Patent CA-2255397-A1 (CA)
Title: Fault interrupter and operating mechanism therefor
Inventor: LIN CHESTER H
IPC: H01H3/30
Filed: 1998-12-09
Abstract: A fault interrupter is provided that includes a high-speed disconnect in series with an interrupter wherein the circuit opening is via the interrupter and the circuit making is via the disconnect. A stored energy disconnect operating mechanism operates the disconnect between ground, open and closed positions and also charges the interrupter mechanism during a slow opening of the disconnect without fully charging the disconnect operating mechanism. Thus, the required operating forces to open the disconnect and charge the interrupter mechanism are reduced. During a manual opening, the disconnect operating mechanism trips open the interrupter, then only partially charges to begin opening the disconnect before releasing the stored energy. Continued operation of the disconnect operating mechanism slowly drives the disconnect open while charging the interrupter mechanism and closing the interrupter. The interrupter mechanism remains charged during operation of the disconnect between the open and ground positions by the disconnect operating mechanism.

Title: A crystalline substance of cefditoren pivoxyl and the production of the same
Inventor: YAMAMOTO YUICHI
IPC: A61P31/04
Filed: 1997-09-19
Abstract: As a novel substance is provided such a new, crystalline substance of Cefditoren pivoxil which has a high purity and an enhanced thermal stability on storage. This crystalline Cefditoren pivoxil may be prepared by a process comprising a step of dissolving amorphous substance of Cefditoren pivoxil in an anhydrous, first organic solvent capable of dissolving said amorphous substance well therein, and steps of replacing the first organic solvent component of the resulting solution by an anhydrous alkanol of 1 to 5 carbon atoms as a second organic solvent, in such a manner that the firstly prepared solution of Cefditoren pivoxil in the first organic solvent is mixed with a volume of the alkanol and then is concentrated below 15°C under reduced pressure, and so on. Thereby, the process proceeds so as to produce a solution containing 50 mg/ml to 250 mg/ml of Cefditoren pivoxil dissolved in the alkanol alone.      From the latter solution, crystals of Cefditoren pivoxil are induced to deposit by addition of water at a temperature of 0 - 10°C. The resulting admixture of the concentrated solution of Cefditoren pivoxil in alkanol with added water and the deposited Cefditoren pivoxil is then agitated 10°C or below, to effect a complete crystallization of Cefditoren pivoxil .

Title: Mobile satellite system/terrestrial wireless system interworking techniques
Inventor: KIM WON S
IPC: G01S19/06
Filed: 1999-04-14
Abstract: Methods for switching a mobile between operation in an mobile satellite system mode and a terrestrial wireless mode. When operating in the terrestrial wireless mode, the mobile terminal will initiate an attempt to switch into the MSS mode when it nears the boundary of the coverage area for a terrestrial wireless system to which it is registered. Conversely, a mobile terminal operating in the MSS mode will regularly attempt to switch into the terrestrial wireless mode. For both, a switch between modes is contingent on the mobile terminal identifying a suitable system for registration therewith upon completing the switch between modes. The criteria for identifying a suitable system for selection purposes include the following: (1) the selected system is available, i.e., the mobile terminal is physically located within a coverage area for the selected system; (2) the mobile terminal is compatible with the selected system; and (3) the selected system is willing to accept the mobile terminal. If multiple systems meet these criteria, the mobile terminal will utilize a stored list of preferred systems to select therefrom. When switching into the terrestrial wireless mode, the MSS system provides the mobile terminal with switch-over information for the underlying terrestrial wireless systems and, when switching into the MSS mode, the terrestrial wireless system provides the mobile terminal with switch-over information for the overlying MSS systems.
