  • Patent number: 10889511
    Abstract: A fluid conditioning and treatment system generally comprising an electronic controller component in communication with an energy delivery module (“energy chamber”) through an interconnecting cable. The electronic controller can be housed in a fiberglass enclosure and develops and transmits preprogrammed high-energy electronic signals to the energy chamber through the interconnecting cable. The energy chamber can have a series of computer designated, matched, electrodes placed through its walls. The electrodes contact the fluid flowing through the energy chamber. Each of the controllers circuit boards are programmed to produce precisely a given range of electronic output signals that when applied to the fluid accomplishes specific functions. The controller can be programmed to supply a number of electronic hits that are applied to the water as the water passes through the energy chamber.

  • Patent number: 9175799
    Abstract: A modular pipe repair enclosure system includes first and second enclosure portions, and an enclosure attachment device. The first and second enclosure portions create an enclosure around the pipe for covering leaks. The enclosure has three openings for accommodating the pipe. The first and second openings are arranged at an angle of 180 degrees with respect to each other, and at an angle of 90 degrees with respect to the third opening, such that a straight line section of pipe may be accommodated by the first and second openings, an elbow section of pipe by the first and third openings, and a T-section of pipe by the first, second, and third openings. The system may further include a blank, for closing one of the openings, for use with a straight or elbow section, and a sleeve, for reducing the inner diameter of an opening, for accommodating pipes of different diameters.

  • Patent number: 7413666
    Abstract: An improved method for isolating the impacts of flow-altering events in corrosion transport from those due to steady state corrosion in boiler/steam cycle processes. The method includes monitoring, in real time, with a particle counter or particle monitor levels of suspended particles in a fluid flow stream and of automatically collecting insoluble particulates large enough to be captured on a 0.45 micron filter when, and only when, these levels exceed an “event threshold”. For use in subsequently characterizing flow-altering events without necessarily weighing the collected particulates for each excursion above this threshold, an average particle count/particle index is obtained and compared with the actual weight of insoluble particulates captured. When excursions are highly infrequent, concentrations of insoluble metal oxides likely to be present in the flow stream and capable of producing above-threshold PC/PIs can be determined and used to identify anomalies when particulates are captured.

  • Patent number: 7303685
    Abstract: A feedback control for a polymer dispensing system, which otherwise continuously adjusts the polymer feedrate so as to keep the measured streaming current of filtrate from a sludge dewatering process at one predetermined setpoint. The feedback control includes a video camera focused on sludge as it trails behind plows on a dewatering belt, a video image processing system for converting the video signal into single numbers known as “camera readings”, and a computer programmed both to compare them with a “camera reading” setpoint and to determine whether the filtrate charge is more positive or more negative than it normally is whenever the “camera reading” deviates from its setpoint by a threshold amount. A controller, activated by the computer, incrementally resets the polymer feedrate in such a direction as to restore the normal cationic charge of the filtrate.

  • Patent number: 6326703
    Abstract: Ethanol fuel is fed into hot burn chamber of twin turbine, initially to burn in the presence of compressed air. After turbine in hot burn chamber is started, water is electrolyzed by means of DC current produced by DC generator on turbine shaft, and resulting hydrogen and oxygen gases are pumped into hot burn chamber and are ignited by the burning ethanol fuel to produce products of combustion which continue to drive the turbine.

  • Patent number: 5077722
    Abstract: An interlock for a disk drive unit having a handle and a camming arrangement responsive to pivotal movements for inserting and withdrawing the unit from a housing fixture. A solenoid is actuable to lock the handle when the unit is fully inserted. A sensor is adapted for sensing an interlock engagement between the solenoid armature and the handle. For removing the disk drive unit, a delay is interposed before retracting the solenoid armature to assure that the disk drive unit is fully stopped before the handle can be rotated for removal of the unit.

  • Patent number: 4620275
    Abstract: A vector processing computer is configured to operate in a pipelined fashion wherein each of the functional units is essentially independent and is designed to carry out its operational function in the fastest possible manner. Vector elements are transmitted from memory, either main memory, a physical cache unit or a logical cache through a source bus where the elements are alternately loaded into the vector processing units. The vector control unit decodes the vector instructions and generates the required control commands for operating the registers and logical units within the vector processing units. Thus, the vector processing units essentially work in parallel to double the processing rate. The resulting vectors are transmitted through a destination bus to either the physical cache unit, the main memory, the logical cache or to an input/output processor.

  • Patent number: 4039439
    Abstract: A method for generating hydrogen bubbles electrolytically in the lower reaches of a body of water which is normally highly saturated with hydrogen; controlling the bubble size of the hydrogen bubbles within a range of from 100 to 600 microns so the hydrogen bubbles function as a vehicle to raise the oxygen deficient water to the surface, but the hydrogen bubbles substantially remain in the water near the surface of the body of water, moving along the surface thereof and move outwardly in a path therealong exposing the water so carried to natural aeration and sunlight; the range of the bubbles size being such as not to adhere to solid materials and carry them to the water surface to eliminate turbidity and the formation of floc.
