I think I remember that patent, it annoyed me so much at the time. I
believe it was
the "ballbarrow" where the conventional wheel was replaced with a ball
diameter. The claim was to do with larger load area when used on soft
while having a small load area and therefore less drag when on harder
I believe this was patented by Dyson, of vacuum cleaner fame (I lived
a few miles from his factory at the time).
