Plating accelerator is applied selectively to a substantially-unfilled wide (e.g., low-aspect-ratio feature cavity. Then, plating of metal is conducted to fill the wide feature cavity and to form an embossed structure in which the height of a wide-feature metal protrusion over the metal-filled wide-feature cavity is higher than the height of metal over field regions. Most of the overburden metal is removed using non-contact techniques, such as chemical wet etching. Metal above the wide feature cavity protects the metal-filled wide-feature interconnect against dishing, and improved planarization techniques avoid erosion of the metal interconnect and dielectric insulating layer. In some embodiments, plating of metal onto a substrate is conducted to fill narrow (e.g., high-aspect-ratio feature cavities) in the dielectric layer before selective application of plating accelerator and filling of the wide feature cavity.

The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

A method and apparatus for providing metal or non-metal vessels, including straight and curved pipes and various pipe connections, such as T's, elbows, swages, etc., and pressure containing vessels such as tanks, with an external composite lining of a webbing of biaxial or triaxial weave preferably composed of fiberglass which is pre-impregnated with a high temperature heat curable polymer composition capable of being heat cured at a temperature range of from about 275° F. to about 375° F. The vessel is prepared for bonding by abrasive cleaning and by solvent cleaning. Metal imperfections are then filled with an epoxy. A small amount a quick setting epoxy is employed to attach one end of the web to the external surface of the vessel in oriented position for wrapping of the web in intimate surface-to-surface contact with the vessel. During wrapping only enough tension is applied to the pre-impregnated webbing to eliminate any wrinkles. The number of layers of the impregnated webbing will be determined by the safe pressure containing capability of the pipe or vessel and its composite lining. An external heating element is then placed about the wrapping of pre-impregnated webbing material so as to be in substantially intimate relation therewith and is energized to apply sufficient heat for a sufficient period of time to completely cure the epoxy surface filler and to cure the polymer resin components of the pre-impregnated woven wrappings of webbing.

A system for capturing displaced fluid or pumping fluid through tubulars being run into or out of the wellbore is described. Embodiments are supported by a traveling block and top drive unit with telescoping features to rapidly seal over a tubular to connect the tubular to a mud system. Alternative sealing arrangements for sealing inside the tubular connection are also disclosed. These alternate sealing arrangements also provide flow areas larger than the tubular body since no portion of these arrangements enter the tubular body. All of the sealing arrangements provide a biased area whereby any internal pressure in the invention forces the seals into more intimate contact with their mating seal surfaces. A mudsaver valve having a large flow capacity is described to keep fluid from spilling when the apparatus is removed from the tubular. This mudsaver valve also provides for pumping of fluid into the tubular or flow of fluid from the tubular to the mud system prior to removing the apparatus from the tubular. In these embodiments, the apparatus can be placed in threaded sealing contact with the tubular and can incorporate a safety valve that can be manually closed in the event of a well kick. In another embodiment, a singular control input accomplishes operation of the apparatus to extend or retract the telescoping feature. Also illustrated is a drain valve that provides a method of completely removing all fluid pressure from within the apparatus prior to removing the apparatus from the tubular. The drain system also provides a means of disposing of the excess fluid away from the rig floor where spillage is a danger to the personnel or environment. The drain system can also be connected to a scavenger system that is intended as a vacuum system for removal of spillage. Connection to this system eliminates all possible spillage and completely removes fluids from the tubular handling area.
