Abstract: A crop residue distributor assembly for a combine harvester. The crop residue distributor includes a straw distributor hood, below which a number of adjustable vanes is arranged on both sides of a longitudinal median plane of the crop residue distributor assembly. A flow divider is arranged adjacent to the longitudinal media plane with diverging walls. The flow divider is coupled to the vanes in such a way that the flow divider moves together with the vanes when the vanes are adjusted.

Abstract: A switchgear having bus transfer current switching capability by a turn and twist mechanism that includes a contact system for electrical current conduction and bus transfer switching is provided. The contact system has fixed and movable contact assemblies. Each contact assembly includes main contacts and arcing contacts. The arcing contacts are for bus transfer switching. The movable contact assembly includes a current path pipe and an end piece. The current path pipe is a cylindrical pipe, and the end piece is a rectangular block. The movable contact assembly includes a movable main contact provided on the rectangular block, and a movable arcing contact provided at the end of the cylindrical pipe on a portion about the periphery. During engagement, the cylindrical pipe turns about a first axis to bring the contact assemblies proximal to each other, and twists about a second axis for engagement of the main contacts.

Abstract: A switchgear having a turn and twist mechanism. The switchgear has a contact system for electrical current conduction and bus transfer switching. The contact system has a fixed contact assembly and a movable contact assembly. The turn and twist mechanism drives the movable contact assembly for engagement/disengagement of the movable contacts with the fixed contacts. The turn and twist mechanism comprises a cylindrical pipe and a driving assembly. The driving assembly comprises a driving base, a floating carrier and a driving pin arrangement, for driving the cylindrical pipe for the engagement/disengagement. The driving base drives the floating carrier for turning the cylindrical pipe about a first axis, and drives the driving pin arrangement for twisting the cylindrical pipe about a second axis.
