A method for producing an expanded metal, the method including producing a sheet of the expanded sheet metal by introducing openings through one expansion blade wherein all the openings are configured as diamond shaped loops without a material loss and defined by a loop width, a loop length and a loop shape; and forming the diamond shaped loops respectively by four linear bars that are defined by a bar width and a bar thickness wherein two of the four linear bars are respectively connected at four nodes; arranging plural of the diamond shaped loops in columns adjacent to one another and in rows adjacent to one another; and forming first columns of first diamond shaped loops different from second columns of diamond shaped second loops in a loop width or in a loop length respectively measured from a node center to a node center.

A cold worked stainless steel bezel for a portable electronic device is provided. The bezel is secured flush to a housing to form part of the case of the portable electronic device. A brace that includes a slot for receiving a wall extending from the bezel is fixed to the housing. When the bezel engages the housing, the wall of the bezel is inserted in the slot of the brace and releasably held by a spring that engages both the brace and the wall. The bezel can be released by disengaging the spring, (e.g., using a special tool or a magnetic field). Because the bezel is manufactured from cold worked stainless steel, it is hard and resistant to impacts. Cold worked steel also facilitates manufacturing within design constraints and tolerances, and requires very little machining after manufacturing to comply with those constraints.

A reinforcing, baffling, or sealing device for a vehicle structure, the device comprising a carrier, an expandable material applied to the carrier, and openings formed in the carrier. The expandable material is formed of a heat activated material having foamable characteristics. The openings are formed in a repetitive pattern and perpendicular to a horizontal axis of the device. The device is stretched along the horizontal axis.

A cathode-side gas flow path of a cell that forms part of a fuel cell is formed by a first expanded metal arranged on a gas inlet side, and a second expanded metal arranged on a downstream side. The first expanded metal is such that mesh is arranged in a straight line, and gas that flows on a gas diffusion layer side is separated from gas that flows on a separator side. The gas flowrate on the gas inlet side is reduced, so the amount of produced water that is carried away is reduced. As a result, the gas inlet side is inhibited from becoming dry at high temperatures.

A rotary slitting blade for fabricating expanded metal products includes opposed end surfaces and an outer circumferential surface extending from one of the end surfaces to the other of the end surfaces. A plurality of notches are formed in each of the end surfaces. The notches include curved surfaces having convex curvatures that smoothly transition into one of the end surfaces and/or the outer circumferential surface. The rotary slitting blade improves the quality of a resulting expanded metal product by reducing or eliminating tears, cracks, and fractures in the expanded metal product.

A method for reinforcing, baffling or sealing a vehicle structure, comprising the steps of providing one or more materials having a horizontal axis, at least one terminating edge, and an initial length, forming openings in the one or more materials, and applying the one or more materials to a location requiring reinforcement, baffling, sealing or any combination thereof.

A method for reinforcing, baffling or sealing a vehicle structure, comprising the steps of providing a material having openings formed within the material so that the material may be stretched to fit a particular vehicle structure.

The invention relates to a method of manufacturing a heat and humidity exchange plate of an air-to-air counterflow enthalpy heat exchanger, which comprises a supporting member (101) and at least one polymeric vapour-permeable membrane (102), characterized in that it comprises the following successive steps: a - continuous formation of a semi-finished product for the supporting member (101) in the form of an expanded metal structure (1010) from a strip of thin metal foil (1011), whereby the operations of slitting in the transverse direction, stretching in the longitudinal direction and rolling over the entire width of the strip are successively performed; b - providing the expanded metal structure (1010) according to the preceding step with a thin vapour-permeable polymeric membrane (102); c - on the expanded metal structure (1010) provided with the vapour-permeable polymeric membrane (102), formation of corrugated and embossed shape elements of the future heat and humidity exchange plate (10) of the counterflow enthalpy heat exchanger (1) by means of omnidirectional deformation; d - creating a circumferential shape of the heat and humidity exchange plate of the counterflow enthalpy heat exchanger (1) by removing excess edges.

In addition, the invention relates to a heat and humidity exchange plate (10) of an air-to-air counterflow enthalpy heat exchanger and to an air-to-air counterflow enthalpy heat exchanger with this plate (10).
