Patent ES-344033-A1 (ES)
Title: Electron beam apparatus having means to selectively utilize a luminescent screen or a photographic plate
IPC: H01J37/22
Filed: 1967-08-11
Abstract: The base 2 of an electron microscope 1 or electron diffraction apparatus contains an aperture 5 which can be sealed by a luminescent screen 6 provided with a sealing ring 11 and spring-biased towards the aperture from a support 8 which is movable axially and rotatable. When the support is moved axially to disengage the screen 6 from the aperture 5, a 90 degrees rotation of the support brings a rectangular aperture 22 in the support above a magazine (31, Fig. 2, not shown) containing photographic plates resiliently urged towards the support so that a plate is inserted into the aperture 22. A further 90 degrees rotation brings the photographic plate opposite the aperture 5, and a further 90 degrees rotation brings the aperture 22 above a disposal bin (34, Fig. 2, not shown) into which the used photographic plate drops. The magazine and the disposal bin may be removed when the microscope is sealed by the screen 6 and air is admitted into the housing 3. If the support 8 is rotated in the opposite direction it does not pick up a photographic plate and the aperture 22 may be disposed in front of the aperture 5 to allow electrons from the microscope to pass to a fluorescent screen arranged in front of a lens system and a vidicon camera tube arranged in a container which can be attached to the apparatus in lieu of the cover-plate 41 (Fig. 4, not shown).

Title: Filter and valve assembly for water circulation systems
IPC: B01D37/02
Filed: 1967-11-30
Abstract: A tank 1 for a filter element comprises a single influent line 10 and a single outlet line 11 and a valve 15 which, as shown, connects line 10 to line 29, and connects line 28 to line 11 respectively for backwashing, but which in a second position (Fig. 2, not shown) connects line 10 to line 28 and line 29 to line 11 for normal forward filtration flow. As described, a bag (41, Fig. 1, not shown) is connected downstream of line 11 for filtering the backwash before returning it to a swimming pool it may be bypassed during normal forward filtration.

Valve member 20 pivots about axis 22 and is surrounded by an O-ring 23 which sealingly engages in grooves 24 in the valve casing.
Patent ES-349998-A1 (ES)
Title: Method and apparatus of production of noncontaminated plasmoids
IPC: H05H1/22
Filed: 1968-01-21
Abstract: In a nuclear fusion device a target of solid deuterium, or solid deuterium-tritium mixture, is subjected to the focused radiation from a spherical charge of TNT, a neutron burst being generated. The radiant energy reaches the target before the impurities formed at the expansion point, thus leaving the plasma generated at the target uncontaminated. The target 20, is located at one focus of the ellipsoidal chamber 10 and the spherical TNT charge 16 at the other focus. Ignition of the charge is effected by the circuit 18 and the radiation energy is reflected by the lining 14 on to the target 20. A wall 21, transparent to radiations may be inserted between 16 and 20, thereby further reducing the contamination of 20 by 16. The explosive may be triggered by a laser beam and a spark gap may be employed to supply the radiation in place of the explosion. The wall 21 may be replaced by a solid ellipsoid which provides screening but does not restrict the pressure distribution.
Patent ES-365327-A1 (ES)
Title: Electronically controlled injection system for an internal combustion engine
IPC: F02D41/36
Filed: 1969-03-27
Abstract: In an I. C. engine fuel injection system, a single control monostable multi-vibrator supplies opening pulses to a plurality of solenoid valves, and at least one storage device is provided to supply a prolongation pulse which immediately follows the basic pulse of the multi-vibrator, the duration of this basic pulse being dependent upon at least one engine operating parameter, e.g. intake manifold pressure, and the duration of the prolongation pulse being dependent upon the duration of the basic pulse. In this way the valves are operated with mutually overlapping injection period. As shown, solenoid valves 21-24 are opened in a desired sequence by switches 11-14, e.g. in the ignition distributer. As each switch is closed, a bi-stable multi-vibrator 32 is triggered which triggers monostable multi-vibrator 33 into an unstable state while applying a signal to one of the AND gates 34 or 39. During the unstable period of multi-vibrator 33 a pulse is applied to a respective valve, via an OR gate 36 or 41 and an amplifier 51 or 52, and the storage device 35 or 40 commences to charge. When multi-vibrator 33 returns to its normal state, the storage device 35 or 40 discharges to provide the prolongation pulse. The storage device may include a capacitor (83), Fig. 3 (not shown), which may be charged and discharged linearly to provide a proportional relationship between the basic pulse and the prolongation pulse, or controlled by an engine operating parameter to provide a desired relationship between these pulses. In an alternative, each valve is provided with a storage device with a distributer, e.g. a logic circuit, connected between multi-vibrator 33 and the individual storage devices. In a modification, Fig. 4 (not shown), the output of each OR gate 36, 41 is split into two channels, each channel containing an AND gate and an amplifier connected to a respective valve 21-24, and the switches 11-14 are connected to respective AND gates in the channels. In a modification of the latter embodiment, Figs. 5-7 (not shown), switching is effected electronically by connecting pairs of switches 11, 13 and 12, 14 to the bi-stable multi-vibrator 32 via respective bi-stable multivibrators (30), (31), the outputs of the latter multivibrators being connected to respective AND gates in the channels. In an eight-cylinder I. C. engine, further valves (25)-(28), Fig.4 (not shown), are connected in parallel with valves 21-24, the valves operating in pairs. In Figs. 8-10 (not shown), two valves or groups of valves are operated which are opened alternatively and whose periods overlap. This injection system is intended for operating a rotary piston engine.

Title: Process and apparatus for the continuous preparation of a spinnable solution of acrylonitrile polymers
IPC: C08F20/44
Filed: 1969-07-30
Abstract: A reactor 3 for the continuous polymerisation of acrylonitrile comprises a column 13 (see Fig. 2) having heating jackets 14 and a reaction mixing system comprising an axially rotatable shaft 15 carrying discs 17 and turbines 16. The discs 17 define "reaction zones" each of which has at least one turbine 16. Two spiral strips 18 of opposite pitch scrape the column wall. The reactor may be split into two or more parts mounted in series, Fig. 3 (not shown). In operation monomer, catalyst and solvent are fed from reservoirs 1, 2 (see Fig. 1) to the reactor 3 and polymer is then passed to 4 where it is stirred and diluted with diluent from reservoir 5. Gear pump 6 pumps the diluted polymer to a horizontal film evaporator 7 where solvent and residual volatile monomers are removed. The solution is then withdrawn by gear pump 8 and its viscosity optionally adjusted by addition of a diluent from reservoir 10 before spinning into yarn.
Patent ES-371682-A1 (ES)
Title: Frame synchronization arrangement for pcm systems
IPC: H04L7/027
Filed: 1969-09-19
Abstract: The decoder produces output containing a detectable signal component equal to one-half the frame repetition rate when an out of sync condition is present. A bandpass filter detects the signal component and produces a pulse which is inserted into the bit clock from which the frame clock is derived for operating the decoder. The frame clock is shifted one bit each frame until a sync condition is achieved and the signal component disappears. A feedback circuit inhibiting the filter output is provided to prevent for a given time interval generating a succession of additional pulses after the first extra pulse is inserted into the bit clock.
