Title: Gas cooled nuclear reactor power plant
IPC: G21C15/02
Filed: 1964-07-31
Abstract: A nuclear reactor and a heat exchanger separated from each other by radiation shielding are disposed in a vessel which is mounted within a second vessel a first annular zone is defined by the adjacent walls of the two vessels, and the wall of the inner vessel is a double wall having between the two walls a further annular zone a secondary coolant is circulated through the first annular zone at a temperature below the temperature of the primary coolant leaving the heat exchanger. The reactor 2 is supported on a radiation shield 28 mounted at its periphery on the inner wall 22 of the double-walled inner vessel. The heat exchanger 4 is mounted indirectly on a bed-plate 20, which also supports the double-walled container. The second or outer vessel 6 is of concrete, and acts as a restraining vessel for the primary coolant pressure. The object of the invention is to protect this vessel from the hot primary coolant, and this is achieved by passing cool CO 2 gas through the regions A, B and C at a slightly higher pressure than the primary coolant pressure. Three embodiments are described. In the first, as shown, secondary coolant passes from pump 72 through lines 74, 76 to zones B and 10. Gas from B flows up through annular zone F and out through pipe 78. Gas from fuel handling zone 10 filters down to zone C through leakage ducts in the fuel channel cap 38, and radially out through zone C to the exit. A portion of reactor primary coolant (also CO 2 ) is bled off through line 84, cleaned, and fed into the secondary coolant circuit there will be slight compensatory leakage of secondary coolant into the primary circuit. In the second embodiment, a single series secondary circuit is used: 72, 74, B, A, 10, standpipes, C, 78, 80, 72. In the third embodiment, no reversal of flow takes place in the shield 12 the flow is: 72, 74, B, A, C, standpipes, 10, and, via an outlet pipe in 10, to the pump 72. In the fourth embodiment, all the secondary gas passes through the standpipes into the primary coolant, instead of directly to the pump 72. The pipework and circulation are as in Fig. 1, except that circuits 76, 78 are removed.
Patent ES-336112-A1 (ES)
Title: Mechanical treatment of materials for longitudinally compressing the same
IPC: B31F1/12
Filed: 1967-01-26
Abstract: An advancing length of textile material of predetermined thickness is mechanically compacted by driving the material through a passage defined by an overlying material-contacting cover member and an underlying driving means, the material being caused to travel through the passage at a first substantially continuous speed with no substantial change in thickness, and abruptly increasing the thickness of the material by applying a retardant force to decrease the speed of advance thereof, the retardant force being applied to the material by an overlying extension of the cover member having an higher coefficient of friction than that of the material-contacting portion of the cover member in the passage so that the material is forced to accumulation and longitudinally compress in an accumulation cavity immediately adjacent the passage. In one embodiment, Figs. 2 and 4, sheet material 8 which may have been pre-stretched or impregnated with a cured or non-cured resin, passes from a supply onto the surface of a driven roll 7 which may be heated internally. The surface of the roll 7 may be roughened, e.g. formed with knurls 13. The cover member comprises a member 9 which comprises a shoe 14 mounted on a block 16 by arms 15 pivoted at 17. Air cylinders 18, mounted on the block 16 and each provided with an adjustment device 20 to alter the force applied thereby actuate the shoe 14. A flexible steel plate 21 is mounted on the shoe 14 by a holder 22 and extends over the roll 7 to form a first passage therewith. Pressure is applied to the free end portion of the plate 21 by plates 23, 24, preferably steel, removably mounted on the shoe 14 by a clamp 25. A strip 27 of silicone rubber secured under a steel plate 28 is mounted between the plates 23, 24 and the plate 21 to form the accumulations cavity with the roll 7. After compact- 'ing, the material is taken-up by a roll which is driven at a speed less than that of the roll 7 to take-up the material in its compressed state while maintaining the degree of longitudinal compression therein. Subsequently, the material may be permanently set, e.g. by heat setting on a tenter frame. In a modification, Fig. 5, a lip loader 30 applies additional pressure to the plate 28 along the line Q of minimum passage of the material 8 and comprises a plate 31 mounted on the clamp 25 by a bracket 32. A screw 35 applies pressure to the plate 31 which extends across the width of the material. In a further modification, Fig. 6, an auxiliary pressure applying means may be directed against the free edge of the strip 27 so that a second cavity is formed between lines Q and R.

Patent ES-358715-A1 (ES)
Title: Method of making multiple cold crimp sleeve plug and socket
IPC: H01R4/20
Filed: 1968-10-02
Abstract: A method of forming a multi-contact electrical connector involves inserting socket contacts 4 which have been crimped to the conductors of wires 5, in insulating sleeves 1 which are joined by a web 2. Each sleeve is then cold-crimped at 7 about a contact to retain the contact in the sleeve. Usually all the sleeves are crimped in one operation. A portion of the web 2 may be removed before crimping, allowing complete peripheral crimping of the sleeve. A two-part coupling according to the invention comprises two such connectors having sleeves and contacts of different diameters but having sleeves spaced the same distance apart allowing one connector to be inserted into the other. Connectors may be made from an insulating strip of indefinite length, portions of sleeves 1 being removed at intervals to define individual units into which contact-terminated wires are successively crimped, each unit being severed from the length at the time of crimping.
