PER CURIAM.
Upon rejection by the Patent Office of his application for a patent1 appellant filed an action in the District Court under 35 U.S.C. § 145, formerly Rev.Stat. § 4915, as amended. After a full hearing, followed by the court’s findings of fact and conclusions of law, the judgment appealed from was entered dismissing the complaint.

It is comprised of a fresnel type lens for collecting the light from approaching headlights, one or more photocells positioned behind the ^ens an the purpose of the photocells be-to convert the collected light into an. electrical signal, and^ a relay placed in the usual headlight circuit arrangement to dim the headlights in response to the signal.
The District Court found that the pri-or art includes the Gillespie patent2, showing the combination of a lens mounted on the front of an automobile to receive light from the headlights of an approaching vehicle, with a photoelectric cell positioned to receive the light collected by the lens and through the photocell operating circuit automatically dimming the headlights of the car on which the device is mounted. It found further that a fresnel type lens, among other uses in the prior art, had been used in combination with a photoelectric cell to measure light intensity.3
