Abstract: A sprinkler assembly can include a water inlet and a nozzle assembly. The nozzle assembly can include a nozzle tube having a nozzle positioned at the downstream end of the nozzle tube. The sprinkler assembly can include a user replaceable wear disc at least partially surrounding the nozzle tube. A deflector assembly can be connected to the nozzle assembly and can include a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle. The deflector assembly can include a cage having one or more arms connected to the distribution plate and extending from the distribution plate toward upstream end of the nozzle tube. The deflector assembly can include an upstream collar portion connected to the at least one arm and having one or more load surfaces configured to contact the wear disc, wherein the wear disc is configured to bear at least a majority of a weight of the deflector assembly.

Abstract: A dual knife-edge transfer conveyor for transporting small articles from one conveyor to a second conveyor, upper sections of the conveyors being in approximately the same plane, the conveyors being driven in the same transport direction and following each other immediately in the transport direction and thus forming a gap between the two conveyors, the dual knife-edge transfer conveyor comprising: a dual knife-edge plate member, an endless transfer belt, the transfer belt revolving about the dual knife-edge plate member, a transfer conveyor frame, the dual knife-edge plate member being attached to an upper section of the frame, the dual knife-edge plate member also having a pair of edges, each of the edges having a small radius, the frame being positioned in between the two conveyors such that the dual knife-edge plate member lies in approximately the same plane as the two conveyors, the dual knife-edge plate member further having a length slightly smaller than the gap formed between the two conveyors, defle
