Title: Apparatus and method for determining identification and concentration of an atmospheric component
Inventor: WANG DA Y
IPC: G01N27/416
Filed: 1990-12-12
Abstract: IMPROVED APPARATUS AND METHOD FOR DETERMINING IDENTIFICATION AND CONCENTRATION          OF AN ATMOSPHERIC COMPONENT            Abstract Apparatus and method for determining the identity and concentration of one or more components in a test atmosphere having a known concentration of oxygen.   A solid electrolyte oxygen sensor is used, having a first solid electrolyte wall in contact with, and interposed between, a first electrode and a second electrode and a second solid electrolyte wall in contact with,  and interposed between a third electrode  and a fourth electrode.   The second and fourth electrodes are in communication with the test atmosphere.  A partition wall separates the first and third electrodes forming a first chamber bounded by the first wall and the partition wall and a second chamber  bounded by the partition wall and the second wall.   Diffusion limiting means  inhibit gas flow of the gas from the test atmosphere to the first chamber and from the first chamber to the second chamber. A first negative voltage (or positive voltage when then unknown component has a concentration larger than that of a stoichiometric gas mixture) is applied to the first and second electrodes generating a first electrical current on a first electric current plateau.  Simultaneously the EMF across the third and fourth  electrodes is measured. These two numbers are correlated with a table to determine gas component identity and concentration.  Alternatively a first negative voltage is applied to the first and second electrodes  generating  a  first  electrical  current. Simultaneously a second negative voltage is applied to the third and fourth electrodes generating a second electrical current.  The magnitudes of said first and second voltages are in contrast to each other (the first voltages is low and the second voltage is high or vise versa, with their difference kept at least 1000mV).  The second current is measured and is correlated with a figure to determine gas concentration or hydrogen-equivalent gas concentration.

Title: Solid electrolytic fuel cell and method of dissipating heat therein
Inventor: DIETHELM ROLAND
IPC: H01M8/124
Filed: 1991-08-08
Abstract: A battery of solid electrolytic fuel cells is provided with heat conductive temperature equalizing members disposed in alternating relation with electrochemically electrode active structures of the fuel cells. The heat produced by the electrochemical reaction is dissipated by the air which is applied to the fuel cells to provide the oxygen required for the reactions. The transfer of the heat of reaction to the air is largely brought about before the air comes into contact with the electrochemically active structures. The transfer of heat from the electrochemically active structures to the equalizing members occurs mainly by thermal radiation whereas heat is transferred from the equalizing members to the air by heat conduction.

Patent CA-2053441-A1 (CA)
IPC: H04Q11/04
Filed: 1991-10-17
Abstract: A switching architecture with identical switching nodes having a topology which allows for multiple paths between any two endpoint switching nodes without intervening switching nodes being involved in call control on those paths. This architecture is made feasible by a new type of link, the flexible rate interface (FRI) link. The FRI link has its own signaling channel distinct from the signaling channel of a standard link and is transparent to intervening switching nodes. Only endpoint switching nodes are aware of the existence of the FRI link with respect to call control. A standard protocol is utilized on the signaling channels of both the standard link and the FRI link. Advantageously, the standard link may be an ISDNlink and the standard protocol may be the ISDN protocol. An FRI signaling channel of the FRI link may be established by using any of the following: a B channel of a standard ISDN link, standard ISDN user information transport facilities, or a logical link of a D channel of a standard ISDN link. In combination with the FRI signaling channel, the FRI link may utilize B channels from a number of standard ISDN links for FRI B channels.
