Patent CA-2246932-A1 (CA)
Inventor: HOFER HANS-HEBERT
IPC: G01F22/02
Filed: 1998-09-10
Abstract: During the application of a coating material to paper or to cardboard, air inclusions in the coating material can interfere with production in various ways. It is proposed to measure the air inclusion content in a coating material by  taking  samples  of  the  material.  Each  sample  is introduced  at  a predetermined  first  pressure  into  a measurement  cell  which has  a  closed  first volume.  This closed  first  volume  in then reduced to a closed second volume at which a predetermined second pressure that is greater than the first pressure prevails in the measurement cell. The air inclusion content of the coating material can then be  derived  from  the  change  in volume  required  to produce the predetermined pressure change. On the basis of the measured values, degassing equipment can be optimally adjusted.

Patent CA-2251767-A1 (CA)
Inventor: THOMPSON WILLIAM L
IPC: B01D53/38
Filed: 1997-05-08
Abstract: A regenerative thermal oxidizer (H-101) includes a number of heat exchange columns (A, B) topped by a combustion chamber (C-101). Contaminated air is directed into one of the columns and oxidation is completed as the flow passes through the combustion chamber (C-101). From the combustion chamber (C-101), the now clean air flows vertically downward through another column and then is directed via an outlet valve through an outlet manifold and released to atmosphere or recirculated back to the oxidizer (H-101). A combustible fuel is added to the contaminated air prior to its entry into one of the columns. The addition of the combustible fuel is regulated by continuously monitoring the inlet and outlet temperatures (TE-101A, TE-108A), and comparing a difference between these temperatures to a predetermined value. Further control can be achieved by measuring the flow of contaminated air to the oxidizer (H-101) via pressure differential and coordinating that measurement with the temperature differential measurement.

Title: Method and system for using tcap signaling for improved call setup from a virtual switching point
Inventor: GILBERT GORDON J
IPC: H04M3/51
Filed: 1999-05-03
Abstract: A method and system for using TCAP signaling for improved call setup from a virtual switching point are disclosed. In accordance with the method, TCAP signaling is used to enhance call setup from virtual switching points which receive call request messages from calling parties using a facility on a data network such as the Internet. TCAP signaling is used when necessary to determine the availability of the called party telephone. The system includes a Virtual Switching Point (VSP) in a switched telephone network having a connection to a data network such as the Internet. Call requests are received by the VSP from the data network and processed by the VSP to establish a voice connection between the calling party which initiates the call request and a called party number indicated in the call request message. The use of TCAP signaling from the VSP to Switching Points (SPs) which serve the calling party and/or the called party improves efficiency and minimizes common channel signaling. The VSP enabled with TCAP signaling can also be used as an efficient out-dialer for a call center. The advantage is the ability to offer more calling options while improving network use efficiency.

Title: Intelligent hypersensor processing system (ihps)
Inventor: ANTONIADES JOHN A
IPC: G06V20/13
Filed: 1997-04-21
Abstract: The Intelligent Hypersensor Processing System (IHPS) is a system for the rapid detection of small, weak or hidden objects, substances or patterns embedded in complex backgrounds, providing fast adaptive processing for demixing and recognizing patterns or signatures in data provided by certain types of hyper-sensors. IHPS processes by forming a series of pattern vectors through the concatenation of the outputs of multiple sensors (10). Each sensor measures a different attribute of the system being observed, and has a consistant relationship to all other sensors. The data stream from the sensors is entered into a processing system which employs a parallel pipeline architecture.  The data stream is simultaneously sent to two separate processor pipes. The first is the Demixer Module (20), which decomposes each pattern vector into a convex combination of a set of fundamental patterns.      The signature pattern of a weak constituent or unresolved small target is separated from the background patterns which may hide the target. Information detailing the composition of the dimixed data patterns is sent to the Display/Output Module (40) along with information about the fundamental patterns and Filter Vectors.
