    Abstract: A radio frequency (RF) coaxial transmission line to be positioned within a wellbore in a subterranean formation may include a series of coaxial sections coupled together in end-to-end relation. Each coaxial section may include an inner conductor, a dual-wall outer conductor surrounding the inner conductor, and a dielectric therebetween. Each of the dual-wall outer conductors may include an outer wall and an inner wall spaced apart therefrom defining a fluid passageway. Each coaxial section may further include a threaded endpiece coupled to each opposing end of the dual-wall outer conductor and having threads to define an overlapping mechanical threaded joint and an electrical joint with an adjacent threaded endpiece.

    Abstract: A vehicle cargo bed extender adapted to be used in conjunction with a vehicle having a cargo bed. The present invention includes a pair of sidewalls spaced from one another, a center wall extending between the pair of sidewalls, the pair of sidewalls and the center wall cooperating to define a bed extender having an open end. Each of the pair of sidewalls of the bed extender include a pivot assembly disposed between the sidewall of the bed extender and a sidewall of the cargo bed and including a pivot axis defined by a post, and a slot adapted to slidingly accept the post. The post and the slot cooperate to facilitate both pivotal movement of the bed extender and rectilinear longitudinal movement of the bed extender relative to the cargo bed of the vehicle.
