Title: Echo sounder with optical fibres - has optical fibre as pancake coil on flat support, related to wavelength of pressure variations
Inventor: SEPP GUENTHER DIPL PHYS DR
IPC: G01H9/00
Filed: 1980-11-13
Abstract: The echo sounder measures pressure variation measuring in a liquid. Its optical fibre receives coherent light, and the light phase shift is measured after passing through the optical fibre (9). The latter is in the form of a paucelic coil. Pref. the optical fibre coil is mounted on, or in, a flat support (14). The length or thickness of the coil is less than the highest half-wavelength of the pressure variations to be measured. The coil turns may be embedded in an elastic substance, having a lower modulus of elasticity than the optical fibre. The material of the optical fibre may have a large transit time dispersion. A single-mode waveguide may form the fibre core surrounded by a fibre layer of refractive profile of a gradient fibre.

Title: Cutting device preferably for installation in shear (scissors)-type tools for variable-cut use
Inventor: WESTHEIMER HEINZ-JOSEF
IPC: H02G1/00
Filed: 1981-02-17
Abstract: The invention relates to a device for holding, guiding and separating goods in the form of threads, such as cables, lines and hoses. There are hand-held cutting devices which conform with the prior art and separate the material which is to be cut by means of a reciprocating movement of the pair of cutters. These solutions have the disadvantage that, in the case of relatively large cross-sections of the material to be cut and a small geometrical dimension of the tool, considerable forces must be applied during the cutting process, while tools having relatively large dimensions exacerbate transportation and handling. The object of the invention is to overcome the previously described disadvantages and at the same time to achieve a greater range of use and hence a solution which conforms with practice and is economical. This is achieved according to the invention in that the cutting device is formed from a cutter lower part (which is preferably constructed rounded) and a moving cutting upper part (which is preferably provided with a joint), which parts are connected to one another via the handle upper and lower parts, which conform with a hand-held tool. The cutting parts, which are located one above the other, permit a retaining intermediate space with a variable cutting height. The cutter lower part holder, which is integrally formed on the handle upper part, and the cutting lower part, which is connected thereto via an operating element, form a contact shoulder, which is recessed in a concave shape and guides and holds the material to be cut, preferably at the shearing level, in the direction of the material which is to be cut. The moving cutting upper part, which is preferably inclined on the side facing away from the cut, slides along the cutting lower part during the cutting process.

Title: Method for destination control
Inventor: SCHMIDT HERMANN DR ING
IPC: G05D1/02
Filed: 1981-12-18
Abstract: The method according to the invention is used for destination control of automatically-inductively track-guided rail-less vehicles, the course network of which is constructed in accordance with the multi-frequency principle. The aim of the invention consists of a material- and cost-saving method which considerably facilitates manual and automatic operation. According to the object of the invention, a method for destination control of highly intermeshed course networks is to be developed in which a minimum of additional expenditure at a sufficiently large numerical range for absolute coding of the positions of the path network can be achieved by means of appropriately combining the advantages of the prior art. According to the invention, this is achieved by the fact that, in addition to a known magnetic arrangement, characteristic travelling frequencies for the relevant course section can additionally be used for evaluating and expanding the bit pattern of the magnets for coding and marking positions of a course network and an actual position can be incrementally and/or digitally absolutely detected within the course network in such a manner that the position detection in course sections between two branching points occurs incrementally and when a binary digitally absolutely coded position point which differs from the preceding code is reached, the result determined can be automatically checked and corrected by the control logic. <IMAGE>

Title: Balance of very flat design
Inventor: PUETTER PAUL STEFAN DIPL PHYS
IPC: G01G1/24
Filed: 1982-01-20
Abstract: In the construction of very flat balances, two difficulties above all have to be overcome: the measuring method must be adapted to the flat design, and a flat device for the parallel guidance of the movable plate serving for receiving the outer weight must be constructed. The invention relates to a parallel guide of very flat design. A horizontally arranged lever system is used, and in this the contact points of the levers are located in a common horizontal plane with one another and with the surrounding area. It could be demonstrated theoretically in this case that the prevailing conditions are ideal, since the frictional forces have no effect on the measurement. The parallel guide can be coupled with any measuring methods for force measurement. It can be used on balances of any load-bearing capacity and size. It can be employed for any balances in the domestic sector and the commercial sector.
