  • Patent number: 5976235
    Abstract: Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, a cellulosic ether, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the cellulosic ether to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation.

  • Patent number: 5975238
    Abstract: The invention concerns a plate resonator for absorbing sound and including a thin front plate with high elasticity and low internal friction, e.g., made of metal; a back plate which likewise has high elasticity but which has high internal friction; an all-over solid connection between the front and back plates in the form of a bonded connection (e.g. double-sided adhesive tape); and a border which is closed all around by the back plate but does not prevent sound entering the back plate from the side.

  • Patent number: 5977262
    Abstract: The reactions of cyclic carbonates, especially 1,3-dioxolan-2-ones, with amines, especially primary amines, are catalyzed by the presence of a base whose conjugate acid has a pKa of about 11 or more. The products are hydroxy urethanes, and the process can be used to form crosslinked polymers which contain urethane groups. Such crosslinked polymers are useful in coatings.

  • Patent number: 5971217
    Abstract: A liquid storage and dispensing device includes a bottle and a fluid flow control device which is mounted to the neck of the bottle. The bottle includes a planar surface upon which the bottle may rest in an inclined orientation, with the neck of the bottle pointed down. The planar surface is formed at an angle with respect to the rest of the bottle geometry so that the center of gravity of the bottle, when full of liquid and in the inclined orientation, is above the planar surface. Thus, the full bottle is able to be safely stored in the inclined orientation with any level of liquid contained in the bottle, without concern that the bottle will topple over, and the liquid contents may be dispensed through the fluid flow control device.

  • Patent number: 5972199
    Abstract: A sensor for the detection and measurement of an analyte in a biofluid. The sensor includes two enzymes. One type of sensor measures the concentration of hydrogen peroxide using a thermostable peroxidase enzyme that is immobilized in a redox hydrogel to form a sensing layer on a working electrode. This sensor also includes a hydrogen peroxide-generating second enzyme which is insulated from the redox hydrogel and electrode. This second enzyme generates hydrogen peroxide in response to the presence of an analyte or analyte-generated compound. The second enzyme may be insulated from the electrode by placement of an electrically insulating layer between the sensing layer and the second enzyme layer.

  • Patent number: 5971731
    Abstract: The present invention relates to a novel arrangement for attaching, by screw threads, one device to another wherein the one device has a greater thermal rate of expansion than the other and the devices are assembled at a temperature which is lower than that at which the two devices are regularly subjected. In particular, the novel arrangement maintains the security of the attachment where the differing thermal rates of expansion would normally cause the screw thread attachment to become loose.

  • Patent number: 5971998
    Abstract: A support device for controlling breast thickness during stereotactic guided needle biopsy is provided. The support device includes a compressible support having an inner surface which extends adjacent to a substantial portion of a peripheral surface of a patient's breast when the breast and the support are disposed between the fixed and pressure plates of an apparatus for performing stereotactic guided needle biopsy. The compressible support restricts the inferior and lateral excursion of the breast as the plates are moved toward one another and the patient's breast and the compressible support are pressed between the plates. A method for controlling breast thickness during stereotactic guided needle biopsy is also provided.
