Patent number: 7186947Abstract: A method for monitoring the processing of a workpiece includes directing an incident laser beam onto the workpiece and measuring a signal emitted from the workpiece. At least two signals are generated by a detector based upon the emitted signal. A workpiece processing quality is determined based upon the ratio of the two output signals and a magnitude of one of the two outputs.Type: GrantFiled: March 31, 2003Date of Patent: March 6, 2007Assignee: Hypertherm, Inc.Inventors: William J. Connally, Kenneth J. Woods

Patent number: 6947802Abstract: Apparatus, systems, and methods for monitoring the processing of a workpiece that includes directing an incident laser beam onto the workpiece and using an optical detector for measuring a signal emitted from the workpiece as a result of the incident laser beam. The detector generates at least two signals based upon the optical signal. The method also involves use of a light source monitor in determining workpiece processing quality based upon the quotient of the two outputs as well as a magnitude of one of the two quotients.Type: GrantFiled: March 31, 2003Date of Patent: September 20, 2005Assignee: Hypertherm, Inc.Inventors: Tate S.

Publication number: 20040164058Abstract: A metal jet cutting system, which includes a jetting heat, a heater and a power source, is used for modifying a workpiece. The jetting head includes a crucible and an inlet for receiving a feed stock of a conductive material. The heater melts the conductive material in the crucible to provide a conductive fluid, which exits the jetting head via an outlet. The power source, which is in electrical communication with the conductive fluid, increases the temperature of the conductive fluid. The conductive fluid is applied to the workpiece to modify the workpiece.Type: ApplicationFiled: February 20, 2004Publication date: August 26, 2004Applicant: Hypertherm, Inc.Inventors: Nicholas A. Sanders, Richard W. Couch, Yong Yang, Zhipeng Lu, Robert C. Dean, Kenneth J. Woods, Charles M. Hackett, John Sobr, William J. Connally

Patent number: 5126621Abstract: A flashlamp provides a ruggedized yet simple-to-manufacture construction capable of operating at high average output power over a long life. The flashlamp construction includes a glass tube (12) with an electrode assembly (24) detachably secured to each end. The electrode assembly includes an end cap (26) to which an electrode support (28) is attached, with a first end (32) of the electrode support protruding inside of the glass tube, and a second end (44) of the electrode support protruding outside of the glass tube. The electrode support (28) is made from a suitable electrical conductor. An electrode (34) is threaded onto the first end of the electrode support (28) without the use of brazing or other attachment techniques that might introduce impurities. An electrode lug (36) is attached to or near the second end of the electrode support, outside of the glass tube, and provides a means for making electrical contact with the electrode (34).Type: GrantFiled: January 24, 1991Date of Patent: June 30, 1992Assignee: Maxwell Laboratories, Inc.Inventors: Richard G.
