A construction of ink dispensing roller is described in which a porous ink metering layer extends around a peripheral surface of a porous ink reservoir. A device including a complex article including a first component and a second component, the first and second components being one of individually replaceable and maintainable. By adding polymer to the composition based on polymer it is advantageously possible to obtain an even dispersion of the pigment so that a composition possessing outstanding opacity and still being processable under the form of films, so as to provide adequate mechanical properties, can be manufactured therefrom. In another embodiment, a plurality of rovings are arranged in clusters in the cable for influencing the bonding between the rovings and cable jacket. This results in faster convergence, lower protocol messages processed, and fewer route changes following a failure. In certain examples, a boost device may be used with a flame or plasma to provide additional energy to a flame or plasma to enhance desolvation, atomization, andor ionization.
