Patent CA-2539422-A1 (CA)
Inventor: HOFMAN RAY A
IPC: E21B43/26
Filed: 2006-03-13
Abstract: A cemented open hole selective fracing system is shown. In the producing zone, an open hole is drilled therein and a production tubing is cemented in place. At preselected locations along the production tubing, the production tubing will have sliding valves located there along. The sliding valves may be selectively opened by a shifting tool, and the cement around the sliding valve dissolved. Thereafter, the formation may be fraced immediately adjacent the opened sliding valve. By selectively opening different combinations of sliding valves, fracing can occur in stages with more fracing pressure and more fracing fluid being delivered deeper into the formation. Just as the sliding valves can be selectively opened with a switching tool, the sliding valves can also be selectively closed to protect the production of the well.

Title: Method for formation of puffed cereal cakes
Inventor: JOHNSON LAMAR
IPC: A21D2/00
Filed: 2004-11-22
Abstract: A method for forming a puffed cereal cake is disclosed. The method includes pre-treating the grain used to make the cake by flash frying it in a flash frying media for a period of time of from 1 to 15 seconds prior to puffing and forming the cake. Preferred flash fry media include an edible oil, shortening, or paraffin at a temperature of from 145 to 205~C. Alternatively, the media can comprise a caustic bath of 1% baking soda and 99% water at a temperature of from 70 to 85~C. The pretreatment allows the formation of a puffed cereal cake with dramatically improved taste and texture. In addition, the pre-treatment permits coatings of seasonings or flavorants to adhere to the puffed cereal cake much better. The puffed cereal cake can have a desirable high fat taste with out actually being a high fat food.

Title: Deep discharge protection for battery packs with cell groups
Inventor: ZIEGLER BERND
IPC: H01M2/10
Filed: 2006-08-22
Abstract: A method of preventing deep discharge of the battery pack (1') with series-connected cell groups (2a, 2b) by polarity reversal of an individual weakest cell (3), includes a difference measurement step which is repeated over time for detecting an event indicative of a probable reversal of polarity in which the change over time of the voltage difference between two cell groups (2a, 2b) having identical numbers of cells is checked to determine if the change in the voltage difference has exceeded an amount corresponding to a difference threshold value which reliably distinguishes a fast polarity reversal of an individual weakest cell (3) in exactly one cell group (2a, 2b) from the slow fluctuation of the voltage difference between two cell groups (2a, 2b) during an ordinary discharge characteristic curve without polarity reversal of an individual weakest cell (3); and a battery pack (1') and a battery-powered hand-held power tool (7) with a monitoring circuit (5') for implementing the method.
Patent CA-2558455-A1 (CA)
Inventor: AUBERT CHRISTIAN
IPC: G09B19/06
Filed: 2004-03-02
Abstract: A method for teaching a foreign language and its verbs conjugations by focusing on understanding first and speaking second to help the student hear and say dialogs the real way natives speak. The student first listens to the conjugation or the text of the dialog read by the speaker the exact way it is generally spoken. The subsequent steps are organized with the idea that to learn well and fast, one needs to exercise each and all of his or her senses.  The senses are taken separately and added one at a time. The hearing sense comes first, then the taste is added on top of it when the student is asked to repeat, then the sight when the students are asked to observe in the text what they are repeating. The sense of touch is then added when for the verbs they practice each tense vertically. The verb is the most important part of the sentence and as they practice the way on the verbs and by extension on entire dialogs, the student will learn to read the way people really speak, not the way they read.

IPC: B01D53/02
Filed: 2005-03-18
Abstract: A disposable dryer cartridge for an air/gas dryer apparatus for installation in an air/gas line delivering compressed air or gas to an air/gas-driven tool.  The cartridge includes a flexible elongated casing having a drying composition therein. The casing has an air/gas inlet and an air/gas outlet thereon. A  handle is also provided on the casing. The casing is self-configurable into a cross-sectionally contracted configuration when lifted by the handle to facilitate insertion in or removal from an air/gas dryer apparatus. Following insertion of the casing in an air/gas dryer, it is manipulated as necessary to reconfigure the casing from the contracted configuration to an operational configuration wherein the casing is not cross-sectionally contracted and wherein the drying composition is compacted. When the casing needs replacement, it can be grasped by the handle and lifted to re-effect the contracted configuration and thereby removed from the dryer.
