Abstract: A self-propelled material handler has a pivotally mounted boom on a frame, and a cab that is positioned adjacent the side of the boom. The cab has an operator's entrance and exit opening on a side of the cab, that is positioned to permit an operator to enter and exit the cab and sit on a seat in the cab. A lateral restraint bar is mounted between the seat and the cab opening, and is movable to a working position where it obstructs the cab opening so that portions of the operator cannot be moved outwardly through the cab side opening from the interior, and which pivots to a raised position to permit an operator to pass through the cab opening. When the restraint bar moves away from its working position, a signal is provided to disable machine controls.

Abstract: The invention relates to a machine for harvesting berries, and particularly, grapes, comprising a straddling frame (1) on which are mounted two sets of shaking elements (4a, 4b), each on one side of the median plane of the machine, said shaking elements consisting of rods curved in an approximately horizontal plane and exhibiting their convexity in the direction of said median plane.Each end of each rod is jointed to a support mounted to pivot around an approximately vertical pin, drive members (12) being provided to move, in phase, the supports of rods located on the same side of the median plane so as to move the rods parallel to themselves, and to move, in phase opposition, the supports of the rods located on one of the sides of the median plane relative to the supports of the rods located on the other side of the median plane so that, when one of the sets of rods approaches the median plane, the other set of rods moves away from it.

Abstract: The present invention concerns a process for preparing ferrous parts of a color television tube and a furnace for operating such a process.According to the invention, each ferrous part behind the base of the television tube, is prepared in a single furnace and undergoes successively an annealing, a reduction and an oxidation in three parts of the furnace 3, 4 and 5, in such a way as to eliminate the mechanical stresses, remove the rust and deposit homogeneous and adhesive layers of iron oxides I and II.
