A conduit for transferring fluid from one location to another. The conduit includes a tube having an outer surface and an insulation layer surrounding the tube. A heating layer is disposed between the insulation layer and the tube, such that the heating layer is wrapped around the outer surface of the tube. The conduit includes a reinforcement layer sandwiched between the insulation layer and the heating layer.

A line connector for media lines including a fluid connector having at least one connection section for terminal connection to a fluid line and having a transition section with an inner fluid channel adjoining the connection section. An electric heating element is provided at least in certain areas. The fluid connector is encased by encapsulation at least in the region of the heating element. The encapsulation has a branch for an electric supply conductor for the heating element. A ready-made media line includes the above mentioned line connector and an attached fluid line.

A bulk adhesive transfer system for transferring adhesive particulate to a melter includes a bulk supply and a transfer device, which may define a hopper of the melter, a mobile bin, and/or a buffer unit. The transfer device is configured to receive unmelted adhesive particulate from the bulk supply and then be selectively docked with the melter to transfer the adhesive particulate to the melter. The bulk adhesive transfer system may also include a knife gate valve device, which includes a plurality of ports that sequentially open and close to control flow of the adhesive particulate towards the melter. The bulk adhesive transfer system simplifies refilling operations for a melter while enabling continuous operation of the melter, even when the transfer device is undocked for removal from the melter.

A rigid pipe-in-pipe structure for subsea transportation of fluids includes inner and outer pipes defining a thermally-isolating annulus between them. Thermal insulation material is disposed in the annulus. The outer pipe is of metal, preferably carbon steel. The inner pipe is a polymeric composite structure of bonded layers including a first, radially outer tubular polymeric electrically insulating layer, which can be of p polymer, surrounding a second, composite layer including carbon fibres, preferably continuous fibres, embedded in a polymer matrix. Conveniently the second layer is a heating layer in which the carbon fibres conduct electricity to heat the inner pipe. The inner pipe can also comprise a radially inner tubular polymer layer within the second composite layer.

A method of sealing an annulus of an electrically trace-heated pipe-in-pipe structure including introducing a flowable filler material to mould a sealing mass in situ is disclosed. The sealing mass closes a restriction at which the annulus is narrowed radially and embeds at least one heating element that extends generally longitudinally through the restriction. The structure includes an inner ring spaced within an outer ring to define the annulus between the rings. The annulus is narrowed radially by one or more projections that extend radially into the annulus from at least one of the rings toward the other of said rings. The restriction may include multiple bores, each of which may contain a sealing mass around a respective heating element in the bore.

Condensation or rain-out is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube preferably incorporating a heater wire.

An exhaust outlet elbow includes: a body having an outer wall and an interior wall, the interior wall defining, at least in part, an interior chamber; a connecting surface located above the interior chamber; and an array of threaded holes located about the connecting surface, wherein the threaded holes terminate in the body. A method of manufacturing an exhaust outlet elbow includes the steps of: forming a body having an outer wall and an interior wall, the interior wall defining, at least in part an interior chamber; forming an connecting surface located between the interior and outer walls; and forming an array of threaded holes in the connecting surface.

An anti-ice buildup system for roof vent pipes that is easy to install and that prevents ice buildup in roof vent pipes. The anti-ice buildup system for roof vent pipes generally includes a first segment and a second segment extending downwardly from the first segment. At least a portion of the first segment is adapted to remain outside of a vent pipe and at least a portion of the second segment is adapted to extend downwardly through an upper opening in the vent pipe. The second segment is constructed of a thermal conductive material to conduct heat from the vent air and sunlight.

A subsea direct electrical heating assembly adapted to heat a hydrocarbon conducting steel pipeline (1) arranged subsea. The assembly comprises a direct electrical heating cable (3) extending along and being connected to the steel pipeline (1) and a power transmission cable (7) receiving electric power from a power supply (5) which is arranged onshore or at surface offshore, and which feeds the direct electrical heating cable (3). The subsea direct electrical heating assembly comprises a power conditioning arrangement (100) arranged at a subsea location, in a position between the power transmission cable (7) and the direct electrical heating cable (3). The power transmission cable (7) extends from the offshore or onshore power supply (5) and down to the power conditioning arrangement (100).

A multi-layered hot melt adhesive transfer hose is provided. The transfer hose has a barrier layer that prevents or minimizes the ingress of oxygen and other gases into a conduit of the hose. The transfer hose has at least one structural layer overlaying an exterior surface of the barrier layer to help the hose withstand a high fluid pressure. The barrier layer prevents the hot melt adhesive being transported in the hose from discoloring and charring when the adhesive is heated from about 250 F. up to and including 450 F. for an extended period of time.
