Title: Double urgence
Inventor: CHOUINARD ROMEO
IPC: G08B17/00
Filed: 1996-03-04
Abstract: Dans la protection contre de feu, l'utilisation d'un avertisseur ou détecteur de fumée est recommandé voir réglementé, le plus courant étant celui à batterie 9 volts. Dans la présente invention dite "doubles urgences" il s'agit d'un nouveau type de protection contre le feu. C'est une amélioration de l'avertisseur de fumée en le combinant à une lampe de de secours. Ces deux systèmes de protection travaillent de paires par l'apport inventif d'un transfert d'énergie ou d'alimentation. C'est-à-dire qu'il y a élimination de la nécessité d'une batterie d'alimentation (9 volt) dans un avertisseur de fumée puisque celui-ci fonctionne en tout temps avec le courant alternatif (110 volts) de la lampe de secours ou de sa batterie rechargable en cas de panne de courant. La problématique actuelle visée est la présence d'un avertisseur de fumée qui ne fonctionnne pas lors d'un moment crucial, fondamentalement à cause d'une batterie d'alimentation déchargé ou encore absent. En réunissant ainsi ces deux dispositifs d'urgences de façon nouvelle, utile voir même essentielle, on s'assure à la fois d'une protection double et accrue contre le feu puisque l'invention est garantie de fonctionner 365 jours et 6 heures par année.

Title: Internal combustion engine having oxygen sensor with reference criterion calibration
Inventor: TEBBUTT IAIN JOHN
IPC: G01N27/406
Filed: 1996-04-29
Abstract: An internal combustion engine has an engine unit fuelled by fuel gas through a carburettor, and also an exhaust pipe comprising a catalytic converter and an oxygen sensor or lambda cell of zirconia incorporating a platinum electrical resistance heater in a bridge circuit having a control resistance and fixed resistances.      For calibration the cell is initially operated in atmospheric air with an heater power control circuit supplying variable d.c. power output, under control of a microcontroller, to the bridge to power the heater and vary the temperature of the cell.      When the cell gives an electrical output of a predetermined reference value this is observed by the microcontroller which varies the value of the control resistance to a calibrating value RC2 at which the bridge nulls. Then the microcontroller is instructed to adopt operating mode and in accordance with its program the microcontroller sets the resistance value of the control resistance at the control value RC1 correlated by an operating function in the program with the calibrating value RC2. The values of the fixed resistances are RA and RB respectively. When the cell is placed in the exhaust pipe and control means comprising the microcontroller and the heater power control circuit is operated, the bridge circuit receives d.c. power from the heater power control circuit to raise the temperature of the cell 10 until the equality   is satisfied, by the value of the heater resistance RH varying with temperature. At satisfaction of the equality, the bridge circuit nulls when the heater resistance RH has the value RH1. This is observed by the microcontroller which varies the power output of the heater power control circuit to hold the temperature of the lambda cell substantially constant by maintaining the heater resistance at its value RH1 to maintain nullity of the bridge circuit.

Abstract: A headrest folding apparatus is disclosed for use in a vehicle seat of the type having a fold-down seatback panel and a headrest. The headrest folding apparatus is operable for permitting the vehicle operator to release a headrest latch mechanism via actuation of a latch release mechanism for permitting angular movement of the headrest from a normal use position to a dumped position. The headrest folding apparatus also includes a movement coordinating mechanism that is operative for causing movement of the headrest from its use position to its dumped position in response to movement of the seatback panel from an upright position to a forwardly folded position. Furthermore, the headrest folding apparatus is operative for coordinating actuation of a seatback latch mechanism in concert with the headrest latch mechanism. A latch release mechanism operably interconnects the headrest latch mechanism to the seatback latch mechanism. In operation, the headrest latch mechanism is automatically shifted from its locked mode to its released mode in response to the seatback latch mechanism being actuated for unlatching the seatback panel.

Abstract: La présente invention est un dispositif d'actionnement de verrou, destiné à servir dans une serrure de porte, et qui comprend une tige de pêne qui engage en sens vertical une cavité correspondante dans le bâti dormant. Le dispositif d'actionnement comporte une première et une deuxième partie d'un coffret, qui s'emboîtent pour délimiter une chambre intérieure, la première partie du coffret étant fixée au cadre de la porte. Une glissière à l'intérieur se déplace par un entraînement qui consiste en une came munie d'un doigt qui s'allonge de manière radiale pour engager une cavité dans la glissière. La came présente un cylindre axial engagé par une plaque de manoeuvre, à son tour sélectivement tournée par l'action du cylindre de clé dans la serrure de la porte au moment de la rotation du cylindre par une clé. La tige de pêne s'attache à la glissière à son extrémité inférieure. Le mouvement de rotation du cylindre de clé est transféré à la plaque de manoeuvre, et ensuite à la came, ce qui fait pivoter le doigt de came allongé radialement, et déplace la glissière sur un axe vertical, à l'intérieur de la chambre. La glissière déplace à son tour la tige de pêne dans un mouvement vertical similaire, engageant ou désengageant la cavité dans le bâti dormant, verrouillant ou déverrouillant ainsi la porte. La tige se trouve au-dessous de la glissière et de la came, ce qui permet à la largeur totale du dispositif d'actionnement et à l'assemblage de tige de pêne d'être de dimensions plutôt réduites, convenable à des cadres de porte peu larges. Le coffret à être encastré dans le cadre de porte est d'une conception qui permet son installation sur les portes ordinaires, sans nécessiter ni d'outils coûteux, ni les talents d'un serrurier professionnel.

Abstract: An improved version of a vibration isolation system using negative stiffness incorporates a payload (15) and payload platform (14) on just one 6 DOF isolator (12) in a unique and innovatively compact configuration. The isolator (12) includes a platform (14) supported on an assembly of independently acting flexure mechanisms which are connected in a serial fashion, tilt on top of horizontal on top of vertical, and in turn connected to a base (12). Proper arrangement of the mechanisms and the payload/platform center of mass (17) provides highly effective decouple isolator performance. In addition, an innovative flexure preloading method which significantly improves vertical isolation performance is incorporated. This method can be used with prior (unsymmetric) designs or combined with a set of shear flexures (66) in an innovative symmetric arrangement to provide more assurance of ideal decouple response to mutually perpendicular base excitation input. A geared mechanism (116) is also incorporated to facilitate manual adjustment of a main support spring (18) whenever payload weight is changed.

Abstract: An aircraft inertial webbing reel is mounted in a housing and has a ratchet wheel.  A dog is mounted for spring-biased movement into engagement with the ratchet wheel teeth to lock the reel.  A spring-biased blocking cam normally blocks movement of the dog.  An inertia mass (96) movable within a chamber (94) has opposed end mounting surfaces (112, 130) with conical fittings (114, 132) which define an axis.  A linkage (100) comprising a pair of interconnected levers (102, 120) each having a distal end (106, 124) having a conical fitting (108, 126).  The fittings each confine a ball (118, 136) to mount the mass (96) on the lever distal ends (106, 124).  A sliding and pivotal fitting interconnects the lever proximal ends (138, 146) and provides an overcenter mechanism normally biasing the lever distal ends (106, 124) toward each other and against the mounting surfaces (112, 130) to clamp the balls (118, 136) within the conical fittings (108, 114, 132, 126).  A predetermined acceleration of the aircraft (90) in any direction causes the mass (96) to shift the balls (118, 136) and move the lever distal ends (106, 124) away from each other.  This moves an output member (152) which shifts the blocking cam to unblock the dog which locks the ratchet wheel, reel and webbing.  The housing (92) is mounted with the mass axis oriented laterally of the aircraft (90) so that the linkage (100) provides the same output in response to movement of the mass (96) laterally of the aircraft (90) along the axis or in any direction forwardly and vertically of the aircraft (90) in a plane perpendicular to the axis.  In another embodiment, the levers are connected by a link (38).

Abstract: Reference information (15) for a biological slide (11) is obtained. The reference information (15) normalizes the measured object features (19).  Calibrated feature measurement (21), not based on absolute measurements, self-adjusts to match the situation of each slide (11), where each slide (11) is characterized by the reference information (15). The reference may be different from slide to slide because of the preparation variations. The calibrated features (21) will not carry the interslide variations. In addition, the reference information (15) provides a good indication of the slide condition such as dark stained, air dried, etc. which can be used as slide features (21) for the specimen classification. No alteration of the current practice of specimen preparation is required. The many slide context dependent features (21) improve the classification accuracy of the objects in a specimen (11).
Patent CA-2202511-A1 (CA)
Title: Targeted delivery via biodegradable polymers
Inventor: HERMAN STEPHEN JACK
IPC: A61P43/00
Filed: 1995-10-11
Abstract: Delivery of bioactive molecules such as nucleic acid molecules encoding a protein can be significantly enhanced by immobilization of the bioactive molecule in a polymeric material adjacent to the cells where delivery is desired, where the bioactive molecule is encapsulated in a vehicle such as liposomes which facilitates transfer of the bioactive molecules into the targeted tissue. Targeting of the bioactive molecules can also be achieved by selection of an encapsulating medium of an appropriate size whereby the medium serves to deliver the molecules to a particular target. For example, encapsulation of nucleic acid molecules or biologically active proteins within biodegradable, biocompatible polymeric microparticles which are appropriately sized to infiltrate, but remain trapped within, the capillary beds and alveoli of the lungs can be used for targeted delivery to these regions of the body following administration to a patient by infusion or injection.
