Abstract: A wheel load indicator comprises a rectangular flat plate (1) of a light material having measuring properties. A series of recesses (4) forming webs (5) are provided along two lateral edges (6) of the plate (1). Strain gauges (12) are adhesively bonded to walls of bores (10) in the area of the webs (5) to determine the shearing stress under the load of a wheel (100) which has driven on the bending portion (3).

Abstract: A stabilizing and aiming drive for the turret (2) of a vehicle (1) comprises brake surfaces at revolving rings (6,7) which are supported for rotation at the vehicle superstructure or at the turret. The revolving rings (6,7) are driven in opposite directions by an electric motor (20) acting through driven pinions (23,24), and they carry brake surfaces (10,11). These brake surfaces face the friction linings (12,13) which are adapted to be acted upon by magnetic structural units (16,17) provided at the turret or vehicle superstructure for engagement with the brake surfaces, in order to thereby apply controlled stabilizing and aiming moments on the turret.

Abstract: System for positioning and maintaining position stabilization of a mass such as a barrelled gun supported on a base such as a tracked vehicle. The system employs oppositely rotating disks with fluid actuated clutches for moving the gun barrel mass in a single degree of freedom as determined by a deviation from a predetermined setting.

Abstract: In an endless track having chain links which comprise tubular bodies arranged transverse to the direction of movement and connected to the adjacent chain links, as seen in the direction of movement, by connector links as well as rod members which extend through the connector links and through the tubular bodies, the tubular bodies and, if desired, the connector links of each chain link being so dimensioned, transverse to the moving direction, that they support each other laterally from a certain given flexure of the chain link on.

Abstract: An endless track having chain links which comprise tubular bodies connected by connector links to the adjacent chain links, as seen in the direction of movement, is widened by at least one further tubular body and one further connector link, all tubular bodies and connector links preferably being of uniform basic dimension.

Abstract: This invention relates to an endless track having chain links which are connected by connectors as well as rod members extending through the connectors.A connection between the connectors and rods is provided by clamping contact surfaces on the rods and connectors in abutment with other, at least one of said contact surfaces comprising at least one depression arranged around the circumferential area of the bolt or connector contact surface, whereby a friction lock preventing the bolts from moving axially and/or rotating with respect to the connectors is achieved.

Abstract: The invention relates to an apparatus and method for optical tracking and aiming from a movable system, such as a vehicle. The apparatus may comprise a viewing device having a sighting mark moveable responsive to the position of an aiming mechanism control. The sighting mark may be superimposed on a field of vision observable in the viewing device, by stroboscopic illumination.

Abstract: The invention relates to a force sensing device which is to be inserted in a force transmitting structural member, like a rope, especially a rope for lifting a jib or a load of a crane. The force sensing device has a flat body provided with weak locations at which strain measuring devices are fixed. The flat body is dimensioned with respect to a high degree of safety against overload, to high duration working stability and reproducibility as well as to a simple and cheap production.
