  • Patent number: 4808916
    Abstract: A self contained sensor module mounted on a power transmission line. The module is capable of measuring various parameters such as line current, voltage, conductor temperature and ambient temperature. The parameter values are processed by sensor electronics which digitize and periodically transmit the values to a ground receiver. The module power supply is coupled to the transmission line conductor by a transformer. The line conductor extends through a magnetic core in the module housing. A secondary shunt magnetic core is provided to limit induction of high voltages as a result of excess current flowing through the transmission line conductor.

  • Patent number: 4796027
    Abstract: Self contained radio transmitting modules are mounted on power conductors at various places along electrical transmission lines. The modules are capable of measuring current, voltage, frequency and power factor (or the Fourier components thereof), the temperature of the conductor and the temperature of the ambient air. Up to fifteen modules may transmit on a single channel to a single local receiver. Each module transmits at intervals which are an integral number. The intervals between transmissions of all modules do not have a common factor and the average interval is the desired transmission rate.

  • Patent number: 4795973
    Abstract: A self contained hot stick mounted radio transmitting module may be permanently mounted on or temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the potential difference between the conductor and ground. The module digitizes and transmits the value of the potential difference to a ground receiver. The module is donut shaped and opens like a pair of jaws. The contact with the power line is accomplished via a resilient conductive elastomer that covers the surfaces in contact with the power conductor. The potential difference between ground and the power conductor is measured with an operational amplifier in an integrating configuration to convert the leakage current from the module to ground into a proportional voltage from a low impedance source. The integrator outputs a voltage proportional to the current flowing into the equivalent capacitance formed by the outer surface of the module and ground.

  • Patent number: 4794328
    Abstract: A "hot-stick" mountable sensor module for attachment and removable from a live power transmission line. A tool is insertable into a mounted module to attach the module to the tool and permit removal of the module from the line.

  • Patent number: 4734604
    Abstract: A friction braking system located entirely inside an induction motor of an appliance quickly stops rotation of the rotor in the appliance motor, for example such as a food processor, whenever the A.C. electrical power is turned off. Thus, rotation of any tool being operated in the appliance is quickly stopped, whenever the electrical power is interrupted. The rotor in the induction motor is axially slidably mounted on the motor shaft and is keyed to the shaft for permitting axial shifting displacement of the rotor relative to the stator while preventing any angular displacement of the rotor relative to the shaft. Consequently, the rotor and shaft always turn and stop as a function unit. A friction brake lining is affixed within the motor housing offset from the axis of the motor shaft as far as practicable. A disc brake mounted onto the rotor has an annular friction braking surface positioned for engagement against the brake lining.

  • Patent number: 4723220
    Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. The module measures the Fourier components of voltage and current over a number of cycles and transmits the components to the local receiver.

Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer.

  • Patent number: 4635055
    Abstract: A self contained hot stick mounted radio transmitting module may be temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the temperature of the conductor, and the temperature of the ambient air. It may also measure the electrical potential of the conductor. An alternative module is also capable of measuring current, potential, frequency and power factor (or the Fourier components thereof). The modules transmit these parameters to a local receiver where the data may be displayed. The receiver also may be connected by an appropriate data transmission link, to a power control center.The modules are donut shaped and open like a pair of jaws. One or more spring loaded temperature probes are located such that they may be pushed against a power line when a "donut" is mounted to a hot stick with the jaws open.Power to an open module is supplied by a battery.

  • Patent number: 4148480
    Abstract: An acoustic pin detecting and locating device is disclosed, comprising a linear array of transducers mounted on each kickback wall. A microprocessor sequentially energizes each transducer with a short burst of high frequency pulses; the reflections from standing pins to the transmitting transducer (direct data) and the next adjacent transducer (cross data) are gated into separate a/d converters. The converters are sampled periodically to divide the signal return to each transducer into a plurality of range cells. The direct data and cross data returns to each transducer array from two data fields. Analysis of these two fields provides the information needed for detection of the location of each standing pin. The data return to each transducer after each acoustic burst is peaked by comparing the magnitudes of echo signal returns in adjacent range cells. A string is formed for each significant return, including the x,y coordinate position of the return; the weight of the return and its first and second moments.
