Publication number: 20120060718Abstract: A sensor head-transporting roller carriage has four pairs of wheels acting around pivot points at the four corners of the carriage, which is advanced along tracks that are supported by vertical structures. The lateral wheel spacing is chosen in correlation with the track support interval distances such that the vertical travel of all the wheels together is averaged, to be zero. As a result, variations in displacement alignment of the sensor are minimized. In addition, the pivot mechanism results in a fifty percent reduction in the effect of random vertical deflections caused by track debris or wheel concentricity etc. versus standard non-pivoting wheel sets. The roller carriage moves the sensor head along the cross direction to monitoring physical characteristics of a web of material that is moving in the machine direction.Type: ApplicationFiled: September 15, 2010Publication date: March 15, 2012Applicant: Honeywell ASCa Inc.Inventor: Ron Beselt

Publication number: 20120049070Abstract: An apparatus for incorporation into time-domain spectroscopy systems that creates a continuous reference whereby a sample pulses' phase and amplitude can be tracked and corrected employs a beam splitter to generate sample and reference pulses. A detector is positioned for receiving the reference radiation pulses that do not interact with the sample. The same detector is also positioned for receiving the sample radiation pulses that emerge from the sample. The apparatus can be readily implemented by being configured between the emitter and detector of a terahertz time-domain spectrometer. The reference pulse is used to trace the changes in time and amplitude of the sample pulse. Since any changes in the reference pulse will most likely manifest in the sample pulse, the reference pulse is monitored and used to correct the sample pulse and thereby reduce the effects of jitter.Type: ApplicationFiled: August 24, 2010Publication date: March 1, 2012Applicant: Honeywell ASCa Inc.Inventors: Payam Mousavi, Steven Dodge, Frank Martin Haran, Stephane Savard, David Jez, Stuart James Heath

Patent number: 8088255Abstract: An air stabilization system employing two substantially parallel, codirectional Coanda nozzles, that are positioned adjacent a flexible moving web, with each nozzle exhausting gas at the same downstream machine direction, subjects the moving web to shear forces effective to stabilize the web. Each nozzle includes an elongated slot that is substantially perpendicular to the path of the moving web and a backstep located downstream of the direction of airflow extending from the Coanda slot. The two Coanda nozzles serve as separate points along the machine direction for controlling the height of the moving web. By modulating the velocities or other parameters of gases exiting the Coanda nozzles, the shape of the moving web between the nozzles can be manipulated to present a planar contour for measurements. The air stabilization system can be incorporated into a scanner head to measure the caliper of paper, plastic, and other flexible web products.Type: GrantFiled: April 18, 2008Date of Patent: January 3, 2012Assignee: Honeywell ASCa IncInventors: Tamer Mark Alev, Salvatore Chirico

Patent number: 8085397Abstract: Fiber optic sensors employ a high brightness light source such as a fiber optic supercontinuum source, multiplexed superluminescent light emitting diodes, or a broadband tunable laser diode. Light is delivered to the measurement location via fiber optics and sensor optics directs infrared radiation onto material the being monitored that is located in a hostile environment. A disperse element is positioned in the detection beam path in order to separate the wavelengths and to perform spectral analysis. A spectral analysis of the radiation that emerges from the sheet yields information on a plurality of parameters for the material. For papermaking applications, the moisture level, temperature and cellulose content in the paper can be obtained.Type: GrantFiled: July 10, 2009Date of Patent: December 27, 2011Assignee: Honeywell ASCa Inc.Inventors: Frank Martin Haran, Ross MacHattie, Ronald E Beselt

Publication number: 20110290438Abstract: Alignment is a critical component for modeling a cross-directional (CD) papermaking process. It specifies the spatial relationship between individual CD actuators to paper quality measurements. Misalignment can occur unexpectedly due to sheet wander or CD shrinkage variation. In certain applications and circumstances, a misalignment of one third (?) actuator zone width can result in significant paper quality degradation. Detecting a misalignment and identifying CD alignment in closed loop are highly demanded in paper mills but these are nontrivial problems. A technique for maintaining proper CD alignment in sheetmaking systems entails monitoring the alignment online, triggering closed loop identification if misalignment is detected, and then deploying the new alignment. No personnel intervention is required.Type: ApplicationFiled: May 31, 2010Publication date: December 1, 2011Applicant: Honeywell ASCa Inc.Inventors: Danlei Chu, Cristian Gheorghe, Johan Backstrom

Patent number: 7899281Abstract: Optical delay line system that includes a retro-reflection mirror which is displaced along a circular path while being maintained in angular alignment with launch and return sources of light subject the components of the system to minimum levels of unbalanced linear acceleration. A retroreflector is pivotally mounted on a rotating element such that the optical axis of the retroreflector's motion is mobile such that its angle or position changes relative to a fixed observer. There is no linear stopping and starting of the retroreflector and all acceleration of the retroreflector is rotational acceleration with small angles so the required forces in the optical delay line are greatly reduced. Both large displacement and high repetition rates are achieved. The system can be configured so that optical fibers serve as launch and return optics. Alternatively, free space beam paths deliver light to the optical delay and return the reflected light from the retroreflector.Type: GrantFiled: July 8, 2008Date of Patent: March 1, 2011Assignee: Honeywell ASCa Inc.Inventor: Ronald E.
