Abstract

D R A W I N G
A TRANSPARENT ARTICLE HAVING REDUCED SOLAR RADIATION TRANSMITTANCE WHICH COMPRISES A BODY OF TRANSPARENT GLASSY SILICEOUS MATERIAL HAVING A SMOOTH CONTINUOUS SURFACE AND A CONTINUOUS FILM OF NICKEL OR NICKEL-BASE ALLOYS SPUTTER-COATED ON SAID CONTINUOUS SURFACE TO A THICKNESS OF FROM 50 TO 400 A. THE ARTICLE MAY INCLUDE A CONTINUOUS PROTECTIVE LAYER OF A SILICEOUS OR ALUMINUM OXIDE MATERIAL OVERLAYING THE CONTINUOUS FILM. THE SPUTTER-COATING TECHNIQUE PERMITS THE METAL FILM TO BE DEPOSITED WITH GREATER UNIFORMITY AND PURITY. THE RESULTING ARTICLE MAIN-IMIZES THE TRANSMITTANCE OF RADIATION IN THE INFRA-RED RANGE FOR ANY SELECTED TRANSMITTANCE OF VISIBLE LIGHT.
