Publication number: 20150177155Abstract: Scanning sensor for measuring properties of continuous flat sheet, that is moving in the machine direction, employs an IR radiation source for directing a beam of incident IR radiation that impinges the sheet. The IR source has elongated lamp filament that generates IR radiation and the corresponding spot size formed on the sheet has elongated dimensions with its long axis being aligned with the machine direction. Aligned with the MD maximizes sensor spatial resolution in the cross direction. The sensor can employ a receiver having rectangular geometry with its long axis being aligned also in the MD. Scanning sensor can operate in the reflective, transmissive, or offset transmission mode to monitor characteristics of flat sheets, particularly of paper or plastic products.Type: ApplicationFiled: December 23, 2013Publication date: June 25, 2015Applicant: Honeywell ASCa Inc.Inventor: Frank Martin Haran

Publication number: 20150159995Abstract: Non-contacting caliper measurements of free standing sheets such as porous polymer and paper detect mid-IR interferometric fringes created by the reflection of light from the top and bottom surfaces of the sheet. The technique includes directing a laser beam at a selected angle of incidence onto a single spot on the exposed outer surface wherein the laser beam comprises radiation having a wavelength in the 3-50 micron range and scanning the laser beam through a selected angle range as the laser beam is directed onto the exposed outer surface and measuring the intensity of an interference pattern that forms from the superposition of radiation that is reflected From the exposed outer surface and from the inner surface. Thickness can be extracted from the fringe separation in the interference pattern. Rotating and focusing elements ensure that the spot position on the sheet remains the same while varying the incident angle.Type: ApplicationFiled: December 11, 2013Publication date: June 11, 2015Applicant: Honeywell ASCa Inc.Inventors: Sebastien Tixier, Michael Kon Yew Hughes, Stephane Savard

Patent number: 9007589Abstract: Dual mounting head scanners measure the thickness of flexible moving porous webs and employ an air clamp on the operative surface of the lower head to maintain the web in physical contact with a measurement surface. As the web is held firmly by the clamp, the vacuum level that is established is indicative of the porosity of the membrane. As compressed air is supplied to a vacuum generator at a given operational pressure, the rate of airflow through the web can be inferred from the vacuum pressure measurements. The rate of airflow through the membrane and therefore the porosity of the membrane are related to the vacuum level. It is not necessary to measure the airflow through the membrane. From the vacuum pressure measurements, the membrane's permeability can also be determined by correlation to empirical data. Thickness measurements are effected by optical triangulation and inductive proximity measurements.Type: GrantFiled: September 16, 2013Date of Patent: April 14, 2015Assignee: Honeywell ASCa Inc.Inventors: Michael Kon Yew Hughes, Sebastien Tixier, Stuart James Heath

Patent number: 8997023Abstract: A user initiated move action can be detected on a selected graphical object on a flowsheet within a rendered canvas of a graphical user interface. During the user initiated move action, based a predetermined threshold distance between the selected graphical object and the other graphical objects, candidate graphical objects are identified from the other graphical objects. Provided at least one candidate graphical object is identified, at least one proposed connection is visually presented between the selected graphical object and the candidate graphical object in a contrasting visual style to a style for established interconnections between the plurality of graphical objects within the rendered canvas. Upon the user confirming the proposed connection, a new established connection is visually presented in a canvas final state to replace the proposed connection using the style for established interconnections within the rendered canvas between the selected graphical object and the candidate graphical object.Type: GrantFiled: July 15, 2010Date of Patent: March 31, 2015Assignee: Honeywell ASCA Inc.Inventors: David John Pavan, Samuel Grosvenor Norris

Patent number: 8985051Abstract: A coating apparatus produces a spray of charged droplets and controls the spray angle of travel of the spray toward the object to be coated. Electrically charging droplets minimizes the amount of coating material required to uniformly coat a surface as compared to conventional web coating techniques such as blade coating. An inductive ring guides the spray charged droplets as they exit the nozzle of a spray device. The electrostatic repulsion between the charged droplets insures that a uniform coating of liquid formulation can be applied to a web surface.Type: GrantFiled: December 15, 2011Date of Patent: March 24, 2015Assignee: Honeywell ASCa Inc.Inventor: Jonathan Crawford

Publication number: 20140358254Abstract: A method includes obtaining a reference tracking performance ratio and a disturbance rejection performance ratio associated with a model predictive control (MPC) controller. The method also includes filtering an output target signal for the controller using a first filter based on the reference tracking performance ratio. The method further includes filtering a feedback signal for the controller using a second filter based on the disturbance rejection performance ratio. The filters can provide two degrees of freedom for tuning reference tracking and disturbance rejection operations of the controller. The reference tracking operation of the controller and the disturbance rejection operation of the controller can be independently tunable. The reference tracking performance ratio can control how aggressively the controller responds to a change in the output target signal. The disturbance rejection performance ratio can control how aggressively the controller responds to a disturbance in the feedback signal.Type: ApplicationFiled: May 31, 2013Publication date: December 4, 2014Applicant: HONEYWELL ASCa, Inc.Inventors: Danlei Chu, Michael Forbes, Johan U.

Patent number: 8760669Abstract: Dual mounting head scanner system measures the thickness of a flexible continuous moving web such as paper by employing an optical senor positioned in the upper head to determine the distance between the optical sensor and the upper surface of the paper while a displacement sensor positioned in the lower head determines the distance between the displacement sensor, which includes an RF coil, and a reference surface on the upper head. An air clamp and vacuum source assembly on the operative surface of the lower head maintains the moving web in physical contact with a measurement surface that is incorporated in the operative surface. The optical sensor directs incident radiation onto the web at the measurement surface. Thermal isolation of the two sensors eliminates thermal interactions.Type: GrantFiled: September 30, 2011Date of Patent: June 24, 2014Assignee: Honeywell ASCa Inc.Inventors: Stuart James Heath, Michael Kon Yew Hughes, Graham Duck

Patent number: 8742385Abstract: Paper and continuous web scanners operate at varying and high temperature conditions that cause distortion of the support beams and ultimately misalignment of the scanner heads. Circulating a heat transfer fluid between the support beams and through segmented fluid channels within the beam allows tuning of the beam's deflection when operating in an uneven thermal environment. The heat transfer rate can be modulated through various techniques, including: (1) varying the flow rate through each channel under manual or automatic control, (2) controlling the inlet fluid temperature of each channel with fluid immersion heaters or coolers, and (3) setting up the flow sequence via distribution channels that are, for example, in parallel, serial, or mixed.Type: GrantFiled: January 26, 2011Date of Patent: June 3, 2014Assignee: Honeywell ASCa Inc.Inventors: Ron Beselt, Michael Wardas, Cris Andronic
