Abstract: An improved riser 20 for a multiple bore subsea well provides wireline access to each of the bores through a single opening at the upper end of the riser. The riser includes an upper tubular member 30 having a single bore, a tubular housing 32 surrounding the lower portion of said upper tubular member, bearing means 34 within said tubular housing for supporting rotation of said upper tubular member with respect to said tubular housing, and a lower housing member 78 having multiple bores which mate with the multiple bores of the tubing hanger running tool or the christmas tree running tool. The upper tubular member has an offset portion within said tubular housing which, when rotated can align with the opening of the upper end of the bores through said lower housing member 78, and means to secure the lower end of said tubular housing to said lower housing member. A skirt 56 is connected to the upper tubular member within said tubular housing and extends into sealing engagement with the lower housing member 78 and is arranged in surrounding relation to said offset portion of said upper tubular member. The riser includes means for stopping the rotation of the upper tubular member in positions of alignment with the bores of said lower housing member, and means for providing an indication to the upper end of the upper tubular member of the position of the tubular member with respect to the lower housing bores.

Abstract: The invention relates to a vulcanising method for vehicle tyres, the tyre beads of which are arranged on the radially inner circumference of a rim when in the fitted position, the green-cover being vulcanised with the tyre beads folded out to the sides, using a heating press which has two axially displaceable contour rings, for casting the inner areas of the tyre beads, and a heating bellows, as well as an apparatus for carrying out the method. To make it easier to introduce the green-cover and to protect the heating bellows, it is proposed that, for charging the heating press, the contour rings are moved axially together and into a position above the vulcanising position in such a way that the evacuated heating bellows disappears downwards through a space bounded by the lower contour ring, that thereafter the green-cover is slipped over the contour rings, with slight oval deforming of the lower tyre bead, and is subsequently clamped by the contour rings moving axially further apart, the heating bellows at the same time passing into the interior of the cover, and that subsequently the cover is lowered and vulcanised.

Abstract: Superconductors comprising compositions represented by the respective formulae: TlBa₂Ca x Cu x+1 O y  wherein 0≦x≦10 and Tl₂Ba₂Ca x Cu x+1 O y  wherein 2≦x≦10. These Tl system superconductors are lower in Tl content than conventional Tl system superconductors and hence lower in toxicity attributed to Tl. Nevertheless, the critical superconducting temperatures of the superconductors are substantially the same as those of the conventional Tl system superconductors. Superconductors in the form of modifications of the above-mentioned superconductors wherein part of or all of Tl is substituted with In, Ga, Sb or Bi are lower in toxicity than the conventional Tl system superconductors and substantially the same in critical superconducting temperature as the conventional Tl system superconductors.
