Description

Najdluzszy czas trwania patentu do 17 listopada 1941 r.W patencie Nr 6312 opisano nabój lub ladunek wybuchowy, zawierajacy powie¬ trze plynne, palny proszek metaliczny i palny pochlaniacz organiczny, który moz¬ na przepoic powietrzem plynnem.Wynalazek niniejszy dotyczy wytwa¬ rzania i uzycia tego rodzaju srodka wybu¬ chowego, w którym proszek metaliczny lub mieszanine kilku palnych proszków meta¬ licznych zastapiono czesciowo lub calko¬ wicie pylem z wielkich pieców, zmiesza¬ nym z solami ochladzajacemi, jak np. chlo¬ rek lub weglan sodowy i t. d.Nabój utworzony w sposób wskazany powyzej nadaje sie szczególnie dla kopal¬ ni wegla.W celu unikniecia tworzenia sie tlen¬ ku wegla w chwili wybuchu naboju prze¬ pojonego powietrzem plynnem nabój za¬ opatruje sie w powloke z tworzywa obo¬ jetnego, np. z papieru azbestowego lub pa¬ pieru niepalnego, W pewnych wypadkach ponadto, dla o- stroznosci, zwilza sie scianki otworu roz¬ tworami soli ochladzajacych. Dla spotego¬ wania sily kruszacej srodka wybuchowe¬ go wystarczy dodac nieznaczne ilosci ja¬ kiegokolwiek weglowodoru. PL PL PLThe longest patent period lasted until November 17, 1941. Patent No. 6312 describes a cartridge or explosive charge containing liquid air, a flammable metal powder and a flammable organic absorbent which can be impregnated with liquid air. The present invention relates to the manufacture and use of such an explosive in which the metal powder or a mixture of several flammable metal powders is replaced partly or completely by blast furnace dust mixed with cooling salts, such as sodium chloride or sodium carbonate, etc. A cartridge formed in the manner indicated above is particularly suitable for coal mines. In order to avoid the formation of carbon monoxide upon explosion of a cartridge impregnated with air, The liquid cartridge is then provided with a coating of an inert material, e.g., asbestos paper or non-flammable paper. In some cases, as a precaution, the walls of the hole are also wetted with cooling salt solutions. To increase the crushing power of the explosive, it is sufficient to add small amounts of any hydrocarbon. PL PL PL
