Abstract: The invention relates to a system for fixing an object in the ground, comprising at least one fixing peg (10) and means for carrying out the above. The peg (10) comprises a tube (14) and at least two lugs (28) on the lower end of a central support rod (24). An axial tension acting on the rod (24) which runs axially in the tube (14) and is fixed in rotation therein, causes the lugs (28) to deploy through openings (30) in the tube (14), such as to cause the extension thereof in the direction of tension at an angle to the length of the tube (14). An operating mechanism (33) comprises a threaded pin (36) with a screw (40) pressing on the head of the tube. The lower end of said threaded pin (36) is coupled to the upper end of the central support (24) in order to transmit an axial tension thereto on turning the screw (40) in a first direction.

Abstract: A device for unpiling sheets one at a time from a pile of sheets placed perpendicular to a supporting surface, includes a pressure arm engaging a first face of the pile. A single friction drive roller has an axis perpendicular to the supporting surface, arranged at a predetermined distance from the supporting surface. The second face of the pile is engaged with the roller along a first edge. A low-friction abutment is arranged in the vicinity of the roller, separated from the supporting surface by the roller and has a surface parallel to the roller axis and offset relative to the roller. A pad is disposed substantially perpendicular to the supporting surface and is movable towards the abutment along a second edge located downstream of the first edge.

Abstract: The invention relates to a reader-encoder of an magnetic card, which comprises means for maintaining the support in a fixed and well determined position in contact with read-write means disposed on a carriage moving in a uniform rectilinear movement. It comprises means for orienting the read-write means with respect to the magnetic track of the support and drive means associated with two transmission belts, one elastic, the other rigid. The reader-encoder is employed for magnetic cards used in banks.
