A paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A method for monitoring a curing process of a cured-in-place pipe is disclosed. The method includes affixing a plurality of sensors to a resin layer of a liner, and determining a curing profile corresponding to at least the resin layer, the curing profile including a threshold curing value. The method further includes sensing, using the plurality of sensors, real-time data indicative of at least one curing parameter. Additionally, the method includes comparing the real-time data from each sensor to the threshold curing value, and outputting an alert upon the real-time data meeting or exceeding the threshold curing value.

Method for manufacturing a casing of an aircraft turbomachine, the casing including an annular shell extending about an axis A and made of a composite material including fibres that are woven and immersed in a resin, the annular layer including an abradable material arranged inside the shell, and covering a first inner annular surface of an intermediate section of the shell, the method including a step of gluing the layer on the first surface, during which the casing is heated and compressed by a system that is present at least partially inside the casing, wherein, prior to the heating and compression of the casing, a forming tool is mounted inside the casing and is made of two rings.

This heat-caulking device is inserted into one or more holes penetrating a main plate having a substantially conical hollow portion, whereby one or more bosses of a blade protruding from an inner peripheral surface of the main plate toward the hollow portion are melted so as to join the main plate and the blade. A heat chip of the heat-caulking device has a substantially conical hollow main body portion, an outer peripheral surface of which conforms to the inner peripheral surface of the main plate. On the outer peripheral surface of the main body portion, a convex portion protruding toward the vicinity of the holes of the inner peripheral surface of the main plate is provided.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

Methods, apparatus or equipment and systems for lining conduits, e.g., preferably subterranean pipelines and passageways, such as sewers, with a liner impregnated with a curable resin in order to secure the conduit against ingress or egress of liquids.

A steam generator for use with a liner assembly for pipeline repair or reinforcement, includes: a water heater configured to heat water to generate steam; a water feed conduit configured to convey water to the water heater; an air heater configured to generate heated air; an air supply conduit configured to convey pressurized air to the air heater; a heated air supply conduit configured to convey heated air from the air heater to the water heater to yield a steam-air mixture; and an output conduit configured to convey the steam-air mixture from the water heater. An automated steam generator system including the steam generator is also described.
