Methods for sealing, detection and marking leaks in structural enclosures

Title: Methods for sealing, detection and marking leaks in structural enclosures

A system and method for detecting, marking and/or sealing building envelope leaks in buildings or any enclosed structure. Fogs of aerosolized sealant particles that have a surface tackiness that diminishes over time are introduced into the interior of prepared rooms. The surface properties of the aerosol particles can be controlled with the selection of sealant composition, including the presence and concentration of solvents, the range of produced particle sizes, and the relative humidity and temperature within the enclosure. A pressure differential is created and the micron scale particles adhere to the leak edges and to other particles as they are brought to the leaks and then leave the gas streamlines. Control of particle size, drying rate and particle residence time in the building interior allows control over the treatment area so that leaks are sealed without leaving a tacky residue.

Method for sealing remote leaks in an enclosure using an aerosol

Patent Modera, Mark P. ; Carrie, Francois R.

The invention is a method and device for sealing leaks remotely by means of injecting a previously prepared aerosol into the enclosure being sealed according to a particular sealing efficiency defined by the product of a penetration efficiency and a particle deposition efficiency. By using different limits in the relationship between penetration efficiency and flowrate, the same method according the invention can be used for coating the inside of an enclosure. Specifically the invention is a method and device for preparing, transporting, and depositing a solid phase aerosol to the interior surface of the enclosure relating particle size, particle carriermore »« less

Magnetic detection of underground pipe using timed-release marking droplets

Patent Powell, James R. ; Reich, Morris

A system 10 and method of detecting an underground pipe 12 injects magnetic marking droplets 16 into the underground pipe 12 which coat the inside of the pipe 12 and may be detected from aboveground by a magnetometer 28. The droplets 16 include a non-adhesive cover 32 which allows free flow thereof through the pipe 12, with the cover 32 being ablatable for the timed-release of a central core 30 containing magnetic particles 30a which adhere to the inside of the pipe 12 and are detectable from aboveground. The rate of ablation of the droplet covers 32 is selectively variablemore »« less

Methods and computer executable instructions for marking a downhole elongate line and detecting same

Patent Watkins, Arthur D.

Methods and computer executable instructions are provided for making an elongate line (22) with a plurality of marks (30) and detecting those marks (30) to determine a distance of the elongate line (22) in a downhole or a physical integrity thereof. In a preferred embodiment, each mark comprises a plurality of particles (44) having a substantially permanent magnetizing capability adhered to an exterior surface of the elongate line (22) at preselected intervals with an epoxy paint. The particles (44) are arranged at each interval as a plurality of bands (40). Thereafter, the particles are oriented into a magnetic signature formore »« less

Methods and apparatus for measuring the tightness of enclosures

Patent Modera, Mark P. ; Sherman, Max H.

Disclosed are methods and apparatus for measuring tightness of an enclosure such as a building by utilizing alternating pressurization techniques. One method comprises providing apparatus capable of causing an internal volume change for the enclosure, the apparatus including a means for determining the instantaneous volume change, and a means for determining the instantaneous pressure within the enclosure. The apparatus is operated within the enclosure to change the volume thereof, and at least one of the frequency and the displacement is adjusted to achieve a root mean square pressure in the enclosure approximately equal to a reference pressure. At that pressure,more »« less

Method and means of passive detection of leaks in buried pipes

Patent Claytor, Thomas N.

A method and means for passive detection of a leak in a buried pipe containing fluid under pressure includes a plurality of acoustic detectors that are placed in contact with the pipe. Noise produced by the leak is detected by the detectors, and the detected signals are correlated to locate the leak. In one embodiment of the invention two detectors are placed at different locations to locate a leak between them. In an alternate embodiment two detectors of different waves are placed at substantially the same location to determine the distance of the leak from the location.
