Abstract: A medical instrument, such as a cautery device, wherein bleeding is stopped or prevented by clamping the bleeding site with a dedicated forceps and using a highly localized heat source such as a fiber-coupled laser. The laser energy quickly and locally heats up the tip of the forceps cautery device. The tip of the forceps device has minimum thermal mass and is thermally insulated from the body of the forceps. In this present invention, there is no electrical current flowing through or into the tip of the instrument, and can therefore be safely used in any part of the body including around the heart or the brain. When combined with a small semiconductor laser, the device is battery operated, self-contained and hand-held, and can therefore be used in any environment including outdoors.

Preferred fibers have non-round cross-sections, especially multi-grooved and scalloped-oval cross-sections that provide fabrics having outstanding comfort qualities of moisture-management, dryness and comfort, as well as minimal pilling.

Abstract: The present invention refers to a process for stabilizing LAA in an aqueous medium, which includes the step of contacting the LAA with at least one compound capable of forming hydrogen bridges with the LAA. In another aspect, the invention relates to a stable aqueous LAA composition which includes, in addition to said ascorbic acid, at least one compound which is linked to the LAA by hydrogen bridges, and to a process for preparing it. The present invention further relates to an emulsion including, in its aqueous phase, at least one compound linked to levogyre ascorbic acid (LAA) by hydrogen bridges. Further according to the present invention a vitamin product is provided, in which a stable LAA composition as described above is contained in organic envelopes which enable a gradual and prolonged release of the LAA into the organism. The vitamin product may further include a compound capable of stimulating the metabolism of the fibroblasts.

Abstract: A sheath-core polyester fiber where the sheath includes an antimicrobial agent and the sheath comprises less than thirty percent of the total cross-sectional area of the fiber. The antimicrobial agent is selected such that the relative viscosity of the fiber lies above a defined spinnability limit, so that spinning is possible. With no loss in antimicrobial efficacy, the fiber of the present invention may be slickened with a siliconized finish in order to reduce fiber friction, thus giving the fiber a silky feel.

Abstract: The present invention relates generally to multi-layer film compositions which can be thermoformed and heat set into clear, transparent articles, having excellent barrier properties. The compositions comprise at least one barrier layer and at least one polyester layer, whereby the polyester layer will quickly crystallize and heat set into an optically clear layer material.

Abstract: Copolymers of sulfur dioxide and/or carbon monoxide and olefins, especially ethylene, can be made by contacting these monomers with a combination of selected strong Lewis acid and a selected metal or a compound of a selected metal. The resulting polymers, which are often alternating copolymers, are useful as molding resins.

Abstract: An ink jet ink composition is provided which contains an aqueous vehicle; a colorant; and a polymeric dispersant comprising 2 to 50% by weight of monomers selected from .beta.-diketone containing monomers and ureido monomers, as well as a combination of such ink with a media having basic groups such as primary or secondary amines and divalent cations.

Abstract: Polarization combiners and dividers are used in combination with WDM multiplexers and demultiplexers to create fiberoptic network systems with increased bandwidth and number of network users. Besides wavelength, the state of polarization of the optical signals creates different communication channels for the network system. The present invention is adaptable to many different fiberoptic network arrangements.

Abstract: The present invention relates to industrial fibers and products made therefrom and more specifically to industrial polyester fibers and products made therefrom. The fibers comprise a synthetic melt spun polymer having a relative viscosity about 24 to about 42, a denier of about 4 to about 8, a tenacity of about 6.5 grams/denier to about 9.2 grams/denier, and an elongated diamond shaped cross section normal to a longitudinal axis of the filament, the cross section having an aspect ratio of about 2 to about 6.

Abstract: An ophthalmic instrument and ophthalmic method for preventing epithelium cells from being deposited at the stroma interface during LASIK. The ophthalmic instrument has a base having a flat abutment face, two mutually concentric annular blades upstanding from the abutment face, and a cross-hair for sighting the position of the annular blades. The annular blades have a height of about 50 microns with respect to the abutment face, an inner annular blade thereof is from about 9 mm. to about 9.5 mm. in diameter, and an outer annular blade thereof is about 10.5 mm. in diameter. The ophthalmic method is performed prior to LASIK. The ophthalmic instrument is aligned over the cornea via the cross-hairs and then pressed upon the eye of a LASIK patient so that the annular blades cut into the cornea until the abutment face abuts the cornea and prevents further penetration. The depth of cut of the annular blades is such as to completely cut through the epithelium.

Abstract: A method for detecting the presence of a nucleic acid analyte in a test sample is provided in which a test sample is contacted with a test strip of a chromatographic bibulous porous material which is capable of moving the test sample laterally along the test strip by capillary migration to ultimate capture by a moiety in a specific capture zone.
