Patent ES-331993-A1 (ES)
Title: Nuclear reactor
IPC: G21C19/04
Filed: 1966-10-06
Abstract: A nuclear reactor is cooled by a coolant flow in channels of constant cross-section which are each occupied by a train of fuel cartridges, each cartridge being formed by a fuel element supported in a tubular jacket of moderator material, the jacket of at least the terminal cartridge at the channel end opposite that through which the cartridges are unloaded being of smaller cross-sectional area than the jackets of the cartridges in the channel nearest the end through which the cartridges are unloaded. By this means the force due to the coolant flow acting on the terminal cartridge when this is the last remaining during discharge of the cartridges is limited to an appropriate value. In the preferred embodiment, as shown in Fig. 3, a channel 4a of constant cross-section contains a stack of fuel cartridges all of similar construction, the terminal cartridge 17, for example, being formed by a graphite jacket 18a containing a fuel element 20a borne by a saddle 22a connected to the jacket by retaining wires 23a and centred by partitions 24a. The o.d. of the jacket 18a (like that of the jackets further up the channel) is such that only a slight gap exists between it and the channel wall and substantially all the cooling gas, e.g. CO 2 , flows between the jacket 18a and the fuel element 20a. At least the bottom cartridge 17 has a jacket 18a whose i.d. is greater than the i.d. of the jackets 18a11, 18a111 of the standard cartridges 1711, 17111 in the top part of the channel. The force experienced by the cartridges, more particularly by the fuel elements, is therefore less for the bottom cartridges 17 than for the standard cartridges. In an alternative embodiment, all the jackets have the same i.d., the upper jackets being in close contact with the channel wall whereas the lower jackets are spaced from the channel wall. During normal operation, therefore, substantially all the coolant flows between the jackets and the fuel elements but once the upper cartridges have been removed, a by-pass flow occurs between the lower jackets and the channel wall. The total flow through the channel increases but the pressure drop between the ends of the remaining cartridges, and the force experienced thereby, decreases because of the increased pressure losses due to the fixed elements of the channel, more particularly the debris collector at the bottom of the channel.

Title: Drive mechanism for actuating a windscreen washer pump from a windscreen wiper motor
IPC: B60S1/48
Filed: 1967-02-28
Abstract: A drive mechanism for actuating a windscreen washer pump from a windscreen wiper motor comprises a cam member 30 rotated by the wiper motor shaft 9 and having cam pins 31 engageable with a star wheel 40 forming a Geneva movement the star wheel having a gap at one portion so that the cam member 30 may rotate without rotating the star wheel 40. The star wheel has unequiangularly spaced recesses 47 having sloping sides in which are engageable projections 54 on a cam wheel 50 which has a plurality of cams 51 which are engageable with a cam follower lever 60 pivoted at 14 and attached to the pumping member 21. The cam wheel 50 is held against the star wheel by a spring 15 but on overload may part the cams 51 may be shaped to cause parting on overload. A rocker 80 is also pivoted at 14 and is biased against a polepiece 73 of a solenoid by a spring 83. When the polepiece 73 is raised the rocker pivots so that the end of an arm 81 engages a shoulder 46 on the star wheel and a portion 82 comes into the track of cams 32 on the cam member 30 so that the star wheel is given angular movement to cause the Geneva mechanism to operate and the cam wheel to rotate. During rotation the rocker is restored to inoperative position by a shoulder (49) on the star wheel engaging an arm 86. Operation of the pump ceases when the gap in the star wheel comes opposite the cam pins 31.

Title: Method of making conductive circuit patterns by intaglio process
IPC: H05K3/20
Filed: 1968-01-13
Abstract: Selected areas of an insulating substrate are coated with metal to form printed circuits by coating the raised areas of an intaglio plate with metal, applying adhesive repellent to the plate depressions, applying further adhesive repellent to ensure that the raised areas are accurately defined by the repellent, applying a surface of the substrate coated with adhesive to the plate so that the metal coating adheres to the substrate, and separating the substrate and the metal coating from the plate. The substrate is preferably a partially cured laminate of glass cloth and epoxy resin which is applied to the intaglio plate under heat and pressure. The metal coating, e.g. of copper is applied by electroplating. Before the further repellent is applied the copper metal coating may be oxidized, the further repellent applied over the entire plate, and the oxidized metal and the repellent thereover only removed in an acid bath. The intaglio plate is produced by known photographic and etching processes and the plate depressions are coated with porcelain prior to the application of the metal coating The copper coating may be oxidized a second time immediately before the application of the coated substrate in order to increase the adhesion of the copper to the adhesive
Patent ES-359612-A1 (ES)
Title: Picture display arrangement provided with a display tube
IPC: H04N3/185
Filed: 1968-10-26
Abstract: In a cathode-ray tube picture display arrangement a D.C. voltage is automatically applied to a beam intensity control electrode of the tube to increase the intensity of the beam when the EHT voltage exceeds a maximum permitted value. The increase in beam current produces a drop in the EHT voltage and thus prevents damage to the tube and/or the EHT generator and risk of fire attended therewith and also prevents the production of X-ray radiation. Additionally, the increased beam current produced a beam of greater sectional area so that a pale picture lacking in contract results and thus the user is given an indication of a fault condition. As shown, the intensity of the beam of the tube 7 is controlled via an adjustable potential divider 18 connected across a source +V s of fixed voltage and the slider of which is connected to either grid 10 or grid 11. A tap 21 on divider 18 is connected via a diode 19 to a tap 20 on a further potential divider comprising an element 4 having a non-linear current-voltage characteristic and a potentiometer 5 connected across the EHT generator 1. When the beam current is substantially cut-off, e.g. when the video signal represents black or has dropped out, the resulting increase in the voltage at tap 20, when it exceeds the voltage at tap 21, causes diode 19 to conduct so that the beam intensity control grids 10 or 11 receive a higher D.C. voltage and the beam intensity is increased. Due to the non-linear voltage current characteristic of the element 4 the percentage increase in the voltage at tap 20 is several (e.g. five) times the percentage increase in the EHT voltage V h and as the beam intensity nereases the load on generator 1 increases so that the increase in V h is less than it would be without diode 19. The focusing electrode 17 is supplied from a tap on element 4 and variation of the EHT voltage V h with variation in dynamic loading (i.e. variations in the video signal supplied, e.g. between cathode 9 and grid 10) are reduced by means of a known control circuit 6.

Title: Method of making a mechanical joint
IPC: B21D53/04
Filed: 1971-08-19
Abstract: A method and apparatus for joining two or more sheets of metal together and the composite metal blank and mechanical joint produced thereby. A punch and die apparatus is employed wherein a slug is extruded from a first sheet and embedded in a hole provided in a second sheet by the punching action of the slug. The punch never contacts the die itself and the resulting joint is between the slug from the first sheet and the second sheet in which it is embedded. The slug formed from the second sheet is sheared from the composite. By performing this operation in opposing corners of the two sheets, the sheets are secured together so as to prevent relative motion between them. The invention is particularly applicable to the formation of composite metal blanks having a pattern of stop-weld material sandwiched between the sheets.
