Patent CA-2641802-A1 (CA)
Inventor: LAZEBNIK BORIS S
IPC: F28D15/04
Filed: 2006-02-22
Abstract: An apparatus for vaporizing a liquid and heating the vaporized liquid to an elevated temperature. The apparatus has a heat transfer wall having an outer surface for receiving heat and transferring the heat to an inner surface. A  wick material is disposed so that a portion of the wick material is in contact with the inner surface and another portion is remote from the heat transfer wall. A wick support in contact with the wick material opposite the inner surface of the heat transfer wall provides structural support to the wick material and further provides a path for vaporized liquid to flow from the wick material. Vaporizable liquid is delivered to the portion of the wick material that is remote from the heat transfer wall and is allowed to migrate to the portion that is in contact with the inner surface. Heat from the inner surface converts the liquid to a vaporized liquid. Optionally, a gaseous fuel may be introduced into the wick support for pre-heating and mixing with the vaporized liquid. Vaporized liquid flows out of the wick material through the wick support and into a downstream superheater that preferably houses a heat exchange device. The heat exchange device is in thermal communication with the inner surface of the heat transfer wall for receiving and transferring heat to the vaporized liquid. The apparatus can include multiple vaporization units connected to common and/or different heat sources. Methods for making an apparatus for vaporizing a liquid and methods for vaporizing a liquid are also disclosed.

Title: Method, system, and apparatus for controlling an electric motor
Inventor: BOYADJIEFF GEORGE I
IPC: H02K23/00
Filed: 2007-06-01
Abstract: The present invention provides systems and methods for power factor control of a motor. A phase detector uses a line voltage of a power supply and a motor terminal voltage of a motor. The output of the phase detector is synchronized to a zero crossing of the motor current of the motor and a zero crossing of the line voltage. A digital microprocessor connected between the output of the phase detector and a rectifier driver senses a first time at which a phase of the motor voltage is crossing zero volts and a second time at which a phase of the motor current is crossing zero current. The digital microprocessor calculates the difference in time between the first and second times and uses the difference in time to calculate a phase lag of the motor. The digital microprocessor uses the phase lag to calculate a firing time of a rectifier to command power efficiently to the motor.

Inventor: STEVENS GEOFF
IPC: C10G1/04
Filed: 2009-10-20
Abstract: A process and system for treating bitumen froth with paraffinic solvent is provided which uses three stages of separation. Froth and a first solvent are directed to a first stage at a solvent/bitumen ratio for precipitating few or substantially no asphaltenes. A first stage underflow is directed to a second stage and a first stage overflow is directed to a third stage. A second stage underflow is directed to waste tailings and the second stage overflow joins the first stage overflow. A third stage underflow is recovered as an asphaltene by-product and a third stage overflow is recovered as a diluted bitumen product. At least a second solvent is added to one or both of the second or third stages for controlling a fraction of asphaltenes in the third stage underflow. Asphaltene loss to waste tailings is minimized and asphaltenes are now recovered as asphaltene by-product.

Abstract: A mobile communication device (e.g. a handheld telephone device) has a first wireless transceiver for communications via a wireless communication network and a second wireless transceiver for communications with a wireless peripheral device (e.g. a wireless audio headset or earpiece). The mobile device receives, from the wireless peripheral, an identification of a type or model of the wireless peripheral.  The mobile device causes user interface (UI) function mapping information of the wireless peripheral to be selectively retrieved based on the received identification of the type or model. The UI function mapping information is indicative of a plurality of device functions assigned to a plurality of user input controls of the wireless peripheral. UI  instruction information which is based on the retrieved UI function mapping information is then displayed at the mobile device. For example, when an incoming call is received, UI instruction information which identifies a first user input control for causing the incoming call to be answered and a second user input control for causing the incoming call to be ignored is displayed. The UI function mapping information may be selectively retrieved by transmitting, via the first wireless transceiver, a request which indicates the type or model of the wireless peripheral, for receipt by a server having different sets of UI function mapping information stored in association with a plurality of different types or models of wireless peripherals.
