Patent ES-351521-A1 (ES)
Title: Three-element electron discharge tube
IPC: H01J21/18
Filed: 1968-03-13
Abstract: A high vacuum electronic valve comprises an elongate control electrode 1 surrounded by an anode 4 which has a number of spaced elongate recesses 7 extending parallel to the control electrode, an elongate cathode 9 disposed in each recess, an arrangement (not shown) for generating a magnetic field to reduce the number of electrons reaching the control electrode, and a pair of plate-like separator electrodes 31, one located either side of the cathode 9 in each recess. The penetration A of the separator electrodes 31 into the space between the anode and control electrode is set by the requirement that when there is no current flowing, the desired valve amplification factor is equal to the ratio of the electric field strength generated at the cathodes per unit control voltage to the electric field-strength generated at the cathodes per unit anode voltage. As shown, the separator electrodes 31 are formed by a single U-shaped cylindrical unit, each fastened to a rod 16 which forms a part of the cathode tensioning frame comprising plates 10 to 14 and rods 15 to 17 and a spring 23 to hold the cathodes under axial tension. To provide the magnetic field a solenoid coil may be coaxially disposed around the anode 4, and the valve may be cooled by a coolant, e.g. water, flowing in the annular gap between the solenoid coil and the anode 4, which may have cooling fins. An additional grid-shaped control electrode (41), Fig. 4 (not shown), may be arranged between each cathode and the control electrode in the region between the separator electrodes of a respective cathode. An alternative embodiment, Fig. 3 (not shown), has two concentric cylindrical control electrodes, one inside and the other outside the anode, with the anode recesses extending through the anode wall and extended plate separator electrodes so that an electron stream is emitted from either side of the cathode.
Patent ES-351880-A1 (ES)
Title: Apparatus for joining wires
IPC: H01R43/042
Filed: 1968-03-22
Abstract: A method of joining together first and second lengths of insulated wire comprises placing the first and second wires into and along the length of a metallic clip of trough-like form so that the free ends of the wires extend beyond opposed ends of the clip, cutting off the free ends of the wires and deforming the clip to grip the first and second wires, the clip having integeral insulation piercing means which make electrical contact with the wire through the insulation. The clips are stored in a spring-loaded magazine 13 and retained in the operating position against the action of the spring by projections 25, 26. The wires to be joined are laid in the clip in a crossed formation, the positioning of these wires being facilitated by vertical separators (29a), (29b), Fig. 7 (not shown), at each side of the clip which define V-slots 30, 31, the free ends of the wires being placed in the deeper slot 31. The operator holds the free end of each wire and he then depresses a foot pedal which is connected to a punch 16 by a cable to move the punch towards a die 15. A blade 18 separates the top clip from the rest in the magazine, the clips being held together adhesively. Further movement of the punch causes spring-loaded notched heads 21 to engage the wires and tension them against the pull of the operator. When fully tensioned knives 19 cut off the free ends of the wires and the heads 21 spring forward pulling the ends of the wires inside the clip. As the ends of the wire are being drawn into the clip it is crimped by the punch 16 against the die 15. Another type of machine is provided with a horizontal magazine (13), Fig. 11 (not shown), and has a foot-operated Bowden cable 28 actuating a pair of beaked jaws 34, 35 via a series of lever arms. Depression of the foot pedal causes a member 40 to break the adhesive joining the end clip and lifts it to the operating position. Wires are placed one on each side of vertical separators (38), (39), Fig. 11 (not shown). Further depression of the pedal allows blades attached to the jaws to cut off the free ends of the wires prior to crimping, the jaws folding over the sides of the clip and finally clamping home the edges over the wires. The wires are individually crimped by each side of the clip, Fig. 4 (not shown). In a third form of connector, the wires are laid in the clip which is then closed between flat jaws. The remounted ends are cut off by cutting edges 12. The connectors, which may be of hard brass or phosphor bronze, are mounted end to end on a strip of insulating material prior to use.

Title: Stacking apparatus for plastics material sheeting
IPC: B65H29/58
Filed: 1968-07-04
Abstract: Sheets W, Fig. 1, cut from a web 38 by cutters 37 are gripped by their leading edges by grippers 10a or 10b, Figs. 1 and 2, on pairs of chains of conveyers 1, 2 while the conveyers pass over rollers 5, 6, each conveyer having grippers along only half its length and the grippers on one conveyer passing the charging zone while the blank part of the other chain passes. The sheets are carried on the lower runs of the conveyers 1, 2 respectively over transverse belt conveyers 11, 12, on to which they are dropped to form stacks when the grippers open and while the conveyers 11, 12 are stationary. When the required number of sheets are in a stack, and while the blank part of the conveyer 1 or 2 is passing, the conveyer 11 or 12 is put into motion to move the stack away. The conveyers 11, 12 may move in opposite directions, or may move to the same side of the conveyers 1, 2 at different angles, or at the same angle, and in the last case the stacks on the conveyer 11 are deposited on the longer conveyer 12, either on to or between the stacks thereon. A deflector plate 40 is moved to the left when a sheet is gripped to prevent the sheet fouling the next gripper. The grippers each comprise a fixed jaw 23, Fig. 4, and a movable jaw in the form of a pin 25 urged by a spring 26 to closed position and opened by stationary cams 33, 34, 341 acting on rollers 32.

In a modification, Fig. 6 (not shown), the ridges (64, 66) are made separately from the web (68). The retainer may be of sheet metal and the sealing elements may be of rubber or plastics, such as vinyl polymers or copolymers, urethanes, olefines or epoxy resins.
Patent ES-366374-A1 (ES)
Title: Polymerization monitor
IPC: C08F297/02
Filed: 1969-04-23
Abstract: A process for monitoring the concentration of living polymer chains in a homogeneous solution polymerization reaction mixture comprises removing a stream therefrom, treating a portion of the stream with a de-activating agent to produce a de-activated reference portion, and comparing the light absorbance characteristics of the reference portion with those of a second, active portion of the stream at the same narrow band wavelength of transmitted radiation. The results may be shown graphically or used to control and modify the polymerization process, particularly in relation to molecular weight and-distribution. In the preferred procedure, samples are removed from polymerization zone 10 and passed in part via line 18 to cell 30 and in part via line 16 to cell 28. Light from source 34 passes via filter 36 to cells 28 and 30, and thence via filters 42 and 44 to photo-tubes 46 and 48, the output from which is fed to control or record station 50. The sample portion flowing in 18 is de-activated from store 20 via line 22. Partial de-activation of the sample portion flowing in 16 may also be effected via line 26. The process may also be applied to monitoring the purification of reactants prior to polymerization. In examples, polybutadiene, polyisoprene, butadiene-styrene random and block copolymers are prepared using butyl lithium initiator in cyclohexane or cyclohexaneisopentane mixture. Analogous monomers, solvents and initiators are-stated in one example to give similar results.
