Abstract: Process for producing fully desalted process water by the treatment of raw water with cation and anion exchangers in a separate multi-stage arrangement. The water which leaves the main cation exchanger stage or stages, has a residual sodium content of less than 0.5 mg Na/l before entering the anion exchange stage. Such water is fed through a strong acid cation exchanger stage, in which the exchanger material is present at a maximum of 50 percent as a suspended bed and the remainder as a solid bed. The exchanger material in the strong acid cation exchanger stage following the first strong acid cation exchanger stage, is present at a maximum of 25 percent as a suspended bed and the remainder as a solid bed.

Abstract: A power system comprises structures which capture wind and solar energy to drive turbines for generating power. The structures can assume different forms, some intended to operate only from wind power. All in common, however, have lower air intake means which can accept the wind from any direction, air passageways that conduct the air upward through turbines, and venturi-assisted upper air exhaust vents which discharge the air downwind. Structures intended to operate on solar power in addition to wind have generally transparent sun-facing outer surfaces to admit solar radiation into the air passageways, a heat absorbing and transferring means inside the air passageways, and sufficient height that the solar heated air will rise with adequate velocity to operate the turbines. The invention includes an air inlet louver configuration which permits free entry of normal winds, but restricts entry of winds that have excessive force.

Abstract: A moldable sound control composite is disclosed combining in itself when molded damping, barrier performance, and structural strength for use within a predetermined environment temperature range. As such, the moldable composite is not applied to other structures to damp their sound generation, but forms by itself a complete structural member having not only desirable sound reducing properties but desirable strength properties as well. The composite comprises a blend of a primary non-viscoelastic organic polymeric resinous material intended to impart structural strength to the composite, a secondary viscoelastic organic polymeric resinous material to provide damping performance, and filler material adapted to densify the composite and impart barrier performance. Optionally, at least one of the primary and secondary resinous materials may be thermosetting.

Abstract: A water mattress has a portion of its volume occupied by air or gas filled bodies which lower the total mattress weight and inhibit the under damped natural harmonic motion typical of conventional water mattresses. A method of fabricating the water mattress of the instant invention is also disclosed. The gas filled bodies comprise independent, elongate, parallel chambers having sidewalls which are secured to the bottom panel of the mattress. The chambers are positioned to float between the horizontal midplane of the mattress and its upper surface such that it exhibits the uniform force per area weight distribution characteristic found desirable in such devices. Air is supplied to the chambers through generally aligned access fittings on the chambers and water mattress.

Abstract: An apparatus for treating water in which water is delivered under pressure to a closed tank in the form of a spray or fog. An aerator in the bottom of the tank draws atmospheric air from outside of the tank and creates laterally directed air jets for violently stirring up and oxidizing the water. Gases are exhausted from the tank at the top. A series of baffles surround the aerator against which the jets impinge and provide for hydraulic streams. Float valves control the amount of water maintained within the tank. Treated water is drawn from the tank through a pipe extending to the lower portion.

Abstract: A method of combusting natural gas fuel in a two cycle, turbocharged internal combustion engine substantially reduces the production of nitrogen-oxygen emissions. An improved turbocharger design provides increased air charging pressure, produces a controlled lean air/fuel mixture and lowers peak combustion temperatures. A jet cell ignition device ensures uniform, reliable ignition of the lean air/fuel mixture under all operating conditions and the lean air/fuel mixture in turn encourages complete fuel combustion and provides excellent combustion characteristics with methane, ethane and heavier paraffinic hydrocarbon fuels. These structural modifications and adjustment of other operating parameters combine to reduce nitric oxide (NO) and nitrogen dioxide (NO.sub.2) emissions by as much as 75% while effecting only a negligible increase in fuel consumption.

Abstract: A method and apparatus for detecting the length of wire blanks in a wire cutting machine is disclosed, the machine including feed apparatus for feeding wire stock into the cutting machine, stop apparatus for engaging one end of the wire stock at a predetermined length in the cutting machine, and cutting apparatus for cutting wire blanks from the wire stock. When the leading end of the wire stock engages the stop apparatus with a predetermined pressure, the blank is at a proper length to be cut. The pressure causes the stop apparatus to expand radially. Strain gauges mounted about the stop apparatus detect the expansion by generating an electrical signal when connected in a bridge circuit. The strain gauges detect an over feed situation when the stop apparatus expands beyond a predetermined point. Similarly, an under feed situation is detected when little or no expansion of the stop apparatus is sensed.
