Patent Number Title Of Patent Date Issued
4627287 Light-resistance tester for maintaining uniform temperature at surface of sample December 9, 1986
A light resistance tester for maintaining a uniform temperature of the surface of a sample being tested has a testing chamber, a light source mounted in the center of the testing chamber, an annular sample mounting frame positioned around the light source and rotatable around the light
4613235 Method and apparatus for measuring gloss which correlates well with visually estimated gloss September 23, 1986
A method and apparatus for measuring the gloss of a surface of a material by receiving light reflected from the surface and measuring the amount of light. Parallel light rays from a light source are directed against the surface the gloss of which is to be determined at an angle of incide
4544995 Apparatus for testing light fastness of a material October 1, 1985
An apparatus for testing light fastness of a material having a housing with a test chamber therein and two downwardly and outwardly inclined specimen supporting walls on opposite sides of the chamber and two rows of horizontally positioned equal intensity ultraviolet fluorescent lamps on
4519716 Device for testing combustability May 28, 1985
A device which simulates the burning of an elongated smoking product such as a cigarette, for testing the combustability of an article. The device includes a rod-shaped resistive heating element, the length and cross section of which are the same as those of the product whose burning
4232971 Integrating sphere type standard light source device November 11, 1980
An integrating sphere type standard light source has a spherical shell the inner surface of which is coated with a white coating having a high reflectivity. The shell has a light source aperture in the top thereof, a viewing aperture in the side thereof and a specimen exposure aperture i
4196611 Testing apparatus for determining abrasion resistance of a surface April 8, 1980
