Title: Improvements in and relating to noise suppression in radio receivers
Inventor: FAIRHURST HAROLD ALFRED
IPC: H03G11/02
Filed: 1952-11-25
Abstract: 732,143. Interference-limiting circuits. MURPHY RADIO, Ltd. Nov. 25, 1953 [Nov. 25, 1952], No. 29855/52. Class 40 (6). An interference-limiting circuit in a radio receiver comprises a diode 5 in series with the audio-frequency path having its output connected to a circuit 8, 9 which limits the rate of change of output potential to the highest value in the desired signal, the output also being fed to the next valve 13 of the channel and a diode 6 being provided in shunt with the signal channel and connected to a point in a cathode load 15 of the valve. The time constant circuit 8, 9 will not follow sharp noise peaks and accordingly the series diode blocks when they occur. The cathode voltage of the shunt diode follows the signal content of its anode voltage and on the occurrence of an interference pulse the shunt diode also conducts. It may be arranged that the current applied to the cathode of valve 13 when the shunt diode conducts neutralizes any residue of the interference pulse existing at the grid of the valve. The capacitor 17 makes the signal voltage at the cathode of diode 6 more nearly equal to that at the anode. A further diode 18 blocks on the occurrence of negative voltage peaks. The invention comprises the combination of those described in Specifications 532,521, 639,183 and 639,184 and may be modified such that the D.C. bias on the diodes follows the signal level, as described in these Specifications.

Abstract: 1,091,162. Transistor circuits; pulse modulation circuits. G. & E. BRADLEY Ltd. July 14, 1966 [July 14, 1965], No. 29914/65. Headings H3T and H4L. A chopper circuit, Fig. 1, comprises: two semi-conductor switches in series across a pair of input terminals 13, 14; a capacitor 30 also across the input terminals; a second capacitor 19 connected between the junction of the two switching devices 15, 16 and an output terminal 18; and a control source 21 which renders the two switches alternately conducting with an interval between the conducting periods when neither switch is conducting. The output terminal 18 is connected to an A.C. amplifier 20. During a control pulse of one polarity, capacitor 19 charges through transistor 15 to the potential of a D.C. input source 10 and during a pulse of the opposite polarity, it discharges through transistor 16. The control signal, Fig. 4(e), is derived from a multivibrator, Fig. 3 (not shown), giving two antiphase outputs, Fig1. 4(a), 4(b). These outputs are fed to bi-stable divider circuits which switch on the positive edge of the pulses to produce phase displaced signals, Figs. 4(c),4 (d) The outputs from the dividers are then added to produce the required control signal, Fig. 4(e).

Title: Process for the production of insecticidal compounds
Inventor: BUECHEL KARL-HEINZ
IPC: C07C17/10
Filed: 1962-08-03
Abstract: The invention relates to a process for the manufacture of an octachloro product of 4,5,6,7,8,8-hexachloro-4, 7-methano-3a, 4, 7, 7a-tetrahydroindane (HCMT) by chlorination of HCMT in the presence of a hydrogen chloride acceptor preferably inert to chlorine under the reaction conditions. Suitable acceptors comprise epoxides such as epichlorohydrin; carbonates such as calcium carbonate and sodium bicarbonate; and preferably metallic oxides such as magnesium oxide, calcium oxide, barium oxide, and zinc oxide. The acceptor is usually employed in an amount of 10-100% based on the weight of HCMT. Preferably the chlorination is effected with gaseous chlorine with HCMT solution while the mixture is irradiated with actinic light. The HCMT starting material may be obtained by hydrogenation of the Diels-Alder adduct of hexachlorocyclopentadiene and cyclopentadiene. In an example chlorine was passed into a mixture of HCMT in carbontetrachloride and magnesium oxide whilst irradiated with a mercury lamp and the product isolated. The HCMT used may be obtained by hydrogenating chlordene, dissolved in methanol, with hydrogen at atmospheric pressure for 2 hours at a temperature of 100 DEG C. in the presence of a Raney-nickel catalyst or by Diels-Alder condensation of hexachlorocyclopentadiene with cyclopentene as described for example in Specification 796,675. Specification 794,661 also is referred to.
