Abstract: User data is stored in at least one record in at least one predefined, logic data storage area. One respective record ID is assigned to the at least one record. The record ID includes a uniqueness stamp that is unique in the respective predefined data storage area, a unique ID of the predefined data storage area in which the respective record is stored, and a logic position of the respective record within the respective predefined data storage area. A record test value is determined and stored for the user data and the respective associated record ID of the respective record. Data storage area information containing the ID of the respective predefined data storage area and data on at least one value range of the uniqueness stamps of the records currently stored in the respective predefined data storage area is assigned to the respective predefined data storage area.

Abstract: A single-chip computer includes at least one first processor core and at least one second processor core constructed on a common chip. The at least one first and the at least one second processor cores are interconnected via a processor interface. Data can be read via a separate or common memory interface from a separate or common data memory respectively and/or stored in said data memory. The single-chip computer includes an encryption and decryption unit which is assigned to the at least one processor core and which is constructed and functionally arranged between the at least one second processor core and the memory interface in such a way that the data which can be exchanged between the at least one second processor core and the data memory can be encrypted and decrypted by the encryption and decryption unit.

Abstract: The present invention relates to a preemergence method of selectively controlling weeds in crops of cereals, and to a composition therefor.Up to now it has been virtually impossible to use s-triazines, phenylureas and other photosynthesis inhibitors as preemergence herbicides in cereals, especially wheat and barley, because of their too potent action. This invention solves the problem by providing a composition for the preemergence control of weeds which, in addition to containing such photosensitive inhibitors, contains a diphenyl ether or pyridylphenyl ether derivative as antagonistic component which neutralizes or greatly diminishes the harmful action in cereals.

Abstract: A pair of .omega.-section metallic channels are juxtaposed to form a hollow core with their flat flanges coextensively contacting one another. This core is advanced in steps having a length equal to an even multiple of the predetermined distance toward a work station. Strips are pulled off a pair of supplies at this station and the ends of these strips are advanced toward locations on the core which are spaced apart by the predetermined distance. These strips are advanced by an increment on each step advance of the core. The ends of the strips are spot welded to the flanges on the respective side of the core and the end sections are cut between incremental advances of the strips and step advances of the core to leave a pair of strip arms welded to the core and spaced longitudinally apart by the predetermined distance. The free end of each arm is formed with a split and these split ends are bent in opposite directions to opposite sides of the split.
