Title: Improvements in and relating to the manufacture of antimony oxides
IPC: C01G30/00
Filed: 1930-02-04
Abstract: <PICT:0348138/III/1> Antimony oxide is obtained by leading powdered antimony or ores &c. containing antimony into a current of gas or vapour which is then burnt by means of oxygen or air.  Alternatively the powdered material is led into a combustion space and burnt by flames of coal dust, gas, or oil fuel.  Oxide or sulphide ores or impure oxides or mixtures of sulphide and oxide ores may be used in the process.  Reaction may be effected in a pear-shaped furnace a into which combustible gases or vapours or coal dust flames are blown through burners b.  Material to be oxidized mixed with preheated compressed air introduced through e, is introduced into the furnace through d and is held in suspension in the jet of flame. The flaked or finely divided oxide obtained is drawn off at g. Dross which melts is removed at f and may be returned to the process in admixture with concentrated ore.  Specifications 25477/98, [Class 1, Acids, alkalies, &c.], and 163,623, [Class 1 (iii), Oxides &c. Metallic], are referred to.

Patent GB-643998-A (GB)
Title: Improvements in and relating to radio altimeters
IPC: G01S13/34
Filed: 1947-02-11
Abstract: 643,998. Radiolocation; automatic gain concontrol ; valve amplifying circuits. SOC. FRANCAISE RADIO-ELECTRIQUE. Feb. 11, 1947, No. 3985. Convention date, Feb. 13, 1946. [Classes 40 (v), 40 (vi) and 40 (vii)] A frequency-modulation radio altimeter is provided with a circuit to give a control voltage varying inversely with the beat frequency between direct and reflected radio waves, this voltage being fed to the beat frequency amplifier to give it a gain rising with frequency. Thus the lowest beat-frequency present, since it gives the highest control voltage, decides the gain of the amplifier and eliminates errors due to weaker multiple reflections. Also, should the transmission be suppressed, the amplifier is automatically adjusted for maximum gain. Fig. 1 shows a means of obtaining such a control voltage where the output end of the amplifier consists of a valve 1 supplying a rectangular voltage of constant amplitude to a frequency meter via condenser 3. The time constant of condenser 5 and resistor 4 is large compared with the half-period of the rectangular waveform and the consequent saw-tooth voltage across condenser 5 is substantially inversely proportional to the frequency. The condenser 8 with rectifier 6 and resistor 7 convert this to a D.C. voltage which is fed to the controlling device via decoupling resistor 9. Fig. 4 shows a negative feed-back circuit to ensure proper control over a wide frequency range. The feed-back network, comprising resistors 18, 19, 21 and condenser 20, is so designed that the overall amplifier gain characteristic is proportional to the frequency, and a negative control voltage, obtained, for example, as in Fig. 1, is applied to the control grids of valves 10 and 12. Under these conditions the response rises with frequency till the feed-back becomes zero and then the inherent amplifier gain holds, as in the curves of Fig. 2 (not shown). In order to obtain the characteristic curves of Fig. 3 (not shown), in which the gain increases to a maximum and then decreases as the frequency rises further, a condenser 24 is connected across the anode to cathode of valve 10 (thus making the gain of the amplifier, per se, inversely pro. portional to frequency). A further modifica. tion, to reduce the wide range of inherent gain required of the amplifier to produce such characteristics, consists of adding a resistor 25 (Fig. 6, not shown) between resistor 13 and H.T. supply, and connecting a condenser 26 from the junction of these resistors to the cathode of valve 10. These are of such value that the inherent gain of the amplifier is inversely proportional to frequency below a given frequency F4 and condenser 24 is chosen such that its action is only appreciable at frequencies higher than a given value F5. The gain between frequencies F4 and F5 thus remains substantially constant. This results in characteristics having the general form previously described but with less defined maxima, as in Fig. 5 (not shown).

Title: Process of manufacturing chlorinated hydrocarbons
IPC: C07C21/10
Filed: 1950-02-17
Abstract: At least two chlorinated ethylenic hydrocarbons are produced by passing an unsaturated hydrocarbon and at least one chlorinated ethylenic hydrocarbon having at least one hydrogen atom together with sufficient chlorine to effect additive chlorination of both into a chlorinator, followed by dehydrochlorination of the polychlorethanes obtained either separately or in admixture.  In an example, acetylene, trichlorethylene, and chlorine are reacted in a chlorinator, the mixture of tetra- and pentachlorethanes so obtained is dehydrochlorinated in a column with milk of lime to give a mixture of trichlorethylene and perchlorethylene, these two are separated in a rectifying column, and some of the former is recycled.  Similarly, a mixture of mono- and di-chlorethylene is obtained by chlorinating a mixture of ethylene and mono-chlorethylene, followed by dehydrochlorination of the di- and tri-chlorethanes obtained. Specification 604,384 is referred to.

Title: Improvements in cathode ray oscillograph circuit
IPC: G01R13/26
Filed: 1950-02-17
Abstract: 685,556. Cathode-ray oscillograph circuits. DUMONT LABORATORIES, Inc., A. B. Feb. 17, 1950 [Feb. 17, 1949], No. 4177/50. Class 37. [Also in Group XL (c)] An Eccles-Jordan pulse generating circuit in series with the voltage divider supplying the electrodes of a cathode-ray oscillograph functions to brighten the trace or release the beam simultaneously with application of the saw tooth time base sweep to the deflecting plates. As shown, a negative saw-tooth pulse A is impressed on deflecting plates 19 through an amplifier 18 and at the same time applied to the grid 2 of a triode 1 to block this tube and generate a triggering gate voltage of positive sense and the shape as shown at B across its anode load resistor 3. The gate voltage B fed to the input grid 5 of one of the tubes 6 in the Eccles-Jordan or flip-flop arrangement triggers off the circuit and the resultant rectangular positive pulse C taken from the anode of the other tube 7 is applied to the control grid 8 of the C.R.O. 9. The grid 8 thus becomes less negative with respect to the cathode 12 and the beam is intensified for the duration of the saw-tooth time base sweep. The voltage of the cathode 12 may be adjusted by means of slider 10 contacting a resistor 11 in the voltage divider so that the beam is completely cut off in the absence of the brightening pulse C. The Eccles-Jordan pulse-generating circuit is a series element in the voltage divider or bleeder and as shown is interposed between a filter network 25 terminating at H.T. negative and a resistor chain tapped to feed the C.R.O. electrodes and terminating at grounded H.T. positive. The anode resistors 16, 17 in the pulse generating circuit are equal so that the current drawn in the voltage divider is constant in either of the two stable operating conditions. The invention is directed particularly towards cathode-ray oscillographs used in recording transients.

Abstract: 586,262. Valve receiving circuits; aerial coupling arrangements, HAZELTINE CORPORATION. Feb. 21, 1945, No. 4422. Convention date, March 8, 1944. Drawings to Specification. [Class 40 (v)] The coupling means connecting the aerial to a super - regenerative receiver includes an attenuating network to increase the stability of the receiver. When the aerial, transmission line and receiver are not matched, oscillations, generated by the super-regenerative valve, during each quench period, are propagated along the line and reflected back, tending to prevent quenching of the oscillations. By including an attenuating network, the multiple reflections along the line are damped out rapidly, while incoming signal undergo only a single attenuation. The network may comprise a series resistance and a shunt resistance.
