Description

Blitzlichtlampe Die Erfindung bezieht sich auf eine Blitzlichtlampe, bei der der aus Metall oder Metallegierungen - bestehende Blitzlichtstoff und ein mit .ihm unter aktirischer Wirkung reagierendes Gas in einem gasdicht geschlossenen Gefäß enthalten sind. Bei den bekannten Lampen dieser Art muß das Metall in der Form sehr dünner Folien oder Drähte verwendet werden. Um ,ein blitzartiges Abbrennen zu gewährleisten, müssen die Foliem oder Drähte von einer solchen Feinheit sein, daß ihre Herstellung und besonders auch ihre Handhabung Schwierigkeiten bereitet.Flash lamp The invention relates to a flash lamp, in which the made of metal or metal alloys - existing flash material and a with .ihm reacting gas under active effect in a gas-tight closed Vessel are included. In the known lamps of this type, the metal must be in the Form very thin foils or wires can be used. Um, a flash of burning to ensure that the foil or wires must be of such a fineness that that their production and especially their handling causes difficulties.

Um diese Nachteile zu vermeiden, hat nach der Erfindung der Blitzlichtstoff poröse, schwammartige Struktur. Es ist schon vorgeschlagen worden, Folien schaumartiger Beschaffenheit aus Blitzpulvergemischen, z. B. Magnesium und Chlorat, herzustellen, doch können diese 'wegen des explosionsiaregen Verbrennungsvorgangs in geschlossenen Gefäßen nicht verwendet werden.In order to avoid these disadvantages, according to the invention, the flash material has porous, spongy structure. It has already been proposed to make foils more foam-like Consistency from lightning powder mixtures, e.g. B. Magnesium and Chlorate, to produce but they can be closed because of the explosive combustion process Vessels are not used.

Metallschwämme gemäß der Erfindung lassen sich auf mehrfache Art -herstellen. Es ist z. B. möglich, Aluminium durch Behandlung von Tonerde und Kohle mit Kohlensäure in einem geschlossenen, erhitzten Gefäß in Form einer porösen; schwammartigen Masse zu gewinnen. Auch kann das zu, verwendende Metall amalgamiert und das Quecksilber durch Erhitzen des Amalgams entfernt werden. Es ist ferner möglich, .das Metall mittels Kathödenzerstäubung auf eine Steinsalzkristallplatte niederzuschlagen und die letztere mit Wasser wegzulösen. Ein einfacher Weg besteht ferner darin, das Metall, z. B. Magnesium, mit einer wäßrigen Lösung von Dextrin, Gummiarabikum oder ähnlichen Bindemitteln zu anisichen, wobei eine leichte Reaktion und.-eine Volumenvergrößerung eintritt. Die Herstellung und Handhabung derartiger schwammartiger Massen ist billiger und einfacher als die bisher verwendeten Folien oder Drähte. Es ist dadurch auch möglich, das gegenüber dein Aluminium eine stärkere aktinische Wirkung ,aufweisende Magnesium zu verwenden, während es andererseits bisher nicht gelungen ist, Folien oder Drähte von genügender Feinheit aus diesem Metall herzustellen.Metal sponges according to the invention can be produced in several ways. It is Z. B. possible, aluminum by treating alumina and coal with carbonic acid in a closed, heated vessel in the form of a porous; spongy mass to win. The metal to be used can also be amalgamated and the mercury can be removed by heating the amalgam. It is also possible. The metal to precipitate by means of cathode atomization on a rock salt crystal plate and dissolve the latter with water. Another easy way is to use the Metal, e.g. B. magnesium, with an aqueous solution of dextrin, or gum arabic to anisichen similar binders, with a slight reaction and.-an increase in volume entry. The manufacture and handling of such sponge-like Mass is cheaper and simpler than the foils or wires previously used. This also makes it possible for aluminum to have a stronger actinic Effect of using magnesium, while on the other hand it has not so far has succeeded in producing foils or wires of sufficient fineness from this metal.
