Abstract: Currency processing systems, coin processing machines, and methods of sorting coins with disk-type sorters are presented herein. A currency processing system is disclosed which includes a housing with an input area for receiving coins and receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The coin processing unit includes a rotatable disk for imparting motion to coins, and a sorting head adjacent the rotatable disk with shaped regions for guiding moving coins to exit channels which sort and discharge coins through exit stations to the coin receptacles. The sorting head includes a plurality of localized inserts that are fabricated from a material or materials which is/are distinct from the material of the sorting head. Each localized insert has a distinct shape and is readily removably attached at a distinct one of various predetermined locations on the sorting head.

Abstract: A door system for a transit vehicle provided with a door opening has a full height sliding door for covering and uncovering the door opening, and a threshold which is disposed within the sliding door when the sliding door is closed. The threshold is positioned at substantially the elevation of the floor. A retention mechanism is attached to the threshold, the retention mechanism is activated when the trap door is in the deployed position to engage the trap door and release the sliding door so that when the sliding door is opened, the threshold is retained to fill a gap between the trap door and the platform. When the trap door is in the stowed position, the retention mechanism disengages the trap door and engages the sliding door so that the threshold moves with the sliding door and does not interfere with street level street level boarding.

Abstract: The invention provides a drive nut bracket for attaching a drive nut to a driven component to move the driven component. The drive nut is moved by a rotating drive screw. The drive nut bracket provides rotational constraint and linear constraint of the drive nut. It has a nut engaging portion pivotally connected to the base. The nut engaging portion has at least one slide surface portion for sliding engagement with the nut so that the nut may slide relative to the nut engaging portion in a direction substantially perpendicular to the pivot axis. The pivot and the slide surface accommodate misalignments of the drive screw and the driven component. The nut engaging portion includes at least one drive force receiving surface portion facing generally along the axis of the drive screw to provide the linear constraint of the drive nut relative to the driven component.

Abstract: A powered operator for sliding plug doors mounted on a movable carriage mounted overhead of an opening in the side wall of a transit vehicle, said doors including a single electric prime mover driving dual helical drives, each operating a door hanger attached to a single door panel over and away from said opening and for moving said carriage out of said side wall pocket. Door hangers used provide controlled deflection of door panels when in a fully open position. Drive linkages lock door panels when in a plugged position. The operator also provides guidance for the lower edge of said door panels during plugging and unplugging operations. Control elements and a central controller provides sequential door panel movement into and out of a pocket in the transit car side wall.
