Abstract: A bite block for use in a mouth of a patient to hold the mouth in a spaced-apart position that includes a condensed fiber block having a predetermined length suitable for being inserted into the mouth of the patient and positioned between upper and lower molars and a wrapper yarn repeatedly wrapped around the block along its length. An adhesive strand in the wrapper yarn is positioned on an outer surface of the fiber to maintain the block in its condensed state.

Abstract: A process for encapsulating a radioactive object to render the object suitable for shipment and/or storage, and including the steps of preparing a plastic material, causing the plastic material to react with a foaming agent, generating a foaming plastic, encapsulating the radioactive object in the foaming plastic, and allowing the foaming plastic to solidify around the radioactive object to form an impervious coating.

Abstract: A method of compressing a cotton strand including the steps of providing an uncompressed strand having an original volume, providing a container adapted to collapse about the strand, feeding the strand into the container, compressing the container to remove a first quantity of air, applying a vacuum to the container to remove a second quantity of air, and sealing the container, wherein the strand is compressed by at least about 25% from its original volume.

Abstract: A method of packaging textile coil includes the steps of providing a strand of loosely assembled textile fibers, feeding the strand into a collapsible container, compressing the container so as to cause the container to collapse and compress the strand to a preselected degree, and sealing the container to maintain the strand in a compressed state.

Abstract: A closed cell, HFC-245fa blown rigid polyurethane foam system designed for lifting concrete composite slabs back to their original position in either wet or dry site conditions. The blown rigid polyurethane foam includes an isocyanate (A) component and a polyol (B) component. The isocyanate and polyol are fed to a metering system and separately pumped to a two-component mix head. An exit nozzle of the mix head is extended into an injection hole formed in a slab and injected into a void beneath the slab to be lifted causing a reaction. The reaction creates a closed-cell foam that lifts and supports the concrete slab.

Abstract: An opened, wet processed, intermediate natural fiber product suitable for formation into end use fiber products, which includes an effective amount of an antimicrobial agent applied to the fibers during wet processing.

Abstract: This invention relates to an apparatus for dispensing cotton rolls. More particularly, this invention relates to an apparatus which may be supported on a work table, credenza, sideboard or the like in use in an operating room such as a dental operatory for readily supplying users such as dentists, surgeons, and assistants with absorbtive cotton rolls. The dispenser has a base which defines a delivery chute portion having horizontally spaced apart, upwardly directed surfaces, to which rolls are dispensed from a reservoir formed in part by a pair of planar lower wall portions, each lying on a plane parallel to said axis of rotation and diverging upwardly from a juncture line below the location of the axis of rotation of a dispensing wheel, and which direct rolls to the dispensing wheel which is mounted for rotation about a generally horizontal axis spaced above the delivery chute.
