The upper surfaces of the slats are dull. The Specification as open to inspection under Sect. 91 (3) (a) states also that the frame may be fixed permanently to the lamp and that the slats which can be adjusted to, or fixed at, any angle, may be flat, curved, corrugated, or ribbed, or some may be flat and some corrugated or ribbed or curved. This subject-matter does not appear in the Specifiction as accepted.
