    Abstract: A device and method for tempering sections of hot-formed and/or press-hardened metal components is disclosed having a support structure and a work head, the work head having at least one contact element consisting of an electrically-conductive material, for heating sections of a metal component using a flow of heat. Electrodes for resistively heating the contact element are connected thereto, and to a current source. A hot-formed and/or press-hardened metal component is first provided, and at least one contact element mounted on a work head is heated to a temperature greater than a target temperature to which a section of the metal component is to be heated. A contact surface of said contact element then comes into full-surface contact with the metal component section to be heated, with a predetermined pressing force, such that the metal component is heated to a target temperature in at least some sections by a flow of heat. The contact element is thus heated using resistive heating.

An impedance spectroscopy system for monitoring ischemic mucosal damage in hollow viscous organs comprises a sensor catheter and an impedance spectrometer for electrically driving the catheter to obtain a complex tissue impedance spectrum. Once the catheter is in place in one of a patient's hollow viscous organs, the impedance spectrometer obtains the complex impedance spectrum by causing two electrodes in the tip of the catheter to inject a current into the mucosal tissue at different frequencies, while two other electrodes measure the resulting voltages. A pattern recognition system is then used to analyze the complex impedance spectrum and to quantify the severity of the mucosal injury. Alternatively, the complex impedance spectrum can be appropriately plotted against the spectrum of normal tissue, allowing for a visual comparison by trained personnel.

  • Patent number: 8455784
    Abstract: A method of welding two or more workpieces employing a motion-controlled electrode that reduces temperature and residual stresses at a workpiece-to-electrode interface is disclosed. During a first period of time, a first electrode force is applied to the workpieces to be welded, and a weld current is applied that causes heating of an associated workpiece-to-workpiece faying surface, the first electrode force being applied at a first electrode stroke. A temperature of the faying surface indicative of a weld nugget formation thereat is determined, and in response thereto the electrode force is reduced to a second level during a second period of time while maintaining a constant electrode stroke. During a third period of time, the electrode force is further reduced to a third level while simultaneously reducing the electrode stroke to a second level. Welding is stopped after the third period of time, resulting in a weld joint having reduced residual stresses and reduced likelihood of stress crack formation.

  • Patent number: 8309874
    Abstract: A method and apparatus for heating or cooling a fluid. An inlet conduit coupled to a plurality of distribution nozzles in fluid communication with a channel at the periphery of the apparatus. An insert and a sleeve cooperatively define a thin gap, in fluid communication with the channel, through which the fluid flows. Thermal inserts near the thin gap generate heat flux into or out of the fluid, which exits through an outlet conduit.

  • Patent number: 8293172
    Abstract: A method of dispensing a volatile material includes the steps of providing power to a volatile material diffuser having a diffusion element and operating the diffusion element for a first period of time, wherein the diffusion element is continuously activated and deactivated during the period of time at a first duty cycle having a first on time and a first off time. Still further, the method includes the step of operating the diffusion element for a final period of time, wherein the diffusion element is continuously activated and deactivated during the final period of time at a final duty cycle having a final on time and a final off time. The first duty cycle is less than about 100% such that the first off time is greater than about 0 seconds and the final duty cycle is about 100% such that the final off time is about 0 seconds and wherein the final period of time begins after the first period of time has finished.

  • Publication number: 20120261386
    Abstract: A track rail heating assembly that is adapted to position a heater element in spaced relation proximate to a surface of a track rail of a railroad. The assembly includes at least one heating element, and a housing that is operable to at least partially surround the heating element while positioning the heating element near to track rail. The hood positions the heating element relative to the rail section such that a gap exists between the heating element and the rail section. As the heating element does not contact the rail, the heating element cannot form an electrical by-pass for signals passing through the rail section. The assembly further incorporates a flexible barrier that at least partially isolates a side surface of the track rail from ambient conditions to reduce heat loss.
