| 20080211310 | PORTABLE POWER SUPPLY APPARATUS CAPABLE OF RECEIVING AC OR DC INPUT POWER - A portable power supply apparatus is provided. The portable power supply apparatus includes an AC-to-DC power adapter, a DC power connector, a DC-to-DC power adapter and an extension power cable. The AC-to-DC power adapter is employed for receiving AC power. The DC power connector is employed for receiving DC power. The DC-to-DC power adapter includes a first DC power input portion, a DC-to-DC power converting circuit and a first DC power output portion. The first DC power input portion is selectively connected to the AC-to-DC power adapter or the DC power connector for receiving a first input DC voltage from the AC-to-DC power adapter or a second input DC voltage from the DC power connector. The DC-to-DC power converting circuit is electrically connected to the first DC power input portion for converting the first input DC voltage or the second input DC voltage into a first DC output voltage. The first DC power output portion is electrically connected to the DC-to-DC power converting circuit for receiving and outputting the first DC output voltage. The extension power cable is connected between the AC-to-DC power adapter and the DC-to-DC power adapter and/or connected to the AC-to-DC power adapter. | 09-04-2008 |

| 20080203845 | Insulating Mask Arrangement, Armature and Electrical Machine - The invention relates to an insulating mask arrangement for electrically insulating an electric winding from an iron core ( | 08-28-2008 |
| 20100295409 | METHOD AND DEVICE FOR PRODUCING AN ELECTRIC MACHINE WITH A COMMUTATOR - The invention relates to a method and device for producing an electric machine, an electric machine with a commutator, having commutator hooks for fixing electric wire windings with solder arranged between the commutator hooks and the wire winding and two electrodes arranged adjacent to each other which are pressed against the commutator hooks. An electric current is passed through the commutator hooks by means of electrodes such that the solder melts and forms a connection to the wire winding. | 11-25-2010 |
| 20100323552 | PUMPING ASSEMBLY - Electric fuel pumps are already known with a pump housing and a ground terminal, which is provided on a terminal cover, for making contact with an electrical ground, in which the pump housing and the ground terminal are connected to one another via a ground connection, which has a first contact section for making contact with the pump housing and a second contact section for making contact with the ground terminal. The first contact section is provided on the outer circumference of a terminal cover and, after installation, is pressed with a contact pressure against the inner face of the pump housing. Since the inner face of the pump housing has increasingly been provided with an electrically insulating anticorrosion coating, however, when the terminal cover is pressed into the pump housing, touching contact with the pump housing does take place which is usually also electrically conductive, but as a result of the electrically insulating coating has a high electrical resistance. In the case of the conveying assembly according to the invention, the impedance of the contact-making is reduced. The invention provides that the first contact section is designed to have sharp edges in such a way that, when it is pushed into the pump housing, it passes locally through an electrically insulating layer formed on the pump housing. | 12-23-2010 |
