ELECTRICALLY-CONDUCTIVE COMPOSITIONS AND METHODS OF USING THEM WITH PIPELINES
Minimum Federal Safety Standards for corrosion control on buried oil & gas pipelines stipulate that metallic pipes should be properly coated and have impressed-current cathodic protection (ICCP) systems in place to control the electrical potential field around a protected pipe. In certain examples described herein, electrically-conductive composites can be used and provide intrinsically-safe materials without the dielectric shielding issues of existing materials used with pipelines. As reacted by customary spray applications, the nanocomposite foams described herein are directly compatible with ICCP functionality wherever foam contacts the metallic pipe. Various compositions and their use with underground and/or above ground pipelines are described.

Expandable attachment for tumbler
An expandable attachment for securing a beverage container to a turner can include a linkage with arms, each of the arms having opposite ends, a grip pad pivotably attached to an end of each of the arms, the grip pad being configured to grip an interior surface of the beverage container, a threaded member, a base, the threaded member being rigidly secured to the base, and an end of an arm being pivotably attached to the base, another base, the threaded member being axially displaceable through the second base, and an end of the other arm being pivotably attached to the second base, and an adjustment wheel having threads therein engaged with threads of the threaded member. A method can include inserting an expandable attachment into a beverage container, and rotating a portion of the expandable attachment, thereby radially outwardly displacing grip pads of the expandable attachment.
DRUG ELUTING STENT AND METHOD OF USE OF THE SAME FOR ENABLING RESTORATION OF FUNCTIONAL ENDOTHELIAL CELL LAYERS
Drug eluting stents, methods of making, using, and verifying long-term stability of the drug eluting stents, and methods for predicting long term stent efficacy and patient safety after implantation of a drug eluting stent are disclosured. In one embodiment, a drug eluting stent may include a stent framework; a drug-containing layer; a drug embedded in the drug-containing layer; and a biocompatible base layer disposed over the stent framework and supporting the drug-containing layer. The drug-containing layer may have an uneven coating thickness. In addition or in alternative, the drug-containing layer may be configured to significantly dissolve/dissipate/disappear between 45 days and 60 days after stent implantation. Stents may reduce, minimize, or eliminate patient risks associated with the implantation of a stent, including, for example, restenosis, thrombosis, and/or MACE.

Apparatus for coating pipes
Apparatus for coating a pipe. The apparatus includes a first frame to be mounted on a pipe and a second frame rotatably mounted on the first frame. An induction heating coil comprised of electrical conductors is mounted on the apparatus. A coating applicator is mounted on the second frame and is arranged to apply coating onto a surface of the pipe on which the apparatus is mounted. The first frame, second frame and coating applicator are arranged such that when the apparatus is mounted on the pipe, the applicator is disposed to one side of the induction heating coil and able to apply coating to a surface of the pipe alongside the surface of the pipe underlying the induction heating coil. The first frame may be operable between an open state in which the frame may be placed over and removed from a pipe and a closed state in which the frame may capture a pipe thereby to mount the apparatus on the pipe.
