A pipe joint assembly including a first pipe element, a second pipe element, a pair of segments, each segment defining a first end and a second end, each first end comprising a tongue and each second end comprising a groove, each groove defining a groove shoulder surface, the tongue of the one segment defining a tongue outer surface, the tongue outer surface of the tongue of the one segment angled at a non-zero angle relative to the groove shoulder surface in an assembled and untightened position, the tongue outer surface of the tongue positioned parallel and flush to the groove shoulder surface of the groove of the second segment in an assembled and tightened condition; and a pair of fasteners configured to deflect each segment around the first pipe element and the second pipe element in the assembled and tightened condition.

A method of connecting a first component and a second component with the aid of an auxiliary joining part, wherein the auxiliary joining part is formed from a pin and a plate. A position of intended fracture is present between the plate and the pin. The first component, the second component and the auxiliary joining part are brought into a stacked arrangement such that the plate contacts the first component and the pin projects away from the side of the plate remote from the first component. A force is exerted on the pin of the auxiliary joining part in the direction towards the stacked components which leads to a fracture at a position of intended fracture and the pin is used in order to pierce slugs from the stacked components. The end of the pin which is pressed through the second component, and/or a washer which is optionally provided there, is deformed in order to provide a form-locked connection to the second component or to a washer which is provided there. Furthermore, an auxiliary joining part is claimed.

An aircraft pipe coupling including a first pipe end and a second pipe end, and a locking washer disposed between the first pipe end and second pipe end. The locking washer including a first tab in engagement with the first pipe end, and a second tab in engagement with the second pipe end.

A pipe joint assembly including a first pipe element, a second pipe element, a pair of segments, each segment defining a first end and a second end, each first end comprising a tongue and each second end comprising a groove, each groove defining a groove shoulder surface, the tongue of the one segment defining a tongue outer surface, the tongue outer surface of the tongue of the one segment angled at a non-zero angle relative to the groove shoulder surface in an assembled and untightened position, the tongue outer surface of the tongue positioned parallel and flush to the groove shoulder surface of the groove of the second segment in an assembled and tightened condition; and a pair of fasteners configured to deflect each segment around the first pipe element and the second pipe element in the assembled and tightened condition.

A riveting device for setting a blind rivet element includes a mandrel, a first motor comprising a first operative connection to the mandrel, and a second motor comprising a second operative connection to the mandrel. The mandrel is configured to have a rotational movement be transmitted thereto to screw the mandrel into the blind rivet element, and to be retracted into the riveting device by a retraction movement to produce an at least partial plastic deformation of the blind rivet element. The first motor transmits the rotational movement to the mandrel via the first operative connection. The second motor transmits the retraction movement to the mandrel via the second operative connection.

A chair component includes a first chair member adapted to support a seated user, a second chair member movable between a first position, wherein the second chair member is substantially coplanar with the first chair member, and a second position, wherein the second chair member is substantially parallel with the first chair member, a cover member wrapped about at least a portion of the first chair member and at least a portion of the second chair member, and a single-piece drawstring operably coupled with the cover member to draw the cover member about the at least a portion of the first chair member and the at least a portion of the second chair member when the second chair member is in the first position.

A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at non-conventional connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the non-conventional connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the non-conventional connectors adjacent the front of the body includes a ferrule, a ferrule hub supporting the ferrule, and a split sleeve surrounding the ferrule.

A bolt includes a main-bolt head, a threaded shaft, and a deformable-bolt head component. The main-bolt head has a recess. The threaded shaft extends from the main-bolt head. The threaded shaft has an external thread wrapped therearound. The deformable-bolt head component has an outer flange and an interior threaded bore. The outer flange of the deformable-bolt head component is coupled to the main-bolt head such that a relief space is formed between the deformable-bolt head component and the recess.

A manufacturing method employing a robotic assembly system includes first and second fastener system components that are positioned by a robotic assembly on opposite sides of at least two structural pieces that are to be fastened together. The first system component includes a particular tool of a plurality of different types of tools, where the particular tool installs a particular fastener of a plurality of different types of fasteners. Each tool includes a block or base of magnetic material with a passageway opening for the fastener associated with the tool passing through the base. The robotic assembly positions the tool against one side of the structural pieces to be fastened, and positions an electromagnet assembly on the opposite side of the structural pieces. Activating the electromagnet assembly clamps the structural pieces together. With the fastener positioned in a hole through the structural pieces, the tool is activated to install the fastener between the structural pieces.
