Following up a thread in the history forum, I was niggled not to know when the positive displacement water meters were first invented.
The Nutating disc meter, popular in the US for utility metering, would appear to have been devised in or around 1850 but was the development from the earlier application of the principal as an engine and pump.
The rotary piston meter was, I believe, the invention of Sir William Siemens in 1851.
These two appear to be the only practical single element positive displacement meters about.
The Rotary Piston meter would seem to have been invented by a German only recently arrived in the UK to take up permanent residence. The term "British" thus refers to the patent and not the meter.
Sir William moved to England because he had discovered the benefits of the British Patent system compared to the German.
This set me to thinking that the patent system is a poor sabby thing long overdue for a significant overhaul.
For the poor struggling inventor, the costs of obtaining worldwide protection are prohibitive and the benefits scant. A patent is only as useful as the amount of money to defend it.
Some countries e.g. China, have a notorious disregard for patents and commonly reverse engineer designs of useful products.
How useful are patents? How useful should they be?
What should be done to provide better protection and rewards for inventors?
Is the British approach to patents better than the US with regard to the inventions of employees?
How long should patents last?
