  • Patent number: 6390125
    Abstract: A manually-operated valve is provided in series with an electromagnetically-operated valve and the manually-operated valve is provided with a proximity detector connected to the electronic controller whereby a switch in the manually-operated valve, in one position of the single control lever therefor, corresponding to about 50% of maximum supply rate, is operated to activate the proximity sensor and enable the water flow to be controlled by an object within its detection range. Removal of the object, e.g. the hand of the user from the range, will shut off the water through the manually-operated valve. Outside the position of the lever at which the switch is operated, the proximity detector is ineffective and control is effected exclusively by swinging the lever.

  • Patent number: 5373690
    Abstract: With pneumatic feeding of fibers to the fiber collection surface of an open-end spinning element, an auxiliary air stream flowing from the immediate proximity of the feeding device to the inlet into the fiber feeding channel is produced and is sufficiently strong so that it removes circling fiber fragments which have been detached from the opener roller. For this purpose, an air conveying channel is provided in the area between the inlet opening of the fiber feeding channel and the feeding device (as seen in the direction of rotation of the opener roller) in the peripheral wall of the housing. This air conveying channel extends from the immediate proximity of the opening in the housing containing the feeding device in housing to the inlet opening of the fiber feeding channel.

  • Patent number: 5361574
    Abstract: In conveying fibers (20) pneumatically to the fiber collection surface of an open-end spinning element, the fibers (20) fed into the fiber feeding channel (4) are detached from the wall (42) of the fiber feeding channel (4)which follows the fiber-guiding peripheral wall (12) of the opener roller (10) preceding the fiber feeding channel (4) and are fed to the zone of high flow speed. For this purpose the concave peripheral wall (12) preceding the fiber feeding channel (4) merges via a convex surface (41) of such configuration and length into the wall (42) of the fiber feeding channel (4) that a tangent (43) applied to the end of the concave peripheral wall (12) preceding the fiber feeding channel (4) intersects the opposite wall (420) of the fiber feeding channel (4).

  • Patent number: 4967549
    Abstract: A device for the storage of a yarn of limited length spun on a spinning machine, comprising a suction pipe and a yarn storage chamber. The suction pipe is connected to a negative-pressure line and serves to seize the yarn by means of suction air. The yarn storage chamber is located between the negative pressure line and the suction pipe. The yarn can be aspirated into the yarn storage chamber and can be drawn off once more in the direction opposite to the direction of aspiration. The yarn storage chamber is located in a body which is rotatably mounted.In the process for the storing of the yarn, the yarn is seized by the stream of suction air and is sucked through the suction pipe into the yarn storage chamber. The yarn is accumulated against the screen surface of the yarn storage chamber until the stream of suction air in the suction pipe is weakened to a point where additional aspiration of more yarn is prevented.
