Title: Gas sensors
Inventor: DONCASTER ALAN MASON
IPC: G01N33/00
Filed: 1999-03-03
Abstract: In a catalytic sensor, a bead 1 is located within a can 2 having an aperture 3 in its front surface. The bead 1 is surrounded by thermally insulating material 9, such as glass fibre and a filter material 10 is arranged between the bead 1 and the aperture 3 in the can 2. This acts to remove H2S or other inhibiting gases before they reach the bead 1 and impair its performance. The thermally insulating material allows the filter material to be included whilst still permitting the bead 1 to be operated at a high temperature.

Title: Direction finder and device for processing measurement results for the same
Inventor: KUWAHARA YOSHIHIKO
IPC: G01S3/02
Filed: 1999-03-23
Abstract: A direction finder is provided that can measure the incoming angles of plural incoming signals without spatially moving antenna elements and can be used in outdoor mobile communication environments. The direction finder also can shorten the measurement time. An array antenna (2) consists of plural antenna elements (1) arranged regular intervals. The received signal components due to the mutual coupling between the antenna elements are removed by multiplying time series signal groups by the inverse matrix of a coupling coefficient matrix of the array antenna. The time series signal groups are obtained by modulating signals received with the array antenna. The covariance matrix of the received signal group can be subjected to a movement averaging process (7) in terms of the Vandermonde format. The coupling coefficient matrix of the array antenna is obtained by normalizing the measurement result of an array element pattern containing a mutual coupling with a measurement result of an element pattern of a sole antenna element not containing a mutual coupling and then by expanding the normalized result in a Fourier series.

Title: Ring with reversible setting for displaying alternate faces
Inventor: TANORY JOE RICHARD JR
IPC: A44C17/02
Filed: 1999-03-25
Abstract: Ring includes a front ring or band and a rear ring or band connected together by a body. The front and rear bands are rotatable relative to the body so that either a top face of the body or a bottom face of the body may be displayed by the user, depending on the user's preference. Preferably, a gemstone is provided on the top face of the body, while the bottom face of the body is a metallic face, so that the user has a choice between displaying a gemstone or displaying a metallic face. The metallic face may be made of one or more metals; for example, the top face may be made of one or more of silver, gold, platinum, and the like. The bottom face may be made to hold one or more stones in a setting, such stones being one or more of diamonds, rubies, sapphires, emeralds, and the like. One or both of the front and rear bands may have one or two left and right extensions extending upwardly therefrom. Preferably, the extensions have one or more pintles extending outwardly therefrom for engaging the connector body so that the band may rotate relative to the body to ease rotation for "flipping" of the ring (i.e., the two bands) from its position in which the top face is displayed to the position in which its bottom face is displayed.

Title: Leached nanocrystalline materials, method for making them and uses in the energetic sector
Inventor: SCHULZ ROBERT
IPC: B22F1/054
Filed: 1998-01-21
Abstract: Leached nanocrystalline materials having a high specific surface are particularly useful for storing hydrogen or as catalysts or electrocatalysts in the manufacture electrodes, especially for fuel cells. Such materials can be manufactured by preparing a nanocrystalline material consisting of a metastable composite or alloy of at least two different chemical elements. To be nanocrystalline, this material must have a crystalline structure with the grain size lower than 100 nm. Then, the so prepared nanocrystalline material can be subjected to a leaching treatment in order to eliminate partially or totally one of the elements of the composite or alloy. This leaching results in nanocrystalline materials having a porous structure and, thereby, the requested high specific surface.

Title: Pressurized, integrated electrochemical converter energy system
Inventor: HSU MICHAEL S
IPC: H01M8/24
Filed: 1997-12-23
Abstract: An electrochemical converter is disposed within a pressure vessel that collects hot exhaust gases generated by the converter for delivery to a cogeneration bottoming device, such as a gas turbine. The bottoming device extracts energy from the waste heat generated by the converter, such as a fuel cell for the generation of electricity, yielding an improved efficiency energy system. Bottoming devices can include, for example, a gas turbine system or a heating, ventilation or cooling (HVAC) system. The pressure vessel can include a heat exchanger, such as a cooling jacket, for cooling the pressure vessel and/or preheating an input reactant to the electrochemical converter prior to introduction of the reactant to the converter. In one embodiment, a compressor of a gas turbine system assembly draws an input reactant through the pressure vessel heat exchanger and delivers the reactant under pressure to a fuel cell enclosed therein. Pressurized and heated fuel cell exhaust gases are collected by the pressure vessel and delivered to the turbine system expander. The fuel cell and the pressure vessel function as the combustor of the gas turbine assembly. The expander can perform mechanical work, or can be coupled to a generator to provide electrical energy in addition to that provided by the fuel cell. Also disclosed is a feedthrough for transferring a fluid, such as exhaust gases or an input reactant, from outside the pressure vessel to within the pressure vessel.
