20110303373 | APPARATUS FOR SEPARATING PARTICLES AND METHODS FOR USING SAME - An apparatus suitable for separating particles and methods for using such apparatus are provided. | 12-15-2011 |
20120253769 | Systems and Methods for Airborne Particle Contamination Control - The present invention relates to a method for airborne particle contamination control, comprising: creating a simulation by modeling a turbulent airflow in an environment that includes an equipment of interest; plotting a flow parameter on the simulation to visualize a flow field of air according to a current design; creating an injection point on the simulation for particles in the environment; determining a particle concentration of the particles; determining, by a computing device and from the particle concentration, whether the current design provides contamination control; in response to determining that the current design does not provide contamination control, creating a modified design; and providing the modified design for implementation. The present invention further relates to a computing device for airborne particle contamination control. The present invention still further relates to a non-transitory computer-readable medium for airborne particle contamination control. | 10-04-2012 |
20120317742 | METHOD AND APPARATUS FOR PARTICULATE REMOVAL FROM MOVING PAPER WEBS - An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer. | 12-20-2012 |
20120318298 | METHOD AND APPARATUS FOR PARTICULATE REMOVAL FROM MOVING PAPER WEBS - A method for removing dust-carrying air from a moving paper web is disclosed. The method includes the steps of: providing a moving web, the web having a first side and a second side, the web moving at a sufficient rate to produce a boundary layer of adjacent dust-carrying air; providing a NACA duct, the NACA duct having an intake opening and walls that diverge in increasing cross-sectional area to an exhaust opening having greater cross sectional area than the intake opening; and submerging the intake opening into the boundary layer to scavenge dust-carrying air from the boundary layer. | 12-20-2012 |
20130186580 | HARDWOOD PULP FIBER-CONTAINING STRUCTURES AND METHODS FOR MAKING SAME - Hardwood pulp fiber-containing structures, more particularly to eucalyptus pulp fiber-containing fibrous structures that may exhibit improved fiber densification and/or improved softness compared to known hardwood pulp fiber-containing fibrous structures are provided. | 07-25-2013 |
20130337713 | APPARATUS FOR SEPARATING PARTICLES AND METHODS FOR USING SAME - An apparatus suitable for separating particles and methods for using such apparatus are provided. | 12-19-2013 |
20140123432 | METHOD AND APPARATUS FOR PARTICULATE REMOVAL FROM MOVING PAPER WEBS - An apparatus for removing particulate-carrying air from a moving web. The moving web has a first side and a second side. The apparatus includes a NACA duct positioned in a non-contacting relationship on a first side of the moving web, and at least partially submerged in a particulate-carrying boundary layer of the moving web. The NACA duct can have an intake opening and an exhaust opening such that when the intake opening is submerged in the boundary layer at least a portion of the particulate-carrying air from the boundary layer enters the intake opening and exits the exhaust opening, thereby scavenging particulate-carrying air from said boundary layer. | 05-08-2014 |
20140231568 | FIBROUS CORES - The present disclosure is directed to a fibrous core comprising a fluted layer; and a liner disposed on the fluted layer. The fluted layer and the liner are helically wound defining a longitudinal core axis. | 08-21-2014 |
