  • Patent number: 5548907
    Abstract: Several methods and apparatus for transferring heat, mass and momentum between a fluid and a surface are disclosed wherein the fluid is separated into a multiplicity of tiny jets that impinge upon a surface to be treated and flow across it for very short distances before reforming jets that leave the surface. While in contact with the surface, the fluid flow is laminar and the boundary layer that resists transfer of heat, mass and momentum is extremely thin. Hence, heat, mass and momentum transfer coefficients are large and predictable from first principles of physics. The pressure drop and fan power required to form these jets are generally less than that required to drive the flow parallel to the surface for long distances, where the boundary layer grows much thicker.

  • Patent number: 5456596
    Abstract: A multivortex device is provided comprising a series of adjacent plates with specially designed grooves and perforations which, when mounted transversely of a uniform fluid flow in a duct, results in the formation of numerous small adjacent flow vortices either all rotating in the same direction (co-vortices) or adjacent vortices rotating in opposite direction (countervortices). The fluid at the peripheries of adjacent co-vortices move in opposite directions and friction converts their rotational kinetic energy into turbulence within a few vortex diameters downstream from the multivortex device. The fluid at the peripheries of adjacent counter-rotating vortices move in the same direction, such that they roll upon one another substantially without friction and persist for many vortex diameters downstream from the multivortex device. The adjacent plates of the multivortex device can be provided with additional grooves and passageways which allow a second and/or third fluid to be introduced within each vortex.

  • Patent number: 4874225
    Abstract: A solar greenhouse roof includes a plurality of relatively large sunlight reflectors which direct and receive sunlight to one or more relatively small focusing light reflectors. The light reflected from the focusing light reflectors is directed downward into the edges of plate glass pipe which are simply panes of plate glass mounted within the base of the roof. The glass pipes serve as a filter for blocking the transmission of ultraviolet and infrared light therethrough, thus allowing only visible light to reach such objects as plants located below the glass pipes. A protective Tedlar film or coated glass may be mounted atop the roof, the glass pipes may be aluminized on their planar surfaces to improve the internal reflectivity to visible light.

  • Patent number: 4742536
    Abstract: A communication system is connected to a pair of telephone conductors which supply telephone service to a telephone subscriber. An optically coupled switch connects a first winding of a transformer across the telephone conductors. A second winding of the transformer is connected to a modem for communicating over the telephone conductors via the transformer. A voltage sensor circuit senses the voltage across the telephone conductors and detects a reduction in the voltage level across the conductors which indicates an off-hook condition of a telephone unit of the subscriber connected to the conductors. The voltage sensor circuit also detects the presence of a ring signal on the conductors. The switch is periodically opened so as to disconnect the transformer from the telephone conductors, and permit the voltage sensor circuit to check for an off-hook condition.

  • Patent number: 4671805
    Abstract: Atmospheric occurrences that decrease visibility, particularly fog, smoke, smog and the like, are cleared at sites such as airports by an array of EGD spray units emitting submicron size charged water droplets to attach to airborne particulates and electrostatically precipitate those to ground. Independent variables of the array and the EGD jets from the spray units are controlled to control the dependent variables characterizing the space-charge cloud thus developed. The methods and apparatus control the height to which clearing of the airborne particulates occurs to improve visibility and the time required for such clearing. Specific compact spray units are self-contained, can be radio operated, and are movable. Placement of the units for removal of radiation and advection fog with respect to airport runways include a square array of the spray units proximate the runway for radiation fog control and upwind location of arrays for advection fog precipitation.

  • Patent number: 4587513
    Abstract: Apparatus and method for non-contact determination of shaft angle utilizes a patterned disc secured to the shaft or other rotor being observed. The disc has sectors of different optical properties whereby radiant energy directed to the disc will be encoded by the sectored pattern. A set of detectors, which each correspond to one of the sectors, provides variable output signals according to the amount of radiant energy attenuated by the disc and directed onto the detectors. These signals are converted to a set of digital signals which define a unique rotational position, and a computing means calculates angular position from these signals. The computing means will, if necessary, compare the digital output signals and then calculate angular position in a manner which is insensitive to small decenters (or lack of concentricity) in the arrangement of the shaft, disc, detectors, and any associated optical system.

  • Patent number: 4555909
    Abstract: A method and apparatus rapidly cools hot material of any shape without inducing distortion-causing temperature gradients between thick and thin sections. Water spray guns mounted on an enclosure surrounding the hot material launch drops of water towards the surface with sufficient speed to penetrate the vapor leaving the surface, but with insufficient flow rate to form a blanket of water thereon, to establish a turbulent mixture of water drops and vapor in equilibrium at the water boiling point temperature of 212.degree. F. Turbulent heat transfer to the vapor and evaporation of drops maintain the surfaces of the enclosure and the hot material at 212.degree. F. to cool the inner core of the hot material to 212.degree. F. by conducting heat to its surface. Irregularly shaped objects are cooled by setting each gun water spray rate to be proportional to the thickness of material where its jet strikes or by directing air at thinner locations to minimize temperature gradients within the material.

  • Patent number: 3991710
    Abstract: A coating system for efficient electrical precipitation of powder to articles. Articles are conveyed through a coating chamber where they are coated with a powder. Electrogasdynamic guns direct a cloud of charged particles into the coating chamber. Dilution air moves the cloud through the chamber with the articles. As the cloud moves with the articles, the charged particles precipitate to the articles. An exhaust section draws off the dilution air as the coated articles leave the chamber. Electrically conductive articles may be grounded through the conveyor system to provide a discharge path from the charged particles. For nonconducting or hard to ground articles, a precharge section places on the articles an initial charge of opposite polarity from the charged particles. A powder feed using a cylinder and piston arrangement to contain fluidized powder supplies a uniform powder suspension to the guns.
