Title: Process for manufacturing sintered pellets of nuclear fuel
IPC: G21C3/62
Filed: 1968-02-10
Abstract: Sintered pellets of UO 2 , PuO 2 or ThO 2 or mixtures thereof, for use as nuclear fuel, are made by grinding the oxide(s) into powder, adding to the powder 1 to 7% by weight of a fatty acid salt as a sintering inhibitor, preferably zinc behenate or zinc stearate, cold-pressing the mixture into bodies, breaking the bodies into granules, coating the granules with the sintering inhibitor in a proportion between 0À2 and 1% by weight, cold-pressing the coated granules into pellets, and sintering the pellets in a reducing atmosphere at a temperature equal to or higher than 1500 C. In one example, a finely divided powder of zinc behenate is added to a finely divided UO 2 powder and pellet-shaped bodies of the UO 2 /zinc behenate powder are prepared in an hydraulic press under a pressure of about 1500 bars. The bodies are broken in a mill and only those that pass through a screen of 0À6 mm. but not one of 0À3 mm. are retained. These are coated with between 0À2 and 0À3% by weight of finely-divided zinc behenate in a conventional mixer and shaped by cold-pressing under a pressure between 4000 and 7000 bars to obtain pellets having the desired final shape, except that shrinkage is taken into account. The pellets are sintered for 3 hours in a reducing atmosphere at 1700 C. The density of the pellets is 90% of the theoretical density with 1% zinc behenate added during the first mixing step, 85% with 2À5 to 3% zinc behenate, and 80% with 5% zinc behenate. Such pellets are more suited to retain fission products without the cracks found in higher density pellets when subjected to high burn-up. The manufacture of annular pellets made of a mixed dioxide of enriched uranium and plutonium (U 0 . 8 , PU 0À2 )O 2 for use as fuel elements in a fast reactor is also described.

Patent ES-352577-A1 (ES)
Title: Automatic mobile radiotelephone networks
IPC: H04W84/02
Filed: 1968-04-09
Abstract: In a telephone exchange which can interconnect wired subscribers to radio subscribers over any one of a plurality of radio links and in which an allotter allots from the free radio links one to be used for the next radio call, at least some of the radio subscribers have wired line circuits (through which connections cannot be made but) which store the busy/free states of the subscribers' mobile equipments. The system is generally similar to that disclosed in Specification 1,144,010, the provision of the wired line circuits, however, allows the state of a mobile subscriber's equipment to be tested without engaging one of the radio links. These line circuits are similar to ordinary wired subscriber line circuits and thus special services such as subscriber absent service, routing dead number calls to operators and class of service facilities may be provided for mobile subscribers as for ordinary subscribers. It also facilitates charging. The subscriber's circuit for a mobile subscriber in addition to the usual meter has an additional meter which responds to special metering pulses produced by the exchange during both incoming and outgoing calls of a radio subscriber to incur an additional charge for a radio call. For a call to a radio subscriber the exchange interrogates that subscriber's wired line circuit and if the relays in this circuit indicate that the subscriber is free and available and if this is the case the call then proceeds as in Specification. 1,144,010. For call in either direction the line circuit is updated when the subscriber changes the busy/free state of his radio equipment or indicates that he will be absent from his station. Other radio subscribers (of a more mobile nature) do not have a wired line circuit and calls to them are automatically routed to an operator. Calls to unused numbers are routed to a speaking machine. Reference has been directed by the Comptroller to Specification 1,010,299.
Patent ES-356075-A1 (ES)
Title: Process and apparatus for the manufacture of films and yarns, and the products thus manufactured
IPC: B29C48/20
Filed: 1968-07-12
Abstract: Synthetic films are made by a process in which at least two liquid component polymers are placed side by side in a given order to form a single main stream which is repeatedly flattened and divided to form a multi-layer stream which is forced through an extrusion slit, which in the longitudinal direction thereof extends substantially perpendicular to the planes of the divisions between the layers to form a film in which the layers extend side by side across the film. Advantageously, the layered stream, which has a virtually square cross-section, is transformed at least once while the cross-sectional surface area is maintained constant, into a stream having a rectangular cross-section whose short-side dimension is not smaller than 1 mm. The process is more particularly characterized in that the main stream is made up of at least three components, at least two of which properly adhere to each other in the extruded film but differ widely in shrinkability after drawing in the longitudinal direction of the film and of which at least one other component which hardly adheres to its neighbouring components is present between the components which do not adhere to each other. As the said other component use may be made of a material which is soluble in solvents which do not attack the components that adhere to each other and the film, after it has been drawn or not, is passed through a bath containing these solvents. The said other component may have a melting point which is lower than the softening point of the components which adhere and the film, after it has been drawn or not, is heated. The material for the other component may have an elongation at its breaking point which is lower than that corresponding to the ratio at which the adhering components are drawn, and the film is then drawn. In another embodiment, the main stream is composed of at least 3 components of which in the formed film at least two poorly adhere to each other, and of which at least one other component which properly adheres to its neighbouring components is present between the two poorly adhering components. Threads, fibres or yarns can be made from the film by splitting each film sheet into a large number of threads by a mechanical, chemical or physical treatment. In the examples, the following films are described: (i) a two-component film of nylon 6, and nylon 6 and polystyrene, the polystyrene thereafter being removed, thus forming a fibre sheet, (ii) a two-component film of nylon 6 and polyethylene, the polyethylene thereafter being entirely or partially removed after which the film may be processed into a spun yarn, (iii) a three-component film of nylon 6, polyethylene terephthalate, and copolyesteramide which latter component properly adheres to the first two poorly adhering components, (iv) a three component film of nylon 6, a copolyamide of nylon 6 and 11, and polystyrene, which film can be readily fiberized and split after removal therefrom of polystyrene.

Patent ES-362292-A1 (ES)
Title: Record and random playback mechanism therefor
IPC: G11B33/06
Filed: 1969-01-09
Abstract: In a playback arrangement for insertion in a toy, cam means are provided for randomly selecting which grooved track on tape record 28 is played back. The tape 28 which is endless and coiled in the base of frame 36 is driven by capstan 82 which in turn is driven via a speed reduction mechanism, including friction wheels 74, 76, from electric motor 38. The motor speed is controlled by a weight operated governor which opens and closes a switch in the motor supply to maintain its speed constant. Tone arm 114 is pivoted to the frame and via a cross-bar 122 is in contact with speaker cone 124. The arm carries a stylus which is continuously engaged in one of the record tracks. The record includes a number of sound tracks 14, the ends 14a of which run into a common guide track 18 which runs into the commencement 14b of all the tracks. At the guide track portion the tape is apertured 30 so that the end of each sound track can be detected and the motor stopped. This occurs when a pin 96 on member 92 is engaged by the aperture and moved in the direction of tape movement, against the action of spring 113, until arm 94 attached to the member 92 opens the motor circuit at 100. At the end of this movement a pawl on plate 92 engages in a ratchet wheel 108. When switch 101 is operated to re-energize the device the record advances causing pin 96 to ride up ramp 99 and out of the tape aperture the plate 92 is released and on being returned by spring 113 randomly spins the ratchet-wheel so that as the stylus moves out of the common guide track a cam follower 118 on the pick-up arm engages a new randomly selected position on cam face 112 positioned on the side of the ratchet wheel to select the next track to be played.

Title: Fuel-injection carburetors having fuel regulator
IPC: F02M7/22
Filed: 1969-07-03
Abstract: In a carburetter with a spring-biased injection valve 7 which vibrates when fuel under pulsating pressure is supplied to the injection nozzle 6, the spring-biasing of the valve 7 is adjustable in accordance with the air-flow through the carburetter. In the embodiment shown, the valve 7 is biased against its seat 8 by the spring 19 acting in opposition to the spring 31. The force exerted by the spring 31 is determined by a flap 24 in the carburetter inlet moved angularly about the pivot 25 in accordance with the air-flow through the inlet. The mixture flow is controlled by a sliding throttle valve 4. To increase fuel-flow for starting the flap 24 is manually movable by a member 331 to reduce the mean spring force acting on the valve 7. The fuel is supplied to the nozzle 6 by a pulse generator 33 described in Specification 1, 094, 057. The spring 19 may be located around the vertical arm (22), Fig.2 (not shown), if an L-shaped lever (10), the horizontal arm of the lever having its free end located in an adjustable pivot (371) in the wall of the induction passage. The member actuated by the induction passage air-flow may be an annular plate (38), Figs.3 to 5 (not shown), or a streamlined body (75 or 76) Figs.12 and 13 (not shown), movable axially in the induction passage. The springs producing the mean force closing the valve 7 may be arranged coaxially of the air movable member and one of the springs (48), Fig.4 (not shown), may be a tension spring. The springs may act on the valve 7 through a stirrup-shaped member (34), Figs.10 and 11 (not shown), located for movement by wires (61) or a leaf-spring (60). The member acting on the valve 7 may be guided for axial movement by a plate (56), Fig. 6 (not shown), located by three angularly spaced tension springs (55) or by a pair of axially spaced three-armed leaf-springs (57), Figs.7 and 8 (not shown). The member (34), Fig. 3 (not shown) acting on the valve 7 may be guided in a sleeve (36) fixed in the carburetter body on which the air-flow movable member (38) is mounted. The sleeve (36) may be provided with P.T.F.E. or phenol formaldehyde resin and asbestos fabric bearing bushes (79), Fig.9 (not shown). The air-flow movable member (38111), Fig.5 (not shown) may be movable with increased air-flow in a direction opposite to the flow of air past the nozzle 6 by arranging for the air-flow to reverse direction after passage past the air-flow movable member.
