  • Patent number: 10092810
    Abstract: A golf putting aide, that can be used as part of an independent game using golf equipment, which aide has a large annular platter with a series of evenly spaced spokes thereon on the upper side, and slip impeding means on the underside. Each spoke, is radiused on both side faces thereof, to match the curvature of a golf ball, such that on impact a golf ball will roll down the spoke toward a center opening in the platter rather than ricocheting off at an angle of incidence post impact. The spokes of the preferred embodiment taper inwardly from the rear surface toward the front surface, evenly on both sides of a center line, and taper downwardly along the top surface from the rear surface forwardly to the front. The device may be used at home on grass, at miniature golf locations or on a golf course hole with permission.

  • Patent number: 9957201
    Abstract: A biogas plant produces both methane and liquid fertilizer by fermenting biomass. The plant includes a fermenter, a percolate tank and a sanitation tank located inside the percolate tank. Dry fermentation takes place in the fermenter and generates methane and a percolate. The percolate is circulated between the fermenter and the percolate tank. Percolate that is returned from the percolate tank to the fermenter is sprinkled over the biomass. A portion of the percolate is transferred from the percolate tank into the sanitation tank. The percolate in the sanitation tank is sanitized by heating to a Celsius temperature between 45° and 65° for a period of at least five days. The percolate in the sanitation tank is heated using both a heating device in the sanitation tank as well as heat generated from a thermophilic fermentation reaction occurring in the percolate tank. The sanitized percolate is used as liquid fertilizer.

    Abstract: Radioactive strontium is efficiently removed from wastewater containing radioactive strontium. In a treatment method for radioactive strontium-containing wastewater, wastewater containing radioactive strontium and a powdery alkali metal titanate are mixed in a stirrer-equipped reaction tank by stirring such that radioactive strontium in the wastewater is adsorbed on the powdery alkali metal titanate, followed by subjecting the powdery alkali metal titanate having radioactive strontium adsorbed thereon to solid-liquid separation. The radiation dose of treated water can be effectively reduced in such a manner that a powder of an alkali metal titanate is directly added to radioactive strontium-containing wastewater and is dispersed therein and therefore radioactive strontium is efficiently removed by adsorption.

Biological species in the bioreactor tank consume gas and perform bodily functions that converts dissolved waste into easily removable carbon dioxide and suspend solids. Gas consumed by the biological species is replenished by pumping the wastewater though a liquid-gas mixer.

  • Publication number: 20100032370
    Abstract: An apparatus for the anaerobic digestion of solid waste is disclosed. The apparatus includes a pre-digestion treatment chamber and an anaerobic digester chamber coupled to the pre-digestion treatment chamber. A liquid suspension of solid waste is pretreated under aerobic conditions by heating to a desired pre-digestion temperature. One or more chemical or biological additives are added to the suspension of solid waste to improve the anaerobic digestibility of the solid waste. This may include enzymes to destruct poorly digestible solids and/or materials to provide a desired C:N ratio in the solid waste. The apparatus may include mixers, heaters, chemical or biological additives as needed, various sensors and probes, and a control system to monitor and control the anaerobic digestion process and maintain microbial health of the digester.

  • Publication number: 20090294381
    Abstract: The invention relates to the control of pH in water where hydroxyl ions are being produced by adding to the water an amount of transition metal salt sufficient to bind with hydroxyl into a slightly soluble or insoluble reaction product, thereby removing sufficient hydroxyl ion from the water to lower the pH thereof. This technique is particularly suitable for pH control in pool or spa water that is sanitized using chemical or electrolytic chlorination, where the sanitation process causes the pH in the water to rise. The invention also relates to apparatus for dispensing water treatment materials to water, and to methods for controlling phosphate levels and algae in water.

  • Patent number: 7615147
    Abstract: A water treatment device that chemically treats tidal water. The water may, if desired, be salt water or fresh water. The water treatment device is substantially cylindrical with paddles extending outward from central hubs. The paddles are T-shaped and are perforated. The perforation aids in water treatment by aerating the water as the tide movement turns the paddles. The water treatment device has a central perforated tray that is slidably insertable into the central hubs. The central hubs are open in the center to permit the aerated water from the paddles to come in contact with the water treatment chemicals in the central tray. The perforations of the central tray allow the water treatment chemicals to come into contact with the surrounding area to treat the tidal water.

  • Patent number: 7553413
    Abstract: A plasma concentrator of this invention having a concentrator chamber, concentrator gel beads, a filter, and an agitator. The agitator has agitator blades extending outwardly from the lower end. The agitator end is positioned in the concentrator chamber and supported for rotation about its central axis and for reciprocal movement along its central axis. The concentrator has a top with an upper opening through which the upper end of the actuator stem extends, and a lower opening in which the filter is positioned. The concentrator chamber can have a cylindrical inner wall, and the agitator blades can have an outer edge in close proximity to the inner wall with the space between the outer edge and the inner wall being less than the diameter of the gel beads. The filter is selected to block effective flow of plasma therethrough under ambient gravity conditions and permit plasma and plasma concentrate flow therethrough under centrifugal forces of the separation gravity.

  • Publication number: 20090049741
    Abstract: According to the invention, unpurified biodiesel is brought in contact with cellulose-containing material by continuously and/or discontinuously mixing the same in order to eliminate the glycerin and catalyst residues, such as potassium soaps, accumulated during the production of the biodiesel. A system for carrying out said method comprises an agitated sedimentation tank (1) with a conduit (4,5) for delivering purified biodiesel into the agitated sedimentation tank (1) and a conveying device (6) for feeding cellulose-containing material into the agitated sedimentation tank (1). A drive unit (51) for an agitator (50) is disposed in the agitated sedimentation tank (1). A conduit (16, 20) extends from the agitated sedimentation tank (1) to at least one static sedimentation tank (2, 3). A valve (13) via which solid matter can be discharged from the agitated sedimentation tank (1) is mounted in the area of the bottom of the agitated sedimentation tank (1).

  • Publication number: 20070187336
    Abstract: A reservoir management system for a water reservoir having inlet and outlet piping and means for adding chemicals in controlled amounts to the water within the reservoir. One or more eductors are positioned within the water reservoir to mix and circulate water within the reservoir. A recirculating pump is located externally to the reservoir and has an inlet line that taps into the outlet piping from the reservoir. One or more sample lines remove test streams of water from the reservoir which are analyzed to determine the level of at least one of chemical in the test stream to provide a chemical-related signal. A controller receives the signal and compares the signal to a set point indicative of the level of chemical desired within the reservoir to maintain, increase, or decrease the amount of chemical added to the water within the reservoir in controlled amounts.
