Patent ES-392199-A1 (ES)
Title: Tdm telecommunication system for transmitting data or telegraphic signals
IPC: H04J3/16
Filed: 1971-06-02
Abstract: At a multiplexing terminal of a telecommunication channel, a plurality of access units form composite words from interleaved bits or multibit characters of messages concurrently received over respective groups of incoming lines, the bits emanating from each access unit having a cadence mi vo individual to that unit. A switching circuit cyclically samples a set of group registers in which the words from the respective access units are at least partially stored, thereby establishing a frame which consists of a sequence of mi bits from each unit along with address bits and supplemental bits. A frame counter at the multiplexing terminal determines the completion of a superframe composed of a predetermined number of frames so chosen that all the words are restarted in their original time position within the first frame of each new superframe. An associated demultiplexing terminal comprises a similar switching circuit which directs the individual bit sequences of each frame to respective distributing units while another frame counter establishes the instants at which a word allocated to any distributing unit starts and ends, thereby enabling that unit to divide the word into its constituent characters for retransmission over corresponding outgoing lines. Synchronization of the counters at the two stations is facilitated by the periodic substitution of a special code for the address bits of a frame, the frames so marked recurring a whole number of times within each superframe.

Patent ES-415969-A1 (ES)
Title: Pulse transmitter for transmission line
IPC: H04Q3/54
Filed: 1973-06-15
Abstract: A pulse transmitter is coupled to the transmission line through a pulse transformer, and at the end of a produced pulse, there occurs in the transformer a reverse voltage peak due to the fact that the magnetizing transformer current does not instantaneously vary when switched. The magnetizing current decreases and must be nulled before the generation of the next pulse. According to the invention, the reverse peak is utilized for accelerating such a magnetic current decrease, by diminishing the transformer damping.

Title: Arrangement for improving the reproduction of amplitude jumps during transmission using differential pulse code modulation
IPC: H03M3/04
Filed: 1974-11-07
Abstract: An arrangement incorporated in a DPCM code communication system to be able to reproduce steep amplitude jumps (edge between black and white) correctly. At the receiver the maximum difference value code words transmitted are added up and delivered with a shortened delay. At the transmitter, a check is made, in case of amplitude jumps, to determine how often the maximum difference value code word is transmitted. A predetermined code word is transmitted to the receiver to end the addition in the receiver when the check in the transmitter indicates that a code word other than a maximum difference value code word is to be transmitted.

Title: Process for batch production of sponge iron
IPC: C22B5/12
Filed: 1975-04-28
Abstract: Sponge iron is produced by a process including a charging step during which an iron oxide is arranged as a stationary bed in a furnace chamber, a heating step during which a hot, preferably non-reducing atmosphere is cased to flow through the stationary bed, and a reduction step during which a hot reducing atmosphere is caused to flow through the stationary bed to reduce the iron oxide to sponge iron. Optionally, there is a final cooling step during which cold non-oxidizing atmosphere cools the sponge iron. The relatively hot atmosphere which has just passed through the stationary bed is counter-currently heat exchanged with the relatively cool fresh atmosphere about to enter the furnace chamber.

Patent ES-460169-A1 (ES)
Title: Object position and surface determining methods and apparatus
IPC: G01S17/32
Filed: 1977-06-28
Abstract: The position determining device (10) exhibits a mask (16) which can be displaced along an axis (T) located in the reference plane. A light source (20) can be displaced together with the mask (16). A sequence of photocells (26) with a lens (26a) contains photocells (PC1-PC7). The mask (16) contains transparent sections and opaque sections. Planes (P1, P2, P3), in which the radiation-reflecting objects (O1, O2, O3) are located extend in parallel with the said axis (T). The time required by the radiation pattern to pass over a location in the planes (P1, P2, P3) is a measure of the distances (x1, x2, x3). When light source (20) and mask (16) are displaced, the objects (O1 - O3) are successively irradiated by light, with intermediate periods without radiation. During the displacement of the pattern, the sequence of photocells (26) detects an energy reflection by the objects (O1 - O3). An output signal is generated at the rate of the pulse repetition rate and is processed in order to establish the object distance.

Title: Process for the production of synthesis gas
IPC: C10G9/36
Filed: 1978-03-07
Abstract: A process starting from a hydrocarbon feedstock, and aiming to produce a synthesis gas suitable either for methanol synthesis or for other applications requiring a low H2/CO ratio. In this process, the feedstock, supposed to be desulfurized, is divided into two fractions a first fraction undergoes a primary steam reforming at high pressure and moderate temperature the gas effluent from said primary steam reforming, as well as the second fraction of the feedstock, are combined and subsequently undergo a secondary reforming by reaction with an oxygen-containing gas in a reactor operating under essentially adiabatic conditions. The synthesis gas, obtained as effluent from said secondary reforming, has a composition adjustable at will in a wide range, and therefore can be made as close as necessary to the stoichiometric composition required for methanol synthesis, or it can be made with a low H2/CO ratio for other applications. The synthesis gas is available at high pressure, and can therefore feed directly, without compression, the synthesis loops downstream. The process of the present invention is particularly suitable for methanol production on a very large scale.
