Abstract: A lever-action vehicle lift for lifting a from the ground surface. The lift frame defines a vehicle contacting section and a fulcrum section for rotatably supporting the lever frame when the latter is pivoted about the ground surface. A spacing section is solidly attached between the vehicle contacting section and the fulcrum section for maintaining the vehicle contacting section and the fulcrum section in a first predetermined spaced relationship relative to each other. The vehicle contacting section and the fulcrum section are positioned in a common geometrical plane. A lever handle is pivotally attached to the lever frame by a handle pivotal connection so as to allow the lever handle to pivot about a lever pivoting axis extending in the common geometrical plane. The lever frame and the lever handle are configured and sized such that when the lever is in a raising configuration with both a handle ground contacting section and the fulcrum section contacting the ground surface, the common geometrical plane forms an acute angle relative to the ground surface such that the vehicle contacting section is located intermediate and above both the fulcrum section and the handle ground contacting section at a raised distance from the ground surface. The vehicle contacting section is given various configurations for accommodating various motorcycle frame configurations. A handle releasable locking mechanism is also provided for selectively locking the lever handle in a predetermined angular relationship relative to the lever frame.

Patent CA-2285632-A1 (CA)
Title: Method and apparatus for improving power handling capabilities of polymer optical fibres
Inventor: BRENNER DOUGLAS
IPC: G02B6/24
Filed: 1998-01-15
Abstract: The power handling capability of polymer fibers is increased by broadening an input intensity profile, which is typically Gaussian, without significantly decreasing the efficiency of coupling light into a polymer fiber. The method for increasing the power handling capability of polymer fibers includes the steps of: a) emitting light having a Gaussian intensity profile from a fiber light source; b) broadening the Gaussian intensity profile so that energy at the center of the Gaussian intensity profile is distributed to the perimeter to reduce the peak power intensity of the emitted light before it is launched into the polymer fiber; c) transmitting the emitted light into at least, one polymer fiber. Preferably, a fused bundle is used to broaden the intensity profile and preferably the fused bundle has an angled input end face. As a result, more total power can be coupled into the polymer fiber while keeping below the melting threshold caused by the light absorption - enabling, for example, power in excess of 1 Watt to be transmitted through a 1-mm diameter PMMA fiber.

Abstract: A system for simplifying the design of winding guides is provided. The flyer arm of a winder built in accordance with the principles of this invention is positioned so that the extreme delivery point of the wire is aligned and practically over the slots of the armature where the coil is being wound. Additionally, the flyer arm can be easily and quickly substituted on the winder to conform to the armature being wound, ensuring that the extreme delivery point of the wire is aligned and practically over the slots of the armature where the coil is being wound. This feature of the invention contributes to a simpler design of the winding guide. Accordingly, traditional guide surfaces for capturing the wire coming from a distant position are no longer required.

Title: Drive mechanism for oscillatory dental tool
Inventor: POSTAL ROBERT T
IPC: A61C17/00
Filed: 1998-06-18
Abstract: A dental tool assembly (10) having a driving mechanism (28) with inter-engaging cam surfaces (50, 60) shaped for continuous contact during use. 'The mechanism (28) includes a drive shaft (30) having a drive surface (50), and a driven shaft (40) having a driven surface (60). The cam surfaces (50, 60) are shaped, the shafts (30, 40) are transversely juxtaposed with respect to each other such that the drive surface (50), and the driven surface (60) are in continuous contact during the rotation of the drive shaft (30) to impart oscillatory rotation to the driven shaft (40).  Specifically, the drive surface (50) is conical, and preferably has a cone axis (51) that is at an approximately 45 degree angle with respect to the rotation axis (31) of the drive shaft (30). The driven surface (60) has alternating hills (62) and valleys (64). Rotation of the drive shaft (30) causes the drive surface (50) to ride alternately along the hills (62) and valleys (64) continuously in contact with the driven surface (60). When the drive surface (50) moves along a hill (62), the driven shaft (40) is rotated approximately 45 degrees from the rest position, and contact with oppositely positioned hills causing rotation in opposite directions. Oscillatory rotation is thereby imparted to the driven shaft (40) as the drive surface (50) alternately engages the alternating hills (62) and valleys (64).

Patent CA-2297700-A1 (CA)
Inventor: CHENNAKESHU SANDEEP
IPC: H04L1/06
Filed: 1998-07-27
Abstract: A multi-signal cancelling demodulator in which signals of interest are demodulated using information obtained during demodulation of adjacent signals. By utilizing detected information in an across-channel fashion, exemplary cancelling demodulators provide superior adjacent channel interference rejection. The cancelling demodulation is conducted in either serial or parallel fashion. In exemplary parallel demodulation embodiments, two channels are demodulated simultaneously in iterative fashion. Detected information obtained at each step in the iterative process is used as a priori information for demodulation in a following step. In exemplary serial demodulation embodiments, the stronger of two received signals is demodulated, and the resulting detected information is used as a priori information for demodulation of the weaker of the two received signals. For both the serial and parallel demodulation embodiments, novel techniques are disclosed for transforming symbols detected in one frequency band to corresponding symbols in adjacent frequency bands. Such inter-channel transformations are also applied in the context of channel estimation. In an exemplary channel estimator, multiple channel parameter estimates for a particular frequency channel are provided based on a received baseband signal corresponding to that frequency channel. Since inter-channel information is used in providing the channel parameter estimates, the exemplary channel estimator provides superior adjacent channel interference rejection.

Abstract: A rotatable connection system for boom sections has been invented. With the invention, boom sections can be added to a boom being constructed in either a horizontal layout configuration or in a vertical configuration, such as adding a boom section onto a hanging luffing jib boom butt. With the invention, a horizontally orientated boom section can be added to a hanging boom. The coupler of the female connection is placed in the socket of the male connector and the retainer is put in place to keep the male and female connectors coupled. The assembly is then boomed up, the weight of the new section being carried by the coupler. The new section is free to rotate until it also is hanging nearly vertically. The section is then swung into an aligned position and lower connector pins can be inserted to secure the bottom connectors. This method of adding sections and booming up is continued until the desired luffing jib boom length is assembled.
