Abstract: A system for transporting persons with reduced mobility includes a chassis having two lateral cross members, a device for connecting to an IV pole including a rod and a wheeled support attached to an end of the rod, the connection device including an attachment support fixed to the chassis, a coupling element designed to be solidly fixed to the rod, a member for connecting the coupling element to the attachment support, a lateral stop attached to at least one of the cross members, the lateral stop being built and arranged to brace the wheeled support in relation to the chassis and to position the IV pole laterally in relation to the transportation system.

Abstract: A process for the in-line inspection of the depth of a weld carried out by a welding beam pulse in which around its impact point on a workpiece, the beam pulse produces a welding plasma wherein, only during the emission of a welding beam pulse, at least one selected monochromatic emission line of the welding plasma is optically collected from the workpiece. The energy of said lines is converted into analog electrical signals and those signals are digitally processed with the resulting signals being compared with reference signals to produce an indication of the weld depth. Apparatus for performing this process is also disclosed.
