Abstract: Dans le cadre de l'augmentation constante des vitesses de transmission se fait ressentir le besoin d'appliquer des techniques de transmission qui permettent une exploitation optimale du moyen de transmission concerné. Dans la zone de raccordement d'abonné, on utilise, comme moyen de transmission, un câble. Les débits de transmission doivent être alors adaptés à la largeur de bande du câble, même pendant le fonctionnement. Les procédés de transmission mis en oeuvre dans l'état antérieur ne peuvent être adaptés à ces exigences qu'avec certaines réserves. L'invention permet de palier cet inconvénient par le fait que des signaux d'information (D) et des signaux de commande (SCM) sont transmis dans une structure à trames à des vitesses pouvant être réglées de façon variable, et par le fait que les signaux de commande (M) peuvent être utilisés pour l'adaptation de la vitesse de transmission au câble et aux besoins de l'abonné.

Abstract: A gasket for sealing the supporting edge of toilet bowls or bases against the floor, specifically for sealing the inside of tire bowls and allowing proper support with respect to irregularities in said edge or in the floor. Toilets are installed on bathroom floors directly on the surface or by inserting a packing that provides for proper support, but this does not achieve sealing of the inner body of the toilet to prevent the entry of sewage or floor-washing water nor the escape of waste odors. The proposed model entails a sealing gasket that allows for both correcting irregularities in the supporting edge of the bowl and in the floor, comprised of an annular member having a shape drat corresponds to toilet models currently on the market and provided with a flat seat for supporting tile bowl with an outer perimetrical flange for support on the outer part of the bowl and an inner perimetrical rib that is slightly hinged for support on the inner surface of the bowl in order to provide a seal. Proposed for these gaskets is the incorporation of a tubular section that also seals the connection between the toilet drain and the sewer line. Said tubular section is integrally connected to the annular section at one end, which concentrically surrounds said connection and which has an upper wall with a sealing lip for the drain joint with the sewer line and a means of scaling the connection with the floor to be arranged concentrically to the connection. This sealing means comprises a boot with a vent-type socket, which is to be supported on the floor or, in one variant of the embodiment, a series of concentric fins that are supported on the floor in order to prevent the escape of liquids or gases.

Inventor: DELORME JUDITH C
IPC: A61Q19/08
Filed: 2001-10-16
Abstract: I have personally experienced evidence that the elastic protein molecules in plants (latex) are similar or identical to the elastic protein molecules in human and animal tissue (elastin). It has been scientifically proven that the human body ceases to manufacture elastin soon after puberty, the gene is "turned off". Therefore, the introduction of the plant protein (latex) may significantly or completely reduce the physiological breakdown characteristic of the aging process. This would positively affect the wrinkling and sagging of our skin, but much more importantly the function of our bodies.      Elastin is found in the walls of our arteries (28-32%), heart tissues, lungs (3-7%), elastic ligaments (50%), tendons (4%), stomach, intestines, skin (2-3%), elastic fibro-cartilage, and others.      When a gene for elastin is missing, "Williams Syndrome" causes premature aging in children. Individuals who have inherited SVAS (supravalvular arterial stenosis) have a mutation of the gene for elastin in one of their chromosomes; therefore for every molecule of normal elastin they produce, they also produce one of abnormal elastin thereby giving their "hybrid elastin" an abnormal structure which leads to a defective elastin protein.      My extensive searches have shown that all research to date has been genetically based, and that all products manufactured to date have been based on the extraction of elastin from animal tissue. I find no indication that anyone has ever considered using the plant-derived elastic molecule to replace the elastic molecule existent in humans and animals.

Abstract: A call is routed from a user location to a local call termination point by mapping a dialed toll free number to a POTS-routable number within a local rate calling area (LRCA) that includes the user location. Enhanced services (for example, protocol conversion, etc.) may take place at the local call termination point; and, subsequently, the call may be routed from the local call termination point to a remote call termination point by mapping the POT S- routable number to another number (e.g., a long distance number) associated with a long distance call termination point. The dialed toll free number is mapped to a POTS-routable number by determining an originating NPA-NXX for t he user location, matching a routing NPA-NXX for the local call termination poi nt associated therewith, and selecting a line number for the local call termination point according to routing NPA-NXX and the dialed toll free number. The routing NPA-NXX is selected from a first table and the line numb er is selected from a second table. These tables may be stored as part of an SMS/800 service management system database within a telephony network over which the scheme is deployed.
