Abstract

1341718 Cryogenic connections COMPAGNIE GENERAL D'ELECTRICITE and L'AIR LIQUIDE LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 3 Sept 1971 [8 Sept 1970] 41297/71 Headings H1A and A4D A cryogenic connection, Fig. 2, comprises conductors 3; an inner fluid tight enclosure 1; a fluid tight heat shield 4 comprising cooling channels 22 in each face, a base portion 29 and a cover portion 19; and an outer fluid tight enclosure 5, pipes 17, 18 being provided to evacuate the space between the heat shield and the outer and inner enclosures respectively. Insulation material 6, e.g. an aluminabased powder is provided and cables 7, 9 support the inner enclosure and heat shield respectively. Polytetrafluoroethylene beads 8, 10 on the cables allow the triangular ducts to expand or contract longitudinally. Projections 20, 21 and ribs, e.g. 26, 27 are provided for strengthening purposes. Spot welding along the flattened margin portions 12, 14 of the enclosures secures the margins of each strip together and a continuous weld 28, 16 along and across the edges of each strip renders each enclosure fluid tight. The cooling liquid flowing through the connection may be as follows: liquid helium along the ducts 30; liquid nitrogen along ducts 22 and liquid helium along the ducts 2, said duct bounded by the surfaces of the conductors and the inner enclosure. The cable is manufactured in situ by forming machines which travel over the metal strips from which the components are made, laid out at the laying location. Firstly the outer enclosure is formed from a flat sheet steel strip into the configuration of Fig. 2 and the base portion of the heat shield is formed from an aluminium strip and suspended within the outer enslosure. The cooling channel in the base of the shield is formed by a "roll-bond" method, ink being applied between the metal layers to prevent welding in that area and then using air-pressure to expand the channel Figs. 11a, 11b, 11c, (not shown). Then the inner enclosure is formed out of a stainless steel strip, the conductors located therein and the enclosure closed and sealed. The top portion of the heat shield is then formed out of aluminium and the inner enclosure with the conductors is suspended therein. The heat shield top is assembled on its base, the insulation added. The vacuum connection pipe is inserted and the outer enclosure is then closed and sealed, Fig. 9.
