Granted: 1986-09-25
Abstract: An einer Gas-Hausanschlußvorrichtung mit einer aus einer Gewindebuchse, einer Spannschraube mit Axialausnehmung und Dichtelementen bestehenden Verbindungsvorrichtung für ein innerhalb des Hauses zu verlegendes Stahlrohr und ein außerhalb des Hauses verlegtes Kunststoffrohr soll die Aufgabe gelöst werden, auch Sicherheit im Bereich zwischen der Verbindungsvorrichtung und dem im Haus liegenden Absperrventil zu schaffen. Diese Sicherheit soll sowohl gegenüber unbefugte Eingriffe wirksam sein als auch gegen unbeabsichtigte Verstellungen oder Verdrehungen der an das Stahlgasrohr angebauten Armaturen. Die Erfindung löst diese Aufgabe dadurch, daß die Spannschraube auf dem Stahlgasrohr drehbar aber axial unverschiebbar gelagert ist, daß an dem Stahlgasrohr mindestens zwei Halter befestigt sind, die an ihren freien Enden Wandbefestigungselemente aufweisen und daß an der Buchse der Verbindungsvorrichtung und/oder an einem an der Buchse angebrachten Schutzrohr im einzumauernden Bereich Vorsprünge als Dreh- und Verschiebesicherung angebracht sind. Nach dem Einmauern bzw. Eingießen der Buchse der Verbindungsvorrichtung bzw. des an dieser Buchse angebrachten Schutzrohres in dem Kellermauerwerk und nach Anbringung des Halters an dem Stahlrohr und an der Kellerwand ist es nicht mehr möglich, die Spannschraube aus der Buchse herauszudrehen und somit die Verbindung zwischen dem Stahlgasrohr und dem Kunststoffgasrohr zu lösen.

Title: Verfahren zur dauerhaften Verformung von Haaren
IPC: A45D/
Filed: 1981-05-16
Granted: 1986-04-17
Abstract: Mehrstufiges Verfahren zur dauerhaften Verformung von Haaren, bei dem das Haar vor und/oder nach dem Aufrollen auf Wickler zunächst mit einem flüssigen haarkeratinreduzierenden Dauerverformungsmittel behandelt wird. Dieses flüssige, schwach verformungswirksame Dauerverformungsmittel vermag das Haar im Bereich der Haarspitzen zu verformen, ohne jedoch während der Einwirkungszeit die Haarspitzen zu schädigen. Anschließend wird auf die gewickelten Haare ein konsistentes haarkeratinreduzierendes Dauerverformungsmittel, das bei 30 ° C eine Viskosität von 50 bis 5000 m Pa   s, vorzugsweise 100 bis 500 m Pa   s, aufweist und eine gegenüber dem flüssigen Dauerverformungsmittel stärkere Verformungswirksamkeit besitzt, aufgetragen. Das konsistente Dauerverformungsmittel schirmt die Haare nach außen ab und verhindert so einerseits den Zutritt von Luftsauerstoff und andererseits das Entweichen eines flüchtigen Alkalisierungsmittels, wie z.B. Ammoniak. Weiterhin wird durch die höhere Verformungswirksamkeit des konsistenten Dauerverformungsmittels eine gute Umformung des Haaransatzes ohne die Gefahr einer Überkrausung der Haarspitzen erreicht. Nach einer ausreichenden Einwirkungszeit wird das Haar ausgespült und sodann mit einer oxidierend wirkenden Lösung behandelt.
