Patent ES-453114-A1 (ES)
Title: Method and apparatus for recovering by-product silt fines from a slurry thereof
IPC: B01D21/00
Filed: 1976-11-08
Abstract: The present invention relates to a method and apparatus of recovering by-product fines, such as coal fines, by-product fines created in the manufacture and processing of metals or any very finely divided substance which may be of value when recovered to a usable form and which may be naturally found in the form of a silt or as the result of the manufacturing process, from a slurry or sludge thereof. The slurry mass is first treated to dissociate it into discreet units, if required, for further treatment to recover the fines contained within the discreet units of the slurry in the form of a usable end product. The discreet units of the dissociated slurry are conveyed through a rotary-driven impeller feed conveyor and simultaneously a hot gas such as air or superheated steam is flowed through the conveyor in contact with the slurry segments or discreet units. This combined action of the rotary impeller feed and the flow of hot air uniformly breaks up and dries the discreet slurry units into particles of desired moisture content. If additional drying is required, the present invention teaches the use of a second rotary-driven impeller feed conveyor in which the extruded agglomerates are conveyed while again simultaneously flowing a hot gas through this second conveyor in contact with the agglomerate to break up or size and further dry the agglomerates to a desired degree.

Title: Rupture resistant adhesive tape - contg. fusible adhesive reacted with crosslinking or copolymerising cpd.
IPC: C09J7/20
Filed: 1977-10-21
Abstract: Adhesive tapes are made by coating with adhesives, pref. fusible, which are based on copolymerised and/or transversally crosslinked polymers. These are made by heating >=1 polymers to 130-160 degrees C, homogenising pref. by mixing, and then adding the co-reacting or crosslinking material. This effects copolymerisation, or pref. transversal crosslinking, and the reaction prod. is applied to the support. Pref. co-reacting or crosslinking material is added in the molten state or as a soln. or dispersion in an organic solvent, pref. in a mineral oil, during or after the homogenisation stage. Alternatively, it can be applied first of all on the front or back of the support, followed by the polymers copolymerisation and crosslinking taking place directly on the support. The polymer used is pref. butadiene-styrene, isoprene, natural rubber, butylchlorinated rubber, or an ethylene-propylene polymer. The method allows the application of adhesives without requiring a solvent, elevated temps., or large quantities of plasticisers to maintain the viscosity low enough for application. The present invention allows fusible adhesive to be used on industrial or packaging tapes, by increasing the rupture resistance under load through the change from thermoplastic to thermosetting properties.

Patent ES-8303073-A1 (ES)
Title: Vein distention apparatus.
IPC: A61B17/00
Filed: 1982-01-14
Abstract: Apparatus 10 for the distention and irrigation of a saphenous vein which is being tested prior to use as a coronary or peripheral bypass graft includes a specially-configured cannula 70 for insertion into the vein 90, and a pressure-limiting device 40 having a resilient membrane reservoir 54 which limits the hydrostatic pressure delivered to the vein to a predetermined level. The device is connected between the cannula inserted into the vein and a syringe 20 filled with irrigation fluid. As fluid is delivered under pressure from the syringe 20, the membrane reservoir 54 fills with fluid and inflates within a specified range of pressures so that, if excessive force is applied to the syringe, the membrane inflates and the pressure transmitted to the vein cannot exceed a predetermined maximum pressure. A stopcock 36 connected between the syringe and the membrane allows the membrane to be pressurized with the contents of the syringe. With the membrane filled and pressurized, the stopcock is closed, allowing the membrane to act as a reservoir which irrigates the vein at a constant, controlled pressure without further use of the syringe. The cannula has a tapered and bevelled tip which allows easy insertion into the vein, and a sloping shoulder just proximal to the tip which provides a convenient site for firmly securing the vein to the cannula with a ligature.
