  • Patent number: 6095604
    Abstract: A vehicle seat is provided which has a cushion portion for alternately supporting a seated occupant or a bottom portion of a child seat. The vehicle seat also has a seatback portion with a rearward facing surface and a forward facing surface for alternately supporting a back region of a vehicle seat occupant or a seatback of a child seat. A connector receptacle is recess mounted into the rearwardly facing surface of the vehicle seatback to permit engagement with a connector extending from the seatback portion of a child's seatback. The connector receptacle has a bar onto which a hook of the connector attaches.

  • Patent number: 5094740
    Abstract: Separation methodology is disclosed which allows for the separation of mixtures of carbohydrates into highly resolved detectable bands of carbohydrates. The method involves first reacting a mixture of carbohydrates with charge generating moieties which are capable of fluorescing such as 1-amino-4-naphthalene sulfonic acid (ANSA) to form carbohydrate conjugates. The conjugates are subjected to a first-dimensional gel electrophoresis in a first direction to provide separate bands of carbohydrates in the gel. A band in the gel is removed and subjected to second-dimensional electrophoresis in a second direction which is substantially perpendicular to the first direction. More specific bands of more highly resolved carbohydrates are then formed in the second-dimensional gel. The more specific bands within the second-dimensional gel are then electro-blotted onto a substrate surface and can be viewed in extremely small amounts due to the fluorescent capability of the ANSA when viewed under ultraviolet light.

  • Patent number: 5087337
    Abstract: A method of separating mixtures of saccharides into distinct detectable groups is disclosed. In accordance with the method a tri-functional conjugate must first be provided. The tri-functional conjugate is obtained by reacting a mixture of saccharides with moieties (a) capable of providing a charge upon ionization; (b) capable of fluorescing under ultraviolet light; and (c) having a light-activatable azido group thereon. The different functional moieties may all be present on the same moiety and connected directly to the saccharide or may be connected to each other wherein only one of the moieties is connected directly to the saccharide. The tri-functional conjugates are subjected to electrophoretic separation to obtain separate groups of conjugates in the gel. The groups of conjugates are transferred from the gel to the surface of a membrane which is exposed to light for a sufficient time and light frequency to activate the azido-group.

  • Patent number: 4966845
    Abstract: The nonnutritive sweetener L-altrose is obtained from extracellular polysaccharides elaborated by certain strains of the bacterium Butyrivibrio fibrisolvens when grown on a carbohydrate-containing nutrient medium. L-altrose has not previously been found in nature.
