    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: A fastening system including a fastener and a fastener installation tool. The fastener includes a pin member having an elongated shank portion with a threaded portion, a stop shoulder located at an end of the threaded portion, and a pull portion extending from the stop shoulder. The stop shoulder includes an outer rim and an inner annular wall. The inner annular wall and the inner face form an annular recess. The fastener installation tool includes a puller having a front face. The recess of the fastener is adapted to receive the front face of the fastener installation tool when the puller engages the pull portion of the pin member and facilitates alignment of teeth of the installation tool and pull grooves of the pin member.

    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.
