Abstract: A fastener element (2) has first and second body portions (4, 6) that are mechanically interlocked. The first body portion (4) has an integral outer end disk (20) with a flat outer radial surface (26). The second body portion (6) has circumferentially spaced legs (48) that extend along chordal surfaces (28) on the first body portion (4) and terminate axially inwardly of the disk (20). The legs (48) interlock with projections (30) on the surfaces (28). The legs are tapered to direct binding material from a fill opening into flow passageways and then toward a vent opening during a molding-in procedure to install the element (2) in a structure.

Abstract: A fastener element (2) has first and second body portions (10, 34) that are mechanically interlocked. The portions (10, 34) define an axial opening (12, 14) that opens onto a radial end surface (25) of the body (10, 34). One portion (10) has a radial shoulder (32) facing away from the end surface (25) and defining an increased width inner portion (14) of the axial opening. A floating member (56) positioned in the axial opening (12, 14) has an outer end (66) adjacent to the end surface (25) and an opposite inner end with a head (60) that is received in the inner portion (14) and abuts the shoulder (32) to transmit axial loads created by engagement of the member (56) by a fastener. Flow passageways (18) are formed around the element (2), which is molded in a core cavity (88) in a honeycomb panel (80) using potting material (96) .

Abstract: A fastener element (40) has a first member (41) including an outer end disk (42) and two radially spaced, axially extending flat stem legs (53). A second stem-forming member (62) has a T-shaped axial opening (64, 66) and is mechanically interlocked with the legs (53). A floating member (84) is positioned in the opening (64, 66) and has an internally threaded opening (90) which is aligned with a center opening (44) in the disk (42). The T-shaped floating member (84) is prevented from rotating in the opening (64, 66) but is allowed to move radially to automatically adjust for misalignments between a structure in which the element (40) is installed and an object to be connected thereto by means of a screw introduced into the threaded opening (90) through the disk opening (44). When the element (40) is to be installed in a structure by a potting material (34), the stem (53, 62) preferably has flow control disks ( 72, 74) and flat chord surfaces (54).

Abstract: A fastener element is ejection molded from an engineering resin of a type that will bond to potting resin used for securing the fastener element within a cavity formed within a panel of composite material. The fastener element includes flow control disks spaced apart along a stem portion between end portions. Flats are formed on opposite sides of the flow control disks, below fill and vent openings. Resin introduced into the fill hole travels down to the bottom of the cavity and around the fastener element and fills the cavity from the bottom up, so that the presence of resin at the vent opening will indicate that the cavity has been filled with resin and does not include an airspace or void.

Abstract: A plurality of nut inserts (40) and an elongated channel (10) form a gang nut assembly. The channel (10) is formed to include a plurality of longitudinally spaced apart nut receiving openings (28). These openings (28) are partially defined by opposed recesses (24, 26) in flanges (18, 20). The nut insert (40) has a base length (LB) which is smaller than the length (Y) of the opening (28). It also has end walls (44, 46) which diverge apart as they extend upwardly from a base (42). The base (42) is put into registry with the opening (28) and the nut insert (40), is pushed upon, to force it through the opening (28). The sloping outer surfaces of the end walls (44, 46) contact flange edges (30, 32, 34, 36). This causes the end walls (44, 46) to spring together, in response to the push on the nut insert (40), allowing the nut insert (40) to pass through the opening (28).

Abstract: First (12) and second (42,62) body portions are each attached to a structural member. The first body portion (12) includes trunnions (18) that are slidably received in corresponding channels in the second body portion (42,62). The second body portion (42,62) includes a base member (62) and a pivot member (42), which cooperate to form the channels. The pivot member (42) has an open position and a closed position. A spring (82) biases the pivot member (42) in its closed position. A lever (44) moves the pivot member (42) against the force of the spring (82) into its open position. When the pivot member (42) is in its closed position, it blocks portions of the channels, thereby locking the trunnions (18) into one of two lock positions in the channels. When the pivot member (42) is in its open position, the trunnions (18) may slide in the channels from one lock position to another or out of the channels to disengage the two body portions.

Abstract: A horizontally positioned restraining bar which has at each end a spring biased guiding member. The bar is located in the access opening of a magazine compartment, bookcase, storage bin or the like which is provided with vertically mounted rails at the vertical sides of the access opening. The bar is slidingly arranged by the guiding members in the rails and positioned at a predetermined horizontal level within the access opening for restraining objects from falling out of the compartment. By manually raising the bar, an object can be retrieved from the compartment after which the bar automatically will return to its previous restraining level by gravity. The apparatus is particularly designed for use on airplanes, moving vehicles, etc. and is provided with features to assure a rattle free and noiseless operation as well as quick installation and removal features.

Abstract: The latching apparatus has an external housing which contains a recess, an internal activating mechanism and a biased locking bolt for engagement with an associated striker plate. The operation of the latch is accomplished by inserting the hand into the recess and sliding a therein positioned handle cup. The movement of the cup causes, inside of the activating mechanism, the spreading of two levers which are geared to one another and are connected to the spring biased locking bolt. The levers will upon movement make contact with a pivot point and the resulted leverage action will pull the bolt to a retracted or unlatched position. Release of the handle cup automatically reverses the operation and moves the bolt in the latching position.
