Abstract: A retention chuck for glass pipes for machines producing glass containers is provided. The retention chuck has a central supply channel for the glass pipes, a plurality of adjustable clamping jaws arranged at the lower end of the supply channel and so as to be distributed around a centerline of the channel. The spacing of the jaws from the center line of the supply channel is adjustable by an actuation element. A coupling element couples the jaws to the actuation element. Guides guide the adjustment movement of the clamping jaws perpendicularly, radially inwardly relative to the center line.

Abstract: A hot-forming tool for producing glass containers is provided. The tool includes a forming roller, a holder, and a heat sink. The forming roller has a forming surface. The holder receives the forming roller with the forming roller rotatably mounted on the holder. The heat sink is directly or indirectly connected to the holder. The forming roller is in thermal contact with the heat sink and the heat sink has an internal cooler so that process heat can be transferred from the forming roller to the heat sink.

Abstract: An electronic system having an assembly of a plurality of electronic devices each driven by a local power unit and a power sequencer control circuit for controlling the power on or off operation of the local power units. The electronic devices can be for example display units of a display wall. An advantage of such an assembly, e.g. a tiled display or display wall, is that a low level or as little energy as possible is dissipated by the local power units such as DC power supplies associated with the electronic devices, e.g. tiles of a display, and the associated “housekeeping” electronics. A further advantage is a limitation of the inrush current at start-up.
