Apparatus associated with the production of hydrocarbons comprising a joint assembly comprising a main body portion having primary and secondary fluid flow paths, wherein the main body portion is attached to a load sleeve assembly at one end and a torque sleeve assembly at the opposite end. An address for the memory cell is determined. The spherical shells are made from glass and therefore acoustically transparent and in combination with the cores are statically stiffer than the surrounding matrix material. Each node executes a predetermined algorithm for selecting entries in the reachability application routing table to be written to the kernel routing table. The method enables the PC to set up, in response to the message, a proxy client for communicating with a port of the upgrade indicated by the port number.
