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.

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.

Patent number: 7012538Abstract: A method for monitoring the condition of a heating element involving installing the heating element in a location and setting the initial composition Ci of the material as a reference baseline at an initial time Ti corresponding to said installation of the heating element. Data is then collected reflecting the subsequent composition Cs of the heating element material after a subsequent time Ts at the installed location and any change in the material composition of the heating element between Ti and Ts is monitored. An alarm is sent when the change reaches a threshold value indicating a possible failure condition. According to one embodiment, an impedance monitor is provided that calculates and compares impedance at the required levels of accuracy to determine changes in material composition. The impedance monitor, or portions thereof can be embedded within a microcontroller for increased portability and functionality.Type: GrantFiled: July 16, 2003Date of Patent: March 14, 2006Assignee: MRL IndustriesInventors: Kevin B.
