Title: Direction-finding method with a small number of spatially offset directional characteristics
Inventor: ARENS EGIDIUS DIPL ING
IPC: G01S3/80
Filed: 1988-09-27
Abstract: The frequency spectra of the group signals of the directional characteristics of a panoramic sonar system are formed and the direction determined per spectral line. In the lower frequency range, the focusing of the directional characteristics is only slight and the direction finding is inadequate, particularly to locate targets at long ranges. According to the invention, the spectral lines of all the directional characteristics at the same frequency form an angle function, as an independent variable, over the receiving direction of the directional characteristic. Their Fourier transform provides a fundamental. The phase of the fundamental is determined and indicates the direction to the target. The direction-finding method can be used advantageously in underwater sound technology at low frequencies, using a conventional cylinder base having four directional characteristics offset through 90@.

Title: Diaphragm-type carburettor with mixture enrichment when starting
Inventor: KOEHLER GISBERT DIPL ING
IPC: F02M17/04
Filed: 1989-01-12
Abstract: A description is given of a diaphragm-type carburettor with a device for enriching the air/fuel mixture with fuel during the starting of the internal combustion engine. In this diaphragm-type carburettor, the diaphragm chamber, which is normally open to atmosphere, is connected to a pulsed-pressure source, more particularly via a pressure exchanger which converts the pressure pulses from the pulsed-pressure source into a single pressure surge to open the fuel inlet valve. The diaphragm chamber is connected to atmosphere via an exhaust restrictor which relieves the pressure produced in the chamber by the pressure surge in a predetermined time. It is expedient for the cross-section of flow of the exhaust restrictor to be controllable as a function of the outside temperature. The connection of the diaphragm chamber to atmosphere, which is open during normal carburettor operation, is closed during starting by a gate valve which can be moved into its closed position by means of a manually operated actuating device and moves into its open position again when the throttle valve is actuated. The mixture enrichment device described replaces the conventional choke. <IMAGE>

Title: Superconducting oxidic ceramic material and process for producing such a ceramic material
Inventor: WUESTEFELD CLAUS DIPL CHEM
IPC: H01L39/12
Filed: 1989-05-13
Abstract: Superconducting oxidic ceramic materials having a sublattice consisting of polarisable anions are known in the form of copper oxides having the perovskite structure and also in the form of Sr2Bi2CuOx with x </= 8. The disadvantage of these compounds is that they cannot be reproducibly prepared with a high transition temperature. The invention is to provide such new materials having a higher and more reproducible transition temperature. According to the invention, such superconductors are produced using metal nitride fluorides in place of or in addition to metal oxides and the starting materials are preferably ternary in place of binary compounds. This gives either compounds whose anion sublattice is formed at least in part by nitride fluoride, such as, for example, Ba0.2La1.8Cu(N0.1F0.1O3.8), Ba0.2La1.8Cu(N1.35F 1.35O1.3)or YBa2Cu3 (N2F2O3-z) with 0 </= z </= 0.5, or subsequent driving off of the NF ions gives substances having a defined number and distribution of vacancies in the lattice, such as, in particular, in the case of Sr2Bi2CuOx with x </= 8. The transition temperature of the superconductors obtained in this way is reproducible and is generally above 100 K.
