Patent number: 6120026Abstract: Game with a privacy member. The game includes a play region and a directional viewing screen. The directional viewing screen covers at least a portion of the play region such that said portion of the play region is viewable therethrough at a first player position, but is not viewable therethrough at a second player position. The game with privacy member in accordance with the present invention allows for enhancement of existing games, as well as for the creation of new games or new play patterns of existing games.Type: GrantFiled: January 13, 1998Date of Patent: September 19, 2000Assignee: 3M Innovative Properties Co.Inventors: Leland R. Whitney, Myron K. Jordan, Thomas J. Scanlan, Gregory D. Allen

Patent number: 5974757Abstract: Enclosure 1 constructed of panels 20 which can be joined by tongue and groove or press fit spline 46 and groove 26 technique. Acoustic shielding is achieved by properly selected materials of construction, e.g. syntactic, cellular composites.The doorway 10 of the enclosure is closed by a door 210 penetrated only by a guide 175. The latch mechanism 170 and 340 seals the door against the door jamb 185 by means of cam rollers 316 which engage indentations 189 (which may have specialized cam surfaces or inclined surfaces) along the door frame. The latch mechanism can be actuated from either side of the door by mechanical means engaging the guide.Type: GrantFiled: September 29, 1998Date of Patent: November 2, 1999Assignee: 3M Innovative Properties CompanyInventors: Leland R. Whitney, Thomas J. Scanlan, Charles A. Marttila, Ronald W. Gerdes, David W. Schilling, Joseph G. Mandell, Gary N. Harvieux

Patent number: 5658656Abstract: A method of using a material as an acoustical barrier in an ambient medium. The material comprises microbubbles having average outer diameters of 5 to 150 microns, bound together at their contact points. The material is characterized by either a porosity of 20 to 60 percent, or by voids between the microbubbles which have characteristic diameter within an order of magnitude of the viscous skin depth of the ambient medium, as calculated at 1 kHz; an air flow resistivity of 0.5.times.10.sup.4 to 4.times.10.sup.7 mks rayls/meter, and an attenuation of sound comparable to mass law performance. The microbubbles can be sintered into direct contact with each other, or one of many types of binder material can be used to support the microbubbles within a composite material.Type: GrantFiled: August 3, 1995Date of Patent: August 19, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Leland R. Whitney, Michael W. Dolezal, Ronald W. Gerdes, Gary N. Harvieux, Charles A. Marttila, Joseph G. Mandell, Thomas J. Scanlan

Patent number: 5418339Abstract: The present invention relates to a pneumatic tool having superior sound muffling performance. The pneumatic tool has an exhaust port, wherein a sound muffling structure comprising a nonwoven web of fibers coated with a binder resin, is fitted in said exhaust port to seal said exhaust port, wherein said fibers have diameters of about 30 to about 100 microns and wherein the web has a compression resistance energy of about 0.09 to about 0.14 Joules.Type: GrantFiled: July 18, 1994Date of Patent: May 23, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gloria D. Bowen, Zubin P. Daruwala, David W. Hegdahl, Thomas J. Scanlan, Jeffrey W. McCutcheon

Patent number: 5104632Abstract: Hydrated sodium silicate particles can be expanded by heat to form thin-walled bubbles that can be broken, neutralized, washed and dried to provide hydrated silica flakes. These flakes can be mixed with non-swelling sorptive particles such as TLC grade silica and used to make chromatographic articles. One such article is a composite of a poly(tetrafluoroethylene) fibril matrix in which those particles and hydrated or fired silica flakes are enmeshed. The hydrated silica flakes can be fired to a refractory state and then incorporated into protective coatings to enhance their resistance to abrasion while also better protecting the coated substrates from corrosion.Type: GrantFiled: June 19, 1990Date of Patent: April 14, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: David K. Douden, Thomas J. Scanlan
