A film-shaped aperture array includes a first principal surface and a second principal surface opposed to each other and a plurality of apertures penetrating the first principal surface and the second principal surface. A projection projecting from the second principal surface in a normal direction of the second principal surface is provided in at least one region in contact with three or more of the plurality of apertures in a part of the second principal surface, when viewed in plan from the normal direction of the second principal surface.

A filter element, in particular for treating fluids in the form of diesel fuel, has a filter medium (14) through which the fluid can flow. The filter medium (14) contains at least one active substance having antimicrobial properties.

A screen includes a framework of a first material having one or more openings therethrough defining a fluidic filter, and a substance of a second material positioned within the one or more openings in the framework and configured to be removable from the framework during an electrochemical reaction.

A blood processing filter for removing undesirable components from liquid containing a blood component or blood, comprises a sheet-shaped filter element, and a container that includes an inlet-side container element and an outlet-side container element that are disposed to clamp the filter element, and has an internal space separated by the filter element into an inlet space and an outlet space. The filter element includes a pair of filtering surfaces disposed on the inlet space side and the outlet space side, and an end surface along a periphery of the pair of the filtering surfaces, and the inlet-side container element and the outlet-side container element are provided with a gripper that clamps and compresses outer edge portions of the pair of filtering surfaces, and adheres to the end surface with melt resin, and a part of the container is provided with a steam-permeable portion having steam permeability.

The invention relates to a method for adapting a filter medium to predefinable parameters, such as electrostatic charge, flow-rate behaviour, dynamic pressure behaviour or differential pressure behaviour, fraction filtration efficiency and preservation of a constant quantity and quality of fluid additives. Said method is characterised in that at least one of the aforementioned parameters is adapted by the targeted influencing of the surface energy of the filter medium (18).

A liquid filter assembly comprising a filter subassembly is inserted within an elongated tubular filter body, enclosed by a pair of end caps. The filter subassembly includes a plurality of filtration discs placed onto a tubular core and inner support member. A disc aperture is provided concentrically through each filtration disc. An outer filter support member and a central filter support member support each filtration disc. The outer filter support member engages with an interior of the elongated body and an end wall engages with the disc perimeter. The central filter support member engages with an exterior of the inner support member and an end wall engages with the peripheral edge about the filtration disc aperture. Fluid passes through the first end cap orifice, continuing through the inner support member, transferring flow through the filtration discs, returning through the inner support member, and exiting the opposite end cap orifice.

A system and method for positioning a pill to be ingested by a user in a field of view of an image acquisition camera. The method includes the steps of determining a desired location of the mouth of a user in a field of view of an image acquisition camera, determining a current position of a pill to be ingested by the user in the field of view of the image acquisition apparatus, and indicating on a display a movement to be made by the user to move the pill towards mouth of the user.

A multi-layer liquid purification element includes a liquid-permeable top layer and a liquid-impermeable base layer. The base layer has a suction port for drawing-in liquid through the liquid purification element. At least the top layer and the base layer are connected to one another by a liquid-impermeable connection. At least one separate insert is disposed between the top layer and the base layer. A method for producing a liquid purification element, a device for extracting a liquid additive for exhaust-gas purification from a tank and a motor vehicle are also provided.

A fluid filter formed of microbially-produced cellulose, preferably formed into a web of cellulose fibers in artificial culture of the microbes, then removed from the culture and shaped into a filter. The shaping may include a compression step and may also include an embossing step. Methods of culturing and forming the filter are also disclosed.

Device (50) for filtering air intended to supply an air system of an airborne, rail-bound or automotive transport vehicle, characterized in that it comprises a porous three-dimensional structure (52) comprising at least one portion intended to be in contact with said air to be filtered, referred to as exchange portion (53), said exchange portion (53) comprising at least one adsorbent material in the form of particles selected from carbon, a zeolite, a metal organic framework and mixtures thereof, said adsorbent particles being bound by a binder, said binder comprising at least one material selected from the group formed of boehmite, hydrated aluminas, transition aluminas and mixtures thereof.
