Patent CA-2026909-A1 (CA)
IPC: G01S7/292
Filed: 1990-10-04
Abstract: SYNERGISTIC TRACKER                 ABSTRACT OF THE INVENTION Target  tracking  capability  is  provided  by  a synergistic tracker system (5) which includes both a correlation tracker (30) and an object tracker (40) for processing sensor data input (10)  and for generating tracking error signals (80).   The  operation of  the synergistic tracker system is controlled by central processing unit  (70).   The system operates by first correlating a reference region image with a portion of a current digitized image provided by analog to digital converter (20).  Secondly, the object tracker provides a precisely defined trackpoint for an object within the current image.  The correlation tracker stabilizes and limits the portion of the digitized image that the object  tracker must  operate upon.   Stabilizing  and limiting this portion of the digitized image reduces the object tracker's sensitivity to background clutter and sensitivity to a loss of lock induced by sensor motion.   The object tracker provides a non-recursive update for the correlation's reference region image. The correlation tracker and the object tracker are used simultaneously and cooperatively so that the strengths of a one tracker are used to overcome the weaknesses of the other.  The invention achieves a greater tracking tenacity,  a reduction in tracker angle noise,  and a reduction in hardware complexity.

Title: Protective latex coating and method of using the same
Inventor: WEDDERBURN JAMES W
IPC: B41M7/02
Filed: 1990-10-16
Abstract: ABSTRACT OF THE DISCLOSURE    The  invention  disclosed  is a protective coating and  a  method  applying  the  same  to  protect  paper substrates  such  as  maps and newspaper clippings from harsh environmental conditions such as rain, grease and rough handling.  Two different film forming latexes are applied in a specific  order  to  a  substrate  at room temperature. The  first film  is a  latex which has the following properties; water  resistance,  resistance to discoloration, flexibility, transparency, resistance to degradation over  time, a  glass transition temperature of less than thirty degrees celsius. The second film is a latex which has the following  properties; resistance to  discoloration,  transparency,  resistance  to  film degradation  over  time,  resistance  to  stickiness, a glass transition temperature of greater than 10 degrees celsius.  The   resulting   coating   is a  flexible, waterproof,   transparent   coating   that   tends   to strengthen  the  substrate,  protect   it  from water, grease, rough  handling and  will not yellow or degrade over time and results in  a  substrate  which  will not bond  to  itself  when  it  is  folded and subjected to temperatures that reach up to seventy degrees celsius.          In addition, the adding of a W absorber to one or both latexes  helps  in  protecting  ultra  violet sensitive substrates such as newspaper from discoloration.

Title: Apparatus and method for a catheter adapter with valve
IPC: A61M39/00
Filed: 1991-05-27
Abstract: CATHETER ADAPTER WITH VALVE     ABSTRACT OF THE DISCLOSURE       An over the needle catheter with adapter that has an integral valve in a passage.   Distal and proximal parts form  the  adapter  along  an  axis.   The  distal  part communicates with a catheter.  A hub conjugates with the proximal part and has a needle extending along the axis and  through  the  passage  when  the  hub  is  within  the proximal part.  A valve assembly has an elongate resilient member  captured  in  the  passage  between  the  parts.   A proximal  portion of  the valve assembly is engaged by a fitting to open the valve.  A valve seat in the passage has  a  frusto-conical  surface located coaxial  about  the axis  and facing the  distal  part.   The  seat  engages  a chamfered surface on the elongate resilient member to seal and prevent flow and to allow flow when the seal is broken by axial compression of the elongate resilient member by the  fitting.   A  septum  like  end  across  the  elongate resilient member permits the needle to pass therethrough in a resealable fashion.   The  elongate  resilient member has a diametrically reduced cylindrical body extending to the septum like end.   The passage has  an annular  space about the reduced cylindrical  body  and terminates in a distal  area.   The distal area  has  flow  channels  which extend between the annular space and the distal part.  A method has steps of locating the parts along an axis and capturing the  elongate  resilient member by engaging the axially  aligned  parts  to  force  the  elongate  resilient member against a valve seat for sealing the passage and preventing flow.  Placing a needle carried on a hub along the axis and through a septum like end of the elongate resilient member allows the needle to be withdrawn from the septum like end and to reseal the passage.  Applying fastening means to secure the parts is a step.

Abstract: A  bearing  apparatus is disclosed for permitting axial rotational  and  angular  movement  of a doctor journal of a papermaking machine.  The apparatus includes a housing which defines  a cylindrical bore for the reception therein of the doctor  journal.   An  annular bearing ring defines an inner and   an   outer   surface  with  the  outer  surface  being cylindrical  and  having  a  diameter slightly less than the diameter  of  the  bore  such that when the ring is disposed within  the  bore,  axial sliding of the bearing ring within the bore  is  permitted.   A  sleeve is disposed within the bearing  ring  with  the sleeve defining an internal channel for   supporting   the  doctor  journal. The  sleeve  also defines an external face which closely conforms to the inner surface  of  the  bearing ring such that angular movement of the  sleeve within the bearing ring is permitted while axial movement  of  the  sleeve  relative  to  the bearing ring is inhibited.

Title: Low nox burner
Inventor: FLANAGAN PAUL
IPC: F23D14/26
Filed: 1991-10-23
Abstract: A  method  of  operating  a  burner  to  reduce  the NOx emissions produced  thereby  is  disclosed.  Air and gas are premixed  in  a   manner such  that  excess air exists in the resulting   mixture  and  the  velocity  of  the  mixture  is increased  as  it  passes  through the burner.  By increasing the  velocity  of  the  air/gas mixture, the "residence time" associated  with  the  formation  of  the flame is decreased, i.e.,  the  combustion  gases are in the reaction zone of the flame  for  a  significantly shorter period of time, reducing the  production  of  NOx.  In order to prevent the flame from "lifting-off"  the burner because of the high velocity of the air/gas  mixture, flame stabilizing devices or techniques are utilized   resulting   in  a  high  heat  flux  and  low  NOx production.
