Isn't that proprietary T-max technology ?
This was described by Herb Wilgus in a paper in an engineering jorunal in the 70s. I am not a member, and so I cannot read the journal but this was also described in other articles and patents. There are 3 version in use at EK AFAIK. It is virtually essential that high speed mixing take place in order to make any modern emulsion, but it is not essential to making a T-Grain emulsion.
