    • Leaks from a hollow fiber membrane module comprising a housing having one or more hollow fiber bundles positioned therein with at least one end of each bundle being sealed by a cementing layer includes the step of applying a pressurized gas to the external surfaces of the hollow fibers. The gas which is used must have a refractive index different from the refractive index of the ambient atmosphere. The atmospheric volume adjacent the sealed end of the module is optically monitored for refraction patterns caused by gas leaking through the sealed end into the volume. The optical system includes a light source and components for directing light from the source along an optical path including the monitored volume. Light which is passed through the monitored volume is directed to an optical display where the refraction patterns of the leaking gas will be visible. The method and apparatus permit leaks to be located without the use of liquids.

    • A method and apparatus for continuously withdrawing an elongated product such as from a melt a fine wire is based on the rotating liquid medium spinning method. A layer of cooling liquid (14) is centrifugally formed on the inner peripheral surface of a rotational drum (13). Disposed inside the rotational drum (13) is a winding reel (19) having a rotating winding peripheral surface (18). A holder element (20) adapted to be magnetically attracted to the winding peripheral surface (18) is initially placed on the inner peripheral surface of the rotational drum (13). A molten material injected into the drum by a nozzle (16) is quenched for solidification in the cooling liquid (14) to form the product. Initially, the leading end emerging from the nozzle rides over the holder element (20) which then carries the leading end onto the winding peripheral surface (18) and holds it thereon by magnetic attraction. The product (17) is then wound on the winding peripheral surface (18) with its portion fixed by the holder element (20 ) serving as the winding starting end.
