    摘要： FIG. 1 is a left side view of our microtrencher blade, the right side being a mirror image thereof.
    FIG. 2 is a top front left side view thereof.
    FIG. 3 is a back top right view thereof.
    FIG. 4 is a front top right view thereof.
    FIG. 5 is an edge view thereof.
    FIG. 6 is an expanded fragmentary edge view of the blade as shown in the call-out of FIG. 5.
    FIG. 7 is an expanded fragmentary left side view of a tooth as shown in the call-out location of FIG. 1.
    FIG. 8 is a close up right side view thereof; and,
    FIG. 9 is an expanded fragmentary view of the call-out location shown in FIG. 2.
    The broken line elements are included for the purposes of illustrating portions of the microtrencher blade and form no part of the claimed design. The line indicated by alternating dot-dash is a boundary line, the interior of which does not form any part of the claimed design. FIGS. 1, 2 and 5 represent callout locations for the expanded fragmentary views shown therein, with the borders of the call-out locations shown by lines of alternating lengths. Lines included with thin weight and which do not extend to any adjacent line are provided to show contour.

    摘要： A method of handling pipe segments during makeup and breakout of a drill string. The method uses a hydraulic circuit, which provides fluid to a motor or motors for translating a drill pipe segment. The drill pipe segment is supported by a carriage, which places the segment next to a drill string for addition thereto. Hydraulic pressure within the circuit is monitored to determine if a pressure fluctuation exists. If so, the translation speed is adjusted by modifying the hydraulic fluid flow to the motors. Sensors may be utilized to determine whether or not the system is in a “transition zone” and therefore ready for pressure monitoring for makeup and breakout functions.

    摘要： A pipe assembly has a hollow inner member nested within a hollow outer member. A series of pipe assemblies are connected end-to-end to form a dual-member drill string useful in horizontal directional drilling operations. The drill string has mutually exclusive first and second fluid paths. Fluid seals, interposed between adjacent inner members of the string, isolate the first fluid path from the second fluid path. Compressed air is delivered into the first fluid path from above ground level, and routed to an underground boring tool. The expelled air and spoils are returned to above ground level by way of the second fluid path. One or more baffle elements are supported on the drill string adjacent the boring tool. The baffle elements are configured to prevent compressed air and spoils from flowing between the walls of the borehole and the drill string.

    摘要： FIG. 1 is a left side view of a pipe slitter, with a sharp edge of a slitter blade shown at the left side of the blade. A call-out in alternating long and short dash lines is provided to show the outer limits of FIG. 9.
    FIG. 2 is a right side view of thereof, with the sharp edge of the slitter blade shown at the right.
    FIG. 3 is a front view thereof, with the sharp edge facing out of the page.
    FIG. 4 is a back view thereof.
    FIG. 5 is a top view thereof.
    FIG. 6 is a bottom view thereof. In the bottom view, no claimed surface is visible.
    FIG. 7 is a top front left perspective view thereof.
    FIG. 8 is a top back right perspective view thereof; and,
    FIG. 9 is a left side view of the pipe slitter as shown in FIG. 1. The alternating long and short dashed line about the outside of the figure indicates the metes and bounds of the view, as shown in FIG. 1.
    The broken lines shown in the figures are for the purpose of illustrating portions of the pipe slitter and form no part of the claimed design. The line with alternating dot-dash is a boundary line denoting the edges of the claimed design.
    Lines which do not connect to adjacent lines and stippling are provided to show contour and are not a discrete surface feature.

    摘要： A pipe shuttle for moving a pipe segment from an operating position to a pipe box. The pipe shuttle has a pair of gripper arms flanking a cradle. The cradle has a spring-loaded pad that has a concave surface for holding a pipe segment. As the pipe shuttle moves from underneath a pipe box to near a cradle, rollers are positioned to engage a guide plate. When the shuttle is underneath the pipe box, the rollers engage the guide plate to keep the cradle open. When moved towards an operating position, the rollers no longer engage the guide plate and cause grippers to close on the pipe segment. The spring-loaded pad allows the pipe shuttle to be moved relative to the pipe segment when the pipe segment is in its operating position.
