Composite Rotor Sues Beckman Coulter for Patent Infringement

8th August 2000 0 comments

Composite Rotor, Inc., an industry leader in the manufacture of rotors for use in laboratory centrifuges, has filed a complaint for patent infringement against Beckman Coulter, Inc. in the United States District Court for the Northern District of California in San Jose. Composite Rotor specializes in the design and manufacture of centrifuges made of composite materials, similar to the materials used in the aerospace industry. Composite material centrifuge rotors are stronger and lighter than the metal rotors they replace, reducing acceleration and deceleration times of the centrifugation process, reduces the load, and wear and tear, on the centrifuge and reduces centrifuge damage in the event of rotor failure. In addition, composite materials in centrifuge rotors resist corrosion from many solvents used in centrifugation better than other rotor materials. Composite Rotor holds several patents covering the use of composite materials in centrifuges. Composite Rotor has sued Beckman for infringing two of Composite Rotor’s patents, U.S. Patent Nos. 5,382,219 and 5,562,582. “We have been attempting to resolve this matter informally with Beckman, but after Beckman ignored our correspondence for months on end it became apparent that Beckman was not participating in those discussions in good faith,” said Composite Rotor CEO Gus Malek-Madani. “As a result, we have been forced to resort to using the courts to protect our intellectual property.” Composite Rotor Inc. was founded in 1990 to design, manufacture and market rotors, the key component used in centrifuges. CRI has established its brand of advanced centrifuge rotors KOMPspin(R), as a technologically leading product in the research laboratory market replacing aluminum and titanium rotors. Later the company applied carbon fiber composite technology and advanced centrifuge system technologies to a series of table-top centrifuges. The core technology of the company revolves around applications of aerospace composite structural material and techniques to centrifuge rotors as well as the latest advancements in centrifuge drive systems.

Polyacrylontitrile-based Carbon Fiber Project Planned

8th August 2000 0 comments

A 400t/a polyacrylonitrile-based carbon fiber project will be built at Zhejiang Jiaxing Zhongbao Carbon Fiber, as the State Development Planning Commission has approved the project feasibility study report. The project construction capacities are 400t/a polyacrylonitrile-based carbon fiber and 3m sqm pre-dipped material. The product scheme is 50k and 60k big-tow polyacrylonitrile-based carbon fiber and 120-175g pre-dipped material per square meter. The project will introduce overseas advanced process technology and critical equipment. After the project is operational, 920t/a polyacrylonitrile-based raw filament yarn will be brought into the domestic and overseas markets. The total project investment stands at RMB 247.3m, including RMB 240.79m fixed asset investment and RMB 6.51m working capital. The project capital is RMB 75m, accounting for 30.3 percent of the aggregate investment, and the remaining RMB 172.4m will be financed by the China Construction Bank. The project is an equipment import project, free from tariff and import-linked VAT.

Lockheed Martin Begins Inspecting F-22 Composite Parts With Laser Tool

1st August 2000 0 comments

Lockheed Martin Aeronautics Company has begun inspecting composite F-22 parts using its patented laser ultrasonic technology system, known as LaserUT(TM). This technology enables affordable, high-volume inspection of complex-contoured composite parts. This marks the first production aircraft parts that have been inspected using the advanced laser testing system, following years of research and prototyping by Lockheed Martin and its predecessors at Fort Worth. The company has nine patents issued or pending for this technology. The next-generation combat aircraft will have a high percentage of graphite-epoxy composite material in their structures. Extensive inspection is required to ensure no flaws exist in the many layers that comprise the finished composite components. The LaserUT system requires very little set-up time and performs high-resolution inspection in a tenth of the time compared to current water ultrasonic inspection systems. “We recently inspected a large section of the F-22 engine inlet duct in less than two hours using LaserUT compared to 24 hours with the first-generation inspection equipment,” said Russell W. Ford, vice president of Aerostructures Manufacturing at Lockheed Martin Aeronautics Company. “With this 90 percent reduction in inspection time, we expect to shorten manufacturing span times by many weeks and to realize substantial cost savings over the course of F-22 and Joint Strike Fighter production. Also, the accuracy of the system will help us achieve even higher standards of quality.” The LaserUT system at Fort Worth, the first of its kind, can handle complex-shaped parts up to 54 by 27 by 21 feet. It is located in a multimillion-dollar facility that has been under construction since early 1998. The technologies were developed with company funds and support from the Air Force Research Laboratory’s Materials and Manufacturing Directorate at Wright-Patterson Air Force Base, Ohio. “This inspection system is expected to offer high payoffs in materials selection,” said Bob Rearden, vice president and F-22 program manager. “We originally designed a complex section of the inlet duct as a titanium weldment because it was not practical to inspect this configuration made from composite materials. But now we anticipate switching this component to composite material with significant reductions in cost and weight.” Lockheed Martin Aeronautics is continuing research and development in this high payoff inspection technology to further reduce inspection times to meet JSF affordability requirements. More systems will be added as production rates of the next-generation fighters increase. LaserUT is being considered for other aerospace facilities in Lockheed Martin.

Ford to Boost Fuel Economy of SUVs by 25 Percent

1st August 2000 0 comments

Ford Motor Co.(F.N), attacking complaints about gas-guzzling sport utility vehicles, said Thursday it will raise the average fuel economy on its hot-selling SUVs by 25 percent by 2005. Ford Chief Executive Officer Jac Nasser announced the program in a speech in Washington, where Congress is considering regulations to raise the fleet average fuel economy of light trucks to 27.5 miles per gallon, the mark required for car fleets, from 20.7 mpg. The better mileage will come from a variety of areas, including new generations of engines, more use of lightweight materials such as composites, and improved aerodynamics.

Honeycombed Plastic – Steel and Timber of the Future

1st August 2000 0 comments

Kalman Engineering Co. has developed and patented a family of extremely lightweight, strong and inexpensive load-bearing structures – ValueComb(TM). ValueComb(TM) is made of a honeycomb-like plastic core between two so-called “facesheets. ValueComb(TM) can be produced in virtually any extrudable size with great consistency and at such a low cost that they will become the basic “value-added” raw material for most load-bearing structures of the future – replacing metals, timber, brick, gypsum, paper, paint and other traditional building materials in houses, bridges, ships, furniture, railroad cars, shipping boxes, and a host of other uses. The strength-to-weight ratio of ValueComb(TM) is claimed to be close to space and aircraft structures. The company has finished the development, patenting and business planning stage. Now it seeks money to build the first prototype plant and sell the initial product.

Indigenous company breathes a new life into the building technology

1st August 2000 0 comments

in NigeriaEco-Building System Nigeria Limited is introducing a new dimension into construction work that may even make it possible to construct a skyscraper in a few days. Eco-Building Managing Director, Dr. Maduka Nwakwesi says that the company has mastered the art of infusing speed into construction work through a self-developed eco-crete panel/modular system which ensures the completion of about 10 bungalows in a month, 10 three-bedroom flats in two weeks and five, 5-bedroom duplex with detached quarters in three months. Ninety-five per cent of the materials are sourced locally, he stressed. The pre-fabricated materials, a mixture of cement, polymers, fibreglass and sand which is poured into prepared moulds to dry. Though the house is light, it is five times stronger than concrete houses. Due to the use of fibreglass, the only imported component, the house can resist fire, water and termites, although the company is working on replacing the fibreglass which it imports with a mixture of coconut fibre and jute.
