An apparatus for fastening a pair of gas vessels includes: a plurality of first units formed of a composite material, spaced apart from each other in parallel with each other in a length direction of the gas vessel, and having the pair of gas vessels seated on both sides thereof; a second unit formed of a composite material and extending in the length direction of the gas vessels to integrally connect the plurality of first units; and a plurality of fastening units each of which extending along a circumference of the gas vessels to enclose the gas vessels seated on the first units and having both ends connected to the first units.

The invention relates to a method for applying a joint (2, 102) onto a plate (3), in particular a plate having shape defects. An edge of interest is defined on a portion of the plate (3) onto which the joint (2, 102) is intended to be applied. The plate (3) is then placed on a tool (4, 104) comprising a supporting element (5, 105) made of solid material and a supporting element (6, 106) made of flexible material, in such a way that the edge of interest rests on a portion of the supporting element made of flexible material. While the joint is applied onto the edge of interest, the plate is maintained in a predetermined reference position and the element made of flexible material is pushed against the plate, perpendicularly to an outer surface of the element made of flexible material, the outer surface being opposite to the surface on which the edge of interest rests.

Methods and apparatus for positioning a structure on a polymer layer are described. A method may involve forming a first polymer layer. The method may further involve positioning, by an apparatus, a structure on the first polymer layer, where the apparatus comprises a rod having a first end that supports the structure as the structure is being positioned and a plunger located around the first end of the rod that presses the structure onto the first polymer layer as the structure is being positioned. And the method may involve forming a second polymer layer over the first polymer layer and the structure, where the first polymer layer defines a first side of a body-mountable device and the second polymer layer defines a second side of the body-mountable device opposite the first side.

The present invention relates to a method of applying a film to a body. In this respect, a film is first applied to and positioned at a transfer mold and the body to be film coated is introduced into the transfer mold to which the film to be attached is applied or the transfer mold to which the film to be attached is applied is introduced into the body to be film coated so that the film is located between the body and the transfer mold. In the further course, a vacuum is applied in a region between the body and the film and/or an excess pressure is applied in a region between the transfer mold and the film so that the film moves from the transfer mold onto the body. A particularly simple method that is fast to be carried out is thereby provided for applying a film to a surface.

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.
