The invention relates to a method for protecting street furniture against the effect of fireworks. For this purpose cavities, recesses, gaps and the like in the street furniture are where possible filled. This preferably takes place by placing attachments such as filler piece (4) in the cavities, recesses, gaps and the like and subsequently securing these attachments.

Eine Vorrichtung zur Entsorgung gefährlicher oder hochenergetischer Materialen umfasst ein druckfestes Aussengehäuse (2), in dem die Materialien unter kontrollierten Bedingungen zu einer Reaktion gebracht werden können, deren Endprodukte ungefährlich sind. In dem Außengehäuse (2) bewegt sich von oben nach unten ein Wanderbett, welches im dynamischen Gleichgewicht zwischen der Zufuhr eines Schüttgutes und den zu entsorgenden Materialien einerseits und dem Austrag einer Mischung aus Schüttgut und der Reaktion entstammender Produkte andererseits ausgebildet ist. In dem Wanderbett ist mindestens eine Schikane (6) vorgesehen, welche einen Kernbereich, in dem sich das Wanderbett im wesentlichen unbehindert axial nach unten bewegt, umgibt und in einem den Kernbereich umgebenden Ringbereich die axiale Bewegung des Wanderbettes verzögert. Auf diese Weise lässt sich die Menge des im Umlauf befindlichen Schüttgutes reduzieren, was den Gesamtenergiehaushalt der Vorrichtung günstig beeinflusst. Die Schikane (6) schützt zudem die Wand des Aussengehäuses (2) und bietet die Möglichkeit, an einer dem Kernbereich, wo die Reaktionen stattfinden, nicht unmittelbar zugewandten Fläche einen Sensor (8) unterzubringen, der die physikalischen Bedingungen im Reaktionsbereich misst, und gegebenenfalls Zufuhrleitungen für Hilfsstoffe, beispielsweise Heiz- oder Kühlgase oder Chemikalien.
摘要:
A method for treating an object by exploding a blasting powder layer formed on the outer surface of the object having a shell of a specified shape. The blasting powder layer has a first blasting powder layer formed on the outer surface of the shell and a second blasting powder layer so formed as to surround the first blasting powder layer. The blasting powder of the second blasting powder layer has a detonation velocity higher than that of the blasting powder of the first blasting powder layer. The second blasting powder layer and the first blasting powder layer are blasted with a time difference by igniting a specified part of the second blasting powder layer. The scattering impact of the shell is relaxed, and the blasting treatment can be carried out at a low cost.

The present invention relates to a new method for providing a destruction or detonation chamber (1, 9 and 27) intended for the destruction of ammunition products and other explosive products with an easily replaceable internal detonation and fragmentation protection (23-25). A particular characteristic of the detonation and fragmentation protection (23-25) according to the invention is that it comprises a large number of identical segments, which can take the form of a small number of interacting and mutually complementary variants, and which are all characterized in that they are relatively easy to handle and can be delivered to the interior of the destruction chamber (1, 9 and 27), where they are fitted in place through the closeable aperture (29), which in operation of the destruction chamber is used to charge the explosive material that is to be destroyed therein.

L'invention a pour objet un système de protection pour dispositif contenant une matière réagissant violemment à un échauffement, comportant un profilé (14) et un senseur (13) permettant d'activer ledit profilé (14), caractérisé en ce qu'il comporte un réservoir principal (11) contenant une substance (12) susceptible d'exploser, et au moins un premier conduit (112) permettant d'alimenter pour l'activer, le profilé (14) avec ladite substance (12). L'avantage de l'invention réside dans l'éloignement de la substance (12) susceptible d'exploser par rapport au dispositif muni du profilé (14).
摘要:
The present invention relates to a method of working up and recovering returned explosives which are principally of the military type and which contain both fusible and non-fusible crystalline substances. In accordance with the invention, the returned explosive is treated in a multi-stage process which includes a first leaching stage for removing the non-crystalline, preferably fusible, component of the explosive in the form of trotyl, wax or plastic. The substance used in the leaching stage, principally toluene, does not affect the crystalline components of the explosive. The collected leaching liquid is separated off and the toluene, together with its dissolved content of trotyl or wax, is conveyed onwards for working up. The toluene which is recovered during the working up is returned to the process while the remaining filtrate from the filtration stage is treated with solvent which dissolves the crystalline high-energy explosives octogen and hexogen, respectively, which are relevant in this connection, which explosives, in a subsequent process stage, are precipitated out in the form of new crystals which, after a possible recrystallization, are ready to be reused. The solvent which is used in this connection is returned to the process.
摘要:
The claimed device is intended for use in destroying explosive objects, including objects placed in inaccessible places, without triggering a full-scale explosion and without any preliminary diagnostic investigation. A non-rupturing casing (1) open at two opposite ends accommodates the following elements arranged one after the other: a shattering device (2) in the form of a packet of high-strength rods; a propollant (3) in the form of an expolosive charge; end a wave suppresser (5). When the propellant (3) is detonated, the energy of the explosion drives the rods of the shattering device (2) towards the explosive object (7) at a speed sufficient to destroy the principal elements of the object's explosive device without triggering a full-scale explosion.
