Abstract: The invention relates to a biocidal composition comprising a carboxyl functional polymer and biocidal quaternary ammonium ions. The polymer is a copolymer comprising maleic acid monomer units and/or anions thereof and vinyl ether comonomer units. The composition may be in the form of a film on a surface or in the form of a solution.

Abstract: The invention relates to a control unit with storage batteries for an electromotive furniture-drive device with at least one drive unit which can be coupled to a piece of furniture or a lifting device. The control unit comprises a first housing part, provided with electronic components, and a second housing part comprising the storage batteries. For the purposes of establishing an electrically conductive connection between the storage batteries and the electronic components, at least one plug-in connection is provided, wherein at least one plug is provided on a housing part, and this plug interacts with a complementary plug-in socket on the other housing part. The control unit is distinguished in that the plug is arranged such that it allows an electrically conductive contact to be established approximately perpendicularly to the longitudinal extent of the housing parts.

Abstract: The invention relates to a control system for adjustment apparatuses that can be actuated by way of electric motors, which apparatuses are provided for beds, more particularly for hospital beds, nursing beds or the like, and also to a method for generating reliable control signals for adjustment apparatuses that can be actuated by way of electric motors, which apparatuses are provided for beds, more particularly for hospital beds, nursing beds or the like, with at least one control unit and at least one operating apparatus, comprising a manual switch for the patient, wherein the method comprises the monitoring and processing of output signals from the operating apparatus, and the generating of control signals in the control unit on the basis of output signals from the operating apparatus, wherein the monitoring and processing of the output signals is brought about at least in part by means of at least one processor in the control unit, and the method is distinguished by virtue of the fact that at least one co
