Dart Drug Corp. profits for the three months ended April 30 inched up to $367,000 (22 cents a share) from $343,000 (20 cents) a year earlier, the Landover-based retailer announced yesterday.

Sales jumped to $60.5 million from $56.3 million, aided by the opening of several new stores.

Sales and earning totals include Dart's share of Crown Books West, a joint venture with a California drug chain, as well as sales of Dart-owned Crown stores in the Washington area and its Trak-Auto parts stores.

Dart said it opened 4 book stores and 5 Trak Auto units during the quarter, remodeled 4 drug store/home center combinations and closed 2 stores in the Washington area.

Survival Technology Inc. of Bethesda reported profits for the latest quarter rose sharply but not enough to offset declines earlier in the year.

For the three months ended April 30, the maker of emergency medical devices earned $268,000 (10 cents a share), up from $65,000 (3 cents) in the same period a year ago. Sales for the period climbed 36 percent to $4.6 million from $3.4 million.

For the first nine months of its fiscal year, Survival Technology earned $490,000 (19 cents) on sales of $12.7 million compared with $803,000 (32 cents) on sales of $11.7 million.

The increase in third-quarter sales and profits was due primarily to increased shipments to the Defense Department of automatic injectors for defense against chemical warfare.

McCormick & Co. the big Baltimore food and flavoring maker, reported that its earnings for the second quarter jumped to $3.8 million (31 cents a share) from $2.5 million (22 cents) last year while sales climbed to $154.4 million from $121.6 million.

For the first half of 1980, McCormick reported profits of $7.6 million (66 cents) on sales of $287.4 million compared with earnings of $4.1 million (36 cents) on sales of $234.8 million in the same period a year ago.
