Abstract: An apparatus for facilitating delivery of conditioned air across a barrier in a cage for holding an animal patient to a blanket arrangement providing the conditioned air to the patient. The apparatus comprising a first duct part, a second duct part and a mounting mechanism arranged to mount the first duct part on one side of the barrier and the second duct part on the other side of the barrier opposite thereto, to provide a duct for ducting conditioned air across the barrier. The barrier comprising bars or mesh, and the apparatus further comprising a seal arrangement to provide at least a partial seal across the bars or mesh. The mounting mechanism comprises a fastening mechanism for fastening the first and second duct parts to each other across the barrier, wherein the fastening mechanism is a keyhole-style fastening arrangement utilising a plurality of headed projections on a flange of the first duct part engagable with respective keyhole-style apertures on a flange of the second duct part.

Abstract: A connector for providing a leak resistant flow path between fluid conduits includes a female connector, a male connector, and a tubular fluid conduit that extends through a conduit passage in the male connector and into a conduit receiving passage in the female connector. The connector can include optional anti-cantilever features that provide a more effective axial seal when using a seal washer recessed into a planar surface of the male connector to supplement a radial seal provided by an O-ring sealing member between the tubular fluid conduit and the conduit receiving passage.

Abstract: An assembly 10 includes a coupling member 12 having a first annular, radial connection flange 22 and a blanking cap 14 comprising a disc-like member 30 which defines a second, corresponding annular, radial connection flange 34. The connecting flanges are clamped together by a clamp (16) with a seal member 18 in-between. The blanking cap comprises a pair of safety lugs 62 attached to the disc-like member which each extend about an outer circumferential periphery of the first connection flange 22. Each safety lug has an abutment 68 for engagement with the first connection flange to limit axial movement of the disc-like member away from the coupling member. The lugs 62 prevent the blanking cap from flying off in the event the clamp is released whilst the interior of the coupling member is pressurised. The lugs 62 may each have a stop member 66 which defines the abutment and which may take the form of an elongate curved member extending circumferentially about an axis of the connection flanges. The clamp may be tri-clamp.

Abstract: Improved expanded PTFE materials and improved gasket materials made therefrom, the gaskets being capable of forming a seal with greater bolt load retention than is possible with existing, PTFE gaskets. The expanded PTFE membranes of the invention can be tailored to exhibit a matrix tensile strength in at least one direction of at least 25,000 psi, a matrix tensile strength ratio in two orthogonal directions of between .025 and 4, an orientation index of 50 or less, and a density of 2.0 g/cc or less. The improved gaskets exhibit improved mechanical properties such as high bolt load retention, low creep, high tensile strength, low stress to seal and high crystallinity index.
