Patent CA-2240473-C (CA)
Title: Generateur de frequence numerique
Inventor: SHINE THOMAS ADAM
IPC: H02P8/14
Filed: 1996-12-27
Granted: 2005-11-22
Abstract: Dans un procédé de génération d'un signal d'horloge ayant une fréquence désirée, une impulsion est générée chaque fois qu'une valeur mémorisée en accumulateur (<u>réservoir</u>) s'avère être supérieure ou égale à une valeur de <u>déclenchement</u> mémorisée. Dans une première boucle (10), la valeur mémorisée en accumulateur (<u>réservoir</u>) est augmentée de façon itérative d'une première valeur itérative (<u>r</u>) jusqu'à ce que la valeur mémorisée en accumulateur soit supérieure ou égale à la valeur de <u>déclenchement</u> mémorisée et, par la suite, dans une seconde boucle (11) que la valeur mémorisée en accumulateur (<u>réservoir</u>) soit diminuée d'une seconde valeur itérative jusqu'à ce que la valeur mémorisée en accumulateur soit inférieure à la valeur de <u>déclenchement</u> mémorisée. Au cours de chaque itération de la première boucle (10), une fréquence de courant du signal d'horloge est comparée à une valeur de fréquence désirée et si les deux valeurs sont différentes, la première valeur itérative (<u>r</u>) est amenée par correction à une cadence prédéterminée (<u>accRate</u>) sur une des multiples itérations suivantes jusqu'à ce que la fréquence du signal d'horloge du générateur corresponde à la valeur détectée de la fréquence désirée. Dans un exemple préféré, le nombre d'itérations nécessaires pour modifier la première valeur itérative (<u>r</u>) est déterminé par une valeur mémorisée en accumulateur qui est ajoutée à un accélérateur-accumulateur (<u>AccTank</u>) pour chaque itération de sorte que la première valeur itérative et la fréquence désirée ne soient pas exactement égales.

Title: Heat exchanger
Inventor: TSUNODA TADASHI
IPC: F28F3/08
Filed: 1997-10-17
Granted: 2003-02-04
Abstract: In the case where a partition for partitioning a combustion gas passage inlet (11) from an air passage outlet (16) is defined by a plate (8) attached by brazing to end faces of a plurality of heat exchanger plates (S1, S2) in a heat exchanger (2), durability of the brazed portions are prevented from being degraded due to a load F acting on the plate (8) by a pressure differential between a combustion gas and air. Thus a joint substrate (26) is attached by brazing to the end faces of the heat exchanger plates (S1, S2) with the front surface of the joint substrate (26) brazed to the rear surface of a joint flange (28), which is formed by bending an end of the plate (8) by right angles, and a joint flange (27) having an L-shaped cross section is attached by brazing to an underside of the plate (8) and the front surface of the joint substrate (26). Accordingly, the joint portions are increased in rigidity to ease stress concentration, thus enhancing durability.

Title: Intelligent braking system for materials handling vehicles
Inventor: SHERMAN NICHOLAS J
IPC: B60T8/18
Filed: 1998-09-23
Granted: 2008-11-18
Abstract: A computer controlled braking system utilizes gross vehicle weight of a materials handling vehicle and maxi-mum allowable vehicle speeds to calculate braking force in response to a service brake request. For vehicles equipped with a caster brake, the calculated braking force is propor-tionally distributed between a drive brake and the caster brake. The drive brake includes a mechanical brake and motor braking which is performed by a traction motor. The drive brake force is divided between the mechanical brake and the motor braking so that the motor provides as much braking as possible to reduce wear on the mechanical brake and also to conserve battery power. For vehicles equipped with a caster brake, the caster brake portion of the calculated braking force is determined as a programmable percentage of the total braking force and can differ based on travel di-rection. The caster brake portion is clipped and reverts to the drive brake if it is below a minimum; and, if the cal-culated caster brake force is greater than a maximum, the caster brake force in excess of the maximum is clipped and reverts to the drive brake. A maximum caster brake current can be set to accommodate different brake hardware. A user of the vehicle can select adjustments to the calculated drive brake force and,if provided, can also select independent ad-justments to the calculated caster brake force. If the vehicle has not substantially stopped within a given period of time after having its speed reduced to a low speed, the mechanical drive brake is fully applied.

Title: High temperature extraction of spices and herbs
Inventor: TODD GEORGE N
IPC: A23L7/10
Filed: 1998-12-11
Granted: 2008-06-03
Abstract: Principal components of herb or spice plant materials are simultaneously extracted and concentrated in at least one high temperature and pressure mechanical pressing step. The extract may be hydrated and then centrifuged to remove fine particulate solids and gums. A solution having several times the concentration of the pigments and flavor a nd aroma components of the starting raw material is obtained. The residual press solids and extract have significantly reduced bacterial counts as a result of the temperatures, high pressure, and high shear utilized, as well as the low moisture levels employed, thus producing not only a food grade extract but also a food grade residual solid having low bacterial counts and predictable, standardized levels of the principal components of interest. Additionally, edible antioxidants can be included in the process to enhance the stability of both the extract and the residual solids. The residual solids are ruptured in the process, giving rise to a quick-release and enhanced effect, and thus greate r use effectiveness, when the herb or spice solids are used in foods or beverages.

Title: Channel band conversion apparatus for optical transmission systems

IPC: G02F1/37
Filed: 2000-08-03
Granted: 2004-03-02
Abstract: The number of optical channels that may be used to transmit information/data is greatly enhanced using an optical transmission facility having a transmitter that outputs optical signals having respective wavelengths within a first bandwidth, e.g., the C band, combines the latter signal with an optical signal having a wavelength between the first bandwidth and a second bandwidth, e.g., the L-band, and, using a non-linear frequency converter, processes the combined signal to form at least optical signals having wavelengths within the second bandwidth that correspond with the wavelengths of the optical signals within the first bandwidth. In this way, equipment designed for the C band may also be used to process optical signals with another, second band.
