für dieses Verfahren.for this procedure.

Nach der Patentschrift Nr. 88842, Kl. 12, wird der gaserzeugende Stoff schichtweise zwischen Scheibchen aus wasserdichtem Material angeordnet. Dabei ruht, wenn auch erst durch Vermittelung der Zwischenscheiben, eine Schicht auf der anderen, wodurch erreicht wird, dafs nach Netzung einer Schicht eine durch Capillarattraction mögliche Durchtränkung weiterer Schichten verhütet wird. Es soll nur in derjenigen Zeit, während welcher das Wasser beim Ansteigen eine erste Schicht ganz durchdringt, die nächste Schicht trocken bleiben. Ist diese erste Schicht ganz eingetaucht, so hat die Zwischenscheibe ihrer Aufgabe genügt; sie bildet nun einfach die wirkungslose Fufsscheibe der zweiten Schicht, durch deren Kopfscheibe sie in der gegen fortschreitende Capillarattraction gerichteten Isolirwirkung abgelöst wird. Mit voller Einsenkung einer Schicht ins Wasser hört also die Isolirscheibe an deren Kopfe auf, zu wirken. Nach vorliegender Erfindung werden zwischen die einzelnen Calciumcarbidschichten nicht Zwischenscheiben .geschaltet, sondern diese Schichten werden aus einander gerückt, derart, dafs zwischen ihnen Luftzwischenräume entstehen. Diese Zwischenräume haben die Bestimmung, zwischen die Einsenkung einer Schicht in das Wasser und das Herandringen des Wasserspiegels an eine weitere Schicht einen bestimmten Zeitzwischenraum zu schalten, und treten im Gegensatze zu den Scheiben nach Patentschrift Nr. 88842 erst in dem Augenblick in Function, wo die Einsenkung der schon genetzten Schicht ins Wasser gerade eine vollständige ist. Das Wasser kann jetzt um eine nicht unbedeutende Höhe weitersteigen, ohne ein neues Calciumcarbidelement in den Entwickelungsprocefs hineinzuziehen. Hierdurch gewinnt die völlig eingetauchte Schicht diejenige Zeit, welche zur rechten Influfsbringung des infolge der gänzlichen Durchtränkung eintretenden und zur völligen Erschöpfung der Schicht führenden letzten Aufschwunges der Gasabgabe nöthig ist, wobei letztere das Wasser unter Umständen noch einmal zum Zurückweichen bringen kann, also eine vorzeitige, überflüssige und unrationelle Durchtränkung einer weiteren Schicht verhindert. Da die Luftzwischenräume einstellbar sind, so kann ihre bremsende Wirkung der Schnelligkeit der Gasentwickelung auf Grund der Erfahrung angepafst werden. Die Bremsung hat ein Verhüten starker, unvermittelter, unter Umständen mit Gasverlust verknüpfter Schwankungen des Wasserstandes zur Calciumcarbidsäule und, davon abhängig, eine gleichmäfsige, ruhige Gasentwickelung zur Folge. Da ferner die Elemente gleichsam frei im Räume schweben, so kann das entwickelte Gas bequem allseitig entweichen, es braucht sich nicht erst durch eine darüberstehende Calciumcarbidsäule hindurchzuarbeiten. According to patent specification No. 88842, class 12, is the gas-generating substance is arranged in layers between discs made of waterproof material. A layer rests, albeit only through the intermediary of the intermediate panes on the other, whereby it is achieved that, after one layer is wetted, one by capillary attraction possible impregnation of further layers is prevented. It should only be in one Time during which the water completely penetrates a first layer as it rises, the next layer will stay dry. If this first layer is completely immersed, then it has the intermediate pane is sufficient for its task; it now simply forms the ineffective foot disk of the second layer, through whose head disc it is in the opposite direction of progressing capillary attraction directed isolating effect is replaced. With one layer fully immersed in the water so the insulating disk on their head ceases to work. According to the present invention no intermediate washers are inserted between the individual calcium carbide layers, but these layers are moved apart in such a way that there are air spaces between them develop. These gaps are intended between the sinking of a layer into the water and the water level reaching another layer for a certain period of time to switch, and in contrast to the discs according to patent specification No. 88842 only occur in function at the moment when the subsidence of the already wetted layer into the Water is just a full one. The water can now be a not insignificant one Rise in altitude without a new calcium carbide element in the process of development to pull in. As a result, the completely immersed layer gains the time it takes to Right inflation of the occurring as a result of the complete saturation and to the complete exhaustion of the shift leading to the final upturn in gas release is, whereby the latter can cause the water to recede again under certain circumstances, thus a premature, superfluous and inefficient impregnation of a further layer is prevented. Since the air gaps are adjustable, their braking effect can be the The speed of gas evolution can be adjusted based on experience. The braking has a prevention of strong, sudden fluctuations, possibly linked to gas loss of the water level to the calcium carbide column and, depending on this, an even, calm gas development result. Furthermore, since the elements float freely in space, in this way, the developed gas can easily escape on all sides, it does not need to get through first work a calcium carbide column above it.

Claims

Filling provided container a with completely perforated walls fz. B. made of wire gauze), which are packed on top of each other to form a column, with feet c on each container defining a certain air space between each two elements and also, as in the example shown, can be used to guide the containers against each other by, in engagement with the lid pin d, convey a mortise between the containers. If one thinks that a bell is put over this column in the known way, the whole thing is placed in a water vessel and the gas is being developed, then after the gas extraction, the water may rise up the column and a new element will be created by wetting can be used to generate gas. The water can then continue to stiffen without first reaching another element (even after the wetted element is completely immersed in the water). Until then, a period of time corresponding to the height of the air space between the elements elapses, during which the wetted element can effectively intervene in the gas development and possibly stop the rise of the water before the water reaches the next element, which causes excess gas generation would. Due to the air gaps there is a certain braking in the gas generation, which increases with the size of the air gaps. B. can be made adjustable by pull-out feet of the container. As mentioned, the containers are perforated on their entire wall to allow easy escape of the gas; to overflow they are also provided at the top with an open nozzle e through which the gas can flow freely into the spaces between the elements. In order to be able to carry the whole column comfortably, insert it and lift it out, it can be inserted into a corresponding lattice-shaped supporting structure. Then it is unnecessary to joint the containers with one another. If the calcium carbide could be shaped into solid blocks or discs, which would resist disintegration during the evolution of gas, the vessels could be avoided and the blocks could be built up directly to the column, leaving a gap (by means of suitable foot spacers). Pa τ ε ν τ - A ν s ρ R ü c η ε:

1. An amendment to the invention protected by patent no. 88842 in the Way that the gas-generating substance, in particular calcium carbide, is stored in layers on top of each other and between each two layers a gas space is left free.

2. An apparatus according to claim 1, characterized in that containers (a) perforated on all sides are combined to form a column and the distances between the gas-generating layers can be regulated by means of suitable elements (c).
