Title: Process for improving the interfacial bonding between fibers and rubber
Inventor: PARKER DANE K
IPC: C08G18/72
Filed: 1993-02-04
Abstract: Abstract of the Disclosure PROCESS FOR IMPROVING THE INTERFACIAL   BONDING BETWEEN FIBERS AND RUBBER       Polymeric reinforcements are commonly used to strengthen rubber articles.  For instance, rubber articles are commonly reinforced with high strength cords, polymeric fabric and/or short fibers.  It is often difficult to attain a high level of adhesion between such reinforcements and rubber compositions. This is especially true in cases where difficult to bond materials, such as polyaramide fibers, are employed.  By utilizing the process of this invention, the adhesion between polymeric reinforcements and rubber compositions can be greatly improved.  This invention more specifically discloses a process for preparing a rubber article containing a polymeric reinforcement which comprises:  (1) plasma treating the polymeric reinforcement in a manner whereby reactive groups containing Zerewitinoff active hydrogen atoms are bonded to the surface thereof; (2) incorporating the polymeric reinforcement having Zerewitinoff active hydrogen atoms bonded to the surface thereof into an uncured rubber composition, wherein said rubber composition has pendant blocked isocyanate groups bound thereto; and (3) curing the uncured rubber into the desired shape for the rubber article at an elevated temperature sufficient to deblock the isocyanate groups bonded to the uncured rubber allowing for the isocyanate groups to react with the Zerewitinoff active hydrogen atoms bonded to the surface of the polymeric reinforcement.

Title: Absorbent article having enhanced wicking capability
Inventor: COUTURE-DORSCHNER LAURIE
IPC: A61F13/53
Filed: 1993-08-17
Abstract: An absorbent article is disclosed which exhibits enhanced wicking capability. The absorbent article includes a liquid-permeable cover, a liquid-impermeable baffle and an absorbent enclosed therebetween. The absorbent is constructed of first, second and third members. Each member has a wicking capability for body fluids discharged by a human body. The first member has a high wicking capability, the second member has a lower wicking capability than the first member, and the third member has a higher wicking capability than the second member. The different wicking capabilities of the three members promotes a systematic distribution of body fluid away from the body-side cover down into the absorbent article. The second member also has an equal or greater width than either the first or third members so as to provide a visual cue of when the absorbent article is in need of changing. By changing the absorbent article when the second member appears to be soiled, the user can prevent side leakage and soiling of an adjacent undergarment.

Title: Humanized antibodies to ganglioside gm2
Inventor: NAKAMURA KAZUYASU
IPC: C12N15/13
Filed: 1993-09-07
Abstract: Chimeric human antibody expression vectors are constructed by inserting the antibody heavy chain variable region-encoding cDNA and antibody light chain variable region-encoding cDNA isolated from hybridomas producing a mouse or rat monoclonal antibody reacting with the ganglioside GM2 respectively into an expression vector for use in animal cells which contains the human antibody heavy chain constant region- or human antibody light chain constant region-encoding cDNA. The expression vectors are introduced into animal cells and the transformant thus obtained is cultured for the production of a chimeric human antibody reacting with the ganglioside GM2. In contrast to mouse monoclonal antibodies, the chimeric human antibodies of the invention will not cause anti-mouse immunoglobulin antibody production in the patient's body but shows a prolonged blood half-life, with a reduced frequency of adverse effects, so that it can be expected to be superior to mouse monoclonal antibodies in the efficacy in the treatment of human cancer, for instance.
