Title: Cathode-ray tube driving circuit
IPC: G01R13/22
Filed: 1972-12-19
Abstract: 1409580 D.C.-D.C. converters MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Dec 1972 [23 Dec 1971 24 Dec 1971 (3)] 58664/72 Heading H2F [Also in Division H4] In a cathode-ray tube system in which the E.H.T. voltage is derived by rectifying fly-back pulses and a focusing voltage is derived via a potential divider from the full E.H.T. or, when a voltage multiplier rectifier is employed, from an intermediate tap on the latter a desired ratio between the focusing voltage and the E.H.T. voltage is maintained, despite variations in the beam current of the tube, by producing a voltage the magnitude of which varies with variation in the beam current and combining this voltage with the voltage across the potential divider to produce a focusing voltage the ratio of which with respect to the E.H.T. voltage decreases as the beam current increases. Fig. 3 curve b shows this characteristic in comparison with the characteristic, curve a, of a prior cut system which is described with reference to Figs. 1, 2a and 2b (none shown). Fig. 4 shows a first arrangement in which the voltage developed across resistor 13 and which varies with variation in beam current Ib is combined with the voltage at terminal F of a three-stage multiplier rectifier 8 (supplied with fly-back pulses from fly-back transformer 7) via a potential divider network comprising resistors 10, 11, and 12 to provide the required focusing voltage VF<SP>1</SP>. In operation, when the beam current increases, the E.H.T. voltage VA and the voltage at terminal F decrease whilst the voltage across resistor 13 increases. Thus when the latter voltage is combined via the resistor chain 10, 11, 12 and by suitable adjustment of resistor 12 the rate of decrease in the voltage VF<SP>1</SP> may be made greater than the rate of decrease in VA so that the ratio VF<SP>1</SP>/VA decreases with increasing beam current. Variations of this circuit in which various ones of the capacitors in the multiplier rectifier 8 are removed are described with reference to Figs. 6 to 9 (none shown), and a further variation in which the resistor chain 10, 11, 12 is replaced by a similar resistor chain connected to terminal A is described with reference to Fig. 10 (not shown). Fig. 11 shows a second arrangement in which the voltage which varies with variation in beam current is derived by means of a rectifier 21 (such voltage being also usable as the screen voltage for the tube) and variations of this embodiment in which a two-stage multiplier and a single rectifier stage are employed are described with reference to Figs. 13 and 14 (neither shown). Fig. 12 shows a third arrangement in which the current dependent voltage is produced by means of a tertiary winding 7a and Fig. 15 shows a fourth arrangement in which such voltage is produced across a resistor 31 in series with the secondary winding of transformer 7. A variation of this latter arrangement in which the multiplier-rectifier 8 is replaced by a single rectifier stage is described with reference to Fig. 16 (not shown).

Title: Improvements in or relating to the manufacture of naphthenic hydrocarbons by hydrogenating the corresponding aromatic hydrocarbons
Inventor: JACQUES GABRIEL
IPC: C07C5/10
Filed: 1969-12-05
Abstract: 1,247,278. Hydrogenating aromatics. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 5 Dec., 1969 [9 Dec., 1968], No. 59562/69. Heading C5E. The hydrogenation of aromatic hydrocarbons to naphthenes, e.g. of benzene to cyclohexane, in a liquid phase containing a suspended catalyst, e.g. Raney nickel, is carried out in two elongated and substantially vertical zones located one above the other, the lower zone consisting of a plurality of passageways and acting as a heat exchanger, liquid flowing downwardly through said zones and being externally recycled, and hydrogen gas flowing upwardly, 70-100% of the total H 2  being introduced into the upper zone and 0-30% into the lower zone. When liquid circulation is stopped for any reason, hydrogen is introduced into the bottom of the lower zone to prevent blockage of tubes by catalyst grains. In Fig. 1, circulating liquid comprising mainly cyclohexane plus suspended catalyst enters upper zone 3 from line 13 and descends to lower zone 7 before recycle via line 11 and pump 12. Benzene is introduced via line 1, and hydrogen through lines 2 and 10. Excess hydrogen and product cyclohexane vapour are withdrawn through pipe 6. Fresh catalyst may be introduced from lock chamber 14, the operation of which is described in detail. Lower zone 7 is cooled by coolant liquid, e.g. water, entering at 8 and leaving at 9. In preferred operation the benzene : cyclohexane weight ratio in the liquid phase is below 0À001/1.

Title: Variable high frequency frame antenna
IPC: H01Q7/00
Filed: 1978-12-12
Abstract: The Variable High Frequency Frame Antenna is a device for the reception of wireless signals on all frequencies from 3500 to 28000 K.Hertz and for transmission of wireless signals on the 80, 40, 20, 15 and 10 metre Amateur Bands. It consists of a frame twentyone inches square having wound thereon four turns of 16 SWG wire. The frame is tuned to the desired frequency by means of two 250 pfd variable capacitors C1, C2, coupled up to two seven turn inductances L1, L2, which in turn are link coupled to the frame antenna via a link coil L3 having four turns. Reception and transmission of signals is achieved in the range 3500 to 28000 K.Hertz without the necessity of changing-tuning inductances or capacitors. The frame can be rotated and, therefore, acts as a beam when used for transmission purposes. <IMAGE>

Title: Guest-host liquid crystal display
IPC: G02F1/137
Filed: 1979-06-19
Abstract: In a display system comprising a quarter wave plate 21 between a reflector 22 and an electro-optic dichroic guest-host liquid crystal cell 10-13, the (non-absorbing) background areas of the liquid crystal layer 13 have a homotropic alignment at both cell plates whereas display regions 18 are homogeneously aligned at one or both plates, and the liquid crystal has positive dielectric arisotropy. There is thus a contrast between regions 18 and background areas where the cell is not suited, which is destroyed by a field E between associated electrodes 14, 15, although the latter are absent from any regions 18 arranged for a permanent display. Further portions of the display may be of the type requiring the pressure of a field to produce contrast. The liquid crystal material is nematic; if it contains an optically active additive the layer thickness must be below a critical value. Homotropic aligning layers 20, 23 are of surfactant or produced by cathodic sputtering or vapour deposition; layer 20 partially overlies a continuous homogeneous aligning layer 19 produced by rubbing or vapour deposition. <IMAGE>
