Abstract: Acetylene is recovered from thermal or electrical cracking processes (with or without oxygen) by washing with an acetylene solvent in a preliminary stage to obtain a preliminary wash liquor and a gas which is washed with a larger amount of solvent under pressure to obtain a main wash liquor, expelling acetylene from the main wash liquor and purifying the acetylene by countercurrent contact with the main wash liquor, removing from the main wash liquor a mixture of compounds more soluble than acetylene by means of steam and/or solvent vapour and contacting the resultant mixture with the preliminary wash liquor. Solvents mentioned are aqueous butyrolactone and N-methylpyrrolidone. Gas in line 1 is washed in tower 2 with solvent from line 3 and the gas in line 4 is compressed and washed in main wash tower 6 with solvent from line 7. Liquor in line 9 is passed through stripper 10 and then into degassing tower 12. Released gases pass into the base of stripper 10. Some acetylene leaves by line 14 and is recycled to tower 6 and pure acetylene is recovered by line 15. More soluble gases with water and solvent vapour are obtained from tower 12 by line 16 and enter the base of column 17 to the top of which is passed preliminary wash liquor in line 29. Gases in line 18 are water washed in tower 19 to recover solvent which is returned by line 22 to tower 12. Stripped solvent from column 17 is partly returned to tower 2 and partly fractionated in column 25 to recover solvent in line 27, polymers being removed by line 28.

Abstract: The invention has particular utility in connection with combustion control systems that employ lead sulfide (infrared sensitive) photoconductors in conjunction with band pass amplifiers. Flame relays in such systems would occasionally hold in after flame failure due to continued generation by the photoconductor of fluctuating signals. A flame failure transition responsive circuit is connected in series between the photoconductor and the flame relay and responds to an abrupt decrease in the flame signal to insure dropout of the flame relay.

Abstract: 1355376 Time delay switching circuits ELECTRONICS CORP OF AMERICA 20 July 1971 [3 Aug 1970] 34021/71 Heading H3T [Also in Division F4] Combustion of a burner is initiated by closing contacts 60-2 of a switch 60 to connect a capacitor 62, previously charged through contacts 60-1, to the base of a transistor 72 which actuates a transistor 46 to open a fuel valve 50, thus allowing an ignition attempt. The period allowed for ignition is determined by the discharging of capacitor 62 which switches off transistor 72 to close valve 50 unless successful ignition holds the valve open by means of an ultra violet sensor 20 which switches on a transistor 36 through a transformer 26 when a flame is present, and thus keeps transistor 46 in its conducting state.

Abstract: Scanning apparatus includes a linear array of sensors so that there is effectively a series of independent sensor elements disposed in aligned relation generally perpendicular to a scanning axis. Each sensor is arranged to provide a data output in response to a sensed code mark and an output channel is coupled to each sensor. Logic responsive to detection of a first code mark by a sensor of the array enables at least one code sensitive group of output channels and disables other output channels so that only a limited group of channels are rendered responsive to subsequently detected code marks.

Abstract: A code sensing system includes scanning means for producing electrical signals corresponding to code marks in a row. The value of the code mark is determined by its position in its digit space in the row. A code sampling gate is generated at a particular point in each digit space and a data output is produced if the scanning means is producing a code mark output at that time.
