Title: Method and circuit arrangement for the acceptance and forwarding of message cells transmitted according to an assynchronous transfer mode by an asynchronous transfer mode switching equipment
Inventor: DANNER GERD
IPC: H04L12/56
Filed: 1991-08-08
Abstract: ABSTRACT OF THE DISCLOSURE For receiving and forwarding message cells transmitted according to an asynchronous transfer mode (ATM) by an ATM switching equipment which comprises a multi-stage reversing switching matrix network, each of the message cells has a routing information block having a plurality of routing information corresponding in number to the plurality of switching matrix stages to be traversed located in front thereof within the ATM switching equipment and the routing information just evaluated for the forwarding of a message cell through one of the switching matrix stages is subsequently displaced to the end of the respective routing information block. It is thereby provided that each of the routing information of the routing information block has a separate security information attached thereto and the security information is falsified, together with the displacement of a routing information to the end of the respective routing information block. A message cell is thereby only forwarded via a switching matrix stage when the routing information to be evaluated for that purpose has been recognized as being free of error on the basis of the attached securityinformation.

Title: Scanner to combine partial fragments of a complete code
Inventor: LAPINSKI CHARLES
IPC: G06K7/10
Filed: 1991-09-23
Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored.

IPC: A01N63/50
Filed: 1991-04-24
Abstract: Two new Bacillus thuringiensis strains, which are deposited at the DSM under accession nos 5870 and 5871, produce new crystal proteins during sporulation that are toxic to Coleoptera and that are encoded by new genes. The crystal proteins contain protoxins, which can yield toxins as trypsin-digestion products. A plant, the genome of which is transformed with a DNA se-quence that comes from either one of the strains and that encodes an insecticidally effective portion of its respective protoxin or encodes its respective toxin, is resistant to Coleoptera. Each strain, itself, or its crystals, crystal proteins, protoxin, toxin and/or insecticidally effective protoxin portion can be used as the active ingredient in an insecticidal composition for combatting Cole-optera.
