    • A barrel lock with a hollow cylindrical barrel having a perforated disk attached to one end thereof, and an elongated annular insert mounted within the barrel and extending from both ends of the barrel to provide loops at each end of the barrel. Preferably one end of the insert has a shoulder to engage the disk to prevent the annular insert from passing fully through the disk and the barrel. The barrel lock includes a spring clasp that is adapted to pass through the loop at the disk end of the barrel and also to pass through the perforation in the disk into the interior of the barrel. The spring clasp also engages and locks with the edges of the disk perforation when fully inserted.
    • 具有中空圆柱形筒体的桶形锁,其具有附接到其一端的多孔盘,以及安装在筒体内并从筒体两端延伸的细长环形插入件,以在筒体的每个端部处提供环。 优选地,插入件的一端具有肩部以接合盘以防止环形插入件完全通过盘和筒。 筒锁包括弹簧扣,其适于穿过桶的圆盘端处的环,并且还穿过盘中的穿孔进入筒的内部。 当完全插入时,弹簧扣也与磁盘穿孔的边缘接合并锁定。

    • Method and apparatus for making hollow links or rings and for making chain made from hollow links by receiving seamless wire which has an inner core and an exterior surface, for example, a gold alloy surface, making a perforation in the wire so as to expose the inner core at the perforation, and forming the wire into an open or closed link such that the perforation is located on a hidden portion of the link. The inner core may then be removed from the open or closed link by dissolving it in acid, wherein the acid contacts the inner core at the perforation thus allowing the acid to dissolve the inner core. A chain may be made by coupling each link with at least one preceding link to produce the chain.
    • 用于制造中空连杆或环的方法和装置,以及通过接收具有内芯和外表面(例如,金合金表面)的无缝线来制造由空心连接件制成的链条,从而在电线中穿孔以暴露 在穿孔处的内芯,并且将线形成为开放或闭合的连杆,使得穿孔位于连杆的隐藏部分上。 然后可以通过将内芯溶解在酸中而从打开或闭合的链节中除去内核,其中酸在穿孔处接触内核,从而允许酸溶解内核。 可以通过将每个链路与至少一个先前的链接相耦合来产生链,从而产生链。
