Title: Method for synchronizing color television signals
IPC: H04N9/44
Filed: 1965-10-12
Abstract: 1,119,358. Colour television. GENERAL CORP. 12 Oct., 1965 [13 Oct., 1964], No. 43202/65. Heading H4F. In a line-sequential colour television system employing odd-line interlaced scanning the sequence of the three primary colour signals at a transmitter and at a receiver is synchronized by detecting the leading edge of a vertical synchronizing pulse in an odd-line field, or an evenline field, and thereby causing the first scanning line of each frame to correspond to one of the three primary colours. The Specification describes in detail a converter unit adapted to translate an NTSC-type signal into a linesequential colour image signal with the sequence of red, green and blue, having the red colour component indexed for the first scanning line of the odd-line field by the vertical synchronizing pulse of the odd-line field. This linesequential signal may then be transmitted, or magnetically recorded, and reproduced at a line-sequential type television receiver wherein the vertical synchronizing pulse is detected, thereby obtaining the desired colour image with its colour components correctly synchronized. The above synchronization of the sequence of the three primary colour signals is effected by producing an " odd-number pulse " from the leading edge of an odd-line vertical synchronizing pulse, and supplying it to a ring counter circuit which in the converter unit produces the gate pulses which open in sequence the three gates to which the three primary colour components signals produced from the input NTSC type signal are applied, Fig. 4 (not shown), and which in the line-sequential type television receiver produces the pulses which are fed to a stepped-waveform generator, the output of which is applied to the control grid structure of a single electron gun type picture tube, Fig. 11 (not shown). The " odd-number pulse " is produced from the television synchronizing signals, which have been separated from the composite video signal, by a Hartley type blocking oscillator 15, Fig. 5, a one-shot multivibrator 16, an integration circuit 17, e.g. a Miller integrator, and an AND-gate circuit 18. The waveform of the oscillator output, Fig. 6, b-b<SP>1</SP>, which is used to trigger the ring counter circuit, is applied to the multivibrator which develops the pulses as shown in Fig. 6, c-c<SP>1</SP>. The output of the integration circuit 17 comprises negative vertical synchronizing pulses as shown in Fig. 6, d-d<SP>1</SP> with its leading edge delayed for about 6 microseconds. In AND-gate circuit 18 diode 115 has the pulses as shown in Fig. 6, c-c<SP>1</SP> applied thereto, and diode 114 has the vertical synchronizing pulses Fig. 6, d-d<SP>1</SP> after they have been differentiated by means of capacitor 112 and resistor 113 as shown in Fig. 6, e-e<SP>1</SP>, applied thereto. The resultant output from the AND-gate comprises a negative " odd-number pulse " which is shaped by transistor pulse amplifier 117 and tuned into a positive " odd-number pulse " such as shown in Fig. 6, f-f<SP>1</SP>.

Abstract: 1375328 Combined reaction crystallizer and classifier CHIYODA CHEMICAL ENG & CONSTRUCTION CO Ltd 19 Sept 1972 [23 Sept 1971] 43368/72 Heading B1G A combined reaction crystallizer and classifier 1, comprises a suspension zone 2, 2a, 3 and 3a, and a classifier zone 4 including a recovery zone 4a. The suspension zone contains an outer chamber 7 which receives a crystal slurry from reaction zone 9, via circulation chamber 6. In the outer chamber the slurry is separated by density difference into a dense slurry 19 and a clear liquid and the latter by pipe 17 is passed to classifier 4. The reaction is effected between reactant A fed by pipe 11 into zone 9 and reactant B supplied to zone 9 by pipe 12. An air supply 13, directs reactant B into the reaction zone. The supply 13 may be separate from or admixed with B. In the classifier zone, an air supply 18 positioned above the pipe entrance 17, maintains circulation of the slurry and accumulates seed crystals in zone 9. When the crystals have grown to a grain size sufficiently large to overcome the upward flow of the current they fall, pass through barrel 3, and are withdrawn from passage 5. The crystallizer may be used for producing gypsum by reaction of an aqueous solution of sulphuric acid with limestone.

Abstract: 1,170,360. Segregation of ores. ANGLO AMERICAN CORP. OF SOUTH AFRICA Ltd. Sept.25, 1967 [Sept.28, 1966], No.43447/67. Heading C7D. A segregation process for the treatment of ores in which the ores are heated in a fluidized bed and then flow as a plug through the segregation chamber where the segregating reagents are added, is improved by causing the level of solids in the chamber to oscillate between predetermined levels. The level is varied by controlling the discharge from the bottom of the chamber. The discharge may be fed to a quench tank and the segregated metal recovered (e.g. by flotation). It is stated that a 70-80% conversion of copper minerals to copper can be achieved.

The protective circuit 14 may be the protective arrangement of Specification 1,207,839 and the filter circuit 24 is similar to that disclosed in Specification 1,207,839. The output signal from the filter circuit 24 is applied to an amplifier 26 and through an emitter follower 28 to signal detectors 30, 32 which respond rapidly to positive and negative portions of the signal from the emitter-follower 28.

Filed: 1965-10-26
Abstract: A polyester resin composition comprises in admixture an uncured unsaturated polymeric phthalate ester comprising a tetrabromophthalate ester such that the phthalate ester contains less than that weight percentage of bromine which would be sufficient to make the polymeric phthalate ester self-extinguishing alone, and antimony oxide in less than the weight percentage which would be necessary to make the same polymeric phthalate ester self-extinguishing without the bromine, the composition being self-extinguishing.  The composition may also comprise a vinyl or vinylidene monomer as a cross-linking agent and a gelation inhibitor to prevent cross-linking.  A gelation initiator may be added to cross-link the polyester.  In examples, polyesters are prepared from tetrabromophthalic anhydride, phthalic anhydride, maleic anhydride and propylene glycol.  Hydroquinone and styrene are also used.  In Example 2, sodium chloride is used.  The compositions are cured-glass fibre laminates, using t-butyl hydroperoxide.  In a comparative example, chlorendic anhydride is used instead of tetrabromophthalic anhydride.

The discharge device 38 comprises a series of scrapers 72 on an endless belt arranged transversely of the hearth, and this is separated from the delivery pipe 46 by the baffle 27 which extends very close to the hearth acting as a partial seal to prevent the escape of hot gases. A dependant roof 66 in the chamber 28 assists the further preheating of freshly charged limestone by forcing the effluent gases into contact therewith.  The hearth is driven by a motor and a pinion, Fig. 5 (not shown), engaging a rack 57, Fig. 1, on the underside of said hearth.
