Patent ES-441440-A1 (ES)
Title: In situ carbonate leaching and recovery of uranium from ore deposits
IPC: E21B43/28
Filed: 1975-10-02
Abstract: Uranium ore deposits which contain certain proportions of other metals and elemental components, such as are present in redox roll front ore deposits, are selectively leached in situ by passing therethrough relatively dilute aqueous leach solutions comprising essentially from about 0.5 to 5 grams per liter of ammonium bicarbonate and from about 0.1 to 3 grams per liter of peroxide, preferably introduced as aqueous H2O2, and sufficient ammonia to bring the solution to a pH of from about 7.4 to 9, and preferably from 7.5 to 8.5, thereafter withdrawing from the ore deposit the aqueous leach solution enriched in uranium which it preferentially extracts along with a generally lower proportion of other metals and elements as compared to their respective ratios in the ore deposit, and contacting the enriched leach solution with a strong base anion exchange material to strip the uranium from the leach solution. The uranium is eluted by treating the base anion exchange material with an aqueous eluant, and finally the uranium is recovered from the uraniferous eluate by first acidifying it and then treating with ammonia to produce a precipitate of relatively pure ammonium diuranate. The stripped leach solution is separated from the base anion exchange material and the stripped leach solution is recirculated through the ore deposit after adjusting it with more ammonium bicarbonate, peroxide and ammonia. After the uranium in the ore deposit is removed to the extent economically practicable, the leach solution is replaced with an aqueous reducing solution which is passed into the ore deposit in order to precipitate and render insoluble any uranium and elements such as vanadium, molybdenum and selenium. The process produces above ground a very low volume of impurities and waste solutions requiring disposal, and causes no significant or material contamination or deterioration of the underground deposits or any aquifer associated therewith.

Patent ES-463681-A1 (ES)
Title: Compressive treatment of web materials
IPC: D06C21/00
Filed: 1977-10-28
Abstract: Improved machine and method for longitudinal compressive treatment of webs employing a two roll drive nip. Specially arranged initial parts of one or a pair of stationary retarding members are positioned at the exit side of the drive nip in the region of minor divergence of the roll surfaces to provide damming forces. The initial part of the retarding member, preferably a curved, resilient nipping element, is shaped to oppose the flow of the web. By its construction and position close to the line of centers of the rolls, it establishes a very compacted column extending upstream to an initial treatment point continually located in the drive nip, between the moving surfaces of the rolls. In this region, longitudinal compressive action occurs upon the web in a continuous and uniform manner, preferably with compensatory action in response to variations in the forces exerted by the compacted column of web. This compensatory action is provided by resilient deformation of a retarding member in the direction normal to the plane of the web, resilient adjustment movement of a retarding member in the direction away from the nip roll center line, and in some cases, by resilient response of the compacted material itself. The retarding members may accomplish their resilient movement by swinging about the roll axes and by moving longitudinally of the web flow path. The retarding member, or the leading member of a pair, preferably, in the start-up position, has its initial part located upstream of the running position.

Title: Arrangement for measuring the ratio between a number of events occurring after each other in a first and second series of events.
IPC: H04M3/22
Filed: 1979-02-02
Abstract: Arrangement for measuring the ratio between a number of sequential events occurring in a first series of events and a number of events in a second series of events, each series activating a pulse generator (P1, P2) included in the arrangement. The arrangement further comprises a counter (C) which is stepped forward by the pulses generated by the pulse generator (P1) controlled by the first series of events. A multiplying arrangement (D1) receives the counter value of the counter (C) and multiplies this value by a factor m where m indicates a selected part of the received counter content. The multiplying arrangement (D1) receives on a control input, a pulse from the pulse generator (P2) controlled by the second series of events. When the arrangement (D1) receives that pulse it feeds a signal to a subtracting input of the counter (C), which signal reduces the counter content by a number of steps corresponding to the multiplication result, so that the counter content varies between two limit values. An indicating unit (I) is arranged for indicating the difference between this two limits thus showing the quotient between the number of events of the two series of events.

Title: Power Steering Valve and Method of Making the Same
IPC: B62D5/22
Filed: 1980-02-12
Abstract: An improved power steering valve has a cylindrical sleeve which circumscribes an inner valve member. The valve sleeve has relatively short inner grooves 100, 102, 104 and 106, which extend in opposite directions from a central portion of the sleeve. Although the inner grooves can be sequenfially formed with an end mill, a pair of axially extending inner grooves are advantageously formed at the same time by simultaneously cutting away material from the inside of the valve sleeve with a pair of rotating end mills. When a pair of axially extending inner valve grooves are being formed by the use of two end mills, the end mills extend into the valve sleeve from opposite axial ends of the valve sleeve.
