  • Patent number: 6715955
    Abstract: This invention relates to a fastening device for an insulating glass panel. A punctiform holder (1) is used that is fastened by means of an adhesive (51) to the outside of the insulating glass plate (50). In the vicinity of the punctiform holder (1), a spacer piece (53) is inserted between the separated glass plates (2, 50). The invention further relates to a mounting element (5) with adjustable bias, whereby between a cap bell (10) and the mounting element (5) there is a permanently elastic spring element (7) that permits a relative movement of the cap bell (10) with respect to the mounting element (5). The invention further relates to the realization of a plurality of three-dimensional articulations (12, 13) between the insulating glass plate (2, 50) and the holder on the building side.

  • Patent number: 6553238
    Abstract: Device and method for the remote diagnosis and/or remote monitoring and/or remote initialization of a microprocessor-controlled door, door system or garage door system operated by an electric motor. The microprocessor control can be connected with a data transmission device for the performance of a remote diagnosis and/or remote monitoring and/or remote initialization of the microprocessor control. The data transmission device can have a modem adapter. The modem adapter can connect the microprocessor control to a cellular telephone, which cellular telephone can be dialed through a cellular data network. The cellular telephone can also be part of the data transmission device. The data transmission device can simultaneously be effectively connected to a service center.

  • Patent number: 6510586
    Abstract: Door closer with a spring system that must be stretched when the door is open and supplies the closing moment necessary to close the door. There is provided a gear train between the spring system and the door to influence the force curve which varies over the opening angle of the door, whereby the gear train that varies in its translation ratio over the opening angle of the door has a first and a second gear wheel that mesh with each other and are each formed by a circular gear rim and are mounted eccentrically with respect to their centers while retaining the axial distance between them. The first gear wheel is connected with an output shaft and the second gear wheel is connected coaxially with respect to its center of motion with a gear wheel that is engaged in a rack that is coupled with the spring system.

  • Patent number: 6082053
    Abstract: The movable partition system has a plurality of movable partition elements placed on a horizontal rail. Each of at least two of the movable partition elements has its own electric motor. Each electric motor has a current collector connected to it which passes along at least two conductor rails which are part of the electrical circuit when the electric motor is moved. These rails are connected via lines to a control unit which controls the power supply and the operation. One conductor rail is connected with a single line. On the other hand, at least one other conductor rail has a plurality of lines which lead to electrical connections or taps which are isolated from one another by insulators. This isolation permits the control unit to control the individual flow of current to each separate tap. This makes it possible to individually control and position the individual movable partition elements.
