working hard bud?
Either for PYR or SH

Note this from the recent patent that was granted:

An apparatus and a process for the production at high capacity of high purity powders from a large diameter wire or rod using a combination of plasma torches and induction heating are disclosed. The process provides a superior productivity, by incorporating a more effective inductive preheating system. A mechanism is also included in the apparatus, which allows adjusting the position of the plasma torches and their angle of attack with respect to the wire, which has a direct effect on the mechanical and thermal energy transfer from the plasma plume to the wire, allowing a fine control over the particle size distribution as well as the production capacity. Furthermore, varying the induction frequency allows for the optimization of the temperature profile inside the wire, which can be directly correlated to the resulting mean particle size.

Here is the patent that was recently granted:

And from @ordos:

@ordosThis is very important patent. Actually there are several patents which relate to Pyrogenesis powder system, where essentially now any form of feedstock can be used: liquid, irregular, wire (single or double). The original one was the wire, which depended on the input material being in wire form. Now there is no dependency on the input material form factor, and therefore you can just load titanium or Inconel or ... in any form into the feeder and produce high quality spherical powders.

Could that have been the hold up in powder business in N.America? I'm privy to nothing,just a thought.
