Patent GB-659712-A (GB)
Title: Synthesis of oxygenated organic compounds
IPC: C07C27/22
Filed: 1949-10-21
Abstract: In the Oxo synthesis of aldehydes and alcohols, the liquid oxygenated product is treated to decompose the dissolved metal carbonyl, and the deposited metal is recovered by contact in the treating zone with a gas rich in carbon monoxide, and a liquid organic solvent for the metol carbonyl, boiling not substantially above 210 DEG  F., under conditions to yield a solution of metal carbonyl which, after adjusting its concentration, may be returned to the synthesis zone. The gas rich in CO is preferably synthesis gas.  Liquid butane or pentane or similar saturated hydrocarbons may be used as solvents which are removable from the carbonyl by simple flashing.  Part of the liquid olefin feed may, alternatively, be used.  Other solvents are ether, methanol, acetone, and halogenated hydrocarbons. Conditions for formation and removal of cobalt carbonyl in the decobalter are suitably 200-350 DEG  F., CO partial pressures of 1000-1500 p.s.i., and solvent feed rates of 0.5-5 vols./vol. decobalter space/hr.  Two decobalters are preferably used alternately for metal deposition and carbonyl formation.  Olefins of 6-8 carbon atoms, and CO, H2 mixture pass through a reactor which is preferably packed with crinkled wire screen or wire screen Berl saddles and fed with catalyst in the form of a solution of cobalt carbonyl in liquid butane.  Reaction products are cooled, gas separated, and supplied to a decobalter, which may be at a lower pressure and about 250-400 DEG F., to which hydrogen is fed, cobalt being deposited. The effluent is treated to separate liquid products which may be hydrogenated, and gases which may be recycled to the reactor or, after CO removal, to the decobalter.  When required, synthesis gas and liquid butane instead of hydrogen are fed to the decobalter, the effluent being freed of gas, at least part of the butane flashed off, and the carbonyl solution fed to the reactor.  If all the butane is flashed off, the carbonyl is taken up in liquid olefin feed.

Abstract: 1378292 Colour television; multiplex radio signalling MARCONI CO Ltd 19 April 1972 [12 June 1971] 27652/71 Headings H4F and H4L Simultaneous transmission of two signals U and V, e.g. the two chrominance signals in a colour television system or stereo radio signals, is effected by frequency modulating an oscillator output with instantaneous values of the expression arc tan V/U, and then amplitude modulating the frequency modulated output with instantaneous values of the expression #U<SP>2</SP> + V<SP>2</SP>. As shown in Fig. 1 the two signals U and V are fed to two balanced modulators 3 and 4 supplied with signals from a constant frequency oscillator 5 with 90 degree phase shift between them. The outputs U sin wt. and V cos wt. are combined at junction 14 to give #U<SP>2</SP> + V<SP>2</SP> sin (w + k#)t, where k is the modulator constant and # = arc tan V/U. Limiter 7 removes the amplitude term #U<SP>2</SP> + V<SP>2</SP> and discriminator 9 provides an output the magnitude and polarity of which is representative of the divergence of the applied frequency (w+k#) from the frequency w. The output of discriminator 9 is integrated 10 and applied to a VCO 11 to frequency modulate its output. The output from oscillator 11 has the form sin (w s +k#)t where w s  is the centre frequency, and this output is then amplitude modulated 12 by #U<SP>2</SP>+V<SP>2</SP> which is passed by envelope detector 13. A decoder for this signal comprises, Fig. 3, two synchronous demodulators 33 and 34 to which the amplified 31 encoded signal #U<SP>2</SP>+V<SP>2</SP> sin (w s +k#)t is applied. The two demodulators are also supplied with signals having a 90 degree phase difference (phase shifter 36) which are derived from the. amplified encoded signal after it has been amplitude limited 32 and delayed 35. The two signals U and V are derived from the two demodulators 33 and 34 via low pass filters 37 and 38. It is arranged that the delay period # of delay 35 is such that k#=1, and w s  is chosen to be equal to 2#nk where n is an integer. The amplifier 31 preferably included an AGC cicuit which is operated during the flyback periods of the television signal.
