Patent number: 8236377Abstract: Method and system for moving a frozen adhesive particle towards a target body, comprising launching means (13) which are arranged to launch the particle (2) in its frozen form towards the target body (3, 4) via a movement path (14) through a gap (15) between the launching means and the target body. The medium in the gap may have a temperature above the adhesive particle's melting temperature. The launching means may be arranged to launch the particle at a high speed. The launching means and the target body may have a geometry causing that the movement path is substantially vertical or substantially horizontal.Type: GrantFiled: December 4, 2006Date of Patent: August 7, 2012Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Erik Christian Nicolaas Puik, Edwin Johannes Theodorus Smulders

Publication number: 20120183684Abstract: A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. In one embodiment a blend drop conveyor has an upper flight urged into a concavity by an outside, third roller. The conveyor is configured to receive granules at a first speed in an area near the convergence of the upper flight and the third roller, and to traject them on a second path at a second speed near the sheet speed of the substrate below. The applicator thus changes the speed and direction of the granules, to cause them to land on the substrate with good edge definition and minimal splatter.Type: ApplicationFiled: January 13, 2011Publication date: July 19, 2012Applicant: OWENS CORNING INTELLECTUAL CAPITAL, LLCInventor: David P. Aschenbeck

Publication number: 20120183685Abstract: A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. One embodiment includes a rotating drum having openings that connect the interior space and an exterior of the rotating member. A granule dispenser is mounted within the interior space of the drum for dispensing granules there. A belt wraps around a major portion of the outside of the drum leaving an uncovered area. As the drum rotates within the belt, the granule openings move between a position closed by the belt and retaining granules by centripetal force and an open position wherein the granules are flung from the drum to a substrate. Doors may be used instead of a belt.Type: ApplicationFiled: January 13, 2011Publication date: July 19, 2012Applicant: OWENS CORNING INTELLECTUAL CAPITAL, LLCInventor: David P. Aschenbeck

Patent number: 8210118Abstract: A breading machine for dispensing a coating material onto a food product includes a breading chamber, a continuous conveyor for transporting food products through the breading chamber, a hopper including at least one downspout and a sloped bottom for dispensing coating material onto the food products, a hopper conveyor positioned within the hopper. At least one of an angular position or a vertical position of the hopper conveyor is adjustable to accommodate a variety of free flowing and non-free flowing coating materials. One or more air knives may be positioned in the downspouts to fluidize the coating material to alleviate bridging and/or build-up of the coating material within the downspout.Type: GrantFiled: September 9, 2008Date of Patent: July 3, 2012Assignee: John Bean Technologies CorporationInventors: Robert M. Stacy, Jeffery L. Schoewe, Michael E. Miller, John Joseph Bauer, Jogesh Chandran, Roy Allen Schippel

Publication number: 20120141657Abstract: A method for adjusting the track of a granule-coated sheet includes moving a granule-coated sheet around a drum. The granule-coated sheet includes first granules. A track of the granule-coated sheet is sensed at the drum. A first signal is generated when the granule-coated sheet has moved off a pre-designated track. Second granules are applied to a lane portion of the granule-coated sheet prior to the drum in response to the first signal. The second granules make the granule-coated sheet thicker in the lane portion relative to a thickness of the granule-coated sheet outside the lane portion.Type: ApplicationFiled: December 3, 2010Publication date: June 7, 2012Applicant: OWENS CORNING INTELLECTUAL CAPITAL, LLCInventor: David P.

Publication number: 20120137969Abstract: A nozzle for a powder spray gun optionally includes an internal filter that allows air to be added to the powder flow within the nozzle shell. The nozzle may optionally include an off-axis outlet slot relative to a main flow axis of the powder into the nozzle shell so that powder encounters an obstruction before exiting through the outlet slot.Type: ApplicationFiled: January 31, 2012Publication date: June 7, 2012Applicant: NORDSON CORPORATIONInventors: Terrence M. Fulkerson, Michael R. Sanner, Brian D. Mather, Joseph G. Schroeder, Jeffery Edward Dailidas

Patent number: 8176869Abstract: A production assembly and associated process for mass producing such as a thermoplastic pallet and which utilizes a multiple insert supporting and continuously moving carousels inter-faceable with an input line upon which is transported a plurality of rigid and planar shaped inserts, as well as an output line a spaced relationship from the input line for removing, from the carousel, the resin coated articles. The invention further teaches a series of subset variants for spray applying a two part resin and hardener upon the insert according to a selected thickness, following which the inserts are cured and dried prior to transferring to the output line and in order to create a finished product.Type: GrantFiled: May 18, 2009Date of Patent: May 15, 2012Assignee: Oria Collapsibles, LLCInventor: Miguel A. Linares

Patent number: 8173207Abstract: An arrangement for depositing coating powder on a rotational symmetric body is provided. The arrangement includes a rotation device for rotating the rotational symmetric body around a horizontal axis of rotation, wherein the horizontal axis of rotation coincides with the axis of the rotational symmetry of the body, a nozzle arranged vertically above a surface of the rotational symmetric body for providing the coating powder to the surface and a horizontal barrier at a specified distance defining a coating thickness above the surface, wherein the barrier is arranged next to the nozzle in the direction of a rotational movement of the surface at the nozzle. At this point, the nozzle includes a cross section elongated in one direction parallel to the axis of rotation.Type: GrantFiled: December 14, 2010Date of Patent: May 8, 2012Assignee: Siemens AktiengesellschaftInventor: Ulf Simmons
