Abstract: An armored vehicle has front and rear sections pivoted together about a vertical axis. Each section has a pair of electrically driven wheels which can be selectively raised or lowered relative to their particular section. Hydraulic motors control the angular relation of the sections about their pivot axis. The front section mounts an elevatable gun and provides room for a crew and ammunition while the rear section carries a source of electric power for all the wheels.

Abstract: Stabilizing device for compensating by restraining the relative rocking movements between an articulated railroad car body and bogie running at high speed. The device comprises, longitudinally extending across the frame of the bogie a tube having sufficient stiffness for being free of any torsion, adapted to rotate inside bearings disposed at the extremities of the frame. The tube is provided at its extremities, with two parallel crank-arms integrally connected to the tube. The extremity of each of the crank-arms is articulated to a rigid connecting member which is attached on the other hand, by means of a swivel-joint, to a corresponding car body.

Abstract: Braking device for railroad bogie running at high speed, comprising a fixed part integrally connected to the frame of the bogie and a movable part suspended from the fixed part and adapted to be vertically displaced by suitable means towards a rail. The movable part is provided at its lower face with a series of electromagnets arranged above the rail. The series of electromagnets is flanked at each of its sides with a braking shoe adapted to be applied on the rail at the moment of braking in such a way that the electromagnets be placed at a relatively small distance from the rail. Means are provided for controlling the position of the braking shows as a function of the wearing of the shoe.
