Title: Method and system for aquaculture production
Inventor: BRAUMAN RICHARD S
IPC: A01K61/00
Filed: 2005-01-10
Abstract: A system (10) and method provide an intensive aquaculture system for produci ng caviar or other goods. The system has a photosynthetic subsystem (30) to consume waste from a production species, a food production subsystem (40) to consume the photosynthetic species and be eaten by the production species. Optionally, the food production species may be pelletized or otherwise refin ed before being consumed by the production species. While each subsystem may ha ve its own water chemistry, gas scrubbers may be used to control gas levels amo ng the subsystems. In one implementation, an enclosure is used with a sensor (314) to measure the gas above the water in the photosynthetic species. Wate r and species may be transferred among the subsystems as desired. Multiple aquaculture systems may be used in combination to provide age-specific syste ms operating in conjunction with one another and distribute risk of disease or failure across multiple systems.

Patent CA-2554806-A1 (CA)
Inventor: MEIER DETLEF G
IPC: B66F11/00
Filed: 2006-07-07
Abstract: During the installation of pipes, valves, fittings, or other materials, people tend to neglect to install guides, slides, pipe supports or a misalignment on piping, or create situations where welding is limited. This creates unnecessary work for the installer and considerable cost to the companies to rectify this problem.   The installer, pipe fitter or welder must rig chain falls or use cranes to lift pipes or other materials to clear the beams to get enough clearance to install the missing pieces. When taking down old or unnecessary pipes, there may not be enough room to use cutters or other means. Since most pipes run parallel close together on a high line, cutting into another pipe is possible causing rupture, causing rupture, causing harm to workers or plant shutdown.   When fitting pipe on a high line, leveling and maneuvering pipe is difficult to do in most instances taking time, machinery and sometimes-unsafe methods to accomplish.
Patent CA-2555832-A1 (CA)
Inventor: LANGE JEFFREY
IPC: G06Q40/00
Filed: 2004-02-11
Abstract: Methods and systems for trading and replicating contingent claims, such as derivatives strategies, in a demand-based auction are described. In one embodiment, a set of demand-based claims, each of which can be a vanilla option or a digital option, approximate or replicate the contingent claim into a vanilla replicating basis or a digital replicating basis, and the order for the contingent claim is then evaluated or processed in the demand-based auction. In another embodiment, a plurality of strikes and a plurality of replicating claims are established for a demand-based auction on an event, one or more replicating claims striking at each of the strikes in the auction. A  contingent claim, such as derivatives strategy, is replicated with a replication set that includes one or more of the replicating claims in the auction. The equilibrium price and/or the payout for the derivatives strategy is determined as a function of the demand-based valuation of each of the replicating claims in the replication set. For a customer order requesting a number of a certain derivatives strategy in the demand-based auction and a limit price per derivatives strategy, the premium of the customer order is determined as a product of the equilibrium price for the derivatives strategy and a filled number of derivatives strategies for the order, each determined as a function of the demand-based valuation of each of the replicating claims in the demand-based auction.

Title: Composition for promoting vascular smooth muscle relaxation
Inventor: DAVIS ADRIAN FRANCIS
IPC: A61K47/10
Filed: 2005-08-08
Abstract: A composition for topical application to a part of the body comprises a vasodilator, for example glyceryl trinitrate, as active ingredient dissolved in a blend of volatile and non-volatile solvents of different solvating capacities for the vasodilator. The vasoldator is present in the composition at a concentration at or slightly below saturation, whereby evaporation of the volatile solvent in use will maintain the vasodilator at saturated or super-saturated concentrations in the residue, whereby the vasodilator will become saturated or supersaturated in the solvent remaining and, as the active ingredient passes through the skin and is absorbed in the bloodstream, and thus becomes depleted in the residual composition, continuing evaporation of volatile solvent will maintain the active ingredient substantially at saturation or supersaturation level in the residual composition throughout the major part of the absorption phase, thereby maximising absorption levels but at a moderate dosage level.
