Patent CA-2221799-A1 (CA)
Inventor: FINK MICHAEL
IPC: B60R21/26
Filed: 1997-03-21
Abstract: A valve mechanism (40) for controlling the release of gas (52) from a pressure vessel (50) into an airbag system is disclosed. When a collision occurs, gas (52) is initially released from a pressure vessel (50). The gas (52) travels through a valve mechanism (40) which regulates the volume of the gas (52) flowing through the valve from the pressure vessel (50) into an inflatable vehicle occupant restraint (30). When inflated, the vehicle occupant restraint (30) restrains an occupant of a vehicule during a collision. By controlling the gas flow into the airbag (30) at the appropriate times, the valve achieves the desired bag energy absorbing characteristics for each unique crash situation. The valve uses pilot pressure and actuating means (86) to control the flow by controlling the cross-sectional area of the gas flow path through the valve system (40).

Title: Method for laser mediated tissue welding with enhanced strength
Inventor: POPPAS DIX P
IPC: A61K38/00
Filed: 1996-06-03
Abstract: Methods for tissue welding using solders incorporating biologically active agents, such as growth factors or hemostatic agents, have been developed.  Improved solder compositions have also been defined, yielding greater bursting strength as a function of protein concentration, and through the use of protein unfolding prior to laser-mediated denaturation and coupling. A method for repair of fistulas has been discovered, using water as a chromophore, in combination with solder concentration, to form columns to fill defects where tissue apposition is not possible. Methods have also been adapted for use with other forms of directed energy, including bipolar electrosurgery and light.  Examples demonstrate increased strength of repairs by incorporation of growth factors into solders, alone and as a function of solder concentration.  Increased adhesion is obtained through prevention of bleeding by incorporation of hemostatic agents such as thrombin or epinephrine, a vasoconstrictor.

Title: Process for making shaped copper articles
Inventor: ENOS SUSAN S
IPC: C25D1/04
Filed: 1996-11-12
Abstract: This invention relates to a process for making shaped copper articles directly from a copper-bearing material wherein a copper bearing material (10) is contacted with an effective amount of an aqueous leaching solution (40) to form a copper-rich aqueous solution which is contacted with a water-insoluble extractant in which copper ions are transferred from the former to the latter (20, 18) forming a copper-rich extractant (51) and a copper-depleated aqueous solution (73) which are separated followed by contacting the copper-rich extractant with an aqueous stripping solution (60) transferring the copper ions from the former to the latter thereby creating a copper-rich aqueous stripping solution which is piped to an electrowinning cell (124) wherein the copper ions contained in the solution are deposited as copper powder on the cathodes (126), followed by the removal of the copper powder from the cathode (129), followed by extruding, forging, or molding the copper powder (154) to produce a shaped copper article.

Title: Condenser for binary/polynary condensation
Inventor: VOLKS GUENTER
IPC: F28F9/013
Filed: 1997-12-18
Abstract: A dephlegmation condenser  for binary/polynary condensation of a vapor mixture is arranged upright. It has tubes (4) through which the coolant flows, an inlet connection  (1)  arranged  in  the  top  region  of  the coolant  tubes  and  intended  for  the  mixture  to  be condensed,  and a collecting space  (2)  arranged below the coolant tubes  (4)  and intended for the condensate to  be  drawn  off.  The  inlet  connection  (1)  and  the collecting space (2) are connected to one another via a condenser shell (3) encasing the tubes (4). The coolant is directed in pure counterflow to the mixture in the predominant part of the condensation space.       The  vapor-side,   smooth  temperature  profile achieved is a consequence of the segregation during the condensation.  A mixture  which  is  enriched  with  the higher-boiling component  of  the mixture  condenses at the start of the condensation section, whereas another mixture which is enriched with the lower-boiling compo-nent of the mixture condenses out at the end of the condensation section.

Title: Wireless communications method utilizing control channels
Inventor: LADUE CHRISTOPH K
IPC: H04M11/00
Filed: 1995-08-04
Abstract: A method for use with wireless communication systems operating over cellular control channel communication bands, paging communication bands, and satellite communication bands. A transceiver transmits specialized communication protocols that contain specialized data (100) to cell-sites and mobile switching centers. The data is packaged so it does not disrupt normal voice and data traffic. The application data is scanned and recognized at the cell-site and mobile switching center and routed to central monitoring stations via the public switched telephone network. Application specific data is processed and application specific responses are read by computers (116). The central monitoring station transmits command and instruction data to an application specific transceiver that contains circuitry to receive the application specific messaging from cellular forward control channels, paging bands, and satellite bands. The transceiver responds to received commands by transmitting specialized protocols over wireless communication system control channels.  Specialized control channel protocols contain global positioning coordinance data, paging acknowledgment data, security status data, motor vehicle location and status data, and other application specific data.

Title: Determination of aqueous fluid surfactant concentration
Inventor: ERNST JOSEPH M
IPC: G01N31/22
Filed: 1997-08-04
Abstract: A single-phase method for quantitatively measuring the anionic surfacatant content of an aqueous machining fluid is provided. The method is carried out at a pH value of from about 1.5 to about 3.0 and from about 9.5 to about 10.6 and involves the addition of an excess of a standardized aqueous solution of 1,3-didecyl-2-methylimidazolium chloride to the sample of aqueous machining fluid and then back titrating the excess 1,3-didecyl-2-methylimidazolium chloride with a standardized aqueous solution of polyvinylsulfuric acid potassium salt in the presence of toluidine blue indicator. Values of the amount of 1,3-didecyl-2-methylimidazolium chloride amount corresponding to anionic surfacatant concentration are produced by conducting the method using a series of stantard aqueous solutions containing anionic surfactant at known concentrations. These values are used to quantitatively determine the anionic surfactant content of a sample of aqueous machining fluid of unknown anionic surfactant concentration from measured values of 1,3-didecyl-2-methylimidazolium chloride obtained according to the method using the sample.
