  • Closed loop ionization apparatus for detecting trace gases
    Patent number: 5223712
    Abstract: A trace gas detector including in a closed gas loop, two baffle cells with an intermediate trace gas filter, each baffle cell consists of an ionization source, a labyrinth-like recombination zone and a collector electrode. A differential circuit derives a differential signal from output signals of the two baffle cells, the differential signal depending only on the trace gas concentration. Temperature changes and supply voltage changes are compensated by means of the differential circuit.

  • Method and arrangement of apparatus for frequency shifting a monochromatic narrow bandwidth light beam
    Patent number: 4264141
    Abstract: Arrangement for frequency shifting a monochromatic narrow-bandwidth light beam, in particular a laser beam, based upon the Doppler effect due to reflection from moving mirrors. Two stationary mirrors are provided between which the beam is reflected back and forth via two moving mirrors. The moving mirrors are staggered by an angle of 180.degree., arranged symmetrically on a rotating support and rotated about a common axis of rotation.
