Title: Improvements in or relating to electric sawtooth voltage oscillation generators
IPC: H03K4/43
Filed: 1952-07-06
Abstract: 741,600. Automatic control systems. GENERAL ELECTRIC CO., Ltd., and GLEDHILL, G. A. July 6, 1953 [July 9, 1952], No. 17365/52. Class 38 (4). [Also in Group XL (c)] The invention relates to saw-tooth generators more particularly for radial scanning circuits, of the type.in which a sine wave voltage is applied to an integrator circuit associated with a clamp which when periodically rendered inoperative permits the integrator to generate a long flank, the magnitude and polarity of which depends on the instantaneous value of the sine wave. In order to maintain the D.C. level of the output wave constant a D.C. feed-back circuit is provided to control the reference level to which the integrator is clamped. The Figure shows a Miller integrator circuit V3, C2 generating saw-tooth waves at its anode which are applied directly and through a paraphase amplifier V4 to a push-pull output circuit V5, V6. The sine wave is applied via terminal T2 to the charging resistor R2 but is normally rendered ineffective by a normally conductive clamp circuit VI, V2 through which valve V3 is biased to the centre of its characteristic. The anode of the integrator valve V2 is connected through a D.C. negative feed-back path including V4, V7, V8 and V2 to its grid to control the reference level of the clamp circuit. When a negative pulse is applied to terminal T 1 to cut off the clamping valves V1 and V2 and thus to permit the saw-tooth to be generated, the output voltage at the cathode of valve V8 might rise to such a value as to render valve V2 conductive and to avoid this a voltage limiter comprising a rectifier W1 and potentiometer R5 and R6, is provided. The clamping circuit may be replaced by one of diode type (Fig. 2, not shown) and the valves V4 and V7 may be omitted from the feed-back path or may be replaced by a cathode-coupled pair. Variation in amplitude and duration of the scan may be effected by changing the value of the integrating capacitor C2 and the duration of the input pulses. According to the Provisional Specification the feed-back may alternatively be applied through a cathode follower to the cathode end of the cathode bias resistor of the integrator.

Title: Barium titanate dielectric
IPC: C04B35/468
Filed: 1954-06-14
Abstract: A barium titanate dielectric includes the addition of iron and calcium, the addition comprising less than 4 per cent by weight and the iron and the calcium each exceeding 0.3 per cent by weight.  It is stated that by the use of this additive, the effect of aging on the dielectric constant is considerably reduced whether the barium titanate is in cubic or tetragonal crystalline form.  Further, with barium titanate in cubic form a marked reduction in temperature variation of dielectric constant, dielectric losses and piezo-electricity can be achieved.  To prepare a dielectric having a cubic crystalline form, barium p  titanium oxalate is prepared from commercial grade barium chloride, titanium tetrachloride and oxalic acid.  The precipitate is washed after it has been allowed to stand in the solution, for e.g. 16 hours, to achieve an optimum crystal size. The barium titanium oxalate is then calcined at a comparatively low temperature (600-1000 DEG C.), to convert it to barium titanate powder having a cubic structure.  Suitable iron and calcium additives (e.g. metallic iron and calcium or ferric oxide, calcium oxide, calcium fluoride or calcium carbonate), are then added to the barium titanate powder and the mixture is then fired at a high temperature (e.g. 1350 DEG C.), to convert it to a ceramic form. It is stated that the iron and calcium additives have the effect of inhibiting the formation of a tetragonal crystalline structure during the final firing process.
