A lateral applicator kit for a pipe has a first and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral walls of a pipe. The first unit receives primer through a first supply engagement feature, which is in fluid communication with a first material reservoir internal to the first application unit and further in fluid communication with an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The application receptacle has at least one first material applicator connected across at least one first application opening through which primer is absorbed and distributed to the pipe. The application receptacle has a tapered, flexible applicator wall for adaptably accommodating a range of pipe diameters. The second unit is similarly but inversely configured to adaptably apply primer to the interior surface of a fitting.

A method of impregnating a fiber texture of hollow shape, the method including introducing a first suspension containing a first powder of solid particles of ceramic or carbon material into an inside volume defined by an inside face of a fiber texture of hollow shape placed in a mold, an outer face of the fiber texture being presented facing a wall of the mold; and using the action of centrifugal force to impregnate the fiber texture with the first suspension by causing the mold to rotate and varying the speed of rotation of the mold during the impregnation of the texture with the first suspension.

A lateral applicator kit for a pipe has a first application unit and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral surfaces of a pipe, respectively. The first application unit is configured to receive primer through a supply engagement feature, which is in fluid communication with a reservoir cavity internal to the first application unit and further in fluid communication with at least one perforated annular wall of an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The second application unit is similarly but inversely configured to apply primer to the interior lateral surface of a pipe by receiving primer into a supply receptacle, which is transferred through at least one spout set into and through an annular distributing container connected annularly around the supply receptacle.

The present invention is an implantable medical device comprising (i) a base coat layer having an inner and outer surface, the inner surface of the base coat layer contacting the implantable medical device; (ii) a top-coat layer of a hydrophilic polymer chemically crosslinked and covalently bonded to the outer surface of the base coat layer, the hydrophilic polymer comprising an anionic polyelectrolyte; and (iii) an amount of a hydrophilic cationic drug agent added to the top-coat layer sufficient to provide an effective dosage of the drug agent for delivery to a patient, whereby the hydrophilic cationic drug agent is initially adsorbed into the anionic polyelectrolyte of the top-coat layer and the hydrophilic cationic drug agent having a release rate after the medical device is implanted within a patient's body.

A reactor for coating a device is provided. The reactor comprises a hollow body and a port. The hollow body is for supporting the device. The port is in fluid communication with the hollow body for exchanging a coating fluid. In use, the device is moveable within the hollow body from a stacked orientation to an unstacked orientation. Processes for coating devices and systems thereof are also provided.

An air purging coater apparatus is disclosed for purging mixed components from the apparatus disposed in a pipeline at a pipeline site. The apparatus includes a remote-controlled apparatus for insertion within the pipeline at the pipeline site. The remote-controlled apparatus includes a drive for controllably moving the remote-controlled apparatus internally within the pipeline. A high-pressure mixing device defines a first inlet controllably connected to a pressurized source of a first component. The high-pressure mixing device also defines a second inlet controllably connected to a further pressurized source of a second component. The high-pressure mixing device defines a high-pressure mixing chamber connected to the first and the second inlets for mixing together the first and second components. The high-pressure mixing device defines an outlet connected to the high-pressure mixing chamber for receiving a flow therethrough of the mixed components. A spin head defines an internal conical surface having an apex which cooperates with the outlet of the high-pressure mixing device for receiving the flow of the mixed components. The spin head includes a baffle which is disposed adjacent to the apex such that when the spin head is rotated, the mixed components are deflected by the baffle onto the internal conical surface so that the mixed components are applied to an inside surface of the pipeline at the pipeline site. The high-pressure mixing device is controllably movable from an application disposition thereof to a purging disposition, the application disposition being such that the first inlet and the second inlet are aligned with and in fluid communication with the respective pressurized source and further pressurized source so that the mixed components are applied to the inside surface of the pipeline. When the high-pressure mixing device is controllably moved to the purging disposition, the first and second inlets are moved out of alignment with the pressurized sources so that the flow of the mixed components is terminated and a source of pressurized air flows into and through the first and second inlets and from the inlets through the high-pressure mixing chamber and the outlet for purging any residual mixed components from the high-pressure mixing device thereby avoiding any need for the use of a potentially hazardous solvent together with life threatening conditions that could result from the introduction of such solvent into the pipeline at the pipeline site.

A bar element as a construction element includes strips preferably produced from bamboo and is hollow at least in certain regions. The hollow interior is formed at least in certain sections as a hollow fillet achieved by a plastic and/or resin introduced into the bar elements, using a shaped body movable through the interior. Producing bar elements from interconnected strips ensures that although produced from a natural raw material, the bar elements have a reproducible outer cross section. Using a shaped body movable through the interior to produce the inner cross section also ensures a defined inner cross section of the bar elements, with the result that in turn connections between a plurality of bar elements that are defined by suitable connection elements can be formed. In this way, the bar elements make it possible to produce lattice works, grid constructions, frameworks or other desired structures and/or three-dimensional bodies.

A method of automated pipeline chemical batch treatment includes receiving treatment information at a control system of a pipeline. If the treatment information includes an instruction to activate a pump system, the method includes transmitting an activation signal from the control system to the pump system in accordance with the treatment information. The activation signal causes the pump system to pump one or more chemicals from a chemical feed system into the pipeline. If the treatment information includes an instruction to deactivate the pump system, the method includes transmitting a deactivation signal from the control system to the pump system in accordance with the treatment information, wherein the deactivation signal causes the pump system to stop pumping one or more chemicals from the chemical feed system into the pipeline.
