  • Patent number: 6830681
    Abstract: Device and method for keeping and growing aquatic organisms by optimizing the microbiological treatment of water. The device comprises a first chamber for holding oxygen-depleted water and a second chamber for holding oxygen-rich water, the first and second chambers being separated from one another by a porous substrate which comprises micro-organisms. In the active state, water circulates in the device across the porous substrate for the purpose of microbiological treatment. Using means for conditioning the oxygen-depleted water and oxygen-rich water next to one another results in the composition of the water being effectively kept at optimum values for the microbiological treatment of the water. In addition, sediment comprising waste matter is removed by separation means which are incorporated in an oxygen-depleted circuit and in an oxygen-rich circuit; this prevents the water from becoming turbid and prevents the accumulation of waste matter in the form of sediment.

  • Patent number: 6814807
    Abstract: An apparatus for applying metered fluid such as sizing to an advancing individual yarn in a uniform manner. An elongated member includes at least one slot for receiving the advancing yarn and to bring the advancing yarn into contact with the metered fluid. The slot is defined by a width, a height and a length for affecting the distribution of the fluid on the advancing yarn. The length of the slot is dependent on the speed of the advancing yarn. The advancing yarn has a predetermined residence time in the slot as a function of the length of the slot and the speeding of the advancing yarn in the slot.

  • Patent number: 6780227
    Abstract: A species transfer device in communication with at least two streams, one stream having a higher potential of a species than a lower potential stream. The species transfer device is capable of removing a portion of the species from the high potential stream, and transferring the removed species into the low potential stream. The species transfer device incorporates a housing assembly, exchange matrix and optionally, a sorbent. The housing assembly contains both the exchange matrix and optionally a sorbent inside a housing enclosure and between a sealing enclosure, and provides for the entrance and exhaust of the first and second streams therethrough. The exchange matrix can be, but need not be, in the form of a wheel having an average linear coefficient of thermal expansion at 25 to 800° C. of less than about 20×10−7/° C. The housing assembly with the housing and sealing enclosures enables the species transfer device to run efficiently through a range of pressures.

  • Patent number: 6774822
    Abstract: Methods and systems for filtering an analog signal sampled at a very high frequency and outputting a digital signal that has a very low sampling frequency to drive a material metering machine. The high frequency digital input signal is input to a first decimation element, which filters out the noise in the signal introduced by an analog-to-digital (A/D) converter and reduces the sampling frequency of the digital signal to a lower sampling frequency of 1200 hertz. The reduced rate digital signal is input into a second decimation element that contains several decimation filters, which reject the 60 hertz line noise and its harmonics while simultaneously reducing the sampling frequency of the digital signal to 10 hertz. The output of the second decimation element is then passed to a bank of selectable filters with sub-hertz cutoff frequencies to remove the machine noise from the material metering machine.

  • Patent number: 6767008
    Abstract: A diffuser for use in a pressurized feed system. The diffuser introduces a carbonic acid solution into water to be treated. The carbonic acid solution within the diffuser is maintained at an elevated pressure. As the carbonic acid solution passes to the exterior of the diffuser, the pressure drop causes an effective mixing of the carbonic acid solution and the water. The carbonic acid solution mixes with the water and the pH of the water is reduced.

  • Patent number: 6756352
    Abstract: An aqueous cleaning composition fluid foam containing an alkali metal hypochlorite has a particular combination of precursor solution relative viscosity, foam syneresis value, foam horizontal thickness half-life and foam vertical wall clingability, and compared to known hypochlorite-containing cleaning compositions, provides superior cleaning of stubborn mildew, normally without scrubbing. The cleaning composition fluid foam is produced by vigorous agitation of an aqueous hypochlorite solution containing an alkaline builder and a surfactant in the presence of a gas, or by injection of a pressurized propellant into an aerosol dispenser containing such solution and then passing the solution/propellant mix through a mechanical break-up actuator in the valve assembly of the aerosol dispenser.

  • Patent number: 6627428
    Abstract: The present invention is directed to a microbially-driven Fenton reaction for the transformation of organic contaminants. The microbially-driven Fenton reaction combines abiotic and biotic reactions in one system by utilizing the H2O2— and Fe(II)-producing microorganism Shewanella putrefaciens to generate Fenton reagents as metabolic by-products of alternating aerobic and anaerobic respiration. Accordingly, the present invention is directed to a process for oxidatively degrading organic contaminants comprising reacting Fe(III) citrate with S. putrefaciens under alternating anaerobic and aerobic conditions to generate Fenton reagents Fe(II) and H2O2, further reacting the Fenton reagents under neutral pH conditions with the organic contaminant to produce degraded transformation products of the contaminant.
