Patent ES-375022-A1 (ES)
Title: Improvements in or relating to the production of laminar articles
IPC: B29C44/04
Filed: 1969-12-30
Abstract: In a process for making a laminate having a core and surface skin of dissimilar synthetic resin compositions, wherein a charge of the skin composition is injected into a mould cavity and subsequently a charge of the core composition is injected into the interior of the charge of the skin composition before the latter has set, the mould cavity is filled with the skin composition and then enlarged to allow the core composition to be injected. This enlarging of the mould may be effected by reducing the mould clamping force so that the injection pressure forces the mould halves apart. Alternatively the cavity may be fully enlarged before any of the core composition is injected. If the core composition is a foamable material the cavity is then further enlarged to allow foaming to take place. Three charges of material may be injected the third being of the same material as the first. One or more walls of the mould may be lined with a removable insert e.g. a sheet of wood, hardboard, metal or plastics or a flexible material to be incorporated in the moulded article. Articles specified are furniture, building panels and panels for cars and trains, interior trim for vehicles and seedboxes. Examples are given of suitable thermoplastic and thermosetting plastics and foaming agents. Reference has been directed by the Comptroller to Specification 1,156,217.

Patent ES-430489-A1 (ES)
Title: Synchronizing circuit including two flip-flops and circuit means to protect a synchronized signal from an unstable state of the flip-flops
IPC: H03L7/04
Filed: 1974-09-28
Abstract: The disclosed synchronizing circuit employs flip-flops to synchronize a data signal to a clock pulse. The two flip-flops are controlled by the clock pulse and a delayed data signal to at least one of the flip-flops, the other flip-flop also being controlled by a delayed data signal or the data signal directly. A temporizing circuit receives the clock pulse and the output signal of one flip-flop and delivers a signal having a variable time delay according to the phase conditions between the data signal and the clock pulse. An AND gate or an appropriately connected JK flip-flop receives the output signal of the other flip-flop and the output signal of the temporizing circuit to provide the desired synchronized output pulse. This synchronizing circuit protects against the flip-flops synchronizing in an unstable state due to the critical period of the sampling edge of the clock pulse.

Patent ES-443305-A1 (ES)
Title: Method and apparatus for the production of foundry molds
IPC: B22C15/30
Filed: 1975-12-09
Abstract: In the production of a foundry mold utilizing mold forming apparatus which includes a pattern device, a molding box arranged on the pattern device and a frame attached to the molding box, a surplus amount of molding sand is initially filled in over the pattern device in excess of the amount required for the production of the mold and during the production operation the excess sand is stripped off by profiled stripping means which are moved relative to the molding box to strip the excess sand along a profile which is dependent upon the configuration of the pattern device. In one aspect of the invention a single profiled stripper may be used and in another aspect a plurality of strippers having differring profiles may be employed. In other aspects of the invention different mechanisms are applied to move the stripping means relative to the molding sand by movement of the pattern device either along a linear path or through a circular path. The stripping means may be formed as stripper plates having an arcuate configuration or they may comprise flat planar profiled strippers. In a further aspect of the invention, the pattern device together with the molding box is rotatably movable from a filling position to a compression position while the stripping means are simultaneously rotated in the same angular direction as the molding box but in such a manner as to effect opposed linear movement between the molding box and the stripping means thereby to effect performance of the stripping operation. The method of the invention requires only a single compression operation which may involve either compression of the molding sand or simultaneous compression and jarring.
Patent ES-447866-A1 (ES)
Title: Process for the preparation of uranium dioxide
IPC: C01G43/025
Filed: 1976-05-13
Abstract: An actinide dioxide, e.g., uranium dioxide, plutonium dioxide, neptunium dioxide, etc., is prepared by reacting the actinide nitrate hexahydrate with sodium dithionite as a first step the reaction product from this first step is a novel composition of matter comprising the actinide sulfite tetrahydrate. The reaction product resulting from this first step is then converted to the actinide dioxide by heating it in the absence of an oxygen-containing atmosphere (e.g., nitrogen) to a temperature of about 500 DEG to about 950 DEG C. for about 15 to about 135 minutes. If the reaction product resulting from the first step is, prior to carrying out the second heating step, exposed to an oxygen-containing atmosphere such as air, the resultant product is a novel composition of matter comprising the actinide oxysulfite tetrahydrate which can also be readily converted to the actinide dioxide by heating it in the absence of an oxygen-containing atmosphere (e.g., nitrogen) at a temperature of about 400 DEG to about 900 DEG C. for about 30 to about 150 minutes. Further, the actinide oxysulfite tetrahydrate can be partially dehydrated at reduced pressures (and in the presence of a suitable dehydrating agent such as phosphorus pentoxide). The partially dehydrated product may be readily converted to the dioxide form by heating it in the absence of an oxygen-containing atmosphere (e.g., nitrogen) at a temperature of about 500 DEG to about 900 DEG C. for about 30 to about 150 minutes.

Title: Apparatus for conveying bottles
IPC: B08B9/44
Filed: 1976-11-04
Abstract: In moving bottles to and from a cleaning machine, the bottles are transported over a stationary support surface by drivers formed on a plurality of juxtaposed rotating discs. Each disc has a pair of angularly spaced drivers and rotates about a common axle. During rotation of the disc, the axle moves transverse to its axial direction back and forth along a substantially straight path. For each complete back and forth movement of the axle, the disc rotates through one-half of a revolution so that one driver of each pair transports one or more bottles from a first station to a second station while the other driver of each pair returns from the second station to the first station.
