Abstract:
A structure (2) is constructed using at least two types of bracket (12, 10, 14) in which each bracket (12, 10, 14) is adapted to engage with an end region of at least one elongate structural member (6 or 8) via a length of channel (22) with substantially parallel side walls and a base plate extending there between. The structure includes at least one elongate structural member (6 or 8). The structure (2) is a frame suitable to support a roof or cover.
Abstract:
A temporary structure is provided. The structure comprises a frame (10) and at least one top beam (22) characterised in that the or each top beam (22) is releasably attached to the frame (10) via at least one bracket (18, 20) per top beam (22), each top beam (22) being so affixed that it has at least one free end (24), said free end (24) being so positioned that it is not vertically above the frame (10). The temporary structure is constructed adjacent the face (4) of a building (2) and is used to support a membrane (26) which forms a volume adjacent the frame (4) separated from the general environment.
Abstract:
The invention provides apparatus suitable for moving a roof truss (8) along a pair of wall plates (14,16) comprising a pair of trolleys (20) in which each trolley (20) is comprised of a . body (22) and at least one roller means (24) in which each roller means (24) is attached to the body (22) and adapted to roll along a wall plate (14,16) and a portion of the body (22) is adapted to support an end (10,12) of a roof truss (8) when each roller means (22) is in contact with the wall plate (14,16).
Abstract:
A system and method for network fault diagnosis in a network having network elements is presented The method comprises creating a network causality model, generating Boolean expressions from the network causality model, converting the Boolean expressions into SAT sets, receiving network monitoring results, correlating these monitoring results with the SAT sets, and enumerating all possible diagnostic explanations of potential faults, properly annotated. Creating a network causality model can comprise creating, for each network element, an element-specific causality model, stitching together all network elements using the element-specific causality models and a network topology, retrieving monitoring state and propagation information, and generating the network causality model using the stitched together network elements and the monitoring state and propagation information. Stitching together network elements can comprise adding causes and implies dependency between appropriate network elements and/or adding and connecting reachable and not-reachable states.
Abstract:
A composite suspension element including a spider and/or surround for high-power, compact electro-acoustic transducers comprises a non-woven fiber blend encased in a thermoplastic elastomer. The composite suspension element is capable of supporting the longer stroke distances of the high-power, compact electro-acoustic transducers and exhibits improved fatigue and ageing resistance.
