US Patent:

6533268, Mar 18, 2003

Filed:

Jul 27, 2001

Appl. No.:

09/916993

Inventors:

Lloyd A. Williams - Mahopac NY
Joannes N. M. deJong - Suffern NY
Matthew Dondiego - West Milford NJ
Michael J. Savino - Tappan NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B65H 702

US Classification:

271228

Abstract:

A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a much lower power, and lower cost, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.

US Classification:

271228

Abstract:

A sheet registration system, especially for printers, with a lower cost and lower mass system for sheets deskewing, and optionally also compatibly providing transverse registration repositioning of the sheets. Mechanisms are disclosed which need only one main drive motor to drive both of the two spaced apart sheet feeding nips, together with a much lower power, and lower cost, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet.

Appl. No.:

10/392718

Inventors:

Michael Savino - Staten Island NY 10309

International Classification:

A61M 500

US Classification:

600 7, 604173

Abstract:

The present invention is a seed implantation apparatus comprising a cartridge with an array of chambers having a plurality of hollow needles inside chambers, which can hold one or more radioactive seeds. The seed implantation apparatus also comprises pistons for each of the hollow needles and a plate located behind the pistons with a rod and a mechanical trigger, wherein said actuation causes said plate to move said pistons into said needles. The present invention also includes a method of using the seed implantation apparatus. The apparatus can be used in connection with brachytherapy and has particular utility in connection with simultaneously injecting multiple radioactive seeds into the prostate.

International Classification:

B65H 702

US Classification:

Abstract:

An apparatus and method for registering and deskewing a sheet along a sheet path. A pair of drive spheres are located in the sheet path. When a sheet enters the nips formed by the spheres the sheet is driven until it is sensed by a sensor. The drive spheres are driven by a pair of wheels which allow the spheres to rotate about any axis through their center and parallel to the plane of the sheet. The spheres are driven such that the sheet is side registered and deskewed as it is moved along the sheet path. Constant feedback from the sensors to the drive controller allows the sheet to be registered in a very short distance and has the added benefit of self compensation for wear of the drive components. The wide registration and deskewing latitude of the device allows for the use of relatively inexpensive and low accuracy sheet drives preceding the device.
