摘要： A technique for providing a continuous underground tunnel between first and second spaced-apart points and for installing new cable, pipe or conduit is disclosed herein. This technique utilizes a boring device including means for boring through soil and a thrust conduit which pushes the boring device through the soil from a first starting point to a second end point as the device bores through the soil, whereby to form a tunnel between the two points. Thereafter, the cable to be installed within the tunnel is attached to the front end of the boring device and the latter is pulled back through the tunnel to its starting point by means of the thrust cable, thereby automatically pulling the new cable in place.

摘要： An assembly for transferring information to and/or from flexible sheet media in a highly advantageous curved configuration is disclosed. The sheet material includes a length and a width defining first and second opposing surfaces. The assembly includes support means for supporting the sheet the curved configuration across its width, having the first surface inwardly oriented with respect to the curved configuration. Thereafter, moving means moves the flexible sheet material so supported in a direction along a read/write path generally parallel to the sheet material length and transverse to the direction of curvature. A read/write arrangement is provided which is configured for reading and/or writing information across the width of the first surface of the sheet as the sheet is moved along the path in the curved configuration. In one feature, means is provided for rotationally moving the read/write arrangement in a predetermined way in the housing such that the read/write arrangement is in a confronting relationship with the first, inwardly oriented surface and cooperates with the movement provided by the sheet material moving means so as to cause the read/write arrangement to sequentially read information from and/or write information to the inwardly oriented, first surface of the sheet as the read/write arrangement traverses the width of the flexible sheet material while the latter is on the read/write path in the curved configuration. In another feature, a read and/or write operation may be performed on the second, outwardly oriented surface of the sheet material.

摘要： A device is described for use as part of a system in which a transmitter is moved through the ground while transmitting a signal that can be used to locate the transmitter. The device includes a receiver for receiving the signal to generate certain information about the position of the transmitter relative to the position of the device based on the signal. A processor establishes a current location of the transmitter and records the current location as one of a series of recorded locations of the transmitter based on the certain information and, at a time of recording the current location, electronically records a time stamp that designates at least the time at which the current location was recorded as part of the series of recorded locations of the transmitter.

摘要： A method is described for use in a region which contains at least first and second in-ground cables, each of which cables includes an electrically conductive component such that, when the first cable is driven at a locating signal frequency to emit a locating signal in an electromagnetic form, the locating signal can be coupled to the second cable in a way which causes the second cable to generate a false locating signal in electromagnetic form. The locating signal is received along with the false locating signal as well as receiving a reference signal which contains the locating signal frequency impressed thereon. The locating signal is distinguished from the false locating signal based on the locating signal frequency as contained by the reference signal.

摘要： A portable locator and method for establishing the location of the cable line in a region which includes at least one generally straight electrically conductive cable line extending across the region from which cable line a locating signal includes a first arrangement for measuring a local flux intensity of the locating signal at a first above ground point within the region with the portable locator in a particular orientation at the first above ground point. A second arrangement uses the local flux intensity to establish a cable line angular orientation which limits the possible directions to the cable line relative to the particular orientation of the portable locator at the above ground point. A third arrangement uses the measured local flux intensity to establish an actual direction of the cable line that is selected from the possible directions based on certain characteristics of the locating signal.

摘要： A drive train is used at least including an input shaft and an output shaft. A clutch member is rotatable by a clutch shaft about an axis of rotation. The clutch shaft is supported for lateral movement along the axis of rotation to move the clutch member to cooperate with the drive train at a first lateral position to cause the output shaft to turn and to move the clutch member to a second lateral position to disengage the output shaft from rotation of the input shaft. A permanent magnet is supported by one end of the clutch shaft and arranged for receiving an external magnetic biasing force along the axis of rotation to selectively move the clutch member between the first and second lateral positions. A traveling shaft can be used to support a selected gear for movement by the permanent magnet to implement transmission and reversing configurations.

摘要： A helicopter includes a rotor system having a rotor with an adjustable pitch that is controlled at least in part by a pilot using a collective control and which helicopter generates a Low RPM signal that is indicative of a threshold low rotational speed of the rotor. An actuator arrangement configured to move the collective control by exerting a force on the collective control such that the pilot is able to overcome the force but which otherwise moves the collective control from a current operational position toward a minimum pitch position. A control arrangement is configured for receiving the Low RPM signal and for responding to the Low RPM signal by activating the actuator arrangement for at least a predetermined period of time to apply the force to move the collective control from the current operational position to the minimum pitch position.
