Title: Colour synchronising system for a colour television reciever
IPC: H04N11/16
Filed: 1971-10-07
Abstract: 1360445 Colour television GENERAL CORP 7 Oct 1971 [9 June 1971] 46628/71 Heading H4F  The reference signal for demodulating the B-Y component of a PAL colour television signal is produced by frequency dividing by two a signal at twice the subcarrier frequency derived from one of the sidebands of the swing- ing burst synchronizing signal. The sideband may be separated using a burst gate 1 and a filter 2, (or an oscillator synchronized with the sideband), and the sideband is passed to a phase modulator 3 where it is phase modulated by a sawtooth waveform of period equal to the line period. The resulting signal is passed to the R-Y demodulator 5 and to a frequency multiplier 9 comprising a pair of diodes and an output circuit tuned to double the subcarrier frequency. The signal from multiplier 9 is passed to a counter circuit 10 having a resonant circuit tuned to the colour subcarrier frequency whose output is passed to B-Y demodulator 11. Ambiguity in the phase of the output of circuit 10 is resolved by using a gate 8 gated on by a signal from a relaxation generator 7 controlled to operate at half line frequency by the output of a phase detector 6. In an alternative embodiment (Fig. 8, not shown), multiplier 9 is dispensed with, circuit 10 instead receiving its input from a detector (15) which frequency adds the signals from filter 2 and from a further filter (14) tuned to separate a sideband of the burst signal spaced from the subcarrier frequency by an equal and opposite amount to the sideband separated by filter 2. An automatic phase control circuit may be provided to control the operation of an oscillator substituted for filter 2 (Fig. 9, not shown).

Abstract: 1359058 Disazo solvent dyes FARBWERKE HOECHST AG 8 Oct 1971 [10 Oct 1970] 46887/71 Heading C4P The invention comprises disazo solvent dyes having the general formula  where R 1  is H or C 1-4  alkyl or alkenyl; and R 2  and R 3  independently represent an alkyl or alkenyl group, with the proviso that the total number of carbon atoms in said groups is from 3-20, or R 2  and R 3  together with the quaternary carbon atoms form a cycloalkyl or cycloalkenyl ring. The dyes may be obtained by coupling a diazotized aniline with α-naphthylamine, diazotizing the resulting monoazo dye and coupling it with an appropriate 2,3-dihydroperimidine. The dyes give red and violet shades in oils, fats, waxes, plastics, material and synthetic resins, textile materials and paper.

Abstract: 1,219,559. Closed circuit gas turbine plant. SULZER BROS. Ltd. Sept. 24, 1969 [Oct. 1, 1968], No. 46982/69. Heading F1G. [Also in Division G6] In a method of operating a closed circuit gas turbine plant, a portion of the working fluid is branched off from the gas circuit, is condensed and then returned to the gas circuit without any appreciable pressure change. The plant shown uses CO 2  as the working fluid and the heat source 13 may be a nuclear reactor. Working fluid enters the compressor 1 at inlet 2 and is compressed therein. A portion, such as one-half of the working fluid is taken off at point 4 where the pressure is 73 ata and temperature 80‹ C., this portion being passed to a condenser 5 where it is condensed for example by water, the conditions at point 6 being 70 ata and 28‹ C. The condensed fluid is then supplied by pump 7 back into the compressor at point 8, the conditions being 80 ata and 33‹ C., where it re-combines with the gaseous portion. The mixture is further compressed, the conditions at the outlet 10 being 250 ata and 127‹C. The fluid is then pre-heated in heat exchanger 11 by turbine exhaust fluid, the conditions at the heat exchanger outlet 12 being 240 ata and 282‹ C. The working fluid is then heated in the reactor 12 the conditions at the outlet being 230 ata and 560‹ C. at which it enters the turbine 15. After expansion in the turbine the working fluid is 43 ata and 370‹ C and after passing through the heat exchanger 11 the conditions are 41 ata and 140‹ C. The working fluid then passes to pre-cooler 19 where it is cooled before returning to the inlet 2 of the compressor at 40 ata and 80‹ C. The turbine drives the compressor also a useful load in the form of a generator 3. The plant has a power of 30 MW and the rate of flow of working fluid is 3 metric tons per second. In Fig. 3 in place of the pump 7, an ejector 21 is utilized to return the condensed fluid to the compressor which is in two parts 1a, 1b, the fraction of working fluid which does not pass to the condenser 5 being utilized as the motive fluid of the ejector, the proportions being variable by means of valves 23, 25.

Title: Method of increasing the chain length of aldehydes
Inventor: FREYSCHLAG HERWIG
IPC: C07C45/72
Filed: 1964-11-27
Abstract: Polyunsaturated aldehydes are produced by reacting an aldehyde with an ylenal of formula <FORM:1079217/C2/1> in which Ar is an aryl radical which may be substituted by alkyl or alkoxy groups; R1, R2 and R3 are hydrogen or alkyl groups, and n is an integer from 1 to 6. The reaction takes place according to the following equation <FORM:1079217/C2/2> <FORM:1079217/C2/3> in which R4 may be a saturated or unsaturated alkyl, cycloalkyl, aryl or aralkyl radical. The radical R4 may contain, for example, the group <FORM:1079217/C2/4> Dialdehydes may also be used as starting materials and in that case two molecules of ylenal are reacted with one molecule of dialdehyde. Examples of suitable starting aldehydes are b -ionylidene acetaldehyde, b -retinene, a -retinene, b -apo-141-carotinal, b -apo-81-carotinal, b -apo-121-carotinal, b -apo-101-carotinal, b -apo-61-carotinal and the aldehydes OHC-C(CH3) = CH-CH = CH-CH = C(CH3)-CHO, OHC-CH = CH-C(CH3) = CH-CH = CH-CH = C(CH3)-CH = CH-CHO and OHC-C(CH3) = CH-CH = CH-C(CH3) = CH-CH = CH-CH = C(CH3)-CH = CH-CH-C(CH3) CHO.  Suitable ylenals are for example those in which the aryl groups are all phenyl groups. The aldehydes obtained can be further reacted with an ylenal to get a longer-chained aldehyde. In the examples (a) Vitamin A aldehyde is reacted with triphenyl phosphine-2-formylpropen-1-yl-methylene to give b -apo-121-carotinal; (b) b -apo-121-carotinal is reacted with triphenylphosphine - 2 - formylpropen - 1 - yl-methylene to give b -apo-81-carotinal; (c) triphenyl formyl buten-2-yl-1-phosphonium chloride is reacted with triphenylphosphine-2-formylpropen-1-yl-methylene and the product is reacted with Vitamin A aldehyde to give b -apo-81-carotinal; and (d) triphenyl-3-formylbuten-2-yl-1-phosphonium chloride is reacted with triphenylphosphine - 2 - formylpropen - 1 - yl methylene to give triphenyl phosphine-2,6-dimethyl - 6 - formylhexatriene - 1,3,5 - yl-methylene which is reacted with triphenyl-3-formyl-butene-2-yl-1-phosphonium chloride to give triphenylphosphine - 2,6,10 - trimethyl-10 - formyl decapentaene - 1,3,5,7,9 - yl-methylene.
