Abstract: A method of making a ribbon-like or sheet-like superconducting composite body is disclosed. The method is well suited for making long lengths (e.g., >100m) of ribbon or large areas (e.g., > 100cm²) of sheet-like composite. The method comprises forming a Bi-Sr-Ca-Cu-oxide-containing layer on a metal (exemplarily Ag) substrate, and mechanically deforming (typically by rolling) the thus formed composite such that the oxide is densified to more than 80% of the theoretical density. Subsequently the oxide layer is at least partially melted and allowed to re-solidify such that a large portion of the oxide crystals has c-axis alignment. After appropriate heat treatment in an O₂-containing atmosphere, thus produced superconductor ribbons or sheets can have high J c  (≧10⁴, frequently > 10⁵ A/cm²) for temperatures less than about 20K and in magnetic fields less than about 5T.

Abstract: A resin composition comprises 100 parts by weight of a polypropylene and 20 to 100 parts by weight of a hydrogenated styrene/butadiene or styrene/isoprene elastomeric block copolymer having a melt index of not less than 25 g/10 min as determined at a temperature of 230°C and a load of 2.16 kg/cm². A method of manufacturing a coated molded article of the resin composition comprises the steps of molding said resin composition and then applying a coating directly thereto without any preliminary surface treatment. This method can yield a molded article having a low mold shrinkage factor and linear expansion coefficient, and the amount of fillers to be incorporated can be reduced thus saving weight.

Abstract: With some bidirectional transmissions use is made of differential links (L, L<*>) and transceivers (1) which provide differential measurement signals (V, V<*>) representing signals transmitted from a distant station. To reduce consumption, the electrical supply to the transceivers (1) can be interrupted during periods of inactivity. The method consists in determining a threshold value of value intermediate between the maximum and minimum values which can be taken by the measurement signals (V, V<*>) and in providing a transmission activity signal (VAL) resulting from the comparison between the measurement signals (V, V<*>) and the threshold value. The implementation circuit uses voltage comparators and can be an integrated circuit. Application in particular to the interconnection between the units of a computer system. <IMAGE>

Abstract: The process for treatment of spent aqueous solutions of caustic soda used for purification and washing of petroleum-products is based on the synergical use of ozone and calcium hypochlorite. More specifically, the process according to the present invention consists essentially in subjecting the spent aqueous solutions of caustic soda to the following operations:
     a first oxidization using 0,5-3,5 Kg of O 3 /Kg of total phenols, at a temperature of between 38 and 42°C;   a second oxidation with 5-10% by weight of calcium hypochlorite, referred to the previously ozonized spent caustic soda, at a temperature selected from the range of between 25 and 35°C, with the formation of a pulp with a flaky suspension; and   separation of the pulp formed into a liquid phase and a solid phase, each of which can be eliminated in a much easier and safer way, from an ecological point of view, than the initial spent solution of caustic soda.

Abstract: Anti-reverse mechanism for a rail track, having a rack (32), fixedly connected to the track body, and a ratchet pawl (2) fitted on a rail vehicle. The ratchet pawl (2) has a ratchet tooth (21) which is designed for engagement into the rack (32). The ratchet pawl (2) is in frictionally locking connection with a friction disc (3) following the rotational direction of the running wheels. The rotational movement of the ratchet pawl (2) is restricted by a stop (25). An essential feature of the invention is that, owing to the frictionally locking connection between ratchet pawl (2) and friction disc (3), the ratchet tooth (21) is raised above the toothing of the rack (32) during travel in the normal direction. Aggravating sound development is thus avoided. When in use, the ratchet tooth (21) of the ratchet pawl (2) moves into the toothing of the rack (32), owing to the frictionally locking connection, and thus prevents the vehicle from rolling backwards. <IMAGE>

Abstract: A digital data processing apparatus includes two functional units (40, 50) and a controller (10) for transferring information between them. Each of the functional units includes an associated memory element, (43, 53) such as a random access main memory. The first functional unit includes a sender element (41) that generates a send message descriptor block ("MDB") signal specifying one or more addresses in the associated memory means (43) from which data is to be transferred. The controller (10) identifies a send MDB signal that matches a selected receive MDB signal to generate a signal to effect the transfer of data between the respective memory locations (43, 53) of the first and second functional units (40, 50) specified by the matching MDB signals. A data transfer element (30) within the controller (10) responds to that transfer-effecting signals by (i) applying to the memory (43) of the first functional unit (40) an address signal representative of addresses specified in the send MDB signal and receiving therefrom data signals generated thereby in response to application of that address signal, and (ii) applying those data signals to the memory means (53) of said second functional unit, (50) along with an address signal representative of addresses specified in said receive MDB signal.
