Patent number: 7025847Abstract: The present invention provides a new sheeting article that may suitably include: a carrier having a first major surface and a second major surface; and a plurality of discrete segments of a sheeting (e.g., a retroreflective sheeting), wherein the sheeting has a first major viewing surface and a second major opposing surface, and the first major viewing surface of the sheeting is preferably removably attached to the second major surface of the carrier. Preferably, the first major surface of the carrier comprises a release surface, the second major opposing surface of the sheeting comprises an adhesive, the article is provided in the form of a roll, and the adhesive surface of the sheeting is adjacent the release surface of an adjacent layer of the roll. In a presently preferred embodiment the present invention provides novel easy-to-use truck conspicuity sheeting.Type: GrantFiled: June 26, 2003Date of Patent: April 11, 2006Assignee: 3M Innovative Properties CompanyInventors: Eugene H. Carlson, James C. Coderre, Christopher L. Harvey, James E. Lasch, David W. Meitz, Colleen C. Nagel

Patent number: 5498549Abstract: A sensor for measuring the concentration of an analyte in a medium is disclosed. In one embodiment, the sensor comprises a sensing element including a matrix material and, covalently bonded thereto, one or more monomeric indicator components each of which is capable of providing a first emitted signal of a given wavelength in response to being exposed to an excitation signal. The sensing element is capable of providing a second emitted signal having a longer wavelength than the first emitted signal or signals in response to being exposed to the excitation signal, the second emitted signal being provided by an excimer component produced in the sensing element from the monomeric indicator component(s) and being dependent on the concentration of the analyte in the medium to a greater extent than the first emitted signal or signals.Type: GrantFiled: January 18, 1995Date of Patent: March 12, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Colleen C. Nagel, James G. Bentsen, Masao Yafuso, Alan R. Katritzky, John L. Dektar, Cary A. Kipke

Patent number: 4971725Abstract: Compositions of matter and methods of preparation are described for water and air stable, square planar transition metal double-complex salts which contain isonitrile ligands derivatized with long chain aliphatic groups. These salts are composed of two metal-containing complex ions: the cation is a tetrakis isonitrile metal ion and the anion is a tetrahalometallate or tetracyanometallate. These double-complex salts exhibit the novel property of thermochromism and are useful as temperature indicators and in imaging applications.Type: GrantFiled: February 28, 1989Date of Patent: November 20, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventor: Colleen C.
