Title: Method and apparatus for efficiently producing cellulosic pulp by the thermo-mechanical pulping method.
IPC: D21B1/14
Filed: 1981-02-14
Abstract: Method and apparatus for producing cellulosic pulp by the thermo-mechanical pulping method wherein wood chips are contacted with gaseous steam at a temperature and for a time sufficient to bring the temperature of the chips close to that of the steam, compacting the resulting steam treated chips while mechanically conveying the same to reduce the moisture content and produce a compacted moist mass, shredding the compacted mass while further conveying the same under more severe conditions than the original conveying and then passing the shredded mass into a refiner. The apparatus of the present invention preferably takes the form of a pair of coaxially operating worm-type conveyors with the end of one conveyor being journalled in the end of the other, and operating under conditions such that the second conveyor tends to pull the compacted mass faster than it is being delivered and thereby provides a shredding action to maintain a fairly uniform input into the refiner stage.

Patent ES-8403260-A1 (ES)
Title: Error correction method for the transfer of blocks of data bits, a device for performing such a method, a decoder for use with such a method, and a device comprising such a decoder.
IPC: G11B5/09
Filed: 1983-01-19
Abstract: For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator. Invalid channel words are provided with an invalidity bit in the demodulator. During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways. When too many words of a group of code words are invalid, all words of the relevant group are invalidated. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words.
Patent ES-8406972-A1 (ES)
Title: Apparatus and method for tipping cargo containers
IPC: B66C1/66
Filed: 1983-04-16
Abstract: A tipping adapter permits a cargo container, which is suspended from a hoisting device, such as a gantry cantilever crane, to be selectively tipped about an axis extending longitudinally through the container so that bulk material, such as coal, grain, etc., may be tipped from the container into a ship's hold or other receiving space. The adapter includes a drive support frame which connects to the crane or a crane-supported container spreader at the connection points normally used in connecting the container to the spreader. A pivotal frame connects to a container in the same manner in which the spreader connects to the container. The drive support and pivotal frames are pivotally engaged so that one or more drive motors, mounted on the drive support frame, can be used to selectively pivot the pivotal frame and thereby tip the container. Controls are placed at the crane control panel to permit selective container engagement and tipping, and interlocks are provided to prevent tipping of the container before it is properly engaged.

Title: Method and system for interconnecting synchronous or asynchronous three-phase networks by means of variable reative impedances.
IPC: H02J3/24
Filed: 1984-06-08
Abstract: A method and a system for interconnecting two electrical, alternating three phase networks operating asynchronously or synchronously at voltages of equal or adjacent frequencies, and in which, for corresponding phases, the voltages of the first and second networks are out of phase by a constant or varying angle. A plurality of three phase variable reactive impedances interconnect the two networks for carrying out a desired transfer of active power from one of the two networks to the other. The variable impedances are operated to establish between each phase of the first network and the three phases of the second network, three interconnections each having a different susceptance, which susceptances vary with the three phase variable reactive impedances. A regulator measures electrical parameters associated with at least one corresponding phase of the first and second networks, and operates the three phase variable reactive impedances to vary the susceptances of the interconnections in relation with the measured parameters so as to establish the desired transfer of active power from one of the first and second networks to the other network, while maintaining at a desired level a reactive power engaged in the transfer of active power.
