Patent CA-2167250-A1 (CA)
Inventor: BOLLAERT MATTHEW C
IPC: B60R21/16
Filed: 1996-01-15
Abstract: An inflatable vehicle occupant restraint (12) includes a first fabric panel (60), a second fabric panel (62), and a seam (64) at which the fabric panels (60,62) are fastened to each other.  The restraint (12) further includes a vent opening (128) which interrupts the seam (64) to direct inflation fluid to exit the restraint (12) between the fabric panels (60,62).  The restraint (12) is inflated between a vehicle seat (16) and an adjacent vehicle door (18) upon the occurrence of a side impact collision, and protects an occupant of the seat (16) from being forcefully struck by the door (18).  The vent opening (128) directs the inflation fluid to exit the restraint (12) in a direction which is perpendicular to the direction in which the door (18) is moved toward the seat (16) by the side impact collision.  As a result, the flow of inflation fluid which is directed from the restraint (12) through the vent opening (128) is directed away from the occupant and is not blocked or impeded substantially by the seat (16) or the door (18).

Title: Mechanism for controllably enabling test set to assert off-hook condition on telephone line in dependence upon detection of prescribed voltage level and absence of data traffic
Inventor: WALANCE ROBERT B
IPC: H04M3/30
Filed: 1996-02-29
Abstract: The possibility of corrupting digital data traffic carried by a data line (11, 12) (powered or unpowered), by the connection of a telephone test set to the data line (11,12) is effectively prevented by augmenting the telephone test set with a mechanism that prevents the test set from asserting an OFF-HOOK condition on the line, unless it has been determined that each of two conditions are satisfied. These conditions are: 1- that no digital data traffic is being carried by the line (11, 12); and 2- that the electrical voltage condition of the line (11,12) satisfies a prescribed minimum voltage level criterion. If either of these conditions is notsatisfied, a switch circuit installed in the test set's connection path to the line is maintained in a default, open condition, so that it is effectively impossible for the line to be presented with an OFF-HOOK condition through operation of the test set. This default condition remains in effect until both criterion are fulfilled. As a further safety precaution, should the line to which the test set is connected be determined to be carrying digital data traffic, the invention causes an audible alert tone to be generated as a warning signal to the craftsperson.

Title: Fiber optic splice tray hinge adapter
Inventor: BUREK DENIS EDWARD
IPC: G02B6/44
Filed: 1996-04-26
Abstract: A hinge adapter mounts to a fiber optic splice tray, such as the Keptel LL-2400? splice tray, and provides a hinging capability to these splice trays. The hinge adapters have a U-shaped member mounted at each corner of the splice tray. The U-shaped member has a central portion having a pair of arms depending therefrom, with the distal ends of the arms having an aperture and the ends of the central portion having a protrusion. When stacking the splice trays, the apertures formed in the arms of one hinge adapter receive protrusions in the central portion of another hinge adapter. When the hinge adapters on one side of a desired splice tray are separated from the hinge adapters above that splice tray, an installer or lineman can pivot the upper splice trays away from the desired tray and readily gain access to the desired splice tray. The U-shaped members are mounted to a side of the splice tray by brackets which are inserted into an area of the splice trays. The U-shaped members, the brackets, and a flexible band which joins two brackets are molded out of a flexible material, such as polycarbonate.

Title: Method for production of sodium bicarbonate, sodium carbonate and ammonium sulfate from sodium sulfate
Inventor: HALLDORSON JAKE
IPC: C01D7/18
Filed: 1996-06-21
Abstract: A process for producing sodium bicarbonate and sodium carbonate. The process includes reacting within a reactor sodium sulfate in aqueous solution with ammonia and carbon dioxide to precipitate sodium bicarbonate and form a first mother liquor. The sodium bicarbonate is separated and dried to produce sodium bicarbonate product. Alternatively, the sodium bicarbonate may be calcined to convert it to sodium carbonate. The first mother liquor may be evaporated to precipitate unreacted sodium sulfate, with the formation of a second mother liquor. The second mother liquor may be cooled to precipitate a double salt of sodium sulfate/ammonium sulfate and water. A third mother liquor is formed from this process. The latter-mentioned liquor from the precipitation of the double salt is evaporated to precipitate a substantial pure ammonium sulfate in a purity of greater than approximately 75 wt %. A fourth mother liquor is formed. The double salt is added to the first mother liquor from the precipitation of sodium bicarbonate prior to the evaporation step and the fourth mother liquor is added to the second mother liquor from the evaporation to precipitate unreacted sodium sulfate.
