Where can I get a hold of that British patent? Sounds interesting! Was it followed up with a US patent?

Funny you should mention, I was looking at the British patent
yesterday, as it was on top of a pile of old Threshold paper.

The British patent was simply a foreign issue of U.S. patent
#3,995,228. I don't know whether hawksford might have been
inspired by it or not, but it does share a very similar topology,
and it's function is that of increasing the bias voltage against
increasing drops from the Bases of the drivers to the output.

Here is a figure from the patent, whose function is better
illuminated by the knowledge that the diodes are low forward
voltage types, Germanium or Schottky.

:cool:
