Abstract: When a GPS unit electronically detects being within a boundary, a motor controller electronically controls providing electrical power from a battery pack to a high-speed electric motor directly driving a rotatable turbine rotor inside a cylindrical housing at operational speeds. The motor controller electronically controls the high-speed electric motor to stop rotation, to rotate at operational speeds, or to rotate at turbo boost speeds. A single remote electronically controls multiple motor controllers. The motor controller inverts DC battery voltage of 100 volts to 3-phase alternating current used by the high-speed electric motor. A DC-DC converter is electrically connected between the battery pack and a nozzle motor and a display.

Abstract: A debris blower includes an engine mounted to an engine mount and connected to a turbine. The engine mount and housing of the turbine are respectively mounted between a second side of a frame and first and second longitudinal supports connected to and between first and second sides of the frame. A screen guard is secured utilizing bolts extending in a non-rotatable manner from a top plate connected between the second longitudinal support and the second side. Due to the frame and engine mount having a parallelism and flatness tolerance, the engine and turbine can be aligned without shimming. A sensor senses first and second trip devices positioned at circumferential locations on the exit nozzle to rotate the exit nozzle to preset angles. Remote and hard wire controls each include direction and speed switches. A resume switch throttles the engine between idle and operating speeds.

Abstract: A top dresser advances sand contained in a hopper on a dispensing conveyor moving at a linear speed onto a rotatable spinner rotating at a rotating speed. The linear and rotatable speeds are controlled by a controller by electrically actuating first and second electrically actuated valves providing fluid flow to hydraulic motors driving the rotatable spinner and the dispensing conveyor. The rotatable and linear speeds are inputted into an electrical display electronically connected to the controller. The hydraulic flow to the second electrically actuated valve may be solely from the first electrically actuated valve to create back pressure acting as a cushion. Multiple function switches on the electrical display may be actuated in sequence to replicate a linear line relationship between the rotational and linear speeds. Start-up, run, look up and application calculation screens may be displayed on a monitor of the electrical display.

Abstract: The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on fracturing and/or rubblizing portions of said formations so as to enhance their fluid permeability, and wherein such methods further rely on chemically modifying the shale-bound kerogen so as to render it mobile. The present invention is also directed at systems for implementing at least some of the foregoing methods. Additionally, the present invention is also directed to methods of fracturing and/or rubblizing subsurface shale formations and to methods of chemically modifying kerogen in situ so as to render it mobile.

Abstract: A seeder (10) includes multiple cutting head units (30) pivotally mounted to a jack shaft (24) of a frame (12) and spring biased downwardly by hold downs (80). Each multiple cutting head unit (30) includes multiple roller blades (36) received on an axle (34) rotatably mounted in a carrier (32) and in gearing relation to the jack shaft (24). The roller blades (36) include a series of oppositely formed, circumferentially spaced radially extending indentations (36a) extending from a continuous, smooth periphery at a constant extent from the axle (34). Fingers (46) extending between the roller blades (36) are pivotally mounted to the carrier (32) to adjust the depth of the slits formed by the roller blades (36). Each hose (98) extending from a seed box (96) diverts seed into adjacent slits immediately after the roller blades (36).

Abstract: A broadcast spreading top dresser (10) includes a diverter (200) which can be positioned in an upper position for light applications and a lower position for heavy applications, with the diverter (200) extending through a slot (210) in an upper sheet (58) of the spinner assembly (40) and beyond and below the upper sheet (58) in the lower position. The leading edges (204) of the diverter (200) are spaced from the circular disks (154) of the spinners (54) intermediate the radial position that the material is dispensed unto the spinners (54) and the maximum rearward extent of the circular disks (154). The lower edges of the diverter (200) extend at differing distances into the thickness of the propelled top dressing material.

Abstract: The seeder apparatus includes a material hopper for dispensing material onto a conveyor to be moved thereby to an entry nip between a rotary brush and the conveyor for propelling the material downwardly at the discharge end. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor, with the metering gate controlling the rate of dispensation of seed or other material being moved to the entry nip. A shield assembly is provided to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by the brush and conveyor. In preferred forms, a separate seed hopper is mounted to the top dresser, and in a second embodiment, either seed from the seed hopper and/or dressing material from the top dresser hopper may be moved by the conveyor to the entry nip.
