Abstract: A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an axial strengthening means (20) adapted to reduce deformation of the tubular body (12) when the tubular body (12) is subjected to axial tension, the axial strengthening means (20) being adapted to exert a radially inward force on at least part of the tubular body (12) when axial strengthening means (20) is subjected to axial tension.

Abstract: A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an elongate member having opposing longitudinal edges, the elongate member being helically wound around the tubular body such that the opposing longitudinal edges of the layer are in an adjacent or overlapping arrangement, wherein each longitudinal edge includes a formation capable of interengaging with a cooperating formation on the opposing longitudinal edge.

Abstract: An end fitting for terminating an end of a hose including a tubular body of flexible material arranged between inner and outer gripping members, wherein the end fitting includes: an inner member adapted to be disposed at least partially within the hose; a sealing member adapted to seal at least part of the tubular body fully around the circumference between the sealing member and the inner member; and a separate load transfer member adapted to transfer axial loads between the hose and the inner member in such a manner that said axial loads are diverted around the sealing member in order to reduce, or eliminate, the axial load on the hose between the sealing member and the inner member, and wherein the sealing member is adapted to seal against the tubular body independently of the application of axial loads between the hose and the inner member.

Abstract: An apparatus and method for mounting free-space optical communications system (FSO) equipment to a window. The apparatus includes a substantially rectangular frame member in which a central opening is defined. In one embodiment, the frame member comprises an extrusion that may be cut to a desired length to fit various window widths. The frame member is coupled to a window frame or the window via a plurality of universal mounting brackets. A support that is operatively coupled to the frame member provides a mounting interface to couple to an FSO terminal that is disposed within the central opening. In one embodiment, the support comprises a gimbaled support that enables the FSO terminal to be rotated about a pair of orthogonal spin axes. A valance is provided to prevent undesired access to the gimbaled support and FSO terminal and make the apparatus appear less obtrusive.

Abstract: A compact, lightweight free-space optical communication system is mounted to a window, such as to a surface of the window. Mounting can be accomplished using glue, vacuum devices, or other fastener devices or fixtures. The optical communication system has features that compensate for window dynamics and other window characteristics, including fast steering solutions for pointing and tracking, and terminal size and weight factors.

Abstract: Metal ions may be scavenged from solution by means of a complexing agent comprising an inorganic substrate, such as a clay mineral, with covalent organic molecules, such as onium compounds, chemically bonded to the substrate, the covalent organic molecules containing free coordinating groups. The complexing agents are particularly useful in scavenging environmentally harmful metal ions such as mercury from industrial effluents.
