Title: Optical flaw detection for photomasks - by angularly adjustable parallel light beam on side opposite to microscope
Inventor: WALTHER ALBERT ING GRAD
IPC: G03F1/00
Filed: 1978-11-07
Abstract: Method for the optical check of photomasks, consisting of glass plates with one-sided opaque structures, by a microscope, is based on directing a parallel beam of light against the underside while the microscope is focussed on a major plane of the mask. The angle of the incident light beam is varied in the horizontal and vertical plane to prevent its perpendicular incidence on the edges of the opaque structures. These edges therefore have little brilliance under the microscope but any scratched or foreign particles adhering to the photomask after usage are clearly marked by a strong contrast. This is a low-cost method of finding and localising defects in photomasks.

Title: Childproof bottle closure - requiring displacement of safety ring before bead engagement can be broken
Inventor: HEINLEIN HANS
IPC: B65D50/04
Filed: 1979-08-02
Abstract: A childproof closure for bottles includes a screw cap which seals the bottle and is normally held captive by its internal bottom bead snapping over an external bead on the bottle neck. The two cannot be sepd. by force because a safety ring is suspended from a step on the cap periphery. The two-part safety ring must be pushed downward against the force of its attachment to the cap step until it clears the bead on the bottle. The cap can then be unscrewed. This closure consists of few parts and can be produced at low cost. It retains its safety features even if used over long-periods.
