Patent WO-0205600-A1 (WO)
Inventor: BOENIGK MICHAEL
IPC: H05B41/288
Filed: 2001-07-09
Abstract: Natrium-Hochdrucklampen können mit einer Schaltungsanordnung betrieben werden, die die Netzwechselspannung gleichgerichtet und unter Verzicht auf Glättung direkt einem Wechselrichter zur Erzeugung einer Frequenz oberhalb 1 kHz zuführt. Die mit dem Zweifachen der Netzfrequenz modulierte Spannung wird über eine HF-Induktivität und einen Zündübertrager der Lampe zugeführt, die vorzugsweise eine Xenonfüllung oberhalb 1 bar enthält. Die Einsparung an Elektroenergie für das System Lampe - Vorschaltgerät beträgt 30 % im Vergleich zu einer drosselbetriebenen Hg-freien Standartlampe bei gleichem Lichtstrom. Die Verwendung eines Mikroprozessors für die Steuerung der Halbbrücke ermöglicht eine fremdgesteuerte oder automatische Leistungsabsenkung mit einem weiteren Energieeinsparungspotential von 35 % im Jahresmittel sowie eine End of Life-Abschaltung des Systems zur Vermeidung von Cycling.

Title: Nozzle for plastic extrusion
Inventor: ARTHUR NIER ERICH
IPC: B29C45/20
Filed: 1968-11-15
Abstract: Injection moulding nozzle with variable resistance to flow and with positive cut-off by means of stop cock With advantage, partic. for foaming plastics, where it may be required to generate high internal resistance to flow in the nozzle to prevent premature foaming in the nozzle, and to cater for the variable properties of moulding materials, and also where it may be desirable to reduce the volume of expansion to the maximum after injections, making positive cut-off of the nozzle flow desirable. The nozzle is thus provided with a plug-cock to give positive cut-off, and also with an axially adjustable internal conical core section, within the conical cross section of the nozzle, the core is movable by a system of threaded sections, varying the annular cross section of flow.
