摘要： Systems and methods are described for applying a self-heating structural adhesive to components of aircraft or other structures. A conductive scrim can be placed in between layers of adhesive for use in joining two components together. Leads can be provided to apply an electrical current to the scrim, which can raise the temperature of the system and cure the adhesives, creating a strong bond with a conductive layer there between.

摘要： A heat-seal band is provided that incorporates voltage sensing wires, such as signal wires or conductors that are separate from current load carrying wires or conductors. This provides two discrete electrical paths: a voltage sensing path, and a current transmission path. The voltage signal conductor(s) in the voltage sensing path may be insulated to mitigate any non-desired influence by means of the voltage signal conductor's exposure to thermal or electrical influences from the current transmission path, including current transmission paths defined through conductive tabs that connect the heat-seal band to the current load conductors. The voltage signal conductor may connect at a node to the tab to band (tab/band) junction, which is defined at an intersection of the heat-seal band's conductive tab and the band that directs heat into a workpiece. Additional or a second set of voltage sensing conductors may be electrically connected to the heat-seal band at a location that is spaced from or in a subset of the first set of voltage sensing conductors. The second set of voltage sensing conductors may provide a secondary voltage sensing arrangement as a verification tool for evaluating temperature discrepancies between their locations and those of the first set, indicative of heating non-uniformity about the heat-seal band.

摘要： A rigid conduit (for example, a metal conduit) featuring an electrofusable section secured to the rigid conduit to allow the rigid conduit to be electrofusion welded to another component of the fueling installation, such as a sump or further electrofusable conduit, is provided by the present disclosure. In certain exemplifications, multiple spaced electrofusable sections are provided on the rigid conduit, with corrosion resistant sections spanning the electrofusable sections in certain arrangements.

摘要： A method for resistance welding of two fiber-composite components to give a fiber-composite structure includes arranging conductive fibers within a jointing region of the two fiber-composite components, where each conductive fiber includes a carbon fiber with an electrically insulating coating. An electric current is passed through the conductive fibers to heat the jointing region to a welding temperature and melt the fiber-composite components in the jointing region. The jointing region is hardened in a manner that bonds the two fiber-composite components by way of the jointing region to give the fiber-composite structure.

摘要： A heat shrink component includes a heat shrink layer and a heating unit in thermal contact with at least a part of the heat shrink layer and heating the heat shrink layer to a heat shrink temperature. The heating unit includes an electrically conductive lead formed of copper and/or aluminum and having an electrical conductivity of more than 3·107 S/m. The heat shrink component has a first dimension in an expanded state and a second dimension in a shrunk state after heating. The first dimension is larger than the second dimension.

摘要： Assemblies, apparatus, and methods for heat sealing and monitoring are disclosed. A dual heat-sealing system includes a heat seal bar assembly with process monitor that allows to quickly change out heat bands and ensure that the effective length of the heat band matches the width of the seal (of the material being sealed), providing consistent and superior seal quality. A heat seal bar assembly includes multiple heat bars sized to easily match the size of the pouch being sealed. The heat bars are removable and replaceable. The heat bars are provided with at least one memory chip. The memory chip allows for storage and retrieval of information regarding the replaceable heat bar.

摘要： A liner bridge for a lined pipeline has bores extending through a tubular wall and terminals fitted in the bores, each terminal being exposed to an inward side of the wall for conducting electricity to an electrofusion element. A sealing interface between each terminal and its surrounding bore has one or more projecting formations of the terminal and at least one complementary formation of the bore engaged with the or each of the projecting formations. The interface can also include a sealing mass in the bore.

摘要： A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; and a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe. The first pipe and the second pipe are made from a reinforced thermosetting resin (RTR). The coupler comprising a resistive element implanted therein and connected to electrodes extending to an exterior of the coupler. A thermoplastic material is disposed between an exterior of the first pipe and an interior of the coupler. A thermoplastic material is disposed between an exterior of the second pipe and the interior of the coupler. Upon application of electricity to the electrodes, the resistive elements are heated sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler. A method of coupling pipes includes disposing a thermoplastic material between an exterior of a first pipe and an interior of a coupler; disposing a thermoplastic material between an exterior of a second pipe and the interior of the coupler; inserting the first pipe and the second pipe into the coupler; and applying of electricity to electrodes of the coupler such that resistive elements of the coupler heat sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler.
