Abstract: A door system for at least one door, the door system including door components, with one of the components being designed as a control unit. The control unit and at least one other door component are connected to one another via a first communication bus. An access system with an above door system and with a computing unit are related, with an image of the door system stored in the computing unit, the door components connected to the first communication bus each having an identifier. The identifiers are stored as part of the image of the door system in the computing unit and/or with past and current operating states of the door system stored in the computing unit. An access system with at least one of the above door systems is related, with at least one door system having an authentication device configured to receive an access attribute for authentication.

Abstract: A method for commissioning a door system with the door system having door components, with at least one door component being designed as a control unit, with the method including the following steps: storing an electronic configuration of the door system in the control unit and/or a mobile terminal, and carrying out at least one commissioning step by the electronic configuration.

Abstract: A method for installing door components includes at least the following steps: a. providing at least one preconfigured door system type by way of an electronic configuration system for selection by a user, wherein the at least one preconfigured door system type is able to be retrieved from a database by way of the electronic configuration system, wherein at least one preconfigured door system type is able to be preselected by the configuration system by way of at least one technical and/or functional user specification, wherein the door system type contains stipulated door component types, and b. electronically providing preconfigured technical data of the selected door system type in order to carry out the installation on site.

Abstract: An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c1) a nonionic surfactant selected from c11) the condensation product of a C6 to C18 fatty alcohol or C6 to C18 fatty acid and a mono- or disaccharide; and c2) an anioni

Abstract: The stratified two cycle engine comprises: a cylinder having an upper end and a lower end, a head at the upper end and fuel and air intake ports at the lower end; at least one spark plug mounted in the head; a sleeve in the cylinder having an upper end and a lower end and the cylinder having exhaust ports at the upper end which are covered and uncovered by the upper end of the sleeve; a piston in the sleeve and connected to a crank shaft; a first exhaust manifold at one side of the cylinder at the upper end thereof adjacent one exhaust port in the cylinder and having first exhaust gas throttle valve means associated therewith; at least a first and a second fuel and air intake manifolds at one side of the cylinder and at the other side of the cylinder in communication with first and second fuel and air intake ports in the cylinder; throttle valve means in each intake manifold; a reed cage assembly in each intake manifold adjacent the associated intake port for injecting a fuel and air mixture into the cylinder
