Abstract: 1,117,924. Automatic frequency control systems; adjusting tuned amplifiers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 27 Aug., 1965 [29 Aug., 1964; 31 Aug., 1964 (2)], No. 37008/65. Headings H3A and H4L. A receiver I.F. amplifier 33, Fig. 5, is tuned by providing equal amplitude inputs to the amplifier at a number of frequencies fs 1 -fs n  and measuring the outputs at these frequencies by means of filters 34 and detectors 35, the detected outputs being combined and used to control servomotors M which adjust the tuning controls of the amplifier. The detectors 35 provide both positive and negative outputs, and these are combined in units 37 in accordance with a matrix equation corresponding to the required amplitude/frequency characteristic of the amplifier. In a modification, Fig. 7 (not shown), adjustable normalizing units (55) are provided between the filters (54) and the detectors (56). These normalizing units can be adjusted to give zero output to the servomotors when a standard amplifier with the required amplitude/frequency characteristic is inserted in the circuit. This makes it easy to adapt the circuit to different amplitude/frequency characteristics.

Title: Chrominance signal processing apparatus
IPC: H04N9/73
Filed: 1966-08-23
Abstract: 1,092,498. Colour television. HAZELTINE CORPORATION. Aug. 23, 1966 [Dec. 30, 1965], No. 37691/66. Heading H4F. In a colour television receiver in which three colour difference signals (R-Y), (B-Y) and (G-Y) are applied to a colour image reproducing device, e.g. to the grids of a three-gun tube, the D.C. component of a selected one, i.e. (G-Y), of the colour-difference signals is suppressed. In addition the D.C. components of the (R-Y) and (B-Y) may be partially attenuated by predetermined amounts. According to the Specification this elimination of full D.C. stabilization or D.C. restoration in all of the colour difference signal paths does not appreciably degrade the subjective quality of the reproduced colour image. In a first embodiment, Fig. 3, the D.C. component of (G-Y) is suppressed by A.C. coupling it to the green control grid of the tube by means of series coupling capacitor 18. Since this also blocks the D.C. operating bias which is normally supplied to the green grid along with the (G-Y) signal, a fixed D.C. operating bias is supplied by voltage divider 19, 20. This fixed bias must be selected to provide proper reproduction of the grey-scale during monochrome reproduction. In this embodiment the full D.C. and A.C. components of the (R-Y) and (B-Y) signals are coupled to their respective control grids, but in a second embodiment, Fig. 4, not shown, the D.C. components of the (R-Y) and (B-Y) signals are partially attenuated by means of partial D.C. coupling networks (22, 23, 24) and (21, 25, 26) placed in both the signal paths to the red and blue grids of the colour tube. In a third embodiment, Fig. 5, not shown, grey scale balance is ensured by developing a D.C. bias for the green grid directly from the output circuits of the (R-Y) and (B-Y) demodulators in the chrominance signal decoder since if in the arrangement of Fig. 4, not shown, variations of the D.C. operating conditions of the receiver occur the D.C. voltages applied to the red and blue grids would change, but the D.C. bias applied to the green grid would remain constant.

Title: Aquasols of uranium trioxide or uranium trioxide and zirconium dioxide
IPC: C01G43/00
Filed: 1965-09-03
Abstract: Aquasols of UO3 or of UO3 and ZrO2 are prepared by replacing cations from a dispersion in water of an alkaline-precipitated diuranate or of an alkaline-precipitated diuranate/zirconia coprecipitate by hydrogen ions, and simultaneously or subsequently heating the dispersion at a temperature of 60 DEG  to 150 DEG  C. until peptization occurs.  The cations are preferably removed until the dispersion has a pH of 5 to 7.  Cations may be removed by an ion exchange resin in the hydrogen form in which case the dispersion may be heated for at least one hour at 80-110 DEG  C., or by electrodialysis.  The dispersion of the diuranate or the diuranate/zirconia coprecipitate may be obtained by mixing a solution of a uranyl salt or of a uranyl salt and a zirconyl salt with an alkaline precipitating agent, separating the precipitate, washing it substantially free from electrolytes and dispersing the washed precipitate in water.  The uranyl and zirconyl salts are preferably of monobasic acids and the precipitating agent may be ammonia, ammonium hydroxide, an alkali metal hydroxide or an amine having a base constant (Kb) greater than 1 x 10-8. The amount of diuranate or diurante/zirconi in the dispersion thereof is preferably such that the aquasol produced contains 1 to 12% by weight of solids.  A UO3 aquasol produced according to the invention contains particles of size 3-250 mm . A UO3/ZrO2 aquasol produced according to the invention contains particles at least 90% of which are less than 500 mm  in diameter, and in which the molar proportion of ZrO2 may be 1-80%.  The UO3 or UO3/ZrO2 particles can be separated from the aquasols by, e.g., evaporation in vacuo or centrifuging.  Reference has been directed by the Comptroller to Specification 924,999.

Abstract: 1398019 Semi-conductors MITSUBISHI DENKI KK 9 Aug 1973 37864/73 Heading H1K [Also in Division B6] Undercutting of the lower layer 2 is prevented during etching of a window through superimposed layers of silicon dioxide 2 and silicon nitride 3 on a silicon substrate 1 by using a " Freon " (Registered Trade Mark) gas plasma as the etchant, since this attacks the upper nitride layer 3 more readily than it attacks the lower oxide layer 2. If a layer of polycrystalline silicon is applied to the nitride layer 3 undercutting is still avoided, since the plasma attacks the polycrystalline layer at an even higher rate. Examples of Freons are CHClF 2 , CCl 2 F 2 , C 2 Cl 4 F 2 , C 2 Cl 2 F 4 , and C 2 F 6 , optionally mixed with an inert gas. A mask 7 of aluminium or photo-resist is used to define the window.

Title: Encapsulated emulsions and processes for their preparation
IPC: B01J13/10
Filed: 1959-11-09
Abstract: Particles of a primary emulsion of an oil in a hydrophilic liquid containing a thickening agent are encapsulated by a process wherein the said primary emulsion is dispersed to form a secondary emulsion in an aqueous dispersion of at least two concervating colloids at least one of which is a gelable hydrophilic colloid and at least one is an isoelectric colloid (and optionally containing a thickening agent) at a temperature above the gel point of the gelable colloid and causing coacervation of the colloids on to the primary emulsion particles, e.g. by the addition of water or alteration of pH of the coacervating medium. Suitable thickening agents are materials which are substantially insoluble in the oil phase of the primary emulsion and are capable of imparting lipophilic character to the surface of the external phase of the primary emulsion; e.g. acacia, tragacanth, methyl- and carboxymethyl-cellulose, magnesium aluminium silicate, polyglycols, glycerine and syrups.  As suitable colloids there are mentioned gelatine, agar-agar, albumen, alginates, casein, pectins, acacia, starch, fibrinogen, starch-, cellulose- and amylose-acetate phthalate.  The primary emulsion may also contain a conventional emulsifying agent and either or both phases thereof may contain dissolved or suspended material which confers on the products of the invention uses as, for example, sustained release fertilizers, plant growth hormone preparations, bactericides, pesticides, ingredients for pre-mixed foods, vitamin preparations suitable for addition to dry cereal preparations, ingredients of cosmetic preparations, pharmaceutical preparations for oral, topical or injectable use (particularly of the sustained or delayed release type).  Specific examples relate to capsules comprising urea, alizarin cyanide green, methyl neopolamine bromide and hexachlorophene.  Details of the process used are given.
