Abstract: A single ended filly encapsulated water cooling cartridge for thermoelectrically cooling fluids has a vertically mounted cylindrical water flow pipe with a plurality of flat sides and acting as a cold plate communicating with an inlet of the water cooling cartridge, a like plurality of heat sinks circumferentiary positioned around the water flow pipe with longitudinal fins extending radially outwardly from each heat sink, a cylindrical shell enveloping the heat sinks and the water flow pipe and forming an annulus air passageway therein, an axial forced air fan mounted on the top of the water cooling cartridge to induce air flow along the heat sinks, thermoelectric elements acting as heat pumps positioned between the heat sink and the water flow pipe, and a temperature control thermostat.

Abstract: A water treatment device for purifying small quantities of non-potable water for drinking purposes. The device includes: a primary container, a secondary product container, and a cylindrical filter cartridge. The primary container is filled with untreated water, and brought into contact with a disinfecting agent. The filter cartridge is then attached to the primary container and the secondary container is attached to an outlet port of the filter cartridge, the entire arrangement is then inverted to allow water to flow from the primary container into the inlet port of the filter cartridge. A physicochemical time switch is installed near the inlet port of the filter cartridge and blocks the flow of water from the primary container into the filtering elements until an appropriate amount of time has lapsed for the disinfecting agent to effectively disinfect the water. The physicochemical time switch is either a water dissolvable barrier or an expandable compartment filled with hydrophilic polymeric crystals.

Abstract: A safety liquid level sight gauge with a transparent sight tube coaxially disposed between mounting blocks and concentrically within a transparent shield tube which is protected by a metal sleeve with a sliding inspection window for observing the liquid level therein. The gauge includes a sight tube breakage shut off system, and a leak shut off system. The breakage shut off system includes the transparent sight tube coaxially aligned between a pair of check valves within each mounting block. A check valve push rod is concentrically disposed and supported within the bore of the sight tube and urges both check valves to an open position allowing liquid to enter the bore of the sight tube. When the push rod collapses, such as when the sight tube is either cracked or broken, the check valve move to a closed position.

Abstract: Sequential DAF apparatus and methods providing zero pool and nonmechanical waste material removal are disclosed which include a number of floatation tanks each arranged to operate either independently or sequentially, each tank has a conical shaped bottom with a centrally located port at the lowest vertical position of the tank, each tank is fitted with a number of valves and plumbing which allows an operator to fill each tank with waste water charged with dissolved air through the central port which is then retained during a floatation period to allowed waste material to separate from clarified water in the tank. Clarified water and waste material is removed from the bottom of the tank through the central port. Water clarity sensors are positioned in the tank near the central port. A final rinsing step may be included to assure all floated material is removed from the tank before refilling.

Abstract: A counter top reverse osmosis water purification system, suitable for home use, is connected to a water supply and contains a closed fluid treatment circuit extending to a water outlet. The closed fluid circuit flows through a plurality of replaceable water treatment modules mounted on a flowboard and each having a specific water treatment function, such as the removal of a particular material from the water by the use of reverse osmosis, filtration, carbon adsorption, ion exchange or the addition of a chemical to balance the desired water conditions. Preferably the circuit also includes traversing a radiation device, for example an ultraviolet light, for the purpose of sanitizing the water.

Abstract: A modular water treatment and purification system, suitable for home use, is connected to a water supply and contains a closed fluid treatment circuit extending to a water outlet. The closed fluid circuit flows through a plurality of replaceable water treatment modules each having a specific water treatment function, such as the removal of a particular material from the water by the use of filtration, carbon adsorption, ion exchange or the addition of a chemical to balance the desired water conditions. Preferably the circuit also includes traversing a radiation device, for example an ultra violet light, for the purpose of sanitizing the water.

Abstract: A method and system for automatically verifying the function of pressure and vacuum relief valves for low-pressure storage vessels and tanks, which can be remotely operator actuated to insure venting when emergencies occur, allows for on-line verification of the relief valve functionality and proper operation. The system periodically checks the set pressure of the valve by attempting to lift its pallet and measures the deviation from a set point. It also indicates unplanned occurrence of valve lifting, as a result of unforeseen upset in storage vessel pressure. This apparatus is electrically operated and controlled and relies on electromagnetic means for tractive or pull-force, as well as for detecting valve lifting.

Abstract: A method and system for treating and purifying water on site provides a cascade series of alternating cation and anion beds with flow control controlling flow of water in a first direction to flow through all beds in sequence, to purify the water, and controlling back flow through only like ion resin beds to regenerate the resins contained therein. The subject system removes impurities which are ionic and dissolved in the water.

Abstract: A liquid transfer method and apparatus has primary and secondary transfer lines, wherein the primary line carries fluid being moved from a supply container through a transfer assembly to a receiving container, and the secondary line carries pressurized inert gas to substantially purge liquid from the primary line. Pressurized gas is admitted into the system upon actuation of a liquid level sensing float valve in response to the liquid level in the transfer device. The pressurized gas actuates the closure of a valve on the primary line near the receiving container. The pressurized inert gas proceeds to force residual liquid out of the primary lines into the secondary lines and into the receiving container. Manual inspection and valve actuation is used to terminate gas flow and complete the purging process.

Abstract: Mounting assemblies for filter cartridges include a sealing bolt having a threaded shank portion for being threadably engaged with one (upper) end of an interior apertured filter cartridge support post. A head portion of the bolt allows it to be turned manually by a suitable tool to assist in threadably interconnecting the shank and post. The other (lower) end of the support post is rigidly connected (e.g., via welding) to a lower external sealing cup-flange which sealingly bears against a lower end gasket associated with the filter cartridge. The sealing bolt is further provided with an upper sealing cup-flange positioned concentrically around the shank portion immediately below the head portion of the sealing bolt. An O-ring seal is embedded in the lower surface of the head portion so as to sealingly bear against the upper sealing cup-flange when the sealing bolt is threadably tightened with respect to the support post.
