  • Patent number: 11137294
    Abstract: Systems and methods are provided to detect a failed thermocouple. A temperature in a gas path of a gas turbine engine may be measured, where the temperature is based on a signal generated by a thermocouple during a startup of the gas turbine engine and/or during an idle period that immediately follows the startup, and the thermocouple protrudes into the gas path. A failure of the thermocouple may be detected if the temperature is determined to be less than a threshold temperature.
    Type: Grant

  • Patent number: 5405181
    Abstract: A safety apparatus to be mounted on a chassis of a dump vehicle having a dump back movable between a rest position and a dump position. The safety apparatus has a guide member attached to the vehicle chassis to define a closed track. There is a safety prop pivotally attached to the dump back. At the bottom of the safety prop a wheel or the like is attached and is received by and engages the guide member. There is a locking member to retain the safety prop and thus the dump back in a fixed position relative to the guide member when the back is raised to the dump position. The locking member acts to prevent downward movement of the back.
