Abstract: In accordance with an embodiment, described herein are a system and method for providing a promoted track display for use with a media content or media streaming environment. A media device, operating as a client device, can receive and play media content provided by a media server. An advertisement server can be used to determine advertisements or promoted content to be delivered to the client in connection with the provided media content. One or more promoted tracks, for example songs, music, or other sponsor content, can be surfaced or otherwise displayed at a user interface of the media device via visuals or display queues that are playable upon user-click or other form of selection. Display queues that include promoted tracks can be used to increase promoted track inventory and provide an engaging advertisement format for use by media content partners, for example, music promoters.

Abstract: An oil distribution system for machinery such as a vacuum pump is disclosed. The system features an auxiliary oil pump integrally mounted adjacent to one end of the vacuum pump's drive shaft. The drive shaft drives the oil pump and has a longitudinal passage extending substantially along its length in communication with the outlet from the oil pump. Oil ports, positioned at points along the drive shaft adjacent to bearings supporting the drive shaft, extend from the passage. Lubricating oil, drawn from a reservoir by the oil pump, is pumped into the passage. The oil exits the passage via the oil ports and lubricates the bearings. The oil passes into the pump cylinder where it provides an oil seal between the piston and cylinder wall. Either a rotary vane pump or a gerotor-type pump is preferred as the auxiliary oil pump.
