The device comprises a housing comprising at least one hollow spiral element with a conical shape, with separation openings being formed in at least some of the turns of the spiral element, each of the openings communicating with a corresponding separation chamber. Arranged opposite the separation opening is a nozzle, which is intended for compensating for the mass and centrifugal moment of the fluid medium. A guide element around which a flow passes is mounted on the wall of the nozzle. The cross-sectional area and the radius of each successive turn is selected from the condition for maintaining an estimated value for the centrifugal moment of the substance to be purified. The method consists in that a flow of medium to be purified is spun by the above-described device. Contaminating components in each turn are positioned by coaxial layers.

    Abstract: One exemplary embodiment can be a vessel. The vessel can include a body, an inlet, and an impermeable impingement plate. The body may include a substantially cylindrical structure orientated substantially horizontally, and first and second heads coupled at opposing ends of the substantially cylindrical structure. Generally, the body forms an interior space, and a lower portion of the body forms a trough having a length and a width. The inlet can communicate with the interior space of the vessel. Typically, the impermeable impingement plate has an impingement surface. The impermeable impingement plate may have a first side and a second side extending substantially the length of the trough. The first and second sides may be substantially parallel and spaced apart across at least a portion of the width of the trough.

  • Publication number: 20110290118
    Abstract: In a vaporized fuel treatment apparatus a partition wall member is housed in an inner cap, and a gas-liquid separation chamber and a fuel adsorption chamber are defined on either side of the partition wall member. Further, a partition plate is provided on an open end of the inner cap. Wall portions are formed respectively on the partition wall member and the partition plate, and a conduction passage is defined in the fuel adsorption chamber by these wall portions. As a result, air containing vaporized fuel can be guided to every corner of the fuel adsorption chamber. Further, a through hole is provided in a central portion of the partition wall member, and therefore liquid fuel is prevented from flowing into the fuel adsorption chamber even when a fuel tank is tilted.

  • Publication number: 20110277638
    Abstract: Gas anti-diffusion assemblies are designed to slow, but not to block, the diffusion of a gas from or to an enclosed space to or from an open space, e.g., to slow the diffusion of air into or out of the housing for a hard disk drive from or out to the exterior of the housing. The assemblies typically have a laminate structure, i.e., are constructed of individual layers adhered or otherwise joined to one another in a stacked arrangement. The assemblies typically comprise alternating layers of polymeric film and adhesive with a mesh layer sandwiched or otherwise positioned within the assembly, and optionally comprises one or both of a filter layer and an absorbent layer.
