摘要： An apparatus for bringing to rest the rotor of an open-end spinning apparatus which is covered by a cover. The rotor is mounted in a wedge gap formed by freely rotatably support rollers and pressed against the support rollers and driven by a tangential belt. An axial force arising from the support rollers presses the rotor against an axial stop. A lever is provided for lifting the shaft off of the support rollers and against stops for arresting the rotation of the rotor. Compressed air is applied to the rotor when the rotor is being brought to rest for maintaining the shaft of the rotor against the axial stop.

摘要： A method and device for cleaning a rotor in an open-end spinning machine. While the rotor is running at a speed less than the normal r.p.m. a first flow of cleaning air is directed to a collecting groove of the rotor and a second flow of cleaning air is simultaneously directed to the periphery of the spinning rotor at an angle different from the first flow of air. In one embodiment, at least one of the flows of air is directed in a pulsating manner. The flows or streams of air are fed through ducts provided in an extension of a cover which extends within the rotor or is supplied to the rotor by means of a movable housing.

摘要： A method and apparatus for individually piecing up yarn on an open-end spinning machine which has a spinning rotor and a rotor brake. A rotor cleaning apparatus is carried on a pivotal cover and is used for cleaning the rotor responsive to being activated. A pivotal lever which when moved relative to the cover simultaneously activates the rotor cleaning apparatus and the rotor brake causing the rotor to be cleaned as the rotor is being stopped. The yarn is pieced up when the rotor is being brought back up to running speed.

摘要： The invention contemplates a process for the crystalline precipitation of a chromogen from solution thereof in a solvent and within a capillary. The process involves first initiating a course of crystalline precipitation of the chromogen by initially and locally supersaturating the solution within the capillary, and thereafter evaporating the solvent at a rate and in an environment sufficient for further crystallization to proceed unimpeded by local supersaturation.

摘要： In an open-end spinning device with a spinning rotor a compressed air conduit is provided for directing an air current upon the inner surface of the spinning rotor. This compressed air conduit is connected through a stop valve to a source of compressed air. The compressed air conduit is provided with a pressure control device which can be pre-set to at least two pressure levels. The pressure control device has parallel conduits of which one conduit is provided with a pressure reduction device for the low pressure.During the preparation of the piecing operation, compressed air, at high pressure, is fed into the spinning rotor to clean said spinning rotor. Subsequently, but before the start of fiber feeding into the spinning rotor, the compressed air is reduced to a lower pressure value and is finally switched off before the yarn is fed back into the spinning rotor.The invention includes the process for restarting the open-end spinning device. Both the process and the device may be manually or automatically operated.

摘要： A pair of draw-off rollers (10, 11) of a thread drawing-off device comprising an over-mounted pressure roller (11) which cooperates resiliently with a driven roller (10) which projects across the front of the pressure roller (11). The pressure roller (11) has at least one recess (113, 114) on its front face (110) which is dimensioned in such a way that it temporarily completely releases a thread (4) sliding along the surface of the driven roller (10) and lying adjacent to the front (110) of the pressure roller (11). By means of a device of this type, the thread (4) is drawn off, for the purposes of joining, to such an extent from the spool (31) that the thread (4) reaches the side (310) of the spool (31) which is facing away from the front (110) of the pressure roller (11) provided with recesses (113, 114). The thread is then introduced into the spinning chamber (2) and is joined. The thread is then guided, using the thread tension, past the front (110) of the pressure roller (11) provided with recesses (113, 114) and introduced into the clamping line of the pair of draw-off rollers (10, 11) and is immediately subjected at this point to a predetermined draw-off.
