    • A metal truss assembly comprises a plurality of C-shape structural members including at least one chord member and two or more adjacent web members, each structural member having a base and two opposing flanges. The at least one C-shape chord member has flanges extending from each side of the base with one flange having cutouts to receive two C-shape web members with a part of said flange of said chord member in place between said cutouts. Each said C-shape web member is placed into one of the cutouts in said flange to intersect the at least one chord member with the bases of the two C-shape web members adjacent the base of the at least one chord member.
    • 金属桁架组件包括多个C形结构构件,其包括至少一个弦构件和两个或更多个相邻的腹板构件,每个结构构件具有底座和两个相对的凸缘。 所述至少一个C形弦构件具有从所述基座的每一侧延伸的凸缘,其中一个凸缘具有切口以接收两个C形腹板构件,所述弦构件的所述凸缘的一部分在所述切口之间就位。 每个所述C形腹板构件被放置在所述凸缘中的一个切口中,以与所述至少一个弦构件相交,所述两个C形腹板构件的基部邻近所述至少一个弦构件的底部。

    • An auto-nucleating device includes a tube containing a crystalline cholesterol matrix. The ends of the tube are closed by a membrane that is impermeable to the cholesterol but permeable to liquids contained in a cryopreservation vessel. The auto-nucleating device provides a site for ice nucleation during freezing of the liquid within the vessel. One such cryopreservation vessel is a flexible vial having a closed port at one adapted to be pierced by a needle to withdraw the liquid within, and an opposite end that is initially open to receive the liquid. Another vessel includes an adaptor mounted to liquid container with a tubular branch closed by a needle septum and another tubular branch provided with a barbed fitting for engaging a flexible tube that terminates in a needle septum. In another embodiment, the vessel includes an inlet and vent branch at the top of the container and an outlet septum at a bottom opening.
    • 自动成核装置包括含有结晶胆固醇基质的管。 管的端部由对胆固醇不渗透但对包含在冷冻保存容器中的液体可渗透的膜封闭。 自动成核装置在容器内的液体冷冻期间提供冰成核的部位。 一个这样的冷冻保存容器是柔性小瓶,其具有适于被针刺入以将其中的液体抽出的封闭端口,以及初始打开以接收液体的相对端。 另一个容器包括一个安装到液体容器上的适配器,其中一个管状分支被一个针隔膜封闭,另一个管状分支设有一个带倒钩的配件,用于接合终止于针间隔的柔性管。 在另一个实施例中,容器在容器的顶部包括入口和通气分支以及底部开口处的出口隔膜。
