  • Method and device for preventing corrosion of a gas inlet nozzle during nitric acid condensation
    Patent number: 8176654
    Abstract: By a method and a device for preventing corrosion on and in the region of a gas inlet nozzle during nitric acid condensation, contact of the condensing gas with the nozzle and with the surroundings of the nozzle are supposed to be minimized. This is achieved in that the gas inlet nozzle has a sleeve on the inside in the transition region to the interior of the condenser, by which sleeve a gas inlet orifice in the form of an annular gap is formed, whereby the annular space is provided with at least one feed opening for secondary air, so that an enveloping flow of secondary air is produced around the entering NO gas.

  • Method for screwing skirt and crown parts of a metal piston together
    Patent number: 8176629
    Abstract: A method for screwing together two metal parts that are spaced apart from one another close to a screw connection element and elastically deformable relative to one another, and for the remainder lie against one another. In order to obtain a firm and secure screw connection, with little expenditure of torque, one of the metal parts is deformed, before the metal parts are screwed together, in such a manner that regions close to the screw connection element come close to one another, and the metal parts are then screwed together. A region of the one metal parts remains deformed after they have been screwed together, as a result of the screw connection element.

  • Method for producing a cast component with a cast-in pipe
    Patent number: 8176967
    Abstract: A method produces a cast component of an internal combustion engine with a cast-in pipe. Expendable molds and a permanent pattern, or permanent molds are used in the method. A solid core mold is mounted in a split outer mold. To solve the problem of the pipe changing its position during the casting of the component, a separate pipe holder is integrated into the outer mold or the core mold. The pipe is inserted into a retaining section of the pipe holder that is configured in such a manner that it locally surrounds the outer circumference of the pipe at least in part and with little play so that the pipe can expand in the axial direction during casting but is secured against displacements in radial directions caused by buoyancy forces of the liquid casting material. Subsequently the component is cast.

  • Power screwdriver
    Patent number: 8171827
    Abstract: The invention relates to a power screwdriver (10) comprising a motor (12) and a control circuit (22) which switches the motor (12) off by means of a switch-off signal (s_Stop) when it reaches a preset desired torque value (Md_Soll), and a supporting arm (18) which absorbs energy during screwing. The invention is characterized by a voltage limiting circuit (46) that limits the motor voltage (u_Mot) occurring on the motor (12) when the energy stored in the supporting arm (18) of the motor (12), which is driven as the generator and rotates counter to the direction of drive, is dissipated, to a predetermined limiting voltage (u_Lim). The limiting voltage (u_Lim) is fixed in such a manner that the motor (12) is capable of rotating without counter-torque counter to the direction of drive when operated in the generator mode and that yet no inadmissible overvoltages occur.

  • Turbomachine
    Patent number: 8172503
    Abstract: A turbomachine has a shaft mounted in a shaft housing, and a rotor in a rotor housing at one end of the shaft, for compression, expansion, or transport of a working gas. The shaft is mounted by hydrostatic, gas-lubricated bearings that have a connector to a compressed gas line that is connected with a pressure region of the turbomachine. A portion of the gas that is passed from the pressure region is applied to the bearing. The shaft is mounted so that the bearing effect is at least extensively independent of the rotational speed of the shaft, thereby guaranteeing support of the shaft during startup of the turbomachine, and good rigidity and low sensitivity to pressure surge stresses. The pressure in the connector to the compressed gas line is at least 5 bar greater than the pressure in the region of the ventilation connector.

  • Play menu and group auto organizer system and method for a multimedia player
    Patent number: 8166416
    Abstract: A multimedia play menu is generated into an auto playgroup organizer system for a multimedia player by using intelligence cursor/scroll sequence functions programmed for operation by an input device such as a hand-held mobile mouse. The intelligence cursor/scroll can sense any type of digitalized item or symbol displayed on the LED or LCD screen of the multimedia player. When the intelligence cursor/scroll function senses a click/press sequence symbol representing the position of a song, it will start to carry out a click/press sequence function as a user wishes. The more clicks/presses are applied by the intelligence cursor/scroll on the sequence symbol before a song/item, the higher the position for that song/item is created, analyzed, recorded and carried out.
