Description
PATENTANSPRUCH: Vorrichtung zum Feststellen von Gasaus strömungen aus Gasleitungen und Behältern mit einem äußeren, zur Oxydation von Kohlenoxyd dienenden und einem inneren, von jenem umgebenen Katalysator nach Zusatzpatent 640507, dadurch gekennzeichnet, daß der innere röhrchenförmig ausgebildete und mit konischen, die Oberfläche und Strömungsmöglichkesiten wesentlich vergrößernden Durchbohrungen versehene Katalysator (4) unmittelbar von dem äußeren, körnigen Katalysator (6) allseitig umgeben ist, der von einem fein gelochten Glimmerkorh (7) zusammengehalten und erst in geringem gleichmäßigem Abstand von einem explosionssicheren Körbchen aus feinmaschigern Gewebe (8) abgeschlossen wird. PATENT CLAIM: Device for detecting gas outflows from gas pipes and containers with an outer one used for the oxidation of carbon oxide and an inner catalyzer surrounded by that additional patent 640507, thereby characterized in that the inner tube-shaped and conical, the Surface and flow possibilities are provided with holes that enlarge significantly Catalyst (4) directly from the outer, granular catalyst (6) on all sides is surrounded, which is held together by a finely perforated mica core (7) and only at a small, even distance from an explosion-proof basket made of fine mesh Tissue (8) is completed.
