Abstract: A device for sealingly linking two end pieces (24) of a fluid line system, comprises a casing part (1) and an inner part (13). The inner part (13) is arranged in a prefabricated arrangement within the casing part (1) in an axially displaceable manner and serves to fixate a sealing unit (21) that is detachably linked with the inner part (13) until an end piece (25) is inserted into the casing part (1) via an introduction area (3) and comes into contact with the inner part (13). When the end piece (25) is inserted, the inner part (13) is axially expelled from the casing part (1), whereby the sealing unit (21) is inhibited in its axial movement by an abutment (12) and remains within the casing part (1). The two end pieces can be sealingly linked while indicating the relative position of the end piece (25) coming into contact with the inner part (13) without requiring a separate handling of the sealing unit (21).

The inner wall encompasses a through passage which is open to the space encompassed within the lower section. A line of a given diameter can thus be received and maintained around the side walls. Another line of different diameter can be received and maintained within the channel and lines of other different diameters can be maintained within the through passage.

Abstract: The invention pertains to the sensing and measurement of infrasound (pressure variations with frequency content under 10 Hertz). The invention measures the infrasound pressure variations and then attenuates undesired contributions due to, but not limited to, changes in ambient fluid speed and changes in altitude of the sensing device. The undesired contributions are attenuated using an adaptive filter with the measurements of the change in ambient fluid speed and the change in altitude. This approach differs from existing applications of adaptive filtering in that the invention uses measurements of speed and displacement to improve a pressure measurement. This approach differs from existing methods for attenuating the affects of the wind on the measurement of infrasound in that it does not require the use of a large spatial averaging filter.

The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives.
