KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In den bekannten Schaufenstern sind die ausgestellten Waren vielen nachteiligen Einflüssen
ausgesetzt, insbesondere verlieren die Erzeugnisse der Textilindustrie, welche dem
Publikum zur Erhöhung der Kauflust gezeigt werden, infolge Ausbleichens bald ihren Wert,
wodurch je nach der Größe des Geschäftes unbedingt Verluste hervorgerufen werden.
Durch Versuche hat sich herausgestellt, daß diese nachteiligen Wirkungen in der Hauptsache
nicht allein durch die darauffallenden Sonnenstrahlen, sondern auch durch den Sauerstoff
der atmosphärischen Luft bewirkt werden. Man hat schon diesen Übelstand dadurchIn the well-known shop windows, the goods on display are exposed to many adverse influences, in particular the products of the textile industry, which are shown to the public to increase the willingness to buy, soon lose their value as a result of fading, which, depending on the size of the shop, necessarily causes losses.
Experiments have shown that these adverse effects are mainly caused not only by the rays of the sun falling on them, but also by the oxygen in the atmospheric air. You already have this disadvantage because of it
J5 zu beseitigen versucht, daß die atmosphärische Luft in dem Schaubehälter, welcher zu diesem Zwecke vollkommen luftdicht geschlossen ausgeführt ist, durch einen indifferenten Stoff, z.B. Kohlensäure oder Stickstoff, ersetzt wurde, nachdem vorher durch Durchspülen die Luft entfernt worden war. Nach der Erfindung wird das Eindringen der Luft dadurch verhindert, daß man in dem Schaufenster einen möglichst gleichbleibenden, geringen Überdruck hält. Zwecks Erhaltung eines solchen Überdruckes steht der luftdicht geschlossene Schaufensterraum mittels eines selbsttätig arbeitenden Regulierventils mit einem Stickstoffbehälter in Verbindung, wobei das Regulierventil die Aufgäbe erfüllt, beim Sinken des Überdruckes bis zu einem gewissen Punkte den Stickstoff nachströmen zu lassen und bei Erreichung eines bestimmten Höchstüberdruckes die Zuführung des Stickstoffes wieder abzusperren. J 5 tries to eliminate the fact that the atmospheric air in the viewing container, which is designed to be completely airtight for this purpose, was replaced by an inert substance, e.g. carbonic acid or nitrogen, after the air had previously been removed by purging. According to the invention, the ingress of air is prevented by maintaining a low overpressure that is as constant as possible in the shop window. In order to maintain such an overpressure, the airtight closed shop window is connected to a nitrogen tank by means of an automatically operating regulating valve, the regulating valve fulfilling the task of allowing the nitrogen to flow in up to a certain point when the overpressure drops and the supply when a certain maximum overpressure is reached shut off the nitrogen again.
Eine beispielsweise Ausführungsform der Erfindung ist in der Zeichnung schematisch dargestellt, und zwar bezeichnet s den Schaufensterkasten, α den Stickstoffbehälter, ν ein Regulierventil und m einen Überdruckanzeiger. Der Stickstoffbehälter ist eine handelsübliche, mit hochgespanntem Stickstoff gefüllte Stahlflasche. Die Spannung wird durch ein oder mehrere Regulierventile auf den erforderlichen Druck herabgebracht. Den im Schaufensterkasten herrschenden Überdruck kann man an dem Überdruckanzeiger m ablesen. Die durch irgendwelche· Undichtigkeiten entweichenden Stickstoffgase werden durch die beschriebene Anordnung stets ergänzt, so daß keine Außenluft eintreten kann.An example embodiment of the invention is shown schematically in the drawing, namely s denotes the shop window box, α the nitrogen container, ν a regulating valve and m an overpressure indicator. The nitrogen container is a standard steel cylinder filled with high pressure nitrogen. The tension is brought down to the required pressure by one or more regulating valves. The overpressure in the shop window can be read from the overpressure indicator m . The nitrogen gases escaping through any leaks are always supplemented by the arrangement described, so that no outside air can enter.
