Abstract: A substantially-isolated/controlled, limited-volume, gas-filled space (e.g., 113b) is formed over at least one free (open) surface of flowing molten glass in a manufacturing line used to produce glass sheets (137), e.g., a manufacturing line employing the fusion process to produce glass sheets suitable for use as substrates for liquid crystal displays. At least a portion of the space comprises a platinum-group metal, e.g., a platinum-rhodium alloy, which can serve as a source of platinum-group condensate defects. The use of the substantially-isolated/controlled, limited-volume, gas-filled space substantially reduces the level of such platinum-group condensate defects in the glass sheets, e.g., by more than 50%.

Abstract: This invention relates to a device for performing plasma chemical vapor deposition (PCVD) for producing coated glass tubes for the drawing of optical fibers. This invention further relates to a device that uses a microwave applicator, and the applicator itself with a profile that allows for a uniform coating across a greater length of the glass tube.

Abstract: A method of protecting a silica-containing article used in the manufacture of an optical fiber includes the step of applying to the silica-containing article a protective layer that facilitates removal of particulates that deposit on the protective layer and that ablates during or can be removed before subsequent processing of the silica-containing article. An intermediate product used in the manufacture of an optical fiber and protected against break-inducing particulates includes a silica-containing article, and a protective layer that facilitates removal of particulates-that have deposited on the protective layer and that can be ablated during or removed before subsequent processing of the intermediate product.

Abstract: Absorbent articles such as panty liners, thin full-sized sanitary napkins and the like having a garment facing side and a body facing side are provided which may be stored in a folded configuration prior to use. Means of attachment and means of release, most preferably silicone, are created on the garment facing side of the article. The patterns in which the attachment and release means are chosen such that when the article is folded, the adhesive means contact the release means, eliminating the need for release paper, but allowing the article to be unfolded and used. Other embodiments using barrier films affixed to the garment facing side of the article are also disclosed. Methods of making and packaging the articles disclosed are also provided.

Abstract: An absorbent structure for absorbing body fluid is provided having means to direct body fluid along the longitudinal axis of the product and to substantially limit side failure. Two or more longitudinal chambers of absorbent material are provided which are separated by fluid repellent walls. These walls act to guide flow generally along the longitudinal axis of the product.

Abstract: An apertured film, suitable for use as a sanitary napkin cover which passes body fluids, is provided. The film comprises a first layer of a first polymeric material and a second layer of a second polymeric material. Both layers are apertured for the transmission of body fluids therethrough. The first polymeric material exhibits a melting point temperature which is greater than the melting point temperature exhibited by the second polymeric material. The apertured film may be thermally bonded by heating the film to a temperature in excess of the melting point temperature of the second layer material and below the melting point temperature of the first layer material. The unmelted first layer will thereby maintain the integrity of the apertured film when the second layer is in its thermally softened condition.

Abstract: This invention provides a sanitary napkin of the type emplacement in the inner crotch portion of an undergarment. The napkin comprises a central absorbent element having flaps extending from each of its longitudinal edges. The flaps extend to a sufficient length to allow the flaps to overlie the outer crotch portion of an undergarment with the flaps being sufficiently drapable so as to allow each to fold about the crotch portion at any of an infinite number of lines lying essentially parallel to the junction line between the absorbent element and each flap. Accordingly, when the sanitary napkin is applied to crotch portions of varying width, the napkin will conform to the dimensions of the crotch and be emplaced without wrinkling.
