Abstract: A refrigeration system comprising a compressor (100)for compressing a refrigerant, a condenser (107) for condensing refrigerant to a liquid, an evaporator (103) for evaporating liquid refrigerant from the condenser (107) to a gas, an inner control loop for optimizing a supply of liquid refrigerant to the evaporator (103), and an outer control loop for optimizing a level of refrigerant in the evaporator (103), said outer control loop defining a supply rate for said inner control loop based on an optimization including measurement of evaporator (103) performance, and said inner control loop optimizing liquid refrigerant supply based on said defined supply rate.  Independent variables, such as proportion of oil in refrigerant, amount of refrigerant, contaminants, non-condensibles, scale and other deposits on heat transfer surfaces, may be estimated or measured. A model of the system and/or a thermodynamic model approximating the system, for example derived from temperature and pressure gages (155, 156), as well as power computations or measurements, is employed to determine or estimate the effect on efficiency of deviance from an optimal state. Various methods are provided for returning the system to an optimal state, and for calculating a cost-effectiveness of employing such processes.

Patent CA-2515436-A1 (CA)
Inventor: NIELSEN JOHN GODSK
IPC: F03D9/00
Filed: 2003-02-07
Abstract: The present invention relates to a method and an apparatus for controlling a power-grid connected wind turbine generator during grid faults. During grid faults, the stator windings of the wind turbine generator are disconnected from the power grid and impedances for dissipating at least part of the power generated by the wind turbine during grid fault condition are connected to the stator windings. In this way, a certain magnetisation of the generator can be maintained and after removal of the grid fault condition, the generator is synchronised to the power grid and the impedances are disconnected and the stator windings are reconnected to the power grid. In this way, it is possible to keep the wind turbine generator at least partly magnetised during grid faults and thus ready for delivering power to the power grid, as soon as the grid voltage is re-established after the fault.

Patent CA-2521601-A1 (CA)
Title: Improved audio coding systems and methods using spectral component coupling and spectral component regeneration
Inventor: VERNON STEPHEN DECKER
IPC: G10L21/02
Filed: 2004-04-30
Abstract: An audio encoder discards spectral components of an input signal and uses channel coupling to reduce the information capacity requirements of an encoded signal. Channel coupling represents selected spectral components of multiple channels of signals in a composite form. An audio decoder synthesizes spectral components to replace the discarded spectral components and generates spectral components for individual channel signals from the coupled-channel signal. The encoder provides scale factors in the encoded signal that improve the efficiency of the decoder to generate output signals that substantially preserve the spectral energy of the original input signals.

Inventor: FACEY RODERICK M
IPC: C10G1/00
Filed: 2005-12-12
Abstract: A process for the separation of bitumen oil from tar sands and the like.  Slurry is supplied to a mixing chamber of a jet pump at an input end of the process. Non-ionic surfactant, and optionally diluent, are added to the slurry. The slurry is agitated within the jet pump to effect a partial to full phase separation of the oil fraction from the solids fraction of the slurry. The partially to fully separated slurry is discharged into a pipeline and later into a hydrocyclone to effect a second phase separation of the slurry. One or more hydrocyclone separators may be used to separate the bitumen oil and liquid from the solids fraction.
Patent CA-2535935-A1 (CA)
Inventor: GILBERT GUY
IPC: E04F15/20
Filed: 2006-02-09
Abstract: The floor structure has a base layer fastened to floor joists, a resilient layer laid over the base layer, and a top layer mounted over the resilient layer.  The top layer has a stiffness that is greater than a stiffness of the base layer.  The top layer is fastened to the base layer by wood screws that are placed substantially along a median between two adjacent floor joists. Each screw has a threaded portion extending simultaneously in both the top and the base layers. The installation of screws through the top and the base layers causes a backlash in the advance of the screws upon entering the base layer, thereby causing the occurrence of a larger gap between the layers as compared with an installation using nails. The larger gap relaxes a pressure on the foam layer and reduces the transmission of sound energy to the joists.
