PER CURIAM.
The finding of the Secretary of Health, Education, and Welfare that Appellant had no period of disability under 42 U.S. C.A. § 416(i) — so as to entitle Appellant to disability insurance benefits under 42 U.S.C.A. § 423 — is supported by substantial evidence, 42 U.S.C.A. § 405 (g), and consequently the District Court did not err in granting summary judgment for the Secretary. Affirmed.
