Abstract: Systems are provided for an axle housing for a vehicle. In one example, system includes a differential housing comprising a modular Salisbury style center section comprising tube mounts configured to receive tube assemblies via a press fit.

Abstract: A substantially mineral oil-free aqueous composition useful to produce a dry lubricant film comprising water; a silicone oil, a vegetable oil or a mixture thereof; at least one waxy film-forming material selected from at least two of the following three groups: (a) saturated C.sub.10 -C.sub.24 aliphatic monohydric alcohols, (b) saturated C.sub.10 -C.sub.24 aliphatic monocarboxylic acids, and (c) saturated or monounsaturated C.sub.10 -C.sub.24 aliphatic primary amides; and an anionic surfactant; nonionic surfactant or mixture thereof capable of stably dispersing the oil and film-forming mixture in the water.

Abstract: A powder feed hopper includes a housing which mounts a porous plate adapted to support particulate powder material and receive an upwardly directed flow of fluidizing air to form an air-entrained fluidized bed in the housing above the porous plate. In order to improve fluidization, a baffle plate is mounted beneath the porous plate in the path of the pressurized air discharged from one or more air nozzles to create a circulating flow of air-entrained particulate powder material within the fluidized bed in which the flow moves upwardly along the wall of the housing and then inwardly and downwardly toward the center of the porous plate. Additionally, stirrer blades are located immediately above the porous plate to create turbulence and reduce the formation of concentrated channels of air atop the porous plate.
