    Abstract: A tooling arm includes a housing, a drive system, a lead screw and nut assembly, and a scoop assembly. The lead screw and nut assembly is operably connected to the drive system such that rotation of the nut drives the lead screw upwardly and downwardly relative to the housing. The scoop assembly is operably connected to the lead screw. The scoop assembly has an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position.

    Abstract: A crack arrestor apparatus and method for making same by applying layers of a composite material of non-metallic fibers and resin around a length of pipe; the fibers generally aligned with the pipe circumference. The applied layers have a thicker portion in the middle and a thinner portion on the ends. Part of the pipe covered by the thicker portion is then yielded by application of radial force past the elastic limit of the pipe, thereby creating circumferential tension on the composite. At least a portion of the composite remains in circumferential tension upon release of the radial force. The residual stresses in the yielded metal pipe assist to arrest crack propagation. Thereby, the process to arrest a crack in a metal pipe includes maintaining circumferential tension in a composite residing around the pipe while maintaining compressive circumferential residual stress on the metal pipe covered by the composite.

    Abstract: A mobile vehicle includes a platform, a pair of track assemblies and a pair of wheel assemblies. The pair of track assemblies is attached to opposing sides of the platform. The pair of wheel assemblies is attached to opposing sides of the platform. Each wheel assembly has at least a first and second wheel and a track-wheel interchange mechanism operably connected to the first and second wheel. The track-wheel interchange mechanism rotatably moves the first and second wheel from wheel mode wherein the wheels drive the mobile vehicle to a track mode wherein the track assemblies drive the mobile vehicle.

    Abstract translation: 一种防裂器装置及其制造方法，其特征在于，通过在一定长度的管子上施加非金属纤维和树脂的复合材料层; 纤维通常与管圆周对齐。 所施加的层在中间具有较厚部分，并且在端部上具有较薄部分。 然后由较厚部分覆盖的管的一部分通过施加径向力超过管的弹性极限而产生，从而在复合材料上产生周向张力。 当释放径向力时，复合材料的至少一部分保持圆周张力。 屈服金属管中的残余应力有助于阻止裂纹扩展。 因此，在金属管中阻止裂纹的过程包括保持在管周围的复合材料中的周向张力，同时保持由复合材料覆盖的金属管上的压缩圆周残余应力。

    Abstract: The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.
