摘要： A downhole buried utility sensing and data transmission system for connection at the lower end of a drill string has sensors capable of detecting the existence of various different types of buried utilities and objects and making calculations as to the radial separation distance between the detected utilities and the drill head and transmitting data between the down hole drill head to the surface. The sensors respond to material properties used to construct the utility lines or the energy fields created by the operation of these lines (pipes and cables) or from the energy associated with transmission of the particular utility service, including sound energy resulting from fluid flow and electromagnetic energy from electric currents. The system can detect and distinguish the presence of ferromagnetic metallic objects including steel pipes and structures; non-metallic utility infrastructure including gas pipelines, concrete sewer lines, telecommunication lines, and cable systems outfitted with RF tracer lines and transmitters; energized AC and DC power cable systems; and determining the approximate range, relative azimuth, and elevation of the sensors relative to the detected utility or object. The system also supports automatic cessation of drilling operations by combining the warning information with microprocessor control of drill string rotation and thrust.

摘要： The described invention combines wireless transmission and reception technologies with athletic event timers to remove and reduce human and environmental factors that interfere with the athletic event timekeeping process for improvement of the process. The system controls and communicates the timing of a single athletic event between the timekeeping mechanism and the referee using at least one timing communicator with a transmitter and a channel selector. The transmitter is adapted to transmit a wireless electromagnetic radiation signal from outside the field of play to the field of play to a mobile field communicator having a receiver and channel selector also responsive to the channel selector. The mobile field communicator is adapted to be carried by the umpire or referee on the field of play and to receive the wireless signal from outside the field of play and emit an actuation signal in response thereto. The mobile field communicator and timing communicator channel selectors can be synchronized to produce the assignment of a unique address to allow the mobile field communicator and timing communicator to operate independently and securely without interference from other similar mobile field communicator and timing communicator devices in use within range of the system.

摘要： A wireless downhole electromagnetic data transmission system and method utilizes microprocessor controlled frequency synthesis for two-way communication between the surface and a downhole guided boring or drilling apparatus in the range of from 100 Hz to 100 KHz. A non-magnetic downhole probe unit connected between a drill motor or drill bit and the drill string contains data gathering and transmission components including accelerometers which measure the earth's gravity vector and fluxgate magnetometers which read the earth's magnetic field and serve as power line proximity sensors. The drill pipe acts as an electrical lossy, single conductor with the earth forming the electrical return path. Sensory data gathered by the downhole probe is encoded in digital format and impressed upon the drill string using frequency shift keying of the electromagnetic energy waves and is picked off at the surface by a signal receiver-demodulator and message processor unit. The surface unit instructs the downhole probe to transmit multiple frequencies and selects one or more frequencies with the most favorable signal-to-noise ratio(s) in response to local conditions to maximize the transmission distance at a selective frequency band range and given transmitter power level and baud rate. The received signal is filtered, demodulated, processed and displayed at the surface and gravity and magnetic field vectors are combined with the created hole length to calculate x, y, and z hole coordinates and derive hole position vectors.

摘要： A textile yarn winding apparatus for winding a continuously produced yarn, said apparatus being of the type having spindles carrying two axially aligned flanged bobbins and a yarn guide which is reciprocated along the length of one or other of the flanged bobbins so as to lay yarn wherein the yarn guide may be moved from its path along the length of one bobbin to a corresponding path along the length of a second bobbin when it is desired to transfer the winding from one bobbin to another, whereby the take-up of the yarn continues without interruption, the yarn being led from the surface of the completed bobbin over the adjacent flanges of the completed and empty bobbins to the barrel of the empty bobbin thus connecting the two. Yarn severing means is arranged to engage that part of the connecting yarn which extends at an angle between the flange and barrel of the empty bobbin so as to sever it but not before the yarn guide has been driven in the direction of the flange of the empty bobbin adjacent the completed bobbin. This ensures that when transferring yarn from a completed bobbin to an empty bobbin, the tail of the yarn left on the empty bobbin after severing is kept to a manageable length and the initial winding of the yarn on the empty bobbin is tightly and securely wrapped around the barrel thereof.

摘要： Thermoplastic yarn is texturized by the known method of forwarding it in a heated condition to a crimping zone at the entrance of a stuffer chamber (7) so as to form a plug (8) of crimped yarn within the chamber and withdrawing the yarn from the other end of the plug at a speed which is related to the input speed. The improvement comprises deriving signals from the speed of the yarn plug (8) in the stuffer chamber (7) by means of a sensing wheel (11) which drives a gapped monitoring disc (13). The disc (13) operates to intercept a beam of light from a source (14) which is directed on to a photo-sensor (15). The output of the photo-sensor is supplied to an electrical controller (36) which measures the time during which light is received for each gap in the disc (13) to provide a measure of the speed of the yarn plug. The resultant signals are used to control the temperature of the yarn passing to the crimping zone in such a way as to maintain the speed and hence the quality of the bulk yarn substantially constant. For this purpose, the signals from the controller (36) are fed to a heater controller (28) to adjust the current to a heating element (5) in a chamber (4) through which steam passes before feeding the yarn (1) through a jet passage (2) leading to the chamber (7).
