Abstract: A stator assembly for a planar electrical motor includes coil conductors arranged in a stator layer, elongated in a first direction and arranged side by side in a second direction perpendicular to the first direction. The coil conductors are connected to form a three-phase system, with a first forward conductor and first return conductor of the first phase connected in series to the first forward conductor, a second forward conductor and second return conductor of the second phase connected in series with the second forward conductor, and a third forward conductor and third return conductor of the third phase connected in series with the third forward conductor. The three-phase system has first and second opposite sides. The first forward conductor and the first return conductor are electroconductively connected in series by first and second horizontal connecting conductors arranged in the stator layer on the second and first side, respectively.

Abstract: The invention relates to a weatherstrip assembly which is used particularly for sealing a folding hardtop (10) of a motor vehicle and comprises a joint consisting of sealing section (21) and fastening section (22) parts. The sealing section (21) is provided with a sealing lip (23), which is made of elastically deformable material, can be moved from the first position (I) to the second position (II) thereof and is provided with at least one restoring element (40). In order to ensure a durable, efficient and reliable restoring response of the sealing lip (23), it is provided with a tensioning element (50) in the form of a hose on the end thereof.

Abstract: The invention relates to a lid element which is placed on cell culture vessels in which cells contained in a liquid medium are accommodated. The lid element according to the invention is intended to allow determination of metabolism activities of cells which are contained in the cell culture vessels, by means of optical measurement methods, which can be carried out with simple handling by means of laboratory personnel. Light-guiding elements are provided on the lid element which can be fitted to the cell culture vessel and, when the lid element is fitted, project into the interior of cavities in the cell vessel. At least one optically sensitive layer is formed on one end surface and/or on the outer envelope surface of the light-guiding elements, which are preferably optical waveguides in the form of rods, for detection of chemical substance concentrations which change within the cavities.

Abstract: A tape cassette, in particular a magnetic tape cassette, is provided, for tape and hub guidance, with bent support liners (7, 8) which are located between the roll (1) or rolls and the adjacent housing wall (6). According to the invention, bent-over or folded-over longitudinal strips (7a, 7b) which are bent at certain angles toward the housing wall (6) support the liners (7, 8) in such a way that it is possible to counteract deformation due to the weight of the rolls of tape. These liners (7, 8) can be used for all cassette recording media, but preferably for those having a very small tape thickness.

Abstract: In a tape cassette possessing symmetrically arranged support liners, a compressive force dependent on the tape roll diameter is exerted by the liner and utilized for centering the roll and the tape. Force/diameter relationships, and embodiments of folded liners for achieving individual forces are described. A novel dynamic liner arrangement can be used in any tape cassette possessing high winding speeds and sensitive tapes, with frequently alternating rewind/playback operation.

Abstract: A support liner (20) for a magnetic tape cassette comprises a coherent double liner whose individual liner parts (20a and 20b) are supported against the inner walls of the cassette to provide a cushioned support for tape rolls of the cassette.

Abstract: The invention provides a circuit for centrally generating the horizontal and vertical sweep frequencies in a TV receiver. A central oscillator provides a frequency which is divided to obtain the horizontal frequency. A periodic counter with adjustable final counting value divides the central oscillator frequency to establish a vertical sweep signal. Phase comparators and gate circuits are used to gate the oscillator signal to the periodic counter to synchronize the vertical sweep with the transmitted vertical sync signal.
