Patent CA-2657658-A1 (CA)
Inventor: WELLS MICHAEL P
IPC: F16L35/00
Filed: 2007-07-19
Abstract: A coupling assembly having male and female coupling members that are connectable and separable from each other. The coupling assembly utilizes a resiliently expandable locking element, which is provided on the male coupling member, to connect the male and female coupling members together by trapping the locking element, in its expanded position, between respective locking surfaces of the male and female coupling members. A locking sleeve, which is movable between unlocked and locked positions, is employed to move the locking element to its expanded position. In this position, the locking element prevents the withdrawal of the male coupling member from the female coupling member by creating a positive lock therebetween. To maintain the locking sleeve in its locked position, a retainer can be used.

Title: A cost effective system for supplying solar electricity to both an extended range electric vehicle and a nearby building
Inventor: FREEMAN BENJAMIN
IPC: B60L8/00
Filed: 2009-06-05
Abstract: The present invention is a system for supplying a long range electric vehicle and a nearby building with electricity from the sun in a cost effective way. Not only is the overall system totally efficient in the sense that virtually all solar electricity generated will be used, but the tilting solar roof that tracks the sun is a more efficient way to generate electricity than the normal method of putting stationary solar panels on a building's roof. Similarly, the car contemplated in the present invention will be able to achieve a far longer daily range than similarly priced electric cars. Because of the synergistic approach used, the overall system can play a significant part in weaning the world away from fossil fuels without creating huge costs that cash strapped consumers can't bear.

Title: Characterizing an earth subterranean structure by iteratively performing an inversion
Inventor: ABUBAKAR ARIA
IPC: G01V3/38
Filed: 2008-06-17
Abstract: To characterize an earth subterranean structure using a measurement assembly including electromagnetic (EM) receivers and one or more EM sources, measured voltage data collected by EM receivers in response to transmission by one or more EM sources is received. Based on a model, predicted EM data is computed. Inversion is iteratively performed according to a function that computes a difference between the measured voltage data and a product of a term containing the predicted EM data and a term containing distortion data that accounts at least for distortion effect by an environment of the measurement assembly. The inversion is iteratively performed to solve for parameters of the model and the distortion data.

Abstract: A percutaneous and minimally inva-sive instrument for inserting an interspinous process spacer into a patient is disclosed. The instrument in-cludes a first assembly connected to a handle assem-bly.    The first assembly includes an inner shaft located inside an outer shaft and configured for translational motion with respect to the outer shaft. The relative translational motion causes one of the outer or inner shafts to move with respect to the other and thereby deflect at least one prong formed on one of the inner or outer shafts wherein such deflection causes engage-ment with a juxtapositioned interspinous spacer. The instrument further includes a driver configured for re-movable insertion into a proximal end of a passage-way of the instrument. The driver has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for deployment of the spacer from an undeployed configuration to a de-ployed configuration and vice versa.

Abstract: The rotor has, connected with the hub (1), at least two horizontal supports (2) on the ends of which are rotor blades (3) of a symmetrical and concavo-convex aerodynamic profile with the chord lengths (b1, b2) and the thickness of the profile diminishing towards both wing ends (3a, 3b). The upper wing (3a) and the lower wing (3b) of the rotor blade (3) are radially deflected from the central zone (3c) outwards. The length of the chords (b2) of the profile of both wing ends (3a, 3b) and the chord length (b1) in the central zone (3c) are approximately inversely proportional to the radii of its location in relation to the axis of the rotor's rotation. The deflecting angle of the lower wing (3b) can be greater than the deflecting angle of the upper wing (3a) or the length of the lower wing (3b) can be greater than the length of the upper wing (3a). The specification of the rotor gives a uniform intensity of consuming wind power at the length of the wings and generally in the support only tensile stress is generated while the
