Abstract
698,069. Automatic control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 12, 1948 [Nov. 14, 1947], No. 4222/52. Divided out of 698,035. Drawings to Specification. Class 38 (iv). The subject-matter of this Specification is included in Specification 698,035 but the claims relate to apparatus, responsive to rate-ofchange of pressure of a fluid medium, in which a flexible casing having an orifice therein moves the armature of an electromagnet to control an electric current which energizes the electromagnet to bias the armature in opposition to movement by the casing. Specification 698,032 also is referred to.
