Abstract: An apparatus for anti-mine protection for an armored vehicle wherein a box (5) is mounted to the underside of the vehicle floor, with the box being completely filled in the longitudinal and transverse directions with a plurality of sandbag-like damping elements (4).

Abstract: An apparatus for the out-of-round circumferential machining of workpieces includes a tool holder, a tool bit carried by the tool holder and a motor having a rotor operatively coupled to the tool holder for a radial feed of the tool bit. The motor can be numerically and electronically controlled dependent upon a desired out-of-round contour of the workpieces. The moment of inertia of the tool holder, the tool bit and any other component moving with the tool holder as a unit during feed motion is at the most equal to the moment of inertia of the rotor.

Abstract: A method and apparatus for circumferentially machining an out-of-round workpiece in which the workpiece is rotated about its longitudinal axis at an irregular angular speed.

Abstract: An apparatus for the non-circular peripheral machining of an out-of-round workpiece includes a lathe spindle for rotating the workpiece; a radially displaceable tool holder for carrying a tool to engage a peripheral face of the workpiece; a first and a second setting motor for displacing the tool holder in a radial direction during rotation of the lathe spindle; a first connecting device coupling the output of the first setting motor with the second setting motor and the tool holder for displacing, with incremental steps, the second setting motor and the tool holder as a unit in the radial direction; and a second connecting device coupling the output of the second setting motor with the tool holder for displacing, with incremental steps--that are of different magnitude from those of the first setting motor--the tool holder in the radial direction relative to the first connecting device and the first setting motor.
