Patented in the German Empire on November 5, 1910.

The storage and transportation of low-boiling liquid gases show up to now there are still great inconveniences, and the storage of such liquid gases is special until now has been very limited because those previously known and exclusive for this purpose The evacuated glass vessels that have been used, in addition to their great fragility, still have the disadvantage

ίο that you only have a small capacity can give. Useful results in the manufacture of metal vessels have not yet been achieved, namely because the evaporation is far too big, and because you have a vacuum in height like it Is eligible for insulation because of the porosity the metal has not maintained can.

According to the present invention, there is now the possibility of using metal vessels not only to obtain just as good insulating properties as glass vessels (10 to 12 percent), but a far better one (around 5 percent).

The invention consists in the fact that in a metal vessel used to store and transport liquid gases and to isolate other bodies, the neck of the inner vessel, which is only to be calculated for tensile stress, is very thin-walled and slightly flexible in order to restrict the heat transfer, so that the inner vessel is placed against the outer vessel wall with a slight inclination, so that the neck is completely relieved and the increased evaporation necessary for expelling the contents is achieved, while the weight of the inner bottle and its contents when hanging or setting up the vessel is approximately vertical returns the position necessary for good storage or prevents the walls from being touched. . , ^;

An embodiment of the subject matter of the invention is shown in the accompanying drawing shown, namely shows

Fig. Ι a section through the vertical and

Fig. 2 shows a same section through the folded vessel. '

It is χ the outer metal ball limiting the vacuum and y the inner ball. The neck m , preferably made of manganese steel, has a very thin wall thickness. This neck is calculated in such a way that the inner sphere y, even with a very slight inclination, is inserted with its curvature in the corresponding curvature of the outer sphere; this results in not only partial, but complete relief of the neck and at the same time increased evaporation of the vessel contents (liquid air, liquid oxygen, liquid hydrogen, etc.). Such an arrangement is very important in the interest of a good discharge despite the 6g small neck diameter, because the vapors that develop when the inner ball is placed into the outer sphere drive the liquid out at increased speed, while otherwise the discharge is very much due to the enormous insulating capacity of the vessel would be more deficient

Claims (1)

Placing the inner ball in the outer one has two main advantages with itself: Firstly, the complete relief of the neck and secondly, through the supply of heat conditional accelerated expulsion of the liquid by the in the interest as possible low heat input, neck held relatively tight. Centered when erecting the vessel ίο the inner sphere back into the outer one inside, and the distance between the two walls delimiting the vacuum space is again consistently the same. There are both glass and metal vessels for support the inner ball supports or stops have been suggested by the course such a complete relief of the neck can never be achieved; and the Also, due to the low heat input through the supports, the contents are unable to expedited to drive out. All proposals in this regard are pending in addition, to obtain as little heat input as possible, through as little heat as possible Cross-section of the supports and the touching surfaces or poorly thermally conductive Materir.les should be achieved. With the subject matter of the invention the opposite means are used, despite the very narrow neck, when tilting the vessel the desired to get rapid discharge Any gas absorbent material attached to u is used to maintain a high vacuum at all times. However, it is important to ensure that, because of the relatively large porosity of the metal, a substance is used that has a stronger gas-absorbing effect than the substances used in glass vessels. The weight of the absorbent material to be introduced must also be as low as possible, since any reduction in the weight of the inner sphere is beneficial in the interests of durability. '. The container is not tied to a specific shape. The cylindrical or any a different shape always allows the inner jacket to be placed in the surrounding outer jacket Coat too. The excellent relief of the neck by placing the inner bottle into the outer and the resulting reduction in diameter and material cross-section of the neck in connection with a substance used to maintain an excellent vacuum have produced results that overshadow what has been achieved so far, because with one The test vessel located near the inventor evaporates only 5 to 6 percent of liquid air in 24 hours, while in the case of glass vessels, which have so far had the best insulating properties, 10 lost up to 12 percent in the same time went. ; Pa τ ε ν τ - A ν s ρ r υ c η: Metal vessel for storage and for.
