Federal REIT now operates 24 shopping centers, including two recent acquisitions in suburban Philadelphia, and real estate assets total $123.8 million -- three times their level of three years ago.

Renovation was almost completed on Wildwood Manor in Bethesda, transforming it from a neighborhood strip center to an upscale, fashion-oriented mini-mall.

DESCRIPTION: Survival Technology designs and manufactures medical devices, including anti-chemical-warfare equipment for the Defense Department and other gear used by ambulances and rescue squads.

DEVELOPMENTS: Survival Tech's earnings plunged in the year ended July 31, 1984; after posting a profit of almost $1 million in fiscal 1983, Survival Tech went $766,000 in the red. The company blamed the loss on delays in a Defense Department contract for its Mark I chemical antidote kit. But it added that the outlook already is brighter for 1985 because of a $9.5 million DOD contract signed in January that has helped it resume production. 64: HALIFAX ENGINEERING INC. 5250 Cherokee Ave.Alexandria, Va. 22312

DESCRIPTION: Halifax provides technical, engineering and support services, primarily to the U.S. government.

In one of its largest contracts, Halifax provides support and technical documentation to the Navy's prime shipbuilder in the Auxiliary Rescue Salvage Program. Halifax tests the safety of ships and publishes technical manuals on equipment and systems. The company also has supported the Amphibious Warfare Division of the Naval Coastal Systems Center in Panama City, Fla. For the past five years, it has evaluated missile systems for the Naval Sea Systems Command and Naval Surface Weapons Center.

The company operates the locks and bridges on parts of the Intracoastal Waterway, and owns a small boatyard in Suffolk, Va.

DEVELOPMENTS: Halifax's earnings grew 7 percent in the fiscal year ended March 31, 1984, to $500,000 from $467,000, and revenue jumped by 18.3 percent to $23.4 million from $19.8 million. But earnings per share slipped to 42 cents from 59 cents because the firm issued additional shares.

In October, Research Industries, an Alexandria-based private investment firm, purchased 15 percent of Halifax's stock, doubling its interest in the firm. The seller was retiring Halifax founder and president Charles A. Webb Jr., who sold his entire interest in the company. Research Industries officials said they acquired the stock "for long-term investment purposes," and denied there was a takeover move in the works.

For the first nine months of fiscal 1985, ended Dec. 31, Halifax reported a net loss of $64,103 (5 cents a share), compared with a profit of $313,479 (29 cents) during the year-earlier period. The loss came despite a 50 percent jump in revenue for the period, to $22.3 million from $14.9 million in fiscal 1984. The company blamed the loss on discontinued operations at its boat- yard in Suffolk, which is up for sale. 65: MICROS SYSTEMS INC. 6901-B Distribution Dr. Beltsville, Md. 20705

DESCRIPTION: Micros Systems designs, manufactures and markets electronic terminals for cash registers and data processing. Its products are marketed to hotel and lodging properties, restaurants, and gas stations and convenience stores.

DEVELOPMENTS: After reporting significant growth for the year ended June 30, 1984, with profits up 56 percent and earnings per share up 36 percent over fiscal 1983, Micros Systems reevaluated its accounts receivable and restated its figures. Now the company reports a 10 percent slide in profits and an 18 percent drop in earnings per share over 1983. These reductions, the company said, are due primarily to "unreserved doubtful accounts receivable and unrecognized inventory obsolescence."

Finances at Micros are not looking any better for 1985. In March the company announced a second-quarter loss of $17,000 compared with a profit of $324,000 for the same quarter in 1984. Revenue remains steady, and the company's president has stated that "sales are strong, its cash position is good, and lender relations are excellent."
