Flüssige Luftverwertungsgesellschaft m.b.H. in Charlottenburg. Verfahren zur Herstellung von Patronen für das Sprengen mit flüssiger Luft.Liquid air recycling company m.b.H. in Charlottenburg. Process for the manufacture of cartridges for blasting with liquid air.

Patentiert im Deutschen Reiche vom 28. Mai 1913 ab.Patented in the German Empire on May 28, 1913.

Es ist bekannt, die Masse für Sprengluftladungen oder -patronen in eine feste, steife Papphülse (Umhüllung) zu fassen. Diese Einfassung ist sehr teuer, für flüssige Luft schwer durchlässig und nicht nachgiebig. Diese Übelstände kann man dadurch beseitigen, daß man die Sprengluftmasse in eine nachgiebige Hülle aus beliebigem Stoff einschließt. Eine so hergestellte nachgiebige Patrone ist in ihrer Herstellung billiger, paßt sich beliebig besser an und gibt insbesondere der nicht gesättigten Patrone eine bessere Handhabungsmöglichkeit. Ferner ist eine solche nachgiebige Patrone zum Aufsaugen flüssiger Luft besser geeignet, wobei man geeignetenfalls diese bessere Wirkung noch durch Anordnung von Löchern oder Kanälen weiter fördern kann, damit die flüssige Luft noch leichter die Masse durchdringen kann.It is known that the mass for explosive air charges or cartridges is made into a solid, stiff one To grasp cardboard sleeve (wrapping). This enclosure is very expensive, heavy for liquid air permeable and not yielding. These evils can be eliminated by encloses the blasting air mass in a flexible envelope made of any material. One made in this way compliant cartridge is cheaper to manufacture, adapts itself better as desired and in particular gives the unsaturated cartridge easier to handle. Furthermore, such a resilient cartridge is better suited for sucking up liquid air, where appropriate, this better effect can be achieved by arranging holes or channels can further convey so that the liquid air can penetrate the mass even more easily can.
