Patent CA-2545072-A1 (CA)
Inventor: MODHA SHANTILAL HIRJI
IPC: A61F6/04
Filed: 2004-07-06
Abstract: An elastomeric article (e.g., glove, condom, and so forth) coated with a hydrogel is provided. The hydrogel coating facilitates dry and/or damp donning. In addition, due to its low coefficient of friction, the hydrogel allows stripping of a dip-formed article without the use of an antiblocking powder. Thus, the present inventors have discovered that certain treatment steps, such as chlorination and./or lubrication, conventionally conducted "off-line" (i.e., after stripping) are no longer required. Moreover, even when such treatments are used, they may conducted "in-line" (i.e., before stripping).  The ability to eliminate certain off-line treatment steps provides a significant improvement in the efficiency of the forming process.

Title: Electrically enhanced in situ remediation of contaminated soil
Inventor: POOL WIEBEREN
IPC: B09C1/06
Filed: 2003-12-04
Abstract: During in situ electroremediation of soil electric fields generated by electrodes (10, 12) that are located in the soil are used to move contamination, complexing agents, chemical reagents and/or nutrients through soil or to heat the soil. Control of the voltages and/or currents on or through the electrodes (10, 12) is used to prevent electrode clogging problems, to reduce unnecessary power consumption and/or to prevent boiling. In one aspect (electrokinetic remediation and electro heating) the current through selected electrodes (10, 12) is temporarily stepped down if the onse t of clogging and or boiling is detected from an increase in the electrical resistances from an electrode into the soil. Preferably an effect of soil resistivity changes on the detection is removed by using sensing electrodes (14a, 14b) in the soil. In another aspect (elektrokinetic (bio) fence / screen) the voltage or current is adapted dependent on measured groundwater flow speed changes, so that the method remains effective with minimum power consumption. In yet another aspect (electrokinetic phyto remediation) polari ty reversals of the current are timed using cumulative current measurements.</S DOAB>

Title: Method for determination and quantification of radiation or genotoxin exposure
Inventor: D ANDREA ALAN
IPC: C07K14/47
Filed: 2005-01-28
Abstract: The present invention discloses methods for detecting exposure of a living subject to genotoxic agents, testing sensitivity to a genotoxic agent, and determining DNA damage caused by exposure to an agent, comprising detecting the presence of FANCD2-containing foci from a sample collected from said subject. The presence of concentrated foci is indicative of DNA damage, and the degree of foci formation is correlated with degree of exposure. Diagnostic reagents contain a ligand that binds to human FANC~2 associated with a detectable label, Kits for detecting DNA damage in a biological sample contain such diagnostic reagents and signal detection components. The invention further discloses methods for identifying agents which modulate the ability of ~ANCD2-containing foci to form. Among other things, such agents are potentially useful chemosensitizing agents or may confer protection against damage caused by genotoxic agents.

Title: Method and apparatus of producing belts with precise cord length and tension
Inventor: WOOD DOUGLAS BRUCE
IPC: B29D29/00
Filed: 1996-10-03
Abstract: A method and apparatus for accurately applying a cord (12) to a rotatable mandrel (14) utilizes control of cord length, rather than cord tension, as the control parameter. The apparatus includes a mandrel (14) with an inflatable diaphragm (54) mounted on an outer surface of the mandrel (14). The diaphragm (54) is selectively inflatable via a control valve (58) and source of pressurized fluid for dynamically adjusting a circumference of the mandrel (14) in response to a control input. The control input reads a tension in the cord (12) being wound. The cord (12) is positively fed to the mandrel (14) according to a defined algorithm based on the mandrel's shape, circumference and rotational speed, rather than by demand feed of the cord (12). The apparatus includes a positive feed control capstan (18) which is electronically geared. The apparatus further includes a cord-laying wheel (30) which isolates radially directed forces from circumferentially-directed forces. A second embodiment of the invention includes the belt being rotated on first and second pulleys (14A, 14B) while the cord (12) is applied. A center distance between the first and second pulleys (14A, 14B) is selectively adjustable to control cord tension in the cord (12).

Filed: 2001-07-19
Abstract: A method and apparatus are disclosed for deinterleaving expanded interleaved data blocks, particularly for use in a wireless telecommunications system such as provided by the Third Generation Partnership Project (3G) standard. The data is processed on a sequential element basis where each element has a pre-determined number of bits M which bits are contained in a block of sequential data words W'. The elements are extracted from the block of words W' in sequential order, each element being extracted from either a single or two sequential interleaved words within the set of words W'. The elements are stored in selective location within a set of words W of a deinterleaver memory such that upon completion of the extraction and writing of all the elements, the words W from the deinterleaver memory can be sequentially read out to correspond to an original data block of bits from which the block of interleaved elements was created. Additional conventional processing results in the contraction of the deinterleaved expanded words to reproduce the data block of bits in a receiver as originally designated for transmission in a transmitter.

Title: Magnetic pulse pump/compressor system
Inventor: CADDELL RICHARD W
IPC: F04B45/067
Filed: 2005-12-09
Abstract: A magnetic pump system includes a ring shaped electric magnet that when pulsed with high voltage and high current, causes a magnetically deflectable elastic member to collapse over a mandrill with an arcuate outer surface. The volume between the arcuate outer surface and the inside of the elastic member is reduced causing compression and expulsion of the fluid therein through a discharge of a one-way passage system. When the magnetic field subsides, the elastic member regains its shape drawing fluid in through an inlet to the one-way passage system.
