Appl. No.:

12/105603

Inventors:

John L. Herman - Huber Heights OH, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 2/175

US Classification:

347 85

Abstract:

A constant flow valve mechanism for use in an inkjet printer includes a valve. A first port, a second port, and a third port are in fluid communication with each other through the valve. A portion of the valve is moveable and associated with the first, second, and third ports to produce a change in fluid impedance between the first port and the second port and the first port and the third port such that the fluid impedance between the first port and the second port changes at the same rate and in an opposite direction as that of the fluid impedance between the first port and the third port.

Appl. No.:

8/648206

Inventors:

John Lawrence Herman - Huber Heights OH

Assignee:

Heidelberg Finishing Systems Inc. - Dayton OH

International Classification:

B65H 3900

US Classification:

270 5226

Abstract:

A collator (10) collates folded signatures (30). A conveyor (12) of the collator (10) moves a plurality of support saddles (20). The support saddles (20) receive and support the signatures (30) with their folds extending in a direction perpendicular to a movement direction (18) of the support saddles. A feed mechanism (40) feeds a signature (30) down toward a respective support saddle (20) as the conveyor (12) moves the support saddles. The signature (30) falls vertically toward the respective support saddle (20). An air handler (66) draws air down, vertically relative to the respective support saddle (20) to minimize air resistance acting against the signature (30) being fed to the respective support saddle (20).

US Classification:

271270

Abstract:

The present invention relates to a sheet handling apparatus having a hopper drum (1) for receiving individual signatures (23) from a feed tray, the hopper drum being equipped with at least one set of signature seizing grippers (16). A hopper drum surface element (13) revolves counter to a direction of rotation (7) of the hopper drum (1) upon reversal of direction (33) of the signatures (23). A seizing element (26) is assigned to the direction reversal position (38) of the signatures (23).

International Classification:

B65H 2012

US Classification:

226 95

Abstract:

A rotatable drum is disclosed for securing thereto various sizes of sheets of film by a partial vacuum. The drum includes a cylindrical body and first and second circular end blocks connected for closing the body. The drum is mounted for rotation about its central axis. The first end block defines concentrically therethrough a central passageway, connected to a source of partial vacuum so that the drum may be partially evacuated. The cylindrical body defines on its outer surface a plurality of parallel, identical grooves extending circumferentially about the body. A plurality of holes also extend through the body, each of the holes opening on the outer surface into one of the grooves. Importantly, the cross-sectional area of each hole is approximately equal to the cross-sectional area of each of the grooves, and no porting or valving is provided for the drum interior to close unneeded holes. The first block further defines a plurality of auxiliary passageways, each of the auxiliary passageways opening at a first end through the inner face of the block and connecting at a second end with the central passageway.

Abstract:

A blade holding device is provided for use with a blade and a cylinder, the cylinder having a longitudinal recess defined in the periphery thereof parallel to the axis of the cylinder. First and second wedge members are fittable within the recess, each wedge member having an inner face and an outer face. A plurality of spring members is included, along with a resilient strip for holding the spring members in relative positions. The wedge members are insertable within the recess such that the resilient strip holding the spring members is disposed adjacent the outer face of the first wedge member. The blade is disposed between the resilient strip and a wall of the recess. Relative movement of the wedge members is performed by a bolt threadingly engaged with an end of the second wedge member and held in relative position with respect to the cylinder, whereby the blade is clamped between the first wedge member and the recess wall.
