Patent CA-2238384-A1 (CA)
Inventor: STAUB RENE
IPC: B42D15/10
Filed: 1996-11-14
Abstract: An optical information carrier (1) is in the form of a composite laminate (2) having a carrier foil (3). The underside (4) and the top side (5) of the carrier foil (3) are provided with optically effective structures (6; 7). The carrier foil (3) is approximately transparent for light in a predetermined spectral range. The structures (7) allow light impinging on the top side (5) to penetrate at least partially into the composite laminate (2). The structures (6) on the underside (4) are microscopically fine relief structures (10) which are covered with a base layer (8) whose refractive index differs from the refractive index of the carrier foil (3) in at least a portion of the electromagnetic spectrum so that the structures (6) on the underside (4) at least partially reflect and diffract the light (11) which has penetrated into the composite laminate (2). The structures (7) on the top side (5) in turn modify the diffracted light (18). The interplay of the two structures (6; 7) provides manifold characteristic optical effects such as moiré effects and light guide effects. It is also possible in that way to produce optical storage means, retroreflectors and other security features, being well protected from foreign access.

Patent CA-2252135-A1 (CA)
Title: Control system for coverings for architectural openings
Inventor: COLSON WENDELL B
IPC: E06B9/322
Filed: 1998-10-27
Abstract: A control system for a vertically moveable covering for an architectural opening includes a uni-directional drive assembly that is operated with a single pull element such that upon pulling of the pull element, the covering can be raised in increments. A clutch/brake assembly selectively prevents the covering from dropping by gravity between pulling strokes on the pulling element, but a release of the brake allows the shade to drop by gravity from its retracted position to any degree of extension. A governor is further provided to regulate the rate at which the covering drops by gravity. A cord lift system which is operated by the main drive assembly and the clutch/brake assembly includes a rotatable and axially slidable spool about which a lift cord can be wound. The lift cord has one end anchored to the spool and its opposite end extended through a supporting bracket for the spool and downwardly through the covering where the opposite end is anchored to a bottom rail such that a wrapping of the lift cord about the spool lifts the bottom rail thereby causing the covering to be raised adjacent to the lift spool. The lift cord is tangentially fed to the lift spool and forced into an angular wrap on the spool while an outer shell spaced a small distance from the spool prevents multiple wraps so that the lift cord does not become tangled. A return spring biases the spool in one direction to facilitate a controlled movement of the covering from a retracted to an extended position.

Patent CA-2257311-A1 (CA)
Inventor: HARTER DAVE
IPC: A47J27/62
Filed: 1997-06-03
Abstract: A unique instant-on feature for a cooking device that allows microprocessor (26) control of the device after a period of idling. When activated, the instant-on enabler switch (16) sends a signal to the microprocessor (26), which checks an internal clock to determine the amount of time the device has remained idle since the last cook cycle. This information is sent back to the instant-on enabler switch (16), which then selects among an appropriate array of cooking times. These times, longer than the initial pre-set cooking time, are based on testing and compensate for the degree of heat zone stratification in the cooking medium or surface caused by the extended idling. The instant-on enabler program immediately supplies additional heat to the cooking surface upon activation cooking cycle or operator input, allowing the maximum time for the cooking surface to reach proper cooking temperature.

Patent CA-2269096-A1 (CA)
Inventor: TREMBLAY JACQUES P
IPC: A61K35/12
Filed: 1997-10-17
Abstract: La présente invention concerne un procédé de traitement préalable de cultures de myoblastes de donneur sain à l'aide de facteurs de croissance ou de facteurs trophiques, tels que le facteur de croissance de fibroblaste basique (bFGF), et de la concanavaline A, lesdites cultures étant ensuite transplantées sur des sujets souffrant de dystrophie musculaire telle qu'une myopathie. Grâce à ce procédé, les muscles du receveur contiennent une proportion plus élevée de cellules fonctionnelles, dont le nombre est multiplié par quatre; cela est attesté par une incidence plus importante des fibres dystrophino-positives, de sorte qu'il n'est pas nécessaire de préconditionner les muscles du receveur par irradiation ou administration de toxines. Les sujets receveurs ont subi un traitement immunodépresseur à base de FK 506. Lorsque les myoblastes ont été cultivés pendant une période allant de deux à quatre jours, avec 20  mu g/ml de concanavaline A ou 100 ng/ml de TPA, la migration des cellules du donneur vers les tissus récepteurs a été multipliée par 3 ou par 4. On peut en déduire que lors de l'utilisation des cultures primaires, les fibroblastes sécrètent des métalloprotéases, ce qui provoque une dégradation plus importante de la matrice extracellulaire. Tant les métalloprotéases que le bFGF apparaissent bénéfiques pour le succès de la transplantation. L'invention concerne également l'utilisation de métalloprotéases de recombinaison exprimant les myoblastes.
