A filter assembly for use with a surgical suction tool for removing fluid and debris from a surgical site includes a conical filter element with a plurality of orifice arrays spaced along the length of the conical body with successively decreasing orifice diameters. The filter element includes an annular flange at the mouth of the filter element that is clamped between a container and a cap. The container includes conically tapered wall to define a radial space between the container and the filter element to permit fluid flow around the filter element and through the container to an outlet tube fitting. A cap covers the mouth of the container with a threaded interface defined between the cap and the container. The threaded interface includes a dual pitch triple lead thread with a coarse lead-in pitch and a fine trailing pitch.

A handling bar for laminated or film supports, such as paper, is disclosed, including a hollow tubular body provided with an inner cavity and an outer side surface, a plurality of through holes, arranged on the tubular body to put the inner cavity in contact with the outer side surface. The handling bar also includes at least one connection to a compressed air source or a suction device, where the connection is shaped for the inflow of compressed air or to suction air into the cavity and at least one filtering element arranged inside the tubular body where at least at one portion of the holes filters the air passing between the inner cavity and the holes.

A product including a bottle with a mouth; a drink inside the bottle, the drink including a version of an alcoholic drink, where there is no alcohol or there is alcohol at a concentration by volume less than 1.5%; a pourer attached to the mouth and having a flow channel, a check valve, an air-vent channel and a filter, where the flow channel and the check valve allow via the same a flow of the non-alcoholic drink towards outside the product, the air-vent channel allows air to pass inside the bottle, and the filter produces a filtration of the air passing inside the bottle via the air-vent channel, the drink being any of a non-alcoholic drink, an alcohol substitute drink, a low alcohol drink, an alcohol free drink, or a de-alcoholized drink. Also, a method for extending the lifetime of a non-alcoholic drink, related to making the drink.

Articles and methods involving filter media are generally provided. In certain embodiments, a filter media has a design and/or comprises one or more layers that enhances its efficiency and/or performance.

The present invention relates to a hollow filter candle (1) which has, via impregnation of the inside with a catalyst solution, a concentration gradient of catalyst metals from the inside to the outside across the wall thickness thereof. The present invention furthermore relates to a method for producing a filter candle (1) according to the invention and the use of the filter candle (1) according to the invention for exhaust gas cleaning, in particular in waste incineration plants.

A pourer for pouring a liquid from a bottle having a solid main body; a flow channel at the main body; a check valve at the flow channel; an air-vent channel at the main body; and a filter at the air-vent channel. The flow channel and the check valve are configured for allowing via the same a flow of the liquid from inside the bottle towards outside the bottle under the action of gravity when the bottle is turned to a pouring position for pouring the liquid; the air-vent channel is configured for allowing air from outside the bottle to pass inside the bottle via the air-vent channel during the flow of the liquid; and the filter is configured for producing a filtration of the air when the latter passes from outside the bottle to inside the bottle via the air-vent channel. Also, a product includes the pourer.

The electret-treated sheet includes: a core layer (A) which is a porous film containing at least a thermoplastic resin; a surface layer (X) disposed on one side of the core layer (A); and a back surface layer (Y) disposed on the other side of the core layer (A), the surface layer (X) and the back surface layer (Y) each having a charged outermost surface, wherein the electret-treated sheet has a water vapor permeability coefficient of 0.1 to 2.5 g.Math.mm/m.sup.2.Math.24 hr; the core layer (A) has a pore aspect ratio of 5 to 50 and an average pore height of 2.5 to 15 μm; the surface layer (X) and the back surface layer (Y) each have a thickness of 5 to 200 μm; and the surface layer (X) includes a heat seal layer (B) including the outermost surface, wherein the heat seal layer (B) has a melting point of 50 to 140° C.

Gasoline Direct Injection (GDI) engines require gasoline particulate filters (GPFs) as a key component of the emissions control system to reduce particulate emissions. GPFs are known to have poor initial performance, with performance increasing after the filter develops a cake. This poor initial performance make it impossible to accurately assess vehicle emissions performance at the mileage requirements for vehicle certification. Compositions and methods are disclosed to improve filtration efficiency in a fresh or low mileage GPF.

An object of the present invention is to provide an adsorbent, a filter medium, and an air filter that have good aldehyde removal performance that undergoes little deterioration over time, where the adsorbent is one in which an inorganic porous medium supports at least an amine-based compound and a compound having a sulfide group as a functional group.
