A low-pressure tubular system, for instance a vacuum tube train transportation system, comprising: a multitude of interconnected tube sections having a longitudinal axis; wherein each of the tube sections comprise a central part and two outer end parts; wherein the tubular system is configured to maintain a low-pressure environment within the connected tube sections; wherein the system further comprises a multitude of expansion joints connecting the tube sections; wherein each of the expansion joints comprises a sleeve made of a flexible sheet material and comprising a ring shaped endless central part and two ring shaped endless outer end parts; and wherein each of the outer end parts of the expansion joints are arranged to extend coaxial with an adjacent tube section and surround and sealingly engage the outer end part of said adjacent tube section.

The flexible duct connector processing system of the present invention comprises a decoiler machine and a processing machine. The decoiler machine stores one or more rolls of flexible duct connector stock which are fed to the processing machine. The processing machine beads, notches, and cuts the flexible duct connector stock according to programmed instructions received from a control system. A conveyor system disposed after the processing machine optionally collects the cut flexible duct connector stock and conveys it in batches.

A gasket for sealing a gap between a through hole formed on a wall body and a pipe to be inserted into the through hole, the gasket being provided for the pipe and made of tubular elastic material, the gasket having an inner circumferential lip portion which elastically contacts an outer circumferential face of the pipe; and an outer circumferential lip portion which elastically contacts an inner circumferential face of the through hole; an inner seal area on an inner circumferential side where the inner circumferential lip portion is provided is located at a position so that the inner seal area does not overlap in a radial direction with an outer seal area of an outer circumferential side where the outer circumferential lip portion is provided.

A fluidic connector to connect two ducts of a system such as an air conditioning system. The connector includes at least one elastic material, and includes a duct surrounded by an adjustable clamping collar which, when tightened, serves to deform it to reduce the internal space of the duct. The clamping of the collar makes it possible to easily and quickly regulate the rate of flow in the ducts.
