  • Patent number: 7507574
    Abstract: The present invention provides a modified Saccharomyces yeast which produces significantly lower levels of ethanol than wild-type yeast under aerobic conditions and saccharide concentrations of 2% glucose, and which exhibits a growth rate of at least 30% of the wild-type yeast, preferably containing a chimeric construct of at least 2 saccharide transporters, nucleic acid molecules encoding the chimeras and polypeptides encoded by such sequences, and methods of using the modified yeast for preparing products in the yeast.

  • Publication number: 20080217153
    Abstract: An insulating element for a medium-voltage switchgear has a terminal at the busbar end and an outgoing cable. A circuit-breaker is embedded in the insulating element. The insulating element supports a first contact point that is connected to the circuit-breaker and is used as a bearing point for a movable switching contact of a disconnector, and an additional contact point for the movable switching contact. A favorable structure for producing medium-voltage switchgears in general for primary and secondary power supply systems while reducing expenses, the additional contact point is also configured as a bearing point for the movable switching contact, the movable switching contact is alternatively mounted on the additional contact point rather than on the first contact point, and the additional contact point is alternatively connected to the outgoing cable rather than to the terminal at the busbar end.

  • Publication number: 20080024116
    Abstract: A coupling electrode for capacitive voltage tapping within an insulating body of a component which has at least one conductor section which is embedded in the insulating body and to which a high-voltage potential can be applied, having an electrode section which is composed of a semiconductive plastic, and having a connecting element which is electrically connected to the electrode section and is designed such that it can be passed out of the insulating body. A holder which is composed of a non-conductive material and, is connected to the electrode section and has the positioning means, which allow isolated mounting of the electrode section.
