art or science to which it appertains, or with which it is most nearly

connected, to make, construct, compound, and use the same; and in case

of a machine, he shall explain the principle thereof and the best mode

in which he has contemplated applying that principle, so as to

out and distinctly claim that part, improvement or combination which he

claims as his invention or discovery. The specification and claim shall
