  • Patent number: 9603609
    Abstract: An energy supplier of an ultrasonic treatment system can output an electric power in a first output mode and a second output mode in which the electric power supplied to a drive force generation unit during a unit time is higher than in the first output mode. A controller maintains an output state of the electric power in the first output mode when a judgment section judges that a load on an ultrasonic probe is less than or equal to a threshold, and switches the output state of the electric power to the second output mode when the judgment section judges that the load is more than the first threshold.

  • Publication number: 20090314625
    Abstract: A method and apparatus for a steam biomass reactor converts organic waste placed inside a sealed steam injected reactor to biogas (methane CH4 and carbon dioxide CO2). The amount of liquid introduced into the reactor can be minimized, increased methane and CO2 can be produced, and the methane produced can have higher Btu values as compared to methane produced in other reactors. Some embodiments provide a method of injecting steam into a sealed vessel that is loaded with organic waste and collecting the methane produced by accelerated decomposition/biodegradation of the organic component of the waste within the vessel. The steam accelerates the decomposition of the organic refuse, thereby enhancing the production of methane gas and CO2.

  • Patent number: 6756909
    Abstract: Failures associate with bad hand pieces and blade failures in an ultrasonic surgical system are distinguished by monitoring the rate of change of the resonance frequency and the rate of change of the resonance impedance of the hand piece/blade as the drive frequency is changed. As the system reaches resonance, the control system locks onto the resonance frequency. When a loss of lock occurs with no recovery, the rate of change of the frequency and rate of change of the impedance are compared to obtain the fastest rate of change which is stored in non-volatile memory of the ultrasonic generator. If the rates of change are higher than normal rates of change due to temperature changes with the longest blades, a “Bad Blade” message is displayed on an LCD.

  • Patent number: 6387221
    Abstract: Garbage and waste of all types that includes or comprises organic matter, particularly including medical waste, plastics, paper, food waste, animal by-products, and the like, can be economically recycled into petroleum products, including oil. Machinery performs a method that mimics natural processes but accomplishes the task in minutes, at rates of about 15 tons per day in a typical processing machine, rather than taking hundreds of thousands of years in nature. The process and apparatus of the invention may chop the waste into small pieces, under negative pressure if appropriate, and then pass the waste into first and then second augers for compression and heating. Destructive distillation occurs, in which large molecular weight hydrocarbons and petrochemicals are heated by hot oil passing through the hollow shaft and by circulating hot, dense, hard material, such as steel balls or fragments or hard rock pieces and such, under pressure with steam, to produce low molecular weight hydrocarbons.

  • Patent number: 4980029
    Abstract: Gaseous, liguid and solid fuels are recovered from carbonaceous organic waste material by treating charges of waste material in several successive stages including preheating, drying and conversion into solid and gaseous phases, all as a result of heating in a common vessel or in two or three successive vessels. The solid phases are thereupon cooled prior to admission into a bin, either in a separate vessel or in the vessel for conversion into solid and gaseous phases. The gaseous phases are treated to separate oil from reaction water, combustible gases and inert gases. The charges are heated from without and are sealed from the atmosphere during all four stages of treatment. Each charge is mixed during heating and the intensity of mixing action, the heating action and/or the pressure in the vessel can be varied during one or more stages.

    Abstract: Apparatus and system for producing high pressure gas, such as high pressure coal gas from coal, air and water. Pulverized coal is introduced into a rising stream of steam in a central reaction column of a retort to constitute a fluidized or entrained bed. The coal reacts with the steam to form a gas consisting of hydrogen, carbon monoxide, carbon dioxide, nitrogen, methane and higher hydrocarbons. The retort is constructed so that product gas and air may be burned in an annular chamber surrounding the central reaction column to produce hot flue gas. The hot flue gas is used to drive a turbine which in turn, drives a compressor which introduces compressed air into the annular chamber. Steam tubes may be disposed in the annular space so that the steam introduced to the central reaction chamber may be super-heated by the hot flue gas.

  • Patent number: 4122036
    Abstract: A method of pyrolyzing sewage sludge to transform the same into activated carbon, with the combustible pyrogas and volatile liquids included therewith that arise from the pyrolysis operation being burned to sustain the transformation operation. A first portion of the hot activated carbon resulting from the operation is mixed with the wet sewage sludge to provide a dry sludge mixture that is subsequently subjected to the pyrolyzing operation. Water vapor that discharges as the hot activated carbon is mixed with the wet sewage sludge is heated by the burning of the pyrogas and transformed to steam. The resulting steam is in contact with the dry mixture during the pyrolyzing operation, and as a result the dry mixture is transformed to activated carbon. A second portion of the resulting activated carbon is separated from the first portion thereof, with this second portion being available for use apart from the method.
