An inlet for receiving the mixture opens into a separation chamber tangentially with a cylindrical side wall and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is located in an opposing second end wall. A debris passage extends through the cylindrical side wall and oriented so that the radial velocity of the particles within the separation chamber directs the particles through the debris passage. The debris passage leads to a particle collection chamber in which the particles accumulate. Unlike prior separators that relied on the tangential velocity of the particles, the present apparatus utilizes the greater radial velocity to drive the particles from the separation chamber into the particle collection chamber.

  • Patent number: 7160469
    Abstract: Many areas in the world already suffer shortages of water, and others will suffer from it in the coming years. Therefore more efficient water sweetening is essential for our survival on this planet. The most commonly used water sweetening methods are: Reversed osmosis, distillation, electrodyalisis, and partial freezing. However, these methods suffer from low efficiency and high energy consumption, thus making them significantly more expensive than naturally obtained water. The present invention describes a system & method for efficient and low energy sweetening of water, based on borderline fast fluctuation between liquid to gaseous state and back, by using centrifugal forces to make water droplets fly at a high speed, so that they evaporate for a split second, the salt is separated, and they condense again. The present invention tries to make the process energy-efficient by enabling the use of lower speeds and smaller droplet sizes and solving various problems involved with that.

A hollow cylinder having an outer radius, “Router”, is positioned at the second end of the chamber and centered on the axis. Cross electric and magnetic fields (E×B) are established in the chamber that are configured to send ions of relatively high mass on trajectories having a radial apogee, rapogee, that is greater than the cylinder's outer radius (r>Router). After reaching apogee, these ions lose energy and strike the cylinder where they are collected. Low mass ions are placed on small radius helical trajectories and pass through the hollow cylinder.

  • Patent number: 6905029
    Abstract: A method, system, apparatus, and article of manufacture provide a cross-flow migration classifier capable of separating particles. The classifier provides a channel through which a sample, having one or more particles, passes in a first direction, wherein the channel comprises two or more walls that are permeable to a flow of fluid. A cross-flow enters the channel through one of the permeable walls and exits through another of the permeable walls. An imposed field is applied in a second direction that is counter to the cross-flow and having an orthogonal component to the first direction. The imposed field causes one or more of the particles to migrate at a first velocity opposite and/or equal to a second velocity of the cross-flow. The particles that migrate opposite to the cross-flow are continuously discharged from the cross-flow migration classifier.

  • Patent number: 6875343
    Abstract: A dual direction bypass valve allows a transmission filter to function whether or not it is placed in the vehicle transmission correctly. The filter includes a front and rear valve bodies separated by an end cap, and each having a spring and disk. When the filter media is clogged during normal forward flow, the fluid pressure on the rear valve body disk compresses the spring, opening an aperture in the end cap, allowing the fluid to pass from the front valve body through the rear valve body to the outlet, bypassing the filter media. If the transmission filter is placed in the engine backwards, the fluid pressure compresses the spring of the front valve body and opens up apertures in the end cap, such that the fluid flows through the apertures and the front valve body, bypassing the rear valve body and the filter media, to exit the filter.

  • Patent number: 6846411
    Abstract: A filter adapter for removing metallic particles from fluid. The adapter is cylindrical in shape and includes an attachment insert for mounting the adapter between a source in a fluid flow system and a conventional filter. The adapter has a ring shaped magnet held in the housing of the adapter by magnet holders. The adapter has a plurality of perforations in the top and bottom for the flow of unfiltered fluid from the fluid source, through the adapter, and to the conventional filter. The attachment insert is hollow so as to allow filtered oil to flow back from the conventional filter to the fluid system the adapter is attached to.

  • Patent number: 6821790
    Abstract: A method of separating a cell-containing sample into a substantially cell-depleted portion, and a cell-containing portion comprising at least one of a stem cell, a lymphocyte, and a leukocyte comprises a step in which the sample is received in a vessel with at least one flexible wall. In another step, an additive and particles are added to the sample, wherein the additive substantially binds to the at least one of the stem cell, lymphocyte, and leukocyte, and the particles and wherein the particles substantially bind to the at least one of the stem cell, lymphocyte, and leukocyte, and the additive, thereby producing a cell-containing network. In a further step, the network is separated from the substantially cell-depleted portion by applying a magnetic force.

  • Publication number: 20040206678
    Abstract: A filter device according to the present invention comprises: a filter portion having a fluid outlet at its axis, and a fluid inlet in a position away from the axis, in which a fluid containing particles is supplied at a predetermined flow speed from the fluid inlet to cause a swirl, particles are moved outward in a centrifugal state and the fluid from which the particles are separated is discharged from the fluid outlet, and the particles separated by slowing down the swirl are allowed to sink; and a settlement portion in which the particles that settle in the filter portion are allowed to settle. Thus, a fluid containing particles is supplied at a predetermined flow speed to cause a swirl, the particles are separated by a centrifugal force caused by the swirl and allowed to sink and settle, and the fluid from which the particles are separated is discharged. A large amount of particles can be allowed to settle and be reliably removed in a short time with this small-sized and simple device.

  • Patent number: 6802404
    Abstract: A hydraulic fluid flow passage has a controlled restriction disposed within the passage. The restriction includes a first filter, a second filter and a plurality of particles disposed between the two filters. The particles are either dielectric particles or they are magnetizable particles. The dielectric particles create an electro-rheological fluid between the filters and the magnetizable particles create a magneto-rheological fluid between the filters. The arrangement for the dielectric particles is controlled by an electric field and the arrangement for the magnetizable particles is controlled by a magnetic field.

  • Publication number: 20040188335
    Abstract: A removable particle collector for an apparatus which separates metal particles from lubricating oil. A valve assembly has a bore that provides a passage into the reservoir from outside. A valve element is normally biased against a valve seat to close the bore. A plug has a stem which when inserted into the valve assembly bore forces the valve element away from the valve seat. A portion of the stem is magnetized to attract ferromagnetic particles in the reservoir. A plurality of balls rotatably project from a surface on either the valve assembly or the plug and are received in a plurality of locking grooves in the other of the valve assembly and the plug to secure those components together. The balls are lubricated by fluid from the reservoir and can rotate to reduce wear which could loosen the components.
