摘要： The present disclosure relates to a tumble dryer (1) with a filter arrangement (12) located in a tumble dryer process air flow (21) for removing lint from process air leaving tumble dryer drum. The filter arrangement comprises a first coarse-mesh filter (25) and a second fine filter (27). A first sensor (41) detects a correct positioning of the first filter in the tumble dryer, and a second sensor (33) detects a pressure drop over a process air flow path comprising the second filter. A control arrangement (45) is configured to initiate a disabling operation which disables the fan arrangement (12), if the first filter is not correctly positioned in the tumble dryer or if the pressure drop over the second filter exceeds a predetermined threshold value.

摘要： The challenge of the present invention is to provide a multilayer filter medium whose deodorizing performance after a long-term storage of the filter medium is suppressed from deteriorating and which is superior in deodorizing performance and exhibits low pressure drop. A multilayer filter medium includes three or more nonwoven fabric layers superposed together and has two or more interlayer regions each formed by two adjacent layers of the nonwoven fabric layers, in which a first interlayer region of the interlayer regions contains functional particles A having an average particle diameter of 50 to 100 μm, and a second interlayer region selected from the interlayer regions excluding the first interlayer region contains functional particles B having an average particle diameter of 150 to 500 μm.

摘要： Charged polymeric webs, such as electret webs, include a thermoplastic resin and a charge-enhancing additive. The additives are substituted heterocyclic thiols. The heterocyclic thiol has 2 nitrogen groups and a third group that may be an NH, N—NH2, O, or S group. The substituent group is an aromatic or heterocyclic aromatic group. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.

摘要： An irrigation recirculation system and methods of filtering and cleaning water within the irrigation recirculation system. The system includes an above the ground water source and a fluid flow conduit that conveys the water into a filter element within a basin. The filter element separates solids from the water by causing the water to change direction before continuing on a fluid flow path. The water is then stored and distributed by a self-cleaning storage system that convey the filtered water to sprinkler heads of the irrigation system.

摘要： A biological device that includes a case, an electronic unit, a gas-liquid separator, and an insulating sheet. The case is wearable on a body. The electronic unit is in an internal space of the case. The gas-liquid separator is attached to the case. The insulating sheet is attached to the case. The case has a communicating hole that connects the internal space and an external space of the case along a first direction. The gas-liquid separator and the insulating sheet are disposed apart from each other in the first direction. The gas-liquid separator, the electronic unit, and the insulating sheet overlap each other in a plan view of the biological device in the first direction.

摘要： A filter device is formed by installing an orifice member to the fluid passage of a filter body and avoids being functionally impaired by residue such as shavings generated during the installing of the orifice member. A filter device is provided with a filter body that has a fluid passage; and an orifice member that is installed in the fluid passage. The orifice member is provided with a body that has an orifice, a first flange that is press-fitted into the large-diameter part of the fluid passage, and a second flange that forms a closed trap space between itself and the first flange. A knurling is provided to the outer peripheral surface of the first flange. A knurling is provided to the outer peripheral surface of the first flange. Shavings formed during the installing of the orifice member to the filter body are captured in the trap space.

摘要： A face mask includes a filter body including a composite film. The composite film includes a first layer of a stretched sintered polymeric material, and a second layer of an expanded polymer film secured to the first layer. The face mask includes one or more straps for securing the filter body over the mouth and nose of a wearer. A process for making a face mask includes providing a composite film including a sintered polymeric material adjacent an expanded polymer film, thermoforming the composite film to produce a filter body of the face mask, and attaching one or more straps to the filter body.

摘要： Disclosed is a filtration article comprising a first layer comprising porous PTFE for fluid filtration (e.g., a PTFE membrane), and a second layer comprising strands of fluoropolymer fibers arranged to form a stable knit. The knit layer comprises interlocking regions that are each defined by corresponding sets of at least two interlocking loop portions of the fluoropolymer fiber strands. In filtration article embodiments, the fluoropolymer fiber strands may be twisted and/or have a rounded outer configuration. The knit layer provides improved dimensional stability as a support layer for the filtration layer and/or as a drainage layer.
