Abstract: An air filter cartridge for filtering liquids, such as fuel or oil, can be used in a filter assembly. The air filter cartridge has first and second opposite end caps and filter media extending between the end caps. The first end cap has an air channel with an inlet and an outlet to allow for the bleeding of air from the unfiltered side to the filtered side, while minimizing the amount of liquid allowed to bypass the media. Due to the viscosity differences of air versus liquid (e.g. a hydrocarbon such as fuel or oil), a long vent with at least one thin axis impedes liquid flow to a greater degree than air flow through the same vent.

Abstract: Plasma/cell concentrator apparatus and methods are described herein for concentrating constituents from a fluid. Generally, a volume of the fluid may be urged from a first reservoir to a second reservoir through a fluid channel and a volume of desiccant for mixing with the fluid may be introduced to create a mixture. This fluid and desiccant mixture may be passed between the first and second reservoirs until one or more components from the fluid are absorbed by the desiccant. After mixing, the fluid may be withdrawn through a withdrawal channel which is in fluid communication with the fluid channel while preventing the desiccant from passing into the withdrawal channel.
