Title: Method for performing registration audits.
Inventor: PERRY L JOHNSON
IPC: G06Q10/10
Filed: 2001-12-31
Abstract: A method for standards registrars to improve customer service includes value-added auditing (100) in which auditors describe at least two opportunities for improvement (104) to the client or customer seeking registration.

Patent MX-PA04010427-A (MX)
Title: Stepped cam die.
Inventor: HODJAT YAHYA
IPC: B21D53/28
Filed: 2003-03-05
Abstract: The invention comprises a cam die. The cam die comprises at least one cam ring (20a, 20c). The cam ring comprises a plurality of moveable cam teeth. The cam teeth are moveable on a normal toward an axis of the cam die by a cam actuator (10). The cam actuator has an inside diameter that is less than an outside diameter of the cam ring. As the cam actuator moves parallel to the cam die axis along an outside circumference of the cam ring, the cam teeth are progressively engaged and pressed inwardly toward a work piece (p). The work piece is moved simultaneously with the cam actuator by action of a punch (60) that is concentric with the cam actuator and within the diameter of the cam ring. Each cam tooth is simultaneously engaged with the work piece as the work piece passes. A resilient member returns each cam tooth to a starting position after the cam actuator is withdrawn, allowing ejection of a finished part.
