Abstract: A steering lever mechanism for a mower vehicle includes a lever assembly and a base which is fixed to the mower vehicle for mounting the lever assembly to the mower. The lever assembly includes a pivot assembly and a lever portion. The lever portion is pivotably mounted to the pivot assembly for rotation about a longitudinal axis between an inboard position and an outboard position. The pivot assembly is also pivotably mounted to the base for rotation of the pivot bracket portion and the lever portion about a transverse axis between a rear position, an intermediate neutral position and a forward position. A rotation-measuring device is associated with the base and the pivot assembly for measuring the forward and rear rotation of the lever assembly.

Abstract: A dual trip manifold assembly (TMA) includes an isolation valve assembly having a first valve configured to receive a flow of fluid from a hydraulic system fluid supply. The first valve is configured to channel the flow of fluid to at least one hydraulic circuit. The isolation valve assembly also includes a second valve configured to receive the flow of fluid from the at least one hydraulic circuit. The second valve is further configured to channel the fluid flow to a trip header. The first valve and the second valve are synchronized to each other such that rotation of one valve causes a substantially similar rotation in the other valve.

Abstract: Combination trip and throttle valve steam controls for a steam turbine include manual controls to actuate the trip mechanism and shut the turbine down and a trip/reset, with a single control to regulate the steam delivered to the turbine and to reset the trip mechanism to provide simplified and reliable controls.

Abstract: A gas turbine engine has variable vanes in the rear compressor that are automatically scheduled to their optimum position for proper engine operation by a closed loop primary engine control system in response to selected engine operating conditions. A failure in the engine control system may cause the variable vanes to be locked in a position which degrades the engine aerodynamics to a dangerous level. An emergency controller is connected to schedule the position of the variable compressor vanes in an open loop manner in response to changes in the power lever when a failure of the primary engine control system occurs.
