This book contains inventions and my great ideas over a period of 40 years. Now, that I had my 83rd birthday, it came to my mind, that I can't take all of these inventions and great ideas with me on my last day. Since I wrote down all these inventions and great ideas, I decided to put them all in a book with the hope that someone will be able to make a good improvement on an invention and develop it in to a personal gain. In addition I hope that peoplde like you just by reading this book are inspired enough to come up with an invention of their own.
