Abstract: An article of footwear includes an adjustable element. The adjustable element includes a bladder that defines an interior void. A compressible component that is disposed within the interior void and is operable between an expanded state and a contracted state. The adjustable element also includes a lock strip including a first end anchored at a first location within the bladder and a second end disposed at an opposite end of the lock strip than the first end. A lock receives the lock strip and is operable between a locked state restricting movement of the lock strip relative to the bladder and an unlocked state permitting movement of the lock strip relative to the bladder.

Abstract: A method for determining the variations in the sulfur content of ultra-low sulfur diesel fuel when it is transported through a petroleum transportation system includes sampling fuels at various points during barge transport, pipeline transport and in terminaling operations. New procedures and special handling regiments are developed in view of how the sulfur content of ultra-low sulfur fuel may change when transported through the system in sequence and stored with other petroleum products.

Abstract: The present invention includes a reversible concrete cutting saw blade and one or two blade attachment plates having radial grooves formed in the blade engaging faces thereof, such that when the plates and blades are joined, radial passageways are formed between the plates and the blade. An inlet tube, communicating with a rotatable inner hub introduces cooling fluid into internal passage ways within the hub under positive flow conditions, thereby causing the fluid to flow through the hub to the radial passageways in the plates and then be centrifugally dispersed down the grooves along the surfaces of the blade.
