Patent CA-2178074-A1 (CA)
Title: Method and system for mooring floating storage vessels
Inventor: PORANSKI PETER F SR
IPC: B63B21/50
Filed: 1994-11-29
Abstract: A method and sytem of mooring a storage vessel in the sea is provided. A turret (20) is  mounted in a well (18) forward of the vertical centerline of the vessel. A plurality of anchor legs (26) are disposed between the sea bed and in the turret (20). Each anchor leg (26) is fixedly secured to the turret (20). A mooring buoy (28) is fixedly secured at a submerged position in each anchor leg (26) substantially horizontally outwardly from the turret (20). The position and buoyancy of the buoy (28) is selected so that normal anchor leg catenary forces which are largely vertical at the connection to a turret have enhanced horizontal components due to the buoyancy of the buoy (28) holding up the anchor leg at a submerged position in the sea. Such enhanced horizontal components enable sufficient torque to be developed between the vessel (10) and the turret (20) so that the vessel may weathervane due to environmental forces such as wind and current. Accordingly, the vessel (10) may be maintained on station and achieve a heading toward environmental forces without the need for auxiliary thrusters or separate turret drive. Further, the anchor legs (26) are well clear of the risers (22) from the sea bed irrespective of turbulent sea conditions Accordingly, there is no need to disconnect the storage vessel from the anchor lines in rough seas.

Title: Selective delivery conveyor system
Inventor: CAILEY RON
IPC: B61B13/04
Filed: 1995-01-03
Abstract: A material handling and transport system for transporting goods between a number of discharge/induction stations and selectively receiving and discharging goods at the stations.  A moving transport unit (24), for example a train-type string or cars (28, etc.) or trolleys with tilting trays (70, etc.) for receiving, transporting and discharging goods between induction (38) and discharge stations (52, etc.) positioned along a track (22), incorporates a number of self-contained, locally controlled sensing (58), signal (62, etc.) and actuation (30) devices which allow the trolleys to selectively interact with passive stations around the track.  The centralization of systems control (54) on the trolleys themselves, as opposed to on the track-side stations, results in greater system flexibility, reduced cost, and allows the train to operate in essentially autonomous mode without the need for external control and monitoring.

In another embodiment the movable elements are rigid and form (when extended) bases for trays and lie immediately beneath side supports hinged to the back wall and rotatable from positions parallel to that wall to positions extending normally of that wall to act as end (and possibly) divider walls for the trays. A front wall (110) for each tray may be provided by a web carried between free edges of the side supports or by a rigid front wall part hinged to the free edge of the movable element and rotatable from a positions parallel to that element to position extending normally thereof. The container may be of a foldable fabric, the movable parts being pockets carrying rigid planar pieces stitched to the back wall and resting when extended against parts of the frame. When not in use the fabric part may be folded and the frame collapsed for storage or transportation. The container may also be implemented in plates of metal or other rigid material with hinges between the movable parts.

Title: Semiconductor device having planar type high withstand voltage vertical devices, and production method thereof
Inventor: SAKAMOTO KAZUHISA
IPC: H01L21/20
Filed: 1996-04-11
Abstract: An IGBT having a high withstand voltage, small power consumption and small device formation area. An n-- type semiconductor layer (38) is provided at a portion which is likely to cause surface breakdown, and an n- type semiconductor layer (36) is disposed below the former. Therefore, the theoretical withstand voltage in the n-- type semiconductor layer (38) is higher than the theoretical withstand voltage in the n- type semiconductor layer (36), and the surface breakdown voltage can be correspondingly increased. Since the n- type semiconductor layer (36) having a lower resistance is disposed below the n-- type semiconductor layer (38), the region which affects power consumption of the IGBT has a lower resistance, and power consumption becomes smaller.

Title: Recombinant virus vectors
Inventor: SPECK PETER GERALD
IPC: A61K35/76
Filed: 1995-07-28
Abstract: A mutant herpesvirus that can be used as a recombinant virus vector comprises (a) a mutation such that the mutant virus has a reduced ability in comparison with a parent type to cause lysis of an infected cell, and (b) an inactivating mutation in a gene essential for the production of infectious virus. An example is a HSV1 mutant lacking the essential glycoprotein gH gene and having a mutation impairing the function of gene product VP16. A heterologous gene can be carried at the site of the inactivated essential gene, e.g. a gene suitable for administering gene therapy. The vector has an increased margin of safety over known herpesvirus vectors in respect of incidence of cytopathic effects and/or risk of reversion.

Title: Genetic therapy of diseases caused by the immune system, said therapy using a cell-specific active substance regulated by the cell cycle
Inventor: MUELLER ROLF
IPC: A61K48/00
Filed: 1995-08-25
Abstract: The invention concerns a DNA sequence for the genetic therapy of diseases caused by the immune system. The essential components of the DNA sequence consist of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated cell or virus-specifically and the promoter module regulates this activation specifically according to the cell cycle. The choice of activator sequence and active substance depends on the indications. The DNA sequence is introduced into a viral or non-viral vector, supplemented by a ligand having affinity for the target cell.  Depending on the choice of activator sequence and active substance, the following conditions can be treated by administration of the DNA sequence: the defective formation of blood cells; autoimmune diseases and allergies as well as rejection reactions against transplanted organs; chronic arthritis; viral and parasitic infections as well as the prevention of viral, bacterial and parasitic infections; leukaemias.
