Title: Varactor diode circuit adjustment
IPC: H03J3/18
Filed: 1968-04-04
Abstract: 1,224,185. Testing radio receivers; oscillators. INTERNATIONAL STANDARD ELECTRIC CORP. 4 April, 1968 [12 April, 1967], No 16163/68. Headings H3Q, H3T and H4L. A radio receiver circuit comprises a varactor diode C D  and a capacitor C s  in series, shunted by a tapped inductance L to form a bridge across whose diagonal AB an indicator can be connected; on applying a signal to the circuit the capacitance of the varactor diode is varied by a control voltage until the indicator shows zero potential difference between the tapping of the inductance and the junction between the two capacitances. As shown, this method is used for adjusting the local oscillator of a superheterodyne receive for correct tracking. The capacitor C s  is the normal padding capacitance and the tapping A is selected so that it divides the coil into two parts having the same ratio as that of the capacitances C D  (chosen value) and C s . A valve voltmeter or oscilloscope is connected between A and B and the control voltage (applied at G) is varied by resistor R s  until zero voltage exists between A and B. If the coil L has a core this should be removed during the adjustment. The indicator should have a frequency response which does not include harmonics of the oscillator frequency. If it is desired to limit the signal voltage across the varactor diode, the resonant circuit can be damped by connecting R s  across C D . When applied to circuits other than oscillators, a signal voltage is induced or injected across points ED.

Abstract: 1,132,585. Fluorinated phenothiazines, thiophenols, diphenyl sulphides, anilines and benzenes. IMPERIAL SMELTING CORP. (N.S.C.) Ltd. 1 April, 1966 [15 April, 1965], No. 16387/65. Heading C2C. Compounds of the general formula wherein 2-8 fluorine atoms are attached to ring carbon atoms and any remaining portions of rings A and B are unsubstituted or substituted by 1 or more of alkyl, fluoroalkyl, alkoxy, nitro, or a halogen other than fluorine, are prepared by cyclizing a corresponding compound of the formula by heating it with an acid binding agent. The invention also comprises compounds of the general formula wherein each Z group is H, F, a halogen other than fluorine, alkyl, fluoroalkyl, alkoxy or nitro, and X is H or dialkylaminoalkyl. The compounds in which X is dialkylaminoalkyl may be obtained by reacting the corresponding compound in which X is H with a dialkylaminoalkyl chloride. The starting materials of Formula II above may be prepared: (a) by reacting an o-haloaniline (halo being Cl, Br or I) corresponding to ring A with a cuprous ofluorothiophenoxide corresponding to ring B; (b) by reacting a cuprous o-aminothiophenoxide corresponding to ring A with an o-halofluorobenzene (halo being Cl, Br or I) corresponding to ring B; (c) by reduction of corresponding onitro-o<SP>1</SP>-fluoro-diphenyl sulphides, these compounds being obtainable by processes analogous to (a) and (b) above using the corresponding nitro compounds in place of the amines. The cuprous thiophenates are obtained from cuprous oxide and the corresponding thiophenols which are in turn obtained by reacting a fluorobenzene with sodium hydrosulphide to replace a fluorine atom by an -SH group. The o-amino-o<SP>1</SP>- fluoro-diphenyl sulphides may be converted to their N-trifluoroacetyl derivatives for characterization purposes. 2-Bromo-tetrafluoroaniline is obtained by bromination of 2,3,4,5-tetrafluoroaniline. 1,2,4-Trifluorobenzene is obtained by desulphurizing 2,3,5-trifluorothiophenol or 2,3,6- trifluorothiophenol with Raney nickel.
