Patent ES-337206-A1 (ES)
Title: Preparation of diamine-dicarboxylic acid salts for polycarbonamides
IPC: C07C51/00
Filed: 1967-02-23
Abstract: Aqueous solutions of over 20% concentration of dicarboxylate salts of bis-(4-amino-cyclohexyl) methane of which at least 50% is the trans-trans isomer are obtained by dissolving the diacid and diamine in water in a sealed vessel at 110 to 160 C. and at least autogenous pressure.

Title: Apparatus for the manufacture of artificial chamois leathers without textile supports,especially of regenerated cellulose
IPC: B29D7/01
Filed: 1967-04-12
Abstract: Cellulose regenerated sponge cloth is made by extruding, on to a moving conveyer belt 5, viscose paste containing reinforcing fibres in string or ribbon-like form to produce a deposit of a series of juxtaposed parallel strings or ribbons, in which the fibres are oriented along the lengths thereof, extending at right-angles to the direction of travel of the belt and, prior to conduction through a regeneration and finishing bath, spreading the paste into a film of predetermined thickness, in which the fibres are disorientated and the strings blended, by means of a ribbed roller 8 extending at right-angles to the direction of movement of the belt and which rotates at a surface velocity equal to that of the belt 5. The extrusion head 1 is provided with a plurality of nozzles 2 and reciprocates on rods, and between stops 4 at either end thereof, across the diameter of a turntable 3 which alternately rotates through a predetermined angle in different directions at either end of a traverse of the head 1 whereby, in conjunction with the velocity of the belt 5 and of traverse of the head 1, each deposition of strings is parallel to that preceding and at right angles to the direction of travel of the belt. The strings are parted from the extrusion nozzles 2 at the end of each traverse by a plate 6. The movements of the turntable 3, extrusion head 1 and plate 6 are controlled by fluid pressure operable rams 10, 11 and 7, respectively. The viscose paste is fed to the head 1 by a pump. A photo-electric cell 9, or a contact roller, monitors the build-up of paste in front of the roller 8 whereby the rate of deposition of the strings, e.g. the pump delivery or the timing of the extrusion cycle, is varied to maintain an even build up. The head 1 may comprise variable die orifices whereby the build-up at roller 8 is controlled. The belt 5 may be provided with surface designs to be reproduced on the film.

Title: Nuclear reactor fuel charge-discharge installation
IPC: G21C19/10
Filed: 1968-04-11
Abstract: A heavy water moderated gas-cooled reactor core 12 is refuelled through channels 13 extending through a slab 19 into a space 18 provided in the pressure vessel 10. The refuelling is performed by a handling facility A described in Specification 1,219,795 which may place a number of spent fuel elements end-to-end in a thimble (Fig. 4, not shown) secured by a lock to the upper end of a pit 20. There are a number of pits 20 but only one is shown, and in alignment with each pit is a passage 30 extending through the roof of the pressure vessel to a metal dome 32 enclosing a winch (Fig. 2, not shown). An extension 48 of the pit leads to a lock 54 controlled by valves 60, 61, the thimble being unlocked and then lowered by a grab controlled by the winch into the lock where it is again locked. Whilst the thimble is in the pit 20, extension 48 and lock 54 it is cooled by the reactor coolant gas. For emergency use, the lock is surrounded by a box 58 through which water may be circulated. The thimble, after unlocking and opening of valve 61 is lowered by a tappet 78 into a magazine tube 72, the magazine then being rotated so that tube 72 lies beneath guide tube 71. A grab operated by a winch 82 lifts the fuel elements one-by-one from the thimble and places each element in a tube 84 leading to a storage pool 86. New fuel elements on a carriage 88 are introduced by lowering them by a gantry 90 through a tube 92 into a magazine tube.
