Definitions
- the invention relates according to a first inventive idea Method for dehumidifying and / or desalting structures by applying with the beat of a first low-frequency Signal successive sequences of a high-frequency, by appropriate voltage application at least one Coil generated, electromagnetic vibration, their frequency is in the range of 141 kHz and their amplitude is in the range of each Sequence preferably decays exponentially, and goes according to a Another idea of the invention to a preferred device for Implementation of this method with a building associated, at least one coil containing transmitting device, which contains a preferably an oscillator Vibration generating device with a high-frequency Oscillation exporting voltage can be acted upon by means of a modulator consecutive, damped sequences are imprinted by modulation of a high-frequency signal be formed with a low-frequency signal through a the modulator upstream, a square wave processing Differentiator is formed.
- the length of successive sequences can be expedient be changed periodically. This facilitates the device technology Realization.
- the period length can be at least comprise four, preferably ten full sequences. this makes possible a gradation in comparatively large stages and results at the same time a sufficiently long period.
- the vibration level of the high-frequency vibration in preferably equal intervals are changed.
- This will the desired irregularity and thus the mode of action yet elevated.
- the change in the vibration level of the high-frequency oscillation to the beat of a second low-frequency Signals take place.
- This can be a square wave signal act, wherein at each rising or falling edge of a Change can be made.
- the frequency can be so be chosen that the distance of the changes of Vibration levels of the period length of the Corresponds to sequence change periods. This results therefore with the beginning of each period also a change of the Vibration levels, which gives a particularly good effect can be.
- Another, particularly preferable measure to increase the dehumidifying effect can be advantageously that in the vicinity of the structure a potential sink with respect of existing in the building potential is generated.
- a potential sink with respect of existing in the building potential is generated.
- the Moisture is usually dissolved salts, so that ions arise, where the moisture attaches. These particles are attracted by a potential well depending on their charge.
- the creation of a potential sink is therefore a directed Movement of the particles pushed by the vibrations and an acceleration of this movement accomplished.
- the modulator with another, low-frequency signal are applied.
- this signal can be applied to the coil of the transmitter voltage in the Clock of this signal to be changed abruptly.
- a further advantageous measures may be that the Signal generating device a power supply with upstream power transformer is assigned, the power supply two DC outputs for plus and minus, over which the signal generating means and the transmitting device can be supplied with positive and negative voltage and optionally to form a potential well with a at least in the vicinity of the structure in the earth insertable ladder are connectable.
