New Management: Bristol Research Corp. said Thursday that a new investor team has taken over management of the industrial computer products company, and that the company has filed for a secondary stock offering to the public.

Steven P. Doehler, a principal in the Doehler Group, an Easton, Md., firm that has invested in Costa Mesa-based Bristol, has been named as Bristol’s new president, chief executive, chief financial officer and chairman. He replaces W. Jerry Mezger, who joined the company in November to help turn the unprofitable firm around.

The company also said it has filed a statement with the Securities and Exchange Commission to issue 1.2 million shares of common stock for between $2 and $4 a share, said Monica Flores, a company spokeswoman.
