The fixture arrangement is configured to enable the pipework to translate relative to the ball in an axial direction aligned with a longitudinal axis of the pipework.

Abstract: A duct stringer assembly with a bulkhead. The duct stringer assembly has duct walls providing a duct with a closed cross-section. The duct is adapted to transport fluid. A bulkhead is in the duct, and the bulkhead is adapted to block the flow of fluid along the duct. The bulkhead has a bulkhead body, and a gasket sealing a gap between the bulkhead body and the duct walls.

Abstract: A coupling for vacuum-insulated piping is disclosed having first and second parts for forming the coupling; each of the first and second parts comprising an inner portion for fluid communication with an inner part of a vacuum-insulated pipe and an outer portion for fluid communication with an outer, low pressure part of a vacuum-insulated pipe; the inner portions of the first and second parts form an inner region for the passage of fluid therethrough; each of the first and second parts comprising an interface portion for forming an interface with interface portion of the other of the first and second parts, the interface portion comprising a flange for connecting the first and second parts; each of the first and second parts comprises a sleeve surrounding the outer portion, the sleeve comprising a thermally-conducting portion that is in thermal communication with the interface portion so as to conduct heat away from the interface portion.

Abstract: An aircraft system has a first structure, and a second structure coupled to the first structure and movable between first and second positions relative to the first structure. The aircraft system has an electrical connector for providing an electrical connection running between respective components housed within the first and second structures. The electrical connector has a cable harness housed within the first structure, and a connector body coupled to an end of the cable harness. The connector body extends through an aperture formed in the first structure, and the connector body is coupled to the second structure such that movement of the second structure between the first and second positions relative to the first structure causes the connector body to move through the aperture.

Abstract: A breath-powered, dry powder inhaler, a cartridge, and a pulmonary drug delivery system are provided. The dry powder inhaler can be provided with or without a unit dose cartridge for using with the inhaler. The inhaler and/or cartridge can be provided with a drug delivery formulation comprising, for example, a diketopiperazine and an active ingredient, including, peptides and proteins such as insulin, oxyntomodulin and glucagon-like peptide.

Abstract: A double-wall pipe for an aircraft fuel system includes an inner wall defining a first open end, a second open end, and an inner region connecting the first open end to the second open end and via which a fuel is flowable through the double-wall pipe, in use. The double-wall pipe includes an outer wall at least in part around the inner wall to define an interspace, between the inner wall and the outer wall, that is fluidically isolated from the inner region. The double-wall pipe includes at least one barrier that is openable to create a passage that fluidically connects the interspace to the inner region. The at least one barrier is configured to open when a pressure in the interspace is higher than a pressure in the inner region.

Abstract: A pipe joint including an outer pipe assembly having a first outer pipe portion, a second outer pipe portion, and a shroud coupling the first and second outer pipe portions. The outer pipe joint includes an outer securing mechanism securing the shroud to the second outer pipe portion. The inner pipe assembly, within the outer pipe assembly, includes a first inner pipe portion coupled to a second inner pipe portion via an inner pipe joint. The inner pipe assembly provides an inner fluid flow path extending axially and across the inner pipe joint. The shroud is movably mounted to the first outer pipe portion, and the outer securing mechanism is releasable so the shroud can move along the first outer pipe portion and withdrawn from the second outer pipe portion to open a gap between the shroud and the second outer pipe portion for the inner pipe joint.

Abstract: A coupling for connecting vacuum-insulated piping is disclosed. The coupling facilitates the detection of unwanted fluid ingress into the low pressure insulating outer portion of the vacuum-insulated piping and the detection of a leak from the central portion of the vacuum-insulated piping that is used to carry cold fluids. This is achieved by providing a first leak path from the central portion of the vacuum-insulated piping to a sensor outlet and a second leak path from the outer portion of the vacuum-insulated piping to the sensor outlet. One sensor may be used to detect unwanted fluid ingress into the low pressure insulating outer portion and also detect a leak from the central portion of the vacuum-insulated piping.
