A thin, cured gel gasket is disclosed, including methods of making the thin gel gasket and the use of the thin gel gasket in an aircraft joint. In one embodiment, the thin gel gasket has no skeleton or other structure and is comprised of only a cured polyurethane gel and has a thickness of less than about 12 mill. It is manufactured using a release film that is adapted in a number of ways to make release from the gel prior to use easier. In one method of making and using the thin gel gasket. it is applied to a joint which is subject to compression, in one embodiment, a lap joint of an aircraft fuselage.

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element (30) having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

A bracket for retaining a disassembled rifle preferably includes a retention bracket and a pair of retractable spring pins. The retention bracket includes a base plate, a first yoke, a second yoke, a first lug and a second lug. The two lugs and the two yokes extend upward from a top of the base plate. A width of the lug slot is sized to receive a lug projection of an upper receiver half of a rifle. The two retractable spring pins are retained in the first and second yokes. The first and second lug holes are sized to receive a spring pin of a lower receiver half of a rifle. A second embodiment of the rifle bracket includes a retention bracket with yokes that extend from a side of a base plate and two lugs that extend from an opposing side of the base plate.

A de-coupling mechanism includes a link slidably received in a link aperture of a bracket. A pin is slidably received in a pin bore of the link and a receiving bore of the bracket. A first block is connected to the bracket and includes an initiator receiving passage in communication with the pin bore. An initiator is positioned in the initiator receiving passage and retained against a connecting passage edge and oppositely contacts an end face of a cap connected to the first block. A second block connected to the bracket includes a longitudinal channel having a channel diameter larger than a pin diameter so the pin is freely displaceable into the longitudinal channel. An end face of a retaining cap is connected to a second block end wall. The retaining cap includes a stepped portion having a step diameter smaller than the channel diameter and the pin diameter.

The clip includes a first engagement hook and a second engagement hook. The first engagement hook engages the body when the clip is in a normal fitting with the body. The second engagement hook prevents the clip from being disengaged from the body when the first engagement hook has been disengaged from the body. When the first engagement hook is disengaged from the body, a member is lifted away from surrounding members to such an extent as can be recognized by sight. Therefore, a state that the clip is not in the normal fitting state with the body is noticeable. Even if the clip is coupled to the body in the non-fitting state or half-fitting state, the second engagement hook prevents the clip from being disengaged from the body.
