  • Patent number: 9550311
    Abstract: A system and method for monitoring and adjusting a constant flow asphalt manufacturing process includes monitoring the ratios of recycled material to virgin material to minimize costs and adjusting the mixture in real time. Pulverized asphalt shingle (PAS) material may be used as a source of recycled asphalt oil and fed to a mixing drum with real-time monitoring while making real-time adjustments to supplement the asphalt with new asphalt oil to the mixer. The systems and methods may also be used for monitoring, metering, and supplementing recycled aggregate from recycled asphalt pavement (RAP) with new aggregate. The systems and methods may use one or more processors or programmable logic controllers (PLC) to meter the addition of new materials.

  • Publication number: 20140290131
    Abstract: Apparatus for heating the soil or other growth media in a plant propagation container, including a set of low-voltage silicone-encased heating elements embedded directly in the growth media. The silicone heating elements are sturdy and inherently waterproof, as they are designed to operate in harsh, high moisture industrial environments, and placing them in the growth media itself dramatically improves the heating efficiency and effectiveness. And being low voltage devices, typically 12 VDC, the risk of electrical shock to workers is substantially eliminated, even should the electrical cords become damaged by abrasion or misuse. Preferably, the apparatus includes a set of heating elements, a DC power supply for developing the DC operating voltage for the heating elements, and a thermostat for regulating the amount of heat produced by the heating elements.

  • Patent number: 8631944
    Abstract: A method and apparatus (1) for processing soil infested with plant root material. The method comprises depositing the soil on a vibrating conveyor support (105) at a substantially constant depth, wherein the vibrating conveyor support (105) is arranged to enable the plant root material to be hand-picked. In this way, soil throughput may be maximised without compromising removal of the plant root material. Further, fragmentation of the plant root material may be minimised. The soil may be screened using a vibrating screening mesh (107) to remove smaller particles prior to it being deposited on the conveyor. The soil may be heated, and the processed soil passed under an infrared detector (119) for detecting the presence of plant root material, to thereby objectively control quality.

  • Patent number: 8573144
    Abstract: An exhaust conditioning system for use with a tractor towing an air seeding implement comprises an exhaust duct arranged to communicate exhaust emissions from the engine of the tractor to the seed fan of the air seeding implement. A condenser receives the exhaust emissions of the exhaust duct therethrough between the engine and the seed fan. A condenser fan cools a surface of the condenser. A computer controller controllably varies a rate of at least one of the condenser fan, the seed fan or revolutions per minute of the engine responsive to a sensed temperature of the exhaust emissions to maintain the temperature of the exhaust emissions within a selected temperature range and such that the exhaust emissions are arranged to influence germination of the seeds either by humidity, oxidised organic matter or bio-char.

  • Publication number: 20130255144
    Abstract: The present disclosure provides a method and apparatus for sterilization of soil in the field by pressure comprising grinding up soil using a rototilling mechanism, creating a pulverized soil; conveying the pulverized soil to a two-part holding container; and, transferring the pulverized soil from a lower section of the two-part holder container to a middle container which is operably linked to a pressurization mechanism, thereby allowing for the pulverized soil to be treated and sterilized with high pressure in the middle container resulting in a treated soil. The treated soil is then transferred to a transfer container being configured to shape a growing bed to a desired configuration using the treated soil which is deposited there.

  • Patent number: 7833476
    Abstract: A flamer may be used to sterilize poultry litter, soil, concrete, etc. The stationary or mobile flamer disclosed comprises a hood to contain the heat, an external frame, and burners. A fuel tank may be carried on the flamer or on a tractor. An additional embodiment provides for mounting the flamer on wheels, permitting the unit to be towed by a truck, four-wheeler, tractor, etc. The burners are adjustable as to angle, and fueling rate. A pressure in the fuel system is controlled by selectively switching between the liquid and vaporous components of the fuel. By limiting how low the pressure may fall, the flow of fuel from the tank to the torches is more consistent.

  • Patent number: 7789027
    Abstract: A soil treatment device that reconditions topsoil by removing an amount of topsoil, treating the topsoil, placing bacteria and small organisms within the topsoil, and then returning the topsoil to the ground surface. The device removes the topsoil from a ground surface by a front-mounted set of cutter blades that remove topsoil down to a specific depth and places it on a conveyer belt. The belt then transports the topsoil into the device, where it is irradiated; seeded with bacteria, microorganisms, and seedlings; and then discharged back onto the ground surface.

  • Patent number: 7469500
    Abstract: A system and method for nematode extermination in lawns using an array of insulated heat blankets (2) placed on the lawn, and energized in a controlled sequence to raise the soil temperature to an effective degree and depth to exterminate nematodes. An electric current controller such as a programmable logic controller (PLC) activates a first subset of the blankets (2) until they reach an upper setpoint temperature, then maintains the blanket temperature within a desired range with reduced current while activating additional blankets. The heat penetrates the soil over a period of about 20 to 50 hours to raise the temperature to at least about 52° C. (125° F.) at a sufficient depth such as at least 12 cm (4.7 inches) to kill at least most nematodes.
