Patent DE-4334361-A1 (DE)
Title: Rope and cable cutters
Inventor: HOFMANN HORST
IPC: H02G1/00
Filed: 1993-10-08
Abstract: The invention relates to a pair of rope and cable cutters having a fixed shearing knife which supports a first cutting edge and having a movable shearing knife which is rotatably mounted on the former knife, is provided on its outer edge with a toothing and on its inner edge with a second cutting edge and is driven by a pivot lifting drive via a driving ratchet. The solution according to the invention provides for preselectable and changeable transmission between the driving pawl and the movable shearing knife via switching steps which are larger or smaller than the spacing between the teeth of the movable shearing knife and in addition by arranging and supporting the driving pawl in a grid-like manner so that the lever arm on the drive lever can be modified. Furthermore, the solution provides for a reduction and improved division of the force required by dividing the cutting action between the shearing knife cutting edges.

Title: Electromagnetic high speed drive for rail vehicles and ships
Inventor: RZYTTKA MARTIN K
IPC: B60L13/03
Filed: 1993-12-28
Abstract: The electromagnetic drive comprises magnets (1) mounted in the base of the vehicle drive unit on the chassis above the rails for rail vehicles, and mounted under the top of the bow for ships. In both cases, the magnets can be swivelled horizontally and vertically, and all magnets on a vehicle are arranged to have the same degree of swivel and magnetic strength. The vehicle magnets provide an electromagnetic plus pole when energised, with the electromagnetic minus pole provided by the rail for rail-borne vehicles and by water for ships. Vehicle electromagnets are energised only after the vehicle has been accelerated to a predetermined speed by a conventional drive method, and the original drive method is restored if the speed returns below the predetermined value.

Title: Method for measuring optical attenuation
Inventor: TAKEUCHI NOBUAKI
IPC: G01M11/00
Filed: 1994-01-28
Abstract: The optical reflector plates 11, 12 and 13 are fitted on the end of the fibre-optic cables 8, 9 and 10, respectively. An optical waveguide directional coupler 2, which has at least one common terminal A and at least two output terminals B and C, is located between an optical time-domain reflectometer 1 (OTDR) and the fibre-optic measuring cable 5. The output terminal B is connected to one end of the fibre-optic cable 6 and the output terminal C is connected to an optical reflector plate 4 via an optical variable attenuator 5, the attenuator being able to alter the optical attenuation of light passing through. The OTDR 1 emits a pulse of light to the common input terminal A and measures the optical attenuation of the fibre-optic measuring cable 5 by determining the differences in the intensity of the reflected light pulses which are reflected at the respective optical reflector plates 4, 11, 12 and 13. <IMAGE>

Title: Analogue=to=digital and digital=to=analogue conversion using successive approximation
Inventor: BOECK HARRY
IPC: H03M1/46
Filed: 1994-08-31
Abstract: In addition to direct analogue to digital and digital to analogue conversion, the method involves value conversion by means of pseudo division and/or pseudo multiplication. It also makes use of a redundant and error tolerant, in the environment of the redundancy, graduation of values in the analogue to digital convertor used. The method involves a continuous measurement by opposing measurement of pairs of digital to analogue convertors with respect to their individual lowest value unit. This is followed by scaling to an external reference value with simultaneous use of two digital to analogue convertors per data channel pair. The digital to analogue convertor used preferably has a value graduation which is less than the decision range per individual digital to analogue convertor element.
