Patent CA-2341405-A1 (CA)
Inventor: MORT PAUL R III
IPC: C11D3/10
Filed: 1999-09-03
Abstract: A continuous process for preparing granular detergent composition including a first step of dry neutralizing an acid precursor of an anionic surfactant with a particulate water-soluble alkaline material in a high speed mixer for a mean residence time of about 0.2 to about 50 seconds, thereby partly or totally neutralizing the acid precursor and producing a dry neutralized material containing the anionic surfactant, in the form of a free-flowing powder; and a second step of agglomerating the free-flowing powder into a detergent agglomerate using an agglomeration binder. The agglomeration binder is preferably a viscous sufactant paste binder. The resulting agglomerates are dry, free-flowing, and have a substantially more narrow particle size distribution, compared to the free-flowing powder, with reduced fine particles and over-sized particles that generally are recycled.

IPC: B60K15/077
Filed: 2001-05-08
Abstract: A pair of solid state pressure sensors are disposed near the bottom of a fuel tank vertically spaced with one a unit distance above the other. A third solid state sensor is disposed in the tank at the highest point under the upper wall. The apparent hydrostatic pressure is computed from the difference in pressure sensed by the highest and lowest sensors. The density is computed from the difference in pressure sensed by the pair of sensors near the tank bottom; and, the difference normalized for the vertical distance therebetween. The liquid level height is then computed from computed density and apparent pressure. The reserve volume of liquid fuel is then found for the computed height from a lookup table of values of liquid height and corresponding liquid volume.

The control system (314) determines an available modem from the set of modems when one of the subscriber units is activated. Further, the control system (314) directs the switch (308) to connect the activated subscriber unit (304) with the available modem (310), retrieves from the database (317) authentication information associated with the activated subscriber unit, and provides the available modem (310) with the retrieved authentication information. In this manner, the authentication information associated with the activated subscriber unit (304) is provided to the modem (310) that is handling the call. Consequently, the modem handling the call can transparently authenticate the subscriber unit in the same manner as in a conventional wireless communication service.

Patent CA-2363625-A1 (CA)
Title: Optical switch
Inventor: TSIBOULIA ANDREW
IPC: H04J14/02
Filed: 2001-11-20
Abstract: The present invention provides an optical switch or a large scale fiber-optical cross-connect switch wherein the light from the grouped input fibers is collected by a lens, a lens system, or mirror system, and imaged with a certain magnification to a plane. The plane is either a mirror when the system is operated in reflection, or a plane of symmetry when the system is operated in transmission. Before reaching that plane, the spatially separated beams are intercepted by a (1 or) 2-D micro-mirror input MEMS array, where each mirror can deviate its dedicated input beam to any mirror on the output MEMS array. Each mirror on the output MEMS array compensates for angular tilt and deviates the beam to its dedicated output fiber.

Title: Transfer of shear-thinning slurries
Inventor: PARADIS RONALD
IPC: B01D21/24
Filed: 2000-03-15
Abstract: A method of and apparatus for removing a slurry having shear-thinning visco-plastic rheological properties from a reservoir containing a body of the slurry of such high viscosity that removal is impractical by conventional means, such as gravity flow or suction. The method comprises creating a region of shear-thinned slurry in a submerged part of the body of slurry to entrain adjacent slurry of high viscosity, and then removing a portion of the reduced viscosity slurry permanently from the reservoir. The region of shear-thinned slurry may be produced by recirculating slurry from a submerged part of the reservoir and subjecting it to high shear before returning it to the reservoir to create a flow of slurry of reduced viscosity through the body. The apparatus provides conduits and a shear-generating device communicating with the reservoir and an outlet conduit for slurry permanently withdrawn from the reservoir.

Title: Completely flexible keyboard matrix
Inventor: LU J J
IPC: H01H13/70
Filed: 2002-02-13
Abstract: This invention is about completely flexible keyboard matrix (flexible keyboard matrix), which enables production of keyboard on pulp and fabric materials such as paper or cloth. The major improvements over conventional keyboard matrix are in two major areas. 1) The metal sheets or wires, used to be planted in the matrix, are replaced by metal chains; 2) The flexible keyboard matrix is self-contained with "pressing units", which can generate electronic pulses without attaching external plastic keys to intensify pressure to the matrix. These two changes make it possible to manufacture computer data input device by textile industry in the form of more environmental friendly disposable goods such as paper or cloth. More importantly, the new flexible keyboard matrix makes it possible for seasoned computer users to enjoy comfort and familiarity of keyboard when working with small computing units such as cell phone and PDA.   They can fold data input devices into pocket-sized packages and carry around anywhere to enjoy well-trained typing skills and speedy data entry. Stripping away plastic components now required to interact with conventional keyboard matrix, such as plastic keys and frames, also save materials and lower manufacturing costs.

Title: Split pressure ring for lancing device and method of operation
Inventor: FLORA BRUCE A
IPC: A61B5/15
Filed: 2002-02-28
Abstract: A pressure ring for a lancing device for holding open a skin puncture while collecting a blood sample includes a col-lar that fits onto the end of a lancing device. A skirt is provided on the collar and a flared portion depends from the skirt. At least one axial slit is formed in the skirt. The pressure ring is made of a flexible material such as polypro-pylene such that when the lancing device with a pressure ring is placed on a person's skin and pressure is applied, the slits spread apart stretching the skin for a puncture by a lance in the lancing device. Once a puncture has been made, the pressure ring holds the puncture wound open to allow bleeding. Removing the lancing device from the puncture site releases the skin allowing the puncture would to close.

Filed: 2000-08-16
Abstract: The amount of D-hordein, which constitutes gel proteins, formed in barley is  decreased. The decrease in the D-hordein yield causes not only a decrease in  the gel proteins due to the decrease in the D-hordein fraction in the gel proteins but also the migration (decrease) of proteins other than D-hordein,  which constitute the gel proteins, from the gel proteins. Accordingly, a decrease in the D-hordein yield in barley and, in its turn, a decrease in th e gel proteins can be achieved by transferring a D-hordein expression regulato ry vector 1, whereby the D-hordein yield can be regulated, into barley to there by transform the barley.
