Abstract: The disclosure describes a flow conditioning device for dampening pulses and improving performance of a compressor. In one approach, a diffuser device includes a housing member having a first end and a second end, the housing member coupled to an outlet of a compressor, and a diffuser member disposed within the housing member. The diffuser member is in fluid communication with a working fluid delivered from the compressor, and includes a core member extending along a longitudinal axis of the diffuser member, and a plurality of flutes extending radially from the core member. In some approaches, the plurality of flutes and an inner surface of the housing define a plurality of fluid channels for delivering the working fluid from the first end to the second end of the housing member. In some approaches, the diffuser member is rotatably coupled to the housing member.

Abstract: A method of assembling a portable compressor package comprises steps of assembling a sub-frame module that comprises the mechanical components of an apparatus for ease of assembly to associated structural modules for minimisation of assembly time and ease of assembly.

Abstract: A running gear for a wagon comprises a cantilever extending away from one end of the wagon, a socket coupled to the cantilever proximate a distal end of the cantilever, a kingpin that rotatably engages the socket about a steering axis of rotation, at least one steering axle coupled to the kingpin for rotatably retaining at least one steering wheel to allow each steering wheel to swivel about the steering axis of rotation and a draw bar coupled to each steering axle to tow and steer the wagon.

Abstract: A segmented labyrinth seal (10) having a windback configuration formed around a rotatable shaft for preventing leakage of oil from a bearing housing having a first face (22) and a second face (23). An exterior cylindrical surface (19) and an interior cylindrical surface (18) extend between the first face (22) and the second face (23). A thread pattern (40) provided on the interior cylindrical surface (18) providing the windback configuration, and configured in a right-hand direction or a left-hand direction. A plurality of profiled teeth (41) form the thread pattern (40) and have first sides (43), second sides (44), and connecting sides (45) extending between the first sides (43) and the second sides (44). Leading edges (47) are formed where the first sides (43) join the connecting sides (45), and trailing edges (48) are formed where the second sides (44) join the connecting sides (45). The first sides (43) and the second sides (44) are slanted toward the first face (22).
