NEW PRIMARY BATTERY

AN AUSTRALIAN INVENTION. A uew primary battery with a voltage of 2.5 per cell and lasting for 50 hours with a current drain of one ampere has been invented by a Mr. W. A. Bleeck, of Queensland. The battery operates on the Teclanche principle, but is totally different in action. ‘Ihe elements are of carbon and zinc, but two liquids are used instead of the customary salammoniac. In addition, the cell cannot become polarised, so, therefore, can give a constant current for many hours. The cell consists of an outer container of glass; a perforated carbon cylinder, a special porous pot placed inside the carbon, and a zine pole of special design. Current is produced immediately, and for the demonstration a 16 c.p. lamp was lit, from two cells connected in series, within half a minute of assembling them. Mr. Bleeck hopes to leave shortly for England to have the battery manu. factured, as difficulty has been experlenced in obtaining the necessary materials in Australia, On test the cells showed 44 volts when discharging at 1{ amps, so it will be seen it is suit. able for most radio work, ae =
