20090021831, Jan 22, 2009

Filed:

Jul 16, 2007

Appl. No.:

11/778216

Inventors:

Bradley R. Ray - Woodbury MN, US
Joy L. Manske - Menomonie WI, US
Rodney A. Ough - Woodbury MN, US

International Classification:

G02B 5/124
G02B 1/10

US Classification:

359530

Abstract:

A prismatic retroreflective article and a method for making same. The retroreflective article can include a transparent polymeric body portion, an optical layer coupled to the body portion, and an image layer coupled to the body portion opposite the optical layer. The image layer can define imaged portions and non-imaged portions of the prismatic retroreflective article. The image layer can include cross-links formed between a polymer resin having hydroxyl functional groups and a cross-linking agent having isocyanate functional groups. The image layer can have a percent elongation of at least 80 percent and less than 200 percent. The method can include printing or coating an image layer onto to the body portion of the retroreflective sheeting opposite the optical layer, and cross-linking the image layer to form cross-links between the hydroxyl functional groups of the polymer resin and the isocyanate functional groups of the cross-linking agent.

International Classification:

A62B 7/10

US Classification:

12820125, 12820612

Abstract:

A filtering device that includes a housing having a plurality of subsections , and where each subsection is adapted to receive a filter element , and . An inlet is disposed at a first location on the housing , and an upstream air distribution system is placed in fluid communication with the inlet and with each of the subsections , and . A downstream air distribution system is located in fluid communication with each subsection , and , and an outlet in fluid communication with the downstream air distribution system. The upstream and downstream air distribution systems are constructed to cause the same airflow velocity through each subsection. Using such a construction, overall product service life may be increased while minimizing pressure resistance of the total filter.

Abstract:

A filtering device that includes a housing having a plurality of subsections , and where each subsection contains a filter element , and . An inlet is disposed at a first location on the housing , and an upstream air distribution system is placed in fluid communication with the inlet and with each of the subsections , and . A downstream air distribution system is located in fluid communication with each subsection , and , and an outlet is in fluid communication with the downstream air distribution system. The subsections are fashioned such that each subsection , and is not in fluid communication with each other. Using a filtering device so constructed, airflow through the device may be better managed to enable overall product service life to be increased while minimizing pressure resistance of the total filter.

Abstract:

An automatic-darkening filter that comprises a first polarizer a second polarizer a first liquid-crystal cell and a sensor The first polarizer has a first polarization direction, and the second polarizer has a second polarization direction. The liquid crystal cell is disposed between the first and second polarizers and contains first and second optically-transparent, flexible, glass layers and with the liquid crystal layer being located between these layers. The sensor detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.
