Abstract: A production tubing joint is disclosed for a well comprising a barrel forming an upper tubing section and connected to the tubing hanger, a tubing connector within the barrel having a lower end connected to a lower tubing section of the production tubing string, a lower locking means having a first lower lock component secured to the barrel and a second lower lock component secured to the tubing connector and selectively engageable with the first lower lock component for suspending the tubing connector and the lower tubing section from the barrel, an adapter bar for connection to a rod string, and an upper locking means having a first upper lock component secured to the tubing connector and a second upper lock component secured to the adapter bar and selectively engageable with the first upper lock component.

Abstract: The present invention relates to a thin impermeable top coat on a thermal barrier coating for a metal part, such as a turbine blade, wherein the composite thin top coat is porous, inert, non-sacrificial, less permeable ceramic layer that eliminates the infiltration of environmental contaminants into the thermal barrier coating during operation of the metal part, thereby extending the life of the underlying thermal barrier coating and metal part thereunder.

Abstract: A foot-operated control for controlling both speed and steering of a trolling motor for a watercraft, the foot-operated control in communication with the trolling motor and comprising a base and a foot interface. The foot interface is pivotally connected at a generally central point by a pivot to the base, the pivot separating and defining a first end and second end of the foot interface, such that depressing the first end directs the trolling motor to steer the watercraft to the right and depressing the second end directs the trolling motor to steer the watercraft to the left.
