Patent number: 6692601Abstract: A unique isotropic sub-denier spunbond nonwoven product created by an apparatus and method comprising a unique multi-head resin metering system, a spinneret head with spinning sections, separated by a quench fluid extraction zone, a two sided, multilevel quench system, a fluid volume control infuser system which automatically guides the filaments into the filament drawing system while conserving energy by using a portion of the quench fluid as part of the drawing fluid and also minimizing turbulence at the entrance to the draw slot. The filament drawing system comprises a draw jet assembly with adjustable primary and secondary jet-nozzles and a variable width draw jet-slot. The entire draw jet assembly is moveable vertically for filament optimization. The offset, constant flow secondary jet-nozzle system provides an unexpectedly high velocity increment to the filaments by oscillating the filaments and increasing their drag resulting in remarkably low fiber denier on the order of 0.5 to 1.2.Type: GrantFiled: May 21, 2002Date of Patent: February 17, 2004Inventors: Gerald C.

Patent number: 6692602Abstract: A machine for producing corrugated cardboard incorporates a corrugating roll and a glue roll extending parallel to the former in such a way that a glue gap is formed between the two. To adjust the glue gap, the bearing of the glue roll is pushed against the bearing of the corrugating roll with a contact-pressure force A. By means of an adjusting unit the distance of the two bearings is reduced until the force of the bearing contact pressure, which is measured by a force measuring unit, decreases due to a contact occuring between the glue roll and the corrugating roll. The glue roll may have stop rings at its ends to prevent a direct contact between the glue roll and the corrugating roll.Type: GrantFiled: September 22, 2000Date of Patent: February 17, 2004Assignee: BHS Corrugated Maschinen-und Anlagenbau GmbHInventors: Hermann-Josef Mensing, Reinhard Sternitzke, Josef Puff

Patent number: 6692607Abstract: Molten polymers are forced into T dies combined to form a multiple T die, the molten polymers are extruded through the T dies as monolayers. The monolayers extruded through the T dies are superposed and laminated outside the multiple T die while the polymers are in a molten or semi-molten state to form a intermediate molten multilayer. The multiple T die is advanced into a space between an open top half mold and a bottom half mold of a compression mold to deliver the intermediate multilayer onto the bottom half mold. The intermediate multilayer is cut to a predetermined length on the bottom half mold, and is processed for compression molding in the compression mold to form a multilayer article. A molding cycle for molding the multilayer article is carried out automatically at a remarkably improved manufacturing efficiency.Type: GrantFiled: February 7, 2001Date of Patent: February 17, 2004Assignee: Toshiba Kikai Kabushiki KaishaInventors: Akinori Ide, Takehiro Yamamoto

Patent number: 6692611Abstract: A method of laminating a structure comprises at least two layers and a photopolymerizable adhesive composition between the layers, at least one of the layers being opaque, colored, or reflective. One or both of the layers is transmissive to actinic radiation in wavelengths in the range of greater than 400 nm and up to 1200 nm. The photopolymerizable adhesive composition absorbs radiation in the identified spectral region of the radiation transmissive layer. Curing is effected by directing radiation in the identified spectral region through the radiation transmissive layer and produces a laminated structure. An underfilled flip chip assembly on an integrated circuit board substrate can be prepared by the method described above.Type: GrantFiled: November 26, 2001Date of Patent: February 17, 2004Assignee: 3M Innovative Properties CompanyInventors: Joel D.

Patent number: 6692612Abstract: Novel compositions and methods of using the same which are highly effective at removing adhesive materials. The compositions are useful for removing adhesives, such as those used to secure floor coverings, to thereby aid in the removal of the floor covering. Additionally, the present invention is also directed to methods of removing adhesives and floor coverings using the compositions of the present invention. The present invention uses compositions comprising an alkaline amine reagent, preferably an alkaline aliphatic amine reagent, either alone or coupled with a non-ionic wetting agent. These compositions may be applied to an adhesive. The compositions break down the adhesive, thereby allowing it to be easily removed. Alternatively, to remove a floor covering such as carpet or tile, the composition may be applied directly to the floor covering such that it penetrates the floor covering and contacts the adhesive to break-down the adhesive and permit the easy removal of the floor covering.Type: GrantFiled: April 13, 2000Date of Patent: February 17, 2004Inventor: Michael Spratling

Patent number: 6692613Abstract: A method for processing a semiconductor wafer or similar article includes the step of spinning the wafer and applying a fluid to a first side of the wafer, while it is spinning. The fluid flows radially outwardly in all directions, over the first side of the wafer, via centrifugal force. As the fluid flows off of the circumferential edge of the wafer, it is contained in an annular reservoir, so that the fluid also flows onto an outer annular area of the second side of the wafer. An opening allows fluid to flow out of the reservoir. The opening defines the location of a parting line beyond which the fluid will not travel on the second side of the wafer. An apparatus for processing a semiconductor wafer or similar article includes a reactor having a processing chamber formed by upper and lower rotors. The wafer is supported between the rotors. The rotors are rotated by a spin motor. A processing fluid is introduced onto the top or bottom surface of the wafer, or onto both surfaces, at a central location.Type: GrantFiled: August 20, 2002Date of Patent: February 17, 2004Assignee: Semitool, Inc.Inventors: Steven L.
