Show Off To Nowhere At 70 Miles Per Hour T PITTSBURGH, PA. This fantastic - looking device resulted when scientists built a highway inside a laboratory. A motorist's dream, it artificially creates all basic driving conditions, but eliminates annoyances like traffic, chickens, slippery pavements and red lights. Better motor fuels are expected from the faster, more accurate testing of gasolines, possible with this Gulf research development. Sketched from life, a test crew here accelerates to 70 m.p.h., the driver not bothering to watch the road. Mileage and test data are recorded on huge instrument board (I) outside car. Rear wheels rotate heavy drums (2) which gear into flywheels (3) electrically manipulated to simulate various vehicle and passenger loads. A combination com-bination electrical motor and absorbing unit (4) creates artificial uphill and downhill grades by speeding or retarding drums. A fan (5) delivers air at velocity proportionate to speed against car, and air conditioner (6) supplies artificial temperatures. Siren (7) warns of mechanical failure. Scale (8) indicates torque; chocks (9) hold front car wheels motionless. 1 |
