Patent ES-294647-A1 (ES)
Title: Apparatus for cooling liquids
IPC: F28F25/08
Filed: 1963-12-19
Abstract: Apparatus for contacting gases with liquids for effecting heat transfer or a physical or chemical change therebetween or for removing dust from the gas, comprises a distributor device (5) (Fig. 1) which divides the liquid into streamlets or droplets and subsequently delivers the same by free fall on to dispersion stages (6) while the gas rises in countercurrent relationship between the falling streamlets, the distributor and each dispersion stage consisting of bar-shaped elements 13, the cross-section of which comprises at least one inclined face 15 constituting a receiving plane for the liquid, and a lower step-like portion 17 formed with notches, the bottom of these notches forming inclined or vertical faces 18 having teeth-like extensions, these elements being also provided with portions (e.g. tubular bosses 22 Figs. 3 and 6) constituting means for the spacing of successive elements 13. In use, tubular supports extend through the bosses (22) of a row of the elements 13. In one example (Fig. 1), in which water is cooled by air from a fan (8), the water enters the apparatus from a tank (2) and distributor pass (4) and is finally collected in a vat (7). The fan (8) forces air into the apparatus whilst bladings (9) guide the air to the exit (10). Droplet separators (11, 12) (Figs. 1, and 7-10) are arranged at the air inlet and air outlet of the apparatus in order to prevent water from coming into contact with the fan and from leaving with the air stream. The distributors (5) and dispersing devices (6) each comprise a group of the elements 13. Vertical partitions (20) are placed between successive elements 13 (Fig. 4).

Patent ES-361211-A1 (ES)
Title: Nuclear reactor fuel assembly
IPC: G21C1/00
Filed: 1968-12-07
Abstract: A nuclear fuel element assembly comprises fuel elements arranged in a plurality of groups including an inner group and at least one outer group arranged concentrically around the inner group, the fuel of the elements of a first one of the groups having an initial predetermined enrichment of fissile Pu, and the initial Pu content (if any) of the fuel of the other or at least one other group being markedly different from that of the first. The Pu may be concentrated in the outer fuel elements of the assembly near the regions of highest neutron moderation, i.e. near zones of lowest thermal neutron energy, which arrangement provides for optimization of fuel cycle costs and fuel reliability. Alternatively, the Pu may be concentrated in the inner fuel elements of the assembly, which arrnagement provides for optimization of power and critical heat flux shaping by taking advantage of the increase in the ratio of the thermal fission cross-section of fissile Pu to that of fissile and of the unique higher heat flux capability of the central fuel elements of a boiling water reactor fuel assembly. In the first of these two embodiments, the outer fuel elements contain 1 to 2 atom per cent fissile Pu mixed with depleted or natural U of 0.25 to 0À71 atom per cent fissile U content, while the inner fuel elements contain U fuel of about 3 atom per cent fissile U content. In the second embodiment, the inner fuel elements contain 1 to 2 atom per cent fissile Pu mixed with U of 0À3 to 2 atom per cent fissile U content, while the outer fuel elements contain U fuel of 2 to 3 atom per cent fissile U content.

Title: Device for indicating state of storage of deep-frozen products
IPC: G01N31/22
Filed: 1968-12-21
Abstract: A temperature indicator for frozen foodstuffs which gives an irreversible indication of the temperature of the foodstuff has risen above a predetermined limit during storage comprises a closed thin-walled vessel 1 made of a brittle material e. g. glass or polystyrene, and containing a liquid 2, preferably aqueous, which expands when solidifying to break the vessel 1, a porous material 3, e. g. cotton wool, surrounding the vessel 1 and enclosed in a transparent closed jacket 4, and an indicator 5 e. g. a water soluble dye impregnated on a disc of filter paper, so that if the ambient temperature rises above the freezing point of the liquid 2, the porous material 3 will become coloured due to the interaction of the liquid and the dye of the indicator. The liquid 2 is preferably an aqueous solution of an inorganic or organic material and non-toxic. In particular salts of sodium, potassium, ammonium or calcium may be used preferably as a eutectic mixture which melts at a precisely defined temperature. Inplace of the disc of dye-impregnated filter paper, the dye may be loose in the jacket 4, or alternatively may be dissolved in the liquid in the vessel 1. In some cases the dye itself may function as the substance depressing the freezing point of the liquid, or in cases where a coloured inorganic salt is used the dye may be dispensed with completely. The liquid from the vessel 1 may also be such as to react with a substance added to the porous material 3 leading to a visible change e. g. the liquid may be alkaline and the porous material contain phenolphthalein. Any dry dye present in the jacket 4 may be masked by white blotter paper so as to give a clearer indication of the melting of the contents of the vessel 1.

Abstract: A control is provided for a wire coating line which includes means for driving wire along a path at controllable speed while coating it with plastic extruded at a controlled rate and temperature, and cooling means are located at a controllable distance from the coating means to solidify the plastic. The controllable factors affect both the capacitance and diameter of the wire produced. The control allows the line to be run in accord with stored digital values for the matters to be controlled. Closed loop control is provided because the relevant factors of line operation are measured, the analogue measurements converted to digital values and compared with the stored values to produce a control signal which has the effect of reducing the differences between a desired and measured line condition as represented by the digital values compared. Closed loop control is also provided for control of the line to produce desired capacitance or diameter values in the coated wire. Whichever of capacitance or diameter is used as the basis for line control is measured and provided as a digital value to the control. This digital value is compared to a stored digital value representative of the desired capacitance or diameter. The results of the comparison is used to update the stored digital value for an operating condition of the line so that the parameter is altered to provide an operating condition which brings the capacitance or diameter closer to the desired value.

Patent ES-469109-A1 (ES)
Title: Arrangement for branching an information flow
IPC: G06F9/22
Filed: 1978-04-25
Abstract: Digital words of a pipelined incoming information flow are branched into a number of outgoing information flow branches. The term "pipelined" means that the flow is transferred through memory means whose activation inputs are controlled by clock pulses, the memory means arranged successively with reference to the flow direction being coincidently activated to receive successive words of the flow. A digital branching information flow for ordering into which of the outgoing branches the incoming words have to be branched is generated in step with the incoming flow. The basis for each outgoing branch is obtained from the output of a branching register to which the incoming flow is supplied. The branching registers are activated by the clock pulses, but if an outgoing branch contains only a part of the incoming flow, an activation locking device is used in order to block the clock pulses in dependence on the respective branching information. The branching information flow may be transferred to the locking devices through branching information registers whose activation inputs may also be controlled by locking devices. A branching information register is, however, not to be controlled by the locking device connected to its own output.
