Patent number: 7690902Abstract: Melt blown or spun bond nonwoven webs are formed by flowing fiber-forming material through a die cavity having a substantially uniform residence time and then through a plurality of orifices to form filaments, using air or other fluid to attenuate the filaments into fibers and collecting the attenuated fibers as a nonwoven web. Each die orifice receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.Type: GrantFiled: June 15, 2007Date of Patent: April 6, 2010Assignee: 3M Innovative Properties CompanyInventors: Stanley C. Erickson, James C. Breister, Michael G. Schwartz, Patrick J. Sager

Patent number: 6824733Abstract: Melt blown nonwoven webs are formed by supplying fiber-forming material to a planetary gear metering pump having a plurality of outlets, flowing fiber-forming material from the pump outlets through a plurality of inlets in one or more die cavities, and meltblowing the fiber-forming material. Each die cavity inlet receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship.

Publication number: 20020110610Abstract: An apparatus for charging fibers that contain a nonconductive polymer. A polar liquid 32, 34 is sprayed onto free-fibers 24, and the free-fibers 24 are then collected to form an entangled nonwoven fibrous web 25 that may contain a portion of the polar liquid. The nonwoven web 25 is then dried 38. By applying an effective amount of polar liquid 32, 34 onto the nonconductive free-fibers 24 before forming the nonwoven web 25, followed by drying 38, the individual fibers 24 become charged. The apparatus can enable the fibers 24 to be charged during web manufacture without subsequent processing.Type: ApplicationFiled: February 12, 2002Publication date: August 15, 2002Applicant: 3M Innovative Properties CompanyInventors: Seyed A. Angadjivand, Michael G. Schwartz, Philip D. Eitzman, Marvin E. Jones

Patent number: 6135658Abstract: Thermal printer donor media element (10) with a single track of code including sequential code segments (30). The present donor media element (10) includes sequential color patches (12, 14, 16) which form multiple color groups (18) located along the length of the element (10), and the code segments (30) are arranged in corresponding repetitive groups located adjacent the color groups (18), the sequential code segments including fields of encoded data representative of at least donor media type, and color and location of successive ones of the color patches (12, 14, 16). Apparatus for detecting and reading the encoded data include a single sensor (38) and a processor (44) operable for accurately completing incomplete or incorrectly detected data.Type: GrantFiled: June 24, 1999Date of Patent: October 24, 2000Assignee: Eastman Kodak CompanyInventors: Samuel Reele, Michael G.

Patent number: 4052306Abstract: A floatable oil sweep useful in controlling an oil spill on a moving body of water comprises an elongated web of oil sorbent adapted to float on the body of water with its large-area faces parallel to the waterline, and a weighted open-mesh netting attached to the web and adapted to be suspended below the floating web when the oil sweep is deployed. Use of the netting has been found to significantly extend the period of time before oil droplets are carried under the oil sweep by movement of the body of water.Type: GrantFiled: October 12, 1976Date of Patent: October 4, 1977Assignee: Minnesota Mining and Manufacturing CompanyInventors: Michael G. Schwartz, Alan P. Lorentzen, David J. Bucheck
