Abstract: A composite friction assembly is disclosed which comprises at least one friction member and a support member. Each of the friction member and the support member have a composition comprising a thermosettable resin and a filler material. The friction member and the support member each have a planar surface, with the respective planar surfaces being joined at their interface, so as to define a boundary layer. The composition of each member is substantially confined to separate sides of the boundary layer whereby the composition of the friction member does not substantially penetrate beyond the boundary layer into the composition for the support member and the composition for the support member does not substantially penetrate beyond the boundary layer into the composition for the friction member. Among the disclosed embodiments of the present invention is a brake pad, such as that used in vehicular brakes. The present invention further relates to a method of making such a composite friction assembly.

Abstract: The invention concerns an agent for enhancing the keeping quality of bodies of slaughtered animals, parts of bodies of slaughtered animals, and hamburger patties, a process for the use thereof, and bodies of slaughtered animals, parts of bodies of slaughtered animals, and hamburger patties which are preserved according to the process.

Abstract: A composition is provided, which comprises a purified cytoplasmic extract from eggs of Xenopus laevis which is capable of supporting activation of human sperm and complete replication of a human sperm genome. Methods of using the extract to achieve complete replication of the sperm genome are disclosed. A flow cytometric method for quantitatively monitoring replication of human sperm genomes is also disclosed. This method can be used for clinical assessment of sperm quality in a test sample of human sperm from an infertile male donor.
