Title: Process for manufacturing a hydrogen and carbon monoxide-containing gas
IPC: C01B3/36
Filed: 1973-11-27
Abstract: 1491676 Reducing gas SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 25 Nov 1974 [27 Nov 1973] 54876/73 Heading C5E In a process for manufacturing a hydrogen- and carbon-monoxide-containing gas by partial combustion of a hydrocarbon fuel, the gas is cooled in a waste heat boiler and then washed to remove soot and acidic gaseous contaminants, the washing liquid being an aqueous solution containing at least 10% wt. of an alkaline watersoluble salt, and the fouled solution is subsequently regenerated by removal of absorbed gases and soot and recycled to the scrubber. The pressures in the combustion reactor, waste heat boiler and scrubber are preferably substantially the same, and the salt solution is regenerated at a lower pressure. The absorbed gases are removed by stripping with steam and the soot removed either by pelletizing with a binder such as naphtha or by taking up the soot particles into a hydrocarbon phase. A preferred method is a combination of these processes in which the agglomerates separated by pelletization are taken up in a hot fuel oil, the naphtha stripped off and returned to the pelletizer and the oil/soot mixture used as part of the fuel for the partial combustion. If the fuel used contains traces of metal compounds, the ash produced is taken up by the salt solution in the scrubber and converted to insoluble alkaline compounds during regeneration.

Abstract: 553,565. Ticket-issuing machines. AUTOMATIC ELECTRIC TOTALISATORS, Ltd. Sept. 8, 1941, No. 11481. Convention date, Sept. 6, 1940. [Class 106 (iii)] A ticket printing and issuing machine comprising paper feeding and severing means, a printing wheel adjustable under the control of a slidable selecting handle to bring a required printing face into printing position, is characterized in that the printing wheel is rotated by means of a drum around which is passed a cable attached to the selecting handle. The invention is applied to a machine issuing tickets in conjunction with totalisators. The race number is set on wheel 30 through escapement 31 actuated by the core 32a of solenoid 32 energized as required. Flats on shaft 33 are set for printing "WIN" or "PLACE" by moving slide 35 in one or other direction. Handle 27 is slid along rod 28 until opposite the required horse number, cable 23 rotating drum 24 and hence printing wheel 22 to position the corresponding type in the printing head. Handle 27 is then pressed inwards for its indicator 27a a to enter a serration in bar 29, the pairs of pins 56, 57 on the foot of the handle 27 being made to contact bars 53 and " horse " studs 54, so that according to the position of slide 35, a "WIN" or a "PLACE" circuit is prepared to receive an impulse and register the bet at a central station. This impulse energizes relay 51, Figs. 3 and 8 (not shown) to unlatch stud 45 which then contacts stud 44, Fig. 4, and closes the circuit to motor 9 while opening cut-out 52, Relay 51 is thereby de-energized. The motor drives shaft 7 through belt 8. Cams 14 release frame 11 which descends under spring action to press platen 10 against the paper strip 1, ink ribbon 17 and printing head. Cams 14 then raise the platen through frame 11 which operates the ink-ribbon escapement 20, Fig. 3 (not shown). At the same time, cam 42 raises arm 39, Figs. 4 and 5, to depress guillotine blade 37, while the roughened portions 4a of roller 4 contact the strip 1 to feed it through the outlet 6, after which cam 42 releases arm 39 to allow blade 37 to sever the strip under spring-action. Before the completion of the cycle, cam 48 moves studs 44, 45 to relatch stud 45, after which stud 44 returns to break the circuit. Handle 27 is kicked out of the serration on bar 29 by a bar 59, Fig. 6, reciprocated and lifted by an eccentric 60 (not shown) on shaft 7, so that the bridge between parts 53 and 54 is broken. Continued inward pressure on handle 27 causes the issue of a number of like tickets the number being indicated by the number of outward kicks on the handle. A mechanical counter 65, Fig. 4, can be provided to count the revolutions of shaft 7 and hence the number of tickets issued.

Abstract: 1410367 Automatic exchange systems; transistor switching circuit WESTERN ELECTRIC CO Inc 20 Dec 1972 [20 Dec 1971] 58743/72 Headings H4K and H3T A call holding circuit, for permitting keytelephone subscribers to effect interim calls, comprises a transistor circuit which is connectable as a looping impedance across the line under the control of a photo-resistive arrangement. As shown, depression of a subscribers holding key closes contacts 5, 6 thereby enabling a bi-stable 16 to turn-on transistor 47 and thus illuminate lamp 48. An SCR 18 and a transistor 19 are turned-on due to the change in bias voltage provided by photoresistor 39, so as to provide a low impedance path incorporating a lamp 59 across the line wires 13, 14. Diode bridge 20 merely protects against line polarity reversals. If the distant party releases, central office battery is temporarily disconnected from the loop, whereby lamp 50 dims and photo resistor 54 increases its impedance so as to bias-off transistor 23. After a delay produced by the charging of capacitor 25 and provided so as to guard against transients, e.g. lighting surges, a Darlington pair 24 is enabled to activate a monopulser 27 and so reset the flip-flop 16. As a consequence the SCR 18 which was turned-off by the loop disconnect pulse, is maintained disabled, thus removing the hold condition. The latter effect is also obtained by the local subscriber reseizing his line by operation of his key contact 4 in which case the darkening of lamp 48 precedes the disablement of the SCR. A Zener diode 21 fixes the base/emitter voltage of transistor 19 thus causing this transistor to act as a constant current source irrespective of the length of the line.
