Title: Catalytic hydroreforming process
Inventor: CLAUSE OLIVIER
IPC: B01J35/10
Filed: 1998-10-30
Abstract: Hydroreforming and the production of aromatic compounds are carried out in presence of a catalyst comprising a support, a metal of group VIII and an element M chosen from germanium, tin, lead, rhenium, gallium, indium, gold, silver and thallium. The incorporation of M in the catalyst is carried out by dissolving an organometallic compound comprising an M-carbon bond in an aqueous solvent. The catalyst is prepared by: (1) impregnating a support with an aqueous or organic solution of at least a metal of group VIII, filtering, drying, calcining in air and reducing under hydrogen at 20-600 degrees C, preferably 90-500 degrees C; and (2) impregnating the resulting product by an aqueous solution of the additional element M, filtering, drying, reducing and calcining In the preparation of the catalyst, the support is impregnated with an aqueous solution of a compound of the element M, the volume of the aqueous solution being equal or greater than the retention volume of the support. The concentration of M in the aqueous solution of pH 10-14, preferably 10-12, is 0.01-25 mmol/l or 0.5-15 mmol. It is introduced during the elaboration of the catalyst. The feed to be treated contacts the catalyst at 400-700 degrees C and atmospheric pressure-4 MPa with a treated charge flow per unit mass of catalyst between 0.1-10 kg/kgh.

Title: A wing sail and method of use
Inventor: MILIDRAGOVIC MLADEN
IPC: B63H9/06
Filed: 1998-06-22
Abstract: A sail (20) for a sailing vessel (500) includes a leading spar (22), a coplanar trailing spar (24), and a movable spar (28) disposed between the two. A sheath (30) of sail cloth traversely surrounds the three spars forming a flexible double-sided wing-like structure. When the wind (600) blows against sail (20), movable spar (28) is urged toward the leeward side of sail (20), and transforms that side into the curved or long side of an airfoil, thereby creating a push force (54) which propels the sailing vessel (500).
Patent CA-2258601-A1 (CA)
Title: Methods and compositions for the treatment and repair of defects or lesions in cartilage or bone using functional barrier
Inventor: HUNZIKER ERNST B
IPC: A61K38/18
Filed: 1997-06-24
Abstract: Methods and compositions are provided for the treatment and repair of defects in the cartilage or bone of humans and other animals as in full-thickness defects in joints. To induce cartilage formation, a defect in cartilage is filled with a matrix having pores sufficiently large to allow cartilage repair cells to populate the matrix. The matrix contains an anti-angiogenic agent that serves as a functional barrier to prevent vascularization and bone growth into the cartilage area. The matrix filling the defect in cartilage may also contain a proliferation agent and a chemotactic agent, and a transforming factor in an appropriate delivery system. A functional barrier between the bone and cartilage areas of a full-thickness defect may also be created by heat-treating the areas of bleeding to form a transient tissue barrier which prevents blood vessels and associated cells from penetrating from the bone area into the cartilage area. If desired, the bone portion of the full-thickness defect may be filled with a matrix having pores large enough to allow cells to populate the matrix and to form blood vessels. The matrix filling the bone defect may contain an angiogenic factor and an osteogenic factor in an appropriate delivery system. Methods and compositions are also provided for assisted bone and connective tissue regeneration for dental and other applications.
Patent CA-2259767-A1 (CA)
Inventor: BURLEY JOHN S
IPC: A63C19/06
Filed: 1999-01-20
Abstract: A dasher board system for providing a surrounding barrier for the playing surface of a hockey rink. The dasher board system includes lower dasher board sections and extended continuous transparent upper shielding elements. The lower dasher board sections are formed by pultrusion. This gives the dasher board sections a high concentration of fiberglass and a high strength-to-weight ratio. This enables the sections to be made in longer lengths and reduces assembly time. The dasher board sections include horizontal ribs formed therein during the pultrusion process. A mounting system includes supports that are mounted to the horizontal ribs to stabilize the dasher board sections. Curved dasher board sections are formed by cutting the horizontal ribs and flexing the dasher board sections in the regions of the cuts. The transparent upper shielding is formed from by unrolling an elongated length of relatively thin polycarbonate material. The shielding is coupled to wires that extend between the supports, or to the supports themselves. The wires are pulled to tension the shielding and form the upper barrier. The dasher board system can be mounted to numerous different supporting structures, including but not limited to, fence posts, raised concrete curbs, flush concrete rings, and through asphalt surfaces. Alternatively, the dasher board system can be stabilized by supports that are not fixedly mounted to a support surface to permit the dasher board system to be easily assembled and disassembled without affecting the support surface. In one arrangement, the supports can be folded into the dasher board sections to facilitate storage of the system.

Patent CA-2263817-A1 (CA)
Inventor: GRONEMEYER HINRICH
IPC: A61P17/02
Filed: 1997-08-28
Abstract: Cette invention se rapporte à des compositions et à des procédés grâce auxquels on peut traiter un animal, de préférence un être humain, souffrant d'un trouble physique ou ayant une prédisposition pour un tel trouble, en lui administrant une quantité efficace d'une composition contenant au moins un antagoniste de RAR, de préférence un antagoniste de RAR.alpha., et au moins un agoniste de RXR. La combinaison d'un agoniste de RXR, qui n'a pas d'effet thérapeutique tout seul, avec un antagoniste de RAR permet l'utilisation de doses plus faibles de l'antagoniste de RAR par rapport à ce que l'on a pensé jusqu'ici comme étant efficace. Cette approche permet d'éviter un grand nombre des effets secondaires physiologiques indésirables rencontrés lors du traitement avec des antagonistes de RAR.
