Abstract: A dowel sleeve has a tubular body with a mounting assembly at one end for releasable connection to a construction plate, and a leg support engagable at the other end for adjustable support. The construction plate has spaced non-circular holes. A first flange of the mounting assembly has a complementary profile, of smaller dimensions, to the non-circular holes, while a second flange has a similar profile, of larger dimensions, with its major-axis non-aligned with the major-axis of the first flange. The first flange is inserted through one of the non-circular holes, and the tubular body is rotated so the first and second flanges engage opposed faces of the construction plate.The leg support has a spigot engagable in the tubular body, the exterior of which is engaged by an abutment face. The effective length of the support leg is adjustable by selectively detaching one or more leg member segments, each provided with a disc-like base member.

Abstract: Location determination is performed using a transmitter including an elongated generally planar loop antenna defining an elongation axis. The elongation axis is positioned along at least a portion of a path. A magnetic field is then generated which approximates a dipole field. Certain characteristics of the magnetic field are then determined at a receiving position radially displaced from the antenna elongation axis. Using the determined certain characteristics, at least one orientation parameter is established which characterizes a positional relationship between the receiving position and the antenna on the path. The magnetic field may be transmitted as a monotone single phase signal. The orientation parameter may be a radial offset and/or an angular orientation between the receiving position and the antenna on the path. The antenna of the transmitter may be inserted into a first borehole to transmit the magnetic field to a receiver inserted into a second borehole.

Abstract: An above ground locator includes an apparatus for determining the strength of the locating signal at a selected point relative to the boring tool. The apparatus includes an antenna arrangement configured for measuring the strength of the locating signal at the selected point along first and second orthogonally opposed receiving axes to produce first and second received signals. A phase shifting arrangement phase shifts the first and second received signals in a predetermined way to generate first and second phase shifted signals, respectively. Thereafter, a summing arrangement adds the first and second phase shifted received signals to generate an output signal which is a vector sum of the first and second received signals. In one feature, third and fourth signals derived from the first and second signals are used to eliminate balance point ambiguity which is present using the first and second signals alone. In another feature, signals corresponding to first, second, third and fourth axes are compared in a way which confines the possible locations of an above ground point to one particular type of region out of a plurality of different types of regions. Tracking of the boring tool may be accomplished in a number of described ways since the regions occur in a specific sequence along the intended path with respect to the location of the boring tool.

Abstract: A boring tool is moved through the ground in a region which includes at least one electrically conductive in-ground line and which is subject to static magnetic fields including the magnetic field of the earth. Tracking a positional relationship between the boring tool and the line, as well as a directional heading of the boring tool within the region are provided by: (i) generating a time varying magnetic field from the line; (ii) at the boring tool, detecting a composite magnetic signal which includes one component affected by the static magnetic fields and another component affected by the time varying magnetic field such that the static magnetic field component varies as a function of the directional heading and the time varying component varies as a function of the positional relationship; and (iii) processing the composite magnetic signal to separate the static magnetic field component and the time varying magnetic field component from the composite magnetic signal for use in determining the directional heading and the positional relationship. In one feature, the static magnetic field component is used to determine the directional heading of the boring tool and the time varying magnetic field component is used to determine the positional relationship.

Abstract: Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.

Abstract: 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.

Abstract: 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.
