Abstract: A building module has an exterior shape generally of a cuboid having side, end, top and bottom faces, and fabricated from metal, the module being hollow and defining a space of a size suitable for occupation by a person. The module includes fastening elements (21, 69) to allow the module to be fastened to another adjacent module and to allow for engagement by standard load handling equipment for handling freight containers. The module has an overall exterior width greater than 2700 mm and includes a first set of fastening elements (21, 69A, 69B, 69C, 69D) in the region of a first end of the top of the module and a second end of the top of the module. The fastening elements of each set include two fastening elements (e.g. 21 and 69C) spaced apart from one another at a center-to-center spacing (D) of about (2260) mm.

Abstract: An integrated noise and heat management system for the management of noise and heat around a heat and noise source is described. The system includes an enclosure for surrounding the heat and noise source, the enclosure having a double wall structure defining an air space within the double wall structure. The double wall structure contains a heat exchange system in heat exchange contact with the air space and the heat source that enables the transfer of heat from the air space to the exterior of the enclosure and is doubly effective in attenuating noise from the noise source to the exterior of the enclosure.

Abstract: A method and system for network wide fault isolation in an optical network are described. A single fault in a network can produce a large number of alarms at different points in an optical network. The described method and system identify the root cause alarm while masking all correlated alarms. In the embodiment of the invention, the method and system are based on a wavelength tracker technology allowing identification and tracking of individual channels in the optical network.

Abstract: A solution for forming a fire resistant coating on substrates such as timber comprises an aqueous solution of an alkali metal silicate containing from about 5 to about 70% by weight of the alkali metal silicate and having dispersed therein a filer in an amount of from about 5 to about 60%. The filler is preferably an intumescent material such as a graphite capable of exfoliation. The solution may be applied by brushing or spraying onto timber in a mine to form coatings from 1 to 4 mm in thickness.

Abstract: The disclosure relates to a powder flow control valve comprising a nozzle formed from a material such as high density polythene having an upper frusto-conical section which converges towards the lower end of the nozzle and terminates in a cylindrical section. The nozzle is encircled by a plenum chamber to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system. When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle.
