    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 robotic arm includes at least two two-joint modules and at least a first link. Each two-joint module includes a housing, a pair of hollow rotary actuator assemblies and a pair of motor drives. Each actuator assembly has an axis and a hollow shaft and the axes are arranged at an angle to each other. The pair of hollow rotary actuator assemblies are arranged such that a back end of the actuator assemblies is inside the housing and a front end of the actuator assemblies extends outwardly of the housing, and attached to the housing such that cables can be fed from the outside of one of the actuator assemblies to the inside thereof and to the inside of the other actuator assemblies to the outside thereof. The pair of motor drives are operably attached to the actuator assemblies and the motor drives are outside the housing.

    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.
