International Classification:

A61B 500

US Classification:

600585

Abstract:

Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.

International Classification:

D21G 300

US Classification:

162281, 162272, 1525651

Abstract:

An apparatus for doctoring a roll surface including a pivot bar adapted to be mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is held downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcrum in a direction urging the doctor blade against the roll surface.

International Classification:

D31F 1/12

US Classification:

162281, 162280, 152565, 118413

Abstract:

A doctor blade holder comprises upper and lower mutually spaced jaw components defining a slot. A doctor blade is removably retained in the slot, and nozzles in one of the jaw components are arranged to direct fluid under pressure into the slot for application to the doctor blade.

International Classification:

B41F 9/10

US Classification:

101169000

Abstract:

A reciprocating doctor is provided for doctoring the cylindrical surface of a roll rotating about a first axis. The doctor includes a doctor back with a blade holder carrying a doctor blade. The doctor back has journals aligned on a second axis parallel to the first rotational axis of the roll. The journals are rotatably supported in sleeve bearings, and the sleeve bearings are in turn supported by diaphragms spaced along the second axis. The sleeve bearings are fixed axially on their respective journals, and the diaphragms have hub portions surrounding and fixed relative to the sleeve bearings, and peripheral portions surrounding the hub portions and fixed relative to a support structure. The diaphragms are configured to resiliently accommodate reciprocating movement of their hub portions and associated sleeve bearings relative to their peripheral portions and associated support structure. A first operating mechanism serves to rotate the doctor back about the second axis, and a second operating mechanism serves to impart reciprocating movement to the journals and their sleeve bearings along the second axis.

Appl. No.:

11/101349

Inventors:

Robert Reid - Charlton City MA, US

International Classification:

B05C 1/08

US Classification:

118261000, 118413000

Abstract:

A doctor blade holder has a top plate having a rear portion overlying a base structure and a front portion projecting forward from the base structure. Blade support members are carried by and cooperate with the front portion of the top plate to define forwardly open slots for receiving the doctor blade. A hinge is interposed between the rear portion of the doctor blade and the base structure. The hinge has a body portion defining a fulcrum about which the top plate pivots relative to the base structure, and has forwardly and rearwardly projecting integral flanges arranged respectively to underlie the top plate and overlie the base structure. The doctor blade holder has means for securing the forwardly projecting flanges to the top plate and for securing the rearwardly projecting flanges to the base structure.
