Abstract: An aerosol-generating system includes a liquid storage portion including housing holding a liquid aerosol-forming substrate and a capillary medium. The housing has an opening. A fluid permeable heater assembly includes an arrangement of electrically conductive filaments arranged to define an air impingement surface. The fluid permeable heater assembly extends across the opening of the housing. The filament arrangement defines a filament opening allowing airflow to pass through. The capillary medium is provided in contact with the heater assembly. The capillary medium is configured to draw the liquid aerosol forming substrate to the electrically conductive filament arrangement. The capillary medium includes a capillary medium opening extending the filament opening through the capillary medium.

Abstract: A valve assembly for a vehicle exhaust system includes a rigid mount structure that is configured to be mounted within an exhaust component that defines an exhaust gas passage. The valve assembly further includes a plurality of flexible members that each extend from a first end to a second end. One of the first ends and second ends of the flexible members is fixed to the rigid mount structure and the other of the first ends and second ends is free to move such that the plurality of flexible members creates a variable restriction to flow through the exhaust component that varies in response to a pressure difference upstream and downstream of the plurality of flexible members.

Abstract: A wire mesh burner plate for use in large, gas burners for large ovens is comprised of spaced-apart wire mesh plates. The spacing between the wire mesh plates defines an air/fuel mixture space. The fuel passes through the lower or first mesh, experiences a pressure drop, mixes with air and passes through a second wire mesh. The gas combusts after passing through the second wire mesh. The fine gauge of the mesh prevents combustion from flowing backwardly into the fuel/air mixture space. Several individual wire mesh burner plates can be flexibly attached to each other such that a very wide space can be covered. Thermal stresses are reduced by being distributed across multiple burners.

Abstract: A device, system and method of mixing two fluids are described herein. A gaseous first fluid is distributed through a distribution zone to a mixing zone by a bundle of pipes parallel to an axis inside which the first fluid is uniformly distributed. A second fluid is uniformly distributed outside the pipes in the distribution zone. The mixing zone is separated from the distribution zone by a pipe-plate supporting the pipes. The pipe-plate has slits or openings to uniformly discharge the second fluid in an axial flow direction into the mixing zone. The pipes extend beyond the pipe-plate into the mixing zone to partialize an outlet flow of the first fluid. In one aspect, the pipes have different lengths to partialize the outlet flow. In another aspect, a terminal portion of the pipes partializes the outlet flow axially, radially, transversally or a combination thereof in the mixing zone.

Abstract: A flame protection gasket has a gasket member with an embedded screen member within its structure. The screen member and gasket member are disposed in a common plane. The screen member is attachable to an air conduit structure in a manner that inhibits its removal after the attachment is completed. In addition, since the gasket member and screen member are part of an integral structure, the screen member must be replaced if the gasket member is replaced following repair or reassembly.

Abstract: In a fuel-air mixture device, downstream of a throttle (4) and a fuel introduction device, a block (51) is provided across the primary air passage (2). The block has a plurality of passageways (54) through it for air flow towards an inlet manifold. These improve mixture of the fuel and air.

Abstract: A reformer (5) which generates hydrogen-rich reformate gas by causing a catalytic reaction of fuel and air comprises a premixing chamber (12) for premixing the fuel with the air. High temperature air is supplied to the premixing chamber (12) from an air intake tube (13) via an orifice (14). A fuel injector (16) injects the fuel into the flow of the high temperature air in the premixing chamber (12) to generate fuel-air mixture. A homogenizing filter (17) homogenizes the composition of the fuel-air mixture in the premixing chamber (12) and supplies a uniform fuel-air mixture to a reforming catalyst (11).
