| 20090267426 | Liquid-cooled electric machine and method for cooling such electric machine - The present invention relates to an electric machine with a machine housing, in which a rotor and a stator winding are accommodated, wherein the stator winding includes winding heads arranged on opposite sides each in a winding head space, and with a cooling device which includes a liquid cooling circuit with a stator jacket cooling and cooling coils as well as a fan connected with the rotor for circulating air in the machine housing. The invention furthermore relates to a method for cooling such electric machine. In accordance with the invention it is provided that the cooling coils extend through the winding head spaces outside the winding heads and the fan includes two fan wheels each associated to a winding head space for generating an air flow circulating inside each winding head space, which by means of air duct and/or guiding means in the respective winding head space is circulatingly passed over the exposed cooling coils and through the winding heads. By cooling down the circulating internal air directly in or at the winding head space, a highly efficient cooling of the winding head space can be achieved, without having to sacrifice a compact construction. | 10-29-2009 |
| 20110248110 | Self-Propelled Surface Milling Machine with Electrical Mill Roll Drive - The present invention relates to a self-propelled surface milling machine, preferably in the form of an asphalt-milling machine, snow-milling machine or Surface Miner, having a mill roll which is drivable about a rotational axis, and a mill roll drive comprising an electrical motor which is accommodated within the mill roll, wherein stator and rotor of the electrical motor are accommodated within a dust and air-tightly sealed motor housing. It will be suggested to associate a cooling device comprising a closed circuit liquid cooling system to the electrical motor located within the milling roll body. Due to the high heat capacity of a suitable coolant, such as oil or mixed water and glycol small volume flows and hence small conduit cross sections will be sufficient. On the other hand, any incorporation of dust into the mill-roll drive as well as any formation of dust by discharge air can be avoided by the closed form of the circuit liquid cooling system. | 10-13-2011 |
| 20110248654 | Self-Propelled Working Machine with Electrical Drive System and Processes for Operating the Same - The present invention relates to a self-propelled working machine, especially in the form of a surface milling machine, such as asphalt-milling machine or snow-milling machine comprising a main operating unit and/or a drive unit, which is operable in a steady-state or near steady-state operating status and is drivable by a drive device comprising at least an electrical motor, the electrical motor being associated with a start-up including a frequency converter for the limitation of starting current. The invention also relates to a process for operating such a self-propelled working machine. According to the invention an operating circuit for steady-state operation is provided, comprising a jumper for bridging the frequency converter following starting or reaching steady-state operational status. Optionally, the jumper is switchable to activate or inactivate the frequency converter of the start-up circuit, respectively. | 10-13-2011 |

A constructed DNA molecule, expression systems, and host cells containing the molecular complex are also disclosed. The invention also relates to a system containing a first DNA molecule encoding the nucleic acid aptamer of the present invention and a second DNA molecule encoding a fluorescent protein capable of being bound by the first domain. Methods of detecting a molecular target and determining location of a molecular target using the nucleic acid aptamer of the invention are also disclosed. | 08-06-2009 |
| 20100062946 | GENOME-WIDE METHOD FOR MAPPING OF ENGAGED RNA POLYMERASES QUANTITATIVELY AND AT HIGH RESOLUTION - A method is provided for detecting genome-wide transcriptionally-engaged RNA polymerases. The method can also be used to assess status and regulation of gene promoters. The method comprises permeabilizing a cell of interest or isolating the nucleus from a cell of interest; performing a nuclear run-on (NRO) reaction with the permeabilized cell or isolated nucleus, wherein a purifiable nucleotide analog is added to the NRO reaction; optimizing the number of bases traveled by engaged polymerases for high resolution and low bias for nucleotide content of transcribed sequences by limiting a second nucleotide concentration or duration of the NRO reaction; isolating NRO-RNA from the NRO reaction; hydrolyzing the NRO-RNA isolated from the NRO reaction to optimize resolution of polymerase location; selecting hydrolyzed NRO-RNA with a solid support to obtain an enriched, purified fraction of the hydrolyzed NRO-RNA; enzymatically repairing the hydrolyzed NRO-RNA; and ligating the hydrolyzed NRO-RNA to compatible adapter oligos. | 03-11-2010 |
| 20100099749 | Nucleic Acid Inhibitors Of Glutamate Receptors - The present invention relates to novel nucleic acid ligands or aptamers that bind to and inhibit the activation of the α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) subtype of ionotropic glutamate receptors. Also disclosed is a novel combination of technologies, i.e., SELEX and laser pulse photolysis for the selection and screening of aptamers that inhibit receptor function and are useful therefore, in the treatment of diseases associated with excessive activation of ionotropic glutamate receptors. | 04-22-2010 |
