Patent CA-2224348-A1 (CA)
Title: Air impingement oven
Inventor: MURGEL LEONARDO P
IPC: A23L5/10
Filed: 1997-12-10
Abstract: An oven for continuous cooking of products carried upon a open mesh wire conveyor provides the impingement of a cooking vapor from air discharge structure having ports arrayed above and below the conveyor.  The discharge ports extend laterally of the conveyor and communicate with upper and lower plenums each charged by blower fans which draw cooking vapor from low pressure corridors alongside the product conveyor.  Gas, electric or thermo fluid heaters are disposed in the corridors.  The discharge ports are in slot form disposed about the apex of a Vee shaped riser spaced from the adjacent riser to provide a low pressure flow channel communicating with the corridors giving a rapid velocity change of the cooking vapor from turbulent to a less turbulent flow.  The distance for vapor travel between the upper discharge ports and the product carrying conveyor is variable.  Temperature and moisture content of the process vapor can be changed to suit cooking conditions.

Title: A method and system for mail piece production utilizing a data center and inter-related communication networks
Inventor: OH JE H
IPC: G07B17/00
Filed: 1997-12-22
Abstract: The invention is a method for producing a finished mail piece. The method allows a system user to select at a first node, a plurality of characteristics which define a mailing. These characteristics include selection of a document to be printed at a terminal node and a list of addresses to which the printed document will be sent. Once selections have been made, the print job is transmitted to a terminal node which comprises a data processor, an envelope printer, and a document printer among other elements. The document printer will print the document in accordance with the characteristics selected at the first node; and, the envelope printer will print addresses from the address list to corresponding envelopes. Once the document has been printed, it is inserted into the envelope by inserting means to form an unfinished mail piece. The unfinished mail piece is sealed and then franked with appropriate postage in order to form a finished mail piece. The mail piece is then placed into a mail stream for delivery to the destination address. A receipt indicative of the print job and delivery into the mail stream may be optionally generated by the terminal node and transmitted to the first node. Several nodal layers can be created such that the first node can transmit the print job to a second node which can further transfer the print job to subsequent nodes for printing and routing.

Title: Photo signal amplification transmission system
Inventor: MARUYAMA NAOKI
IPC: H04B10/29
Filed: 1998-04-21
Abstract: In a conventional photo signal amplification transmission system, since control is performed to make constant an output power, total output powers of all wavelengths are made constant when a multi-wavelength transmission is made.          An output power of one wavelength is decreased and deviated from an optimum power.  To solve the problem, a transmission photo amplifier 3, a relay photo amplifier 4 and a receiving photo  amplifier  5  are  provided with  wavelength  number information management sections 11, 12 and 13, respectively.    An amplifying means is controlled in accordance with the number of wavelengths of the multi-wavelength signal which is obtained by the wavelength number information management sections.   The wavelength number  information management sections 11 to 13 multiplex a wavelength number information signal onto an optical fiber cable 6 and renews the signal.

Title: Method of enhancing call processing in a number portability environment
Inventor: TEWANI KAMLESH T
IPC: H04Q3/00
Filed: 1998-05-11
Abstract: METHOD OF ENHANCING CALL PROCESSING IN A NUMBER              PORTABILITY ENVIRONMENT     A method reduces the number of queries generated to a number portability database.  The number portable communication system includes a local cache associated with the switching office or facility responsible for identifying and controlling the routing of calls to portable numbers (NPA-NXXs ) . By including the cache and only generating a request to the number portability database when the cache either does not contain LRN response information or if a call attempted based on LRN response information in the cache fails, the total number of queries to the number portability database are reduced.  This reduces query traffic as well as speeds up the processing of calls able to use cached information, regardless of whether or not the called number is ported.
