Patent CA-2455075-C (CA)
Title: Propulsion linearizing mechanism
Inventor: ASHWORTH ERIC
IPC: F01D1/20
Filed: 2002-08-06
Granted: 2010-07-20
Abstract: A fluid flow control mechanism is provided for linearizing a fluid flow. The mechanism includes a frame having a cylindrical outer baffle which rotatably supports a plurality of propeller elements thereon. Each propeller element defines a respective sweep area as the propeller element is rotated which overlaps sweep areas of adjacent propeller elements. The outer baffle circumscribes an outer periphery of the collective sweeps areas of the respective propeller elements. The propeller elements rotate in the same direction whereby forces of curvature flow of adjacent propeller elements substantially cancel one another to linearize fluid flow through the mechanism. Additional baffles and infills within the areas of non blade sweeps may be provided for particular applications of the mechanism. In various applications, linear forces of vector flow are formed by integrating curvature forces of tangential flow and economy flow systems are formed by integrating curvature forces potentials on the planes of rotating propellers to provide the emission and induction flow with an insulation whereby fluid in the immediate vicinity of the mobile flow remains in an undisturbed static state.  This allows a fluid propulsion assembly to be fitted with an outer utility mantle in the static zone of the field.

Title: Tubular expansion apparatus and method
Inventor: KARA FATIH M
IPC: E21B43/10
Filed: 2002-09-30
Granted: 2008-07-29
Abstract: Tools for expanding downhole tubulars into each other or in open hole are disclosed. One embodiment uses a movable cone (50) biased by Bellville washers to move longitudinally against such bias and allow collets (40) to move radially in or out to a predetermined maximum diameter. A release system allows collet retraction to avoid hang up on removal. In an alternate embodiment, more suitable for open hole applications, pressurized gas pushes a movable cone longitudinally against the collets. A stationary cone is on the opposite side of the collets from the movable cone. The collet rides out or in between the cones and raises the gas pressure when forced in. A pressure actuated release allows the lower cone to shift downwardly to allow the collets to retract for removal.

Granted: 2007-10-09
Abstract: A floor care appliance is provided with an improved power management system for controlling the total amount of current provided to at feast a first and a second load device of an appliance. The power management system is comprised of a microprocessor, an alternating current voltage source, a voltage regulating circuit, a clamping circuit, at least two load devices, and a MOC and a triac for each of the at least two load devices. The clamping circuit outputs a fixed voltage of 5.7 volts during the positive portion of the ac cycle and a fixed voltage of -0.7 volts during the negative portion of the ac cycle. The fixed voltages are input to a microprocessor which utilizes these inputs to control the average voltage and the amount of time the current is turned on to each of the at least first and second load devices. A current sensing circuit is used to monitor the current to one of the at least two load devices to provide feedback to the microprocessor so that the microprocessor can adjust the average voltage and current to the at least two load devices so that the total current consumed does not exceed a pre-determined level.

Abstract: A rock stabilizer includes an elongated metal tube having and interior and an exterior surface with a distal end and a proximal end. The distal end is tapered and a flange is positioned adjacent the proximal end. The tube further includes a slit that runs substantially the entire length thereof. The tube is constructed so as to be capable of being positioned within a bore formed in the wall of a mine. A plurality of indentations or recesses are formed in the outer surface of the tube along the length thereof adjacent the slit so that grout or resinous material pumped into the interior of the tube can flow out of the slit and into the indentations or recesses. An expander wedge is also located within the interior of the tube adjacent the distal end and is actuatable from the proximal end of the tube after said stabilizer is installed in a bore. The wedge expands the distal end of the tube to firmly anchor the stabilizer in the bore. The expander wedge is formed of two wedges, one of which is welded to the interior of the tube and the other is capable of being moved toward the fixed wedge. The two wedges are temporarily maintained together while they are in the interior of the tube and before they are actuated.

Abstract: A method and apparatus for treating wastewater streams by adding, either separately or as a mixture, a nitrate containing compound and an alkaline material in an amount sufficient to achieve a lower concentration of atmospheric hydrogen sulfide and dissolved sulfides downstream of the addition as compared to the atmospheric hydrogen sulfide and dissolved sulfides present in the wastewater stream prior to the addition. By adding alkaline material in addition to a nitrate containing compounds, the amount of nitrate containing compound added can be reduced by at least 10% as compared to the amount of nitrate that would theoretically need to be added in the absence of alkaline material to achieve a comparable lower concentration of atmospheric hydrogen sulfide and dissolved sulfides in the wastewater stream.

Abstract: Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
