Patent FR-2544705-A1 (FR)
Title: Single rope arrester mechanism
Inventor: SUNDERHAUS HUBERT
IPC: B66B19/02
Filed: 1984-03-22
Abstract: The single-rope arrester mechanism grips a vertical rope run  in a mine shaft by means of wedges in one direction and frees it in the other. The inclined faces of the wedges are supported by loose rollers whose spindles work in guides in the housing side plates. Each spindle is secured at both ends in the side plates, one of which is divided into halves so as to enclose a rope-insertion slot open at one end opposite the one-piece side plate. These plates are fixed and supported on a one-piece baseplate, recessed to form a slot extension. One driving lever is mounted in bearings on each side plate half, having an arm supported on a bracket plate of the respective wedge, and which protrudes through an opening on the side plate half.

Title: Multihull sailing craft
IPC: B63B1/14
Filed: 1985-12-03
Abstract: The invention relates to a device for a craft carried by three tapered floats F of little drag, arranged in a (preferably isosceles) triangle and whose axis of symmetry is the direcion of forward travel. These three floats are joined together by a structure S which is itself in the shape of a triangle and rests via its corners on the centres of gravity of the floats and by means of articulated connections. These articulated connections provide the floats with the freedom for pitching movements and provide the lateral floats with a partial freedom for yawing movements. The float placed in the central axis of the craft may be either at the bow or at the stern and is in all cases orientable so as to be used as a rudder. This orientation of the float may be obtained by acting on a rudder blade placed at the rear of this float with a view to limiting the forces required for steering.
