Abstract: 1,222,199. Separating components of gaseous mixtures by absorption. METALLGESELLSCHAFT A.G. 29 Sept., 1969 [5 Oct., 1968], No. 47844/69. Heading B1L. A gas mixture to be separated passes under pressure by line 1 to dryer zone 2 where water vapour is absorbed by rich solvent which enters by line 3. The virtually dry gas then rises through absorption zone 4 in counterflow to lean solvent which enters by line 12, and which absorbs the desired component of the gas mixture rich solvent bottoms passing partly to zone 2 and partly to flash vessel 15, gases released therein being returned by lines 17, 19 to absorption zone 4. Effluent gases laden with absorbent vapour from zone 4 pass to and through zone 5 in counterflow to water which enters by line 6, and leaves laden with solvent by line 7; the unabsorbed gas fraction leaves by line 8. Solvent from flash vessel 15 is flashed again in vessel 23, and then passed by line 25 to the head of regeneration zone 26 where it is flashed yet again, in counterflow with stripping gas which enters by line 27; this gas is, first dried by contact with dry solvent which enters zone 28 by line 29 before passing to zone 26. Solvent laden water from zone 5 passes by line 7 to and through afterscrubber 36 is counterflow to water entering by line 37; stripping gas from which all solvent has been removed leaves by line 38. Solventladen water passes variously to distillation column 34 by lines 39 and 31, 50 and 33. Gas from flash vessel 23 passes to the column 34 by lines 51, 42, a side stream passing thereto by line 40, reboiler 41 and line 43. Water enters column 34 by line 52 and excess gas leaves by line 49. Regenerated solvent leaves by lines 47, 48 back to flash vessel 23, and thence, via zone 26 and lines 11, 12 to absorption zone 4. In the Example, a gas stream consisting principally of 33.2% (vol.) CO 2  and 64.5% (vol.) H 2 , but also containing small amounts of CO, CH 4 , N 2  and A is treated in the process with N-methyl pyrrolidone as absorbent for the CO 2 , yielding a product consisting of 96.5% (vol.) H, and only 0.1% (vol.) CO 2 .

In a substation circuit, a resistance Wil is connected in series with the impulsing contacts nsi of the dial, and both are shunted by the normal dial contact nsr. In consequence the initial line current Is is reduced to a value Iw during each pulse train and restored at the end thereof. At the exchange, relay C responds to a calling condition, and square pulses arising from the reduced line current pass through a transformer KVIII and transistor TV to energize relay V and so operate relay H. Break pulses energize relay A through transformer KAIII and transistor TA. At the end of the pulse train, the restoration of the orginal line current releases both V and A.

An apparatus for storing foodstuffs, such as hay silage or undried grain, requiring protection from oxygen in the air over a substantial period of time during which time it is withdrawn at intervals, comprises a rigid outer supporting structure 10 and an inner flexible air-impervious container 16. The structure 10 may comprise a cylindrical framework of metal tubes 11 carrying metal sheeting 13 and wire mesh 15 as shown, or may comprise a metal-band-reinforced timber shell, or may be constructed of concrete.

Abstract: 1411569 Rectifying SONY CORP 30 Oct 1972 [5 Nov 1971] 49972/72 Heading H2F A rectifying arrangement comprises a series circuit of capacitor 2, diode 3 and capacitor 4 connected in that order across A.C. supply terminals 1a, 1b with D.C. output terminals across capacitor 4. A switching device, such as transistor 9 is connected across the series circuit of capacitor 2 and diode 3 and is controllable by a signal at 14 inhibited, e.g. by transistor 13 when a high value of A.C. supply voltage is received, so as to change the rectifying operation. The D.C. output is thus substantially the same from 110 and 220 V A.C. inputs. As described, on 110 V input, sine or square wave signals at 14, in phase with the A.C. supply at 1a, 1b, are amplified by transistor 15 and turn on transistor 9 on positive half cycles only, giving half wave rectification. On 220 V input, the voltage across capacitor 12 is sufficient to turn on transistor 13 which inhibits the signals at 14. During positive half cycles, capacitors 2 and 4 are charged in series via diodes 3 and 5, whilst during negative half cycles, transistor 9 is turned on, discharging capacitor 2 into capacitor 4 giving about half the supply voltage across capacitor 4. High frequency signals, e.g. TV line pulses, may be employed at 14 to minimize the size of transformer 16: the output voltage may be controlled by variation of the high frequency. In Fig. 5 (not shown) two circuits of the form shown in Fig. 1 are combined to provide a system giving the same D.C. output from 110, 220 or 330 V. The systems are applicable to power supply for TV, radio or tape recorders.
