  • Method and device for regulating and optimizing transport of humidity by means of electroosmosis
    Publication number: 20040112747
    Abstract: In a method for regulating and optimizing transport of liquid in a porous structure by means of electroosmosis, a pulse pattern applied to one or more electrode pairs which are used during the electroosmosis is regulated by detecting a potential difference &Dgr;Vp over the electrode pair or electrode pairs during the duration t3 of a neutral pulse which forms part of the pulse pattern and subsequently regulating either the duration t3 of the neutral pulse or the duration Tp of the pulse pattern or both on the basis of the detected potential difference &Dgr;Vp and any change therein from measuring cycle to measuring cycle.

  • Method and device for regulating and optimizing transport of humidity by means of electroosmosis
    Patent number: 6126802
    Abstract: In a method for regulating and optimizing transport of liquid in a porous structure by means of electroosmosis, a pulse pattern applied to one or more electrode pairs which are used during the electroosmosis is regulated by detecting a potential difference .increment.V.sub.p over the electrode pair or electrode pairs during the duration t.sub.3 of a neutral pulse which forms part of the pulse pattern and subsequently regulating either the duration t.sub.3 of the neutral pulse or the duration T.sub.p of the pulse pattern or both on the basis of the detected potential difference .increment.V.sub.p and any change therein from measuring cycle to measuring cycle.

  • Method and apparatus for controlling the relative humidity in concrete and masonry structures
    Patent number: 5368709
    Abstract: In a method for eliminating humidity from concrete and masonry structures by means of electroosmosis, current pulses which are supplied in a determined pattern are used. The pulse voltage is limited to .+-.40 V. In order to generate the pulses and feed the electrodes a special electronic control device is used.
