Abstract: Some aspects relate to an apparatus for detecting an edge of a material web. In some examples, the apparatus comprises an ultrasound sensor which comprises two or more separately readable ultrasound receiver elements and an ultrasound transmitter element, wherein the ultrasound transmitter element is designed and arranged such that it applies an ultrasound measurement signal to two or more of the ultrasound receiver elements.

Abstract: The universal joint coupling comprises a housing (20) in which a torque transmitting pair of coupling members is arranged between two axial force transmitting pairs of coupling members (22, 24), each of which includes a spherical cup (22) and a ball segment (24) supported therein. The torque transmitting pair of coupling members (26, 28) has grooves which are arranged in two concentric rows and are defined by gaps in an internal gear ring (26) fitted into the housing (20), or an external toothing (28). They cooperate for torque transmission with counter-acting bodies, the profile of which matches the groove profile. Both the external toothing (28) and the ball segments (24) form part of a hub (16).
