connected trunk. Expansion losses at the branching nodes are minimized by funneling down the flow at the branching nodes, with the trunk having a narrower channel than the combination of the joined branches.
