Abstract: A hockey stick blade tool comprises a base and a pair of clamp assemblies mounted to the base.   One clamp assembly is fixed to the base with the other being movable along the base length.   To remove a blade,  the shaft of a hockey stick is clamped in the fixed assembly and the blade is clamped in the movable assembly.  The movable assembly is translated along the base  in  a  direction  away  from  the  fixed  clamp  assembly  to withdraw  the  blade  from the  shaft.   The  base  also  includes provision to provide heat during blade removal.  The base has a pivotal cover which encloses the joint area between the blade end and the shaft end.  A source of heat can be directed underneath the cover to heat the joint area to facilitate blade removal.

Title: Methode d'affectation de canaux dans un systeme de communication mobile a acces multiples par repartition dans l'espace
Inventor: PIOLINI FLAVIO
IPC: H04B7/24
Filed: 1998-11-03
Granted: 2002-07-09
Abstract: Dans un système de communication mobile à accès multiple par répartition dans l'espace fonctionnant en mode d'utilisation simultanée de canaux, le canal à affecter à un terminal est choisi après une évaluation du coût de l'affectation de chaque canal déjà en cours d'utilisation. Ce coût est fonction du temps écoulé moyen entre deux affectations de canal successives au terminal en cause et permet de déterminer le canal où ce temps peut être maximisé. L'évaluation se fait au moyen de coefficients de coût qui tiennent compte de la topologie de la cellule et de la mobilité des terminaux et qui sont déterminés dans la phase d'initialisation du système par une subdivision de la cellule en secteurs et par la détection des instants de collision entre les terminaux.

Title: Integrated multi-wavelength transmitter
Inventor: AMERSFOORT MARTIN R
IPC: G02B6/34
Filed: 1998-01-15
Granted: 2002-06-04
Abstract: An integrated multi-wavelength transmitter comprising an arrayed waveguide grating with feedback channels (32) between two coupling regions (34, 36). The multi-wavelength signal from a first coupling region (34) is reflected from a mirrored surface (54) back into the first coupling region and the arrayed waveguide grating, the mirrored surface thus forming one end of an optical cavity. Each single-wavelength output from second coupler (36) is split up into one part until it passes through a gain region (52) and is reflected back from the mirrored surface (54) whereas a second part passes modulator (58) and enters the first coupler. The multi-wavelength signal (42) from the second coupling region is the output (58) of the transmitter and contains the modulated carriers for all wavelengths.

Patent CA-2279540-C (CA)
Inventor: BOYD JOHN H
IPC: H02P6/18
Filed: 1998-02-05
Granted: 2004-11-02
Abstract: An electronically commutated brushless DC motor primarily for fractional horsepower applications of the type where at any instant one motor winding is unpowered and used to detect back EMF zero-crossings which information is used to initiate winding commutations. The duration of the pulse produced in this winding due to dissipation of stored energy by free-wheel diodes in parallel with the commutation devices after supply of current has been removed from this winding is used to provide a measure of motor current. This allows for simplified commutation device current limiting circuits and is available for control purposes which are a function of motor torque. There is also disclosed a method for maximising useful power output by reducing the phase angle between the motor current and the back EMF. This is accomplished by introducing a delay in commutating the motor windings beyond the occurrence of each back EMF zero-crossing, with the delay being a function of the time between commutations.

Title: Method for decomposing bromic acid by photocatalyst and apparatus therefor
Inventor: KAGAMI RIE
IPC: A62D3/00
Filed: 1999-09-07
Granted: 2005-05-31
Abstract: The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions a photocatalyst adapted to be brought into contact with the liquid in the first section and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions.      The photocatalyst may be at least one metal oxide including titanium and a metal having an electronegativity lower than that of titanium. In this case, it is possible to omit pH adjustments of the liquid before and after the photocatalytic reaction.

Abstract: An automated beverage brewing system includes a liquid storage tank and a metering chamber. The metering chamber is at least partially submerged beneath a standing level of liquid in the storage tank. The chamber includes a sealable liquid inlet port communicating with the interior of the storage tank beneath the standing level of liquid. The chamber also includes a liquid outlet port and an aperture that receives compressed air, wherein the compressed air forces a predetermined amount of liquid from the liquid output port of the chamber for use in preparing a brewed beverage. A pump provides the compressed air and a controller monitors a pressure signal value indicative of the air pressure in the metering chamber. The controller commands the pump on to commence flow of the predetermined amount of liquid from the metering chamber. The controller then commands the pump off several seconds after detecting a drop in air pressure within the chamber, indicating that the predetermined amount of liquid has been delivered to the brewing chamber. The chamber is then vented to ambient pressure, which opens the sealable liquid inlet port and refills the chamber.

Abstract: An apparatus for exercising a hand of a user allowing a full range of motion of the hand during use. The hand exerciser includes a dorsal wrap releasably secured about a wrist of the user and extending over a back side of the hand. A finger power band releasably engages the dorsal wrap and extends over at least one finger of the hand of the user providing a resistance to movement of the at least one finger. A thumb power band is also releasably engaged with the dorsal wrap and extends along a surface of a thumb of the hand of the user providing a resistance to movement of the thumb. The finger and thumb power bands move independently of each other allowing exercise of any of the entire hand, any individual finger or thumb and any combination thereof. Furthermore, the resistance provided by the finger and thumb power bands is adjustable based upon the strength of the user. Finger and thumb power bands having variable resistance levels may be interchangeably connected to the dorsal wrap as desired. On an end of both the finger and thumb power bands opposite their respective connections with the dorsal wrap is a finger receiving cup for receiving a finger of the user and aiding in retaining the hand exerciser in position on the hand. The finger and thumb power bands are color coated, the color of the finger and thumb power bands indicating the amount of resistance provided thereby. The resistance level of the finger and thumb power bands are rated on a scale system having a range of values, each value within the range being representative of a resistance level.
