  • Method for removing sulfur and nitrogen compounds from a gas mixture
    Patent number: 4167578
    Abstract: The Air Quality Control System utilizes the reaction between nitrogen oxides and the sulfites and bisulfites which are produced as a slurry of lime/limestone absorbs sulfur dioxide from a mixture of gases to produce ammonia from the absorption of nitrogen oxides.

  • Vapor generator and MHD power plant
    Patent number: 4163910
    Abstract: A magnetohydrodynamic generator discharges its gases to a vapor generator. A portion of the heat discharged to the vapor generator is recovered to elevate the temperature of the combustion air to the MHD burner. The burner discharge of an atmospheric heater further raises the temperature of the combustion air. The MHD exhaust gases passed through the vapor generator and the gases discharged from the atmospheric heater are combined to superheat the generated vapor and feed liquid to the vapor generator.

  • Apparatus for application of electrostatic fields to mixing and separating fluids
    Patent number: 4161439
    Abstract: Flow paths for liquids are disclosed in vessels, the paths oriented with electrodes which are electrically energized to establish electrostatic fields through the paths. One of the liquids is more polar than the other liquids in the paths. One of the fields is intense enough to generate the force to move drops of the polar liquid fast enough to shear the drops to smaller sizes and disperse the smaller drops. A second one of the fields is intense enough to generate the force to move the dispersed drops into coalescense. Various spacing and means of energizing the electrodes are disclosed to place the forces on the liquids in sequence and at different intensities.

  • Fluid pressure relay and output booster
    Patent number: 4151856
    Abstract: A primary element is connected to a control element of a first fluid pressure relay to move the element to positions at which pressure fluid outputs of relatively small volumes will be generated to represent the element positions. The pressure fluid outputs of the first relay are directed to the input of a second relay which generates pressure values for pressure fluid which are proportional to the first relay outputs in, and at, relatively larger volumes of the pressure fluid.

  • Method and apparatus for separation of fluids with an electric field
    Patent number: 4126537
    Abstract: Fluids are separated by passing their mixture through an electric field which is varied in strength. As coalescense of a first fluid dispersed in the second fluid begins, the mixture is flowed in a path which carries the coalescing fluid through the field which progressively changes strength. Fluid shear forces are avoided between the coalescing fluid and the fluid in which the coalescing fluid is dispersed. The size of the coalescing fluid drops increase and separate from the remaining fluid mixture under the force of gravity.

  • Process for mixing and separation in a solvent extraction system
    Patent number: 4120769
    Abstract: An ion exchange compound in a fluid organic carrier is cycled between mixing and separating from a weak acid stream and a strong acid stream. The weak acid stream is cycled between directly contacting ore to chemically dissolve metal and exchanging the metal for hydrogen ions of the exchange compound. The strong acid stream is cycled between exchanging its hydrogen ions for the metal bonded to the exchange compound and yielding the metal to a recovery system. The mixing and separation of the organic carrier with the two acid streams is by a pump, an electric field and a centrifuge.

  • Convection baffles
    Patent number: 4117806
    Abstract: A heat source and an element to be heated are immersed in a common liquid heat exchange medium. Baffles are arranged to guide the heated portion of the liquid upward and toward the heated element and guide the cooled portion of the liquid downward and toward the heat source in such a manner as to avoid conflict between the two flows to maximize the heat exchange between the source and element.

  • Method and apparatus for separation of fluids with an electric field and centrifuge
    Patent number: 4116790
    Abstract: Fluids are separated from each other by passing their mixture through an electric field and centrifuge in sequence. The drops of a first fluid dispersed in a second fluid are coalesced by the force of an electric field to a predetermined size. The mixture is then passed into a centrifuge which develops the force to move the coalesced drops away from the other fluids of the mixture without reaching the value at which fluid shear forces, between the coalesced fluid and the fluid in which the coalesced fluid is dispersed, will fragment the coalesced drops.

  • Turbine meter for bi-directional measurement of fluid flow
    Patent number: 4109526
    Abstract: A multi-bladed turbine meter is in a fluid flow line and has two magnetic pick-ups at the periphery of its blade tips positioned to be pulsed at different times by each blade as each blade passes the pick-ups. A circuit is connected to both pick-ups to determine which pick-up is pulsed first and to register the volume of fluid which is passed through the meter in each direction.

  • Centrifugal gas scrubber
    Patent number: 4102657
    Abstract: Air quality control system scrubs flue gas of SO.sub.2 and particulates with a slurry of lime/limestone and water. The contact between the slurry is in a centrifugal section which is the upper part of a tank in which the chemical action is completed and from which the slurry is recirculated to the contact section. The gas to be scrubbed is inserted into a circular path within the scrubbing section into which the slurry is sprayed. The treated gas is withdrawn from the circular path in heat exchange relationship with the incoming gas.
