Directors of the International Bank, the Washington-based "merchant bank," have elected Henry N. Conway Jr. and Robert D. Edison executive vice presidents of the international and insurance divisions, respectively. A former senior vice president for banking and finance, Conway now will have overall responsibility for overseas operations. Edison, also formerly senior vice president, will continue to oversee property/casualty insurance operations, which were the primary source of the company's $8.8 million loss in 1984. A bank spokesman said he expects a turnaround from last year's losses in the insurance area when the company announces six-month earnings.

American Security Corp., parent company of American Security Bank, has named Clement Geitner and Junius S. Morgan senior vice presidents. Geitner, who joined American Security in 1979 as international division vice president, will head the bank's loan review division. Morgan, a 13-year veteran of the bank, will oversee the commercial construction financing and account management groups in the real estate division.

Eugene F. Dunn, formerly executive vice president and chief financial officer of Continental Federal Savings Bank, has moved to Perpetual American Mortgage Co., a subsidiary of Perpetual American Bank, in its construction and commercial loan division.
