  • Process for the removal of impurities from exhaust gases
    Patent number: 4835974
    Abstract: The removal of impurities from exhaust gases takes place by cooling the exhaust gas by means of a circulation gas and condensing out of the impurities in two groups of reversible heat exchangers. Each group consists of two precoolers and one low temperature cooler. While the impurities condense out in one group, they are thawed in the other group. In order to simplify the control, only one precooler is used in each group, which is charged with two inside gases, namely, the exhaust gas and the circulation gas. Only two simple control systems which can be easily program-controlled are then required for the purification process. In addition, the temperature increase of the circulation gas in the circulation gas blower can be utilized for heating up purposes in the group to be thawed.

  • Process for the electrical excitation of a laser gas
    Patent number: 4780881
    Abstract: In order to prevent, in the microwave excitation of a laser gas, the development of wall boundary layers and to attain a homogeneously large volume plasma, the laser gas is delivered in the inclusion zone of the microwave after passing a current-forming element where it is ignited by a coaxial wave guide arrangement. The ignited laser gas then spreads with the microwave in the discharge segment where it produces a homogeneous, excited laser-active medium. The homogeneity is additionally improved with the operation of the microwave guide near the "cutoff-width".
