Tipi Eisberg, a contributor to Martin G's Really Magazine, normally reviews the more intriguing American patent applications but has recently started selecting some and showing only the drawings, leaving readers to guess what purpose the devices are intended to serve. That this is not always easy may be judged by looking at the three currently selected (Week 08); you can find the answers by clicking on the drawings, but I will spoil these puzzles by revealing that these patents cover, respectively, an electronic device for training animals, a helmet for wearing in the water which enables you to squirt stuff at other swimmers, and a method of gas stunning chickens before slaughtering them.
But the simplest inventions are always the best, and my current favourite is An Apparatus for Improving the Taste of Beverages. Martin is greatly taken by the idea, as everyone may well be, of turning a bottle of plonk into something really good by putting a magnet in it.
One reason why I like this one is that although it is indeed very simple, its description runs to one sentence of 399 words; I like long sentences. The longest one I have ever posted was a mere 164, but that was in 2004, when I was young.
[Unaccountably, I missed Disposable protector for engaging a clogged toilet and containing splashes in the clogged toilet occurring during unclogging of the clogged toilet by a plunger when Martin published it at the end of 2007.]
