Patent CA-2485941-A1 (CA)
Inventor: MCCAUSLAND LINDA JANE
IPC: C07K5/072
Filed: 2003-05-13
Abstract: A crystalline material sufficiently pure for use in pharmaceuticals may be made by forming a saturated solution of the material, changing the temperature of the solution so it becomes supersaturated, and subjecting the solution to irradiation by high intensity ultrasound, the frequency of the ultrasound being scanned over a range of frequencies. For example the ultrasound may be varied between 19.5 and 20.5 kHz, and this variation may be sinusoidal.  Preferably the ultrasound is provided only briefly, say for less than 5 s, before allowing the solution to cool gradually without further irradiation.  The ultrasound may be applied using a vessel with an array of ultrasonic transducers attached to a wall, so each transducer radiates no more than 3 W/cm2 yet the power dissipation within the vessel is between 25 and 150 W/litre. This method can reduce the metastable zone width to less than 10 K.  It is applicable in particular to aspartame.

Title: Method for forming spread nonwoven webs
Inventor: BERRIGAN MICHAEL R
IPC: D04H3/03
Filed: 2003-05-13
Abstract: A new fiber-forming method, and related apparatus, and webs prepared by the new method and apparatus are taught. In the new method a) a stream of filaments is extruded from a die of known width and thickness; b) the stream of extruded filaments is directed through a processing chamber that is defined by two narrowly separated walls that are parallel to one another, parallel to said width of the die, and parallel to the longitudinal axis of the stream of extruded filaments; c) the stream of filaments passed through the processing chamber is intercepted on a collector where the filaments are collected as a nonwoven fibrous web; and d) a spacing between the walls of the processing chamber is selected that causes the stream of extruded filaments to spread before it reaches the collector and be collected as a web significantly wider in width than the die. Generally the increase in width is sufficient to be economically significant, e.g., to reduce costs of web manufacture. Such economic benefit can occur in widths that are 50, 100 or 200 or more millimeters greater in width than the width of the die. Preferably, the collected web has a width at least 50 percent greater than said width of the die. The processing chamber is preferably open to the ambient environment at its longitudinal sides to allow pressure within the processing chamber to push the stream of filaments outwardly toward the longitudinal sides of the chamber.

Title: A slow-release agrochemicals dispenser and method of use
Inventor: BURNET MICHAEL WILLIAM
IPC: A01N25/26
Filed: 2003-07-03
Abstract: Acetolactate synthase inhibitors, such as imazapyr and pyrithiobac and mixtures thereof, prepared as slow-release formulations are useful for the preparation of seed dressing, seed priming, seed or particle-substrate coating herbicidal compositions for control of parasitic weeds such as Orobanche spp., Striga spp. and Alectra spp. The use of agrochemicals can be rendered more efficient when coated or bound as a slow release formulation. Particles used as the substrateto be coated may be plant seeds or particles made of a strong or weak ionic resin or a biodegradable carbohydrate natural polymer, a modified polymer, or artificially lignified cellulose. The herbicidal formulation may be covalently linked or adsorbed to the surface of the particle. The same slow release formulations are invaluable for preventing rapid herbicide leaching in agricultural as well as non-agricultural weed control situations.

Title: Method for upward growth of a hydraulic fracture along a well bore sandpacked annulus
Inventor: HILL GILMAN A
IPC: E21B47/00
Filed: 2003-07-07
Abstract: A method for upward growth of a hydraulic fracture along a well bore sandpacked annulus (60) and over a selected rock formation interval. The interval encompasses a multitude of oil and gas saturated formations and intervening silt and shale formations. Creating a linear sourced, cylindrica l, stress field by maneuvering an intersection of a first and second fluid friction controlled pressure gradients of a face pad fluid (51) through the sandpacked annulus and a hydraulic frac in the adjacent formation interval. The first gradient is created by controlling a fluid flow rate of the frac p ad through a portion of the sandpacked annulus above the top of an upwardly propagating fracture. The first pressure gradient is greater than the averag e gradient of rock formations frac-extension pressure gradient. The second pressure gradient is equal or less than the average frac-extension gradient.

Title: Techniques for correcting for phase and amplitude offsets in a mimo radio device
Inventor: VAIDYANATHAN CHANDRA
IPC: H01Q3/26
Filed: 2003-09-09
Abstract: Techniques are provided to correct for phase and amplitude mismatches in a radio device in order to maintain channel symmetry when communicating with another device using a multiple-input multiple output radio communication.  Correction for the amplitude and phase mismatches among the plurality of transmitters and plurality of receivers of a device may be made at baseband using digital logic in the receiver path, the transmitter path or both paths of that device. Amplitude and phase offsets are determined among the plurality of radio transmitter and radio receiver paths by measuring phase and amplitude responses when supplying a signal to a transmitter in a first antenna path of the device and coupling the radio signal from a first antenna to a second antenna path of that device where the signal is down-converted by a receiver associated with the second antenna path.

Title: Enclosure and method for making an enclosure
Inventor: HOKUM ROBERT T JR
IPC: E04C3/30
Filed: 2005-04-19
Abstract: An enclosure, such as a column for supporting a roof, is defined by plural, adjacent, beveled segments, including two outermost segments, folded and joined. An adhesive is used on the beveled edges to help to hold the shape of the enclosure. In addition, the edges of the outermost segments are configured to interlock so that, with manual force and no tools, the outermost segments can be snapped together, thereby holding the enclosure while the adhesive cures. The configurations on the outermost edges are preferably made of interlocking projections and recesses, at least one of which projections is displaced slightly when the outermost segments are joined. The segments may be formed by milling a single panel while applying tape to the joints between segments to hold them in adjacent relationship. The tape may then be removed after the enclosure is formed. The preferred material for the enclosure is foamed plastic.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.
