摘要:
The invention relates to processes for converting CO by microbial fermentation to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. More particularly the invention relates to a method for producing one or more products from a CO comprising substrate, the method comprising a natural gas reforming step for producing a syngas stream, and converting at least a portion of CO from the syngas stream to one or more products including ethanol.

A system and method for members of the public to retrieve and verify the accuracy of emergency response information that is associated with a communication device and would be utilized in an emergency services network should the device be used to summon emergency services. Such information can include location of the origin of a call for emergency services, identification of emergency service providers who would respond to such a call, and/or the level of accuracy of location information that would be provided to an emergency service dispatcher were such device used to summon emergency services.
摘要:
The invention relates to a method for determining the winding temperature (TW) of the stator winding of a three-phase AC motor, in particular a pole-changeable asynchronous motor. For determining the winding temperature (TW) of the stator winding of three-phase AC motors that have an unfavorable ratio of the active power to the dissipation power and react sensitively to temperature changes and changes in a main voltage, and for readily determining the heat dissipation power (PV) from the winding temperature (TW) of the stator winding, it is proposed to determine the reference temperature (TG) and the motor current (IM) simultaneously at consecutive points in time, and to determine the winding temperature (TW) by calculating step-by-step sequentially the change in the winding temperature (TW) at a point in time (tn) and adding this change to the winding temperature (TW) of the immediately preceding point in time (tn−1). The change of the winding temperature (TW) associated with a point in time (tn) is proportional to the electrical heat dissipation power (PV) that is converted into heat in the stator winding at the point in time (tn) and to the temperature difference between the reference temperature (TG) of the housing at that point in time (tn) and the winding temperature (TW) at the immediately preceding point in time (tn−1). The winding temperature (TW) of the immediately preceding point in time (tn−1) is also used for calculating the heat dissipation power (PV).
