GLAZED ICE CONTROL: THE 'REDREX'

THE REDREX, A DEVICE DESIGNED TO PREVENT SKIDDING ON ICE OR HARD SNOW, HAS BEEN SUBJECTED TO NUMEROUS TESTS IN FRANCE. IT CONSISTS OF A LARGE BRUSH WITH SPIKES. A DETAILED DESCRIPTION IS PRESENTED. IT IS EXTREMELY SIMPLE TO OPERATE- THREE KNOBS ON THE DASH-BOARD. A CAR CARRYING THIS DEVICE MOVES AT AN APPROXIMATE SPEED OF 90 KM/H. THE METHOD CONSISTS IN APPLYING A FORCE ON THE CARRIAGEWAY IN THE LONGITUDINAL AXIS, AS FAR AS POSSIBLE BEHIND THE CENTRE OF GRAVITY, AND APPLYING IT CONTINUOUSLY IN THE OPPOSITE DIRECTION TO THAT OF THE SPEED VECTOR OF THE CENTRE OF GRAVITY. THIS FORCE IS IN THE RANGE OF 80 TO 250 KGS ON THE GROUND FOR A VEHICLE WEIGHING 1200 KGS. FITTING THE DEVICE DOES NOT CAUSE ANY DAMAGE TO THE VEHICLE, AND THE CONSUMPTION OF CURRENT IS LOW. ITS WEIGHT VARIES DEPENDING ON THE SIZE OF THE VEHICLE TO WHICH IT IS FITTED. /RRL/LCPC/ SERC - ONSER/
