I found the patents for two of my Grandad’s (Frank Fox) inventions. The first one is for a device similar to the Rubik’s cube, but my Grandad filed for the patent in 1970, quite a few years before Rubik.
This patent can be found here: GB1344259A – Spherical 2×2x2
The second was for “The Box”, which was effectively a very powerful graphic equaliser, which measured the volume and depth of sound. I can’t really do it justice from my poor explanation of it. Granada Studios purchased a few to help them get the sound levels correct when recording Coronation Street.
Here’s his patent: GB2134687A – The Box
