Patent ES-470007-A1 (ES)
Title: Digital circuitry for spark timing and exhaust gas recirculation control
IPC: F02D21/08
Filed: 1978-05-18
Abstract: A digital signal processing circuit for controlling the spark timing and exhaust gas recirculation (EGR) of an internal combustion engine is disclosed herein. The circuit first samples the magnitude of the vacuum manifold pressure and produces a complex function analog output signal in response thereto. The output signal is produced by first converting the vacuum pressure to a digital signal, then using a read only memory to produce a complex function digital output signal and then reconverting the digital output signal to an analog output signal. The pressure analog output signal is then stored in a first holding device. Subsequently, an analog signal proportional to the period of engine revolution is sampled by the same circuit. However, the circuit now develops a digital output signal which is a function of the inverse of this analog input signal and this inverse digital output signal is effectively multiplied by the held pressure analog signal to produce an EGR analog control voltage which is stored in a second holding device. Subsequently, an analog output signal which is a different inverse function of the engine period is developed and stored in the first holding device and then the EGR analog output signal is processed by the circuit and effectively multiplied by the analog signal now being held in the first holding device to produce a spark timing control analog output signal which is stored in a third holding device. The EGR control signal in the second holding device controls how much exhaust gas will be reinjected into the cylinders of the internal combustion engine and the spark timing control signal in the second holding device adjusts the timing of the sparks generated for the cylinders of the internal combustion engine.

Title: Monocalcium Phosphate and Phosphoric Acid Production
IPC: C01B33/10
Filed: 1979-05-14
Abstract: Monocalcium phosphate, phosphoric acid and/or potassium phosphate containing fertilizers are produced in a process involving acidulation of phosphate rock with phosphoric acid in the presence of added silicon dioxide and potassium ion whereby fluorides contained in the rock are converted to K2SiF6 and monocalcium phosphate dissolved in phosphoric acid is formed during acidulation. In an important feature, the K2SiF6 is separated and hydrolyzed to regenerate the K2O from K2SiF6 recycled KH2PO4/H3PO4 solution for further reaction with fluoride from fresh phosphate rock feed. A portion of the MCP/H3PO4 solution and/or crystallized monocalcium phosphate can then be reacted with potassium sulphate, potassium bisulphate, or mixtures thereof to form KH2PO4, or KH2PO4/H3PO4, solutions, and gypsum. In a closely related embodiment, the remaining MCP/H3PO4 solution is reacted with sulphuric acid to produce phosphoric acid product and/or the recycle phosphoric acid required in the phosphate rock acidulation step.

IPC: F02B37/16
Filed: 1980-01-31
Abstract: An internal combustion engine has a turbo-supercharger connected to an engine charge air intake manifold and an exhaust gas turbine connected to an engine exhaust manifold. An automatic bypass includes a bypass line interconnecting the exhaust manifold upstream of the exhaust gas turbine and the air intake manifold downstream of the compressor.

Title: Production of a selectively protected N-acylated derivative of an aminoglycosidic antibiotic
IPC: C07H23/00
Filed: 1980-06-16
Abstract: Aminoglycosidic antibiotic comprising a 6-0-(3''-aminoglycosyl)-2-deoxystreptamine optionally having a 4-0-(aminogycosyl) group, such as kanamycins, gentamicins, sisomicin, forms reversible complex with zinc cations by association of the zinc cations with some pairs of aminohydroxyl groups in the aminoglycoside, and the zinc-complexed amino groups are blocked from acylation. Reaction of this zinc complex with an acylation reagent having an amino-blocking acyl group brings about acylation of the non-complexed amino groups to give an N-acylated zinc complex, namely a complex of zinc cation with an N-acylated aminoglycosidic antibiotic derivative. Removal of zinc cations from N-acylated zinc complex yields a partially N-acylated aminoglycosidic antibiotic where 1- and 3''-amino groups are unprotected but all other amino groups protected with acyl group. Further reaction of this partially N-acylated product with a certain alkanoic acid or N-formyl-imidazole results in preferential acylation of 3''-amino group without 1-amino group being acylated, affording a 1-N-unprotected and other N-fully-protected derivative of the aminoglycosidic antibiotic which is valuable to be 1-N-acylated with alpha -hydroxy- omega -aminoalkanoic acid for high-yield production of known semi-synthetic 1-N-( alpha -hydroxy- omega -aminoalkanoyl)-aminoglycosidic antibiotic.

Patent ES-8106620-A1 (ES)
Title: Secure data processing device.
IPC: G06F11/14
Filed: 1980-09-26
Abstract: The invention relates to a secure data processing system having processors processing the same information items in at least two channels and being controlled step by step. The invention consists in the fact that each channel contains a BUS line. To each BUS line an independently operating microprocessor, a read/write memory, a read-only memory, a past-memory chip, a parallel output and a serial data output circuit are connected. The BUS lines are connected to one another by a failsafe co-ordination unit which controls the acceptance and outputting of the information items. Parallel or serial information items or those already protected can be optionally entered. Protected parallel or serial information items can be optionally output. It is only the co-ordination unit, the comparators, the clock and synchronisation unit and the bit-parallel or bit-serial output in the data output circuits which are secure modules. Each microprocessor is independently controlled by itself. After the arrival of the results of the comparison, the co-ordination unit outputs an instruction for processing the next program step or for repeating the program step or for stopping. The channels are of modular construction. Several of these security output circuits can be connected to form one multiprocessing system.

Title: Container for radioactive wastes.
IPC: G21F9/36
Filed: 1983-04-22
Abstract: The invention is directed to a container for storing radioactive materials such as irradiated nuclear reactor fuel elements and the like. The vessel of the container is configured to have a plurality of wall layers. The inner wall layer of the vessel consists of a mechanically stable inexpensive metal material which is surrounded by a corrosion-protective wall layer made of high-alloy austenitic castable material with nodular graphite. The receiving opening of the vessel is closed by a sealing cover welded to the corrosion-protective layer. The container serves not only as a container for the final storage, it also can be utilized for a long-term storage at a surface location as well as for transport of the irradiated fuel elements. The amount of material needed for the corrosion-protective layer is held as low as possible. This is achieved by casting a wall layer of cast iron containing nodular graphite in surrounding relationship to the corrosion-resistant wall layer. The thickness of this outer wall layer is selected to afford the required shielding effect.
