Patent CA-2164446-A1 (CA)
Inventor: FOURNIER REAL
IPC: F24C15/00
Filed: 1995-12-05
Abstract: Il n'existe aucune cuisinière électrique qui soit munie d'un système intégré capable d'assurer le brassage automatique des liquides (sauces, potages, soupes, lait, eau, etc.) simultanément à leur cuisson ou leur réchauffage. Les seuls appareils ménagers capables d'exécuter cette fonction sont des appareils électroménagers mobiles munis d'un élément chauffant et d'une hélice entraînée par un moteur électrique dont l'arbre traverse, d'une manière ou d'une autre, le fond du récipient contenant le liquide. Un autre type d'appareil de ce genre consiste en un agitateur mobile qui se suspend sur un récipient de cuisson. Dans la présente invention, la surface de cuisson de la cuisinière électrique est équipée d'un agitateur automatique à entraînement magnétique intégré. L'ensemble est constitué d'un moteur électrique entraînant un bloc aimanté placé sous un des éléments de la surface de cuisson de la cuisinière électrique. La vitesse de rotation du moteur est contrôlée par un rhéostat monté sur le tableau de commande de la cuisinière. Une barre agitatrice aimantée recouverte de téflon ou d'une matière plastique est placée dans le récipient contenant le liquide. La rotation du bloc aimanté sous l'élément de surface entraîne la barre agitatrice aimantée qui pivote sur elle-même dans le récipient, induisant un mouvement circulaire dans la masse liquide. Ce mouvement assure le brassage automatique du liquide.

IPC: B41J2/07
Filed: 1996-10-31
Abstract: A detection technique comprises a plurality of closely spaced, continuous detection electrodes placed immediately below and along the length of a charge plate in an ink jet printing system.  The detection electrodes typically comprise parallel conductors.  A circuit is provided for monitoring the conductivity between the electrodes. The electrodes are electrically isolated from one another when properly placed on the catcher surface.

Title: Fluid transfer device and method of use
Inventor: LOPEZ GEORGE A
IPC: A61J1/20
Filed: 1995-06-26
Abstract: A fluid transfer device comprising a hollow piercing element having a first end for receiving a standard syringe nose or other similar medical device and a second end having a tapered tip for accessing fluid inside a medication container is disclosed. In a preferred embodiment, the device has a disk-shaped stop for limiting entry of the piercing element into the vial. Preferably, the piercing element includes outwardly extending barbs which allow the device to be inserted into a vial but which prevent the device from being removed from the vial after insertion.  After the syringe is disengaged from the device, the device and spent medication vial may be discarded as a unit. Alternatively, the device can remain attached to the vial, and a new syringe can be used to withdraw additional fluid from the vial when desired.  In an alternate embodiment, a reusable, resealable valve is connected to the first end of the piercing element, which valve allows multiple syringes to be used with the piercing element. Various adaptors for using the device with intravascular (IV) lines and drip-bags are also disclosed.

Title: Wave energy generator
Inventor: VOWLES GERALD JOHN
IPC: F03B13/18
Filed: 1997-01-29
Abstract: An apparatus and method as seen in Fig.2 for converting the motion of waves on a body of fluid 52 into useable energy. This apparatus employs a wave follower 20 to track the rising and falling waves.      The reciprocating wave follower interacts with a driven device, such as a pump 202a or generator 202b through an optional lever arm 171 and also through a drive member such as a reciprocating shaft 26. Because the driven device is incorporated into an essentially immovable floating or fixed support member 17, work is accomplished. By increasing the work producing travel distance of the driving member, being the wave follower 20 beyond that of previous art and, in certain embodiments such as that shown in Fig.2, and by more effectively capturing surge forces that has previous art, this apparatus is intended to produce significantly more work than other similar devices operating in the same waves.
