Abstract: An artificial tube for a nerve is disclosed that has a controlled rate of decomposition in the body such that the tube remains in the body until the nerve regenerates, which induces axons regenerated from severed nerve stumps to extend in the proper direction without pressing on the regenerated nerve following nerve regeneration and causes rapid restoration of blood flow by promoting infiltration of blood capillaries from the body to promote regeneration of the nerve, and which comprises a tube (10) or (20) having a coating layer (13) or (23) that is composed of gelatin or collagen on at least the outer surface of tube (11) or (21) that is composed of a material that is biodegradable and absorbable in vivo, wherein a pre-thermal dehydration crosslinking treated collagen fiber bundle (referring to a bundle fibers (31) composed of collagen) is inserted in its lumen along the axis of the tube (10) or (20), and wherein the fibers composed of collagen are coated with laminin.
Abstract: A woven fabric, such as a base fabric for a press felt, which is designed for a papermaking machine or the like has along each one of two end edges a plurality of seam loops to be included in a loop seam to form an endless woven fabric. The fabric is characterized in that there is provided, at least at one of the end edges, at least one string of material, preferably in the form of one or more extra yarn threads, extended substantially parallel to the above-mentioned one end edge adjacent the regular thread system of the fabric. The extra yarn thread or threads are woven to only such portions of the seam loops as are facing a first side of the fabric, preferably the paper side thereof. In this manner, there is formed in the seam zone a type of extension of the regular thread system of the fabric, whereby the loop seam is conformed to the rest of the fabric to avoid markings in a paper web at the loop seam.

Abstract: An item of swimming wear (10) arranged to be worn closely to the body of a user to provide or enhance buoyancy, which item (10) comprises a piece of flexible closed-cell foam material (12) combined with a piece of textile or plastics material (11).
Abstract: In the combination of a carriage for the preparation and storage of fabric to be changed on a loom, a loom for receiving the fabric to be changed, and an insertion vehicle for changing the fabric at the loom, improvements in the method of fabric change as well as the associated carriage and insertion vehicle are set forth. The method allows the carriage for the preparation and storage of fabric to be changed to have the working distance between the warp stop motion and the loom to be adjusted dependent upon shed size, density of fabric and warp material. The carriage for the preparation and storage of fabric includes a warp clamp and adjustment for spacing the warp stop motion with respect to the loom harness and heald frames. The insertion vehicle includes a centering mechanism for placing the loom harness and heald frames to the loom.
Abstract: A papermakers fabric having a system of flat monofilament yarns which are woven with relatively long floats on at least one side of the fabric. In the preferred embodiment, the flat yarns are oriented in the machine direction of the papermakers fabric and are interwoven with at least a top layer of round cross machine direction yarns such that in each repeat, the flat yarns float over more top layer cross machine direction yarns than the number of top layer yarns which the flat yarns weave under. In the preferred embodiment, pairs of vertically stacked flat monofilament yarns are woven in the machine direction such that the upper flat yarns define relatively long floats on the top surface of the fabric and the lower flat yarns define floats on the bottom surface of the fabric.
Abstract: Methods for weaving three-dimensional fabric structures which have a desired cross-sectional shape and devices for such weaving in each of two mutually perpendicular directions allow sheds to be formed in planar warps.

Abstract: A yarn storage and feed device with a main body, a take-up element on which the yarn is wound, a storage surface for yarn storage, a threading device with a compressed-air feeder system and a device for activating direction-jet nozzles. At least one direction-jet nozzle is located between the point of entry of the yarn into the storage and feed device and the feed-out point from the yarn-winding element; this nozzle can be activated independently of the nozzles fitted downstream of the feed-out point so that in the event of a partial failure, where stored yarn remains on the storage surface, the yarn end can be blown below the feed-out point.
Abstract: An insertion device for a series-shed loom having a rotor including combs (2) and shedding members for guiding the warp threads (3) over a predetermined angular region for shedding. The insertion device has a laying bar (10) with recesses (24) to guide the warp thread (3). It is moved to and fro parallel to the rotor by a drive mechanism for inserting the warp threads (3) into the shedding members on the rotor. Each laying bar (10) is associated with a guide bar (25) for deflecting the warp thread (3) for aligning it with the recess (24) in the laying bar (10). As a result the laying bar (10) is advantageously relieved of most of the warp thread tension and only directs the warp just parallel to the rotor. The laying bar (10) may consequently have a low mass.
