Abstract: Apparatus including a building; and a system which includes a water line comprising a water supply line substantially permanently installed and plumbed inside the building for supplying water at a pressure in a first pressure range; a pump substantially permanently installed and plumbed inside the building, wherein the pump has an inlet operably attached to the water line and an outlet for delivering water at a pressure higher than the pressure in the first pressure range through a fluid line at a higher pressure than the pressure in the first pressure range, wherein the fluid conduit is substantially permanently installed and plumbed inside the building and is operably attached at one end to the pump outlet and operably connected to at least one system outlet; a connector for selectively, operatively connecting or disconnecting a spray wand to at least one system outlet; a cleaning chemical supplier for operably introducing a cleaning chemical into fluid passing through the fluid conduit; and a wireless remo

Abstract: A cleaning system which is centrally and permanently installed in homes or commercial buildings and is connected to the water line therein. The system includes a pump operably attached to the water line and one or more freeze-proof valves are connected to the outside wall of the building or to an adjoining building. A fluid conduit is operably attached to the pump outlet and at the other end to the inlet of the freeze-proof valve. A spray wand, including an outlet nozzle, is attached to the freeze-proof valve on the outside of the building or buildings and includes structure for easily connecting or disconnecting such spray wand so that it can be removed when not in use and used at any one of the freeze-proof valve outlets. One or more chemical solutions can be selectively introduced into the fluid passing through the high pressure line.

Abstract: There is disclosed a treatment of exhaust gases containing detectable quantities of multivalent heavy metals in high oxidation states by introducing a sulfur reductant into contact with the exhaust gases and maintaining the contact of the sulfur reductant with the exhaust gases under appropriate conditions to favor the reduction of the heavy metal to an harmless, lower oxidation state. Sulfur dioxide is preferred for this treatment. After the treatment with the sulfur reductant, the exhaust gases are treated to remove the excess or residual amounts of the sulfur reductant and the compounds of higher oxidiation states of the sulfur which have been formed by the reduction of the heavy metal. When sulfur dioxide is used, the exhaust gases can be passed into contact with an aqueous alkaline solution which absorbs oxides of sulfur, such as sulfur dioxide and trioxide from the exhaust gases.

Abstract: A testing arrangement in which an AI system is interfaced directly to an automatic test system (ATS) such that from the point of view of the ATS, the actions of the AI system are indistinguishable from the actions of an intelligent human operator. A testing apparatus comprises an automatic test system, communication means, and an AI system. The automatic test system comprises an automatic test equipment (ATE) controller, at least one test instrument connectable to the ATE controller and to the unit under test (UUT), and storage means for storing a functional test procedure (FTP) for the UUT. The ATE controller includes an I/O port and ATE data processing means for executing the FTP in response to a start FTP command, and for providing an FTP data set at the I/O port. The FTP data set comprises data indicating the results obtained by executing the FTP. The communication means is connected to the I/O port.

Abstract: A demountable wheeled liquid sprayer comprised of an elongated handle having an angulated forward end portion supporting a battery driven electric motor with a depending drive shaft rotatably mounting a cup having inwardly and upwardly extending sidewalls with circumferentially spaced openings extending downwardly and outwardly therethrough around the periphery of its bottom. The handle is detachably mounted on a small two-wheeled frame and supports a removable and disposable liquid container which discharges its contents into the cup through conduit means and an associated valve. Valve control means is mounted on the handle and simultaneously opens the valve while activating the motor, or closes the valve while deactivating the motor. The handle and described sprayer may be detached, transported and used manually absent the wheeled frame.

Abstract: A method is disclosed for processing industrial waste waters and, in particular, blow down water from thermal electric plants. The water is processed to concentrate the salts contained therein and to obtain a concentrated brine which can then be passed to a thermal evaporator and/or solar evaporation ponds. The water is processed by the addition of magnesium hydroxide and carbon dioxide in amounts sufficient to precipitate the calcium as calcium carbonate, thereby obtaining a water reduced in calcium content and increased in magnesium content from the industrial waste water. The treated water is processed to recover a purified water from a brine, preferably by reverse osmosis. Calcium hydroxide is added to the brine generated by the reverse osmosis process in an amount sufficient to precipitate magnesium hydroxide therefrom which can be recycled to supply the magnesium hydroxide used in pre-treatment of the water prior to the reverse osmosis process.

Abstract: There is disclosed a process for biological denitrification of nitrate containing waters, particularly agricultural drain waters, sewage effluents, ground waters and the like by contacting the water with a solid cellulosic substrate comprised chiefly of paper or paper pulp in the presence of anaerobic bacteria in an active growth phase to reduce the nitrate content of the water by biological oxidation of the substrate.

Abstract: There is disclosed a treatment of water that greatly reduces the scaling tendency of the water during its subsequent use or processing. The treatment comprises precipitation and separation of the calcium values of the water as calcium carbonate by the addition of magnesium hydroxide precipitant thereto, with, as needed, a carbonate source, e.g., carbon dioxide. During subsequent use or processing, salts dissolved in the water are concentrated in a residual portion thereof and the residual portion is processed by the addition of calcium hydroxide to precipitate the dissolved magnesium values from the residual portion and supply the magnesium hydroxide that is employed as the precipitant in the treatment of the raw water. The treatment can be applied to any of a variety of water treating processes such as reverse osmosis, distillation, electrodialysis, freezing, vapor compression, ion exchange, evaporative cooling and/or boiler feed water treatment.

Abstract: A process for the repair or reinforcement of fabrics woven of smooth surface synthetic fibers, such as nylon. A swatch of like material having one side coated with a heat sensitive adhesive is used. The area to be repaired or reinforced is buffed with fine grit abrasive to artificially raise a nap on the threads. The area to be repaired may then be preheated. The patch is placed in face-to-face contact with the buffed area and pressure and heat are applied to effect a weatherproof bond between the fabric surfaces.

Abstract: An improved process for making acrylamide from a composition of acrylonitrile and water utilizing an improved Raney copper catalyst. The catalyst is prepared by contacting particulate copper/aluminum alloy particles with an aqueous solution containing aliphatic hydrocarbon compound having at least two carbon atoms per molecule and further having at least two oxygen containing groups per molecule.
