  • Patent number: 6591614
    Abstract: In heating and cooling apparatus, molecules of working gas are excited by light irradiation and thereby cooled as the gas flows through a mirrored cooling cell. In a closed loop embodiment, the gas then flows by means of a fan or compressor to a first heat exchanger where heat from the matter being cooled is transferred to the gas; and, then to a second heat exchanger where heat is transferred from the gas to a heat sink. The apparatus may be used either like a heat pump or air conditioner. In an open-end cooling apparatus embodiment, the gas flows from the cooling cell, through the first heat exchanger, and to atmosphere. The light source may be a 10.6 micron laser; or a 9-11 micron electric arc, a hot filament or the Sun. Working gases comprise N2 and C02; exhaust gases of engines or fuel cells; and gases which comprise different molecular composition gases or different isotopic species of the same molecular composition gas.

  • Patent number: 6485647
    Abstract: The functioning of the leach field of a septic tank type sewage system is maintained or rejuvenated by flowing air or other active gas through the system's conduits, for instance, leaching chambers or perforated pipes in stone filled trenches. Differential pressure created by an air mover forces air or other active gas to flow through the soil adjacent the conduits, to an extent sufficient to push water from any saturated soil and effect desirable aerobic biochemical conditions in the soil. In alternate embodiments, conduits may be pressurized or evacuated. Valves and other plumbing are provided to control air flow and enable continued function of the sewage system during air flow treatment. Auxiliary piping, buried adjacent the trenches of the leach field, is pressurized or evacuated to cause air flow through the soil and or the conduits of the leach field.

  • Patent number: 6129290
    Abstract: A snowmaker is comprised of a head which has an outer ring of nozzles which form a flow of primary water into droplets which move downstream preferably along paths running at a slight radially outward angle, together with a central nucleator which discharges frozen nuclei particles outwardly from a plurality of atomizers at the downstream end cap end of the nucleator. The nucleator is readily disconnectable from the ring. Secondary water flow is fed to the nucleator so it swirls at high velocity within, to greatly enhance the warming effect of the water on the nucleator parts, and to thereby inhibit accumulation of exterior ice. The secondary water is mixed with compressed air as they both enter the atomizers of the end cap. A resultant flow of nuclei from the atomizers is discharged so the flow merges with the plume of primary water droplets from the nozzle. Preferably, flat spray nozzles are used.

  • Patent number: 6018909
    Abstract: Soil profiles of sports fields, such as those in stadiums and golf courses, are treated by injecting or suctioning gases and water by means of buried horizontal pipe arrays or by vertical penetrators. The extent of soil treatment is controlled by measurement of subsurface gas composition and pressure at locations remote from the point of gas injection or removal, preferably by using a special probe. Penetrators and probes form seals within shaped holes in the soil profile, to control the depth of the layer at which gas is exchanged, and to inhibit atmospheric air flow vertically along the bodies of the devices. For example, a conical penetrator section forms a seal within the hole by compacting the shoulder of a stepped hole and it forms a second seal at the surface of the soil by means of a plate and gasket. In other penetrator installations, a radially expansible material forms the seal. Penetrators of one or two part construction may be removably installed in fields, to facilitate re-treatment.

  • Patent number: 5971389
    Abstract: A singulator adapted for feeding articles of varying thickness is comprised of a driver with a movable and resiliently biased retarder, called a dancer. The dancer moves back and forth along the article flow path, in response to the passage through the nip of the articles being singulated, to automatically set the gap at the singulator nip. A dancer body motion may be linear or pivoting. The path of article travel through the singulator nip is at an angle to the downstream article flow path. Thus, when a takeaway device pulls on the article, the dancer moves to open the singulator gap slightly to enable the article to more freely be taken away. A preferred dancer has an endless belt and is spring biased to lightly contact the driver at the nip in the absence of an article; and, periodic reversal of driver direction engages the dancer belt surface at the nip and moves it upstream, thereby exposing a new surface.

  • Patent number: 5890838
    Abstract: In a system for dispersing stormwaters beneath the earth surface, a pair of arch shaped corrugated molded plastic chambers lie parallel each to the other upon a bed of gravel and are covered with soil. A bridge cover spans the space between the sidewalls of the adjacent chambers, to keep soil above from entering. Abutting base flanges establish the chamber spacing which fits the bridge cover and also protect the gravel at the bottom of the space from erosion. Stormwater is delivered to the space, to then flow through sidewall perforations into the chambers' interiors where it is stored and gradually dispersed into the earth. Debris settles in the pocket at the bottom of the space and is removed by a perforated pipe lying in the space. Chambers have high aspect ratios, of 0.8 to 1 or more, and steep sidewall angles, of less than 15 degrees.
