Abstract: An orthopedic trialing instrument may include a shaft extending from a first end to a second end, a handle coupled to the shaft, and a first interbody trial disposed on the first end. In various embodiments, the first interbody trial may include a first bone screw indicator configured to visually represent a corresponding bone screw trajectory. In some embodiments, a double-sided orthopedic trialing instrument may include a first interbody trial on a first end and a second interbody trial on a second end. In various embodiments, each of the first interbody trial and second interbody trial may have at least one bone screw protrusion configured to visually represent a corresponding bone screw trajectory. In some embodiments, a plurality of orthopedic trialing instruments having differently sized interbody trials may be provided as a kit.

Abstract: The lifting system includes a lifting portion and a hinging portion for lifting a conveyor The lifting portion is fixed to a structure and extends from the structure to mate with the conveyor at a lifting point. The lifting portion moves the conveyor vertically upward and downward at the lifting point with no horizontal movement at the lifting point. The hinging portion is pivotally connected to the conveyor at a conveyor pivot and extends from the conveyor to engage the structure. The hinging portion is further pivotally connected to the structure to allow for controlled movement in an arced path at the conveyor pivot of the conveyor. The controlled movement of the conveyor along the arced path at the conveyor pivot varies the angular position of the conveyor and maintains the position of the conveyor over the transportable container as the lifting portion moves the conveyor vertically at the lifting point.

Abstract: A moving gate discharge system designed to prevent product-breakage while discharging particulate products, particularly non-free flowing and inter-engaging particulate products, in a more uniform flow from a receptacle having a moving bottom, is disclosed. The system includes an endless circulating feeder mounted across the discharge of the receptacle with its lower end portion oscillating upwardly and downwardly and traveling at a horizontal speed more rapid than that of the product on the moving bottom of the receptacle. Product-progressing finger assemblies are mounted in transverse rows on the feeder, spaced distances equal to the longitudinal distance the feeder moves during one period of vertical movement of the lower end portion thereof, and located such that each will be disposed directly below the lower end portion of the feeder when the latter reaches the lower portion of its downward movement.
