Title: Device and control means of the reproducing head for improving the readability of linear multi-track data recordings on measuring magnetic tape apparatuses
Inventor: STADLMANN WILFRIED DR ING
IPC: G11B5/55
Filed: 1982-11-16
Abstract: In measuring technology, multi-track measuring magnetic tape apparatuses are used for data recording and storage as mass data storage units. A high data density is required. In the case of multi-track recorders, this means a reduction in the individual track widths. The state of the art is a high tape-guidance precision. This mechanical guidance is no longer sufficient. According to the invention, the improvement in data recording and reproduction is achieved by the read head being moved in relation to the tape by a drive. With the aid of a suitable control means, the head is moved in such a way that the data tracks are read with high data integrity and typical transmission errors (time base, azimuth) are reduced.

Title: Four wheel drive for motor vehicles
Inventor: KLAUE HERMANN DR ING
IPC: B60K17/34
Filed: 1982-12-02
Abstract: A four wheel drive for motor vehicles is described which comprises a drive block with two main drive wheels and two auxiliary drive wheels. The auxiliary drive equipped with a higher transmission ratio than the main drive is provided on each side of the differential of the main drive, in each case by way of a prop shaft arranged in the longitudinal direction of the vehicle with preconnected freewheel mechanism by way of bevel gears to the appropriate auxiliary drive wheel. Under normal road conditions this solution ensures virtually the same transmission efficiency as a normal two-wheel drive. Only in the event of difficult drive conditions and the occurrence of slipping of the main drive wheels due to the transmission difference are the auxiliary drive wheels driven in addition. Utilisation of the adhesion of all vehicle wheels is automatically ensured under difficult road and weather conditions without additional differentials and at low cost. One exemplary embodiment is shown in the drawing.

Title: Two-part wedge anchorage for tendons and an apparatus with a hydraulic press for installing a fixed anchor comprising such a wedge anchorage
IPC: E04G21/12
Filed: 1983-10-28
Abstract: In a two-part wedge anchorage for tendons without a bond, a wedge-receiving hole in a wedge sleeve is sealed off with a cap. The wedge sleeve is supported on an anchor plate and receives at least one wedge for wedging the tendon. In order to achieve reliable sealing with the cap despite a geometrically simple and unweakened design of the wedge sleeve and of the anchor plate, the cap is neither screwed onto the wedge sleeve nor onto the anchor plate. On the contrary, with the exception of a widened portion at its open end, the diameter of the cap is made so small that it can be pressed onto the wedge sleeve only with a further expansion. For this purpose, the cap consists of deep-drawn sheet metal. In another embodiment, the cap can be composed of plastic with an external thread which can be screwed into a threaded sleeve which can be concreted into the structural concrete. <IMAGE>

IPC: H02H7/04
Filed: 1983-12-01
Abstract: The aim is to provide transformer protection which is intended to improve the American usages of transformer protection having power fuses. In order to be able to cut off any current which may arise in a transformer output, it is proposed to combine a switching apparatus (1) with a current-limiting fuse (2) in order to achieve effective short-circuit protection. A time-delay element (6) which is connected to a trip element (7) is driven by means of a low-voltage wrap-around converter (5), in order to provide excess-current protection. The trip element (7) operates on a mechanical drive (8) which is connected to the switching apparatus (1). A bimetallic relay (12) can also be used instead of the time-delay element (6), the make contact (13) of which bimetallic relay (12) connects a trip element (14) in parallel with two phases of said bimetallic relay (12). In consequence, a mechanical drive (15) is tripped. Both trip elements (7, 14) are trip devices of an earth-leakage current protection circuit breaker trip mechanism. <IMAGE>
