Appl. No.:

09/408783

Inventors:

Thomas K. Hebert - Groveland MA

Assignee:

Agfa Corporation - Wilmington MA

International Classification:

G03B 158

US Classification:

2423327, 2423481, 2425861, 2425866

Abstract:

A media receiving cassette is disclosed for use in a system in which a web of media is transferred from a supply cassette to the receiving cassette. The media receiving cassette includes a housing, a rotatable core, and a spring biased grasping mechanism. The housing includes first and second opposing ends, and at least one of the ends includes a generally circular track therein that includes an extended portion which extends radially outwardly. The rotatable core is coupled to the first and second opposing ends of the housing such that an axis of rotation of the core extends through each of the first and second ends. The spring biased grasping mechanism is attached to the rotatable core via at least one spring. The grasping mechanism includes a tracking member that engages the generally circular track such that the grasping mechanism is permitted to move radially outwardly away from the core when the tracking member is positioned in the extended portion of the generally circular track to thereby permit the media to be received in the core. The grasping mechanism is permitted to move radially inwardly toward the core when the tracking member is positioned in a location other than in the extended portion of the generally circular track.

Abstract:

The present invention provides a method and apparatus for applying a coating material onto a print substrate mounted on a plate cylinder of a printing press. The method comprising: delivering a supply of the coating material to a distributive surface of an ultrasonic horn, the distributive surface controlling a flow of the coating material to an active edge of the ultrasonic horn, and atomizing the coating material at the active edge of the ultrasonic horn and directing the atomized coating material onto a surface of the print substrate. The present invention also provides a multi-purpose ultrasonic acoustic coating/cleaning system for applying a coating material onto, and cleaning the coating material from, a print substrate.

International Classification:

B41F 3500

US Classification:

101424, 101425

Abstract:

The present invention provides a method and apparatus for cleaning a coating material from a surface of a print substrate mounted on the plate cylinder of a printing press using an ultrasonic acoustic cleaning apparatus. The method comprises: applying a cleaning solution onto a surface of the print substrate, rotating the plate cylinder to displace the print substrate under an ultrasonic acoustic cleaning apparatus to dislodge a coating material from the surface of the print substrate, and removing the dislodged coating material and the cleaning solution from the print substrate using a vacuum system.

US Classification:

1014011, 101477, 101481, 101485

Abstract:

A method for aligning a printing plate, prior to imaging, on a platesetter includes the steps of: determining a leading edge of the printing plate; feeding the printing plate by the leading edge onto punch equipment resident on the platesetter; centering the printing plate on the platesetter along the leading edge; punching one or more notches along the leading edge of the printing plate according to a predetermined punch configuration; securing the leading edge and a trailing edge to a support surface of the platesetter with respect to registration pins located on platesetter; determining a location of a vertical edge of one of the notches, the vertical edge defined as being perpendicular to the leading edge; and determining a location with respect to the vertical edge of the one notch for transferring an image onto the printing plate.

Inventors:

Thomas K. Hebert - Groveland MA, US

International Classification:

G01N 21/86

US Classification:

25055936

Abstract:

An edge detection system that locates the edge of a printing plate on a platesetter includes: first scratches aligned in a first direction on a support surface; a groove machined into the support surface where the groove includes two surfaces. One surface is reflective and has second scratches aligned in a second direction perpendicular to the first direction of the first scratches. The system also includes: an edge detection light source to provide a beam for scanning along a length of the support surface on a path coincident with the groove; a sensor to sense a reflected edge detection beam from the support surface; and a controller to analyze the reflected beam, where the beam reflected from the first scratches is 90 degrees out of phase with the beam reflected from the second scratches and where the beam reflected from the first scratches is high in intensity relative to the beam reflected from the second scratches.

Abstract:

Systems and methods for optical path protection for distributed antenna systems are provided. In one embodiment, a system comprises a hub and at least one node located remotely from the hub. The hub is coupled to the node by first and second fiber paths, the first fiber path comprising an uplink fiber and a downlink fiber, the second fiber path comprising an uplink fiber and a downlink fiber. The node is coupled to the downlink fibers of the first and second fiber paths via an optical combiner, and is further coupled to the uplink fibers of the first and second fiber paths via an optical splitter. The node further monitors a signal quality of a downlink optical signal and communicates to the hub information indicative of the signal quality. The hub switches communications between the hub and the node from the first to second fiber path based on the information.
