Abstract: A dipper door trip assembly includes a dipper, a dipper door pivotally coupled to the dipper, a linkage assembly including a sliding latch bar disposed at least partially in the dipper door, and a latch keeper coupled to the dipper. The latch keeper includes a roller that engages and disengages the latch bar.

Abstract: An article supply device includes a plurality of storage units in which a plurality of types of articles are respectively stored, a plurality of supply paths, a plurality of open/close stoppers that control the supply amounts of articles for each supply path, a plurality of partition/passing-through members that form gaps depending on the types of the articles, between the surfaces of the supply paths and the plurality of partition/passing-through members, and a driving unit that allows the supply paths and the partition/passing-through members to relatively move each other.

Abstract: A mechanical linkage for a power machine includes first and second horizontal shafts extending sideways along respective first and second axes. First and second links are operably coupled to the respective first and second horizontal shafts. The links convert actuation of operator input devices of the power machine into rotation of the horizontal shafts about their axes. First and second valve actuators convert rotation of the respective first and second horizontal shafts into actuation of respective first and second spools in a hydraulic valve of the power machine.

Abstract: A system and method for servicing a rotor of a generator are presented. The system includes a carriage for carrying the rotor. At least one carriage steering device are arranged on the carriage for steering the carriage when traversing along a removal skid during servicing the rotor. The carriage steering device is attached to the carriage in a way that it is accessible from above the carriage. The carriage steering device is adjustable such that a center of the carriage aligns to a center rail of the removal skid when traversing along the removal skid during servicing the rotor.

Abstract: Substrate transferring apparatus includes a first-hand mechanism and second hand mechanism. The first-hand mechanism includes a first lower arm, first upper arm, first-hand having a tip end portion as a first substrate holding portion, and first driven mechanism to rotate the first-hand with rotation of the first upper arm. The first-hand mechanism so the first substrate holding portion movable by rotations of the first lower arm, first upper arm, and first-hand between a contracted and extended positions. The second-hand mechanism includes a second lower arm, second upper arm, second-hand having a tip end portion as a second substrate holding portion, and second driven mechanism to rotate the second-hand with rotation of the second upper arm. The second-hand mechanism so the second substrate holding portion movable by rotations of the second lower arm, second upper arm, and second-hand in sync with the first substrate holding portion between a contracted and extended positions.
