Michael L White: High incidence angle retroreflective material. Minnesota Mining and Manufacturing Company, C Alexander, D M Sell, R R Tamte, September 14, 1982: US04349598 (141 worldwide citation)

Retroreflective film, sheeting or the like having an array of light-reflecting right triangle prisms between a transparent surface layer and a backing layer. The opposing triangular end faces of adjacent prisms are spaced apart to provide internal reflection therefrom. The retroreflective material p ...

Peter A Howell: Glass bubbles of increased collapse strength. Minnesota Mining and Manufacturing Company, C Alexander, D M Sell, R R Tamte, July 5, 1983: US04391646 (103 worldwide citation)

Glass bubbles of increased collapse strength are prepared. The bubbles have an average particle density of 0.4 or more and are made of glass that consists essentially of SiO.sub.2 (60-90 weight-percent), alkali metal oxide (2-20 weight-percent), B.sub.2 O.sub.3 (1-30 weight-percent), sulfur (0.005 t ...

Dennis L Krueger, Daniel E Meyer: Bicomponent fibers and webs made therefrom. Minnesota Mining and Manufacturing Company, D M Sell, J A Smith, R R Tamte, October 15, 1985: US04547420 (96 worldwide citation)

Bicomponent fibers, and webs made therefrom, are taught in which one component of the fibers is a crystallizable material. When a web of the fibers is heated in a mold above the temperature at which crystallization occurs, the fibers tend to be set in the position they are held in the mold. A prefer ...

Chi F Tung, James C Coderre: Retroreflective sheeting. Minnesota Mining and Manufacturing Company, D M Sell, J A Smith, R R Tamte, April 16, 1985: US04511210 (55 worldwide citation)

New methods for making "embedded-lens" retroreflective sheeting, and new forms of such sheeting, are provided. The new methods involve embedding microspheres into a web by continuously presenting a mass of the microspheres against the moving web and heating the web so as to soften at least an exteri ...
