Properties of the laser treatment are selected so as to change the physical state of each surface. Ellipsometry measurements are made in a region of the first surface before application of the laser beam treatment to the second surface, so as to obtain a physico-chemical characterization of the first surface. Both the laser beam application and the ellipsometry measurement are conducted under generally similar working conditions, so that the change of the physical state of each surface produced by the laser treatment can be controlled in a real time, in-situ, rapidly and nondestructively.Type: GrantFiled: January 16, 1998Date of Patent: June 13, 2000Assignee: Societe de Production et de RecherchesInventors: Pierre Boher, Marc Stehle

Patent number: 6073469Abstract: A high security lock includes a shackle having two ends and a lock body having openings for receiving the ends of the shackle. A latch in the lock body has a catch movable into engagement with the shackle for securing at least one end of the shackle in the body. The latch is releasable to allow the one end of the shackle to move clear of the body to open the lock. The shackle is made of a shape memory effect alloy having a characteristic that its yield strength increases when work is impressed on it, so that cutting or breaking the shackle with common tools is more difficult and time consuming than with other shackle materials. The lock thus provides a level of security substantially superior to conventional locks.Type: GrantFiled: June 7, 1995Date of Patent: June 13, 2000Assignee: Nitinol Technologies, Inc.Inventor: Gerald J. Julien

Patent number: 6073470Abstract: A device for locking the wheel of a vehicle to prevent unauthorized movement of the vehicle. The device is particularly suited for use with trailers and other such vehicles that are often left at unguarded or remote locations. The device has a mounting member suitable for mounting on the underside of the vehicle frame or body and a locking member suitable for placement under one of the wheels of the vehicle. A connecting member interconnects and is hingedly connected to both the mounting and locking members. To allow use on a variety of vehicles, the connecting member is adjustable to vary its length and it adjustably connects to the mounting member. The hinged connections of the connecting member to the mounting and locking members allows the device to be placed in a collapsed configuration when it is not in use. A retaining pin is used to hold the device in the collapsed condition.Type: GrantFiled: December 29, 1998Date of Patent: June 13, 2000Inventors: Larry D. Burnitzki, Lorraine L. Burnitzki

Patent number: 6073471Abstract: A wire-crimping device detects if an electrical terminal is stuck to a crimper after crimping, thereby effectively eliminating deformed terminals. Electrical wire-crimping device (1) has a ram (42) slidably mounted to a housing (4). A reflection light sensor (60) is mounted to the housing (4), and a pathway (80) that communicates with a wire-crimping member (40) is located in the ram (42). If an electrical terminal (30) should stick to crimpers (50, 52) after crimping, and if the wire-crimping member (40) mounted to the ram (42) rises, a wire depressor (54) will also rise, and an upper end of the wire depressor (54) will block the pathway (80). As a result, the light emitted from the reflection light sensor (60) will be reflected and detected by a light sensor, and it will be electrically detected that a defective part has been produced.Type: GrantFiled: July 7, 1999Date of Patent: June 13, 2000Assignee: The Whitaker CorporationInventors: Shigeru Naka, Hiromi Tanaka

Patent number: 6073474Abstract: A work roll bending system for profile control of continuous metal strip during rolling which is especially useful for retrofitting an existing rolling mill absent such feature to provide it with roll bending capabilities. The advantage of the system is its compactness in the vertical direction which facilitates its positioning between housing posts of the rolling mill where space in the vertical direction is often limited. Bending wings for exerting bending forces to work roll chocks with use of hydraulic cylinder and piston assemblies extend from the chocks in an intermeshing manner to allow wings from top and bottom work roll chocks to occupy the same horizontal plane without interference during at least some roll gap settings. That bending wing arrangement also allows for elimination of a "layer" of hydraulic cylinder and piston assemblies which also reduces space requirements in the vertical direction.Type: GrantFiled: June 24, 1999Date of Patent: June 13, 2000Assignee: Danieli United, a divison of Danieli CorporationInventor: Robert William Dittmar
