Abstract: An economically viable process for the microwave destruction of contaminated water-based liquids, such as by chemical and biological agents, employs carbonaceous materials to enhance the efficiency of the microwaves while keeping the bulk temperature down to only a modest rise. A second absorption reactor is used not employing microwaves. The cyclic microwave use of both reactors allows high efficiency for the total process of destruction—adsorption.

Abstract: A livestock mixer and feeder apparatus operates efficiently to minimize the time and facilities necessary to service a modest feedlot. The large mixing chamber utilizes a vertical auger operating at high speed to quickly perform the mixing procedure and is run by a high power hydraulic motor. A moveable base, such as a pickup, supplies the need power-take-off capability and produces efficient feedlot operation, since the apparatus can be quickly loaded and unloaded. Prudent sized inlet and outlet augers complete the apparatus and are also powered by hydraulic motors.
Abstract: A process of gas purification occurs in the presence of radiofrequency microwave energy and carbonaceous material by decomposing adsorbed impurities on a bed surface at near ambient conditions of temperature and pressure. Further microwave enhanced catalytic oxidation to purificatory gases normally occurs.
Abstract: The subject invention is a commercial device to effectively remove NOx and other pollutants from an exhaust gas stream. Microwave enhancement of oxidation/reduction catalysis is selectively employed as the exhaust gas stream traverses a bed of catalyst particles, which may operate as either a fixed or fluidized bed. An unique feature involves the conventional, non-microwave, conversion of NO to NO2; however, the subsequent reaction of reducing NO2 is microwave enhanced.
Abstract: A process of air purification occurs in the presence of activated carbon or its equivalent by decomposing adsorbed hazardous materials, such as volatile organic compounds, on the carbon surface by radiofrequency energy in the microwave range at near ambient conditions of temperature and pressure. Further microwave oxidation to nonhazardous gases occurs in the presence of an oxidation catalyst.
Abstract: This process occurs in the presence of activated carbon or its equivalent by decomposing adsorbed hazardous materials, such as hydrazine and microorganisms, on the carbon surface by radiofrequency energy in the microwave range at near ambient conditions of temperature and pressure. Further microwave oxidation to nonhazardous gases occurs in the presence of a microwaves enhanced oxidation catalyst.
Abstract: Gaseous decomposition from a solution is enhanced in the presence of activated carbon or its equivalent by radiofrequency energy in the microwave range. An important example is wet calcination using solutions containing bicarbonates, such as trona, where good conversion to carbonate is readily obtained. A further example is the excellent stabilization of solutions containing sulfites and bisulfites.
Abstract: Wet oxidation is enhanced in the presence of carbonaceous material by oxidizing adsorbed organic materials, such as hydrazine and various solvents which may contain, or have dissolved or mixed compounds containing, chlorine molecules, on the carbon surface by radiofrequency energy in the microwave range at near ambient conditions of temperature and pressure. The discharged water is substantially environmentally clean.
Abstract: The subject invention is a process and device to effectively remove combustion pollutants under oxygen conditions greater than six volume percent. Microwave enhancement of oxidation/reduction catalysis is selectively employed in a multiple step process. However some of the steps do not utilize microwaves as they convert NO to NO.sub.2 by employing a conventional oxidation catalyst, and which then in a subsequent step which does employ microwaves uses a reducing agent to undergo catalytic reduction to N.sub.2.
Abstract: A system consisting of a versatile hitch attached to a tractor which positions a ground-based implement, such as a mower, in front or to either side of the tractor. The hitch cushions or dampens movement using a torsional component over rough ground by the tractor allowing the implement to traverse a near parallel ground direction. The mower design mows either normally over open ground or in restricted locations, such as around fences supported by posts.
Abstract: An aligning tool, involving plumb bob usage, for a fully assembled underground elevator ram system is provided and makes it possible to align the elevator ram into a required vertical position. Further this allows the fully assembled elevator to be vertically installed at site in a hole which often is flooded by groundwater.

Abstract: A thermal process co-recycles tires with oils to produce gases, liquids and solids. The latter consisting of glass and steel fibers and a carbonous residue which are separately segregated and collected. By using selected additives gas formation and hydrogen sulfide contents are reduced, light product oil yields and quality are maximized and the level of chlorinated substances in the oils are reduced to trace amounts. The carbonous residue makes an excellent modifier for improving performance properties of bituminous binders and bituminous mixtures and for providing added benefits to properties of Portland concrete.

Abstract: A process is disclosed for cleaning carbonaceous deposited material from the inside of pipes or tubes by utilizing microwave catalysis to dynamically remove such soot-like material as it chemical reacts with oxygen supplied by a sweep gas to form gaseous products. The metallic pipe is converted to a waveguide by the use of appropriate frequencies of microwave energy. The soot-like material is catalyzed by the microwave energy so that any oxygen reactions occur at a relatively low bulk temperature.
Abstract: A multi-purpose door for a service compartment having several locking open positions which protects the contents of the compartment when closed, offers some protection for the person using the compartment from the weather when open, and further allows when open, effective storage use of the overhead roof area of the compartment. Under adverse conditions a waterproof material is attached to further protect the person.
Abstract: A potentially economically viable apparatus is provided for the containment and detection of underground leaking fluids by employing a wrapper, often in the form of a conduit, to enclose the underground portion of a hydraulic fluid system. An important application is the detection and containment associated with an underground elevator system using hydraulic oil.
