A LAMPPOST THAT BENDS AND A NEW HEADLIGHT WIPER FOR CIRCULAR HEADLAMPS

Brief details are given of two new devices developed by the National Swedish Board for Technical Development: (1) A lamppost which, on impact, immediately loses its rigidity, collapsing underneath the car and helping to bring it to A halt. The casing of the lamppost is held together with thin rods, spot - welded to the inside; on impact all the welds snap simultaneously. The car carreers on with the post still anchored to the ground and trapped beneath the undercarriage. The car is pulled gradually to a halt, as the braking energy is absorbed along the length of the post. (2) the new headlight wiper is designed for circular headlamps. Unlike conventional wipers, it does not move forward and backward but in a contorted circle. The blade is semi-circular and attached to a movable ring around the outside of the lamp. When the cleaning fluid is squirted on the glass, the ring begins to rotate, pulling the blade out until one end touches the centre of the glass and the other rests on the edge. After two revolutions, the blade returns to rest on the ring. A cable connects the ring to the motor which operates it and which can run up to four wipers. When the blade wears out replacement is simply a matter of prising off the ring and snapping on a new one. /TRRL/
