  • Publication number: 20210116289
    Abstract: Various embodiments include a system for determining a filling level of a fluid comprising: a fluid container with a first wall, a second wall opposite the first, and a bottom; a transducer mounted outside the first wall at a predetermined distance from the bottom, the transducer transmitting an ultrasonic signal through the first side wall into the fluid container; a reflection element inside the fluid container reflecting the signal back to the transducer; and a control device for activating the transducer. The control device identifies a current fluid filling level greater than a minimum filling level if the signal received by the transducer is an ultrasonic signal reflected by the reflection element, and identifies a fluid filling level less than the minimum filling level if the transducer does not receive an ultrasonic signal or receives an ultrasonic signal reflected by the first side wall.

  • Publication number: 20210053792
    Abstract: The subject matter of the invention is a manual multispool cabinet for winding a number of filaments (40, 40a) onto a respective removable transport spool (14, 14a) having a driven main winding shaft (10, 10a) per transport spool (14, 14a), wherein the main winding shaft (10, 10a) is formed for an exactly fitting reception of the transport spool (14, 14a, 214), and wherein the main winding shaft (10, 10a) drives the transport spool (14, 14a). Providing such a manual multispool cabinet that has such an increased filament speed is achieved in that, in addition to the transport spool (14, 14a), a buffer spool (12, 12a) is held on the main winding shaft (10, 10a).
