Title: Improvements in or relating to control devices for liquid and gaseous fuel burners
IPC: F23N5/24
Filed: 1960-04-22
Abstract: 906,162. Photo-electric burner control. NORMACEM. April 22, 1960 [May 28, 1959], No. 14320/60. Class 40 (3). In a system for controlling oil and gaseous fuel burners by means of an operating relay controlled by a variable-resistance photo-electric cell illuminated by the burner, a safety arrangement is provided by supplying two separate electric currents to the photo-cell, one of which serves for the normal energization of the relay and the other for the detection of any shortcircuit affecting the cell or its connections, the detecting current normally assuming a relatively small value and being substantially increased on the occurrence of such a short-circuit so that it becomes capable of operating means to effect a safety control operation. The normal operating current in for the coil L of the control relay and variable-resistance photo-cell P is derived from A.C. U1 terminals fed from B, A, through a half-wave rectifier R1. A detecting current id normally of small value relative to in is derived from A.C. U2 at terminals B,C and fed through a half-wave rectifier R2 and the photo-cell P. A safety fuse f is included in the conductor from the terminal B, and in normal operation the flame illuminates the cell P so that the control relay is operated, and the failure of the burner effects the release of the control relay to cut off the supply of fuel. On the occurrence of a short-circuit between the points S1 and S2, the currents in, id are increased, but the latter to considerably greater extent and blows the fuse f so that the current supply to the coil L is cut off and the control relay is released to effect discontinuance of the fuel supply, e.g. by closing a valve or stopping a motor. In an alternative arrangement, Fig. 3 (not shown), the normal operating current for the coil of the control relay and for the photo-cell is derived from a rectifier bridge connected to an A.C. supply and the normally small detecting current is obtained from separate A.C. terminals with a capacitor in series with the photo-electric cell. The safetyfuse is located in the output of the rectifier bridge and also in the supply circuit from the separate A.C. terminals, and the arrangement is such that when the fuse is blown the control relay is released although its coil carries a small amount from a subsidiary circuit to the separate A.C. supply.

Title: Purifying sulphur compound contaminated gas streams
IPC: B01D53/50
Filed: 1973-03-26
Abstract: 1424064 Desulphurising gases W R GRACE & CO 26 March 1973 [30 March 1972] 14363/ 73 Heading B1L [Also in Division C1] Sour gases are desulphurised by adsorption in two beds, e.g. containing a zeolite or molecular sieve with simultaneous desorption from two further beds, each of the four beds being at a different stage of a four stage cycle and being cyclically switched between adsorption and desorption duties. In the first and second stages contaminants are adsorbed at high pressure, in the third stage the contaminants are partially removed by depressurisation and oxidised to elemental S by passage of an oxygen containing gas, the S being recovered from the oxygen depleted gas exiting the bed and in the fourth stage residual contaminants are vaporised and removed from the bed by passage of a gas at at least 440C, followed by passage of a cooling gas and recycling the bed to the first stage. Also effluent from each third stage bed is passed through an auxiliary bed where the resulting adsorbed contaminants are oxidised to sulphur by oxygen containing gases and effluent from each fourth stage bed passes through a second auxiliary bed to free it or residual contaminants and cool it. The auxiliary beds alternate between adsorption and regeneration duty. In the apparatus of Figure 1 contaminants from sour gas from source 7 are adsorbed or molecular sieves in bed 1 until this bed is approximately half saturated with contaminants. Purified gas from beds 1 and 4 is stored, used in the process or flows to a distribution point. During this stage bed 4 is on a second adsorbing step and is fully loaded with contaminants and bed 3 (which was fully loaded with contaminants in the previous step 8 sequence) is depressurised and reacted with oxygen containing gas. During depressurisation bed 3 is connected to auxiliary bed 5 which adsorbs contaminants overflowing from bed 3, purified effluent passing to flare vent 59. Then adsorbed contaminants in beds 3 and 5 are oxidised to sulphur by air from source 13 and reservoir 33 and the liquid sulphur is removed is condenser-container 52. At the same time beds 2 and 6 are regenerated by passage of a gas of low free O 2  content from reservoir 33 and heater 32 at at least 440C to vaporise elementary sulphur and remove it to condenser 52. The remaining gas is returned to reservoir 33 and beds 2 and 6 are cooled to below 120C by passage of gas from source 13. Residual gas passes to reservoir 33. Finally beds 2 and 6 are purged of air using purified gas which escapes through flare vent 59. In the second, third and fourth stages each of the beds undergoes different steps.
