Important things 3.

Now, the "Pictorial Handbook of Technical Devices" by Paul Grafstein and Otto B. Schwarz. 604 pages, published 1978, mine since approx. 1994. I will quote from the back cover "To the practical person, a properly drawn sketch, cutaway diagram, or photograph is worth many pages of description." I feel that to be very, very true. The book is set up like so: left-hand page- list of devices with name and description, right-hand page- photo/illo of devices with letter/number. I love this book. Like the previous books I mentioned in this series of posts, it too is out of print. The book is divided into ten main sections (with subsections in each): Machine Technology, Magnetics and Electronics, Light and Optics, Fluid Technology, Industrial Processes, Power Generation, Structural Engineering, Comfort Heating and Cooling, Transducers, and Metrology. My only major complaint is the scarcity of hinges/joints. There is one page of "Hinges" and one of "Angular Couplings and Universal Joints". Otherwise, this book is a wonderful asset to anyone interested in mechanical devices of many sizes and types. If anyone is aware of a dedicated book or website about hinges/joints, especially recessed or hidden ones, please email me: deadtech1(AT)yahoo(DOT)com
