Abstract

139,100. Pape, R. July 21, 1919. Drawings to Specification. Preserving food.-To preserve foods &c., they are stored in chambers in which the ordinary electric potential gradient of the air is neutralized; it is stated that the development of bacteria &c. is thus prevented. The chamber employed is made of metal and is insulated from the earth. Ionization of the air within the chamber is prevented by passing through it a current of air which has been passed over a moistened surface or a metallic conductor. The chamber mav be double-walled, and the inlet ports for air in the two walls so arranged as to prevent the entrance of light and consequent ionization. Passing the air over a moistened surface also serves to increase its electric resistance and thus reduce electric currents in the chamber, but the amount of moisture in the air must be below saturation. A potential gradient in opposition to the normal gradient of the air may also be imposed on the chamber by a dynamo or the like, and may be regulated by clock-work or otherwise in accordance with the known diurnal variations of the atmospheric potential gradient.
