IPC: C01B3/48
Filed: 1989-01-12
Abstract: A process is described for converting carbon oxylsulfide and/or carbon disulfide, possibly in combination with hydrogen cyanide, O2 and/or SO2 in a reducing CO containing gas stream by the catalytic hydrolysis of COS and CS2, followed by the removal of H2S, present and formed, from the gas stream. According to the invention, the process is characterized by   a) a first stage (12) comprising converting a portion of the CO present with water in the presence of a catalyst with simultaneous or subsequent hydrogenation of any O2 and/or SO2 that may be present; b) a second stage (14) comprising catalytically hydrolysing COS and/or CS2, possibly in combination with HCN in the gas stream, with water; and c) a third stage (20) comprising removing substantially all sulfur components from the gas stream; the catalytic conversion of CO in stage a) being effected so that the heat thereby produced is substantially sufficient to raise the temperature of the gas stream to the value required for the hydrogenation and for the second stage.

Title: Improvements in or relating to code converters
Inventor: DAVIES DONALD WYNN
IPC: H03M7/12
Filed: 1959-01-06
Abstract: 894,986. Digital electric calculating-apparatus. STANDARD TELEPHONES & CABLES Ltd. Jan. 1, 1960 [Jan. 6, 1959], No. 493/59. Class 106 (1). A code converter converts a pure binary number into binary coded decimal or sterling by repeated addition and/or subtraction of a diminishing series of binary coded constants, the result of each addition or subtraction, according to whether it is positive or negative, causing a 1 or a 0 to be applied to the output. The number to be converted is entered into conversion register 2 in series mode. According to whether the sign is positive or negative in cell 3 detector 9 connects register 2 to subtractor 6 or adder 5. At the same time counter 22 actuates constants selector 26 to select the appropriate senior constant. On the decimal scale this is 8 x 10<SP>n</SP> and is selected in known manner from inspection of the contents of register 2. This constant is added to or subtracted from the original number and re-entered into register 2. According to whether the sign in cell 3 is now + or -, the detector 9 through register selector 10 enters 1 or 0 in the first place of register 11. The process repeats using as constants 4 x 10<SP>n</SP>, 2 x 10<SP>n</SP> and 1 x 10<SP>n</SP>, after which the next entries are made in register 12 in respect of the next decimal denomination. If as a result of the least step in respect of a denomination the number in the register 2 is negative, detector 9 inhibits counter 22 and the constant concerned is re-added to the number. The output registers 11-21 may control card punches. In respect of binary to sterling conversions a different set of constants is used and the series includes a few constants which are repeated.
