摘要： A cable terminal and clamp system particularly suited for use in an x-ray tube environment. The cable terminal and clamp system includes a cable socket having cable and terminal ports, each of which defines an axis. The cable terminal and clamp system includes a cable clamp that receives at least a portion of the cable socket. The cable clamp and cable socket are configured so that motion of the cable socket, relative to the cable clamp, along the axis defined by the terminal port is unimpaired, while motion of the cable socket, relative to the cable clamp, along the axis defined by the cable port is precluded. A spring interposed between the cable socket and cable clamp biases the cable socket away from the cable clamp along the axis defined by the terminal port. The cable terminal and clamp system thus accommodates thermal expansion of the terminal, while retaining the terminal in an associated receptacle and maintaining alignment of the cable clamp and cable socket.

摘要： An anti-whirl rotary drag bit including one or more cutters, wear knots or other support structures disposed on the flank of a bit profile in a normally cutter-devoid region of the profile adjacent the gage of the bit in the circumferential segment of the gage used as a bearing zone for the bit to ride against the side of the bore hole. Such flank cutters or other structures reduce wear of the bearing zone but, due to their placement, do not come into play except under certain drilling situations such as reaming or high rates of penetration wherein whirl tendencies resulting from cutting forces are not as pronounced.

摘要： A rotary drag bit including exterior features to control the depth of cut by cutters mounted thereon, so as to control the volume of formation material cut per bit rotation as well as the torque experienced by the bit and an associated bottomhole assembly. The exterior features preferably precede, taken in the direction of bit rotation, cutters with which they are associated, and provide sufficient bearing area so as to support the bit against the bottom of the borehole under weight on bit without exceeding the compressive strength of the formation rock. The exterior features may be oriented and configured to function optimally at a predicted rate of penetration, or range of rates, at which the bit may be operated, such rate or rates being further optionally maximized in softer formations in light of the ability of the bit to hydraulically clear a maximum volume of formation cuttings to prevent so-called bit balling.

摘要： This invention discloses a drilling structure having a body defining at least one primary channel and at least one secondary channel therein to initiate and maintain recirculation of an amount of drilling fluid back through the secondary channel to maintain positive, independent flow of drilling fluid through each primary channel of the drilling structure. The recirculation of drilling fluid is encouraged by providing a recirculation passageway in fluid communication with the primary channel defined by a portion of the body of the drilling structure that separates positively flowing drilling mud from drilling mud that is being recirculated. The recirculation action of the fluid in the recirculating loop may be fed and brought about by entrainment of the fluid with jetted fluid from an adjacent nozzle. The portion of the body may form a partition, such as a wall extending at least partially between the sides of the primary channel, a fin positioned within the primary channel that generally radially extends from the centerline of the drilling structure, or an internal channel or feeder that extracts fluid from the annulus at a point of low velocity and reintroduces it at a point of higher velocity proximate the bit face, usually near a nozzle. In addition, portions of the drilling structure are streamlined to further encourage positive, stable flow of fluid and formation cuttings generated from an associated cutting structure.

摘要： A system for securely maintaining a high voltage cable within an electrical device, such as an x-ray tube, is disclosed. The system is useful for ensuring a close fit between an x-ray tube cathode insulator and the high voltage cable assembly disposed therein, thereby reducing the chances for damaging electrical arcing to occur. A high voltage cable assembly and clamp body generally comprise the system. The high voltage cable comprises two sections disposed at a right angle with respect to one another. One section defines a cavity for receiving a plunger/spring assembly housed within the clamp body. The plunger/spring assembly compresses and expands in response to the thermal expansion and contraction of the high voltage cable assembly during tube operation. A calibration window and adjustment screws are provided with the clamp body to enable a technician to readily determine and adjust the level of compressive force imparted by the system.
