    摘要： A regenerative feedback resonant circuit for measuring a transient response in a loop is disclosed. The circuit includes an amplifier for generating a signal in the loop. The circuit further includes a resonator having a resonant cavity and a material located within the cavity. The signal sent into the resonator produces a resonant frequency. A variation of the resonant frequency due to perturbations in electromagnetic properties of the material is measured.

    摘要： An incinerator/combustor, comprising an elongated combustion chamber surrounded by an afterburner which is in turn surrounded by a housing, the afterburner and housing being coaxial with, and cooperating to provide redundant heating for, the combustion chamber, is disclosed. The combustion chamber is generally cylindrical with a horizontal axis, one end being adapted to receive materials to be burned. An ash chamber is spaced from the other end of the combustion chamber to define a circumferential opening which serves as an exhaust outlet. The two chambers are relatively movable to permit the flow of exhaust gases to be controlled. Air under controlled pressure is introduced to the combustion chamber to produce a cyclonic flow to enhance burning. A fuel supply may be provided to initiate combustion, but the system is designed to require no fuel other than the material being incinerated during normal continuous operation.The afterburner extends over both the exhaust outlet and a major portion of the combustion chamber. Air under pressure directed across the exhaust outlet produces a Venturi effect to draw exhaust gases out of the combustion chamber and direct them into the afterburner. The outer housing receives exhaust gases from the afterburner and directs them back over the outside surface of the afterburner in a second redundant flow, carrying them to an outlet stack.

    摘要： A method and an apparatus for treating materials in a combustor are disclosed. A pair of axially aligned slide gates extend longitudinally through the combustion chamber of the combustor. The innermost ends of the gates abut when the gates are closed, with the gates being openable by moving them axially apart to define a treatment aperture. Movement of the two gates permits the aperture to be positioned at a desired location in the combustion chamber, while movement of one gate with respect to the other adjust the width of the aperture.

    摘要： A technique for installing a fiber optic network includes preparing a physical site to install a feeder cable and a plurality of access stub lines along a plurality of customer premises that potentially may connect to the feeder cable to obtain communication services. Each of the access stub lines extends from the feeder cable towards a customer premise and each ends at a different initial termination point. There is a one-to-one correspondence between the customer premises and the access stub lines extending from the feeder cable. A demarcation device is attached to an end of each of the access stub lines at each of the initial termination points. The demarcation device includes an optical reflector that is reflective to an optical test signal for testing integrity of the feeder cable and an associated one of the access stub lines.

    摘要： Implementations of techniques and systems are disclosed for detecting a fiber fault in a point-to-point optical access network based on optical time domain reflectometry (“OTDR”) measurements. The techniques include identifying loss of service between a central office (“CO”) and a given optical network unit (“ONU”) of a plurality of ONUs. In response to the identifying the loss of service, configuring a test signal distribution unit to optically couple an OTDR unit to a selected subset of the point-to-point fiber links which includes the given ONU. An optical test signal is launched from the OTDR unit into the selected subset of the point-to-point fiber links via the test signal distribution unit. Test signal reflections are received from each of the point-to-point fiber links within the selected subset as a reflection signature, which is analyzed to identify a location of the fiber fault.
