Patent ES-289491-A1 (ES)
Title: Electrical apparatus
IPC: H03K3/57
Filed: 1963-06-28
Abstract: A pulse generator, e.g. for the ignition system of an internal-combustion engine, comprises a capacitor 21 which is charged resonantly from a D.C. voltage supply through the primary winding of a transformer 17 and periodically discharged resonantly through the series combination of an inductor 25 and a silicon controlled rectifier 26 to whose gate electrode there are applied regularly recurring triggering pulses derived from a relaxation oscillator 54. In the circuit described the pulses developed at the secondary of the transformer 17 are applied through rectifiers 32 to build up incrementally the charge on a capacitor 35 until a discharge gap 37 breaks down whereupon current flowing in the primary winding 42a of step-up transformer 43 induces a sufficient voltage in the secondary 46 to cause spark-gap 50 to break down. The capacitor 35 is then discharged through the gap and the cycle recommences. Triggering pulses for the SCR 26 are derived from a relaxation oscillation 54 comprising timing circuit 56, 57 and unijunction transistor 61, the output pulses therefrom being applied to the gate electrode of the SCR 26 via transformer 74 and D.C. restoring diode 79. Commencing with capacitor 21 initially discharged, the capacitor charges resonantly to rather less than twice the D.C. voltage via the transformer 17. The SCR is then switched on and the capacitor discharges through the inductor 25 to a negative voltage of smaller value. When current in the inductor 25 attempts to change sign the SCR turns off, and a capacitor again charges through the transformer 17 but to a greater voltage than previously as it commenced from a negative voltage. Hence the amplitude of the voltage swing across the capacitor, and likewise across the primary winding of transformer 17, increases until limited by IR losses in the circuit, these being provided in the charging circuit by resistor 15. Where the voltage supply is of low value (e.g. less than 30 volts) so that there is little danger of overloading SCR 26, limiting resistor 15 may be omitted.

Title: Improvements in or relating to activated thermionic sources and to a method of producing same
IPC: H01J49/16
Filed: 1965-03-27
Abstract: A thermionic ion source for use in a mass spectrometer comprises a heating filament coated with a porous layer of an activating substance, which increases the work function of the filament surface, and an outer layer containing a mixture of the activating substance with the sample to be analysed. In particular, a Pt, Re or W filament may be coated with a refractory substance having poor thermal and electrical conductivity, which may, for example, be one or more of MgSiO 3 , ThSiO 4 , SiO 2 and ZrO 2 in the form of a hydrated gel. A heating current is passed through the filament to evaporate the water from the hydrated gel and leave a porous layer of the activating substance on the filament surface, which is then charged with the outer layer and subjected to a further calcination. The thickness of the filament coating may be 0À2 to 1 mm., e.g. 0À5 mm. The product to be analysed may be galena, zircon or other ore containing traces of Pb. The source may also be used in the isotopic analysis of other elements, e.g. U or Th.

Filed: 1968-05-08
Abstract: A machine which makes and fills tetrahedral packages with, e.g., milk, comprises a vertical welding jaw 3 which effects longitudinal sealing of a folded and slightly flattened plastics or plastics-metallic paper sandwich sheet 6, when around a package filling tube 8, so forming a sheath 7 which is fed between upper and lower horizontal welding and cutting jaws 10, 12 by a vertically displaceable horizontal clamping jaw 4. The upper jaw 10 is displaced 45 degrees from the longitudinal seam and the lower jaw 12 is at right-angles to the upper jaw. The filling tube 8 is connected to a constant level reservoir 9 via a syphon 13. The horizontal clamping jaw 4 is mounted on coaxial jacks 15, 16, Fig. 6, so that activation of the jack 15 causes the jaw 4 to move the sheath 7 a distance equal to twice the distance separating the welding and cutting jaws 10, 12, whereupon the lower jaw closes just before the upper jaw 10, whilst activation of the jack 16 between the successive jaw closures effects a slight downward displacement of the sheath to compensate for sheath deformation during welding. An optional additional horizontal clamping jaw (14), Fig. 2 (not shown), can be used beneath the lower jaw 12 to initially hold the bottom seal in position.

Title: Electron beam deflection and high voltage generation circuit
IPC: H03K4/83
Filed: 1969-04-12
Abstract: In a deflection circuit for a cathode-ray tube, a first bi-directional switching means 24 is arranged to be conductive during the forward stroke so as to connect deflection coil 22 across an energy supply device 23 and a second switching means 46 arranged to become conductive towards the end of the forward stroke, the switching means 24, 36 being coupled via a T- network comprising capacitors 29, 30 and inductor 28. As described, diode 26 is arranged to be conductive at the beginning of each trace so that a deflection current is driven by the large capacitor 23 through the deflection coils 22. Soon after the beginning of each forward stroke, a pulse is induced in winding 31 and fed to the gate of thyristor 25 so that the anode/cathode path becomes conductive when the deflection current passes through zero midway through each forward stroke 8 Ás before the end of each forward stroke, thyristor 37 is turned on by a pulse from the horizontal oscillator 19 so that energy which has been stored into capacitors 29 and 30 is circulated resonantly via circuits including components 24, 29, 28, 36 and 36, 28, 30. This provides a reverse current in thyristor 25 so that after the stored carriers have been dissipated, thyristor 25 becomes turned off, terminating the forward stroke. The resonant current now continues via diode 26 until a further reversal occurs when that diode is also turned off. Energy is thus returned to capacitor 23. Further current reversal similarly turns off thyristor 37 and (later) diode 38 so that a further forward stroke can start. The flyback pulses induced in transformer 43 (tuned to approximately the third harmonic of the flyback frequency) are rectified at 44 to provide E.H.T. for the cathode-ray tube. Circuits 46 ... 50 protect the circuit against E.H.T. flash-over. Capacitor 30 is arranged to resonate with its associated inductance at twice the flyback frequency. Stabilizing image width.-The exchange of energy between transformer 43 and the rest of the circuit is arranged so that, following variation in cathode-ray tube current, the corresponding change in deflection current is approximately one half the change in E.H.T. voltage so that the image width remains constant.
