Title: Method for reducing sulphur dioxide
IPC: B01D53/74
Filed: 1970-12-02
Abstract: 1328703 Reduction of SO 2  ALLIED CHEMICAL CORP 2 Dec 1970 [9 Dec 1969] 57279/70 Heading C1A Sulphur dioxide is reduced by (i) heating a gaseous mixture comprising SO 2  and a reducing agent to 1000-2400‹ F. by contact with a mass of hot solid, (ii) reacting the SO 2  and reducing agent on a catalyst to give a mixture of H 2 S, SO 2 , and S, and (iii) cooling the gaseous product to 700‹ to 800‹ F. by contacting with a mass of cold solid, the two masses of solid being used alternately in steps (i) and (iii). In the system shown in the drawing SO 2 -containing gas 2 is mixed with reducing gas 4 and most of this gas mixture is passed via valve 14 to chamber 18 where it is heated by contact with a mass of hot solid. The hot mixture then passes on via valve 24 and line 22 and is mixed in line 26 with the colder gas mixture, which had been taken off via lines 8 and 9 and valve 12, in order to achieve the desired temperature control. The gas mixture then passes through catalytic reactor 28 and the flow is again divided, a smaller proportion passing via lines 40 and 43 and valve 42 to line 44 where it is mixed with the larger part of the reactor exit gases which have been cooled by contact with a mass of cold solid in chamber 36. This gaseous mixture which contains H 2 S, SO 2  and S vapour then passes through sulphur condenser 46 and on to Claus kiln 50 for further reaction of H 2 S and SO 2  to produce additional sulphur. When the solid in chambers 18 and 36 have cooled and heated respectively to an optimum point the flow of gas through them is reversed using valve 14 so that the inlet gas mixture passes through lines 6, 10, 38, chamber 36, 35, 54, 57 and 26 and then into the reaction chamber 28, which it leaves via lines 30, 58, valve 60, lines 19, 16, 45 and 44 via chamber 18, sulphur condenser 46 and Claus kiln 50. This reversal of flow is repeated at preset time intervals to maintain the desired reaction conditions. The conditions under which the reaction is carried out are disclosed fully and the reaction is claimed in Specification 1,328,704.

In the embodiment shown, the reabsorption chamber 38 is defined by a resilient diaphragm 39 on the operating button 31 of a piston rod 18. Depression of button 31 reduces the volume of chamber 38 and effects the discharge stroke of piston 17, liquid being discharged from chamber 19 via passage 27, valves 28 and 35 and outlet 32 until the piston skirt enters recess 20, whereupon the pressure in chamber 19 is released via apertures 41 and valve 28 closes. On release of button 31, the resilience of diaphragm 39 restores it to its position shown, and liquid is sucked back from outlet 32 via valve 35 and aperture 30 into chamber 38. Valve 35 comprises a resilient plate with slits defining flaps which can open in either direction. Container 12 is vented during dispensing by ports 41, and a clearance between piston rod 18 and sleeve 16 which is closed by the piston 17 in its position shown. In Fig. 4 (not shown), diaphragm 39 is replaced by a spring- loaded piston (45) which also functions as the outlet valve, the discharge pressure moving the piston to its open position against a spring, which returns the piston to close the discharge passage and suck back liquid from the outlet at the end of the discharge stroke.

Filed: 1973-12-31
Abstract: 1435910 Signal detector circuits COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 31 Dec 1973 [29 Dec 1972] 60250/73 Heading H3T In a detector for alternating current signals comprising a first rectifier D2 connected to receive the A.C. input signal E1, E2 and a first capacitance C2 charged by the rectifier and shunted by first and second resistances B1 R2 in series, the second resistance R2 is shunted by a second capacitor C3, of larger capacitance than C2, in series with a second rectifier D3 output terminals S1 S2 are connected across the second resistance R2. The forward conduction direction of the second rectifier D3 is such that the second capacitor C3 charges with a predetermined time constant and smooths the output of the first rectifier D2 when an A.C. signal appears at the input of the detector and the second rectifier D3 isolates the charge on the second capacitor C3 the output terminals S1 S2 when the A.C. input signal disappears. The output S1, S2 may be used connected to an input of a threshold amplifier. When a data signal occurs at input E1, E2 a diode D3 conducts and the output voltage at. S1, S2 varies slowly due to the large time constant provided by the capacitor C3 having the larger capacitance than C2. When the data signal at E1, E2 ends the diode D3 turns off and the output voltage at S1, S2 rapidly falls due to the shorter time constant provided by C2, R1 and R2. The capacitor C3 discharges into R3 and the discharge is practically ended before the next input data signal occurs. A rapid discharge circuit L can be provided which includes a unijunction transistor T3 operating to ensure rapid discharge of the capacitor C3 when the data input at E1, E2 ends. The full-wave detector shown may be used in a transmitter-receiver with a twophase coded signal. The time constant on triggering are widely variable as a function of the amplitude of the incident signal and in order to overcome this a peak limiter (B, Fig. 3, not not shown) can be connected between the input E1 and a capacitor C1 and a Zener diode (Z) is also provided to stabilize the time constant on triggering. The Zener diode (Z) is connected between (A) the interconnection of diode D2 and the capacitor C2 and a taping (P) of the output resistor (R<SP>1</SP>2) so that input voltages of greater amplitude than the Zener voltage are applied (P) so that the voltage at output 51 is composed of a voltage proportional to this voltage rise at (A) and a fraction of the exponential voltage at the auxiliary capacitor C3. The Zener diode (Z) may be replaced by one or more ordinary diodes or by a potentiometer the intermediate connection of which is situated between a diode or several diodes and another resistor. The detector can be used at the input of a data processing unit such as a computer.

Filed: 1969-12-17
Abstract: 1285749 Water heaters SULZER BROS Ltd '17 Dec 1969 [6 Oct 1969] 61507/69 Heading F4A A water heater has at least one swirl-type muffle burner 6 arranged at the entry of a cooled flue gas duct 4 containing a heating surface 10, 15. The flue gas duct is of square cross-section and is formed from finned cooling tubes 3 welded together and connected to headers 1, 2. A wall 5 is welded into header 1 and the ceramically lined muffles of four burners 6 extend through it. Each burner is fed with fuel gas and/or oil and air through pipes 40 and 41 and at least two coaxial annular ducts impart a swirl to the air entering the muffle so that combustion requires a minimum of air and gives a high flue gas temperature. The sections 10 and 15 of the heating surface are composed of several pipe coils, disposed across the flue, joined to headers 11, 12 and 13, 14 respectively. Water flows through section 10 first, then through section 15 and finally through the cooling pipes 3. The total flow of the heater is heated in cooling pipes 3, only part flowing through sections 10 and 15. In this way the temperature outside the heating surfaces never falls below the dewpoint of the flue gases. To further ensure this some of the water leaving the heater through pipes 32 to be circulated to a heating system which is pressurized is diverted through a shunt 33 to the return line 20 so that the return water is warmed slightly. A thermostat 50 controls a valve 24 so that a rise in temperature at header 12 causes more water to flow through section 10 and a similar system between valve 30 and header 14 may be provided. In modifications one burner only may be provided and also the heating surface may be divided into three sections rather than two.
