Syllabus

<p>Patents; Novelty.</p> <p>An electro pneumatic regulating system, differing from an old one only in tlio substitution of one well-known form of motion for another, presents no novelty; and one who merely improves an existing regulating system by bodily substituting for the motor therein that of another system, which is also old, is not entitled to a Combination patent, as it involves no invention to make such substitution.
