Title: Unambiguous position determination method using two low-earth orbit satellites and system using this method
Inventor: VEMBU SRIDHAR
IPC: H04W84/06
Filed: 1997-09-26
Abstract: A system and method for unambiguously determining the position of a user terminal (for example, a mobile wireless telephone) in a low-Earth orbit satellite communications system (100). The system includes a user terminal (106), at least two satellites (104A, 1104B) with known positions and known velocities, and a gateway (102) (that is, a terrestrial base station) for communicating with the user terminal (106) through the satellites (104A, 104B). The method includes the steps of determining a range parameter (1002, 1102, 1202), a range difference parameter (1004, 1104, 1204), and either or both of a range-rate parameter (1106, 1206) and a range-rate difference parameter (1008 1208). A range parameter represents a distance between one of the satellites (104B, 104B) and the user terminal (106). A range difference parameter represents the difference between (1) the distance between a first one of the satellites (104B, 104B) and the user terminal (106) and (2) the distance between a second one of the satellites (104A, 104B) and the user terminal (106). A range-rate parameter represents a relative radial velocity between one of the satellites (104A, 104B) and the user terminal (106). A range-rate difference parameter represents the difference between (a) a relative radial velocity between a first one of the satellites (104A, 104B) and the user terminal (106) and (b) a relative radial velocity between a second one of the satellites (104A, 104B) and the user terminal (106). The position of the user terminal (106) on the Earth's surface is then determined based on the known positions and known velocities of the satellites (104A, 104B), the range parameter, the range difference parameter, and either or both of the range-rate parameter and the range-rate difference parameter.

Patent CA-2272596-A1 (CA)
Title: Waste water treatment method and apparatus
Inventor: LAMBERT LAWRENCE A
IPC: C02F1/24
Filed: 1999-05-21
Abstract: A method and apparatus for removing impurities from water using electro-flocculation techniques by which water flows under pressure between a series of physically parallel electrically charged plates arranged within a confined chamber so as to provide a tortuous path for the flow of water past the plates. Ozone is entrained in the water as it enters the confined chamber. The pressure is reduced after the water leaves the confined chamber.  The water flow passes through sharp edged openings in the plates so that the overall direction of water flow is generally perpendicular to the plates. The plates are energized by periodic pulses of current of a constant polarity for a selected time interval so that alternate plates differ in potential so as to produce a relatively strong electric field between the plates. The current passing between the plates is controlled by modulating the width of the pulses.

Abstract: In an apparatus for shearing multi-walled workpieces, such as metal framing studs, a base support (16) defines a blade gap (18) therebetween, and a guillotine-like blade (30) is slidably received within the gap for shearing the workpieces. A pair of first supports (20) are each slidably mounted on a respective base support (16, 18). A pair of second supports (22) are also each slidably mounted on the base support, and are spaced apart from and face the first supports to thereby define an adjustable-width channel (28) therebetween. Each of the supports defines a blade-like edge for engaging an elongated, multi-walled workpiece and the first and second support surfaces are each moved into contact with a respective wall of the workpiece. The supports can be oriented relative to one another such that the axis of the channel, and a longitudinal axis of the workpiece received within the channel can be oriented at a desired angle relative to the blade. The guillotine-like blade is then driven downwardly into engagement with the workpiece to shear the workpiece along a line of contact.

Title: Recovery of fermentation salts from dilute aqueous solutions
Inventor: DAVISON RICHARD R
IPC: C07C59/08
Filed: 1998-06-12
Abstract: Dilute solutions of fermentation sales may be concentrated by extracting water using low-miscibility, low-molecular-weight secondary and tertiary amines, e.g. triethylamine (TEA), diisopropyl amine (DIA), N,N-diethylmethylamine (DEMA), and mixtures thereof. At 30 °C-55 °C, which coresponds to typical fermentation temperatures, these low-molecular-weight amines or their mixtures, can extract large amounts of water from dilute aqueous solutions containing fermentation salts.  Thus, dilute fermentation salt solutions can be concentrated by selectively removing water. At these low temperatures, the amine phase contains 20-35 % water and a much reduced quantity of fermentation salt. When the temperature is raised, water phases out of the amine, allowing the amine to be recycled and reused to extract additional water. Using this approach, about 82,5 % of water can be removed from a 3% dilute solution using conventional multistage, countercurrent extraction, thus providing a 15 % concentrated fermentation salt solution.
