Walter W Duley, Grant Kinsman: Laser surface treatment. Fleit Jacobson Cohn Price Holman & Stern, November 20, 1990: US04972061 (31 worldwide citation)

A method of modifying the reflectivity and emissivity of a surface of a material comprises the steps of irradiating the surface with a beam of coherent pulsed radiation at a power sufficient to generate a surface plasma and scanning said beam across said surface. Successive pulses of radiation are c ...

Kenneth Grant Kinsman, Walter W Duley: Caser seam welding of aluminum alloys. February 23, 1999: US05874708 (9 worldwide citation)

A method of welding aluminum alloy workpieces includes the pretreatment of an area adjacent to the seam of the workpiece followed by irradiation of the area with an infrared laser beam having a diameter equal to or greater than the thickness of the workpieces. Substantial subsurface melting of the w ...

Kenneth Grant Kinsman, Walter W Duley: Laser-welding techniques using pre-heated tool and enlarged beam. Powerlasers, Fried Frank Harris Shriver & Jacobson, September 29, 1998: US05814784 (9 worldwide citation)

A laser processing method establishes initial coupling between the laser beam and workpiece by irradiating an intermediate tool positioned adjacent the workpiece. The tool is more absorptive at the laser wavelength than the workpiece so that the efficiency of energy transfer is increased. Subsequent ...

Walter Bruce Markham, Kenneth Grant Kinsman, Jan Hendrikse, Gordon Robertson: Sample preparation and slide plating apparatus and method. Lerner David Littenberg Krumholz & Mentlik, July 4, 2002: US20020086431-A1

A method of collecting cells from a specimen and plating such cells onto a slide to create a monolayer. A suspension of cells is filtered to remove unwanted material and monitored to determine if a desired quantity of cells are collected. If insufficient cells are present in the filtered sample, add ...
