  • Patent number: 7222659
    Abstract: A heat management system include including application of phase change materials (PCM). A heat or cold storage multistage tower has a housing with a multistage system of flat rigid container. A significant fraction of internal space of each container is filled with PCM; these containers are fabricated from ceramics, glass, glass ceramics or sulfur concrete. Another version of the heat or cold storage tower is based on application of multi-channel blocks from ceramics, glass, glass ceramics or sulfur concrete; the parallel internal vertical channels of the blocks are open and sealed at their bottoms alternatively, and the channels with the sealed bottoms are filled partially with PCM. The tower achieves effective heat transfer between a heat transfer fluid (HTF) and PCM in the processes of charging and discharging of the containers with heat or cold.

  • Publication number: 20070027444
    Abstract: The invention proposes a cryosurgical instrument and its accessory system operating on the base of a refrigerant evaporation. The invention comprises combination of some technical solutions. Flow in a central lumen of the cryosurgical instrument has oscillating character; the refrigerant is provided on the internal surface of the distal cryotip in the form of separated portions. 2. The internal surface of the distal cryotip of the cryosurgical instrument is covered by a porous coating, which soaks completely one portion of the refrigerant. 3. Vapors obtained as a result of the refrigerant boiling on the porous coating of the cryotip are removed through the central lumen into the atmosphere. Combination of these technical solutions allows to construct a safely cryosurgical instrument with high freezing power and small outer diameter. The proposed cryosurgical instrument may be designed as a flexible cryocatheter or as a rigid cryoprobe.

  • Patent number: 7137978
    Abstract: The invention is directed to a cryosurgical instrument and to an accessory system operating on the base of refrigerant evaporation, wherein the portions of the refrigerant are periodically provided to the distal cryotip of the cryosurgical instrument via a central lumen thereof. The internal surface of the distal cryotip is preferably covered by a porous coating capable of soaking at least one portion of the refrigerant. The vapors obtained as a result of the refrigerant boiling on the porous coating of the cryotip are preferably removed through the central lumen of the cryosurgical instrument into the atmosphere. These features may be combined to construct a cryosurgical instrument with relatively high freezing power and small outer diameter which may be designed as a flexible cryocatheter or alternatively as a rigid cryoprobe.

  • Publication number: 20060196358
    Abstract: The invention proposes a method of destruction of volatile organic and inorganic compounds in wastewater, this method includes following stages: stripping the aforementioned volatile compounds in a stripping-chemisorption column; preliminary heating the gaseous medium containing these volatile compounds in a first heat regenerator; thermal, flare or thermo-catalytic oxidation of the volatile compounds in circulating gaseous medium; cooling the gaseous medium in a second heat regenerator; chemisorption of acidic gases from the gaseous medium in the stripping-chemisorption column with stripping at the same time additional amount of the volatile compounds from the wastewater. After specific period, direction of the gaseous medium flow is alternated. The proposed method can be executed at elevated temperature. The invention includes as well systems realizing the proposed method.

  • Publication number: 20050206675
    Abstract: Embodiments of the present invention provide a self-cleaning print head for an ink jet printer that directs ink to a substrate to be marked. The print head includes a ground plate having a channel formed therethrough, and a makeup fluid supply system that supplies makeup fluid directly to the ground plate through a makeup supply conduit, and into a catcher. The makeup fluid removes ink residue from the channel as the makeup fluid flows through the channel.
