Title: Procede de fabrication de tubes en ceramique a extremite fermee pour piles a combustible
Inventor: BORGLUM BRIAN P
IPC: H01M8/12
Filed: 1999-04-09
Abstract: Procédé de fabrication de tubes en céramique à extrémité fermée pour piles à combustible, ayant des propriétés améliorées et présentant un rendement de fabrication plus élevé. Ledit procédé consiste à fixer un bouchon non cuit (22) à un tube creux non cuit (20) pour former un joint composé. L'ensemble est ensuite cuit et présente la forme définitive, sans qu'il soit nécessaire de procéder à un usinage ultérieur. Le tube à extrémité fermée qui en résulte est supérieur en cela qu'il fournit une étanchéité empêchant toute fuite et que sa porosité est pratiquement identique à celle de la paroi du tube. Le rendement de fabrication plus élevé associé au procédé selon la présente invention entraîne une baisse significative du coût total de la pile à combustible.

Title: Method and apparatus for compressing a bose-einstein condensate of atoms
Inventor: LAOR HERZEL
IPC: H05H1/22
Filed: 1999-04-29
Abstract: A Bose-Einstein condensate (102) of atoms is compressed and/or rapidly de-condensed in the reaction chamber (104) by a beam (109) in order to achieve nuclear fusion. A pre-formed Bose-Einstein condensate of atoms may be introduced into the reaction chamber (104), or the constituent atoms of the Bose-Einstein condensate may be introduced into the reaction chamber (104) with formation of the Bose-Einstein condensate from the constituent atoms occurring subsequently inside the reaction chamber (104). The constituent atoms of the Bose-Einstein condensate may be bosons, Fermions or both. The beam (109) is directed at and focused on the Bose-Einstein condensate so as to maximise the total compression of the Bose-Einstein condensate. Upon de-condensing, the Bose-Einstein condensate atoms fuse, releasing substantial amounts of energy. This energy is harnessed and used to drive a turbine (120) to run a generator (122).

Title: Validation method for electronic cash cards and digital identity cards utilizing optical data storage
Inventor: DREXLER JEROME
IPC: G06K19/06
Filed: 1999-11-29
Abstract: A method for inhibiting the counterfeiting of electronic cash smart cards (11) that use microchips for monetary stored value or digital identity cards that use microchips to control the transfer of data. Such electronic cash cards have recently been counterfeited by the use of electronic techniques to break the security codes.  Such counterfeiting can be inhibited by bonding an optical memory stripe (17) to the smart card with pre-recorded or post-recorded validation data (19) at one or multiple locations on the cards.    This optical validation data would be read with a photodetector array and could be transmitted to the recipient during funds transfer and/or used locally to control dispensing of cash or data. Thus successful counterfeiting of the modified electronic cash or digital identity card would require meeting exacting electronic and optical requirements.
