Patent ES-426963-A1 (ES)
Title: System for transferring wideband sound signals
IPC: H04B1/66
Filed: 1974-06-04
Abstract: A system for transmitting wideband signals, for example speech, over a narrow band is proposed. Lower frequency range signals are directly transmitted and amplitude information of partial upper frequency ranges is transmitted on pilot frequencies. At a receiver, "equivalent" signals from oscillators having frequencies approximately equal to the mid range frequencies of the partial upper frequency ranges are modulated with the amplitude information of the corresponding partial upper frequency ranges to produce "synthetic" signals. The synthetic signals are modulated with narrow band noise to crreate a more pleasing and realistic sound. Means are provided for controlling at the pick-up end the "modulation factor" of the noise modulation at the reproducing end. This is achieved by controlling the level of the third harmonic of a sync signal transmitted from the pick-up end. The level of the third harmonic may be automatically or manually adjusted to conform to the type of sound being transmitted.

Title: Drive system, particularly for ships
IPC: B63J3/02
Filed: 1975-01-24
Abstract: The drive system includes a motor or engine whose output shaft is connected to the input shaft of a transmission, e.g. speed reducing gear, via an elastic coupling and a clutch, in that order. The input element of the coupling sits directly on the motor or engine shaft the output element (ring) of the coupling is suspended in cardan fashion, possibly together with the input element of the clutch, by means of an additional elastic coupling which has one part secured to the clutch input and the other part is connected either to a bell shaped structure which is journalled in the transmission casing or to the output element of the motor coupled coupling. The two parts of the additional coupling are interconnected through annularly arranged elastic sleeves. The bell shaped structure can be used in either case, and extends from a hollow shaft being traversed by the transmission shaft and driving auxiliary equipment independantly from the operational state of the clutch.
Patent ES-438422-A1 (ES)
Title: Antibiotic a-28086 and process for production thereof
IPC: A23K20/195
Filed: 1975-06-10
Abstract: The novel antibiotic A-28086 complex containing the factors A, B and D is produced by culturing Streptomyces aureofaciens NRRL 5758 or Streptomyces aureofaciens NRRL 8092 in a culture medium, which contains assimilable sources for carbohydrate, nitrogen and inorganic salts, in submerged aerobic fermentation conditions until these organisms have produced a significant amount of antibiotic activity in the culture medium. The antibiotic is then separated off from the culture medium. The novel antibiotic can be dissociated into the factors A, B and D. These can be converted into the corresponding physiologically tolerated salts. The novel antibiotic can likewise be converted into C2-C6-acyl esters. The novel antibiotic A-28086 complex, the factors A, B and D, the physiologically tolerated salts thereof and also C2-C6-acyl esters thereof are used to increase the feed intake of ruminants. They can additionally be used for the prevention or treatment of coccidiosis in poultry.

Title: Process for the rapid, continuous and waterless dyeing of textile and plastic materials
IPC: D06P1/92
Filed: 1977-01-05
Abstract: A process is disclosed for the rapid, continuous and waterless dyeing of textile and plastic materials in which the dyestuff is dissolved, suspended or dispersed in a high boiling solvent, such as glycol or glycol ether, for carrying out the dyeing step per se, after which the dyed textile or plastic material (after cooling if desired) is subjected to a washing with a low boiling liquid such as methanol or ethanol (preferably the former) or a chlorinated hydrocarbon solvent, and subsequently dried. The entire series of operations is carried out under nonaqueous or substantially nonaqueous conditions with the complete or substantially complete recovery and recycling of the used dyestuff, the used high boiling solvent, and the used low boiling wash liquid. In this way the entire operation is conducted in a relatively inexpensive fashion and in a completely or substantially completely closed cyclic system with essentially complete recovery and reuse of the treating liquids so that not only is the cost of the overall operation greatly minimized, but also without any need for pollution of natural water resources such as rivers and wells such as has in the past taken place to a more or less serious extent where effluents of a substantially aqueous nature but containing serious amounts of polluting substances were discharged into rivers and the like thereby creating environmental problems.

Patent ES-461387-A1 (ES)
Title: Energy storage and retrieval as heat
IPC: F24D11/00
Filed: 1977-08-05
Abstract: Energy is stored by heating a salt to a temperature above its latent heat of fusion to convert the salt to a liquid state. Heat is retrieved by moving a heat transfer fluid that is immiscible with the salt and has a density less than that of the salt over the top surface of the liquid salt at such a velocity that the upper layer of the salt is emulsified with the heat transfer fluid to crystalize the salt in the upper layer. Heat is thereby exothermally surrendered to the heat transfer fluid and the crystalized salt gravitates from said top surface, thereby maintaining the top surface in a liquid state. It is preferred to move the heat transfer fluid over the top surface of the salt in either a vortex pattern, or an outward radial pattern.

Patent ES-467218-A1 (ES)
Title: Nuclear reactor
IPC: G21C7/08
Filed: 1978-02-22
Abstract: In the water-cooled nuclear reactor, the vertically arranged control rods (50) pass through the outlet plenum (26) into the fission chamber (12), these control rods being surrounded by thimbles. A major portion of the cooling water flow is fed directly to the floor of the fission chamber (12), so that flow through the latter takes place in an upwards direction. A small portion pressurises a space (72) in the upper part of the tank and flows downwards through the rod thimbles and thus reaches the major portion of the cooling water flow in the lower part of the fission chamber. The result is to provide a cooling arrangement in which the control rod cooling is less critical with respect to the flow control and the performance in the case of an emergency shutdown of the reactor.

Title: Apparatus for desalinating water by reverse osmosis
IPC: B01D61/02
Filed: 1980-02-01
Abstract: In a reverse osmosis plant for desalinating seawater or brackish water the osmosis cell or cells (1) are located at a level sufficiently below the saline water supply (6) and the brine discharge point (8) so that the hydrostatic pressure resulting from head (2) provides the major component of the pressure at the saline side of the osmosis cell or cells needed to bring about reverse osmosis.

Patent ES-8103311-A1 (ES)
Title: Hydraulically operated transmission control
IPC: F16H61/4078
Filed: 1980-04-02
Abstract: A hydraulically operated control arrangement for a transmission includes a spring-loaded pressure regulating valve which slides into a position to cut off an exit chamber for hydraulic fluid from an input chamber for pressurized hydraulic fluid so as to route the incoming hydraulic fluid exclusively to the transmission for various control and lubricating functions when hydraulic fluid pressure in the input chamber falls below a first threshold value. Hydraulic fluid applied to the input chamber continues to feed a first plurality of functions within the transmission via the input chamber and a second plurality of functions in the transmission via an intermediate chamber disposed between the input and exit chambers and in communication with the pressure regulating valve until such time as the hydraulic fluid pressure at the input chamber drops below a second threshold value so as to permit the pressure regulating valve to cut off the intermediate chamber from the input chamber. Loss of hydraulic fluid pressure also causes movement of a power takeoff control lever to the disengaged or off position through the action of a power takeoff control valve which operates a detent arrangement and movement of a planetary control lever into a low position through the action of a high-low control valve.
