Patent CA-2190646-A1 (CA)
Inventor: BUBEL ALEXANDER
IPC: B29C45/50
Filed: 1996-11-18
Abstract: A process and apparatus for applying an oscillating force to a molten material. The apparatus includes a barrel in communication with a hopper for receiving a flow of moldable material. A screw conveyor is rotatable and axially reciprocatable within the barrel. At least one conveyor flight is formed on the screw conveyor for conveying and compressing the moldable material. Rotation and reciprocation of the screw conveyor forces the material to flow out of the barrel and along a conduit in a mold assembly. The conduit communicates with a mold cavity. A controller controls the rotation and reciprocation of the screw conveyor. The controller reciprocates the screw conveyor toward and away from the mold during filling of the mold cavity inducing a shearing of the material. Each reciprocation of the screw conveyor translates the screw conveyor closer toward the mold cavity. A method is also disclosed which includes dispensing a moldable material into an barrel. Rotating a screw conveyor about its longitudinal axis for conveying the moldable material. Accumulating a predetermined amount of material. Translating the screw conveyor along its longitudinal axis toward a mold to a first location, thereby forcing a portion of the accumulated material to flow into a mold cavity. Translating the screw conveyor away from the mold. Then translating the screw conveyor again toward the mold to a second location, thereby forcing additional accumulated material to flow into the mold cavity, the second location being closer to the mold than the first location.

IPC: H04J14/02
Filed: 1997-02-25
Abstract: A dispersion tolerant OC-192 optical transceiver includes the circuitry for implementing the method of reducing optical signal disposition in a high data rate data stream that travels on an optical fiber communications system.  The circuitry includes circuitry for partitioning the high data rate data stream into a plurality of lower data rate data streams.

Title: Thin film actuated mirror array for use in an optical projection system
Inventor: YOON DONG SEON
IPC: G02B26/08
Filed: 1995-07-11

Patent CA-2204483-A1 (CA)
Title: Creating and using an adaptable multiple-contact transaction object
Inventor: OWEN JAMES E
IPC: H04L12/24
Filed: 1997-05-05
Abstract: An object is dynamically created which contains all of the information relating to connections established during a transaction. This object also contains information and/or pointers to information which was used in a communication during the transaction. The object further contains tests for triggering events. When a triggering event occurs the connections are automatically re-established so that a further communication relating to a transaction may be accomplished with excellent efficiency and without any duplication of effort by an agent (including an electronic agent or device) to locate information which was located during the previous communication. The test is administered by a business process mediator, which invokes a business task mediator, which may invoke multiple lesser task mediators, each of which may invoke additional lesser task mediators. Task mediators perform functions ranging from a lower level function, such as detecting a dial tone, to a higher level function, such as connecting a customer to an agent and providing all relevant customer information to the agent. The calling of a higher level task mediator automatically invokes the calling of the lesser, lower level task mediators necessary to accomplish the specified task. Thus, the various task mediators automatically reconstruct the connections necessary to accomplish the further communications. The communications may be by telephone, conventional mail, facsimile, electronic mail, internet, wireless, satellite, cable TV, radio, or other means and may involve audio, video, text, facsimile or electronic mail documents, pictures, spreadsheets, etc.
Patent CA-2206529-A1 (CA)
Inventor: WALSH DENNIS EDWARD
IPC: C07C15/073
Filed: 1995-12-04
Abstract: The present invention relates to a process for preparing ethylbenzene using liquid phase alkylation and vapor phase transalkylation. The liquid phase alkylation reaction may be catalyzed by an acidic solid oxide, such as MCM-22, MCM-49 and MCM-56. The vapor phase transalkylation may be catalyzed by a medium-pore size zeolite such as ZSM-5.  The process may be run continuously with the continuous introduction of fresh benzene feed containing at least 500 ppm of nonbenzene hydrocarbon impurities. The combined ethylbenzene product of these alkylation and transalkylation reactions has very low levels of impurities including xylene, hydrocarbons having 7 or less carbon atoms and hydrocarbons having 9 or more carbon atoms.
Patent CA-2209130-A1 (CA)
Title: Method of manufacturing a plastic camshaft with a tubular metal insert
Inventor: BUCHHOLZ BRIAN S
IPC: B29C45/14
Filed: 1997-06-27
Abstract: A method of manufacturing a plastic camshaft having a tubular metal insert using a die assembly having a pair of aligned pins.  The tubular metal insert is cut to a length slightly shorter than the length of the finished camshaft and is placed on one of the pins.  The second pin is then inserted into the opposite end of the tubular metal insert during the closing of the die assembly. The pins properly align the metal insert within the mold cavity of the die assembly during injection of a surrounding plastic material which forms the remainder of the camshaft.  The pins also axially compress the tubular metal insert and have tapered shoulders which bear against and slightly deform or flare the end regions of the insert.  The flared ends of the tubular metal insert tightly engage the pins and prevent the formation of flash within the hollow interior of the tubular metal insert.  By cutting the inserts to a length which is shorter than the total length of the camshaft, imprecision in the cutting of the insert does not result in the formation of flash adjacent the annular ends of insert.  This method permits the tubular metal insert to be properly located within the mold and prevent the formation of flash during injection of molten plastic without requiring the metal insert to be precision ground.

Title: Biogas-driven generator set
Inventor: KING JAMES L
IPC: F02B43/00
Filed: 1996-01-02
Abstract: A generator powered by an internal combustion engine is fueled from a source of biogas. A pump boosts the pressure of the biogas, and a regulator controls the biogas pressure supplied to the fuel intake of the engine carburetor. Acid-neutralizing oil is injected into the biogas stream at the intake of the pump to protect the engine from corrosion due to acidic constituents in the biogas.  In a preferred embodiment the biogas flows through a filter which removes hydrogen sulfide and mercaptans and through a coalescer to remove water vapor.  A regulator controls the biogas pressure supplied to the fuel intake of the engine, carburetor, and acid-neutralizing oil is injected into the engine intake each time the engine is shut down to protect the engine from acidic constituents in the biogas.
