  • Publication number: 20200228023
    Abstract: Capacitive switching device and method utilizing capacitive methods, switch mechanisms and structure to switch on and off of the transfer of alternating current (AC), pulsed power or signals from input side to an output side. More specifically, the present invention relates to AC or pulse decoupled structure which electrically and electronically provides the means to instantaneously switch on and off the transferring forward of power or signal from input terminal connections to output terminal connections. By controlling electrostatic charges to migrate, or not to migrate from its input electrodes to its output electrodes, power or signal transfer forward is controlled.

  • Patent number: 9438129
    Abstract: Input/output power and signal transfer and power and signal isolator device using pulsed, alternating or high frequency signal current having a capacitive structure which provides power and signal limiting control, unidirectional power and signal transfer and input/output decoupling and transceiver-receiver isolation barrier. The device includes at least two decoupled input electrodes arranged in parallel to each other, and at least two decoupled output electrodes arranged in parallel to each other. Each electrode is connected to at least one terminal. Each electrode has a surface that which is opposed to another electrode surface with at least one layer of dielectric material therebetween. The input electrodes are decoupled from the output electrodes by dielectric material and are disposed such that two output electrodes are separately disposed external to the two input electrodes.

  • Publication number: 20140034559
    Abstract: The present invention relates to a means of monitoring and controlling a process step, or steps for a treatable fluid being processed, whereby a sampled volume of the treated fluid is delivered to a vessel, within which the sampled treated fluid emulates the expected reaction or reactions of the treatable fluid being processed within the process step. The sampled volume of the treated fluid is detained, monitored, recorded and analyzed by the present invention. The resulting data is translated into commands that are conveyed to process control devices which control the processing of the treatable fluid. Sampling and analyzing of the treatable fluid is automatically repeated on a cyclical basis.

  • Patent number: 7695630
    Abstract: An ionic conditioning process and molecular arrangement for removing colloids from an aqueous solution, where the aqueous solution is transported to and/or through several conditioning zones for purification. The process utilizes vessels within which stages of conditioning are performed and are monitored. The conditioning processes perform ionic, chemical and physical conditioning to the colloids in the aqueous solution causing the colloids to be transformed into a state that reacts with a polymer flocculating agent and is thereby precipitated rapidly and efficiently for removal. The effluent as well as the precipitate can be further treated with conventional means to meet certain specifications for discharge and disposal.

  • Publication number: 20070289922
    Abstract: A Modular Wastewater Treatment System is disclosed suitable for municipal, domestic and commercial sewage. After separation of the settable solids of the wastewater in the collection system or septic tank or other means the effluent is passed by gravity to the Alternating Nitrification Enhance Reactor where nitrification and de-nitrification process occurs as well as BOD sub.5 and TSS reduction by the participation of a facultative colony. Dosing, recirculation and discharge systems are linked in the alternating and intermittent cycles and facultative process with a gravel media bed to remove the remaining BOD sub.5, TSS and fecal coliform counts of the effluent. The overall system save footprint and it is fully automatic.
