  • Patent number: 4833385
    Abstract: A method for the phase synchronization of step-drive-controlled equipment, in particular of optical modulation devices for multiple-beam spectrophotometers.Starting with the phase comparison of a synchronization signal formed from a sensor signal produced by a fixed phase difference from information signals of the device, the phase relationship of the commutator signals of the stepping motor is controlled with a predetermined reference signal.

  • Patent number: 4831319
    Abstract: A method for the phase synchronization of equipment controlled by stepping drives, especially optical modulating systems for multiple-beam spectral photometers. Each time that the equipment is started up, a reference signal is made synchronous with a synchronizing signal which is derived from a sensor signal of the apparatus which is locked in phase with the intelligence signal. For a purely electrical correction the phasing between the intelligence signals and the synchronizing signal is set once. In the event of a phasing error between the synchronizing signal and the reference signal the reference signal is reset.
