US Patent:

53506693, Sep 27, 1994

Filed:

Jan 19, 1994

Appl. No.:

8/183486

Inventors:

David R. Whitcomb - Woodbury MN
William C. Frank - Roseville MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G03C 1498

US Classification:

430618

Abstract:

Novel silver-carboxylate/1,2-diazine compounds having the formula: ##STR1## wherein: R. sup. 1 represents either an alkyl, aralkyl, cycloalkyl, or alkenyl group of up to 29 carbon atoms; or an aryl group of up to 14 carbon atoms; and and R. sup. 2 represents either hydrogen, an alkyl group, a cycloalkyl group fused to the 1,2-diazine ring, or the atoms necessary to complete a 5- or 6-membered aromatic ring fused to the 1,2-diazine ring. The novel silver-carboxylate/1,2-diazine compounds are coordination compounds of two silver-carboxylate molecules and two molecules comprising a 1,2-diazine nucleus. These compounds can serve as the silver source in a black-and-white thermographic or photothermographic element or as the oxidizing agent for a dye-based thermographic or photothermographic color-imaging construction.

US Classification:

395610

Abstract:

A system is disclosed for using an independent transaction processing application as a service routine for a client application where the independent transaction processing application is programmed for independent input and output. The independent transaction processing application does not have be reprogrammed for usage as a service routine. A transaction manager provides transaction control for a service request from the client application. A display processing system manages input and output associated with processing the service request. A database management system that is used by the independent transaction processing application distinguishes whether the transaction manager or the independent transaction processing application is providing transaction control.
