Syllabus

<p>1. Patents (§ 328*)—Invention—Electrical Transformer.</p> <p>The Hall patent, No. 829,780, for an electrical transformer, differing from prior structures only in the substitution of eccentric 1'or concentric coil mounting, is void for lack of invention.</p> <p>2. Patents (§ 16*)—Invention—Electrical Transformer.</p> <p>The work of a trained electrical engineer, who, following general directions given by his superior officer, made certain changes in an electrical transformer for the purpose and with the result of effecting econ-</p> <p>omies In construction, without departing from known principles, held not to have involved invention.</p> <p>[Ed. Note.—For other cases, see Patents, Cent. Dig. $ 15; Dee. Dig. § 16.*]</p> <p>3. Patents (§ 20*)—Invention—Electrical Transformer.</p> <p>The substitution in an electrical transformer of eccentric for concentric coil mounting did not involve patentable invention, in view of the fact that the general principles and practice of ventilating spaces in transformers wore well known, and the desirability of keeping the transformer coils dose together within the magnetic circuit for electrical advantages and of separating them outside the circuit for ventilating purposes.</p> <p>[Ed.
