  • Wrench provided with an alternating current drive motor
    Patent number: 4517506
    Abstract: The invention relates to a wrench provided with an alternating current drive motor whose peculiarity is a medium frequency asynchronous motor (2) which is used as the drive motor with an associated device (7) for a frequency switching from the medium frequency to a lower line frequency. The mentioned device (7) is connected with a cycle control (8) from which it is switched off as soon as it receives the signal by means of a connected torque sensor (5) about the occurence of the setting moment on the screw joint made with the wrench.

  • Method for determining a measurement value proportional to the compression of an internal combustion engine
    Patent number: 4144746
    Abstract: A method for determining a measurement value proportional to the compression of an internal combustion engine, derived from the starter current, in which the a-c component of the starter current is integrated over the time between successive current minima and the difference between an integration value averaged over an engine cycle and integration values for individual cylinders obtained between succeeding current minima, is added, with the sign reversed, to the integration value for the next-following cylinder.
