Patent CA-2302135-A1 (CA)
Inventor: ROBEY RAYMOND JOHN
IPC: B01D11/04
Filed: 2000-03-27
Abstract: A process for extracting a component from liquids using dense phase gases or supercritical fluids (dense phase solvent). The process contacts a liquid and the dense phase solvent in a rotating mixer to dissolve a desired fraction into the dense phase solvent to form a loaded solvent. Furthermore, the mixer separates the loaded solvent from the remaining raffinate. Then the rotating mixer discharges the loaded solvent and raffinate. Decreasing pressure on the loaded solvent converts the loaded solvent into a gas and the desired fraction to liberate the desired fraction from the gas.

IPC: H04L27/26
Filed: 1998-09-14
Abstract: A method and a device for test receiving alternative frequencies without interrupting the reception of DAB frames from the current reception frequency in a DAB receiver. A DAB frame comprises a null symbol which is used to do a first very coarse synchronisation of the receiver to the transmitted signals.  According to the invention, test receptions of alternative frequencies occur during the currently received programme's null symbols. By performing test receptions during the current programme's null symbols the current programme is not interrupted at all during the test receptions. A subsequently determined frequency changeover can thereafter, with a high probability, be performed without any noticeable interruption.

Patent CA-2310012-A1 (CA)
Inventor: KOZICZ JOHN RICHARD
IPC: B63B35/44
Filed: 1998-11-13
Abstract: A semi-submersible structure is adapted to carry consumable solid or liquid material such as mud, and removable equipment, for example drilling tubulars. Both consumables and removable equipment are removed from the structure during use, thereby reducing the structure's total mass. The structure is provided with pontoon means (4, 8) containing a first set of compartments (66, 68, 70, 72, 84, 86, 88) for consumable material and ballast control means for introducing ballast into the first set of compartments to compensate for the removal of consumable material. The structure also includes dedicated ballast tanks (40, 42, 56, 106, 108), but the arrangement is such that, if the first set of compartments is empty, and no consumable material or removable equipment is being carried by the structure, the filling of the ballast tanks with ballast will not cause the structure to be submerged to an extent sufficient to achieve a semi-submerged condition (the structure therefore still being over-buoyant), whereas said condition would be achieved if the first set of compartments (66, 68, 70, 72, 84, 86, 88) were also at least partially filled. The structure thus includes "dual purpose" compartments which can accept either consumable materials or ballast, thereby increasing the effective deck load of the structure.

Abstract: A continuous stream of formatted digital data, such as a video segment, audio segment, or information stream, appears to be a fixed length segment under certain circumstances, defining a virtual segment within the continuous stream which moves forward in time in synchrony with the continuous stream. The virtual segment thus defined can be explored in a non-linear fashion at arbitrary playback rates. For instance, concepts such as rewind, pause, frame advance, and fast forward become meaningful even though the continuous stream never ceases.

Abstract: An apparatus and method is disclosed for attaching a data sub-channel to a digital payload for communicating supplemental data within an optical communications network. At an upstream site a digital clock is phase-modulated with an encoded supplemental data stream to generate a phase-modulated sub-channel. The phase-modulated clock is used to time the payload data stream so as to superimpose the phase-modulated sub-channel onto the payload data stream. At a downstream site the sub-channel is recovered and the clock is used to retime the payload data stream. The sub-channel is then demodulated and the supplemental data stream decoded.
