Abstract: In a teletext system, in order to be able to "thumb through" the programme summaries of several days of transmission without making considerable investments in the teletext decoders on the recipient side, it is proposed to submit in the form of a tabulation on one separate page of teletext the page numbers of the total quantity of teletext pages in a repetition cycle or in a part of the latter, and to insert them in an intermediate memory on the recipient side. If the user has selected a precise teletext page, a check is made by comparing, with the page numbers inserted in the intermediate memory, whether the desired number of the teletext page figures in the cycle or in a part of the latter, after which said page is looked for if necessary. Furthermore, the decoder automatically checks on the basis of the number of the desired teletext page, and comparing again with the page numbers in the intermediate memory, whether the numbers of the following teletext pages figure in the cycle or in a part of the latter, after which a search is made for the following pages identified as figuring in said cycle, which are inserted in the intermediate memory and reproduced upon a special instruction from the user.

Abstract: Tensioning and lashing device for the stepwise tensioning and stepless release of lashing lines, consisting of a bracket (1), of a pivoting arm (2) and of a ratchet mechanism which is composed of ratchet wheels (3, 3') and blocking slides (5, 5'). Because a plurality of blocking slides (5, 5') is used, a higher lashing force can be absorbed or a stepwise tensioning of the lashing line in blocking-step sizes different from the tooth division t is possible. To release the lashing line, there is formed on the pivoting arm (2) a control cam (40) which brings the blocking slides (5, 5') into a disengaged position and consequently the ratchet mechanism into a release position. The use of curved blocking slides (5, 5'), of a curved driving slide (20) and of a leg spring (41) as a single spring element for the blocking slides (5, 5') allows a reduction in the constructional height of the device and has the effect of saving components and space. <IMAGE>

Abstract: A method and apparatus for manufacturing a superconductor wire has a wire take-up spool and a feed speed control spool.      A wire substrate is taken from the feed speed control spool and onto the take-up spool as the wire take-up spool is rotated. The wire passes through a container which holds a diffusion barrier material, where the diffusion barrier material is electrophoretically deposited onto the wire substrate and subsequently sintered. The wire is also passed through a container which holds a superconductor material suspended in solution, and a layer of the superconductor material is electrophoretically deposited onto the diffusion barrier. The grains of the superconductor layer are then magnetically aligned and sintered. Also, a silver coating is electrophoretically deposited onto the superconductor layer and sintered. A diffusion bonding inhibitor material is then applied to the silver coating. Then, the silver-coated superconductor wire is spooled and heated to four hundred degrees centigrade (400°C) for one (1) day to oxidize the superconductor layer.

Abstract: Each fiber-optic gyroscope unit is shaped like a tet-ragonal cone.    A square  plate (51) is used as a base which holds a light source module (52), a light receiving unit (detec-tor) (53) and an optical fiber coil (54).   Directional couplers (56) are also mounted on the base (51).   A phase modulator (55) which includes a piezoelectric element is disposed inside the optical fiber coil (54).   A signal processing circuit board (58) which has pedestals (59) stands on the base (51)  such that it positions above the optical fiber coil (54).   A polarizer (510) is wound around the optical fiber coil (54).    A reinforcement member (511)  is also provided.   All these components are so arranged as not to extend out of the tetragonal cone  (OABCO*) which defines its own unit  region.    Three  identical  fiber-optic  gyroscope units are combined by connecting members (512, 513, 514) to form a single fiber-optic gyroscope to detect rota-tional angular velocities about three orthogonal axes.    Since identical units (50) are used, the assembly is easy, and since the three units (50) are combined with respect to the axis of symmetry, the combined units (50) form a compact gyroscope.
