  • Patent number: 8262908
    Abstract: A rotary filter is provided with greatly expanded filter media area within the flow stream of material to be filtered due to use of a series of cylindrical filter cartridges consisting of a core and cylindrical filter media that are attached to and within a rotary disc, thus providing much greater filter area within the size constraints of the rotary disc and the flow channel. This allows removal of contaminating material in the flow stream. The retaining methods used for these cartridges restrains their movement within the flow stream thus allowing backflushing by reversing flow direction and venting the backflush material. The attachment and construction further allows easy removal and replacement of filter media and cartridges.

  • Patent number: 8182677
    Abstract: Known tank flanges have a main filter which has a filter housing with an inlet and an outlet, and a first connecting duct for connecting the main filter to a feed unit. The filter housing is integrated in the tank flange, and filter fabric is inserted into the filter housing and the filter housing is closed off by a filter cover. The inlet of the filter housing is connected to the pressure side of a feed unit and the outlet leads to an internal combustion engine. A disadvantage is that, in order to exchange the filter fabric, the large-area filter cover must be opened, as a result of which a large amount of fuel vapor is dissipated to the atmosphere. In the case of the tank flange according to the invention, the exchangeability of the main filter is simplified by virtue of the main filter being embodied as a filter cartridge. It is provided according to the invention that the inlet of the main filter extends into the first connecting duct of the tank flange and therein forms a sealed connection.

  • Patent number: 8052867
    Abstract: A filter apparatus has a housing, an inlet port on one side of the housing and an outlet port on an opposed side of the housing. Sheet media is disposed in the housing having a first opening through the sheet media. Also dispersed in the housing is a bag media comprising an enclosed bag with a second opening into the bag. The first opening and the second opening are connected in fluid communication with each other and the sheet media is disposed before the bag media in the direction of flow through the housing so that both media are mounted inside the housing. Some fluid entering the inlet passes through both openings and through the bag media and into the outlet, and other fluid entering the inlet passes through the sheet media and then to the outlet.

  • Publication number: 20110244098
    Abstract: An improved system for filtering particulate matter from a liquid in a brewing pot. The improvement includes a filter assembly positioned about a drain tube. The filter assembly has a screen member surrounded by a shield member. The shield member is positioned between the drain tube and the particulate matter separated from the liquid. The bulk of the liquid, located in a top portion of a reservoir bypasses the screen member and drains through a drain reservoir and the drain tube. After removing the shield member, the remainder of the liquid drains through the screen member or filter and into the drain reservoir preventing the particulate matter from being carried through to a fermentor.

  • Patent number: 8012349
    Abstract: Methods and devices are provided for preparing and separating biological analytes. In one embodiment, one or more filtration devices or filter plate wells can be formed by clamping a filter sheet between first and second plates having at least one connecting cavity. First and second moveable core pins positioned on opposed sides of the sheet can be moved to remove portions of the sheet. A molten plastic can be injected to fill the volume between the cores and cavities and to form a liquid-impermeable sleeve wall or walls, each being separately sealed at the bottom to the perimeter of the sheet portion, each having liquid permeable regions of said removed and sealed sheet portion, and each remaining open at the top. Various exemplary configurations for filtration devices or filter plate wells are also disclosed.

  • Patent number: 8007668
    Abstract: A device for dialysis of a sample includes a sample chamber formed by a gasket and dialysis membranes affixed to each side of the gasket in facing relationship. A housing supports the dialysis membranes and gasket. An air chamber causes the device to float in a generally upright position when the device is immersed in a dialysate. An access port is provided through the gasket and between the dialysis membranes. The access port is accessible from outside the housing and in communication with the sample chamber such that a dispensing end of a dispensing device can be inserted through the access port to dispense sample into the sample chamber.

  • Patent number: 7997421
    Abstract: A filtering apparatus includes a pot-type filter housing (10), a filter element (28) accommodated in the housing, a holding mechanism (38) disposed in the filter housing (10) to removably fix the filter element along its longitudinal axis, and a sealing device (60) that seals between a lid (20) of the filter housing (10) and the filter element (28). The holding mechanism (38) is provided with cooperating holding elements embodied on the interior face of the filter housing (10) as well as on the filter element (28). The filtering apparatus dispenses with the need for O-seals that are known in prior art and extend in a radial direction between the filter element and the filter head as a housing lid because the sealing device (60) encompasses at least one sealing edge (62) or sealing surface placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied it by the holding mechanism (38).

  • Patent number: 7997423
    Abstract: A cooking oil container has a filter cup retained at the upper end thereof. The filter cup retains a planar circular filter at the lower end and a seal between the filter holder and the bottom of the filter cup prevents oil from overflowing around the circumference of the filter holder to avoid the filter. The filter cup is spaced from the inner walls of the container to allow air to escape from the bottom of the container. The top of the container has a grip ring and the inverted top is useable as a drip tray for the filter cup while oil is being poured out of the container.
