Abstract: A landfill gas vent flare is provided which includes a flarehead disposed in communication with a landfill gas vent wherein landfill gas is permitted to flow therethrough. A spark plug is located on the flarehead and is electrically connected to a solar powered ignitor which provides electrical impulses to the spark plug at regular predetermined intervals to generate a spark every 1.5 seconds to ignite the landfill gas and ensure the landfill gas burns continuously. The sparks are continuously generated regardless of the presence of landfill gas or flame in the flarehead. The flarehead comprises an inverted, modified frusto-conical structure and includes a plurality of inlets which permit air to enter the flarehead and mix with the landfill gas to facilitate combustion and to further ensure continuous burning of the gas.

Abstract: Gas and/or liquid exchange between a first area within a bulk material pile and a second area outside the bulk material pile is enabled by creating a substantially horizontal cavity during the formation of the bulk material pile, and establishing a conduit between the cavity and the area outside the bulk material pile during the formation of the bulk material pile. Where the bulk material pile is a solid waste pile, the cavity may be created using a substantially horizontal, elongated leaching chamber, and the conduit may be created with a system of pipes.

Abstract: A method and apparatus for automatically shutting off a dispensing device when the fluid source tank is empty includes a programmed pump controller in communication with the dispensing device and a flowmeter having a pulse generator. Upon startup of the dispensing device, the controller waits for an initial time period, then periodically determines the pulse frequency which correlates to a rate of fluid flow. The pulse frequency is compared to a calculated average pulse frequency and, if the pulse frequency has changed a pre-selected, pre-determined amount or percentage when compared to the average pulse frequency the dispensing device is shut-off. The change in pulse frequency indicates ingestion of air into the pumping system meaning an empty source tank.

Abstract: A synthetic cover for bulk material piles and loads in transit may be formed from a mixture of liquid, binder, and fibers. These constituents may be mixed and applied to cover a waste pile. The cover will harden to minimize water infiltration, wind blown dust, odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include portland cement, portland cement with flyash, cement kiln dust with or without bentonite, or stone dust. The fibers may comprise shredded paper or wood or plastic fibers.

Abstract: The in situ process for increasing the capacity of a municipal solid waste landfill involves disturbing the municipal solid waste present within a landfill site, adjusting the moisture content of the waste material, adding a lime reagent, stockpiling the waste material and allowing the temperature to increase so that aerobic biostabilization is facilitated and allowing the temperature of the municipal solid waste material to decrease to a stable point. The process can be practiced with the use of currently available types of earth moving and refuse handling equipment and involves the addition of no other substances to the municipal solid waste except lime and water.

Abstract: A synthetic cover for waste piles may be formed from a mixture of liquid, binder, cellulose fibers and plastic fibers. These constituents may be mixed and applied to cover a waste pile. The cover will harden to minimize odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include cement kiln dust with or without bentonite, or portland cement with flyash or stone dust. The cellulose fibers may comprise shredded paper or wood.

Abstract: A high efficiency waste placement and disposal method for disposing of solid waste in a landfill includes size reducing the solid waste, moisture adjusting the solid waste, placing the solid waste in a preselected geometric form thereby forming a waste pile, coating the exposed portion of the waste pile with a synthetic covering compound comprising a liquid, binder, cellulose fibers, and plastic fibers, biostabilizing the waste pile and compacting the waste pile. The waste is preferably placed in a matshaped stockpile for efficient biostabilization through sufficient aeration and moisture adjustment and compaction.

Abstract: A hydraulic radial piston power transmitting assembly including a hoursing and a back plate with a fixed pintle attached to the back plate which rotatably supports a cylinder block with radially spaced bores and pistons therearound, a drive shaft which drives the cylinder block through a coupling means, a cam ring surrounding the cylinder block which is pivotally connected to the housing allowing limited movement of the ring to vary the piston stroke in the cylinder block and cam ring positioning means including a rotating control arm mounted in the housing, swivel means attached to the cam ring with a spherical surface thereon and a sleeve means slidably received on the control arm means including a lateral bore for sliding receipt of the spherical surface of the swivel means to accommodate the locus of points which define the cam ring's various displacement positions.

Abstract: A pozzolanic mixture for stabilizing landfill leachate which includes fly ash with an excess of lime, kiln dust, and optionally bottom ash, which is combined with the landfill leachate with a makeup quantity of water to produce a stable cementitious pozzolanic mixture that hardens to a mortar-like material. The hardened material exhibits favorable handling characteristics, and resists leaching of its environmentally hazardous components.

Abstract: An integral sensor for an hydraulic motor measures speed, torque and rotation displacement produced by the motor by combining pressures produced in pressure chambers of the hydraulic motor as the rotor rotates enabling a pressure sensor to provide a pressure signal defined by at least three states which permits incremental movement of the rotor to be determined. Zero positioning determined by coupling pressure through the rotor to create a unique occurrence reflected in the pressure signal once per revolution.
