Abstract: A rubber composition containing reinforcing pigment some of which is preferably silica pigment, sulfur, a vulcanization accelerator, litharge, and a cobalt salt, when coated on brass plated steel cords and vulcanized, adheres tenaciously and permanently to the cords, without the erratic adhesion previously obtained or loss of adhesion in humid atmospheres. A further improvement in adhesion is obtained by including a resorcinol resin in the composition.

Abstract: An improved water-lubricated bearing consists of longitudinal strips of rubber bonded to a rigid backing. The strips are either flat or have a concave surface of less curvature than the journal, and are so thin that the width of each strip is at least 6 and preferably 10 or more times its thickness. The backing may be polyethylene bonded to the rubber during vulcanization.
