Embodiments of the invention relate generally to electrospun fibers and, more particularly, to the controlled release of an active pharmaceutical ingredient (API) from electrospun fiber scaffolds (EFSs).
摘要:
A heating device for heating a yarn, in particular in a texturing machine. The heating device comprises a thin-walled heating tube, which can be evenly heated on its circumference by a heating jacket. Fitted within the peripheral wall of the heating tube is an insert, which forms a yarn channel extending between a yarn inlet and a yarn outlet for guiding the yarn. The insert is formed by a special section rail that is open along one long side, and fitted with its opposite long side to the wall of the heating tube. As a result, the yarn channel is formed between the open long side of the special section rail and the wall of the heating tube, so that it is possible to supply heat to the yarn channel directly via the wall of the heating tube.
摘要:
A heating device for heating at least one advancing yarn in a texturing machine, wherein the body of the heating device defines an elongate heating channel. The heating channel accommodates an exchangeable support which mounts a plurality of yarn guides which are arranged inside the heating channel for forming a plurality of adjacent yarn guide tracks for guiding a plurality of yarns in such a manner that the yarns advance in a yarn advancing plane extending at a predetermined distance from the bottom wall of the heating channel.
摘要:
A cooling apparatus and method for cooling an advancing yarn, which includes an elongate cooling rail along which the advancing yarn is guided. At each end of the cooling rail, the yarn and the cooling rail are reciprocated relative to each other in a direction transverse to the direction of the advancing yarn, so that the yarn sweeps over the cooling surface of the cooling rail, thus facilitating the removal of a possibly developing condensate.

A MACHINE TOOL ARANGEMENT HAVING A DEVICE FOR CONTROLLING THE CHUCK THEREOF, COMPRISING A BASE, A HEADSTOCK MOUNTED THEREON, AND A SLEEVE AXIALLY SLIDEABLE WITHIN THE HEADSTOCK, THE CHUCK BEING ROTATABLE WITHIN THE SLEEVE. THE CHUCK IS ARRANGED TO BE ROTATABLE BY A SHAFT DISPOSED PARALLEL AND NON-COAXIALLY THERETO BY A TRAIN OF GEAR WHEELS DISPLACEABLE TOGETHER WITH THE SLEEVE, RELATIVE TO THE SHAFT. THE SLEEVE IS ARRANGED TO BE SHIFTED AXIALLY BY MEANS OF A MECHANISM ARRANGED PARALLEL AND NON-COAXIALLY WITH THE SHAFT TO APPLY ROTATIONAL FORCE TO THE CHUCK IN A MANNER SUCH THAT THE TORSIONAL DEFORMATION THEREOF REMAINS CONSTANT THROUGHOUT THE ENTIRE CHUCK STROKE.
