Patent ES-462608-A1 (ES)
Title: Photochemical diodes
IPC: H01M14/00
Filed: 1977-09-24
Abstract: Photochemical diodes are provided which use light to drive both endoergic and exoergic chemical reactions such that optical energy is converted into chemical energy. The photochemical diodes are typically suspended in a bulk volume matrix of the constituent chemical reactants. The photochemical diodes, in the form of either Schottky-type diodes or p-n type diodes, are employed, for example, to convert water into hydrogen plus oxygen (or hydrogen peroxide) to convert hydrogen sulfide into hydrogen plus sulfur and to photo-catalyze chemical reactions. The photochemical diodes of the invention comprise two portions, a first portion comprising an appropriately doped semiconductor material of a given conductivity and provided with an ohmic contact and a second portion comprising either metal (Schottky-type) or an appropriately doped semiconductor material of a conductivity type opposite to that of the first portion and provided with an ohmic contact (p-n type). The two portions are intimately joined together through the ohmic contact(s). Solar radiation is conveniently employed as a source of optical energy.

Title: Glossy fibres of the modacrylic type having reduced inflammability, and compositions of matter and process for producing the same
IPC: D01F6/40
Filed: 1977-11-02
Abstract: Modacrylic fibres from acrylonitrile, vinylidene chloride, and a sulphonated comonomer, having reduced inflammability and high glossiness and dye yield are prepared by wet spinnning a polybend obtained by mixing two binary copolymers, the first from acrylonitrile and the sulphonated comonomer, and the second from acrylonitrile and vinylidene chloride. As the sulphonated comonomer, a significantly homopolymerizable monomer is used, viz. a monomer which homopolymerizes with a conversion of at least 30-40% by weight, in the presence of azobisisobutyronitrile catalyst, under given standard reaction conditions. Preferred sulphonated monomers are acid or salts of the acrylamidoalkanesulphonic series. The spinning dope is a polyblend solution in an organic solvent chosen among dimethylformamide, dimethylacetamide, and dimethylsulphoxide, mixed with water.

Patent ES-8203117-A1 (ES)
Title: Arrangement with a bobbin support.
IPC: D01H1/18
Filed: 1980-09-26
Abstract: The present invention concerns the production of fancy yarns, in which during open-end spinning a roving is supplied program-controlled to the spinning unit for the yarn to be produced. According to the invention at least one roving bobbin is supported by a support member, which is detachably arranged on a can used as a receptable for the fibre material to be processed. The bobbin creel used up to the present for the bobbins impairs the accessability of the winding locations for the fancy yarn produced. This creel, according to the invention, no longer is required. Thus, the cumbersome mounting and dismantling of the creel in changing over from normal yarn to fancy yarn and vice-versa is dispensed with. According to the invention the alterations required for such changes of the yarn production mode are extremely simple.

Title: Venetian blind.
IPC: E06B9/322
Filed: 1981-01-23
Abstract: A venetian blind comprises a windup drum for a lifting strap firmly fitted to a drive shaft. Lateral hub portions of a drum are provided with teeth which serve as contact surfaces for two setting straps. Supporting twines for tiltable slats are suspended from the setting straps whose both ends are connected to the associated one of the other strap by connecting plates which act as stop members. Bearing brackets of the drive shaft, accommodated in a supporting housing of the blind, are provided at their bottom with guide webs, for the setting straps and the lifting strap. Stop lugs provided on a bearing bracket in the housing, cooperate on one side with the connecting plate and on the other side with an engaging member of setting strap. During lifting of the blind, the lugs limit the open position of the straps, and during lowering of the blind, they set the predetermined oblique position of the slats. Pawls, which are radially displaceable in the windup drum, cooperate with the engaging member to close the slats if lifting strap is in its wound-off position. To secure the slats against wind action, i.e. in their open position against closing, or in a predetermined position against further opening, lock cams cooperating with teeth portions of the drum are provided on setting straps.

Patent ES-8206233-A1 (ES)
Title: Method of dividing stock materials.
IPC: B21B15/00
Filed: 1981-03-18
Abstract: The method for dividing stock materials into part lengths, in a production process extending over at least two processing stages, especially in rolling or continuous casting plants, can be performed either with a view to maximum piece weight of the parts or to division without leftover ends. As a criterion for the decision as to which dividing method should be employed, the change in productivity which results in at least one part-length processing stage downstream of a first stage when dividing with a view to maximum piece weight and when dividing with a view to freedom from leftover ends, taking into account the minimum time intervals to be maintained between successive part lengths, is determined and a comparison made with the change in the yield from the processing stage in which the stock materials are divided when dividing with a view to maximum piece weight and when dividing with a view to parts free from leftover ends. If the result of the change in the productivity in the downstream processing stage(s) is larger than the result of the change in the yield from the upstream processing stage, division is carried out with a view to maximum piece weight and if the result of the change in the yield from the upstream processing stage is larger than the result of the productivity change in the downstream processing stage(s), division is carried out with a view to freedom from leftover ends.
