Push-on fitting () for a push-on suction cup () for a conveyor belt () for transporting or lifting goods, which push-on fitting () comprises a base disc () having a front side () and a rear side () and being adapted to be mounted in a hole () of the conveyor belt (), said base disc () having a hole () for through airflow and being provided with a hollow push-on snap fitting pin () for through airflow, said pin () extending outwardly essentially perpendicular to the front side () and adapted to receive a push-on suction cup (), wherein the snap fitting pin () comprises at least a pair of axial slots () adapted to provide at least a pair of flexible tongues () formed in an end () of the pin () and in that the flexible tongues comprise a concentric snap fitting rim () having a variable diameter (D), that can be varied by an end () part of the flexible tongues () being acted upon, for receiving the push-on suction cup () provided with a washer () having a mounting hole () with a diameter (D) smaller than a largest diameter (D) of the rim ().

Fitting for suction cup and suction cup

The present invention relates to a device for adjusting the beam direction of a beam radiated from a stationary array of antenna elements. Antenna element feed points are coupled to a common source via a feed line structure having a source connection and feed connection terminals to be connected to the antenna element feed points, the feed line structure being at a distance from and in parallel to a fixed ground plane. A movable element is located adjacent to the feed line structure to change the signal phase of signal components being transferred between the source connection and the respective feed connection terminals. The movable element is movable for effecting a phase shift of the signal components to adjust the beam direction. The device is provided with a detection arrangement for detecting the absolute position of the movable element.
