* Emile Ardolino, 50, who won an Oscar for the dance documentary "He Makes Me Feel Like Dancin" and went on to direct the hit films "Dirty Dancin' " and "Sister Act," died Saturday at his home in Los Angeles of acquired immune deficiency syndrome, Ardolino Productions announced. His film version of the perennial George Balanchine ballet "Nutcracker" is scheduled for release tomorrow. His final project was a film production of "Gypsy" starring Bette Midler, which is to be shown on CBS Dec. 12 and in theaters after that. He grew up in New York and won his Academy Award for the 1983 documentary and racked up three Emmys, a dozen more Emmy nominations and credits as producer and director of 28 episodes of PBS' "Dance in America" series by the time he achieved feature film popularity with "Dirty Dancin' " in 1988. The huge box office success starring Patrick Swayze and Jennifer Grey made Mr. Ardolino a force in Hollywood.
* Stanley Robert Rich, 76, an entrepreneur and inventor who devised a scanning sonar for submarines in World War II, died Sunday of cancer at Youville Hospital in Cambridge, Mass. He lived in Grantham, N.H., and Wellesley Hills, Mass. He retired last month as chairman and technical director of Plasmachines Inc. in Natick, Mass., the last of several business ventures he started over the years. Plasmachines is an environmental technology company that makes and sells air-pollution control equipment for combustion engines and industrial use. The New York City native was granted more than 60 U.S. patents and about 500 foreign ones. It was at Harvard that he developed a scanning sonar for which the Navy got the patent and he was awarded two official commendations. In 1950, he formed the first of seven corporations that he founded over four decades to produce and market his inventions, which included high-intensity ultrasonic cleaning devices for industry, acoustic pollution controls, and coal-cleaning devices. The companies he headed as president and as technical director include Rich-Roth Laboratories, Ultra-Viscoson Corp., and Teknika Inc. in Connecticut.
* Daniel J. Krumm, 67, who led Maytag Corp. as it grew into a $3 billion global appliance business, died yesterday of cancer, the company said. The Sioux City, Iowa, native stepped down as Maytag's chairman at the end of 1992, shortly after completing his 40th year with the company. He had remained on the board of directors. He became chairman and chief executive officer of the Newton-based appliance manufacturer after Maytag acquired Magic Chef in May 1986. He presided over the company as it nearly doubled through the 1989 acquisition of the Chicago Pacific Corp. and its Hoover line of floor-care products and appliances.
* Henry J. Opperman, 71, a former television producer and advertising executive who helped produce such early television shows as "Captain Video and His Space Rangers," died at his Raleigh, N.C., home of cancer on Nov. 14. He joined the DuMont Network in New York shortly after serving in the Army during World War II. The network owned what is now WNYW-TV, Channel 5, in New York, and broadcast some of television's first regularly running shows. As director of program planning and development, he served as a liaison between the network and the advertising agencies that created such shows as "The Goldbergs," a situation comedy that began on radio, and "The Plainclothesman," a detective show. "Captain Video," whose actors patrolled the universe in their spaceship called Galaxy, was one of the first children's shows on television.
