To create a method of this type it is now provided that the temperature (27) is regulated during operation such that a sensor (28) senses the temperature (27) of the evaporator (25) and transmits it to a regulation unit which correspondingly supplies a heating element (24) with the energy necessary and by which a required pressure (34) of the liquid (8) supplied to the torch (6) is regulated so that an approximately constant temperature (27) of the evaporated liquid (8) is provided for a cutting process.Type: GrantFiled: August 30, 2006Date of Patent: June 21, 2011Assignee: FRONIUS International GmbHInventors: Alexander Eder, Heribert Pauser, Florian Silbermayr, Alexander Speigner

Patent number: 7723700Abstract: A vapor delivery system for delivering a steady flow of sublimated vapor to a vacuum chamber comprises a vaporizer of solid material, a mechanical throttling valve, and a pressure gauge, followed by a vapor conduit to the vacuum chamber. The vapor flow rate is determined by both the temperature of the vaporizer and the setting of the conductance of the mechanical throttle valve located between the vaporizer and the vacuum chamber. The temperature of the vaporizer is determined by closed-loop control to a set-point temperature. The mechanical throttle valve is electrically controlled, e.g. the valve position is under closed-loop control to the output of the pressure gauge. In this way the vapor flow rate can be generally proportional to the pressure gauge output. All surfaces exposed to the vapor from the vaporizer to the vacuum chamber are heated to prevent condensation.Type: GrantFiled: December 9, 2004Date of Patent: May 25, 2010Assignee: Semequip, Inc.Inventors: Thomas N. Horsky, Robert W. Milgate, III

Patent number: 7680399Abstract: Systems and methods for producing and delivering vapor are disclosed. A vaporizer tank containing a liquid may be heated such that liquid within the tank is heated and vapor generated. The flow of this vapor to a destination may then be regulated. Embodiments of the present invention may control the temperature of this liquid such that a saturated vapor condition is substantially maintained in the vaporizer tank. The vaporizer tank is coupled to a mass flow controller which regulates the delivery of the vapor to downstream components. By substantially maintaining the saturated vapor condition within the vaporizer tank the pressure of vapor at the mass flow controller can be substantially maintained and a stable and consistent flow rate of vapor achieved.Type: GrantFiled: February 7, 2006Date of Patent: March 16, 2010Assignee: Brooks Instrument, LLCInventors: Daryl Buchanan, Faisal Tariq, Hai Mei, Stuart Tison
