Patent CA-2533914-A1 (CA)
Inventor: PEARS DAVID ALAN
IPC: B01J31/18
Filed: 2004-08-13
Abstract: A microencapsulated catalyst-ligand system is prepared by dissolving or dispersing a catalyst and/or a ligand in a first phase (for example an organic phase), dispersing the first phase in a second, continuous phase (for example an aqueous phase) to form an emulsion, reacting one or more microcapsule wall-forming materials at the interface between the dispersed first phase and the continuous second phase to form a microcapsule polymer shell encapsulating the dispersed first phase core and when the first phase contains only a catalyst or a ligand, treating the microcapsules with the remaining ligand or catalyst component of the catalyst-ligand system. The catalyst is preferably a transition metal catalyst and the ligand is preferably an organic ligand. The encapsulated catalyst-ligand system may be used for conventional catalysed reactions. The encapsulated catalyst-ligand system may be recovered from the reaction medium and re-cycled.

Abstract: The present invention provides a subfloor system for placement over a substrate and method of forming a sports floor therewith. The subfloor consists of a base (10), a resilient pad (20), an upper member (22), and brackets (30, 32). The resilient pad is positioned on the base, preferably with an elongated slot (12) formed in the upper surface of the base. The upper member has a projection (24) and two shoulders (26, 28) and is operably connected to the top surface of the resilient pad. The brackets have upper (36, 37) and lower (34, 35) tabs and are secured to the base and to the upper member.

The thermal members (31) are traversed by a conduit containing a heating medium and connected to one or more heating medium circuits. In the presence or in the absence of the magnetic field, the temperature of the thermal members (31) rises or drops to a temperature below the initial temperature. The calories and frigories emitted by the thermal members (31) are recuperated by the heating medium to be evacuated via exchangers. The invention is useful for tempering, cooling, heating, preserving, drying, air conditioning.

Patent CA-2549782-A1 (CA)
Inventor: CRICHLOW HENRY B
IPC: E21B43/243
Filed: 2006-05-08
Abstract: Recovery of viscous hydrocarbon from subterranean formations is assisted by using a plurality of novel U-tube type wells, each with dual wellheads, a moveable wellbore packer, a lateral section with a concentric communication zone and with sequential injection production perforations in which heat is injected into the proximal perforations and hot oil and produced fluids are produced from the distal perforations, the whole process being controlled by modulating the production flow where the wellbore fluids are controlled to act as a hydraulic seal to limit bypass of injected fluids. The injection-production displacement process moves axially along the wellbore in a sequential manner as hydrocarbon volumes are depleted by injected fluid displacement of oil and oil and water production.

Title: A process for tritium removal from water using transfer to an elemental hydrogen stream, membrane diffusion stripping and final thermal diffusion enrichment
Inventor: BUSIGIN ANTHONY
IPC: B01D59/16
Filed: 2006-06-22
Abstract: A diffusion based process for tritium removal from water by tritium transfe r from water to an elemental hydrogen stream, followed by a membrane diffusion cascade for tritium stripping and enrichment, and final tritium enrichment b y one or more thermal diffusion columns. The combination of process steps takes advantage of membrane diffusion's large throughput capability at low tritium concentration with the simplicity of thermal diffusion for small throughput final tritium enrichment. The membrane diffusion stages use supported or unsupported microporous or hydrog en permeable metal membranes (such as Pd/Ag alloy). The diffusion process is compatible with any front-end process to transfer tritium from tritiated wat er to elemental hydrogen. The process may be designed and operated at low pressure , with small gas inventory, and no inherent overpressure hazard.

Title: Recovery method for lost signaling connection with high speed downlink packet access/fractional dedicated physical channel
Inventor: TOSKALA ANTTI
IPC: H04W76/02
Filed: 2005-06-20
Abstract: A method and apparatus are provided for defining terminal behavior in a case where the terminal detects that it cannot receive the HS-DSCH from a serving cell reliably when the DCCH is mapped to HS-DSCH (e.g. does not receive any radio link control (RLC) acknowledged mode feedback for the uplink measurement reports or in general the common pilot channel (CPICH) level drops too low in the serving HS-DSCH cell). The terminal is autonomously moved to a cell forward access channel (CELL_FACH) state and uplink signaling is initiated on a random access channel (RACH) to inform a network node and ask for HS-DSCH re-establishment in a suitable cell, or setting up a regular R'99/R'5 DPCH in order to restore the RRC signaling connection in the CELL_DCH state.
