Abstract: 1380960 Sulphur; desulphurization of waste gas AMOCO PRODUCTION CO 27 April 1972 [21 June 1971] 19687/72 Heading C1A A gaseous stream containing hydrogen sulphide is desulphurized by subjection to an oxidation step to produce a reaction mixture in which the hydrogen sulphide and sulphur dioxide are present in a molar ratio of about 2 : 1, a portion of the reaction mixture being passed through a first catalyst bed having sulphur deposited thereon, the reaction mixture being maintained within the bed at a temperature above the sulphur dew point whereby sulphur in the catalyst is removed in the form of a vapour containing in addition unreacted hydrogen sulphide and sulphur dioxide, separating sulphur from the vapour, introducing the resulting sulphur-denuded vapour into a second catalyst bed to form additional sulphur at a temperature above the sulphur dew point, withdrawing reaction products from the second bed and removing sulphur therefrom to obtain a sulphur-denuded stream, and thereafter passing the last-mentioned stream into a third catalyst bed at a temperature below the dew point of sulphur thus depositing sulphur on the catalyst in the third bed. The temperature in the second bed is maintained at 600‹ F. or above when an excess of COS and CS 2  of 0À1% is present in the reaction mixture. The path of the reaction mixture may be switched to the second bed after the sulphur in the first bed has been completely removed and the subsequent stream from the second bed is passed to the first and third beds in succession. The temperature of the stream introduced into the first bed for sulphur removal therefrom may be from 450-700‹ F and the inlet temperature of the vapour introduced into the second bed may be between 300‹ and 550‹ F.

Title: Improvements in apparatus for effecting repeated closings of automatic electric switches
IPC: H02H3/07
Filed: 1922-07-20
Abstract: 186,036. Akt.-Ges. Brown, Boveri, et Cie. Sept. 10, 1921, [Convention date]. Cut-out arrangements.-A circuit breaker opening on overload is re-closed automatically by am arrangement of relays for a predetermined number of times if the overload persists after which it finally remains open. Current is supplied to a network c through an overload circuit breaker b from supply busbars a while the latter are under voltage, a transformer h energizing a relay d to bridge its contacts. If the switch b is tripped on overload contacts k, i are bridged and a circuit completed from the transformer through the contacts of relay d and time-delayed relays f, g in parallel. The relay f after a comparatively short interval (e.g. 10 sees.) completes the circuit of the closing coil m and immediately returns to its initial position. The relay g having a larger time delay (e.g. 35 sees.) moves slowly back towards its initial position having passed through only a portion of its motion. If the overload persists, the circuit breaker b again trips and a similar re-closing action ensues, the time delay of the relay g being reduced each time by approximately the same interval (e.g. 10 sees.) so that after a predetermined number of re-closures (e.g. 3) before a further closure can take place the relay g operates the switch n to open the circuit of the transformer h, the switch n being retained open by a latch o. If the overload on the network c is of shorter duration than the time taken for the above sequence of operations the circuit breaker b remains closed after one of its automatic re-closures, the relay g returning slowly to its initial position.

Each module also includes a decimal point which can be independently illuminated. The decimal points 40 form a colon dividing the hours numerals from the minutes, and the point associated with module 35 indicates P.M. if time is being displayed in a twelve hour mode. A twenty four hour mode can also be selected. Other displays which may be selected are seconds, alone, and day and month numbers. In the latter case, the points associated with modules 35 and 38 give a binary indication of the year in a four year cycle. The electronic package, Figs. 9-20 (not shown) includes a quartz crystal oscillator supplying pulses to dividers and counters using integrated circuit logic elements. Devices are included to provide automatic resetting of the date numerals at the end of each month, taking into account 30-day months and leap years. Setting arrangements are provided enabling the watch to be synchronized with a whole minute signal by holding the seconds count at zero, and allowing the hours count to be changed with- . out stopping the days count, so that corrections for different time zones may be made. Filters are provided to prevent the receipt of multiple pulses from contract bounce during manual setting. The power supplied to the display is automatically reduced if the ambient light or the supply voltage falls, and the readout is covered with a red filter and circularly polarising material to maximize contrast.
