Abstract: A tubular elastomer damper (11) has a central shaft (12) disposed within a housing (13) and surrounded by an elastomer member (14). Uniform strain is provided across the elastomer disposed between the central shaft and the housing by either tapering the length of the elastomer from an inner bonding surface (15) to an outer bonding surface (16) such that the radius times the length at each point along the elastomer is equal or by providing a first elastomer layer (28) adjacent the shaft (26) having a high fatigue strain/lower damping ability, a second elastomer layer (29) adjacent the housing (27) having a low strain higher damping ability and an intermediate elastomer layer (30) of moderate strain and damping therebetween such that from the inner to the outer radius of the elastomer member, uniform strain is achieved. By providing uniform strain from the inner to the outer radius of the tubular elastomer damper, temperature increases due to localized high strains are avoided which are detrimental to damper performance. Optionally, axial cooling passages are provided within the elastomer member to dissipate heat to assure operation within design parameters, thus extending the life of the tubular elastomer damper.

Abstract: Accumulated dimensional variations in fuel cells and electrolysis cell assemblies can reduce the efficiency of the assembly and provide leakage paths for fuel and oxidant. A metal compression pad comprised of a metal having an elastic strain of about 3 % to about 40 % at about 2,500 psig can compensate for component dimensional variations and improve inter-cell conductivity at pressures up to and exceeding about 10,000 psig.

Abstract: A method for removing a predetermined amount of material from the inner surface (16, 18, 20, 22) of a circular article (10) which deviates from a true circular configuration. The outer surface (32) of the article (10) is touch probed to determine its true location in space, data are then compared to engineering design data to establish the location of the surface (16, 18, 20, 22) to which material removal is desired. A control computer (70) sends commands to the machine control system, causing the machine to remove the excess material down to the desired dimension. Any deviations from circular are compensated for by moving the article (10) radially relative to the cutting tool as the article (10) moves circumferentially relative to the cutting tool.
