Inventor: JENSEN ROBERT M
IPC: E03D1/14
Filed: 1996-04-19
Abstract: A toilet flushing mechanism includes a dual flush device for effecting both a short flush cycle and a long flush cycle in a toilet tank including a flush valve actuated by an actuation arm. A cam operable by a handle is rotatably supported adjacent the actuation arm.  When rotated in a first direction, the cam acts to press against and pivot the actuation arm to effect the long flush. When rotated in the second direction, the cam acts to press against and pivot said actuation arm to effect the short flush.  A lever is pivotably supported with respect to the actuation arm and pivots between a first position out of blocking contact with the actuation arm and a second position where the lever blocks return of the actuation arm for a predetermined period of time when the cam is rotated in the second direction.  A float is coupled to the lever for determining the predetermined period of time.  The float acts to pivot the lever into the second position when the cam is rotated in the second direction.   Where the toilet tank includes an overflow tube and a water control there is a trapway reseal device for the toilet tank.  The trapway reseal device includes a float slidably supported along the  overflow tube  to move with the changing level of water in the tank as the tank is flushed and refilled.  A reseal hose receives water from the water control and includes a free_ end coupled to the float.   The reseal hose selectively directs water into at least one of the tank and the overflow  tube  dependent  upon  the  position  of  the  float  as determined by the level of water in the tank.

Title: Polychrome passive display apparatus
Inventor: DUCHESNEAU RICHARD
IPC: G09F11/12
Filed: 1996-06-21
Abstract: The passive display apparatus comprises first  and second spaced apart  sprocket assemblies rotatable   about   respective   first   and   second transversal axes.  An endless chain system is mounted on the first and second sprocket assemblies and is composed of mutually interconnected links articulated about third axes parallel to the first and second axes.    Each  link  comprises  a  tongue  extending outwardly from the endless chain system for supporting an endless array of closely adjacent cubes.  The cubes are mounted rotatable on the tongues about fourth axes parallel to the third axes but offset outwardly with respect  to these third axes.   Each cube has  two opposite   square   first   faces   centered   on   a corresponding one of the fourth axes and four second square faces of different colors.   Since the fourth axes are offset outwardly with respect to the third axes, the closely adjacent cubes of the array space apart from each other as they move around the sprocket assemblies to enable rotation of these cubes about their respective fourth axes in view of exposing on a display surface of this array those second faces of the cubes required to construct a desired image.

Title: Insulating rigid polyurethane foams
Inventor: WHITE WALTER R III
IPC: C08G18/48
Filed: 1996-08-05
Abstract: There is now provided a polyisocyanate based rigid closed cell foam made by reacting an organic isocyanate with a polyol composition in the presence of a blowing agent, where the polyol composition contains at least: a) an aromatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; b) an aliphatic amine initiated polyoxyalkylene polyether polyol having an hydroxyl number of 200 meq polyol/g KOH or more; and the blowing agent is at least cyclopentane in an amount of 7 weight percent or more based on the weight of the polyol composition; and further, the cyclopentane blowing agent is soluble in the polyol composition, and the amount of the aliphatic amine initiated polyoxyalkylene polyether polyol is 10 weight percent or less based on the weight of the polyol composition. The polyol composition is adapted to solubilize cyclopentane in the polyol composition without sacrificing, and advantageously improving, the thermal insulation and dimensional stability of the resulting polyurethane foam. It was surprising to discover that less than 10 weight percent of the aliphatic amine initiated polyol was need to accomplish these objectives, and it was further surprising to discover that the aromatic amine initiated polyether polyol improved the thermal insulation of the foam.

Abstract: A waterproof film (11) for covering fitting portions is closely formed on surfaces of a cap (6), barrel (3) and a cylinder body (2) to serve as a sealing construction for a syringe. The film is made of a synthetic resin having a higher fusing point than a temperature of steam which passes at the time of after-sterilization. A substantially wave-shaped inclined lip (24) is continuously formed on and projected from an outer periphery of a short-column shaped elastic body (22) to serve as slide valves for a syringe. An annular lip (23) is formed on an end of the body. A notch (34) for introduction of chemicals is formed on the inclined lip. The inclined lip is constructed such that substantially diverging lips are formed in pairs or in multi-stage or in axial ridges or intersecting one another in a corrugated manner. These slide valves are inserted and mounted without inclination to eliminate accumulation of air inside. In the syringe, an enlarged diameter portion (87) having a larger diameter than that of a cylinder is formed integrally on a tip end side of the cylinder such that it has a larger inner diameter than outer diameters of the slide valves to permit a chemical to be discharged through a gap around the outer periphery. A support projection (94) for the slide valves is formed at a bottom wall of the enlarged diameter portion to provide a bottom gap. A  slide valve (90) comprises a body (101) having a smaller diameter than an inner diameter of the enlarged diameter portion, and a support member (102) having a lower elastic modulus than that of the body and a plurality of circumferentially equidistantly distributed support projections which project diametrically from inside of the body and contact with an inner surface of the enlarged diameter portion. The cylinder is of unitary-type, so that passing steam, bacteria and the like are prevented from entering the syringe.

Abstract: L'invention concerne un appareil permettant d'enlever du tissu d'un oeil, ainsi qu'un procédé de commande d'un tel appareil, ledit appareil effectuant divers types de corrections au moyen d'un faisceau qui est relativement grand, mais qui oscille ou tremblote, afin d'empêcher la formation de nervures de renforcement lors du processus d'enlèvement des tissus. En outre, avec un tel appareil, il est possible de procéder à divers types de corrections, par exemple la correction de l'hypermétropie et de l'astigmatisme, au moyen d'un grand faisceau avec lequel on balaye la zone à traiter, en procédant par des décharges se chevauchant. En outre, pour enlever l'épithélium se trouvant dans la zone à traiter, on utilise pour teinter celui-ci une teinture fluorescente à infrarouge, puis l'on observe les motifs fluorescents émis par la zone de l'épithélium à enlever. Lorsqu'une certaine zone n'est plus fluorescente après les décharges du faisceau laser, l'on procède à de plus petites décharges du faisceau laser, afin d'enlever, de façon sélective, l'épithélium des régions restantes. On observe, de nouveau, les motifs fluorescents et l'on recommence l'opération jusqu'à ce qu'il ne reste plus d'épithélium. A ce stade, l'épithélium est alors complètement enlevé et une carte est créée qui représente l'épaisseur initiale de l'épithélium à chaque point de la zone où celui-ci a été enlevé. Lorsqu'on utilise deux motifs d'ablation qui sont destinés à corriger l'astigmatisme et se recoupent selon un certain angle, on crée une lentille susceptible de corriger la myopie, l'hypermétropie et l'astigmatisme. En outre, en utilisant pour les décharges se chevauchant une dimension relativement grande de points fixes, on diminue l'échauffement thermique ainsi que le nombre de passages on obtient des motifs de traitement sans nervures et le matériel est simplifié.
