Title: Nuclear reactor with integrated heat exchangers
IPC: G21C1/00
Filed: 1968-02-24
Abstract: An integral nuclear reactor has at least one off-centre extraction opening at one end of its prestressed concrete pressure vessel for the insertion or withdrawal of any one heat exchanger unit, a support for these units being coaxial with the vessel and rotatable about the axis of the vessel so as to bring any one unit into a position opposite to an extraction opening for withdrawal of the unit from the pressure vessel and for substituting another unit in the vacated operating position on the support. In the embodiment shown in Fig. 4, all the heat exchanger units 10 are connected to a single central manifold 44 which is of annular shape and disposed around a passageway 4 provided for a fuel element handling device 5. The manifold 44 extends outwardly through the pressure vessel wall in a series of conduits 46 which are connected to the heat-removal circuit by means of flanges 48. The number of conduits 46 is distinctly smaller than the number of heat exchanger units 10. The assembly of manifold 44 and conduits 46 is fixed inside a tube 50 which is rotatably mounted in the top wall of the pressure vessel. Outside the pressure vessel, the tube 50 is fixed to an annular member 56 supported by jacks 58 either on a stationary annular member 60 or on a ballbearing 62. The annular member 56 is provided with an externally toothed wheel 64 which is rotated by a suitable drive mechanism. By this means, the manifold 44 and the heat exchanger units 10 are rotated. Balls 74 in a channel formed partly in the pressure vessel wall and partly in the tube 50 support the rotary assembly when the annular members 56, 60 are disassembled for the purpose of renewal of the seals 61 placed within the annular member 60. Flanges 70 serve to connect each heat-exchanger unit 10 to the conduit 72 through which hot secondary fluid is discharged to the manifold 44. A biological shield plate 76 which is fixed to the manifold 44 and extends to the heat-exchanger units 10 serves to protect the operator against any residual radioactivity emanating from the reactor core during the replacement of a unit 10. By rotating the tube 50, any damaged heatexchanger unit 10 can be brought into position beneath an opening 2 in the pressure vessel, whereupon it is disconnected from the manifold 44 and replaced.

At say feed 15, all needles with butts at levels 19 and 20 will be raised to clearing height by cams 26, with butts at level 23 confined by the rear face 24c of main stitch cam 24, all needles with butts at level 22 will be raised to tuck height by tuck cams 27 with butts' at level 23 also confined by cam face 24c and, at tuck height, butts at level 22 guarded by cam 29 and all needles with butts at level 21 will pass through the feed with any overthrown needle being lowered by guard cam 30. All raised needles will then be partially lowered by the fixed main stitch cam 24 acting on butts at level 23 with butts at level 19, 20 or 22 guarded by the rear faces 26b or 27b of cams 26 or 27. Adjustable auxiliary stitch cams 25 then act on all butts at level 18 to fully lower needles to knit height with butts at levels 19, 20 or 22 still guarded by the rear faces of cams 26 or 27. To prevent overthrow all butts at level 18 are guarded by cams 28 which are movable with auxiliary stitch cams 25. A second embodiment with a pattern wheel is described in which the pattern wheel acts on butts at one level and the main and auxiliary stitch cams again act on butts at their own levels.

Patent ES-393250-A1 (ES)
Title: Dissolving a volatile fraction in a liquefied gas
IPC: B01J4/00
Filed: 1971-07-14
Abstract: A volatile gas such as nitrogen is dissolved in a liquefied gas such as natural gas, by providing a relatively small interface between the vapor and the liquid at a low flow rate of the vapor toward the liquid, and a relatively large interface at a relatively high flow rate of the vapor. This is done by introducing the vapor and the liquid into an upright conduit in which is disposed a spherical container for the liquid. The spherical container has a perforated bottom. A low vapor flow rate, the liquid immerses the container and the interface is small but at a high vapor flow rate, the liquid level in the conduit is forced down below the perforations of the container, and these exposed perforations establish jets of liquid through the vapor, thereby increasing the interface.

Patent ES-431122-A1 (ES)
Title: Radio telephone system
IPC: H04B1/50
Filed: 1974-10-17
Abstract: A portable duplex radio telephone system includes at least one base station transmitter having a predetermined base transmission range, and a plurality of portable or mobile units each having a predetermined portable maximum transmission range predeterminately shorter than the base transmission range. Satellite receivers are deployed about the base station within the base station transmission range for receiving transmissions from the portable units. The base station transmitter transmits signals on a signalling channel and on at least one communications channel. Each transmitter signalling and communications channel has a frequency that is paired or associated with a receiving frequency of the satellite receivers. In a multiple base station system, the portable receiver has means for scanning the base station transmitter signalling frequencies and for tuning the portable transmitter to the signalling frequency associated with the frequency of the strongest signalling signal received from the base transmitter. When communication is initiated, the portable transmitter and receiver are automatically retuned to one of the communications channels as determined by the strongest signalling frequency received by the portable receiver and by channel availability. Means are also provided in the system to continuously locate a portable unit and switch the operating frequency thereof as the portable unit moves between base station transmitter coverage areas. Further means are provided to automatically reduce the output power of each portable transmitter to the minimum level required for satisfactory communications in order to reduce battery drain and the interference caused by the portable transmitters.

The receptacle preferably is in the form of one molded piece and, as sold, the cover is sealed in place with a lyophilized reagent in at least one of the chambers. Preferably the aforesaid passage is of such restricted cross-section as to prevent gravitational flow of aqueous liquid from one of said chambers to the other when the level of liquid in said chamber is substantially above the uppermost portion of said passage and is substantially above the level of any liquid in the other chamber while being large enough to permit, responsive to applied pressure, the forcing of aqueous liquid through said passage so as to be injected into the other chamber and thereby become commingled with liquid in the other chamber.
