There have been many research activities into the use of electrical arc discharge to produce metal nanopowders. An electrical arc discharge is an electrical breakdown of a gas between two conducted electrodes connected to typical dc welding power supplies, operated at currents up to 120 A. The arc...
As an alternative, or in combination therewith, it is possible to make the reinforcement element of a metal material in particular of a bendable wire or profile material. It is also possible to form the reinforcement element of an alt least locally thermo-deformable material, in particular a ...
FIG. 10 shows the sketch of a preferred embodiment of a channel means for discharging breathing gas. The breathing gas path defined in this case extends through a passage opening53in a first intermediate chamber54, which communicates with the atmosphere via a gap portion55. A plurality of web...
