Title: Transport ship construction and method of loading floating cargo into a floatable cargo space of a ship
IPC: B63B35/42
Filed: 1973-03-14
Abstract: A transport ship for transporting floatable cargo comprises a hull having a ballast system with a plurality of ballast tanks and with at least one cargo space which is capable of being flooded. The cargo space is closed by at least one sea door. The ballast system is capable of flooding the cargo space and adjusting the ballast of the hull in order to bring the water level of the cargo space level with the surrounding sea so that the sea doors may be opened and the floatable cargo may be floated directly into the cargo space. With the method of the invention, after the vessel is ballasted and the cargo space flooded in order to adjust the level of the cargo space water to the surrounding water level the sea doors are opened and the cargo floated into the space and aligned in stowage position. The water level is then adjusted in order to either lower the cargo to position it in a secured position in which further elements are anchored to the individual cargo elements or containers or the level in the cargo space is raised even higher in order to position the cargo into an upper tier stowage position. In the upper tier stowage position hanging devices are provided for securing the cargo and/or holding it in the upper tier position. A plurality of tiers may be loaded in this manner by successively loading the vessel from the uppermost tier downwardly. Intermediate tiers are supported preferably by holding elements which are moved outwardly from the sides of the cargo space. These may comprise extendable brackets which are carried in the bulkhead walls running along the sides of the cargo space. After each whole tier length of cargo is pushed into the cargo space the sea water is adjusted to locate the cargo in a stowage position and then the cargo is secured in that position. Thereafter the level of the water in the cargo space is again adjusted and if more than one tier is to be loaded it is adjusted downwardly to float the next level or cargo in below the upper tier level. Each tier level of a cargo space is floated in along the complete length or selected parts of that cargo space at a time, and the individual cargo elements are secured in position before the adjustment of the ballasting in the cargo space is effected.

Title: Error syndrome and correction code forming devices
IPC: H03M13/19
Filed: 1974-02-19
Abstract: In information handling systems, syndrome and correction codes adapted for error signalling and correcting operations are obtained by processing words each made of a definite number of bytes, each byte having a same number of bits and one of the bytes being comprised of the parity incoming bits of the other bytes. An error syndrome and correction code forming device is described which comprises first and second stages of modulo-2 adders (i.e. exclusive-OR circuits), the number of adders in the second stage being equal to the number of bits in the required code, wherein the adders of the first stage form the parity check bits of the bytes and further bits from selective combinations of bits in the word and wherein the bits outputting the adders of the first stage are distributed, together with further bits of the word, to the inputs of the adders of the second stage. Substantially all the adders of the first stage have at least as many inputs as there are information bytes in the word to be processed and substantially all the outputs of said first stage adders are applied to inputs of at least two adders of the second stage.
Patent ES-439743-A1 (ES)
Title: Mercapto functional polyorganosiloxane release agents for fusers in electrostatic copiers
IPC: C08L83/04
Filed: 1975-07-24
Abstract: Polyorgano siloxanes having functional mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having superior toner release properties for electroscopic thermoplastic resin toners. The polyorgano siloxane fluids having functional mercapto groups interact with the fuser member in such a manner as to form an interfacial barrier at the surface of the fuser member while leaving an unreacted, low surface energy release fluid as an outer layer or film. The interfacial barrier is strongly attached to the fuser member surface and prevents toner material from contacting the outer surface of the fuser member. The material on the surface of the fuser member is of minimal thickness and thereby represents a minimal thermal barrier. The polyorgano siloxanes having mercapto functionality have also been effectively demonstrated as excellent release agents for the reactive types of toners having functional groups thereon.

Title: System for and method of reproducing an image.
IPC: G03G15/32
Filed: 1980-03-21
Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.

Additional layers of the coating may be applied and fired until the oxide coating is about 200 to about 5000A thick, avoiding quarter-wave thicknesses.

Patent ES-8207579-A1 (ES)
Title: Method of using and storing energy from the environment
IPC: F24S90/00
Filed: 1981-06-15
Abstract: The present invention relates to a method of using and storing energy from the environment using a storage medium, especially silica gel or zeolite, which works by means of chemical reactions or sorptions, in which during charging with energy exergy is accumulated to a high density in this storage medium via an inert gaseous carrier medium for the exergy, and during discharging the stored exergy is extracted from the store, as required, also by means of an inert gaseous carrier medium for conversion into heat or cold of the desired level. The method of the present invention is carried out in such a way that: (a) on charging with energy the exergy of smaller imbalances of the environment is accumulated and/or (b) on discharging energy the residual exergy contained in the emerging gaseous inert carrier medium is used for charging a further storage medium, in which no or only a little exergy is accumulated.

Title: Sea-water desalination appts. etc. using solar heat evapn. - has transparent condenser panel continuously cooled by fresh sea-water
IPC: C02F1/14
Filed: 1982-05-24
Abstract: Evapn. of the seawater takes place as it percolates through a layer of sand covering a waterproof sheet on an inclined plane facing the sun. Just above the plane and parallel to it is a hollow panel made of material which is transparent to sunlight but not to infra-red radiation. Fresh seawater is passed upwards through the panel to a header tank above the top end of the inclined plane. Water from the tank is sprayed on the layer of sand where it is evaporated by solar heat. The vapour is condensed on the underside of the panel which is continuously cooled by incoming seawater which, in turn, is preheated on its way to the header tank. Condensate is drained from the panel into a collector. The waterproof sheet is pref. made of high density polythene and the sand layer about 30 cm. thick. The panel material may be methacrylate or the panel may be an inflatable structure. Pref. seawater sprayed on to the sand is precoloured, e.g. with an organic dye or with a dye based on manganese oxide. The installation is for the prodn. of demineralised water from seawater. The temp. differential between the evaporative sand bed and the condensing panel is maintained at a high level by incoming seawater. This offers a high output for the size of installation, e.g. 25 to 30 litres of demineralised water per square metre per 8 hour day.
