Patent ES-8507284-A1 (ES)
Title: Primary circuit pressure-control method during the shut-down period of a pressurised water nuclear reactor.
IPC: G21C1/09
Filed: 1981-05-13
Abstract: Method for regulating the pressure of the primary circuit of a pressurized water nuclear reactor during shut-down phases, by use of an installation comprising, as a branch circuit to the primary circuit, a volume control circuit with a discharge valve and a charging valve. When the liquid level in the pressurizer approaches the top, a constant flow rate is maintained at the charging valve, the flow rate of the discharge valve is regulated by direct measurement of the primary pressure, successive sprinklings through the valve follow and the reduction in discharge flow rate is detected until further sprinkling has no further effect on the discharge flow rate.

Patent ES-8301561-A1 (ES)
Title: Method and apparatus for transmitting a digital signal
IPC: G11B20/18
Filed: 1981-08-11
Abstract: A PCM digital signal is provided with double-interleaving and error-correction encoding to protect against errors occurring during transmission, which can be carried out by magnetic recording and reproducing. The PCM signal is processed as error correcting blocks of several data word sequences and an associated error correction word sequence, and the double-interleaved sequences are then transmitted as transmission blocks. Up to one erroneous word in each error correction block can be corrected by using the error correction word sequence. Any uncorrectable word can be compensated by substituting a synthetic word interpolated from immediately preceding and following data words known to be correct. The distance between successive data words is made as great as possible so that a long burst error is unlikely to affect the ability to compensate uncorrectable errors. To achieve this, alternate words of the PCM signal are distributed to odd and even groups of sequences, and the interleaving is carried out by imparting different delay times to the respective sequences such that the greatest delay time imparted to the odd sequences is less than the shortest delay time imparted to the even sequences. The error correction word sequence is provided with a delay time intermediate the greatest delay time of the odd sequences and the shortest delay time of the even sequences.

Patent ES-8304440-A1 (ES)
Title: Reciprocating dialyzer having spacers.
IPC: A61M1/22
Filed: 1981-11-04
Abstract: A reciprocating dialyzer is described for use as an artificial kidney or other extracorporeal mass transfer device. A dialyzer unit includes a membrane package having an aligned pair of thin semi-permeable membranes forming a chamber between the interior faces to receive fluid (such as blood) to be treated, and spacing elements in dialysate chambers at the exterior faces of the membranes which contact the membranes and limit their expansion, while allowing chemical transfer to the dialysate slurry. A plurality of such treatment units received between spaced plates comprises a dialyzer. Blood flow into and out of the membrane packages is through a central conduit, with free slurry being introduced and withdrawn from the dialysate chamber at the periphery of each unit. The spacing elements are flexible and of plastic with mesh material modified to provide central and rim seals as well as membrane engaging faces designed to limit membrane displacement and cause formation of a thin blood column while not unduly masking the membrane surfaces and allowing slurry flow at all times including when the blood chamber is filled with blood. Certain spacing elements also allow emptying of blood from the dialyzer without need for positive pressure on the fluid outside the dialyzer.
Patent ES-8308177-A1 (ES)
Title: Digital repeater circuit.
IPC: H04B3/36
Filed: 1982-05-29
Abstract: Feedback equalization is employed for digital repeaters of transmission systems having twisted-wire pairs, in order to reduce intersymbol interference while minimizing near-end crosstalk gain. Previously the incoming signal was selectively amplified at the higher frequencies in order to negate intersymbol interference, with subsequent near-end crosstalk gain. According to the present invention the intersymbol interference element of an incoming signal is cancelled, prior to amplification in an adder by a compensation signal derived from the output signal of a regenerator and a retimer. An output stage serves to amplify and shape the resultant signal to a form suitable for transmission. The compensation signal comprises the inverted output of a filtering and scaling network.

Title: Method and apparatus for comminuting stumps
IPC: B27L11/00
Filed: 1983-01-25
Abstract: The invention is directed to a method and apparatus for comminuting stumps. The apparatus includes a generally cylindrical stationary drum having a feed opening in the upper portion through which stumps are fed to the drum. A rotatable substantially horizontal bottom encloses the lower end of the drum and is disposed to rotate about a vertical axis so that the stumps are forced to the outer periphery of the drum under centrifugal force and revolve along with the bottom. An abutment or counter member extending upwardly from the bottom and the stumps are braced against the countermember as they are moved into engagement with a generally cured vertically disposed blade that is spaced inwardly of the drum. The blade acts to comminute the stump and the chips or particles are discharged from the drum through a discharge opening which is disposed radially outward of the blade. The chips are fed into a cleaning drum and subsequently into a separating member where the rejected fraction of the chips is recirculated back to the drum. Detached soil can be removed from the feed drum through discharge peripheral apertures in the bottom, or through the gap between the cylindrical drum and the rotating bottom.
