Title: A solid oxide fuel cell electrolyte
Inventor: WRIGHT GARY JOHN
IPC: H01M8/12
Filed: 2004-06-18
Abstract: A solid oxide fuel cell (10) comprises an anode electrode (12), a cathode electrode (14) and an electrolyte (16) between the anode electrode (12) and the cathode electrode (14). A gaseous fuel is supplied to an anode chamber (18) partially defined by the anode electrode (12) and a gaseous oxidant is supplied to a cathode chamber (20) partially defined by the cathode electrode (14). The electrolyte (16) comprises a first dense non-porous layer (22), a second porous layer (24) on the first dense non-porous layer (22) and a third dense non-porous layer (26) on the second porous layer (24). The anode electrode (12) is arranged on the first dense non-porous layer (22) and the cathode electrode (14) is arranged on the third dense non-porous layer (26).  The second porous layer (24) acts as a buffer between the first dense non-porous layer (22) and the third dense non-porous layer (26) to prevent defects propagating between the layers (22, 26) and to prevent fuel and oxidant leaking through the electrolyte (16).

Patent CA-2532632-A1 (CA)
Inventor: EHRLICH RODNEY P
IPC: B60T7/20
Filed: 2006-01-11
Abstract: An interlock for a slider incorporates a cover that moves between a covered position and an uncovered position. In the covered position, the cover prevents access and movement of a handle for actuating locking pins on the slider. The cover may be pivoted to an uncovered position at which the handle can be actuated. Generally, the handle is pulled away from a trailer frame for the slider to move the locking pins out of holes in the trailer frame. When the cover has moved away from the covered position, the cover actuates a valve member that sets at least one park brake. To release the park brakes, the cover must be moved back to the covered position. The cover cannot be moved back to the covered position until the handle is in a position indicative of the locking pins being fully received in the holes in the trailer frame. In this manner, the cover ensures that the locking pins are fully engaged in the trailer frame, and further provides a visual feedback to an operator of why the park brakes may not be released in the event the locking pins are not fully engaged.

Title: Method for producing ester condensed product
Inventor: ISHIHARA KAZUAKI
IPC: C07D307/24
Filed: 2004-10-01
Abstract: A method for producing an ester condensed product, wherein an esterification reaction is effected by using a catalyst comprising a zirconium (IV) compound and/or a hafnium (IV) compound and an iron compound and/or a gallium compound;  and a catalyst for use in the method. It is preferred that the zirconium (IV) compound is a compound represented by Zr(OH)a(OR1)b[wherein R1 represents an acyl group or alkyl group, and each of a and b is 0 or an integer of 1 to 4 and the relationship of a + b = 4 is satisfied] or a zirconium (IV) halide.  The method allows the production of an ester condensed product having a specific structure by the reaction of equimolar amounts of a carboxylic acid and an alcohol, with the inhibition of the formation of by-products, in good yield, on a large scale, and the catalyst exhibits good catalytic efficiency and is used in a small amount, is reusable and can be repeatedly used. The method can thus provide an industrial process which is desirable from the view point of green chemistry.

Title: Distributing relevant routing information base updates to subscribing clients in a device
Inventor: VICISANO LORENZO
IPC: H04H60/04
Filed: 2004-09-30
Abstract: Route changes are processed and filtered to notify a client of those routing updates of interest to a client. In one configuration, a set of network addresses are received from a client indicating route updates of interest to the client and a set of types of routing changes that are of interest. One or more data structures are accordingly populated with this information. In response to receiving a route update, one or more lookup operations are performed on the data structure to identify whether this particular route is of interest to a particular client and/or whether any route dependent on the particular route are of interest to a client. The client is notified of the changes of interest. In one embodiment, the type of change to a route is also matched against a set of types of routing changes that are of interest, and a client is only notified if the change to a route of interest also matches a type of routing change of interest.

Title: Interlayer for laminated glass and laminated glass
Inventor: SANNOMIYA ISEI
IPC: B32B7/12
Filed: 2000-07-03
Abstract: The present invention provides an interlayer for a laminated glass which does not give rise to the moire phenomenon even when the arrangement and pitch of its embossments are orderly, hence providing for good workability in cutting and laminating operations and good deaeration in preliminary contact bonding, thus insuring the production of a laminated glass of high quality with a minimum of rejects for reasons of air bubbles, and a laminated glass containing said interlayer.

Title: Partition mount with integrated plunger assembly
Inventor: WHITTEMORE JEFFREY P
IPC: A47G5/00
Filed: 2005-05-10
Abstract: A partition mount system includes an integrated plunger assembly. The integrated plunger assembly is constructed and arranged to be integrated into an interior of an end of an extension pole, for example a standard telescoping extension pole. Mounting of the plunger in an interior portion of the pole in this manner provides for a sleek design that is relatively lightweight.  Assuming that the pole in which the anchor is mounted is part of a telescoping pole system, the anchor and, plunger do not interfere with full travel of the interior pole with respect to other poles in the telescoping system. In this manner, operation of the telescoping pole system is not inhibited by the integrated plunger assembly.
