A surge in revolving credit charges and automobile lending sent consumer installment credit up 6.1 percent in April to $2.93 billion, the Federal Reserve Board said yesterday.

The April increase followed a revised increase of 0.7 percent, or $322 million, in March. The Fed had originally reported a $63 million decline in March. All rates were computed on an annual basis.

Revolving credit outstanding rebounded 12.7 percent to $1.4 billion in April following a decline of $496 million in March.

U.S. Judge Bars Bid for Burlington A federal judge yesterday temporarily blocked an investor group from pursuing its $1.82 billion hostile bid to acquire Burlington Industries Inc. after ruling that there was possible evidence the group began its bid based on inside information about the giant textile company.

"Burlington has shown a likelihood that it will be able to prove that Samjens utilized inside information received from {James} Ammeen in connection with Samjens' tender offer," U.S. District Judge Eugene Gordon wrote in his order in Greensboro, N.C.

Samjens is the name of the investor group that is led by New York financier Asher B. Edelman and Dominion Textile Inc. of Canada.

Burlington had filed the suit in a bid to block the takeover bid, charging that Ammeen, a former Burlington executive, had released confidential information to PaineWebber Inc. and the investor group, prompting the hostile takeover bid.

The decision temporarily bars Edelman and Dominion, which already own 13.4 percent of Burlington, from proceeding with their offer to buy the remaining shares for $77 each. Burlington has already accepted a rival $76 a share bid.

Kraft to Buy All American Gourmet Kraft Inc. will acquire the All American Gourmet Co. from General Host Corp. for $296 million, eliminating about $155 million of long-term debt for General Host, the companies said yesterday.

All American Gourmet, which produces frozen foods under its Budget Gourmet label, had sales of about $195 million for the 12 months ended April 19.

The acquisition is Kraft's fourth in three years in the frozen-food industry.

General Host, which is headquartered in Stamford, Conn., owns about 75 percent of All American's 16.4 million shares outstanding. Kraft Inc. is a division of Dart & Kraft Inc. and headquartered in Glenview, Ill.

About 6.8 million of General Host's shares are held in escrow in case holders of $110 million of exchangeable subordinated notes seek to convert their debt to equity.

Kraft plans to make a cash tender offer for all of the notes at a 15 percent premium over face value.

Allegis to Meet With Pilots Union Embattled Allegis Corp. executives yesterday said they probably will meet with the United Airlines pilots union, which has proposed a restructuring plan that would dismember the company.

Allegis, the parent company of United, has been rocked by a bid for control by Coniston Partners, a New York investment company that controls about 13 percent of Allegis stock.

To discourage hostile suitors, the former UAL Inc. has proposed a recapitalization plan and transferred notes that could be converted into approximately a 16 percent stake in the company to Boeing Co. as part of a jet deal.

The pilots' plan, delivered Thursday to Allegis Chairman Richard Ferris, would give the pilots control of the airline and would sell most or all of the company's other major assets: Hilton International, Hertz Corp. and Westin Hotels.
