A flow suppression device adapted to be connected to a high pressure fluid system includes an outer flow containment member of a porous and flexible construction. The outer flow containment member has an upstream end and a downstream end opposite the upstream end. The upstream end includes an inlet opening adapted to receive a flow stream of pressurized fluid from the high pressure fluid system and the downstream end being substantially closed. The flow suppression device also includes a primary inner flow containment member of a porous and flexible construction contained within the outer flow containment member. The primary inner flow containment member has an upstream end with an inlet opening adjacent the inlet opening of the outer flow containment member and a downstream end opposite the upstream end of the primary inner flow containment member.

A thermal pad is adapted to be placed in physical contact with a patient and to receive temperature controlled fluid from a thermal control unit. The temperature controlled fluid circulates through the thermal pad and controls the patient's temperature. The thermal pad includes first and second sheets that are sealed together about their periphery to define a fluid chamber there between. A fluid inlet and fluid outlet are fluidly coupled to the fluid chamber. In some embodiments, a filter sheet is sandwiched between the first and second sheets and arranged such that fluid entering the fluid inlet must pass through the filter sheet before exiting out of the fluid outlet. A plurality of bonds may be included that seal the first and second sheets together at a plurality of locations. In some embodiments, a non-sheet filter is positioned within the fluid chamber and filters the circulating fluid.

Water filter with self-rinsing capability that includes filter housing, hollow cartridge core, and mesh filter. The filter housing includes a hollow housing with top and drain openings, a top cover with inlet and outlet ports, a one-way pressure valve, and a drain tap that includes a rod, an opening and closing knob that is connected to the rod, and an opening and closing barrier with passageway that is connected to the rod. The cartridge comprises of a tube with inlet and outlet passageways, and spray pipes with spray nozzles, and enables water to flows from the tube into the spray pipes and outside into the filter housing through the nozzles. The mesh filter has a shape of a hollow cylinder that is worn on the tube in a gap between the tube and the spray pipes.

A method adapts a filter medium to predefinable parameters, such as electrostatic charge, flow-rate behavior, dynamic pressure behavior or differential pressure behavior, fraction filtration efficiency and preservation of a constant quantity and quality of fluid additives. At least one of these parameters is adapted by the targeted influencing of the surface energy of the filter medium (18).

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

An object of the present invention is to provide a filtering device which makes it possible to obtain a chemical liquid having excellent performance and enables filter media to have sufficiently long pot life. Another object of the present invention is to provide a purification device, a chemical liquid manufacturing device, a filtered substance to be purified, a chemical liquid, and an actinic ray-sensitive or radiation-sensitive resin composition. A filtering device according to an embodiment of the present invention has a first filter unit including a first filter, which satisfies at least one condition selected from the group consisting of following conditions 1 to 3, and a housing accommodating the first filter and a second filter unit including a second filter different from the first filter and a housing accommodating the second filter, in which the first filter unit and the second filter unit are independently disposed in a pipe line through which a substance to be purified is supplied. Condition 1: the filter has a filter medium including two or more layers containing materials different from each other. Condition 2: the filter has a filter medium including two or more layers having different pore structures. Condition 3: the filter has a filter medium including one layer in which different materials are mixed together.

Methods, apparatuses and systems for providing an apparatus such as, for example, a gas detecting apparatus are disclosed herein. An example apparatus may comprise: a manifold defining a gas flow channel that is configured to convey a gaseous substance from a gas inlet on a surface of the manifold; and at least one integrated flow regulating component comprising a filtering element that is configured to filter the gaseous substance, wherein the filtering element is disposed adjacent an orifice that leads to an interior channel of the integrated flow regulating component, and wherein the filtering element is disposed upstream with respect to the orifice.

A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.

A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame. The filter media is operable to filter the wastewater of waste material as the wastewater passes therethrough. A top opening is disposed on a top portion of the frame. A bottom of the top opening is located above the tank outlet and below the tank inlet. When the filter media is not clogged, a level of the wastewater remains below the top opening. When the filter media is clogged, the level of the wastewater rises until the wastewater flows over the top opening.

A device is provided that provides an unbiased filtration effect and an effect of removing captured substances through backwashing by causing a fluid to uniformly pass through a filter element over the entire length in an axial direction at the time of backwashing so as to efficiently rotate a captured-substance removal tool in a filtration unit 1 which includes the captured-substance removal tool 20 axially supported inside the tubular filter element 2 to be rotatable.
