Abstract: A conveyor for moving objects along a path is comprised of a plurality of spaced-apart rollers that define the path of the conveyor. The upper edges of the rollers are aligned to define the surface of the path. Two spaced-apart side rails having inward-facing surfaces define two side boundaries of the path. A barrier assembly is disposed within a gap in one of the side rails for facilitating loading and unloading of objects onto the conveyor from one side of the conveyor. The barrier assembly is comprised of a mounting plate mounted to the conveyor and a barrier pivotally mounted to the mounting plate. The barrier has a wall section generally aligned with the inward-facing surface on one of the side rails. The barrier is movable between a first position wherein the wall section is elevated relative to the upper edges of the roller and a second position wherein the wall section is disposed below the upper edge of the rollers.

Abstract: The present invention provides a spray arm assembly comprised of a tubular member rotatable about a fixed axis. The tubular member has an internal passage and a central axis extending a length of the tubular member. A nozzle assembly is attachable to an end of the tubular member and fluidly communicates with the internal passage of the tubular member. The nozzle assembly is comprised of an insert attachable to the tubular member in a predetermined position. A nozzle body has an aperture therein defining a spray orifice. The nozzle body is mountable to the insert in one of a plurality of positions wherein the spray orifice has an orientation based upon a position of the nozzle body relative to the insert. A fastening means is provided for fastening the insert and the nozzle body together in one of the plurality of positions.
