Abstract: A roller for a conveyor system is provided. The roller may include a body, an axle, a first end connector, and a spring. The body may include a first end and a second end opposite the first end. The axle may be disposed in the body extending from the first end to the second end. The first end connector may be configured to interface with the body on the first end. The first end connector may protrude at least partially past the first end. The spring may be configured to interface with the body and the first end connector. The spring may be configured to provide a restoring force to the first end connector when depressed.

Abstract: An injector mount system (30) is provided for mounting an injector (22) to an exhaust flow conduit (21) in an exhaust treatment system (10). The injector (22) includes a housing (32) having an open end (46) that mounts an orifice/nozzle (38). The injector mount system (30) includes a boss (62) fixed to the exhaust flow conduit (21), and an end cap (44) of the injector (22) that is attached to the housing (32), closing the open end (46) and securing the orifice/nozzle (38) in the open end (46). The boss (62) and end cap (44) include mating flanges (60,64) that define a non-threaded connector for securing the injector (22) to the exhaust flow conduit (21). The mating flange (60) of the end cap (44) being formed as a unitary part of the end cap (44), and the mating flange (64) of the boss being a unitary part of the boss (62).

Abstract: A self supporting head mounted harness for mounting a respirator mask on the face of a user, the harness including a harness body having a material stiffness sufficient to enable the harness to be retained and self supported on the head of a user independent of whether or not the mask is attached to the harness.
