20150136368 | HEAT EXCHANGER - A heat exchanger includes a housing and a fluid flow conduit located within a cavity formed in the housing, the fluid flow conduit including an outer tube located adjacent to an inner wall of the housing and an inner tube in fluid communication with the outer tube, the inner tube being located between the outer tube and a longitudinal axis of the housing. An inlet port is located on the housing, the inlet port being in fluid communication with the cavity. The heat exchanger includes an outlet port located on the housing, the outlet port being in fluid communication with the cavity. | 05-21-2015 |
20130331265 | BIOCIDAL COMPOSITION FOR TREATING WATER - An aqueous composition for treatment of water comprising: (a) an N,N-dimethyl-2-hydroxypropylammonium chloride polymer; (b) lanthanum chloride; and (c) a dimethylamine epichlorohydrin ethylenediamine polymer; and a method of treating water using the composition. | 12-12-2013 |
20130284647 | WATER TREATMENT SYSTEM - An apparatus for treating water stored in a reservoir to remove contaminants has a feed line for receiving water and a by-pass valve that controls the flow of water through the feed line. A venturi valve responds to the rate of flow of water through a flow line by creating a vacuum in a supply line from an ozone generator, the extent of the vacuum created being dependent on the rate of flow, to add ozone at a controlled rate to the water to be treated. A sensor probe measures the oxidation reduction potential of the water, to supply hydrogen peroxide to the water at a controlled rate dependent on the oxidation reduction potential level. The ozone and the hydrogen peroxide are mixed with the water in a multicyclone unit to allow a peroxone reaction to occur that treats the water, and the treated water is returned to the reservoir. | 10-31-2013 |
20130118960 | MULTI-CYCLONE SEDIMENT FILTER - A multi-cyclone sediment filter having a housing with upper and lower shells and defining an interior space for fluid flow. A cyclone holder is disposed in the housing and includes a plurality of fluid cyclones, each comprising a conical tube with a small opening at a lower end and a larger opening at an upper end. A fluid inlet introduces fluid into the filter housing. A fluid outlet in fluid discharges fluid. A manifold plate is disposed above the cyclone holder and includes a plurality of diffuser tubes, each extending downwardly into an upper end of one of the fluid cyclones. Fluid flowing from the fluid inlet is directed into a diverter cone under the manifold plate and is diverted outwardly between the manifold plate and the cyclone holder, into the fluid cyclones, outwardly through the diffuser tubes, and then out through the fluid outlet. | 05-16-2013 |
20110073105 | MODULAR THERMAL WATER SOLAR PANEL SYSTEM - A modular thermal solar panel water heating system with a plurality of solar heating modules, each including a inlet manifolds and outlet manifolds and a thin tube array disposed between and in fluid communication with the inlet and outlet manifolds. Mounting and clamping apparatus attach the solar heating modules to a surface and providing secure clamping pressures on clamped elements even as clamped elements expand and contract. Fittings provide a watertight coupling between adjoining modules and bring each module into fluid communication with at least one adjoining module. In a panel array, one module includes a water inlet for connection to a source of water under pressure and another module includes a water outlet. A set of plugs are disposed on the manifolds in a configuration that ensures that water introduced into the water inlet flows across at least one thin tube array before exiting the water outlet. | 03-31-2011 |
20100213118 | MULTI-CYCLONE SEDIMENT FILTER - A multi-cyclone sediment filter having a sediment bowl with a hemispherical bottom and a sump for collecting sediment, a cylindrical cyclone housing disposed above and sealingly connected to the sediment bowl, a removable and replaceable cyclone cartridge inserted into the cyclone housing, a diffuser plate sealingly connected to the cyclone cartridge and cyclone housing, a fluid inlet for introducing fluid into the cyclone housing, and a fluid outlet for discharging fluid from the cyclone housing. The cyclone cartridge inserted in the cyclone housing includes a plurality of vertically disposed inverted cone-shaped fluid cyclones, each having a small opening at a lower end and larger opening at an upper end. The cartridge has a plurality of fluid flow paths that direct fluid to the cyclones where a vortex is induced in the moving fluid. As sediment is removed from the fluid in each cyclone, it is separated out and delivered down into the sediment bowl sump, while fluid is directed upwardly and out to the fluid outlet. | 08-26-2010 |
