Abstract: Silk is purified to eliminate immunogenic components (particularly sericin) and is used to form fabric that is used to form tissue-supporting prosthetic devices for implantation. The fabrics can carry functional groups, drugs, and other biological reagents. Applications include hernia repair, tissue wall reconstruction, and organ support, such as bladder slings. The silk fibers are arranged in parallel and, optionally, intertwined (e.g., twisted) to form a construct; sericin may be extracted at any point during the formation of the fabric, leaving a construct of silk fibroin fibers having excellent tensile strength and other mechanical properties.

Abstract: The invention relates to an apparatus for treating a multifilament thread in a melt-spinning process, wherein a treatment channel is formed between a housing plate and an impact plate. The housing plate has a nozzle bore which opens into the treatment channel and is connected to a compressed-air connection. Together with the housing plate, the impact plate forms an inlet opening and an outlet opening at both ends of the treatment channel. In order to check the swirling effects which are produced on the thread by the eddying within the treatment channel, according to the invention the impact plate has a thread guiding element in the part piece of the treatment channel between the nozzle bore and the inlet opening, which thread guiding element is configured so as to protrude into the treatment channel in order to deflect the thread.

Abstract: A yarn system, apparatus, and methods of reducing production loss or increasing production speed in a continuous yarn production process are provided. A yarn conveyor receives a bundle of yarn, an oven heats the yarn, and a yarn cooler cools the yarn exiting the oven to heat set the yarn. The conveyor carries the yarn through the oven and cooler. A counterband extends through the oven substantially parallel to and above the conveyor to abuttingly contact the yarn against the conveyor. The counterband is formed by hydrophobic fibers woven in a mesh pattern that form apertures to enhance flow of a heated fluid between the fibers. A cooling efficiency of the cooler is increased responsive to the hydrophobic fibers allowing the cooler to cool the yarn without moisture from the heated fluid being absorbed by the counterband.

Abstract: The invention comprises a fixture and method for holding optical waveguid such as fiber optic cable, in a relatively stable fashion for processing. The fixture includes a first frame and a second frame, releasably securable to the first frame to form a unitary structure. Chambers disposed in at least one of the frames are adapted for removably receiving optical fiber cable when the first and second frames are released from one another and for securely retaining with molding material optical fiber cables when the first and second frames form the unitary structure. A process area is defined in the unitary structure such that segments of optical fiber cables secured therein are accessible in the process area for processing. An optional coating fixture is securable to said unitary structure for forming with a molding material a protective coating about the cable segments in the processing area.

Abstract: In the case of a paraffin waxing device for a travelling yarn, a rotating paraffin body is weighted in axial direction against a stopping face. The stopping face lies against the front surface of the paraffin body, over which the travelling yarn is guided. During the waxing process, undesired rubbing off of paraffin particles can soil the feed material or the machine elements. According to the invention, the stopping face is rolled on the rotating front surface. The rubbing-off of paraffin particles, in particular in the area of the stopping face, is hereby avoided.

Abstract: A method and apparatus for separating monofilaments, such as glass or carbon monofilaments, forming a strand, is achieved by feeding the strand in a curved path over and in forced contact with a plurality of rods, each being subjected to vibrations. The vibrations, applied transverse to the axis of the strand, provide intermittent localized contact between the filaments and the rod surface, hence preventing high tensile and shear forces which cause breakage of the delicate filaments. In one embodiment, the rods comprise a plurality of resonators dimensioned to be resonant along their longitudinal axis for a predetermined frequency of vibration. The resonators are energized with vibrations from a single resonator dimensioned to operate as a half wavelength resonator. The resonators are provided with a wear resistant, smooth surface coating at the area of contact with the filaments.
