Patent number: 6834612Abstract: Provided is a dispenser for dispensing particles onto a surface comprising a hopper for receiving particles, wherein the hopper has an opening at its bottom, a screen having openings and located adjacent the opening of the hopper, wherein the screen openings are uniformly sized and spaced and are sufficiently large to let the largest particles pass through during dispensing yet sufficiently small to hold the particles back when the dispenser is not operating, and means, located outside of the hopper, for moving particles from the hopper through the screen, and onto the surface. Also provided is a method of making a web with embedded particles comprising the sequential steps of making the web receptive to the particles by heating, eliminating static charges present on the web, dispensing the particles onto the web, dispersing the particles to minimize particle clumping in the web, and embedding the dispensed particles in the web.Type: GrantFiled: March 3, 2003Date of Patent: December 28, 2004Assignee: 3M Innovative Properties CompanyInventors: David C. Chambers, Glen Connell, Ranjith Divigalpitiya, David E. Livingstone, Agatona D. Monteagudo, Susan C. Noe, Tejmeen K. Sandhu

Patent number: 6569494Abstract: A method for dispensing particles onto a surface. The steps of the process include holding the particles in a hopper having a dispensing opening covered by a screen which has uniformly sized openings that are sufficiently large to allow the largest particles to pass through, yet sufficiently small to hold the particles back when the dispenser is not operating; rotating, outside the hopper, a cylindrical brush covered with regularly spaced bristles and positioned such that the bristles protrude through openings in the screen and draw particles through the screen to dispense them onto the surface; and varying the dispensing rate of the particles by at least one of (a) varying the rotation speed of the brush, (b) adjusting the distance from the screen to the central longitudinal axis of the brush, (c) adjusting the screen opening size, (d) adjusting the brush-to-screen pressure, or (e) adjusting the tension of the screen. A method of making a web with embedded particles.Type: GrantFiled: May 9, 2000Date of Patent: May 27, 2003Assignee: 3M Innovative Properties CompanyInventors: David C.

Publication number: 20010008169Abstract: Disclosed is an anisotropic conductive adhesive having an adhesive layer and conductive particles individually adhered to the adhesive layer, the conductive particles being arranged in an ordered array. The size of the conductive particles is at least somewhat smaller than the thickness of the adhesive layer. Also disclosed is an anisotropic conductive adhesive having an adhesive layer, conductive particles individually adhered to the adhesive layer, and a release liner having an ordered array of dimples. The conductive particles reside in a single layer in the dimples. The anisotropic conductive adhesive is made by placing the conductive particles in an ordered array of dimples on a low adhesion surface. An adhesive layer is then laminated on top such that the conductive particles individually adhere to the adhesive layer. The anisotropic conductive adhesive may be used to electrically connect fine pitch electrodes on opposing circuit layers.Type: ApplicationFiled: June 30, 1998Publication date: July 19, 2001Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: GLEN CONNELL, BERRY S.

Patent number: 5446270Abstract: Composition comprising (a) susceptors having the capability of absorbing microwave energy, said susceptors comprising a particulate substrate substantially non-reflective of microwave energy and a coating capable of absorbing microwave energy, and (b) a matrix substantially non-reflective of microwave energy. Susceptors are typically particles having a thin-film coating thereon. The matrix typically comprises polymeric or ceramic materials that are stable at temperatures conventionally used in microwave cooking. The composition allows reuse of the susceptors, eliminates decline in heating rate, eliminates arcing, allows the heating rate to be controlled, allows overheating to be controlled, and allows formation of microwave heatable composite materials having very low metal content.Type: GrantFiled: January 12, 1994Date of Patent: August 29, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Craig S. Chamberlain, Glen Connell, Pierre H. LePere, Chris A. Minick, Charlotte M. Palmgren, William C. Tait, George F. Vesley, Patrick G. Zimmerman

Patent number: 5389434Abstract: An electromagnetic radiation absorbing material comprises doubly layered core particles dispersed in a dielectric binder material. The first layer dissipates radiation; the second layer is an insulating material which helps prevent the particles from conductively contacting each other, and prevents degradation of the first layer. The absorber may be applied to an electrically conductive material, and an impedance matching material may be used.Type: GrantFiled: September 8, 1992Date of Patent: February 14, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Craig S.
