    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.

    Abstract: Device for synchronous modulation, synchronous light-path switch-over and control-signal derivation for step-drive controlled modulation and switch-over devices, especially for multibeam spectral analysis equipment and preferably for the infrared region of the spectrum, in which the radiation modulation is effected by a rotating light stop and the light path switch-over between a measuring beam and a reference beam is effected by pivoting mirrors. The device provides for the use of only a single photosensor. The synchronization between the stepping motor for moving the light stop and the stepping motors for moving the mirrors is effected via a counting logic and common clocking. Moreover, set pulses are generated to set the mirrors in defined positions, and control signals are generated for further processing.

    Abstract: An apparatus for intermitting beams of light for use in a gas analyzer in which a rotary shaft of a chopper is supported by first and second ball bearings. An outside ring of the first ball bearing is fixedly mounted on a bearing housing and either an inside ring or an outside ring of the second ball bearing is adapted to be movable in the thrust or axial direction relative to the rotary shaft, whereby the second ball bearing is movably energized in the thrust direction by an elastic member to eliminate shake of the rotary shaft due to play in the ball bearings and thus reduce modulation noise to improve measuring accuracy of the gas analyzer.

    Abstract: The object of this invention is a double multichromatic photometer including a single light-source and a single detector, particularly for the determination of chemical and clinical analyses, in which the photometer light comes from a single light-source which radiates along three distinct optical paths that converge onto a single detector; two of the optical paths are the first and the second measuring channels, which are alternatively excluded whereas the third optical path is for reference purposes. An optical collimation assembly and a measurement cuvette are inserted into each of the two measuring optical paths or channels. Within said three optical paths is inserted a rotating drum, said drum holds a number of interference filters, allowing the third reference optical path to pass freely, and inserts one filter at a time into one or the other of the two measuring optical paths. Moreover, a rotating shutter controlled by a motor is also provided for the reference optical path, said shutter coordinately rotates with the filter-bearing drum. An opto-electronic assembly, including printed circuit boards and optical couplers are provided for the selection of filters and the measuring channel.
