The liner conducts heat away from the evacuated chamber to a surrounding cooling fluid.

The casing includes a sealable passageway (14) defined between the atmosphere and the interior of the casing, and is configured to permit injection of fluid, and removal of vapors and extant fluid with a vacuum from the casing.

A ventilation duct is provided in the hoistway.

The refrigeration jacket includes a plurality of channel members.

A shell defines an enclosed channel to form the shaft.

A pipe liner installation apparatus (10) for installing a flexible liner (60) into an internal connecting region between a main pipe (12) and a target branch pipe (13) is disclosed.

The interior of the inner casing is connected to either the inlet or the outlet (4, 5) while the space between the filter housing (1) and the inner casing (3) is connected to the other of said inlet or outlet.

A rapid exchange assembly (10) comprises an introducer sheath (12) , and a dilator (16) receivable within a lumen of the introducer sheath.

The present invention relates to a protective sheath (12), a conduit assembly (11) including a protective sheath (12), and a method of forming a protective sheath (12).

The fluid conduit is interposed between the inner tube and the outer sleeve.

An underwater cladding for an elongate member such as a pipe (10) has outwardly projecting flexible members (16, 24, 28) which are deformed by a current flow to guide water around the elongate member.

The operation wire (20) is inserted into a conduit (10a) of the sheath (10).

Portions of the jacket intermediate the ducts connect to the strength member which resists longitudinal movement of the jacket relative to the core.

Convoluted conduit (1) covered with braid made by cold forming the braid to an end conduit (3) or an end section of the convoluted conduit.

The modular terminals can selectively draw air from a plenum, duct, or both.
