  • Patent number: 11977400
    Abstract: An analog circuit arrangement (1) to variably set a voltage Uout, within defined voltage limits, has a non-inverting adder (10) with a positive input (11). A voltage divider (20), with at least a first stage (21) and a second stage (22), is connected to the positive input (11) of the adder (10). At least one stage has a parallel circuit of n resistors (R1, R2, . . . , Rn) that are each connected in series in a conduction path (L1, L2, . . . , Ln) to an overcurrent protection device (F1, F2, . . . , Fn). At least one device (30) actively changes one or more of the overcurrent protection devices (F1, F2, . . . , Fn) into a state that interrupts the respective affected conduction path (L1, L2, . . . , Ln).

  • Patent number: 9175602
    Abstract: The invention relates to a V engine, especially a diesel engine, comprising a first cylinder bank and a second cylinder bank, said V engine being designed for two-stage charging by means of a low-pressure exhaust gas turbocharger and a high-pressure exhaust gas turbocharger. The invention is characterized in that the low-pressure exhaust gas turbocharger and the high-pressure exhaust gas turbocharger are respectively arranged on the front of a cylinder bank above a main output element of the V engine.

  • Publication number: 20120255299
    Abstract: The invention relates to a V engine (1), especially a diesel engine, comprising a first cylinder bank (2) and a second cylinder bank (3), said V engine being designed for two-stage charging by means of a low-pressure exhaust gas turbocharger (4, 5) and a high-pressure exhaust gas turbocharger (6, 7). The invention is characterised in that the low-pressure exhaust gas turbocharger (4, 5) and the high-pressure exhaust gas turbocharger (6, 7) are respectively arranged on the front of a cylinder bank (2, 3) above a main output element (23) of the V engine (1).

  • Patent number: 5652102
    Abstract: Primers specific for enterohemorrhagic Escherichia coli (EHEC) 0157:H7 bacteria have been designed which are useful for detecting the bacteria by polymerase chain reaction methods. The primers were derived from DNA sequences contained within a 60-MDa plasmid which is present in most EHEC. The primers may also be used in combination with primers derived from other sequences of significance, the conserved sequences of Shiga-like toxins I and II and the eaeA gene, in a single simultaneous amplification reaction to specifically identify EHEC serotype 0157.

  • Patent number: 5545523
    Abstract: The present invention relates to novel compositions comprising Bovine Herpesvirus-1 (BHV-1) specific oligonucleotides which are useful as nested primers to amplify sequences of the BHV-1 gIV gene during enzymatic nucleic acid amplification. The invention also provides a method for the detection of BHV-1 which may be present in a clinical specimen, particularly bovine semen, using the BHV-1 specific nested primers and enzymatic nucleic acid amplification. The present invention also relates to a BHV-1 specific oligonucleotide which can be used as a probe to facilitate detection of amplified products derived from BHV-1 gIV gene sequences.
