Abstract: A process and apparatus for separating components of a source gas is provided in which more soluble components of the source gas are dissolved in an aqueous solvent at high pressure. The system can utilize hydrostatic pressure to increase solubility of the components of the source gas. The apparatus includes gas recycle throughout multiple mass transfer stages to improve mass transfer of the targeted components from the liquid to gas phase. Separated components can be recovered for use in a value added application or can be processed for long-term storage, for instance in an underwater reservoir.

Abstract: The air purification system and method for purifying and cooling air for use in a building has an air pollutant removal stage, an air pre-cooling unit, and a dual cooling and water removal unit, including a cyclone separator having a cooling coil wrapped around the separator for condensing and removing water from the airflow. The method comprises the steps of removing pollutants from an incoming polluted airflow to provide a substantially pollutant free outgoing moist airflow; pre-cooling the substantially pollutant free moist airflow to provide a clean cool moist airflow; and condensing water out of the clean cool moist airflow to provide a substantially clean dry airflow suitable for use in a building.

Abstract: An assembly for purifying water includes a high intensity ultraviolet light or corona discharge ozone generator 4 and output line 15 for introducing ozone into a tube 20 carrying water to be treated. Downstream of the ozone injection point 22 is an ozone contact time segment 24 that terminates at an input port of a bubble separator column 26. The column includes a water level hysteresis inducing means that is adapted to cause water within the column to continuously alternately fill and purge between an upper and a lower water level in order to enhance ozone concentration. The hysteresis inducing means may include a water level sensitive electrically actuated valve 38.

Abstract: A versatile waste disposal apparatus for separating and disposing the liquid waste from vacuum cleaning of soiled carpets. The air, liquid and accumulated dirt in a mixture from a conventional vacuum cleaner are separated in one large tank, and the filtered liquid is passed on either to an integrated or non-integrated smaller tank with cutoff, air venting, and pump controls. The filtered liquid is ultimately passed on to a wastewater system so that the tanks are empty after use. The waste disposal apparatus can be integrated with a dwelling's central vacuuming system and operated on house current. The apparatus can be installed in a vehicle and powered by the vehicle's battery.

Abstract: An induction type of vacuum assembly for use with wet and dry vacuums is described. It includes a motor chamber; a solution chamber and a lower chamber for use inside of a canister that holds water and/or cleaning solution. A central chamber is inside of a solution tank and is in fluid connection with the lower chamber through a cage so as to prevent ingress of water into the motor assembly in the even that the level of the water rises. Foam filter(s) are used in connection with the cylindrical chamber so as to collect dirt and dirty water throughout the vacuuming operation.

Abstract: An air cleaner for efficiently providing clean air for a structure is comprised of a housing having an intake port and an exhaust port. At least one air chamber having a liquid reservoir at its base is disposed within the housing. A fan draws air through the intake port and the air passes in turn through each liquid reservoir and then its air chamber and discharges the air through the exhaust port. A switch controls the fan and is turned off whenever the liquid level within the device is improper with the device having a flush valve for discharging exhaust liquid and a liquid fill valve for introduction of liquid.
