Description

Membran für Gasdruckfernzünder. Im Laufe der Jahre hat sich herausgestellt, daß Membranen aus Leder, Ballonstoff o. dgl., welche durch Fette, ,Öle oder Firnis gasdicht gemacht wurden, im Dauerbetrieb für Gasdruckfernzünder nicht standhielten. Das Gas oder seine Beimischungen zersetzte langsam das Leder o. dgl. und seine Dichtungsbestandteile, und die Membran wurde undicht und gasdurchlässig. Der Fernzünder mußte somit versagen und arbeitete nicht mehr. Bei Gasdruckfernzündern mit einem Hub von etwa z mm hat man sich dadurch geholfen, daß man Metallscheiben lamellenartig zusammensetzte und als Huborgan für Fernzünder mit sehr kleinem Hub benutzte. Bei Fernzündern mit hohem Hub von etwa bis 2o mm war dies nicht durchführbar, da eine derartig hohe Durchbiegung bei Metallmembranen technisch undurchführbar ist. Um dies zu erreichen, werden nach der Erfindung die Leder-, Stoff- oder sonstigen Membranen auf kaltem oder chemischem Wege fein metallisiert, z. B. nach dem Metallspritzverfahren. Die Membran behält durch diesen feinen Überzug, welcher ein- oder zweiseitig sein kann, ihre Geschmeidigkeit und läßt sich ohne weiteres für Fernzünder mit hohem Hub verwenden.Membrane for gas pressure remote igniter. Over the years it has been found that membranes made of leather, balloon material o. The like. Which by fats, oils or varnish were made gas-tight, did not withstand continuous operation for gas pressure remote igniters. The gas or its admixtures slowly decomposed the leather or the like and its sealing components, and the membrane became leaky and gas permeable. The remote detonator had to fail and no longer worked. With gas pressure remote igniters with a stroke of about z mm one helped oneself by assembling metal disks like lamellas and used as a lifting device for remote detonators with a very small stroke. For remote detonators with a high Stroke of about up to 20 mm, this was not feasible because of such a high deflection is technically impracticable for metal diaphragms. To do this, be after of the invention, the leather, fabric or other membranes on cold or chemical Paths finely metallized, e.g. B. after the metal spraying process. The membrane retains its suppleness thanks to this fine coating, which can be one or two-sided and can easily be used for remote detonators with high lift.
