    Abstract: A rotatable vent assembly system for areas where breathable airflow is required is disclosed herein. The rotatable vent assembly system improves airflow in any structure where breathable airflow may be a concern, including but not limited to air vacuum vaults, valve vaults, water tanks, pressure reducing valve units, or other confined structures. The rotatable vent assembly system helps reduce frost accumulation within riser pipes during winter months and improves breathable air within confined spaces. By reducing the accumulation of frost, the potential for pipe breakage is reduced, also reducing maintenance and replacement costs to municipalities and property owners for burst pipes. Rotating the vent control component at the top of a riser pipe connected to a pipe system controls the flow of breathable air by increasing or reducing airflow within the pipe system.

The pipe would not deform significantly from that having the squashed circle cross section under the condition in which the inside pressure is the same or less than that of the internal pressure of the pipe that carries ordinary cold tap water. The cross section of the pipe gets deformed to become rounder and larger when the water within the pipe is frozen, and the rounder and larger cross section is large enough for the pipe to contain the frozen water or ice without having any damages.

  • Patent number: 7278549
    Abstract: A liquid cooling system utilizing minimal size and volume enclosures, air pockets, compressible objects, and flexible objects is provided to protect against expansion of water-based solutions when frozen. In such a system, pipes, pumps, and heat exchangers are designed to prevent cracking of their enclosures and chambers. Also described are methods of preventing cracking in a liquid cooling system. In all these cases, the system must be designed to tolerate expansion when water is frozen.

  • Patent number: 6978825
    Abstract: The present invention relates to a device for the heat insulation of at least one underwater pipe (1) intended to be laid on the sea bed at great depth, comprising an insulating coating surrounding the latter and a protective envelope (3), characterized in that said insulating coating comprises a virtually incompressible liquid/solid phase change material (4) with a melting temperature T0 higher than that T2 of the medium surrounding the pipe in operation and less than that T1 of the effluents circulating in the pipe, and said material (4) preferably being impregnated in an absorbent matrix (2) surrounding the pipe (1), preferably nearest its outer surface, which protective envelope (3) is resistant and deformable and ensures a containment against and about said insulating coating.

  • Patent number: 6976809
    Abstract: A method for maintaining a stable soil by surrounding a chilled gas pipe with a material that has an antifreeze component that prevents the soil from freezing. By keeping the soil from freezing, it remains stable at all times. The method calls for excavating a trench, lining it with a geotextile membrane that keeps water from infiltrating into the trench, and then surrounding it with a bed of limestone (calcium carbonate) that is mixed with calcium magnesium acetate (CMA), which acts as an anti-freeze agent. The limestone-CMA mixture surrounds the pipe. The trench is covered by another geotextile membrane to completely seal it. In this way, the pipeline is surrounded by a material that is not subject to freezing. As such, it provides a stable bed for the pipeline to prevent frost heaving.

  • Patent number: 6948509
    Abstract: A hydrant comprising a chamber forming a reservoir, an inlet configured to supply fluid to the hydrant and a sleeve configured to force static fluid out of an outlet, wherein a first portion of the chamber containing the reservoir is configured to be located in the ground below a frost line and a second portion of the chamber is configured to be located above the frost line, wherein the static fluid is forced to exit the outlet above the ground and residual fluid is trapped in the reservoir inhibiting freezing when the sleeve moves to a first position, and when in a second position the sleeve is configured to allow supply fluid to exit the outlet through the reservoir, thereby purging the reservoir of residual fluid.

  • Patent number: 6939082
    Abstract: The method of taking a remotely operated vehicle to the ocean floor to land on and move along a subsea pipeline above or below the seafloor and repeatedly circulate seawater which has been heated electrically, mechanically, or chemically across the outer surface of the pipeline to melt hydrates or paraffins which have formed on the inside of the pipeline.

  • Patent number: 6883534
    Abstract: A freezeless wall hydrant has a normally horizontal fluid inlet tube with an interior end and exterior end. A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A valve seat is located on an interior end of the valve fitting. A valve body is longitudinally movably mounted in the inlet tube adjacent to the valve fitting. A pressure relief valve is mounted on the inlet tube between the interior and exterior ends thereof so that if residual water within and adjacent the exterior end of the inlet tube freezes and exerts pressure on residual fluid within the inlet tube adjacent the interior end thereof, the pressure relief valve will actuate to purge some of the high pressure fluid to decrease the pressure being exerted by such fluid to the interior of the inlet tube.

  • Patent number: 6857442
    Abstract: A freezeless wall hydrant has a normally horizontal fluid inlet tube with an interior end and exterior end. A hollow valve fitting is rigidly secured to the interior end of the inlet tube for a connection to a source of pressurized fluid. A movable ball is located with a fluid conduit that extends from the interior of the inlet tube to the location of the potable water source. When the water pressure inside the inlet tube increases because of the presence of ice, the high pressure of such water moves the ball to open fluid flow of the high pressure fluid to the source of potable water which will be at a lower pressure, thus reducing the fluid pressure within the inlet tube and saving it from rupture.

  • Patent number: 6830063
    Abstract: A freezeless wall hydrant is provided that has an elongated inlet pipe comprised of a hollow tube. The tube is connected to a valve and fitting assembly on its inner end for connection to a source of water under pressure. On the outer end, the tube is connected to an adjusting element with an outlet port that is associated with the valve and fitting assembly to open or close the tube to fluid flow and allow for fluid flow out of the tube when the valve is in the open position. The tube is comprised of a flexible material that enlarges in diameter in an area along its length when it is subjected to trapped fluid therein under high pressure so that the tube will not rupture. The tube returns to its normal diameter after the high fluid pressure therein is abated.

  • Patent number: 6830062
    Abstract: A dripper apparatus for a water spigot includes a coupler having a threaded female member for connecting to a water spigot. A generally cylindrical elongate member has a longitudinal portion in fluid communication with the female member. The longitudinal portion has an upper portion that defines a seat within the female member. A flow controller sits on the seat. A filter screen upstream the flow controller collects particles in water flowing therethrough so that the controller does not become clogged. The flow controller includes a housing that is provided with an upper inlet for receiving a first flow rate of water from a water spigot. The housing also includes a cavity therewithin and the cavity is in fluid contact with the upper inlet. A flexible membrane is housed within the cavity and floats when water enters the cavity via the upper inlet. The upper inlet is slotted at the top thereof for further filtering water flowing therethrough.
