Abstract: A device for connecting lines associated with offshore drilling equipment comprises at least one support (24, 24') hinged to the platform by tie rods (25, 25') and movable between a position of withdrawal away from the drilling column and an operating position, near the drilling column, enabling the lines (19, 20) to be connected. A jack (35, 35') enables the support (24, 24') to be moved. In the operating position, the upper sections of the lines (19, 20) carried by the telescopic joint (2) of the drilling column have their joining members (17, 18, 21) located in concordance with the joining pieces (31) of the end parts (30) of the lines connected to the platform.

Abstract: Quick-action coupling for the elements of an extension tube used in ocean oil well drilling, comprising a female tubular element (3) and a male tubular element (4) of the rising column. When fitted into another, these form between them an annular groove (10) open in its upper part and limited in its lower part by an axial bearing surface made on the periphery of one of the tubular elements (3, 4), this having a dimension sufficient to allow the locking collar (13) to be introduced.

Abstract: Support structure for a solar collector consisting of two sets of bars linked by assembly nodes, a concave triangulated lattice (1) around the central node (10) positioned on the sighting axis (xx'), and a stiffening lattice (2) separated from the concave lattice (1) by struts (3, 6), the bars of the two lattices, positioned in a number of planes (P, Q, R) passing through the axis, constituting rigid half-trusses extending radially from a common central strut consisting of a column (3) positioned on the sighting axis (xx') and carrying at its ends the central nodes (10, 20) of the two sets of bars.
