Patent CA-2232948-C (CA)
Title: Enhancement of flow rates through porous media
Inventor: HAYES KIRBY WARREN
IPC: E21B43/16
Filed: 1998-03-24
Granted: 2005-06-07
Abstract: For extracting a liquid (such as oil) from a porous medium, the liquid is subjected to pulses that propagate through the liquid flowing through the pores of the medium. The pulses cause momentary surges in the velocity of the liquid, which keeps the pores open. The pulses can be generated in the production well, or in a separate excitation well. If the pulses travel with the liquid, the velocity of travel of the liquid through the pores can be increased. The solid matrix is kept stationary, and the pulses move through the liquid. The pulses in the liquid can be generated directly in the liquid, or indirectly in the liquid via a localised area of the solid matrix.

Abstract: A method and arrangement are disclosed for transmitting television programs via a plurality of channels, and an additional data service, for example, an Electronic Program Guide, via a selected television channel. While processing and displaying the program guide, prior art television receivers cannot continue the reproduction of a currently received TV program because the program is generally transmitted via a different channel. The invention provides a solution to this problem by duplicating a signal component representing, for example, the audio contents of the various television programs in said selected television channel. This allows customers to keep up with the service they were watching before, and to immediately return to the program if something of interest appears to happen. The invention is particularly applicable in Digital Video Broadcast (DVB) systems where each channel can accommodate a plurality of TV programs.

Granted: 2003-05-20
Abstract: A compact power supply apparatus is favorable for a reduction in size of a mobile communication terminal having a transmitter and baseband signal processor, a transmitter and a power amplifier. The power supply apparatus includes a DC/DC converter for converting a DC voltage from a battery. In a reception mode of the mobile communication terminal, the power supply apparatus regulates the DC voltage converted by the DC/DC converter and supplies the regulated DC voltage to the receiver and baseband signal processor. In a transmission mode, the power supply apparatus converts the DC voltage converted by the DC/DC converter to a DC voltage corresponding to a transmission AGC (Automatic Gain Control) voltage determined depending on a transmission power and supplies the converted DC voltage to the receiver and baseband signal processor, the transmitter and the power amplifier. Since the power supply apparatus uses a single DC/DC converter and adaptively varies the output voltage of the DC/DC converter according to the transmission power in the transmission mode, it is favorable for a reduction in size of the mobile communication terminal and for a reduction in power loss of the voltage regulators and the power amplifier, thereby maximizing the power efficiency and extending the battery life.

Title: Electrostatic/mechanical emulsion treating method and apparatus
Inventor: BUCHANAN VINCENT P
IPC: B03C5/02
Filed: 1999-09-23
Granted: 2004-09-21
Abstract: A treater for electrostatically and/or mechanically separating emulsified brine from oil during longitudinal flow through a horizontally elongated metal tank, wherein adjustable distributor elements are provided for enhancement of the de-emulsification process. The adjustable distributor elements may be externally operated to more closely control the diffusion and distribution of the flowing emulsion across the transverse area of the treater.      The emulsion may be first directed through electrical fields where the brine droplets take on an electrical charge, then move through the distributor elements to electrically grounded coalescing elements. De-emulsified oil is removed in a stream separate from the brine stream. The treater also operates mechanically, with reduced efficiency, when electrostatic operation is unavailable, and can also be operated if coalescing elements are not used. The externally-adjustable, louvered baffles may be accompanied by fixed, non-adjustable louvers at intermediate spacing between the externally-adjustable louvers to provide additional coalescing and flow direction that will enhance dehydration of the process stream, and become an integral extension component thereof.

Filed: 2000-07-07
Granted: 2007-12-04
Abstract: A method for separating charged particles according to their mass requires providing a multi-species plasma in a chamber The plasma includes both relatively low-mass charged particles (M1) and relatively high-mass charged particles (M2) which are influenced by crossed electric and magnetic fields (E × B) in the chamber. Specifically, the crossed fields (E × B) rotate the particles M1 and M2 in respective orbits that are characteristic of the mass of the particular particle. Inside the chamber, each charged particle has a respective cyclotron frequency (.OMEGA.), and the plasma is maintained with a density wherein the collisional frequency (v) of particles in the chamber relates to the cyclotron frequency such that their ratio is greater than approximately one (.OMEGA./v >=1). Additionally, a collector is positioned to intercept the particles (M2) in their orbits and to thereby separate the particles (M2) from the particles (M1).
