Provided is a conductive polymer dispersion, including: a conductive composite containing a π-conjugated conductive polymer and a polyanion; a vinyl versatate polymer; and a dispersion medium.

A fluid chamber for a shoe may be formed using pressure channels in a forming mold, eliminating the need to insert a nozzle or needles into the chamber for inflation. A fluid chamber so formed may have a smaller seal area than a chamber formed using an inflation needle, making the chamber more visually pleasing. Apparatus and methods for forming a fluid chamber in this fashion are also disclosed.

The present invention provides enthalpy exchanger elements (E, E′, PR, PF) and enthalpy exchangers comprising such elements. Furthermore, the invention discloses a method for producing such enthalpy exchanger elements and enthalpy exchangers, comprising the steps of a) providing an air-permeable sheet element (1); b) laminating at least one side (1a, 1b) of the sheet element (1) with a thin polymer film (3, 4) with water vapor transmission characteristics; and c) forming the laminated sheet element (1) into a desired shape exhibiting a three-dimensional corrugation pattern (5, 5, . . . ).

A method of forming a vacuum insulated structure includes providing a structural envelope an insulating cavity defined within the structural envelope. An expanding device is attached to opposing outer walls of the structural envelope and the interior cavity is expanded by pulling the opposing outer walls away from one another to define an expanded state. An insulating material is disposed within the insulating cavity to occupy substantially all of the insulating cavity in the expanded state. Gas is expressed from the insulating cavity to collapse the structural envelope to a final state and a final interior volume that is less than the expanded interior volume. The final state of the structural envelope defines a densified state of the insulating material within the insulating cavity. The vacuum port is then closed to hermetically seal the insulating cavity.

Respiratory masks made of thermoformed EVA foam are provided. A mask can include a seal that contacts a user's face in use and a housing permanently joined to the seal. Both the seal and housing can be made of EVA foam. The seal and housing can be made of EVA foam having different densities. The mask can further include a frame removably or permanently coupled the housing. Headgear can be coupled to the frame and can couple the mask to the user's face in use.

In order to achieve the above-mentioned object, according to an embodiment of the present technology, there is provided a structure including a decorative portion and a member. The decorative portion includes a single-layered metal layer that includes fine cracks and varies in addition concentration of a predetermined element in a thickness direction of the metal layer. The member includes a decorated region to which the decorative portion is bonded.

A method of forming a fibre article, comprising: providing a former having a contoured forming surface; locating a fibre preform between a first diaphragm and a second diaphragm, the second diaphragm being offset from the forming surface; drawing a vacuum between the first and second diaphragms so as to hold the preform captive between the diaphragms; displacing the second diaphragm towards the former so as to bring the second diaphragm into partial contact with the former; drawing a vacuum between the second diaphragm and the former so as to bring at least a part of the second diaphragm adjoining the preform into conformity with the forming surface; and setting the preform in its configuration; wherein: the fibre preform comprises one or more substantially inextensible fibres extending linearly in a first direction; the forming surface comprises a concavity and prominences on either side of the concavity; and the step of bringing the second diaphragm into partial contact with the former comprises bringing the second diaphragm into contact with the prominences whilst the second diaphragm does not fully contact the concavity and with the substantially inextensible fibres extending from one of the prominences to the other.
