Patent CA-2381932-A1 (CA)
Inventor: STRATICO GIANFRANCO
IPC: H02K15/095
Filed: 2002-04-17
Abstract: Apparatus and methods for winding wire around the poles and partly within the slots of dynamoelectric machine components, such as stators. Some stators are designed with poles having pole tips that extend relatively far in a peripheral direction, perhaps reaching nearly half way across the stator core. When the pole tips reach so far around the stator core and thus leave little room between opposing pole tips, it may be difficult to use winding technologies with needles that need to move between opposing pole tips. Therefore, stators may be divided into segments for the winding of each pole, and then reassembled to form a complete stator. The segments, are wound by rotating the segment and a wire guide structure about an axis, while providing wire to the rotating apparatus from a wire source.

Title: Orthodontic brackets and convertible buccal tubes
Inventor: HANSON G HERBERT
IPC: A61C7/28
Filed: 2001-09-13
Abstract: New orthodontic devices comprise a bracket or convertible buccal tube, both having a body with an arch wire slot (26) therein. Both have a slot closure member (36), also referred to as a jamming shutter, pivotally mounted for movement between slot open (Fig.2) and closed (fig.1) positions and consisting of a pivot portion (46) including an arm portion (50) with a mesially-distally extending slot closure portion (48) at its end. The slot closure portion (48) has a part that closes the slot and mesially-distally extending parts that in slot closed position (Fig.1) engage an adjacent body surface with an interference jamming fit sufficient to retain the slot closure member (36) in slot closed position (Fig.1). Any movement of the slot closure member (36) to and from the slot closed position (Fig.1) involves flexing of these engaged parts away from the device body against the material elasticity, removing the need for latches or retaining springs. The body or the closure member has a recess (54) to receive an opening tool (58) that is rotated to open the slot.  A bracket will usually be "active", including an attitude controlling spring (64) having a free end (68) protruding into the slot (26). A surface of the pivot portion (46) can be a cam (82) that in slot open position (Fig.2) holds the spring (64) out of the slot (26), facilitating insertion and removal of the wire. In brackets for incisors or canines the labial-lingual dimension decreases progressively from the lingual to the labial; with the slot closed the occlusal surface is unobstructed and forms a bite plane engaged by the cutting edge of the opposed tooth during biting action to oppose overbite. A  convertible buccal tube employs the same basic structure with the slot opening at an appropriate surface; the slot closure member (36), and a spring (64) if provided, are similarly mounted in the body.

Patent CA-2389923-A1 (CA)
Title: Intraocular lens system
Inventor: BANDHAUER MARK H
IPC: A61F2/16
Filed: 2000-10-25
Abstract: An accommodating intraocular lens system including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more haptic elements. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more haptic elements. Each haptic element is formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis.      The accommodating intraocular lens system is so designed with specific flexibility characteristics to facilitate axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force. Through the axial displacement of the positive optic portion with respect to the negative optic portion, accommodative effects are maximized to achieve multi-distance visual imaging.

Title: Method of improving steering performance robustness utilizing dimensional non-uniformity in tire/wheel
Inventor: MICHEL EDOUARD
IPC: F16F15/32
Filed: 2002-07-03
Abstract: The invention relates to methods for improving vehicle steering performance and robustness of that performance through control of non-uniformities in the vehicle's tires, wheels and tire/wheel assemblies as a way to overcome the tendency of the steering systems in certain vehicle types to undergo "steering performance loss." While minimizing lateral force variations (e.g., couple imbalance), a controlled amount of radial and/or tangential force variation is induced in one or more tire/wheel assemblies by means of mass non-uniformity, dimensional non-uniformity, and/or stiffness non-uniformity. For dimensional non-uniformity, the preferred method comprises imparting a controlled amount of dimensional non-uniformity (preferably radial runout) to the tire and/or the wheel in at least one of the tire/wheel assemblies, followed by statically and dynamically balancing all of the vehicle's tire/wheel assemblies. All tire non-uniformities imparted according to the invention are preferably distributed meridionally symmetrically about the equatorial plane of the tire, so as to induce tangential and/or radial force variations but not lateral force variations. Similarly, wheel non-uniformities must be symmetric about the equatorial plane of the wheel. Beneficial tangential and/or radial force variations will result from the operation of tire/wheel assemblies prepared according to the invention, even if the tire/wheel assemblies are balanced by weights added to the wheel.  Synergistic beneficial effects result from combinations of the various forms of beneficial mass, stiffness, and dimensional non-uniformity.

The cladding layer can be on one or both surfaces of the core layer. The thickness of the cladding layer can range between about 2.5 and 40 % of the overall composite thickness depending on whether one or more cladding layers are employed. The cladding layer also has a corrosion potential more negative than the core layer for enhanced corrosion resistance.

Title: Methods for removal of impurity metals from gases using low metal zeolites
Inventor: BHADHA PAUL M
IPC: B01D53/26
Filed: 2001-04-02
Abstract: A zeolite having a high silica-to-alumina ratio is heated to about 400~C to remove physically adsorbed water, followed by heating to in excess of about 650~C, to form a superheated dehydroxylated zeolite. The zeolite is used to adsorb trace moisture from a feed gas. The zeolite can also be prepared having a low level of metallic impurities by contacting the zeolite with an acid gas.  This zeolite is particularly useful for removing trace metal impurities from acid gases such as hydrogen chloride and hydrogen bromide.
