Abstract: A modular railing system supports a plurality of rails in vertically-spaced configuration. The railing system includes a plurality of baluster units arranged between rail sets to support the rails. The baluster units include a plurality of rail supports grouped into double barrel support pairs or single barrel support pairs. The baluster units may include a short section of kick rail, and longer sections of kick rail may extend between adjacent baluster units. Also, additional rails may be joined to the modular railing system using baluster extensions or extender bars. A stair rail adjuster may be used, particularly when railing staircases, to permit adjustment of the relative vertical height of one end of a rail. To attach rails and balusters to stair treads, a finished-stair-tread adapter may be used.

Abstract: An improved articulated pin joint for a track chain used on track laying work machines is provided. The articulated pin joint includes a plug positioned in a central cavity of a track pin. The plug includes an axial passage in which a needle can be inserted to inject grease into the central cavity.

Abstract: The end connector assembly (12) for a gas spring (44) enables the connector body to be connected with and disconnected from a ball (14) on the end of a ball stud (16) by relatively moving the connector body (26) and ball along a path generally parallel with the longitudinal axis of the gas spring (44) to which the connector body (26) is connected. The ball (14) enters the connector body (26) through an opening (32) in the body's front surface, that is, the surface generally perpendicular to the gas spring's longitudinal axis. A slot in the body's bottom surface, that is, the surface facing the ball (14), accommodates the shaft portion (22) of the ball stud (16), adjacent the ball (14), as the ball moves into or out of the connector body (26) through the opening (32).

Abstract: A self locking fastener system is disclosed for light-weight ballistic resistant applications. The fastener system includes a ballistic resistant cap nut with an integral shoulder. The shoulder is formed onto the mating surface of the cap nut and is keyed to lock with a cut-out in a structural member to which the fastener system is secured. In a commercial aircraft, the cap nut is located on the passenger cabin side of the ballistic resistant flight deck door and prevents tampering therewith that might otherwise lead to disassembly or damage to the fastener system and degrade the ballistic resistance of the door assembly. Thus provided, the fastener system is resistant to removal by manipulation of the cap nut as well as damage from ballistic projectiles. The shoulder of the cap nut increases the shear area of the fastener along the plane of the mating surface thereby enhancing the fastener's resistance to shear loading. The cap nut is constructed of titanium or stainless steel.

Abstract: A landscape timber anchoring system uses a series of posts that each having openings that receive an end of a landscape timber. Pairs of posts are located in spaced apart fashion and the ends of the timbers are received within respective openings on the posts. Additional openings can be located above the initial openings to receive additional timbers in stacked fashion. Further openings can be disposed on the posts in an orientation that is different relative to the orientation of the first openings to receive an end of additional timbers with the opposing end of such timbers received within appropriate openings located on additional posts. Planks can be received within slits located on the posts in lieu of or in addition to the timbers.

Abstract: Ball-and-socket joint includes a joint housing (1) and a ball head (2) with a ball pivot (3). A bearing shell (4) is disposed between the ball head (2), the joint housing (1), and a housing cover (5). A compressive force is produced between the housing cover (5) and at least a portion of the bearing shell (4). The compressive force acts in an axial direction of the ball pivot (3). The compressive force permanently acts on the portion of the bearing shell (4) and presses the portion of the bearing shell (4) into a gap between the ball head (2) and the joint housing (1).

Abstract: A barrier such as a fence is formed by welding conductive upright members to conductive U-shaped rails by a projection resistance welding process. The rail includes at least one weld-forming region which projects within the rail channel, and may be formed wither as a ridge, or as a longitudinally spaced series of nipple-shaped projections. The upright member is transversely positioned within the rail channel in contact with the weld-forming region. A welding current transmitted between the upright member and the rail causes the weld-forming region to at least partially melt and form a weld within the rail channel.

Abstract: The invention relates to a sealing connecting element, a sealing end piece and a seal. In practice different seals are known which are produced as three dimensional structures and then given to the customer. The production, wherein profile strips are ready-made by cutting and adhesion to form the three dimensional structures or wherein the three dimensional structure is obtained by means of corner injection molding, is very costly. In order to simplify the production of seals, it is provided in accordance with the invention that sealing connecting elements and/or sealing end pieces are to be produced as separate molded parts made of a thermoplastic elastomer and these molded parts to be connected, shortly before the installation of a seal, to sealing profile strips to form a complete seal.
