    摘要: A remote indicator displays data contained in a transmitted signal by angular displacement of a rotor. In essence, the indicator comprises a rotatably mounted magnetic rotor, a plurality of controllable magnetic field generators disposed circumferentially around the rotor, and appropriate selection circuitry. A sector selection circuit responsive to the transmitted data selectively enables at proper polarity a plurality of generators appropriate for controlling the rotor within the sector representative of the data, and an angle selection circuit responsive to the transmitted data alternately drives selected generators by electrical pulses time modulated to drive the rotor within the sector to the angular position representative of the transmitted data. Distortions due to residual magnetism are substantially eliminated by the use of AC pulsing, and non-linear salient pole effects are eliminated through the use of look-up table techniques.

    摘要: A remote reading magnetic compass operative with only two electrical connections for both power and data purposes. The compass includes a disc which is photoelectrically sensed to provide output signals representative of compass heading and is supported by a gimbal assembly including pivots which serve as electrical terminals by which energizing power is supplied to the compass electronics and by which data is read out from the compass.

    摘要: The present invention is designed to be mounted over a flaming oil wellhead to extinguish the flames. The invention includes a base having hydraulically operable arms designed to allow secure support of the base over the oil wellhead even in uneven terrain. A cap device is mountable on the base and includes tangentially arranged ports designed to supply the interior of the cap with a fluid such as liquid nitrogen to cool and extinguish the flames. The cap may include a labyrinth tortuous path restrictor forcing escaping combustion products and other gases to follow a tortuous path to atmosphere to thereby cause the gases to lose energy and cool as they escape.

    摘要: Apparatus and method for determining the azimuth (heading), pitch and roll which include a magnetometer-type sensor providing signals measured in three axes relative to a reference frame, and coil elements wound around the magnetometer which selectively impose specific magnetic fields about the sensor. Three axes field components of the magnetic field are measured from the sensor with and without the selective energization of the magnetic coils and stored, from which the azimuth, pitch and roll are calculated. Furthermore, quadrant correction is applied such that a unique reading is produced for all angles through 360.degree. of azimuth, pitch or roll.
