Abstract: A connector is provided for joining two upstream exhaust pipes  with  a  downstream  exhaust  pipe  and  for  substantially offsetting any difference in length that may exist in the upstream exhaust pipes.  The connector includes first and second external shells that are secured on opposite respective sides of an internal divider plate.  The external shells and internal plates cooperate to define unequal travel lengths within the connector to offset the unequal travel lengths of the upstream exhaust pipes leading to the connector.   The two separate exhaust flows with travel lengths equalized by the connector converge with one another into a chamber defined by the connector, and exit from the connector through an outlet.  Expansion of the converging exhaust gas streams into the chamber contributes to acoustical tuning of the exhaust system.          The equal lengths of the respective exhaust gas streams also facilitates acoustical tuning performed by a downstream muffler.

Patent CA-2135572-C (CA)
Inventor: TROTTIER RICK
IPC: B28D1/12

Granted: 2000-09-26
Abstract: Conventional self propelled saw cutting machines utilize air cooled transversely mounted, internal combustion engines. The engine drives a rotatable circular saw blade through a series of pulleys or chain drives. Since the saw is driven at substantially ninety degrees to the engine output shaft this places a considerable side loading on the crankshaft and bearings. In addition the air intake of the engine is in line with and rearward of the saw blade and thus contaminants from the saw cut are drawn into the engine. The method and apparatus of the present inven-tion eliminates both problems by mounting the engine "in-line" with the vehicle frame rather than transversely. This significantly reduces the likelihood of saw cut contaminants entering the engine air intake. A differential assembly is coupled to the output shaft of the engine and, through a pulley system, drives a rotatable axle shaft to which is coupled the saw blade. Mounting the engine "in-line" with the frame opens the possibility of using diesel engines to power the vehicle without increasing the vehicle width and with no loss in maneuverability.

Title: Muting apparatus for a compressed audio/video signal receiver
Inventor: LANKFORD DOUGLAS EDWARD
IPC: H04N7/52
Filed: 1995-04-13
Granted: 2004-12-07
Abstract: A compressed audio/video, A/V, receiver provides A/V component timing reference signals (PTS's) coincident with reproduction of associated decompressed component signals. Synchronization apparatus generates a function of the difference of occurring component audio and video PTS's. This function, which is indicative of relative audio and video synchronization, is compared with a predetermined threshold value, and a mute control signal is generated when the threshold is exceeded. Muting circuitry, responsive to the control signal disables audio reproduction when the reproduced audio and video component signal timing deviate from mutual synchronization.

Abstract: A plurality of methods for achieving the soft or softer handoff process such that the performance of a system is improved. A first method is based on de-laying the softer handoff process. A second method is based on reducing the power of transmissions from the sector having the weakest signal strength. A third method is based on eliminating transmissions from the sector having the weakest signal strength. A fourth method adds a new base station or sector only when the mobile unit is in need of additional power to operate properly. In all four methods, re-verse link demodulation in each sector may continue with or without the transmission of the forward link. In all four methods the operation could be based on the signal strength of the reverse link signal or the forward link. It is also possible to combine two or more of these methods to create a hybrid method.

Granted: 2001-02-13
Abstract: A system in which a private base station supports the registering of multiple mobile stations and generates a personalized call delivery feature for each registered mobile station is provided. Each mobile station registers separately with the base station when within communication range of the base station. When registration of a mobile station with a private base station is performed, the private base station generates a local unique address for each one of the multiple mobile stations registering with the private base station. This unique address for a registered particular mobile station is also sent to the private base station location register. When the private base station receives an incoming call for a particular one of the mobile stations, this local unique address associated with the particular portable station is provided by the base station location register as part of the incoming call information also received by the base station thereby allowing the base station to distinctively alert the particular mobile station. By obtaining a local unique address for each of the mobile stations, the private base station is also able to advantageously offer various intelligent features which are personalized according to customer needs. For example, a calling party may have his or her name displayed on the reached mobile station for the convenience of the user at this mobile station.

Title: Method of treating waste water to remove harmful ion by coagulating sedimentation
Inventor: IKEDA KENICHI
IPC: C02F1/52
Filed: 1996-07-30
Granted: 2001-05-29
Abstract: The invention relates to the treatment of waste water containing a harmful ion such as a heavy metal ion or fluorine ion by the coagulating sedimentation method using an inorganic coagulant such as an iron compound or an aluminum compound. After separating treated water from the sediment (sludge) in which the harmful ion is incorporated in insoluble form, the pH of a mixture of the sediment and water is suitably adjusted to cause elution of the harmful ion from the sediment. Then the sediment is separated from the eluate and reused as an inorganic coagulant. By reusing the sediment in this manner, the waste water treatment is accomplished without producing a large quantity of sludge and the consumption of inorganic coagulant and auxiliary chemicals can be greatly reduced, while the concentration of the harmful ion in the treated water becomes sufficiently low.

Abstract: System and method for securely backing up and reliably retrieving vault data in a metering system that includes a host processor operatively coupled to a vault. Whenever a transaction is completed by the vault, the vault cryptographically signs the vault data, including ascending register, descending register and piece count and sends the cryptographically signed vault data to the host processor where it is stored in a data file assigned to the vault. Each storage of the cryptographically signed vault data is indexed to create a historical log of vault transactions. If the vault is lost or damaged so that vault data cannot be retrieved from the vault, the cryptographically signed vault data is retrieved from the host processor data file and verified.
