Patent number: 4967549Abstract: 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.Type: GrantFiled: July 25, 1989Date of Patent: November 6, 1990Assignee: Schubert & Salzer Maschinenfabrik AktiengesellschaftInventors: Kurt Lovas, Wolfgang Gebhardt, Heinz Leipnitz

Patent number: 4676302Abstract: The invention relates to a collecting device for cleaning members at the outlet of a heat exchanger, which is directly connected or, after passing through spacers or a bend, is reached by the flow from the outlet. In order to avoid speed peaks, in the often inhomogeneous flow, an intake aid is provided at the discharge point of the outlet, which is intended to render to flow uniform. As a result the screens conventionally used in the collecting device can have a smaller angle of inclination, which has an advantageous effect on the space requirements and the manufacturing costs.Type: GrantFiled: October 4, 1985Date of Patent: June 30, 1987Assignee: Taprogge GmbHInventor: Wolfgang Gebhardt
