A group of seven Brazilian students won Owens Corning's Global Design Challenge for their V-shaped bicycle frame made of composites. Twenty-five student teams submitted designs for an affordable ``world bike'' priced around $100.
Called the Kangaroo, the Brazilian bike's sleek, simple frame and technical foundation won near-perfect scores from the 10-judge panel.
The student winners, from the University of SÃo Paulo, are: Marcelo Uller, Monica Duarte Aprilante, Emiliano Martus Barelli, Carlos Augusto Magnani Fantinato, Glaucia Nogueira Goncalves, Fernando M.M. Ribiero and Vania Regina Velloso. The first-place winners and their university will split a $10,000 prize.
Owens Corning, based in Toledo, Ohio, presented the awards in New York on June 13.

RTP says compound ideal for gaskets
RTP Co. of Winona, Minn., claims its proprietary additives in resins provide pliable plastic compounds that also are highly conductive.
The company said these compounds may be used to create thermoplastic gaskets to protect business equipment from electromagnetic and radio frequency interference. Its materials can achieve volume resistivity of 1 ohm per centimeter, RTP said.
Use of the compounds allows parts to be joined electrically, without the need for connecting pins, screw or wires, RTP claims.
Cost of the olefinic version of the company's compound ranges from $7.50-$17.50 per pound. Compounds also are available in polyurethane, polyester and polyether block amide thermoplastic elastomers.
The compounds can be modified for specific requirements, the company said.

Device makes film for transmission analysis
Spectra-Tech Inc. of Shelton, Conn., introduced the Universal Film Maker, a device that presses polymers into films for transmission analysis with an infrared spectrometer.
Heated platens produce test films with a matte finish. They do not cause the interference fringes produced by smooth films that make testing more difficult.

Spirex says software simplifies inventory
Spirex Corp. of Youngstown, Ohio, has issued three new software packages to simplify inventory and maintenance.
Spirex Link tracks inventory on Spirex products such as feedscrews, barrels, endcaps and valves.
The program tells plant officials when to reorder and check parts for wear.
Maintenance Professional for Extrusion tracks maintenance schedules and spare parts inventories and keeps a record of repairs and project histories.
Another software program is designed for use with injection molding.
All software is compatible with Microsoft Windows. Spirex in-cludes free technical support for one year.

Optometrix unveils line scan camera
The Series 2000 line scan camera from Optometrix Inc. of West Haven, Conn., scans up to 1,000 measurements per second.
The measurement range can be adjusted in length and dimension, covering a range of blown film sizes.
Instead of measuring bubble size at a single point on its circumference, the camera monitors changes in the bubble diameter. It can automatically adjust outputs from the air ring and internal bubble cooling. It also can reduce edge trim scrap

Ford's nylon pedal cuts number of parts
Ford Motor Co. developed a nylon accelerator pedal for an undisclosed 1999 model vehicle.
The pedal promises to cut weight and part count by 50 percent and costs by 10 percent.
AlliedSignal Engineered Materi-als of Morristown, N.J., will supply Capron 8233, a 33 percent glass-reinforced nylon 6, for the application. AlliedSignal helped design the part, which has a C channel facing the passenger compartment and a reinforcing rib pattern. A simple redesign of the metal pedal gave a part that was too heavy.
Comcorp Technologies of Sydney, Australia, will injection mold the nylon pedal. Ford chose Capron 8233 for strength, proces-sability and surface aesthetics.
