The coating gun and the first nozzle are arranged relative to each other such that gas discharged by the first nozzle is discharged toward the coating to alter a direction of the coating by the gas discharged by the first nozzle directly contacting the coating such that the coating would otherwise contact the cylinder bore of the second cylinder bank upon stopping discharge of the gas by the first nozzle. | 01-13-2011 |
| 20110048322 | Methods and Systems for Abrasive Cleaning and Barrier Coating/Sealing of Pipes - Methods and systems for abrasive cleaning, deburring pipes, providing barrier coatings and sealing leaks in existing pipes, in a single operation. A piping system can be cleaned in one pass set up by intermittent bursts of dry particulates that are forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from the effects of water corrosion, erosion corrosion and electrolysis, extending the life of piping systems such as copper, steel, lead, brass, cast iron piping and composite materials. Cleaning and barrier coating techniques described are efficient in pipes up to 2 inches in diameter, so that entire piping systems can be abrasive cleaned, coated and sealed. The leak sealant of at least approximately 4 mils thick can cover the cover insides of pipes. Piping systems can be returned to service within less than approximately 24 to 96 hours. The novel steps of cleaning out pipe systems can include generating pressurized gas into one end of a piping system having pipes, intermittently injecting bursts of abrasive particles into the pressurized gas into the end of the piping system, cleaning interior wall surfaces of the pipes with the intermittent bursts of the abrasive particles, reducing burrs, interior lips and excess seam joint edges in the interior wall surfaces of the pipes, and generating a vacuum suction at another end of the piping system to remove the abrasive particles and debris caused by the cleaning of the interior walls of the pipes. | 03-03-2011 |

| 20160120666 | Apparatus and Methods for Filling a Drug Eluting Medical Device Via Capillary Action - Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent. | 05-05-2016 |
