Scrivanow. The experiments to which it has been
submitted are, in some respects, sufficiently extraordinary to cause us
to make them known to our readers, along with the inventor's description
of the apparatus.
Mr. Scrivanow's intention appears to be to apply this pile to the
lighting of apartments, and even to the running of small motors, and,
for the purpose of actuating sewing machines, he has already constructed
a small model whose external dimensions are 160 x 100 x 90 millimeters.
"My invention," says the inventor, "is intended as an electric pile
capable of regeneration. The annexed Fig. 1 shows a vertical arrangement
of the apparatus, and Fig. 2 a horizontal one. In the latter, two
elements are represented superposed.
"My pile consists of a prism of retort carbon (a) covered on every side
with pure chloride of silver (b). The carbon thus prepared is immersed
in a solution of hydrate of potassium (KHO) or of hydrate of sodium
(NaHO), marking 1.30 to 1.45 by the Baume areometer, the solvent being
water.
"In the vicinity of the carbon is arranged the plate to be attacked--a
plate of zinc (c) of good quality. The surface of the electrodes, and
their distance apart, depends upon the effects that it is desired to
obtain, and is determined in accordance with the well known principles
of electro-kinetics.
