摘要： Cutting elements may be used to degrade hard surfaces in roadway surface milling, earthworking, mining, or other in situ disintegration processes. A plurality of such cutting elements may be disposed on a movable base and thereby brought into engagement with a degradable surface. Groupings of the plurality of cutting elements may comprise unique cutting surface geometries. Various groupings may be arranged on the movable base such that the degradable surface forms a cross-sectional topography resembling a waveform comprising truncated peaks.

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： In one aspect of the present invention a force balanced drill bit may comprise a bit body comprising a plurality of fixed blades, each blade comprising cutters defining a cutter profile. Junk slots may be disposed between the blades and define the blade boundaries. The blade boundaries may be spaced apart sufficiently to achieve force balance.In another aspect of the present invention a method of designing a downhole fixed bladed bit comprises the steps of modeling a fixed bladed bit by inputting blade and cutter parameters into a computer program, performing a force balance on the modeled fixed bladed bit, and modifying at least one blade parameter to adjust the force balance. The parameters for modeling a fixed bladed bit include cutter placement on a plurality of blades integrally formed in a bit body and a position for each blade.
