Abstract: A voice signal transmission system reduces the amount of an increase in calculation, while suppressing possible deterioration of the performance, by an expansion in the distribution of a voice parameter representative of an envelope of a voice spectrum when an input voice having a plurality of frequency characteristics is treated simultaneously. A discrimination circuit discriminates, based on a voice parameter extracted by a spectrum parameter extraction circuit, another voice parameter obtained by quantization of the extracted voice parameter by a first quantization circuit and a further voice parameter obtained by quantization of the extracted audio parameter by a second quantization circuit, which one of either a third quantization circuit designed corresponding to the first guantization circuit or a fourth quantization circuit designed corresponding to the second quantization circuit should be used. Then, in accordance with a result of the discrimination, the third quantization circuit or the fourth quantization circuit quantizes a quantization error of the corresponding first guantization circuit or second quantization circuit as an error vector. On the reception side, the error vector is dequantized in accordance with the discrimination.

IPC: F27B3/22
Filed: 1990-12-19
Abstract: An  improved  industrial  furnace  employing a new  and unique heat transfer arrangement is disclosed.  The furnace is a closed end cylindrical chamber with a circular, concen-trically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into 8 heat treat chamber containing the work. The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing.   Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the beat treat chamber at slow speed.  Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good  heat  transfer  therewith.   The under-pressure opening causes the heated wind to contact the work before it is drawn into the under-pressure opening for recirculation. An incineration track is provided in the furnace insulation for incinerating the furnace flue products while also heat-ing the wind mass.

Filed: 1996-04-23
Abstract: A method for automatically updating a central LNP database shared among a plurality of central office switches is instigated when a message from a provisioning system to add a directory number is received by a central office switch. In response to the message, a first central office switch accesses the central LNP database by sending a query message which contains the directory number to be added and routing data specific to the central office switch. Responsive to the query message, the LNP  database searches for the directory number received from the first central office switch. If the directory number is found, the database queries a second central office switch to determine if the directory number is in use. If the number is in use, the central LNP database returns a failure message to the first central office switch. If the directory number is not found in the central LNP database or if the directory number is not being used by the second central office switch, the directory number and routing data received from the first central office switch and a transaction entry are added to a table corresponding to the first central office switch in the database.

Title: Method for extracting bitumen from tar sands
Inventor: DAVIS ROBERT MICHAEL
IPC: C10G1/04
Filed: 1996-06-26
Abstract: A method for extracting bitumen from crushed mined tar sands comprising contacting the mined tar sands with a solvent in the presence of sonic energy in the frequency range of 0.5 to 2.0 kHz. Specifically, a solvent is first mixed with crushed mined tar sands and the mixture is then formed into a slurry of tar sand suspended in the solvent. Thereafter the tar sand slurry is injected into the top of a vertically disposed, substantially rectangular shaped, hollow acoustic chamber of uniform cross-section. Fresh solvent is injected into the bottom of the acoustic chamber and flows upwardly through the cell. The fresh solvent is injected into the bottom of the acoustic chamber at a rate low enough whereby the tar sand particles in the slurry fall by gravity through the upwardly flowing solvent. The tar sand particles and solvent in the acoustic chamber are subjected to acoustic energy in the frequency range of 0.5 to 2.0 kHz whereby the bitumen is separated from the tar sand and dissolved by the upwardly flowing solvent without cavitation of the solvent. The bitumen dissolved in the solvent is recovered from the top of the acoustic chamber and transferred by pipeline to an off-site refinery. The bitumen-extracted sand particles recovered from the bottom of the acoustic chamber may be recycled to the top of the acoustic chamber to recover additional bitumen after injection of the slurry has been discontinued.

Patent CA-2184044-A1 (CA)
Inventor: BRANCONNIER RENE JOSEPH
IPC: C05F17/00
Filed: 1996-08-23
Abstract: A thermophilic, aerobic fermentation process is disclosed for conversion of a wide variety of organic waste materials to useful end products. The fermentation process is initiated over a period of from about 2 to 6 days by application of external heat to an uninoculated, oxygenated aqueous mixture of the waste material, and thus utilizes thermophilic microorganisms naturally present in the waste material to initiate the fermentation. After initiation of an active fermentation, additional amounts of waste material are added to the fermenting mixture on a continuous or intermittent basis to maintain the fermentation in an active state. Therefore, the process can be conducted on a continuous or semi-continuous basis, requiring about 24 to 48 hours for waste to be completely converted to end product. The process is capable of being operated over a wide pH range and can ferment acidic waste materials without the need for pH adjustment. The process converts waste matter such as food waste and fecal matter into a protein enriched end product suitable for use as an animal feed, feed supplement or fertilizer, fertilizer ingredient, soil amendment or soil conditioner free of pathogens, biological contaminants and chemical contaminants such as antibiotics.
