Title: Aqueous alkaline composition
Inventor: LENOIR PIERRE MARIE
IPC: C11D1/86
Filed: 1994-11-04
Abstract: The aqueous composition comprises a non-ionic surfactant and an alkali metal hydroxide.        The non-ionic surfactant is a propylene oxide-ethylene oxide derivative of an alcohol of Formula I        R-O-[C2H3(CH3)O]a-[C2H4O]b-H              (I) and/or a butylene oxide-ethylene oxide derivative of an alcohol (ROH), of Formula II        R-O-[C2H3(C2H5)o]c-(C2H4O]b-H             (II) wherein R is a linear or branched-alkyl or alkenyl group containing from 4 to 11 carbon atoms, (a) (the average degree of propoxylation per mole) is from 2.5 to 7, (b) (the average degree of ethoxylation per mole) is from 1 to 10, and (c) (the average degree of butoxylation per mole) is from 0.5 to 4.      The content of the alkali metal hydroxide is at least 5 percent, based on the total weight of the aqueous composition.

Patent CA-2135437-A1 (CA)
Inventor: SEWELL FREDERIC D
IPC: F24F8/142
Filed: 1994-11-09
Abstract: An  automatically controlled water  spray  air purification system  is  incorporated  in  a  heating,  ventilating  and  air conditioning unit serving a conditioned interior building space.          The purification system is operative to receive a portion of the return air that would normally be flowed through the unit, mix the received return air with a quantity of outside ventilation air, purify the return air/outside air mixture using water sprayed from a sump portion of the purification system, and flow the purified air into the unit for mixture therein with the balance of the return air being flowed therethrough to the conditioned space.          Damper structures on the unit and its associated air purification system permit selective variance of the percentage of the unit discharge air that has traversed the purification system.   The water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back  into the  sump after cleansing air traversing the purification system.  Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water.   A dehumidification structure incorporated in the purification system is automatically controlled to remove moisture from purified air exiting the purification system.
