Patent number: 8279072Abstract: A method for determining a maintenance interval for a consumable part and/or for equipment containing a consumable part obtains a plurality of measurements of temperature of the consumable part, receives each of the measurements at a totalizing unit, correlates each of the measurements to one of a plurality of temperature subranges, accumulates for each of the subranges an amount of time the measurements of temperature were correlated to each of the subranges, determines a total time by aggregating the accumulated time for each subrange with a weighting function, and generates a signal to prompt a maintenance event when the total time equals or passes a runtime setpoint. In supplement to or in alternative to the above, the method also correlates a subrange of two sequential measurements, indexes a breakpoint register if the correlated subranges are different, and generates a signal to prompt a maintenance event when a value of the breakpoint register equals or passes a breakpoint setpoint.Type: GrantFiled: March 16, 2009Date of Patent: October 2, 2012Assignee: MRL Industries Inc.Inventors: Kevin B. Peck, Bjorn W. Larsson

Patent number: 7825672Abstract: Methods to determine an instantaneous resistance value of an electric circuit and a measurement system to determine an instantaneous resistance value of an electric circuit are disclosed. Exemplary embodiments of the method measure an in-situ instantaneous voltage of the circuit and an in-situ instantaneous current of the circuit and calculate the instantaneous resistance. Optional temperature measurement can be included in the method and the calculated instantaneous resistance related to the measured temperature. The method can be applied to phase angle fired loads and to zero-cross (time proportioned) loads.Type: GrantFiled: June 19, 2006Date of Patent: November 2, 2010Assignees: MRL Industries, Inc., Sandvik Intellectual Property ABInventors: Kevin B. Peck, Noel Johnson, Björn Å. Larsson, Pontus K. H. Nilsson

Patent number: 7335864Abstract: Heating element assemblies, heating furnaces incorporating heating element assemblies, methods to form heating element assemblies, methods to form heating furnaces and methods to reduce a magnetic field in a bifilar coil are disclosed. The heating element assembly includes two components, each component formed from heating element wire. The two components are spatially positioned and electrically arranged, relative to each other, so that an electrical current applied to the heating element assembly simultaneously travels through the two components in opposite directions.Type: GrantFiled: May 31, 2006Date of Patent: February 26, 2008Assignee: MRL Industries, Inc.Inventors: Kevin B.

Patent number: 7293986Abstract: The present invention provides a heat treating process chamber having a housing with a flow passage in communication with a vestibule assembly. The vestibule assembly includes an outer ring with a first groove and an inner ring with a second groove. The first groove is formed in an axially inwardly facing surface of the outer ring. The first groove has a portion open in a radially outer direction and an axially inner direction. The second groove opens in an axially inner direction and is formed in an axially outwardly facing surface of the inner ring. The first and second grooves form a passageway when they are in an axially superimposed relationship. The first groove forms a radially outwardly open end and the second groove forms an axially inwardly facing end of the passageway. The passageway communicates with the flow passage thereby allowing passage of a temperature adjusting medium.Type: GrantFiled: May 6, 2003Date of Patent: November 13, 2007Assignee: MRL Industries, Inc.Inventors: Kevin B. Peck, Mike D. Soliday, Jim Sanches
