A double tripod arrangement in which the legs of a first tripod extend to a fixed angle and the feet of a second tripod are adjustably mounted on the legs of the first tripod. The first tripod forms a secure base on which the second tripod can be adjusted for height and for levelling.

Tripod arrangements

A partially rotated arrangement fastens parts together in nearly perfect alignment. The fasteners utilize semicircular rings which are rotated about the circular axis until each ring lies partly in each of two adjacent parts. The parts so joined together may contain one or more fluid passages or form electric conductors, and more particularly, wave guides.
