  • Patent number: 9976245
    Abstract: A method of operating a dispensing system for a washing machine including a suds container for receiving wash liquid and at least one supply container for receiving a treating agent. The method includes selecting and activating a wash or treatment cycle from a plurality of wash or treatment cycles using an input device. The treating agent for delivery to the suds container is selected based on suitability information corresponding to the selected wash or treatment cycle. The treating agent is delivered to the suds container at the start of the activated wash or treatment cycle. The activated wash or treatment cycle is performed using a controller.

  • Publication number: 20140329905
    Abstract: The present invention relates to a method of identifying a subject being susceptible to a co-treatment with an histone deacetylase 10 (HDAC10)-inhibitor, said subject being in need of and/or being treated with cancer therapy against a cancer, comprising the steps of a) determining the amount of an HDAC10 gene product and/or an autophagy-related gene 4D (ATG4D) product in a cancer sample from said subject, b) comparing the amount of said HDAC10 gene product as determined in step a) with a reference amount for said HDAC10 gene product and/or the amount of ATG4D product as determined in step a) with a reference amount for said ATG4D product, and c) identifying a subject being susceptible to co-treatment with an HDAC10-inhibitor.

  • Patent number: 8484950
    Abstract: A configuration for purification of an exhaust gas flow of an internal combustion engine includes at least one exhaust gas line having an element for exhaust gas purification with a first end face and a second end face. The exhaust gas flows through the element from the first end face to the second end face. An adding device is provided downstream of the element for adding a reactant to the exhaust gas flow. The adding device is positioned at a distance of no more than 30 mm from the second end face of the element in such a way that at least part of the added reactant strikes the second end face of the element. A method for adding a reactant into an exhaust line during the operation of an internal combustion engine is also provided.

  • Patent number: 8361955
    Abstract: The present invention is concerned with the therapy of neuroblastoma and related diseases. Specifically, the present invention relates to a method for treating or preventing neuroblastoma comprising administering to a subject a therapeutically effective amount of bone morphogenetic protein 4 (BMP4). Preferably, said BMP4 is applied together with chemotherapy and/or radiation therapy.

  • Patent number: 8359888
    Abstract: A dispensing system for powdered treating agent for use in a washing machine includes a supply container for the treating agent, a delivery device configured to deliver the treating agent to the washing machine through a connecting hose, and a dosing device for dispensing the treating agent from the supply container to the delivery device. The supply container has an agitator with a first vertical rotatable shaft and rotatable blades. The dosing device includes a cylindrical chamber, with a compartmented wheel having spokes disposed therein. The compartmented wheel is disposed below a bottom of the supply container and is coupled to a second vertical rotatable shaft. The cylindrical chamber has an inlet opening disposed in the bottom of the supply container and an underside of the cylindrical chamber has an outlet opening to the delivery device. The compartmented wheel is also coupled to the vertical shaft of the agitator.

  • Patent number: 8220293
    Abstract: A treating agent dispensing system for a washing machine including a base unit and at least two supply containers removably and securably disposed on the base unit. The at least two supply containers are respectively configured to receive a treating agent. The treating agent is a powdered treating agent or a liquid treating agent. A delivery device is disposed in the base unit and is operable to deliver the treating agent to the washing machine through a hose.

  • Patent number: 7849676
    Abstract: A method for adding at least one, in particular liquid, reactant, to an exhaust gas stream of an internal combustion engine includes adding a reactant flow to the stream downstream of an element provided for an at least partial conversion and/or at least partial elimination of at least one component of the stream, so that at least part of the reactant flow impinges on the element. This achieves rapid evaporation of the reactant flow. Impinging on the element, which is hot during operation, i.e. at temperatures of 400° C. and more, causes rapid evaporation and, because of a preferably porous coating of the element, take-up of the reactant solution into the element with successive evaporation. Urea, in particular, can be evaporated quickly, effectively and virtually completely upon introduction into an exhaust system as a reducing agent for selective catalytic reduction of nitrogen oxides, in particular in a downstream SCR catalytic converter.
