Title: The Innovations of Stanley Kaufman
Introduction
Stanley Kaufman is a notable inventor based in Dunwoody, GA (US). He holds a total of 5 patents that showcase his contributions to the field of communication technology. His work primarily focuses on advancements in optical fiber cables and insulated conductors.
Latest Patents
One of Kaufman's latest patents is for an optical fiber cable provided with stabilized waterblocking material. This invention includes a core comprising a plurality of coated optical fibers and a filling composition that surrounds the fibers. The fibers and filling material are typically housed within a tubular member, which is then encased in a sheath system. This sheath system consists of longitudinally extending strength members and a plastic jacket. The filling composition contains an oil constituent, which is a high molecular weight aliphatic hydrocarbon, such as polyalphaolefin or mineral oil. To prevent thermal oxidative degradation, a significant percentage of an antioxidant system is incorporated. Additionally, the composition includes zinc dialkyldithiophosphate or diaryldithiophosphate for stabilization and metal deactivation. A styrene-ethylene propylene copolymer is also added to reduce oil separation, while fumed silica is used to impart gel properties to the material.
Another significant patent involves a metallic transmission medium disposed in stabilized plastic insulation. This insulated conductor is designed for use in communication cables and includes a copper conductor along with a composite insulation system comprising two concentric layers. The inner foam layer consists of a cellular plastic material that includes a stabilizer system, while the outer layer, referred to as the skin, is made of a stabilized solid plastic material. The stabilizer system in both layers includes a bifunctional portion that acts as both an antioxidant and a metal deactivator, ensuring high resistance to extraction.
