Patent CA-2214754-A1 (CA)
Inventor: NARISADA MASATAKA
IPC: A61M1/34
Filed: 1997-09-08
Abstract: If pressure constraints occur during the execution of blood treatment, the pump flow rates are rapidly decelerated to remove the pressure constraints so that the treating operation will restore the normal state as quickly as possible.  After the pressure constraints have been removed, the pump flow rates are restored at a preset acceleration without causing any excessive pressure buildup due to an abruptly increased load.  If the pump flow rates immediately after the start of operation of the processor are increased through two stages of acceleration, the target flow rates can be rapidly reached without exerting any abrupt load on the processor and, hence, without causing an excessive pressure buildup.
Patent CA-2215684-A1 (CA)
Inventor: KANAAN ROGER J
IPC: B25B5/00
Filed: 1997-09-16
Abstract: This invention has as its purpose the provision of a clamp screw in which the loss of clamping force is greatly reduced, a powerful clamping force can be obtained with a small rotational input, a sufficient clamping force can be obtained by a manual operation, and moreover, a sufficient clamping force can be obtained without excessive clamping by making effective use of the reverse thrust of the rotating tool.      With the clamp screw of the invention, when the flange ring is in contact with the object to be attached, the rotation of the threaded member stops and a clamping state is entered, the rotation of the operating ring is screw fed by the balls moving around the thread grooves, and as a result of this movement of the operating ring due to the screw feed, pressure is exerted on the flange ring through the restraining ring thus clamping the tool to be attached.

Title: Trottinette sportive et de transport monoplace et biplace
Inventor: FORTIER RAYMOND
IPC: B62B3/02
Filed: 1998-06-26
Abstract: La présente invention consiste en un appareil dont la base est munie de six (6) roues et qui est propulsée à l'aide d'un coup de pied. Cet appareil est dirigeable puisqu'il est muni d'un guidon dont le conducteur se sert en même temps qu'il transfert son poids dans la direction où il désire aller. Une légère torsion au guidon, soit à droite soit à gauche et un léger transfert de poids fait que cet appareil est capable d'effectuer des manoeuvres acrobatiques très amusantes qui permettent au conducteur de mettre en valeur son équilibre, sa force musculaire pour la rapidité et sa flexibilité pour diriger l'appareil. Les manoeuvres acrobatiques et la facilité de diriger cet appareil sont rendues possibles grâce aux deux roues avant qui pivotent sur 360.degree. et aux deux essieux arrière qui inclinent l'appareil au bon angle de courbure lors des manoeuvres acrobatiques. L'innovation dans cet appareil est qu'il peut transporter un passager (enfant, adolescent, adulte) en toute sécurité puisqu'il est équipé d'un siège fixe et d'un double dossier inclinable pour le confort du dos du passager. Pour une sécurité accrue pour l'opérateur et le passager, un mécanisme de freinage très efficace a été installé. Ce frein permet à l'opérateur de freiner sur une courte distance même si l'appareil roule à vive allure ou grande vitesse. Le frein est appliqué par le pied du conducteur. Cet appareil se replie en enlevant deux (2) boulons seulement, ce qui facilite son transport, soit dans le coffre arrière ou sur le toit d'une auto ou d'une fourgonnette. Une fois l'appareil replié, il occupe une place de rangement moindre dans le placard, garage ou tout autre endroit de rangement dont l'espace est restreint (revendication). Cet appareil est utilisé sur les pistes cyclables en asphalte. Cet appareil, une fois assemblé avec ces différentes composantes, est unique et nouveau à tout point de vue. Une description détaillée de sa construction, de ses composantes et une liste de revendications (claims), et des dessins techniques prouvent sa nouveauté. Référence au mémoire descriptif.

Title: Automatic compression release mechanism for an internal combustion engine
Inventor: BURKE JAMES P
IPC: F01L13/08
Filed: 1998-07-08
Abstract: An internal combustion engine includes a mechanism for releasing compression from the cylinder during starting. That mechanism has an actuator attached to the engine camshaft for sliding between first and second positions. In first position the actuator is engaged by a lifter to open the engine exhaust valve during the compression phase of the combustion cycle. At the second position, the valve lifter does not engage the actuator and the exhaust valve remains closed during the compression phase. A weight lever is pivotally attached to the camshaft and drives the actuator between the first and second positions in response to engine speed. At slow speeds occurring while before the engine starts, the actuator is held the first position so that the compression is relieved. After the engine starts, centrifugal force causes the weight lever to drive the actuator into the second position at which normal compression occurs.

Title: Method for the decentralized control of a motor drive
Inventor: HEESEMANN JUERGEN
IPC: G05B19/4103
Filed: 1997-01-08

Each tree represents, respectively, a definition of a the command, reply or data to which it relates. Each tree includes a root node identified by name, eg. a codepoint. The root node includesinformation describing the type of definition tree concerned (i.e. whether it relates to a command, reply or data), and may include one or more internal or terminal descendant nodes. These nodes represent components of the definition represented by the tree. The descendent nodes include level information describing the level of the node within its tree. The nodes may include attribute information, and may include value requirements relating to transmission information represented by the nodes.
