    Abstract: A cryostat arrangement for keeping liquid helium comprising an outer shell (2), a helium container (6) installed therein and a neck pipe (4) extending from the helium container to the outer shell whose upper warm end is connected to the outer shell and whose lower cold end is connected to the helium container, wherein the outer shell, the helium container and the neck pipe define an evacuated space (13) containing a radiation shield (15) surrounding the helium container and being connected at a coupling to the neck pipe in a heat-conducting fashion, wherein a refrigerator is installed in the neck pipe having a cold finger (5a) which consists of at least one pipe and projects into the neck pipe, is characterized in that at least one pipe of the cold finger is surrounded by at least one separating body (3a) which divides the neck pipe into two partial volumes (8a and 9a) which are connected to one another through a lower opening (10a) and an upper opening (7a). A cryostat arrangement of this type with active cooling through refrigerators shows considerable improvements over conventional cryostats with respect to thermal properties. In particular, it is possible to completely stop consumption of liquid helium.

    Abstract: The tank is a modified form of the lobed tank described in British Pat. No. 1522609, whereby the tank ends are of simpler constructional form. Thus, the tank comprises, top, bottom and two opposed side walls (1 to 4) each consisting of parallel, part-cylindrical lobes (11) which are connected and tied together by tie-plates (13, 14) and elongated armed insert elements (16, 17 and 17a). The invention is characterized in that each one of said other two opposed side walls (5, 6) comprises at least two part-lobes (11c) which present straight edges to which the common straight end edges of a series of two-way corner transition (12c) and part-transition (12d) pieces are joined, and in that the end of each part-lobe (11c) has a respective part-transition piece (12d) joined thereto to present a curved edge to which a part-spherical three-way corner (12b) can be joined to close-off the side wall (5 or 6). Preferably, the transition and part-transition pieces are joined together via elongate curved insert elements (12e) in which there is a smooth transition from being of generally "Y" cross-section at one end to "T" cross-section at the other end.

    Abstract translation: 坦克是英国Pat描述的裂缝坦克的修改形式。 其中罐端部具有更简单的结构形式。 因此,罐包括顶部,底部和两个相对的侧壁(1至4),每个侧壁由平行的部分圆柱形突出部分(11)组成,它们通过连接板(13,14)连接并连接在一起, 元件(16,17和17a)。 本发明的特征在于,所述另外两个相对的侧壁(5,6)中的每一个包括至少两个部分凸角(11c),其呈现直边,一系列双向角转变的共同直边缘 (12c)和部分转变(12d)片接合,并且每个部分叶片(11c)的端部具有连接到其上的相应的部分过渡片(12d),以呈现弯曲的边缘,部分球形 三通角(12b)可以接合以关闭侧壁(5或6)。 优选地,过渡部分过渡片通过细长的弯曲插入元件(12e)连接在一起,其中从一端的“Y”横截面平滑过渡到另一端的“T”横截面 结束。
