Abstract: A swage collar including a shank having a first end, a second end opposite the first end, and an outside diameter, a flange extending circumferentially from the first end of the shank and having a outer diameter, and a scalloped shoulder formed at a location where the first end of the shank transitions to the flange. When the swage collar is swaged, the shoulder is deformed from an undeformed state to a deformed state such that the shoulder is blended with the outside diameter of the shank and the outer diameter of the flange. When the shoulder is in its deformed state, it includes multiple curved portions each having a radius of curvature that visually indicates all around the outside diameter of the collar a complete swage of the collar. Knurling located on the outside diameter of the shank and proximate to the second end is deformable and provides a visual indication of the application of an installation tool.

Abstract: A method and apparatus for melting aluminum uses a dense metal salt of Rubidium, Cesium, or Strontium. The salt is melted by a stinger and then superheated by AC applied to electrodes immersed in the salt. Aluminum in contact with the salt melts and floats on the salt. In continuous scrap melting, inflows and outflows of aluminum are comparable and may be shielded by inert gas. The superheated salt may be purified and may be heated in a separate reservoir and pumped to and from another reservoir containing salt and/or metal. The salt may be used to supplement the heating of an existing furnace.

Abstract translation: 用于熔化铝的方法和装置使用铷，铯或锶的致密金属盐。 盐被托针熔化，然后通过AC过度加热浸在盐中的电极。 与盐接触的铝熔化并漂浮在盐上。 在连续的废料熔化中，铝的流入和流出是相当的并且可能被惰性气体遮蔽。 过热的盐可以被纯化，并且可以在单独的储存器中加热并且被泵送到另一个含有盐和/或金属的储存器中。 盐可用于补充现有炉的加热。

Abstract: A pin latch includes a guide block, a handle having a trigger, and a shear pin housed slidably within the guide block and connected to the handle. The shear pin includes a catch-pin engageable by the trigger, and is slidable between an engageable position and a disengageable position when the handle is moved from a closed position to an open position. Alternately, the pin latch includes a bracket connected to the shear pin and includes a catch-pin, and the handle is moveable to an intermediate position, such that a trigger is disengaged from the catch-pin and the shear pin engages a stop pin. A guide block spring acts on the stop pin to retain releasably the handle in its intermediate position. The guide block includes a finger and the shear pin includes a groove sized and shaped to receive the finger when the pin latch is in an unlatchable position.
