Abstract: A latch having body with a hook, a handle attached pivotally to the body, and a series of links that facilitate opening and closing the handle. The links include a pair of front links, a pair of back links, and a middle link. The middle link connects the front links and the back links at one end of the middle link and with slots in the front link. The other end of the middle link pivots with the handle via a rivet. The middle link acts as an extended arm to drive the front links and back links for opening and closing the latch. A handle spring provides a means to pop-open the handle. A pair of link covers retains the front links and the back links on the body.

Abstract: New 6xxx aluminum alloy sheet products and methods of making the same are disclosed. The new methods may include preparing a 6xxx aluminum alloy sheet product for solution heat treatment, solution heat treating and then quenching the 6xxx aluminum alloy sheet product, and then exposing the 6xxx aluminum alloy sheet product to a treatment temperature of from 30° C. to 60° C. for 0.2 to 300 seconds. After the exposing step, the 6xxx aluminum alloy sheet product may be coiled and then placed in an ambient environment. Due to the post-quench heating and subsequent exposure to ambient, a preselected amount of Newtonian cooling may be induced, thereby creating a unique and consistent microstructure within the 6xxx aluminum alloy sheet products.

Abstract: A pin member for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. The pin member can be fully coated with a coating. A conformable seal element is attached to the pin member, which is adapted to fill the microscopic voids between the bearing surface of the head of the pin member and the surrounding structure under the axial load exerted by the fastener during installation. The seal element can be separate and distinct from the pin member. The seal element can be attached to the pin member for the sake of convenience, but the seal element can deform independently of the pin member and the surrounding structure in response to the forces exerted by the fastener.
