Abstract
506,637. Colour lighting. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCH LABORATORIUM DE SPAARNESTADHAARLEM. Sept. 29, 1937, Nos. 26371, 26372, and 26373. Convention dates, Sept. 29, 1936, Jan. 19, 1937, and March 9, 1937. [Class 75 (iv)] [Also in Groups XX and IV] In producing heightened colour effects, light from the object reaching the eye or photographic material consists only of rays of wavelengths approximating to 4500, 5500, and 6500 A mixed in proportions to yield approximately white light, the intermediate wavelengths being eliminated. The Specification as open to inspection under Sect. 91 comprises also the use of a mercury vapour tube giving green or blue light, in combination with the light of street or house lamps. This subject-matter does not appear in the Specification as accepted.
