A method and device for enhancing the vapor sterilization of the lumen of medical instruments and like articles under reduced pressure. A vessel containing a small amount of a vaporizable liquid antimicrobial solution is attached to the lumen. The antimicrobial vaporizes and flows directly into the lumen of the article as the pressure is reduced for the sterilization cycle. Preferred embodiments i...

In an arrangement for application in open-end rotor spinning, an opening roller is housed in a swivel housing. The swivel housing can, together with the assembled opening roller, be removed from the arrangement for open-end rotor spinning when the machine is in operation. The opening roller, due to its mass, continues to rotate after it has been separated from the tangential belt which drives it. ...

A process is disclosed for a spinning arrangement for dealing with the correction of an end break. During operation, sliver-like fiber material fed to the spinning arrangement is opened to single fibers by means of an opening roller. The single fibers are then transferred in the form of a fiber veil to a suctioned collecting surface, which is driven in the direction of motion of the single fibers....
