Definitions

  • the inner wall forms a vessel containing the equipment which must operate at low temperature.
  • the cooling of this vessel is ensured either by suitable heat-exchangers or by providing a liquefied gas such as hydrogen or helium, for instance.
  • Liquid helium for example, is rather lightweight so that, it put in the vessel, no special features are required for the supporting of the latter.
  • the vacuum concentric vessels are held one to the other by the neck of the container, which allows the filling with liquified gas and as long as no heavy equipment is present in the vessel, the supporting at filling neck level is adequate for holding the inner vessel.
  • the present invention relates to a supporting arrangement with a high performance thermal insulation while avoiding the above-mentioned drawbacks.
  • the supporting arrangement according to the present invention is remarkable in particular by the fact that it comprises, for the transmission of rest or thrust forces, at least one, component working in tension.
  • the support comprises two rigid components of generally long shape, arranged parallel one to the other and overlapping on a fraction of their lengths, the ends of said rigid components making up the rest points of the support while the inner ends of said rigid elements are connected by the above-mentioned component working in tension.
  • the arrangement according to the invention is advantageous because the path of the heat losses is via a component working in tension. It is possible to select a very small cross-section component since its cross-section area is designed to meet strictly the force necessary for carrying in tension the load applied to it. For the sustainers which include. only components working in compression, the dimension of the elements must not only correspond to the load applied directly but it must also be adequate to resist buckling. One is then led to use much larger crosssection areas than those which would be sufiicient to carry the loads in tension and these cross-sections do not allow an adequate insulation.
  • the above-mentioned component working in tension is made of tension resistant and heat insulating fibres, such as a synthetic fibre cable.
  • These fibres may be advantageously made of superpolyamide, such as those with trademarks Dacron or Tergal.
  • This arrangement provides a good thermal insulation and is made possible by the fact that the component works in tension.
  • the component Working in tension is made by an endless cable arranged as a loop and the rigid elements associated with this component comprise means for simply fastening said cable.
  • an endless cable provides a safe and simple attachment.
  • FIGURE 1 is a vertical section, along the axis, of an arrangement according to the invention, located between two concentric Walls of an insulating multi-wall container;
  • FIGURE/2 is a section along line HII of FIGURE 1;
  • FIGURE 3 is a view comparable to that of FIGURE 1 V of another embodiment.
  • FIGURE 4 is another view comparable to that of FIGURE 1 of another embodiment.
  • the isothermal container comprises two, and possibly more, concentric parallel walls 10-11 between which is a high vacuum for insuring thermal insulation.
  • a first support member 12, which may comprise a tube, integral with the wall 10 is provided with four slots 13, 14, 15, 16.
  • the support member 12 may be made of stainless steel or plastics such as, for example, stratified polyester fitted, and stuck onto a metallic shoulder.
  • a rod 18 connected with the wall 11 is introduced into the support member 12.
  • the rod 18 is held onto the wall 11 through a stub 19, a threaded end of the rod 18 being screwed up into said stub.
  • This threaded connection provides a means to set the tension of the suspension and the relative positioning of the two walls 10 and 11;
  • a ring joint 21 enables a temporary sealing to be achieved during the setting operations; once the latter .are over, the screw 18 :and the stub 19 are tightened and the sealing is ensured, for instance, by a lip fusion argon Weld 22.
  • the rod 18 may be made of two parts, a metallic one .for the setting and sealing area, i.e. the bottom .end, and a pa 23,.made of an insulating material such as polyester, which may be fitted and/ or stuck onto the metallic part.
  • the rod 18 and the support member 12 are connected by a flexible cable 25 placed on the tube via slots 13-15 and resting on the rod 18 via a cap 26 provided, for this purpose, with two grooves 27 and 28.
  • a small plate 29, held for instance by a screw 30, covers the upper part of the cap 26.
  • the cap 26 is laid on the rod 18 so that it may oscillate a little in order to accommodate the differences in tension between the different sides of the cable 25.
  • it may comprise a shape which matches the shape of the inner end of the rod 18, for example, as a conical shaped end 32.
  • the arrangement according to the invention has a small bulk: it may be housed within a relatively small solid angle and makes easy the use of insulator with anti-infrared shield, which is not the case for strap or oblique tie-rod suspensions. Consequently, the volume where heat losses may take place is particularly small.
  • FIGURE 3 shows an embodiment in which the insulation is still improved.
  • an intermediate member or tube 53 is provided for.
  • the rod 50 and the intermediate tube 53 are connected by a first flexible cable 55, fitted on the tube 53 as above, and on the rod 50 through a cap 56 of the same sort as the cap 26 of FIGURE 1.
  • the tube 53 itself is connected to the tube 51 by a second insulating cable 57 fitted also in the same manner on the tube 51 and fitted on the tube 53 through a cap 58 of the same kind as the cap 26 of FIGURE I, placed on the upper end of the tube 53.
  • a support offers an increased resistance to the flow of which has a lower heat flux, but the transversal stability, may be used together with arrangements in accordance with the embodiment of FIGURE 1.
  • an intermediate element 63 comprising a conical part, has been provided for between the rod 61 and the outer tube 62.
  • Such a layout might also be used for the outer tube, in the embodiment of FIGURE 1, as well as in that of FIGURE 3.
  • the supports according to the invention may be placed in the lower part of the vessels, in order to carry the vertical loads; they may also be placed on the side walls so as to hold the vessel against the transversal forces. They can also be provided for at the upper part, if necessary.
  • first support member mounted on the surface of one of said vessels, said first support member extending toward the surface of the other vessel in the space between said vessels,
  • means including a flexible cable formed of a material of low thermal conductivity mechanically connecting the free end portion of said first support member to the free end portion of said second support member partially within said first support member with said connecting means under tension and said first support member and said second support member under compression.
  • An insulating support element for supporting and thermally isolating wall members of low temperature storage containers comprising at least an inner vessel and an outer vessel surrounding said inner vessel in spaced relation to said inner vessel, in combination, comprising:
  • first support member mounted on the surface of one of said vessels, said first support member extending toward the surface of the other vessel in the space between said vessels,
  • connecting means for mechanically interconnecting said first support member, said second support member and said intermediate member
  • said connecting means including a first flexible cable mechanically connecting said end of said intermediate member with the free end of said first support member,
  • said second support member being partially inserted within said intermediate member, so that said first cable and said second cable are in tension and said first support member and said second support member are in compression
  • said first cable and said second cable having low thermal conductivity.
  • An insulating support element further including at least one intermediate member, said intermediate member having a first end and a second end positioned to be in nested stacked relationship with said support members, the first end of said intermediate member being mechanically connected by flexible cables to the free end of said first support member, and the second end of said intermediate member being mechanically connected by flexible cables to the free end of said second support member.
  • An insulating support element for supporting and age containers comprising at least an inner vessel and an outer vessel surrounding said inner vessel in spaced relation to said inner vessel in combination, comprising:
  • first support member mounted on the surface of one of said vessels, said first support member extending toward the surface of the other vessel in the space between said vessels,
  • connecting means including a flexible cable formed of a material of low thermal conductivity mechanically connecting the free end portion of said first support member to the free end portion of said second support member within said first support member with said connecting means under tension and said first support member and said second support member under compression,
  • said second support member includes a shaft having adjustment means for varying the tension on said connecting means
  • said adjustment means comprises a threaded connection outer vessel, and said free end of said first support member includes a plurality of slots positioned around its periphery for engaging said flexible cable.
