Abstract: A watering warning device (1) for determining watering intervals for at least one plant to be monitored, having at least one moisture content sensor (2), a timer (6) and an evaluation unit (3) is described. The evaluation unit (3) is designed for determining the time (tG) of the next necessary watering operation for the at least one monitored plant in dependence on a characteristic watering curve (S) over time (t), the watering curve (S) being determinable in a self-learning manner in at least one learning phase from a low moisture value (FGN), measured at a watering time, the high moisture value (FGH), measured after completion of the watering operation following the watering time, and the time (tN) until the low moisture value (FGN) is reached, determined with the timer (6) or extrapolated.

Abstract: A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device is an opto electric measuring device with at least two light paths. Each of the at least two light paths has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind. The light-emitting elements determine the angle position of the element aligning with the direction of the wind.

Abstract: The invention relates to an apparatus for producing a plasma and treating substrates therein. The plasma produced by means of microwaves serves to coat a substrate which is situated in a chamber (5) having metal walls (6,7,12,13). The microwaves are repeatedly reflected at the metal walls (6,7,12,13), so that the chamber (5) has numerous microwave modes. By means of permanent magnets, which are placed either inside the chamber (5) or outside the chamber (5) in the vicinity of the substrate that is to be coated, it is possible to produce within this chamber (5) an electron-cyclotron resonance which permits a locally controlled ignition of the plasma.

Abstract: The plasma produced by means of microwaves in the presence of a magnetic field and a gas serves to coat a substrate which is situated in a chamber having metal walls. The microwaves are repeatedly reflected at the metal walls, so that the chamber has numerous microwave modes. By means of permanent magnets, which are placed either inside the chamber or outside the chamber in the vicinity of the substrate that is to be coated, it is possible to produce within this chamber an electron-cyclotron resonance which permits a locally controlled ignition of the plasma.

Abstract: A microwave plasma method/of depositing a coating of a prescribed material on the internal surface of a pipe by means of a reaction of a vapor phase providing a prescribed material in which:(a) an atmosphere at a pressure less than atmospheric pressure containing the vapor phase is introduced into the pipe,(b) microwave energy is beamed into the pipe which is propagated along the length of the inside of the pipe,(c) a magnetic field is generated in a localized area of the pipe in which electron cyclotron resonance occurs for the the frequency of the microwaves, and in which, pressure, field strength of the magnetic field and the power of the high-frequency field are selected that a low-pressure gas discharge results in the area of the magnetic field to trigger the reaction furnishing the prescribed material, and(d) in which the magnetic field and thus the plasma are transposed along the length of the pipe.

Abstract: A fluid-tight coupling device for microwave radiation of high energy incls a tubular dielectric window which is sealingly connected to one end of a waveguide supplying the microwave radiation and forms a continuation of the waveguide. The other end of the tube forming the window is tightly sealed by an essentially conical reflector. The tube forming the window is surrounded on the outside by a cup-shaped waveguide portion. The reflecting surface of the reflector and the reflecting inner surface of the cup-shaped waveguide portion are formed such that the microwave radiation emerging from the waveguide is reflected through the tubular window into the cup-shaped waveguide portion and from the latter to the open end of the waveguide portion in such a manner that an input mode of type TE.sub.mn is transformed into itself or a well-defined adjacent mode TE.sub.m'n', further secondary modes are minimized and at the same time return waves are also minimized.
