  • Patent number: 5533391
    Abstract: An electrical rain sensor to be mounted on the outside of a main frame of an openable window, particularly a skylight, comprising a sensing element with two electrodes mounted opposite one another in an insulating holder, the distance between the electrodes being less than the size of a raindrop. To the electrodes an electric circuit is connected which by detection of a change in an electrical quantity caused by the presence of raindrops, activates a maneuvering device which closes the window. The holder (8) is produced by molding of an electrically insulating thermoplastic, wherein the supply lines to the electrodes (15, 16) as well as a heating element for the drying of the sensor are produced as inserts in the holder by molding of an electrically conductive thermoplastic polymer into excavated recesses and/or grooves in the holder (8).

  • Patent number: 5300867
    Abstract: In an electric drive arrangement for a cord winding and dewinding winch (22), in particular for cord-operated screening and opening/closing devices for windows and doors, in which the operating cord (4) is connected with said device for moving it in one direction when winding up the cord on said winch (22), the latter being turned in one direction by means of an electric motor (12), while movement in the other direction is effected by a spring force acting on the device while dewinding the cord from the winch (22), the latter being turned by the electric motor (12) in the opposite direction, the winding and dewinding winch (22) for the cord is combined into a drive unit with the electric motor (12) and connected thereto by a transmission device, which is influenced by a braking force, means being provided for stopping the electric motor in response to suspension of the tension in the cord (4) caused by the movement in said other direction effected by the spring force, when dewinding the cord, said stopping me
