| 20100168747 | Method and apparatus for removal of tissue - A surgical instrument includes a deflectable cutting element extending from the distal end of the instrument. The deflection of the cutting element is controllable based on a user operating a moveable member of the instrument. The deflectable cutting element is normally disposed within a circumferential region defined by the distal end of the instrument. The moveable member can be moved in relation to the instrument to deflect the deflectable cutting element, such that the cutting element is at least partially outside of the circumferential region. The extent that the cutting element is outside of the circumferential region is a function of the position to which the moveable member is moved in relation to the instrument. The instrument further includes direct imaging of the distal end, such that the deflection of the cutting element for selective removal of bone tissue at the distal end of the instrument can be controlled in real-time. | 07-01-2010 |

| 20090211096 | Method for manufacturing a solid housing - A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, includes the following operations or steps: a) providing a base element made of a magnetic or magnetizable material, b) carburizing and/or nitride-hardening of at least one subarea of the base element by diffusion of carbon and/or nitrogen under thermal treatment for forming a non-magnetizable structure in the area of the diffusion zone, and c) finishing the base element so created until an intended geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines. | 08-27-2009 |
| 20100281691 | METHOD FOR MANUFACTURING A SOLID HOUSING - The method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve, is characterized in that the following method steps are used: a) providing a sheet metal strip made of a magnetic or magnetizable material, b) introducing an additive into a middle area of the sheet metal strip and fusing there for forming a non-magnetizable structure, c) cutting the sheet metal strip into a sheet metal piece of desired width, d) deforming the sheet metal piece into a sleeve shape, e) mutual fastening of the cut edges now facing each other and running in the longitudinal direction of the sleeve for forming a sleeve blank, f) final machining of the sleeve blank until a desired geometry of the housing is achieved. The housing is suitable in particular for use in fuel injectors in fuel injector systems of mixture-compressing spark-ignition internal combustion engines. | 11-11-2010 |

| 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 |

| 20090256125 | Winch - The present invention relates to a winch for elevating plant, in particular cranes, cable-operated excavators and similar construction machinery, comprising a hoisting drum, an electric motor for the drive of the hoisting drum which is received in the interior of the hoisting drum as well as power electronics and/or control electronics for the electric motor comprising at least one frequency inverter and/or frequency converter. In accordance with the invention, the power electronics and/or control electronics for the electric motor are received at least partly in the interior of the hoisting drum. Not only short cabling distances are hereby achieved; interference emissions with negative effects on the electromagnetic compatibility are avoided; and voltage overshoots impairing the service life of the inverter and the motor are reduced, but also a particularly compact construction of the winch is achieved. | 10-15-2009 |

| 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 |
