Abstract: The present invention provides cryostat comprising a cryogen vessel 2 suspended within an outer vacuum container 4 by an arrangement comprising: at least one housing 20 mounted on an exterior surface of the outer vacuum container and arranged to function as a floor mounting foot, for supporting weight of the cryogen vessel and the outer vacuum container; at least two mounting points 26, 30 mounted within the housing(s); and at least two suspension elements 22, 23, being an upper suspension element 22 and a lower suspension element 23, each of the at least two suspension elements 22, 23 extending through a hole 32 in the surface of the outer vacuum container between the respective mounting point 26; 30 and a respective point on the cryogen vessel.

Abstract: A tensioning arrangement for a suspension system comprising an elongate suspension member (2) for attachment to an element to be suspended under tension at a predetermined location relative to a support surface (10); the arrangement comprising a lever arm member (1) having a component (5) adapted to engage with and support said elongate suspension member remotely from said suspended element, wherein said lever arm member is formed with first (7) and second (6) bearing means adapted to bear respectively against first (9) and second (8) spaced-apart regions of said support surface and wherein at least said first bearing means incorporates an adjuster means (3) permitting the said arm member to be moved relative to said first region of said support surface, thereby to permit adjustment of tension in said suspension member.

Abstract: A support system comprising a number of racetrack-shaped tensile support bands (22) held in tension between a supported article and a supporting article, respective curved end portions of each tensile support band being retained by respective mounting points (30) mounted on respective surfaces of the supported article and the supporting article, respectively. At least one of the tensile support bands is arranged so that the curved end portions lie in a plane substantially parallel to the surface upon which the respective mounting point is mounted; and at least one mounting point is a monolithic mounting point having a curved surface (32) which is complementary to an inner curved surface of an end of the tensile support band.

Abstract: A method of producing an adsorption medium to remove at least one constituent from a feed stream. The method comprises dissolving and/or suspending at least one metal compound in a solvent to form a metal solution, dissolving polyacrylonitrile into the metal solution to form a PAN-metal solution, and depositing the PAN-metal solution into a quenching bath to produce the adsorption medium. The at least one constituent, such as arsenic, selenium, or antimony, is removed from the feed stream by passing the feed stream through the adsorption medium. An adsorption medium having an increased metal loading and increased capacity for arresting the at least one constituent to be removed is also disclosed. The adsorption medium includes a polyacrylonitrile matrix and at least one metal hydroxide incorporated into the polyacrylonitrile matrix.

Abstract: A filter and method of forming a filter is described and which includes a porous inorganic substrate having a plurality of pores, and which permits the passage of a fluid therethrough, and a ceramic filtration media formed of particles having a particle size which permits the ceramic filtration media to be embedded in at least some of the porous inorganic substrate and positioned at and/or below the top surface of the inorganic substrate.
