A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

Apparatus configured to enable the staking of an interfacing part to a base is provided. The apparatus includes a retainer configured to convey a stake and the interfacing part to the base. The apparatus is further configured to provide a heat and/or vibration to effect the simultaneous attachment of the stake to the base and the interfacing part to the base.

Apparatus and methods for installing composite rivets are disclosed. One disclosed method comprises: inserting a composite rivet blank comprising a composite material into a hole in a part; heating the composite rivet blank using Joule heating while the composite rivet blank is in the hole; and then finishing the composite rivet blank.

A method for the connection of a first component to a second component includes providing a first component which has a projection with an undercut, and providing a second component which has a cavity. The method also includes introducing a sealing and/or connecting material into the cavity of the second component, and joining the first component and the second component together to form a component arrangement. The projection of the first component projects, in the joined state, into the cavity of the second component.

A method for joining a first component and a second component. The method includes forming a first bond between the first component and the second component by providing a plurality of projections on the first component and embedding the plurality of projections in the second component; creating a fastener hole which passes through the first component and the second component and which encompasses at least one of the projections; and forming a second bond between the first component and the second component by installing a fastener in the fastener hole.

The present invention is directed to the use of an improved hydrocarbon adsorption system for the treatment of evaporative emissions from a motor vehicle. More specifically, the system includes one or more hydrocarbon adsorption elements being housed within a frame, the frame being permanently affixed within the air intake housing of engine.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

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.

A microfluidic flow cell for carrying out an analysis, having a substrate of synthetic material, which has cavities for the formation of channel structures and chambers, wherein the cavities are closed on one side of the substrate by a film adhesively bonded or welded to the substrate, and having a housing component that is produced with a hard and a soft component, which, on the side of the substrate facing away from the film, is connected to the substrate, completing functional sections respectively fulfilling the function of the flow cell. The housing component is formed as a multifunctional part completing more than two functional sections.
