Patent CA-2262366-C (CA)
Inventor: BAER MARK E
IPC: A47L9/00
Filed: 1999-02-22
Granted: 2007-01-16
Abstract: A motor housing for a vacuum cleaner includes a main body, a peripheral rim, and an interconnecting base bounding portions of a working air chamber. A portion of the peripheral rim defines a sidewall having a plurality of vanes and a plurality of exhaust openings, with the vanes and the exhaust openings cooperating to exhaust air from the working air chamber in response to rotation of the impeller. Each of the vanes having an airfoil-shaped cross section, and each vane is oriented such that the airfoil of each vane is oriented oppositely relative to the airfoil of its adjacent vanes. Thus, a first set of the vanes are positioned to direct air through the exhaust openings, while a second set of vanes are positioned to direct excess air from adjacent the exhaust openings toward the chamber and back into the flow pattern. The excess air is thus smoothly remixed at a different velocity with the air moving through the working air chamber such that synchronization of the air flow is reduced, and harmonic induced noise is minimized.

Granted: 2007-07-17
Abstract: The present invention relates to compositions (deodorizing or not) for human and animal excrement, especially pest and livestock, comprised of acidic agents and water soluble polymers, wherein the acidic agents are base neutralizers for the ammonia and indolic amines in the excrement and the water soluble polymers are barrier forming agents for the vapor of the offensive odor producing compounds in the excrement and for slowing down the air oxidative and enzymatic nitrification of the excrement ammonia and organic nitrogen thus dispersing and attenuating nitrate concentrations in the environnement. The present invention further relates to a method of applying said compositions to excrement. Said compositions may be applied to excrement in liquid form by mixing the liquid composition together with the excrement, or in form of a spray, by spraying the composition directly onto the excrement.

The retainer includes a middle body structure, a pair of side wing structures, an inner seat and an outer seat. The middle body structure has opposite lateral sides, interior portions and exterior portions. The side wing structures are attached to and extend in opposite lateral directions from the opposite lateral sides of the middle body structure. Each side wing structure has exterior portions. The inner seat is defined on the interior portions of the middle body structure. The outer seat is defined forwardly of the inner seat on the exterior portions of the middle body structure and of the side wing structures. The inner optical lens is mounted to the inner seat of the retainer. The middle body structure and side wing structures together define an opening aligned with the inner optical lens and provides an unobstructed forward panoramic field of view through the retainer.

Title: System for inducing tachycardia utilizing near field t-wave sensing
Inventor: ZEIJLEMAKER VOLKERT A
IPC: A61N1/362
Filed: 1999-01-26
Granted: 2004-05-04
Abstract: A system and method are provided for inducing ventricular tachycardia in a patient to enable testing to determine the optimun parameters for anti-tachycardia stimulation. The implantable device provides for overdrive pacing of the heart for a short sequence, followed by delivery of a series of pulse pairs. Each pulse pair has a first stimulus pulse delivered at the same or similar overdrive rate, and an inducing pulse which is delivered in timed relation to the evoked T-wave, preferably during the falling edge portion of the T-wave. In this way, each cycle the inducing pulse is timed for efficaciously inducing techycardia. The timing of the inducing pulse is enhanced by near field sensing of the T-wave at about the location where the pulses are delivered, preferably using bipolar sensing and/or sense circuitry designed to recover the signal with an optimum time response.    In one preferred embodiment, near field sensing is enabled by use of an FDC circuit. In another preferred embodiment, near field sensing is provided by a pacing lead having bipolar electrodes where the ring electrode is spaced less than 1 mm proximal to the tip electrode.
