Abstract: A method for making a membrane electrode assembly includes the steps of providing a membrane electrode assembly including an anode including a hydrogen oxidation catalyst; a cathode; a membrane disposed between the anode and the cathode; and depositing a peroxide decomposition catalyst in at least one position selected from the group consisting of the anode, the cathode, a layer between the anode and the membrane and a layer between the cathode and the membrane wherein the peroxide decomposition catalyst has selectivity when exposed to hydrogen peroxide toward reactions which form benign products from the hydrogen peroxide. The peroxide decomposition catalyst can also be positioned within the membrane. Also disclosed is a power-generating fuel cell system including such a membrane electrode assembly, and a process for operating such a fuel cell system.

Abstract: A tank filler neck comprises an outer wall (1), an inner wall (2) and an inner space (19) closed off from the environment during operation. In order to enable the pressure in this space (19) to be equalized in both directions, a negative and positive pressure relief valve (20) is provided in the annular space (18) between outer wall (1) and inner wall (2). The valve comprises a partition (21) with holes (30) distributed over the circumference, said partition dividing the annular space (18) between outer wall (1) and inner wall (2) into a first annular space (22) connected to the atmosphere and a second annular space (23) connected to the inner space (19), a first valve ring (31) in the first annular space (22) and a second valve ring (32) in the second annular space (23), which valve rings have first zones (40, 42) and second offset zones (41, 43) alternating in the circumferential direction, see FIG. 4.
Abstract: The invention relates to a tire valve (10) comprising a valve body (11) which penetrates a bore (21) of a rim (20), particularly a vehicle rim, embodies a bottom valve body section (13) that is disposed on one side (23) of the rim (20), particularly in the interior of the rim, in the mounted state as well as a top valve body section (15) that protrudes from the rim bore (21), and is configured so as to cooperate with a cap nut (17) in the area of the top valve body section (15). The bottom valve body section (13) forms a stop collar (19) which is used as an abutment for a flat peripheral section (27) of the rim bore (21) and widens the bottom valve body section (13) relative to the top valve body section (15) beyond an internal width of the rim bore (21). The peripheral section (27) of the rim bore (21) can be braced against said stop collar (19) by tightening the cap nut (17).
Abstract: A process for manufacturing a disk shaped component comprising fabricating a disk shaped component using a composite material having at least a first material and a second material, wherein the first material is disposed at and proximate to a center portion of the disk shaped component and the second material is disposed at and proximate to a rim of the disk shaped component, wherein the first material comprises a first coefficient of thermal expansion, a first stress value and a first oxidation resistance, and the second material comprises a second coefficient of thermal expansion, a second stress value and a second oxidation resistance, wherein the first coefficient of thermal expansion is greater than the second coefficient of thermal expansion, the first stress value is greater than the second stress value and the first oxidation resistance is less than the second oxidation resistance.
Abstract: An electronic part mounting substrate has a ceramic substrate, a metal member bonded to one side of the ceramic substrate, a metal plate of aluminum or an aluminum alloy, one side of the metal plate being bonded directly to the other side of the ceramic substrate, and an electronic part bonded directly to the other side of the metal plate.
Abstract: A method is provided for inhibiting scale in a hydrocarbon system, including the steps of: providing a hydrocarbon system; providing an aloe-derived scale inhibitor; and mixing the aloe-derived scale inhibitor with the hydrocarbon system in amounts effective to inhibit formation of scale. The scale inhibitor is an aloe vera gel/aloe sap mix dissolved in water at a concentration of between about 5 and about 50% wt/wt, which includes polysaccharides having a hydrocarbon chain structure having carboxyl and alcohol functional groups that interact with divalent ions.

Abstract: A bottle closure includes the unitarily-molded combination of: an internally-threaded sidewall; a tamper indicator ring; and a hinge connecting the ring to the sidewall. The hinge permits the ring to be shifted from an initial position to an installation position. The installation position is essentially coaxially aligned with the sidewall.
Abstract: The invention relates to a method for the preparation of aleurone from bran, in particular, wheat bran, for the extraction of aleuronic cells in particular from wheat grain, whereby the mainly aleurone-containing aleuronic components are separated from the mainly non-aleurone-containing non-aleuronic components in the bran and the aleurone-containing components are then isolated. The separation can be achieved by biochemical/enzymatic means and/or by mechanical-abrasive means. The subsequent isolation and extraction can be achieved by wet and/or dry separating methods.
