摘要： An apparatus for safely evacuating a person within a prescribed weight range from a multistory building by enabling the person to exit from the interior of the building to the outside very quickly and to descend to the ground or lower surface alongside the exterior of the building to attain a descent speed of less than four feet per second to land injury-free, the apparatus comprising a housing, a harness affixed to the housing for affixing the housing to the person, a cable of predetermined length within the housing, having a free-end with a securing member for affixing it to an anchorage proximate the descent point, and a descent slowing energy dissipating mechanism within the housing driven by the playout of the cable as the person descends, which enables the person to attain automatically within his descent a descent speed of less than four feet per second determined by the intersection of the graph of the curve that describes the rate of energy dissipated as a function of the descent speed and the graph of the line that describes the rate of potential energy released by the total descending weight as a function of descent speed where the slove of the graph of the rate of energy dissipated curve exceeds the slone of the graph of the rate of potential energy released line.

摘要： A method and apparatus for on-line detection of leaky emergency shutdown or other valves in a fluid transport system having an upstream pipe, a downstream pipe and the valve connected between the upstream pipe and the downstream pipe for controlling fluid flow through the system. The valve has at least one upstream seal and at least one downstream seal and an inner cavity effectively isolated by the seals from the fluid flow stream through the system. The apparatus comprises a first transducer in fluid communication with the fluid flow stream at at least one of: a predetermined distance upstream of the upstream seal; and a predetermined distance downstream of the downstream seal. The first transducer is for sensing pressure pulsations resulting from at least one of: dynamic energy due to fluid flow through the transport system; and transient energy within the fluid in the transport system after the valve is closed and for generating representative electrical signals as a function of time. A second transducer is in fluid communication with the inner cavity of the valve for sensing substantially simultaneous pressure pulsations within the inner cavity and for generating second representative electrical signals as a function of time. An analyzer receives the first and second electrical signals and generates at least one of: a frequency response function; and a coherence function. The generated function is sufficiently averaged to provide a meaningful measure of the degree to which the two electrical signals are related to thereby indicate whether, and to what extent, sensed pressure pulsations within the fluid transport system are passed through at least one of the seals to the inner cavity.

摘要： A device for measuring strain parameters of a stem, shaft or other cylindrical member of virtually any size or diameter includes a pair of generally flexible holders, each holder supporting a substrate having at least one strain gage thereon. Each substrate is bonded in a predetermined aligned position on the cylindrical member relative to the other substrate to permit strain measurement of the cylindrical member. The holders each include at least one guide. A flexible tensioning band engages the guide on each of the holders for placement and retention of the substrates in the predetermined positions. The band is tightened to provide pressure on the substrates during bonding for proper bonding of the substrates to the cylindrical member to provide adequate transfer of strain. In an alternate embodiment a single holder having a single strain gage substrate thereon is employed.

摘要： A method for determining at least one operating parameter to determine the operating condition of a polyphase electric motor system comprises sensing the instantaneous current signal and the instantaneous voltage signal as a function of time for more than one electrical phase of the motor. The sensed current signals and the sensed voltage signals are both amplitude demodulated and phase demodulated to provide amplitude demodulated current and voltage signals as a function of time and phase demodulated current and voltage signals as a function of time. The resulting amplitude and phase demodulated signals are used to determine one or more of the following electrical parameters as a function of time: total real power, real power per phase, total reactive power, reactive power per phase, total apparent power, apparent power per phase, overall power factor, power factor per phase, electrical impedance per phase, and electrical balance.

摘要： A system to determine the position of an electrically conductive element movably positioned in a housing, like a metal disc in a check valve, includes an A.C. electromagnet positioned in close proximity to the valve casing and the disc. The magnet is excited with an A.C. voltage to generate a magnetic field which penetrates the casing and the disc. The magnetic field is detected by a sensor. A.C. current and voltage signals from the electromagnet and a magnetic field signal from the sensor are presented to a processor portion of the system. The processor portion digitizes, amplitude and phase modulates each of the three signals and generates four traces: A.C. current amplitude, magnetic field amplitude, A.C. current phase and magnetic field phase. The latter two traces are derived with respect to an A.C. voltage phase signal. Comparable baseline signals previously gathered for the valve are stored. One to four of the traces are displayed, with or without the corresponding baseline trace, for determination of disc position.

摘要： A controller for controlling the operation of a motor operated valve combination, including a valve yoke, a valve stem, a valve disc, a valve seat and a motor operator having a motor and drive means interconnecting the motor to the valve stem for movement of the valve stem in a first direction to move the valve disc into engagement with the valve seat for closing the valve. The controller comprises a sensor for sensing forces experienced by the valve stem during valve closing and for generating related electrical signals. A first detector is employed for receiving the electrical signals from the sensor, for determining when the rate of change in the valve stem forces exceed a first predetermined limit and for generating an electrical signal when the first predetermined limit is exceeded. A second detector receives the electrical signals from the sensor and from the first detector, determines when, after receipt of the signal from the first detector, the forces experienced by the valve stem exceed a second predetermined limit and generates an electrical signal in response thereto. Motor cut-off circuitry receives the electrical signal from the second detector and stops the operation of the motor in response.

摘要： The present invention comprises a thrust actuated control for use in a motor operated valve having a motor operator including a motor drive, a stem nut coupled to the motor drive for rotation about an axis and a stem nut lock coupled to the motor drive for preventing axial movement of the stem nut. The valve includes a valve gate, a valve seat and a valve stem coupled to the valve gate, the valve stem threadingly engaging the stem nut for axial movement in a first direction upon rotation of the stem nut in a first direction to move the valve gate toward and into engagement with the valve seat and for axial movement in a second direction upon rotation of the stem nut in a second direction to move the valve gate out of engagement with and away from the valve seat. The improvement comprises a thrust sensor positioned between the stem nut and the stem nut lock for sensing axial displacement of the stem nut in the second axial direction resulting from axial compressive thrust on the stem caused by continued rotation of the stem nut in the first direction after the valve gate is in engagement with the valve seat. A switch is operatively coupled with the thrust sensor and with the motor drive for actuation to stop the operation of the motor drive to stop rotation of the stem nut when the axial displacement of the stem nut exceeds a predetermined limit proportional to a predetermined axial compressive thrust on the stem.

摘要： A device for measuring and indicating the forces on a valve stem over at least a portion of the valve strokes is comprised of a strain sensor secured to the valve yoke for sensing strains experienced by the valve yoke. The sensed strains are proportional to the forces on the valve yoke and are equal but opposite to the forces on the valve stem. The strain sensor generates electrical signals proportional to the forces on the valve stem. A display, electrically connected to the strain sensor, is provided for receiving the generated electrical signals and for indicating the forces on the valve stem. A system for evaluating the performance of a valve and valve operator also utilizes the yoke strain sensor in combination with other sensors, including a valve stem motion sensor, a spring pack motion sensor, a motor current sensor and, possibly, a stem strain sensor, as well as an indicator of the condition of torque and limit switches.
