摘要： In one aspect of the present invention, a system assembly for identifying a ferrous material comprises a plurality of magnetometers spaced at varying distances from a ferrous material. Each of the plurality of magnetometers may comprise a sensor reading of a magnitude of an absolute magnetic field, which comprises a magnetic field created by the ferrous material and an ambient magnetic field. One of the plurality of magnetometers may be designated as a primary magnetometer. A distance to the ferrous material from the primary magnetometer may be determined by forming a ratio of the differences in the sensor reading of the primary magnetometer and the sensor readings of the other magnetometers set equal to a ratio of the differences in the distance to the ferrous material from the primary magnetometer inversely cubed and the distances to the ferrous material from the other magnetometers inversely cubed. The system assembly may also comprise a picture taking device that may provide an image of a surface viewable from above the ferrous material and a global positioning system device that may provide a map of a geographical region.

摘要： An apparatus for regulating a flow of pavement rejuvenation materials for deposit on a roadway is disclosed in one aspect of the invention as including a first channel is supported by a pavement recycling machine and is in communication with a supply of pavement rejuvenation materials; a second channel slideably coupled to the first channel, the pavement rejuvenation materials adapted to flow through the first and second channels; and a hardened tip coupled to the second channel. The apparatus may also have a seat coupled to one of the channels; and a blocking element coupled to the other of the channels. Upon sliding the first channel with respect to the second channel, the blocking element contacts the seat, thereby impeding the flow of pavement rejuvenation materials flowing through the channels.

摘要： Pick tool assemblies for use with formation degradation machines, such as road milling, mining, trenching or drilling machines, may be disposed on rotatable drums, wheels, continuous chains, drill bits or the like and brought into engagement with such formations as rock, asphalt, coal or concrete to break up or otherwise degrade the formations. Such pick tool assemblies may comprise a shank comprising a forward end and a rearward end wherein the rearward end may be formed for retention in a bore of a block attached to a driving mechanism and the forward end may comprise a body detachably and nonrotatably fastened thereto. Further, an impact tip may be bonded opposite the rearward end.

摘要： An object detection system may be capable of sensing a buried object and providing an estimate of the object's depth. The object detection system may comprise a signal generator transmitting one or more signals. At least one of the signals may be directed toward the buried object and reflected off of the object back to the system. At least one of the signals may be transmitted along a variable length path. A correlator may then receive the signals and determine an offset between their arrival times at the correlator. The variable length path may then be adjusted over a range which includes a minimum offset indicating a distance to the object.
