IPC: H04M3/42
Filed: 1996-01-19
Abstract: A method and apparatus for prioritizing telephone calls that allow the caller to specify priority criteria relating to a call and the recipient to specify priority criteria relating to the treatment of incoming calls. The caller designates a priority of the call. The caller's satisfied priority is stored in a database in the telephone service provider's network, is retrieved from the database when the caller placer a call, and is transmitted with the call through the telephone network. The call recipient designates specified priority criteria for incoming calls.      The call recipient's specified priority criteria are stored in a database and retrieved from the database in response to incoming calls. The treatment of a call, i.e. connection, termination or redirection, is based on comparison of the caller' s priority and t:he call recipient' s specified priority criteria.

Title: Method and apparatus for testing of extended isdn bri service
Inventor: EMERSON EARL A
IPC: H04M3/22
Filed: 1996-06-03
Abstract: An enhanced ISDN-DP transmission device of the present invention allows for testing of ISDN-protocol communication paths using an existing DDS-protocol test infrastructure. The ISDN-DP unit receives a DDS test command and determines whether the command was intended for the immediate receiving unit or a tandem unit.  If the command is intended for the immediate ISDN-DP unit, the unit processes the command.  If the command is intended for another ISDN device in the transmission path, the ISDN-DP converts the DDS-protocol command to an ISDN-protocol command and transmits the converted ISDN command to an adjacent tandem ISDN device in the communication path in an upstream or downstream direction.  After the test path is enabled, loopback testing is available on all available ISDN bandwidth, including the B1, B2 and D+ channels, from a DDS-protocol test set. DDS-protocol test access is available from a plurality of locations including: multiplexed bit stream access at a digital crossconnect switch; metallic access at a DS0 interface; faceplate access at the ISDN-DP unit.

Title: Purification of natural gas
Inventor: EIMER DAG ARNE
IPC: B01D53/26
Filed: 1994-12-23
Abstract: The present invention relates to a process for the purification of natural gas to make it comply with gas or pipeline specifications comprising that the gas has a dew point between 0 ~C and -18 ~C and a H2S content below 4 ppm by volume. H2S and water are removed simultaneously from the natural gas in an absorption column where the gas is contacted with an amine-glycol solution. The glycol solution is then heated, flashed and then brought in contact with a stripping gas to be freed of the water and H2S, whereupon the stripping gas containing removed H2S and water is combusted with air whereby the H2S is converted to SO2 which subsequently is absorbed in a contact unit to which sea water is supplied and brought in contact with the exhaust gas from the combustion unit. The absorption solution is preferably a mixture of a primary and/or secondary alkanolamine in mono-, di-, and/or triethylene glycol.

Title: Flexible sign-post
Inventor: CLARKE ERNIE
IPC: E01F9/627
Filed: 1996-11-18
Abstract: A Flexible Sign-Post device that is suitable for holding signs along streets, roadways and automobile parking lots. The flexible sign-post is comprised of a lower base plate that is permanently anchored to a hard top ground surface, such as asphalt or concrete. The lower base plate supports a resilient helical spring, the lower end of the helical spring being mounted to the base plate and the upper end of the helical spring, being affixed to a cylindrical retaining member of sufficient height as to be approximately on the same plane as the average automobile bumper and also capable of receiving a shear pin. A cylindrical sign post, being of the same diameter as the cylindrical retaining member is descended over the shear pin, that is protruding upwards from within the cylindrical retaining member and secured to it by way of screws. In another embodiment, a tapered spike-like attachment plate can be secured to the base plate allowing the flexible sign-post to be anchored into firmly packed ground soils such as landscaped areas or locations where a hard top ground surface is not available. The sign-post will yield when impacted by a vehicle, however, the resiliency of the helical spring will allow the sign-post to be returned to its original vertical orientation. When the sign-post is overstressed, by vehicular impact or drive over, the shear pin will snap, causing the sign to fall freely to the ground, thus inflicting little or no damage to both vehicle and sign- post. Repairs to the sign-post can be easily and inexpensively made by replacing the shear pin with a new unit and reinstalling and securing the original sign-post.

Patent CA-2192864-A1 (CA)
Title: Inert atmosphere soldering apparatus
Inventor: SUND WILLIAM
IPC: B23K1/08
Filed: 1996-12-13
Abstract: In soldering devices such as printed circuit boards it may be desirable to expose only those portions of the board having terminals to be soldered to the molten solder. To this end an inert atmosphere spot soldering process and apparatus uses pockets arranged to match the arrangement of the terminals to be soldered. The cups are filled to overflowing with liquid solder and provided with an enveloping flow of hot inert gas. The terminals and their surrounding area are exposed to the hot inert gas for a period sufficient to drive off substantially all  volatile liquids and the terminals are then immersed in the solder to a depth determined by the meniscus of the liquid solder in the pockets without permitting the board to contact the pockets. After immersion, the terminals are raised gently, non-parallel to the solder surface, until they are above the solder and then the flow of inert gas is terminated permitting the solder to solidify. The inert gas may be heated by thermal conduction from the liquid solder.
