A gasket comprising a first discrete component and a second discrete component, wherein the first and second components extend along the length of the gasket. The second component is arranged ranged relative to the first component so as to separate the first component at least from one of the two sealing surfaces. The first component is relatively hard in at least the thickness direction of the gasket and preferably incompressible and the second component is relatively soft in at least the thickness direction of the gasket and compressible. When the gasket is compressed between two flanges, there is a limited region of high compression, because the first component increases the pressure by which the second component is compressed between the surfaces of the flanges. This yields a high leak tightness of the sealing at a relatively low force.

An invention describes a drapable IR-reflecting material for garments. The IR-reflecting material comprises a water-vapor-permeable metallized ply supporting an air-permeable drapable convective ply having a three-dimensionally transmissive structure. The outer surface of the convective ply, said outer surface being opposite to the metallized ply, is formed by an air-permeable sheetlike structure. The convective ply causes heat convection of temperatures reflected by the metallized ply in order that the outer surface of the convective ply may be brought into line with the ambient temperature.

Improved acoustic attenuation materials and applications are provided. An improved acoustic attenuation material may include a woven layer of fibers made of porous polymers, such as porous polytetrafluoroethylene (PTFE), that include interstitial space. An improved acoustic attenuation material may include sheets of porous polymers interleaved with layers of epoxy. The sheets of porous polymers may include through holes. An embodiment of an ultrasonic transducer that includes a backing with woven layers of porous PTFE fibers is provided. The ultrasonic transducer that includes a backing with woven layers of porous PTFE fibers may be used in a three-dimensional ultrasound imaging apparatus. An embodiment of an ultrasonic transducer that includes a plurality of sheets of porous PTFE interleaved with layers of epoxy is provided. The ultrasonic transducer that includes a plurality of sheets of porous PTFE may be used in an ultrasonic imaging catheter.
