Abstract: An apparatus for performing ultrasonic evaluation of a portion of a pipe includes a frame assembly and a plurality of ultrasonic sensors disposed in the frame assembly. The frame assembly includes a frame which is structured to cooperatively engage an outer surface of the pipe. The frame has a curved surface which is curved about an axis which, when the frame is engaged with the pipe, generally coincides with the central longitudinal axis of the pipe. The curved surface is generally defined by a radius which is generally equal to an outer radius of the pipe. The plurality of ultrasonic sensors are disposed in the frame assembly a fixed distance from the curved surface.

Abstract: An apparatus providing rotational power to the crank shaft actuating the lowering and raising of legs for supporting a load bearing vehicle. The apparatus includes a means for providing rotational force to the crank shaft comprising a battery powered motorized drill having a drive shaft having a plurality of rotational directions, and a motor housing. Also included is a crank shaft coupler adapted for removable attachment to the crank shaft, comprising an adaptor end having a non-round cross-section, and an attachment end defining a cavity snugly accepting the crank shaft and including a pair of apertures aligned with a transverse bore through the crank shaft through which a lock pin is inserted.

Abstract: An alignment guide and remotely operated latch mechanism for use in coupling a towing dolly of a two trailer rig, the towing dolly being connected to a first trailer of the two trailer rig and used to pull a second trailer of the two trailer rig behind the first trailer, the alignment guide facilitating coaxial alignment of the towing dolly with the first trailer by pulling the first trailer and towing dolly forward with a tractor, and the alignment guide further facilitating the coaxially aligned first trailer and towing dolly to be backed up together for hitching the towing dolly to the second trailer.
