A memory system comprised of M memory modules where M-1 of the modules are for storing data bits and the Mth modules is for storing system parity bits corresponding to the data bits stored in the other M-1 modules. Each module has RxC bit locations organized into W internal words of L bits and includes a parity array for storing one parity bit for each internal word, where L is greater than 1, and...

A computer architecture is disclosed which permits intersegment program calls with associated selective allocation of data segments of varying lengths. The calling program controls selective allocation of segments to the called program but the called program controls the lengths of the segments being allocated. In this way, recursive calls to the same program cannot affect the function or data of ...

Aqueous fructose and aldehydes, ketones and/or acetals may be effectively catalyzed into alkylidene fructose derivatives with immobilized acid catalysts. The reaction provides a means for enriching the fructose content of conventional high fructose corn syrups. Perfluorinated acid resins are especially effective catalysts for converting aqueous fructose and acetone solutions into diacetone fructos...

3'-Deoxyadenosine 5'-triphosphate is oligomerized to form (2'-5')-oligo (3'-deoxyadenylate) by incubation with adenosine triphosphate: (2'-5')-oligo adenosine adenyl transferase, in the presence of an inert support carrying a double stranded polynucleotide. The (2'-5')-oligo (3'-deoxyadenylate) is digested with a suitable phosphatase to remove the terminal phosphate groups. The thus produced corre...
