摘要： A test fixture to test for possible leakage past a seal between adjacent portions of two test panels. The test panels are supported on a housing in edge-to-edge relation across the open front of a chamber in a housing. The panels are moved toward the open front of the chamber so that the panels seal against the open front. The housing is supported in a cabinet. Liquid is discharged into the cabinet and directed against the seal. The housing has a rear wall which is visible through the cabinet and is constructed to enable viewing into the chamber to see whether the seal has leaked.

摘要： A system and process for controlling an excavation implement during excavation between an above-ground position and a below-ground position. The excavation implement is actuated by use of the engine operating at a target output level. A computer controls the rate at which the excavation implement is moved in a generally vertical direction while excavating earth between the above-ground and below-ground positions. A sensor senses a performance parameter indicative of either engine performance or excavation implement performance as the excavation implement progresses through the earth. The computer modifies actuation of the excavation implement in response to the sensed performance parameter to maintain the engine at the target output level when the engine is subject to variations in loading as the excavation implement moves between the above-ground and below-ground positions.
