Survival Technology Inc. of Bethesda announced that total revenue for the first quarter of its 1980 fiscal year ended Oct. 31 rose 95 percent to $4.2 million from $2.1 million in the same period last year.

Earnings from operations were $475,400 (19 cents a share) compared with $228,700 a year earlier. That does not count a one-time gain in the previous year's period of $109,000 (5 cents), which produced net income of $337,800 (14 cents) for the company.

Survival Technology produces medical devices and services for emergency health care.

Schwartz Brothers Inc., a Washington-based retailer and wholesaler of music merchandise, reported a net loss of $139,685 on sales of $7.68 million for the third quarter compared with net income of $68,031 (9 cents) on sales of $7.73 million in the same period last year.

For the first nine months of the current fiscal year, the company reported a net loss of $236,625 on sales of $21.01 million compared with net income of $184,164 (23 cents) on sales of $21.67 million in the same period a year ago.

James Schwartz, president of the company, blamed industrywide sales problems as the major cause of the adverse results.

United Consoldted Industries, a network of warehouses and jobbers of automotive replacement parts based in Hanover, Md., reported a 6.3 percent increase in sales for the third quarter to $6.27 million from $5.87 million in 1978. However, the company reported net profits of $168,752 (48 cents a share), down from $195,278 (5 cents) last year. Profits for the first nine months of the fiscal year were $357,537 ($1.01) compared with $415,803 ($1.22) in 1978.

The company blamed the decline in profits in both the third quarter and the first nine months of the fiscal year on high interest rates resulting from the Federal Reserve Board's tight-credit policies.
