Abstract: The present invention concerns a device for the transfer of a mechanical force to a piezo-electric element for the generation of an electrical signal corresponding to the mechanical force, e.g. the tension of a thread or the like and/or the movement of the same, wherein the piezo-electric element is positioned in a holder in order to be actuated by the mechanical force on the end surfaces.

Abstract: A system is provided for preventing gear hopout in a tooth clutch in a vehicle transmission, the tooth clutch including an engaging sleeve having sleeve clutch teeth. The tangent function for at least one of driving back-taper angle and braking back-taper angle is larger than the average value of clutch coefficient of friction and spline coefficient of friction multiplied by the sum of unity and the ratio of clutch teeth pitch diameter and spline teeth pitch diameter.

Abstract: A process such as a leaching, etching or pickling process which uses an aqueous acidic medium containing nitric acid is improved by carrying out the process in the presence of an oxidizing atmosphere in a closed contained.

Abstract: Quick-action attachment for working implements comprising a first coupling part disposed on the working implement or, for example, the operating arm of a working machine and having at least a pair of parallel, undercut, mutually facing surfaces, and comprising a second coupling part are disclosed. On the operating arm of the working machine or on the working implement and having a pair of parallel, bevelled, mutually outwardly facing surfaces are adapted to be brought into engagement with the undercut surfaces of the first coupling part.

Abstract: The invention relates to a catching hook having a straight portion (1) which in one end is provided with a hook (2) and another straight portion (3) which in the end opposite to the hook is provided with a handle (4). The portions are displaceable relative to one another between a catching position when they are extended at a maximum to a transportation position when they are pushed together. The hook (2) is rotatably connected to the end of the first straight portion (1), a locking device (6) being arranged in that end to prevent the rotation of the hook when used in its catching position, and after release permit rotation to a weighing position. The handle (4) is rotatably connected to a supporting device in the form of a sleeve (7) which is slidingly arranged on the corresponding straight portion, the handle being pivotably connected to the sleeve and after release from the end of the straight portion rotatable to a weighing position.
