Abstract: A substrate includes a heat slug that is disposed in a cavity in the substrate. An engineered filler material is disposed in the cavity over, under, and/or around the heat slug. The engineered filler material is a thermally conductive particle material having a composition that can be adjusted based on a desired coefficient of thermal expansion. An electronic device can be attached to the substrate over the heat slug and the engineered filler material. The heat slug and the engineered filler material provide, or are part of, a heat transfer dissipation path for the electronic device.

Abstract: Trans-polyisoprene composition of improved dimensional stability and stiffness are prepared by blending trans-polyisoprene with glass fibres and reinforcing silica. A crystalline wax may also be added to the compositions, to provide easier moldability.

Abstract: A self-propelled combine has a forward transversely elongated harvesting platform mounted on the forward end of a forwardly and downwardly inclined feeder housing through which the crop is fed to a separating mechanism in the combine body. A plurality of axially transverse paddle type impellers are mounted in the feeder housing and extend between the opposite sides of the housing immediately above the housing floor, the impellers being rotated in the same direction so that the impeller paddles move rearwardly along the floor, whereby the crop material is engaged by successive paddles and moved upwardly and rearwardly along the housing floor to the separating mechanism.

Abstract: Bromobutyl alone or blended with other free radical curable polymers or with free radical curable monomers can be vulcanized by heating in the presence of free radical agents.
