Abstract

896,692. Electrostatic recording apparatus. ARMOUR RESEARCH FOUNDATION OF ILLINOIS INSTITUTE OF TECHNOLOGY. June 9, 1958, No. 4900/62. Drawings to Specification. Divided out of 896,691. Class 40 (2). The Specification relates to the charge injection method of electrostatic recording described in Specification 896,691, from which the present Specification is divided, but the claims are directed to the neutralization of the external field by subjecting the record medium to a supply of ions.
