Publication number: 20230100957Abstract: Surface treated silica containing particles are combined with a resin to form a liquid prepolymer composition for use in additive manufacturing. A surface treatment on the silica containing particles may participate in polymerization of the composition. The silica containing particles may be colloidal silica or a silica polymer composite particle.Type: ApplicationFiled: February 3, 2021Publication date: March 30, 2023Inventors: Dmitry Fomitchev, Paul S. Palumbo, Jodi A. Bates, Xiaofeng Zhang, Russell H. Lewis, Eugene N. Step, Andriy Korchev, Joshua M. Wimble, Patrick Sargent, Bjoern Schimmoeller

Publication number: 20130045380Abstract: A filled multi-component material applied by a dispensing system is disclosed. The material can be produced by mixing a first reactive component comprising a resin and a filler with a second reactive component comprising a curing agent. The filler can comprise a hard filler and/or an elastic filler such as ground recycled tire material. The first reactive component and the second reactive component can be fed to a dispensing apparatus and mixed by a static mixer, each of which can be disposable. The mixture can then be dispensed onto a surface using air spray, airless spray or extrusion, for example. When applied to a surface, the mixture typically polymerizes and entrains the filler materials to provide a protective layer having improved properties. In certain embodiments, the filler materials can include recycled tires that have been ground into fine particles, providing environmentally friendly new products from old tires that typically end up as landfill.Type: ApplicationFiled: January 21, 2010Publication date: February 21, 2013Applicant: RHINO LININGS CORPORATIONInventors: Russell H. Lewis, Mihai Adrian Solomon

Publication number: 20020088876Abstract: Apparatus and method for delivering single or multi-component material through a disposable delivery tube and atomizing the material into a spray pattern of substantially uniform dispersion. The apparatus includes a tubular manifold having an opening for receiving a disposable delivery tube with the exit end or nozzle of the delivery tube projecting out from the end of the manifold. A plurality of atomizer holes are formed in the end of the manifold surrounding the hole which receives the nozzle end of the delivery tube. A source of air under pressure is connected to direct air through the atomizer holes. An air cap is mounted to the manifold to direct air passing through the atomizer holes about the nozzle of the delivery tube to atomize the delivered material into a uniform spray pattern without the material coming into contact with either the manifold or the air cap.Type: ApplicationFiled: January 22, 2002Publication date: July 11, 2002Inventors: Russell H. Lewis, Mihai A. Solomon

Patent number: 6179196Abstract: Apparatus for connecting a first area array component to a substrate with a joining material. The apparatus has a nozzle directing heat toward both the first area array component and the portion of the substrate beneath the first area array component to melt the joining material. An elastic seal contacts the substrate and prevents the heat from affecting other components adjacent the first area array component. The nozzle is pressed against the substrate to restrain warping of the substrate, which might be caused by the heating of the first area array component, and to prevent damage to the substrate. The nozzle can tilt so that it conforms to the surface of the substrate. The first area array component is allowed to move freely in the direction of a plane of the substrate under the surface tension of the molten joining material during heating to center the first area array component.Type: GrantFiled: February 7, 2000Date of Patent: January 30, 2001Assignee: International Business Machines CorporationInventors: Craig G. Heim, Russell H. Lewis, Mark V. Pierson, Karl J. Puttlitz

Patent number: 5862588Abstract: A method for producing interconnect structures and circuit boards including placing an area array component having connection bumps on the corresponding metal contacts on a substrate disposed on a backing plate, providing heat curable joining material in communication with the bumps and contacts, contacting a gas nozzle directly to a portion of the substrate surrounding the component to press the substrate between the nozzle and the backing plate to restrain the substrate from wrapping, heating the component, the joining material and the substrate proximate the metal contacts while maintaining the nozzle on the substrate to cure the joining material, and cooling the component, the joining material and the substrate. Selected components can also be replaced utilizing the gas nozzle for restraining the substrate from wrapping.Type: GrantFiled: August 14, 1995Date of Patent: January 26, 1999Assignee: International Business Machines CorporationInventors: Craig G.

Patent number: 5735450Abstract: An apparatus for heating a module mounted on a card includes a heating chamber adapted to receive the card and module, a nozzle adapted to surround the module and provide a flow of heated gas thereover, and a heated support surface for heating a bottom surface of a card immediately underlying the module. The method of removing and replacing a module on a card includes preheating the card and module prior to heating the contact sites to a solder reflow temperature and also preheating a card and a replacement module to an equilibrium temperature prior to increasing the temperature of the contact sites to the reflow temperature. The apparatus and method embodying the present invention effectively addresses the problem of providing a faster heating cycle, and a more even temperature distribution across the contact sites of the module and card.Type: GrantFiled: June 21, 1996Date of Patent: April 7, 1998Assignee: International Business Machines CorporationInventors: Craig Grant Heim, Christian Robert Le Coz, Russell H.
