Abstract: A drive unit for a door or a gate includes an electric motor, a detection unit for detecting the position of the door or gate, the detection unit being coupled to the motor and providing an identical pulse sequence with every rotation of the motor, wherein the duration of one pulse in the sequence is different from the duration of the other pulses in the sequence, which are equal. All detected pulses are stored in a non-volatile memory. The drive unit includes an electronic control and regulating circuit including an output stage for the electric motor and at least one memory, in which an operational program is stored providing a programmable learning procedure for an opening and closing movement of the door or gate based on the pulses provided by the detection unit.

Abstract: In the method of producing smaller, sheet glass plates having a predetermined geometry and lateral dimensions in the millimeter range from a larger sheet glass plate, a joining material is imprinted on one side of the larger sheet glass plate in accordance with a joining zone geometry of the smaller, sheet glass plates. Dividing lines along which the smaller, sheet glass plates are separated are specified on the larger sheet glass plate. Then the smaller, sheet glass plates are separated along the dividing lines together with the imprinted joining material into individual sheet glass plates.

Abstract: A door, especially a sectional door, is operated with the use of a drive unit with a drive gear, a clutch, and a position-detecting unit. The position-detecting unit detects the direction of rotation of the drive gear, detects the number of revolutions of the drive gear by pulses, and stores the pulses, taking the direction of rotation into consideration, in a nonvolatile memory. A data-processing unit is present in which different variable sequence programs are stored, which include not only safety-relevant programs but also a learning program. Reference values are determined by the position-detecting unit for a variable open position of the door, which position can be set as desired, and for a completely open position, which is limited by a stop, as well as for a closed position of the door are stored in a nonvolatile memory and are processed during automatic travel of the door.

Abstract: A lithium ion conductor having the composition Li4−xSi1−xPxO4, where x is at least 0.3 and not more than 0.7, is prepared by shaping and calcining Li4−xSi1−xPxO4, where x is at least 0.3 and not more than 0.7, and/or compounds which are converted into this during calcination, wherein the Li4−xSi1−xPxO4 and/or the compounds is/are used in the form of powder having a mean particle size of not more than 5 microns.

Abstract: Small sheet glass plates (2) of this type with a predetermined geometrical structure are conventionally produced by being cut out of a larger sheet glass plate (1). The small sheet glass plates (2) that have been separated in this way, together with a jointing cement, in particular a solder frame (3) consisting of glass solder are then attached to other components, for example to be used in “electronic packaging”. In order to improve handling during the production and the jointing of the small sheet glass plates (2), the invention provides a larger sheet glass plate (2) which is patterned on both sides using a screen-printing or stencil-printing process and preferably using laser beam treatment along desired predetermined breaking points (5). Said larger glass plate can then be separated into smaller, patterned plates, i.e. the small sheet glass plates (2), whose shape is geometrically determined, by a simple preferably mechanical breaking process.
