摘要： A propulsion system for a vehicle comprising a hydrostatic transmission wherein the system typically includes an electric motor, a hydrostatic pump preferably of the continuous variable displacement type, hydrostatic motors for cooperation with the wheel axles of the vehicle, and a gas accumulator which provides for the compression and expansion of a gaseous medium depending on whether the transmission fluid is being pumped into or withdrawn from the gas accumulator. The gas accumulator comprises a pressure vessel which serves as a structural member of the vehicle. It may have a tubular configuration disposed as a load-bearing structural member of the chassis or it may comprise a number of interconnected pressure-retaining panels, that form the vertical sides and/or roof sections of the vehicle. Suitable mechanical and electrical/electronic controls are provided to monitor the gas pressure in the gas accumulator and to regulate the stroke and function of the hydrostatic pumps and motors.

摘要： Gaseous fuels are produced by a process which involves simultaneous gasification of coal and pyrolysis of organic solid waste materials in a pollution-free conversion system. According to this process, a mixture of coal and organic solid waste materials is fed to the top of a reaction vessel such as a vertical shaft furnace or a blast furnace, wherein the feed is dried by heat exchange with the gases rising from the lower section of the reactor. Steam and an oxidant gas containing at least 75 volume percent oxygen are introduced to the bottom of the reactor for partially combusting coke and char in a partial combustion zone thereby providing the thermal driving force for the reactions in the reactor. The organic solid waste materials are pyrolyzed and the volatile components of the coal destructively distilled simultaneously in the presence of hydrogen in a pyrolysis and coking zone of the reactor wherein the organic solid waste materials are converted into char and the coal is converted into coke. The char and coke are reacted with oxygen and steam in the partial combustion zone. The descending inorganic materials are fused and the fused slag and molten metals are tapped from the bottom of the reactor. The gaseous products are removed from the top of the furnace and subjected to a product recovery section to remove the undesirable components. The ratio of hydrogen to carbon monoxide can be varied over a wide, commercially important range, by feeding secondary steam to a high temperature reaction zone intermediate the partial combustion zone and the pyrolysis and coking zone. Depending upon the ratio of hydrogen to carbon monoxide produced, the gaseous products can be used as fuel or as a synthesis gas for the production of methanol or methane.Gaseous product containing larger quantities of methane may be produced by maintaining the reactor at elevated pressures during the process.

摘要： Briquettes useful as fuel are produced from dehydrated sewage sludge containing 65 weight percent or more sewage sludge solids. The briquettes on a dry basis contain from about 50 to about 95 weight percent sewage sludge solids together with from about 3 to about 12 weight percent lime as binder and fungistat. Organic binders and coking agents may be included in the briquettes to improve resistance to breakage and to impart high crush strength at elevated temperatures encountered in gasifiers.

摘要： Briquettes of specified geometry and composition are produced to serve as feed material or "burden" in a moving-burden gasifier for the production of a synthesis or fuel gas from organic solid waste materials and coal, including especially, the so-called "caking" coals, as in the process of copending application number 675,918. The briquettes are formed from a well-blended mixture of shredded organic solid wastes, including especially, municipal solid waste (MSW) or biomass, and crushed caking coal, including coal fines. A binder material may or may not be required, depending on the coal/MSW ratio and the compaction pressure employed. The briquettes may be extruded, stamped, or pressed, employing compaction pressures in excess of 1000 psi, and preferably in the range of 2000 to 10,000 psi. The briquettes may be circular, polygonal, or irregular in cross-section; they may be solid, or concentrically perforated to form a hollow cylinder or polygon; they may be formed into saddles, pillows or doughnuts. The ratio of caking coal to shredded municipal solid waste is controlled so that each part of the predominately cellulosic organic solid waste will be blended with 0.5 to 3.0 parts of crushed coal. Suitable binder materials include dewatered sewage slude (DSS), "black liquor" rich in lignin derivatives, black strap molasses, waste oil, and starch. The binder concentration is preferably in the range of 2 to 6 percent. If coals high in sulfur content are to be processed, at least a stoichiometric equivalent of dolomite may be included in the briquette formulation to eliminate a major fraction of the sulfur with the slag.

摘要： Pellets or briquettes useful as fuel are produced from sewage sludge solids. Mechanically stable pellets or briquettes result from combining a major portion of sewage sludge solids with lesser amounts of lime and binder materials suitable for imparting stability to the product and pressing or extruding the combined components into desired shapes. Coal may be included in the pellet or briquette composition for improved fuel value.

摘要： A method and apparatus for removal of PCBs or similar refractory organic substances from solid surfaces, such as soil or hardware, e.g., capacitors and transformers containing a charge or residue of PCB or similar fluids. Such toxic substances are volatilized from substrates contaminated therewith by contacting them with carrier gas, such as a mixture of hydrogen, carbon monoxide and steam. The carrier gas and volatilized components are introduced into a partial oxidation zone of a gas generator where PCBs are completely destroyed at a temperature range of 2800.degree. F. to 3500.degree. F.
