Abstract: Mobile training labs for training gas technicians are disclosed. The mobile training labs can include a towable trailer comprising a body having a plurality of walls at least partially defining a hollow interior, an axle having at least two wheels disposed thereon to support the body, and a tow hitch. The mobile training labs can also include at least one training bay connected to the towable trailer such that the at least one training bay is configured to be accessed from an exterior of the towable trailer. The at least one training bay can include a work bench and a mock service entrance that is representative of a commercial or residential gas service entrance.

Abstract: An assembly that includes a rotating component and flexible coupling. The flexible coupling includes a flexible torque disc having a first plurality of fixing points so that it can be mounted upon a first rotatable component, in use, and a second plurality of fixing points so that it can be mounted upon a second rotatable component, in use. The coupling also includes a support ring, and mounting means so that the flexible torque disc is secured to the support ring. The mounting means restrict deflection of the flexible torque disc relative to the support ring.

Abstract: A flexible coupling comprises a flexible torque disc (24) having a first plurality of fixing points (24a) whereby it can be mounted upon a first rotatable component (12), in use, and a second plurality of fixing points (24b) whereby it can be mounted upon a second rotatable component (14), in use, a support ring (26), and mounting means (34) whereby the flexible torque disc (24) is secured to the support ring (26), the mounting means (34) restricting deflection of the flexible torque disc (24) relative to the support ring (26).

Abstract: A pressure vessel includes front and rear end plates and a plurality of open-ended vessel structures constructed of fibre-reinforced polymer matrix composite material positioned adjacent to one another so that their longitudinal axes are parallel to a longitudinal direction extending between the front and rear end plates. The vessel also includes an outer reinforcement comprising polymer matrix composite material with continuous fibres extending longitudinally around the pressure vessel to secure the front and rear end plates to the vessel structures. At least one of the vessel structures has a partially curved cross section in a plane perpendicular to its longitudinal axis, such that one or more crevices are formed between the vessel structures, running longitudinally between the front and rear end plates and the front and rear end plates are shaped to allow the outer reinforcement to at least partially fill the one or more crevices between the vessel structures.

Abstract: A connector assembly includes a connector for connecting a hollow composite shaft that has been manufactured to comprise an inwardly tapered portion towards one end of the hollow composite shaft to a collar includes an insert, a collar and a tensioner. The insert is received in the tapered portion of the hollow composite shaft such that the inner surface of the tapered portion of the hollow composite shaft in use will engage with the outer tapered surface of the insert and collar includes an inner tapered surface and being sized to fit over the insert and the tapered portion of the hollow composite shaft. The tensioner is arranged, in use, to axially force the collar and the insert in opposite directions so as to exert a clamping force onto the tapered portion of the hollow composite shaft. A method of forming the assembly is also included.

Abstract: A composite tubular structure is described suitable for transmitting axial loads in compression or tension. It comprises an elongate composite member 70 having a nut 50 retained in each end for forming a connection with another component. The composite member further comprises an inwardly tapered section at each end, each of which has an inner surface that follows a tapered outer surface of one of the embedded nuts. The inwardly tapered section narrows the composite member in a longitudinal direction towards one end so as to provide a constriction which retains the respective nut within. A connector 80, 84, 86 may clamp the end with a pre-load. A liner 60 may be used to support the nuts during deposition of the filaments in order to form the two inwardly tapered sections at the ends. It can allow the wall of the structure to be formed with different profiles.

Abstract: A method of connecting a hollow composite shaft to a collar is provided. The method comprises providing a hollow composite shaft with a tapered portion towards one end, inserting an insert into the tapered portion of the hollow composite shaft by passing the insert through the hollow composite shaft from the end of the hollow shaft which is distal to the tapered portion of the hollow composite shaft, fitting a collar over the insert and tapered portion of the hollow composite shaft, and axially forcing the collar and the insert in opposite directions.

Abstract: One or more online configuration settings are received prior to deployment and execution of a software appliance. Once the configuration settings have been received, the online configuration settings can be utilized to configure a software appliance image prior to executing the image at a host computer. Once the application of the configuration settings to the image has been completed, the image may executed at a host computer.
