Title: Improvements in or relating to electrical filter circuits
IPC: H03H7/01
Filed: 1933-10-27
Abstract: 420,255. Impedance networks. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and FARREN, L. I., c/o General Electric Co., Wembley, Middlesex. Oct. 27, 1933, No. 29876. Drawings to Specification. [Classes 40 (iii) and 40 (v)] Relates to systems in which either the input terminals or the output terminals of a number of filters are connected in parallel, and comprises means for neutralizing the reactive component of the impedance presented by the group of filters as a whole. For instance, in a set of filters whose input terminals are connected in parallel for the purpose of separating the channels in a multiplex voice-frequency telegraph system, the impedance facing the amplifier which feeds the system should be a constant resistance. Each individual filter offers substantially this resistance within its pass range, but any given frequency lies outside the pass range of all but one of the filters. The remaining filters therefore produce at this frequency a reactive component in the total impedance. This is neutralized by connecting in parallel a reaction network whose impedance is substantially equal and opposite at all frequencies to the reactive component of the existing impedance, so as to produce an antiresonant effect. Two examples of a network suitable for use where twelve harmonic channels are used and comprising two inductances and a condenser are given in the Specification.

Filed: 1971-09-20
Abstract: 1362192 Inductive signalling CABACHIN Ltd 20 Sept 1971 [22 June 1970] 30150/70 Heading H4U In a remote control system comprising a transmitter and receiver operating in the V.L.F. range and coupled via an aerial or magnetic induction field set up by a coil, the transmitter described includes an oscillator with a tuned circuit including an inductor wound on a ferrite rod producing an inductive field and a multivibrator switches the transmitted frequency between two values. At the receiver, Fig. 2, the signal is picked up by a ferrite rod aerial in a tuned circuit 20, amplified (TR 10  to TR 13 ) and supplied to a discriminator circuit 21, 22 tuned to the two received frequencies or a harmonic thereof. Each tuned circuit is associated with a detector (23, 24) and an alternating current at the switching frequency appears at point 25 which is rectified in a voltage doubler circuit D11, D12. By suitable choice of the circuit components the arrangement may be made responsive to a particular switching rate. The output of the voltage doubler is supplied via a Darlington pair TR14, TR15 to a relay RL for controlling external circuitry. The drop across diode D10 ensures that the diodes D11, D12 operate at maximum sensitivity. In a modification, Fig. 3 (not shown), the output of the discriminator is rectified by a single diode and supplied via a filter to operate a relay. Several switching rates may be used at the transmitter to co-operate with a number of discriminators each responsive to a particular switching rate.

Title: An Arrangement for Application of Text in Television Transmission.
IPC: H04N5/278
Filed: 1967-06-30
Abstract: 1,198,657. Television. SVERIGES RADIO A.B. 30 June, 1967 [20 July, 1966], No. 30215/67. Heading H4F. The invention relates to an arrangement for producing a composite picture in which a television picture 10, Fig. 1, is blanked over an area 12 to produce a dark background against which there is displayed a text 11 of bright letters, the arrangement being characterized by the use of counters which respond to the text signal to measure the height 15 of the text and so control the picture blanking that the text is properly located within the background with blank areas 13 and 14 above and below the text. In Fig. 2, the picture signal, which appears on lead 30, is blanked in a circuit 27 and has the text signal, which appears on lead 16, added in a mixer 32 The presence of a text signal is detected by a counter 23 which responds to the first (i.e. top) line of text and makes a count of picture lines corresponding to a complete frame less the number of lines (typically two or three) corresponding to area 13. At the completion of the count an output pulse is produced which initiates operation of a second counter 25 which responds to the text signal applied over lead 33 and functions to measure the height of the text. A signal to control blanking stage 27 is produced on lead 26, the signal commencing with the pulse from counter 23, lasting throughout intervals corresponding to areas 13, 15 and persisting for a further interval (four lines) corresponding to area 14. To allow for texts occupying two lines another counter 40 is provided which functions in the same manner as counter 23 to control counter 25 but is arranged to respond to the text signals corresponding to the second line. To this end the text signals are applied to the counters 23 and 40 by way of a change-over switch 21, 38 which is operated after the first line of text by counter 35 which responds to the text signal. Picture drive pulses on lead 34 reset counter 35 and switch 21, 38 at the end of each picture. The text and picture signals are synchronous but the text-signal may be applied to lead 16 at a time during the picture interval such that the first signal to appear does not correspond to the top of the first line of text. This will cause operation of counters 23 and 40 at the incorrect times and produce faulty reproduction of the text. To prevent this the text signals are applied via a gate 17 which is controlled by the picture frequency pulse so that the gate transmits in response to a picture drive pulse only after text signals have appeared on lead 16.
