PAUL HEYLANDT, 0F BERLIN-SUDENDE, GERMANY.
METAL VESSEL FOR STORING AND CONVEYING LIQUEFIED GASES.
Application filed January 3, 1921. SerialNo. 434 831."
(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. 1., 1313.)
To all whom'z't may concern:
Be it known that 1, PAUL HEYLANDT, a citizen of the German Republic, residing at Berlin-Sudende, Germany, have invented certain new and useful Improvements in Metal Vessels for Storin and Conveying Liquefied Gases (for whic 1'1 have filed applications in Austria under date of March 23, 1915, and Luxemburg under 'date of March 28, 1915), of which the following is a specification.
The invention relates in general to means for storing and conveying liquefied gases of all kinds, particularly liquid am The object of the invention is to isolate the vessels used for this purpose from the effects of their surroundings to such an extent that the least possible loss of gas'takes place.
The vessel according to the invention differs from the knownmetal vessels for storing and conveying liquefied gases (which consist of an inner vessel suspended freely by a long outflow pipe in a similarly shaped outer vessel) in that the exchanging of heat or thermal leak is considerably reduced by the neck that was used for suspending the inner vessel being replaced by a long fine wire, or by a long fine tube whose cross section is too small to enable it to be used for the filling in and pouring out of the liquefied gas and, is large enough to allow only the gases to escape that are formed by unavoiolable evaporation. Another distinguishing feature of the novel Vessel is that the inner vessel or globe is held in place by stays or a plurality of suspension members consisting of fine wires which prevent the inner globe from coming in contact with the outer globe and thus obviate the warming of the contents of the inner globe that would thus arise, and effect a considerable decrease of the amount of gas that is unavoidably lost.
The lateral holding members used in the double-walled glass vessels of the 'Weinhold and Dewar type also involve the disadvantage of a too considerable thermal leak.
In other known metal vessels of the general type contemplated herein the hollow supports arranged between the inner and outer vessels serve as exits for the gases formed and are cooled by them so that the result obtained is similar to the object of But as far as the bulk or mass of the said hollow supports is concerned the are very d sadvantageous in comparison with the fine wires used in accordance with this invention, and which are subjected to tensile stresses only. By using wires of this kind the amount of gas lost is reduced to a minimum.
Some constructional forms of vessels designed in accordance with the invention are shown in the drawingin which Fig. 1 is a vertical section of a vessel or fiaskin whichthe inner chamber or globe 1s suspended by a thin wire,
Fig. 2 shows a flask in which radial fine w1re ties are used for holding the, inner vessel in addition to the suspension member, 7
lateral tubes are brought into a small com pass by making them spiral-shaped, and
Fig. 6 is a sectional view of a modified form of the flask shown in Fig. 2. In Fig. 1 the inner vessel or globe a is providedat c with a chamber or some suitable accommodation for a gas-absorbing substance, preferably carbonate of magnesium, which serves to maintains. high vacuum in the space between the outer vessel or shell 5 and the inner vessel a. b is bulged outwardly or dome-shaped at the top, the dome-shaped space being adapted to receive a spiral-shaped inflow pipe a? for the liquefied gas to be stored in a, whilst the inner vessel has a long downwardly extende5 ing cavity e which serves to lengthen the distance from the bottom end of a fine metal suspension wire 7 of great tensile strength to the outer vessel from which the inner vessel with its liquid contents depends. It will be obvious that the great length of the supportingwire f and that of the still longer pipe 0? considerably impede the lineal conduction of heat.
In Fig. 2 a flask is shown in which the inner vessel a is held in the shell 5 by suitable ties d, f, so that, contrary to the arrangements shown in Figs. 1 and 3, the insimilar 75 The shell as jects so as to surround the pouring in and out of the liqui andthe fine shaped protuberances of the outer shell '6.
In the modified form shown in Fig. 6, the same result is accomplished by means of the centering or stay members i attached to the inner wall of the shell I) at diametrically opposite points and extendin into recess forming portions of the vesse a.
The number of wires or ties used may be increased or decreased at will.
In the flask shown in Fig. '3 the outer vessel b is' provided with two ateral extensions 6', 6 into which the evacuated space propi e d for the tube d for discharging the evaporated gas.
In order to increase to the greatest possible extent the length of the thermal conductors formed by the tubes or wires between the inner and outer vessels, the flasks can be made cylindrical in shape as shown in Fig. 5. The inner essel a that contains the liquid 9' is held in acentral position by a wire f that is attached to the bottom of a deep cavity e, and the two tubes at, d are for the purpose of pouring the liquid in or' out and for the exit of the evaporated gases.
In the constructional form shown in Fig, 5 the exigencies of limited space are considered, the vessel being made to contain as much liquid as possible while taking up the smallest possible space. To this end 'the tubes (1, d between the inner and outer vessel are made spiral-shaped or helical. The inner vessel is held up by the wire f only and the long pi es are for pouring the liquid in and out. if course the space between the inner and outer vessel could be made much wider, especially if this space is not evacuated but merely filled with a poor con-. ductor of heat such as sheeps wool, eider down or the like. a
In the case of flasks provided with a vacuum for the purposes of insulation, the vacuum need not be produced by a vacuum pump, but so large a quantity of the afore said gas-absorbing substance indicated in the drawing can be inserted that on the liquefied gas being poured in, an adequate vacuum is formed automatically. It is already known that vessels in which the in sulation is formed by a vacuum must contain a gas-absorbing substance on account of the porosit of the metal.
From the oregoing 1t w1ll be observed that in all forms of the flask herein shown,
"flask-formin one, or both,'of the flask formingmembers, is provided with a hollow ortion forming a recess in communication with the space between said members and that the connecting member is attached at one end to the inner end wall of the recess so formed and at its other end to the other member, or to the recess formed in said other member, whereby the suspending or connecting member will be of considerabl greater length than was heretofore possib e. 4
