Patent number: 8333360Abstract: Disclosed herein are polymeric molds that can be used to make molded articles. The polymeric molds are made from cyclic olefin polymers that may be formed by ring opening metathesis polymerization (ROMP) of a polycyclic monomer having two or more reactive double bonds and a cyclic monomer comprising one reactive double bond. Fluorinated monomers may be used. The polymeric molds may be structured molds in that they have at least one microstructured feature having a dimension of less than about 2 mm, or less than about 500 um. The polymeric molds may also have a plurality of such microstructured features. Also disclosed herein are methods of making the polymeric molds, methods of making molded articles therefrom, and the molded articles.Type: GrantFiled: April 28, 2009Date of Patent: December 18, 2012Assignee: 3M Innovative Properties CompanyInventors: Joseph D.

Patent number: 8329851Abstract: A functionalized polymer is disclosed that comprises the reaction product of a polymer having one or more pendant reactive functional groups and a color changing indictor having a co-reactive functional group. The co-reactive functional group of the color changing is able to react with the reactive functional group of the polymer to form a covalent bond. Therefore, the color changing indicator is pendant from the polymer. The color changing indicator maintains its ability to produce a visually discernable color change in the presence of an associated stimulus.Type: GrantFiled: June 27, 2008Date of Patent: December 11, 2012Assignee: 3M Innovative Properties CompanyInventors: Yifan Zhang, Yi He, Diane R. Wolk, Mark W. Nelson, Larry Richard Krepski, Stephen Richard Hartshorn, Douglas Eugene Weiss

Patent number: 7845582Abstract: A spray gun reservoir has an oversize central opening 130 at one end allowing liquid to be added to the reservoir for fast filling with reduced risk of spillage. A cap member 132 is connectable to the reservoir and has a spout 115 providing a fluid outlet of reduced size relative to the opening 130 for connection to the spray gun. The reservoir can be disconnected from the cap member 132 when it is desired to add liquid to the reservoir. In this way, the reservoir can be re-filled in use.Type: GrantFiled: October 27, 2003Date of Patent: December 7, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C. P. Joseph, Daniel E. Siltberg

Patent number: 7798426Abstract: A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastic material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.Type: GrantFiled: June 30, 2004Date of Patent: September 21, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C. P. Joseph, Malcolm F. Douglas, Alan F. Butler

Patent number: 7798427Abstract: A spray gun (1) has a fluid reservoir (11) with a removable liner (13) received in a container (12) having a detachable lid (15). The liner (13), which may be thermo/vacuum-formed from a planar material, has a shape that corresponds to and is a close fit within the interior of the container (12) and collapses as fluid is withdrawn from within the liner (13) during operation of the spray gun (1). The lid (15) has an outlet (16) connected to an inlet on the spray gun (1) for transfer of liquid from the reservoir (11) to the spray gun (1) and the container (12) has a vent (12A) in the base end for admitting air between the container (12) and the liner (13) as liquid is withdrawn from within the liner (13).Type: GrantFiled: March 23, 2006Date of Patent: September 21, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C. P. Joseph, Malcolm F. Douglas, Alan F. Butler

Patent number: 7712682Abstract: A reservoir (402) for connection to a spray gun has a lid (410) provided with an outlet spout (415) that is rotatably received in a socket of an inlet adaptor (419) connectable to the spray gun. The lid (410) has a spring leg (425) spaced from the outlet spout (415) with a projection (426) at the distal end for self-latching engagement with a flange (423) of the adaptor (419) to secure releasably the reservoir (402) to the spray gun. The engagement of the projection (426) and flange (423) enables the reservoir (401) to be rotated through 360° to adjust the position of the reservoir (402) while attached to the spray gun.Type: GrantFiled: March 12, 2004Date of Patent: May 11, 2010Assignee: 3M Innovative Properties CompanyInventors: Stephen C.
