Welsbach Light Co. v. New York Chemical Refining Co.

I .ACOMBE, Circuit Judge. The Helouis process for treatment of lime crayons, which is relied upon as an anticipation in this case, seems quite different in object and result from that of the patent. Within the range of equivalents indicated by Judge Townsend in the Sunlight Incandescent Gas Lamp Case. 87 Fed. 221, the process of defendant is an infringement. Preliminary injunction accordingly.
