20080222837 | Compact vacuum cleaning device - A compact vacuum cleaning device for automatic cleaning of smooth and textile floor coverings, particularly in the private home sector, has a housing, a suction mouth on the underside of the housing, a cleaning roller disposed in a roller chamber, a dust collection container, a suction fan, an electrical travel drive, control electronics, and a power source. The device height of the vacuum cleaning device is less than 180 mm. The maximal suction air stream that enters through the suction mouth, passes through the dust collection container, and leaves the vacuum cleaning device through the suction fan, is greater than 15 l/s. The maximal suction power is greater than 10 W. | 09-18-2008 |
20090119871 | Electric vacuum head - An electric vacuum head for a vacuum cleaner has a housing, a cleaning device that can be driven by an electric motor disposed within the housing in a motor chamber, a vacuum mouth on the underside of the housing delimited by vacuum mouth edges, and a vacuum connector. The motor chamber has at least one air entry opening for entry of air to cool the electric motor, and at least one air exit opening. The air exit opening is disposed on the underside of the housing so that the cooling air that exits from the air exit opening during operation of the electric vacuum head enters into the vacuum mouth by way of at least one of the vacuum mouth edges. | 05-14-2009 |
20100050373 | Suction nozzle for a vacuum cleaner - A suction nozzle for a vacuum cleaner has a housing, a vacuum mouth disposed on the floor side in the housing, a cleaning roller mounted to rotate in the housing and driven by an electric motor, and a rechargeable battery unit for the energy supply of the electric motor. Via a rear connecting piece, the suction nozzle can be connected to a suction tube or a suction hose of a vacuum cleaner. The electric motor has a rated power of between 50 and watts, and the rechargeable battery unit has an energy density, relative to its total volume, of more than 200 watt-hours per liter (Wh/L). | 03-04-2010 |
20110078871 | VACUUM-CLEANER POWER-BRUSH ATTACHMENT - A power-brush attachment usable in combination with a line-voltage source and with a vacuum-cleaner suction intake has a housing having a lower wall formed with an opening and a connection—suction tube and/or hose—on the housing engageable with the suction intake. The housing has a passage extending between the connection and the opening for drawing particles in the opening. A rotary brush in the housing is exposed in the opening and engageable therethrough with a floor underneath the housing. A low-voltage electric motor is connected to the brush for rotating same. A low-voltage power source, typically a battery, in the housing is also connectable to the motor for powering same without connection to the line-voltage same. A power converter and electrical line are connectable between the line-voltage source and the electric motor for powering the motor from the line-voltage source. | 04-07-2011 |

20090197993 | PREPARATIONS FOR USE IN CONCRETE - The invention provides the use of mixtures based on aqueous dispersions of polychloroprene to produce fiber products finished therewith, a process for the production thereof and the use of these finished fiber products to produce textile-reinforced and fiber-reinforced concrete and other products based on cement. | 08-06-2009 |
20090311506 | INDUCTION-ASSISTED PRODUCTION METHOD - In a production method for producing molded articles from fiber composites, superparamatic particles are selected which become coupled to an external alternating magnetic field. These superparamagnatic particles are added to a resin portion of a strip-shaped starting material further comprising reinforcing fibers. The strip-shaped starting material is then continuously advanced, and, while being advanced, heated by coupling-in an external alternating magnetic field to which the superparamagnatic particles in the resin portion become coupled. Next, the heated starting material is continuously molded into a molded article; and the resin portion in the molded particle is cured. | 12-17-2009 |
