Abstract: A household appliance includes a cabinet-shaped housing comprised of a plurality of walls. At least one of the walls has an arrangement of embossings. The arrangement of embossings includes a first embossing arranged centered in relation to a center of the at least one wall and configured in the shape of a ring when viewed from above. A second embossing is arranged outside the first embossing in substantial concentric relationship to the first embossing and configured in the shape of a ring when viewed from above. At least one third embossing is arranged outside the second embossing and has a strip-shaped configuration. The presence of embossings in the at least one wall is able to reduce vibrations and thereby significantly reduce the amount of unwanted noise.

Abstract: A washing machine contains a friction damper device for a washing unit comprising a tub, a washing drum which is rotationally mounted in the tub and a drive for the washing drum. The washing unit is supported in an elastic manner by at least one damper counter to a lower frame part of the housing. In order to prevent the vibratory behavior of the oscillating unit from being influenced above the rotational speed of the resonance, the friction in the damper above the rotational speed of the resonance can be reduced. As a result, at least one friction covering which interacts directly on a piston rod of the damper is pretensed by an energy store counter to the piston rod and can be displaced away from the piston rod by activating an actuator.

Abstract: A process for enantioselectively preparing 3-azidocarboxylic acid derivatives comprises reacting 3-sulfonatocarboxylic acid derivatives with an alkali metal azide in a solvent selected from the group comprising certain carboxamides; a solvent mixture which comprises such carboxamides; a solvent mixture of water and a solvent miscible homogeneously with water; water with the proviso that the addition of a phase transfer catalyst is not used in the reaction in water; and DMSO. The resulting products are optionally reduced to 3-aminocarboxylic acid derivatives.

Abstract: A transverse cutting device for a continuously fed-in web of material which is wound onto sequentially positioned winding tubes, wherein the transverse cutting device includes a cutter block which can be displaced transversely with respect to the web of material and can be driven by a drive mechanism in the displacement direction, and in which a cutting blade for the transverse cutting of the web of material is held, wherein the cutter block has an applicator brush trailing the cutting blade, by which the leading edge of the web of material formed while being severed can be successively placed against the circumference of a waiting winding tube. Also, a winding device for winding a continuously fed-in web of material onto sequentially provided winding tubes is proposed, which has a transverse winding device.

Abstract: A method and apparatus for winding a continuously delivered film web onto successively delivered winding tubes with a rotatably drivable contact roller, a winding station, associated with the contact roller, for the winding tube for winding the coil, a winding preparation station for receiving a new winding tube and beginning to wind the film web, and a transverse-cutting device for cutting the film web crosswise between the winding station and the winding preparation station. Associated with the winding preparation station for the new winding tube are a charger for generating an electrostatic charge of the new winding tube and a blower device for subjecting the film web to a blown air stream aimed counter to the feeding direction of the film web.

Abstract: Non-synchronized, manually shiftable transmissions of modern vehicle types are actuated by means of an automated transmission control, and the driver can optionally select any gear by means of an actuator which is electrically connected to the transmission control device. In general terms, the method of this invention includes the operator generating a signal indicating a desire to shift the transmission. The transmission then automatically begins implementing the shift. If the currently engaged gear is not disengaged within a preselected time period, because the system cannot achieve a break torque condition, for example, the system signals the driver to manually operate the clutch. A visual and audible signal preferably are provided to the driver. Once the driver manually operates the clutch, the system is able to complete the desired shift.

Abstract: A method of engaging and disengaging transmission gears in a vehicle is provided. A controller processes an initial torque representing an engine torque and an estimated zero torque representing an estimate of a transmission output shaft torque. The controller also sets a high and low band torque about the estimated zero torque. Once the above torques have been determined, the controller compares the initial torque to the high band torque. If the initial torque is below the high band torque, the controller increases the engine torque to the high band torque. If the initial torque is greater than the high band torque, then no preliminary adjustments to the engine torque need be made. At least one shift valve is energized when the engine torque is equal to or greater than the high band torque. The engine torque is decayed by the controller to the low band torque to facilitate engaging and disengaging transmission gears.

Abstract: A process for the control of non-synchronized, manually shiftable vehicle transmissions which are actuated in vehicles of new construction by means of an automated transmission control system whereby the driver is able to select a desired gear by means of an operating unit which is connected electrically to the transmission control system. When the vehicle is stopped and the clutch is disengaged practice of the invention prevents a situation in which the engagement of a gear is prevented by a tooth-on-tooth position of the transmission claws. The disclosed process makes it possible to engage the selected gear in all operating states of the vehicle in a simple and reliable manner. In this regard, a desired gear is first selected, and the clutch is then disengaged. When a suitable speed of the transmission input is then reached, a gear to be engaged is automatically engaged. Thereby, the engagement of a gear when the vehicle is stopped is systematized and facilitated for the driver.
