TESTING PROTECTION GIVEN BY SAFETY HELMET.—This is the equipment by which the Canterbury University Industrial Development Department is testing motor-cyclists’ safety helmets. An accelerometer in the falling block measures the force with which it drops on the helmet. A strain gauge load cell records the impact on the “head” inside and transmits it to the cathode ray oscilloscope which is photographed in the equipment at the rear. It is believed that these two readings can be correlated to the indentation made on a small aluminium disc below the helmet assembly, thus greatly simplifying the apparatus. The engineers concerned are Mr F. W. Seldon (back) and Commander H. Lynch.
