Patent ES-473357-A1 (ES)
Title: Solar concentrator and energy collection system
IPC: F24S23/30
Filed: 1978-09-14
Abstract: A curved prismatic, Fresnel-type lens primarily used for concentrating sunlight in a solar energy collector. The lens comprises a substantially smooth, convex outer surface and a plurality of prisms arranged side-by-side along a curve on the inner surface to direct incoming light to a common area. Each of the individual prisms has a front and back face joined by a bottom face. The front and back faces of the prisms are oriented such that the angle of incidence of the incoming light with the front face is equal to the angle of incidence of the outgoing light with the back face. Further, each of the prisms is arranged along the curve such that they do not obstruct light passing through any adjacent prism. The bottom face of each prism is over-extended beyond the path of the light passing through the prism to prevent loss of light due to blockage by the bottom face or the rounded point between the back face and bottom face. The improved lens is used in combination with a solar energy collector comprising the improved concentrator and a suitable energy receiver for converting incident sunlight into a useful energy output.

Title: Gas-liquid contact process.
IPC: C01B21/40
Filed: 1979-04-03
Abstract: In order to improve the efficiency of nitric acid formation, cold oxygen, typically at a temperature below - 100 DEG C, is introduced into the absorption column in which the nitric acid is formed. With reference to Figure 2 of the drawings, a gas mixture containing nitrogen, oxygen and nitric oxide enters the bottom of absorption column 202 through an inlet 208, and water enters the top of the column 202 through an inlet 206. The column 202 has vertically spaced contact trays 204 down which the water descends, coming into contact with ascending gas mixture and becoming progressively richer in nitric acid. Liquid oxygen is sprayed into the column 202 at oxidation spaces 216 and 218 through vacuum-insulated spray nozzles 255 and 259 respectively. The temperature in the oxidation spaces 206 and 218 is sensed by sensors 277 and 279 respectively. If either of the sensed temperatures falls to a chosen value, relatively warm gaseous oxygen is introduced into the liquid oxygen supplied to the respective spray nozzle. Local freezing of the nitric acid is thus avoided.

Title: In-situ leaching
IPC: C22B60/02
Filed: 1979-10-19
Abstract: The present invention relates to in-situ leaching of uranium, particularly employing an acidic leach liquor containing an oxidant, and especially in respect of ores containing significant amounts of transition metals that act as catalysts for peroxidant decomposition.

The present invention employs peroxymonosulphuric acid as oxidant and thereby ameliorates the problems aforesaid. Preferably, additionally, sulphuric acid is present in the leach liquor and in many preferred embodiments the peroxymonosulphuric acid concentration is from 0.001 to 0.03 moles/liter and the sulphuric acid from 0.025 to 0.075 moles/liter.

Title: Process for the production of a "fuel grade" mixture of methanol and higher alcohols
IPC: C07C27/00
Filed: 1981-05-15
Abstract: A process for the production of a "fuel grade" mixture of methanol and higher alcohols from CO and H2. To reduce the amount of water contained in the mixture coming from the synthesis reactor of the alcohol synthesis the reaction product is cooled and fed to a secondary reactor wherein the reaction of conversion: CO+H2O-><-CO2+H2 is conducted in conditions near to equilibrium. The further reaction product is cooled down further so as to obtain a liquid phase constituted by the alcohols, and in which there are still dissolved some gases, and a gaseous phase containing the carbon dioxide produced in the secondary reactor together with the non-reacted gases. The gaseous phase is sent to a section of absorption of the CO2 wherein the absorbing liquid is constituted by the very alcoholic mixture produced after removal of the CO2 the gas is partly recycled and partly let off in order to avoid the accumulation of inert gases contained in the feeding mixture. Before being used in the section of absorption of the CO2, the alcoholic mixture is sent into a stripping column to remove the gases dissolved therein the let off gases are used as stripping agents. In the secondary reactor of conversion operation is carried out at a temperature comprised between 150 DEG C. and 250 DEG C., at a pressure equal to that of the synthesis reactor and in the presence of a copper catalyst.

Title: Process for firing and cooling of ceramic products, particularly wall and floor tiles, in continuous kiln on a single layer car.
IPC: F27B9/12
Filed: 1981-09-18
Abstract: The process provides that the material is introduced into a furnace with a first prefiring zone, a second firing zone and third cooling zone. Kiln cars move forward in the furnace on which refractory surfaces carrying the load (2) are realized in such a manner as to leave at least one longitudinal interspace (3). In the ceiling of the first zone and in correspondance with the said longitudinal interspace (3) is formed a niche (3 min ) provided with burners (4), the gases coming from which are divided and deflected by means of deflectors (6) from a vertical passage into two horizontal passages in opposite directions. In the second zone, the firing is realized by combustion gases which are fed in horizontally and over the product to be fired, together with the heat supplied from the air originating from the cooling zone, and the distance between the ceiling and the car deck (5 min ) of kiln cars is reduced to a very small amount. Therefore, this results in the greatest reduction possible of the external air volume injected into a tunnel furnace resulting in improvement of the efficiency.

Patent ES-8307597-A1 (ES)
Title: Self restoring pivoting means and print hammer using same.
IPC: B41J9/04
Filed: 1982-02-17
Abstract: A pivoting means for pivoting back and forth a mechanical load such as a print hammer about a given axis and within a low amplitude angle includes two elongated leaf springs. The leaf springs are located in planes at a given angle with respect to each other but both planes being perpendicular to the plane of pivotation of the mechanical load. A frame fixed relative to the pivotable mechanical load is used for attaching the extremities of both elongated leaf springs. The mechanical load is attached to both leaf springs equidistant from their attached extremities. A power source pivots the mechanical load from its rest position to its work or print position causing the two leaf springs to be flexed in torsion. The torsion flexing generates a return torque for self restoring the mechanical load back to its original position.
