Title: Television broadcasting apparatus
IPC: H04N7/173
Filed: 1973-05-11
Abstract: 1436715 Television systems COLUMBIA PICTURES INDUSTRIES Inc 11 May 1973 [12 May 1972] 22607/73 Headings H4R and H4F [Also in Division G4] In a system for the transmission of at least one secure channel signal from a central station to selected receiving station the central station transmits a coded command signal which, on detection at the selected receiving station terminates the operation of a device which interferes with the reception of that channel program. As described the central station of a wired television distribution system transmits a number of programmes, which are to be freely available, on signals to which the receivers can normally be turned together with two programmes, which are not freely available, and are transmitted at a frequency, e.g. in the 25 to 50 MHz band, to which the normal receiver cannot be tuned. At the receiver a selector switch 50 is operable to selected desired programmes, those that are freely available being by-passed direct to the television set input whilst those to which access is restricted are fed to a converter to convert them to a channel frequency to which the television set can be tuned. When the reception of the restricted access programme has not been authorized a noise oscillator 63 is enabled and the signal of that programme is rendered unintelligible. When the reception of the programme is authorized the noise oscillator is rendered inoperative and reception proceeds normally. Authorization is provided by the transmitter sending a code signal which comprises four frequencies in the range 500 to 1200 kHz in overlapping time sequence and modulated on a carrier of 34 to 35À2 MHz. The carrier is amplified and detected in 32 and the modulation excites the appropriate ones of tuned circuits 154 to 160, if the respective frequencies are being transmitted. The resulting signals are detected and fed as inputs 1 to 4 to the logic circuits 60 and 62. If the appropriate overlapping sequence of frequencies corresponding to the receiver calling code has been transmitted an enabling signal is derived from the NAND gate 4 in the bottom right hand corner of logic circuit 60. The enabling signal is applied to the input NAND gates of logic circuit 62 which energizes outputs A and/or B according to a precise sequence of further switching of the tones, and according as to which ones of two not freely available signals it is authorized to receive. The outputs A and B are connected to the programme selector switch 50 to cause enabling or disabling of the noise generator 63 according as an unauthorized or an authorized programme is selected.

Abstract: 919,263. Adjusting radio tuning controls; automatic tuning arrangements. NURNBERGER SCHWACHSTROM - BAUELEMENTE FABRIK G.m.b.H. July 6, 1959, No. 23147/59. Class 40 (5). A motor-operated automatic tuning device for a television receiver is characterized in that the motor circuit includes a first two-position switch 1 operated by simultaneous reception of sound and vision signals; a second two-position switch 2 actuated by the motor shaft to reverse the direction of rotation when the tuning device has reached one of its limit positions, which is connected between a current source and the break contact a of the first switch; and a three-position switch 3 connected to the make contact b of the first switch 1 which is actuated from its neutral position to rotate the motor in one sense or the other dependent upon the frequency difference between a received vision signal and the frequency to which the receiver is tuned, and which reverts to neutral when frequency coincidence is established. In a first embodiment, Fig. 2, the motor M controlling a variable capacitor or variometer is energized from the source 4a over switches Sa, 1a and 2a. The end of the tuning range switch 2 is changed over by a contact on the motor from a to b, reversing the direction of the motor and switch 9 closes operating a wave change mechanism 11. On receipt of simultaneous sound and vision signals corresponding to a transmission, both windings relay 6 are energized to change over switch 1 to the fine tuning position. The output from the frequency discriminator in the vision channel is applied to a polarized relay 7 which provides fine tuning, a resistor 14 being included in the motor circuit to reduce its speed. The motor may be restarted by momentarily moving switch S to contact b. In a second embodiment, Fig. 4, the switch S is omitted and is replaced by four three-way switches 13, 13<SP>1</SP>, I, I<SP>1</SP>, III, III<SP>1</SP>, IV+V, (IV+V)<SP>1</SP>. Operation of switch III, III<SP>1</SP> for example will cause the motor to run until the device 11 switches the receiver to Band III, and then stop on the first signal in this band. Other transmissions in this band may be selected by momentarily closing the switch to contact b to restart the motor. Operation of switches I, I<SP>1</SP> or IV+V (IV+V)<SP>1</SP> will similarly select a station in Band I or Bands IV+V. In a modification of this embodiment (Fig. 3, not shown), switches 13<SP>1</SP>, I<SP>1</SP>, III<SP>1</SP> (IV+V)<SP>1</SP> are omitted, the band change circuit being that of Fig. 2. The control voltage for the relay 6 may alternatively be provided by mixing the sound and vision intermediate frequency signals in a diode mixer and obtaining the difference frequency (Fig. 5, not shown).

Abstract: 533,449. Road signals for controlling traffic. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and THOMPSON, G. W. Aug. 12, 1939, No. 23333. Drawings to Specification. [Class 118 (ii)] In a vehicle-actuated system for three or more lanes of traffic in which right of way is given to one lane at a time and is transferred to other lanes in the order of their demands, the continued demand from a lane from which right of way is forcibly removed becomes effective again at the instant when the next lane receives right of way, that is, at the end of the amber period. A system of the kind described in Specification 512,439 in which the camshaft controller occupies the same position for the corresponding signal in respect of each of the phases is modified to deal with demands on this " first-come, firstserved " basis rather than on a cyclic basis by the provision of a conversion unit comprising an additional relay for each phase. These relays are arranged so that only one can be operative at a time, and are controlled by the demand relays (AR &c.) to determine the next phase to receive right of way. Moreover the relay associated with a phase losing right of way by maximum timing, for example, cannot operate until the secondary phase relay (AS &c.) falls back at the end of the amber period, so that right of way cannot revert to that phase until all the demands made before that time have been met.

Abstract: 1299645 Explosive actuation of switches ELECTRICITE DE FRANCE 14 May 1970 [16 May 1969 19 Feb 1970] 23449/70 Heading H1N An electric switch has two contact members 31, 32 bridged by a rod-like member 33, which also acts as a plug for a passage 40, to prevent flow of arc-extinguishing pressurized fluid from reservoir 39, but on detonation of an explosive charge 43, the member 33 is displaced and the fluid is released to extinguish any arc produced. A piston 45, in cylinder 35, rests on top of an extension 45 of member 33 and also blocks a passage 41 between explosion chamber 46 and an expansion chamber 38. The member 33 is forced downwards by the explosion, disengaging from contact 31 and allowing the fluid, e.g. SF 6 , air or liquid, to pass from chamber 39 through passages 40, 42 into the expansion chamber 38, thus extinguishing any arc produced. Gases produced by the explosion pass from cavity 46 into the chamber 38 through passages 41 when the piston 45 has reached the end of its travel. In the arrangement in Fig. 1 (not shown) a part of the bridging member fractures on detonation of the charge. Several of the switches may be mounted on a rotatable disc or drum for successive or simultaneous operation.
