Abstract: Herewith are methods and embodiment of an apparatus for using geothermal heat for pyrolysis. In some embodiments, a pyrolysis reaction chamber is lowered into a well, where the pyrolysis reaction can be driven by geothermal heat. In some embodiments the reaction chamber is connected to second chamber to contain the gas reaction products produced by the pyrolysis reaction. In some embodiments, the reaction chamber and the gas collection chamber are separated by some distance in the well, and are connected by a long hose or conduit. A spallation drilling apparatus is also disclosed that uses jets of hot fluid for drilling. This is compatible with drilling wells in high temperature zones, such as a lava dome. A simplified pyrolysis reactor for use in a lava dome is also disclosed, in which the dome functions to contain the reaction, and the apparatus to facilitate pyrolysis is far more compact.

Abstract: A beach cleaner that is simple in configuration and light in weight and can be manufactured at a low cost. The beach cleaner is easy with regard to maintenance and inspection and can efficiently reclaim various kinds of refuse scattered on a beach. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The beach cleaner is towed along a surface F of sandy soil by a traction vehicle R. A bar-like scraper is provided at a lower portion of a front portion of the traveling body and extends in a widthwise direction of the traveling body through a scraper supporting member for scraping up refuse on the sandy soil while the traveling body is operating. A refuse reclamation section is provided on the traveling body rearwardly of the bar-like scraper for collecting pieces of refuse scraped up and thrown rearwardly by the bar-like scraper onto a net member.

Abstract: The invention is a generally V-shaped, rearwardly slanted plow blade having earwardly tapering raking teeth disposed in a downwardly widening opening at a lower central portion of the blade.

Abstract: An apparatus is described herein for gathering vegetables such as potatoes and other root vegetables from a plurality of rows into a central region for subsequent harvesting. The apparatus includes a support frame structure adapted to be secured to a tractor. A pair of wings are secured to the frame and they are adapted to extend, when in use, laterally outwardly relative to the forward direction of travel of the tractor. Each of these wings includes an endless flexible tine carrier mounted thereon for travel in an endless path, such path of travel including an upper run and a lower run. A plurality of tines are secured to and project outwardly in spaced relationship to each other from the flexible tine carrier for movement along the above-noted path of travel. Thus, during use, the tines located along the lower run of the path of travel are capable of engaging the vegetables lying on or in the earth.

Abstract: An apparatus adapted to dig four rows of growing peanut-laden plants and dispose them in turned position as two windrows, the apparatus having two sets of plows with the forward push of the leading end of the plows being away from the center of the front of the apparatus, and two elevating conveyors, one behind each set of plows, for removing as ribbons of peanut plants the four rows of plants, two ribbons of plants being elevated by each conveyor and dropped from the height of the conveyor to an inverting means to place the rows of plants from each conveyor in a windrow on the ground in a turned position.

Abstract: Vehicle adapted for being towed along undersea floor area where desired mineral aggregates, such as manganese nodules, are dispersed on ocean bottom carries horizontally fenestrated sweeps and hydraulic transition chamber utilizing towed motion and hydraulic suction for acquiring, concentrating and transmitting desired aggregates to conduit for upward transport.
