Title: A process for producing a membrane electrode assembly and the membrane electrode assembly produced thereby
Inventor: KOHLER JOACHIM
IPC: H01M8/1004
Filed: 2002-05-17
Abstract: The invention comprises a process for making a membrane electrode assembly comprising a polymer electrolyte membrane having two opposite faces, on each face of which is applied a catalyst layer and a gas distribution layer. The two gas distribution layers in the membrane electrode assembly are formed by hydrophobized carbon substrates which, using appropriate inks containing at least one catalyst, dissolved ionomer and solvent, are each coated with a catalyst layer and are then laid on opposite faces of the polymer electrolyte membrane with the catalyst layers still in the moist state. Afterwards, a firm bond between electrolyte membrane, catalyst layers and carbon substrates is produced by treating the membrane electrode assembly at elevated temperature under pressure.

Title: Use of focused ultrasound for vascular sealing
Inventor: PEROZEK DAVID
IPC: A61B17/00
Filed: 2000-10-25
Abstract: An ultrasonic applicator unit (2) is used diagnostically to locate a puncture wound (316) in an artery and then therapeutically to seal the puncture wound with high intensity focused ultrasound (HIFU). A control unit (6) coupled to the applicator unit includes a processor (74) that automates the procedure, controlling various parameters of the diagnostic and therapeutic modes, including the intensity and duration of the ultrasonic energy emitted by the applicator unit. A protective, sterile acoustic shell (4), which is intended to be used with a single patient and then discarded, is slipped over the applicator unit to protect against direct contact between the applicator unit and the patient and to maintain a sterile field at the site of the puncture.  The apparatus and method are particularly applicable to sealing a puncture made when inserting a catheter into an artery or other vessel.

Abstract: La présente invention concerne une balle de jeu et un procédé de fabrication. Cette balle de jeu possède une enveloppe non ionomérique qui a été polymérisée par l'incorporation d'un peroxyde dialkyle dans le mélange polymère avant le moulage. Cette enveloppe de balle de jeu est supérieure, au moins quant à sa résistance aux coupures ou aux éraflures, à une enveloppe traditionnelle qui ne possède pas de réticulations covalentes mais qui par ailleurs est sensiblement de composition identique. L'enveloppe de balle de jeu de l'invention est particulièrement utile pour améliorer la durabilité des balles de golf frappées par des clubs fortement rainurés. On peut se passer de peroxyde et polymériser l'enveloppe par irradiation après sa fabrication.

Title: Optical recording medium and optical recording method
Inventor: YAMAMOTO MASANOBU
IPC: G11B7/0045
Filed: 2000-10-18
Abstract: An optical alignment film and a liquid crystal thin film are adjacently formed. These films are irradiated with light. The optical alignment film is aligned, and the viscosity of the liquid crystal thin film is lowered because of the increase of the temperature due to light irradiation. The liquid crystal molecules in the liquid crystal thin film are aligned similarly to the alignment of the optical alignment film by use of the intermolecular force at the interface between the optical alignment film and the liquid crystal thin film. The alignment of the liquid crystal molecules allows the recorded information to be held. While using this optical alignment film, a sufficiently large amount of signals are realized, and the thermal stability and the stability against light irradiation are ensured.

Patent CA-2409363-A1 (CA)
Title: Sandcasting pattern coating compositions
Inventor: LAFAY VICTOR STEVEN
IPC: B05D1/00
Filed: 2002-02-07
Abstract: Sand casting is an ald art. In this molding process sand is compacted around a pattern and the pattern is removed, leaving a mold cavity the shape of the pattern.  Molten metal can then be poured into the cavity to form the object. To increase the life of the mold, and to make removal of the pattern easier, the pattern must be coated with a protective material. Despite many available pattern coating compounds, mineral seal oil, and a mixture of mineral seal and clay, have been the commercial choices. Hereby the advantages of mineral seal oil-clay pattern coating compositions are retained without its detriments by utilizing a vegetable oil bare in a pattern coating composition to replace some or all of the mineral seal oil to provide biodegradable coating compositions with reduced VOC content.
