Abstract: 1411626 Sulphur dioxide BAYER AG 28 Nov 1972 [2 Dec 1971] 54970/72 Heading C1A Sulphur dioxide is produced by burning in a first combustion stage 5-40% by weight of the total sulphur to be reacted at a temperature of between 1700 C. and 2000 C. in the absence of external cooling with at most the stoichiometric quantity of molecular oxygen in the presence of 1 to 2 times its molar amount of recycled SO 2  at 50-100 C., cooling the combustion gases and mixing them in a second combustion stage with the remainder of the sulphur and the necessary quantity of oxygen and burning at 1700- 2500 C. and finally cooling the sulphur dioxide product. Part of the cooled SO 2  may be recycled prior to condensation to the first combustion stage. The second combustion stage may comprise two to four steps, the gases leaving each step being cooled to 800-1000 C. before entry into the subsequent step. Sulphur and oxygen are added to the individual steps of the second combustion stage in stoichiometric quantities such that the heat flow in the individual stages does not exceed 10<SP>6</SP> Kcal./m.<SP>2</SP>h. The sulphur dioxide formed may be converted into sulphur trioxide by the contact process.

Title: Process and apparatus for the utilization of low heat value gaseous fuels
Inventor: KIVLEN JOHN ANTHONY
IPC: F23G7/06
Filed: 1967-12-04
Abstract: 1,206,455. Burning waste gases. ESSO RESEARCH & ENG. CO. 4 Dec., 1967, No. 55076/67. Heading F4B. A process for the combustion of low heating value gaseous fuels (i.e. fuels with a heating value <10,000 BTu/lb), which contain from about 5-15 volume per cent carbon monoxide and from about 80-95 volume per cent inert gases, is characterized by sequentially burning a high heating value fuel (>10,000 BTu/lb.) to produce hot combustion gases, mixing the hot combustion gases with a portion of the low heating value fuel and burning the CO in the low heating value fuel in a first stage, mixing the hot combustion gases from the first stage with the remainder of the low heating value fuel and burning the CO in the low heating value fuel in a second stage. A furnace for the above process comprises a horizontal combustion chamber 11, a vertical heat transfer zone 13 and a transition zone 12, said combustion zone 11 having a plurality of low heat value fuel supply means 4, 5 spaced apart along the zone defining combustion chambers 6, 7, and burner means 9 positioned in the end of said zone 11 to supply hot combustion gases from the combustion of high heat value fuel to the combustion zone. As shown, regenerator off gas at a temperature of 400-1100‹ F. is passed into distribution ducts 7, 6 defining first and second stage combustion areas. The burner 9, fed with high heat value fuel and with sufficient excess air from line 10 for the first stage of CO combustion, provides heat output sufficient to heat the first stage combustion areas to 1100-1400‹ F., thus burning the carbon monoxide completely. The hot combustion gases from the first stage pass to the second stage, where the other portion of the relatively cold CO containing gas is introduced into the combustion zone along with combustion air from line 32, the high temperature gas mass being used to heat the gas to ignition temperature. The combustion gases, now generally at 1600-2200‹ F. pass through the transition zone to be used for generating steam and for heating the feed to a catalytic cracking unit.

A release device for loads clamped on an endless conveyer comprises a release member which is shifted between operative and retracted positions by connections transmitting drive from an intermittently running rotary electric motor. As shown the operating arm 60 of a bag gripper 61 is engaged by a centrally articulated gripper-opening cam 54 when moved to its operating position upon actuation of an electric motor 43 driving a circular crank 46 through a gearbox 45. Connection between the crank 46 and the cam 54 is by a close-coiled tension spring link 48 to allow the cam 54 to straighten on encountering a seized bag gripper. Release of the gripper 61 is initiated at a particular unloading station (not shown) by correspondence between a code on a code peg carried by the bag gripper and a code switch, Fig. 4 (not shown), at the station, unless a photo-electric cell (not shown) at the station indicates the absence of a bag. The gear-box 45 drives the crank 46 half a revolution to operate the cam 54 and, on operation of a retract switch, a further half revolution to return the cam 54 to its retracted position unless the signal is cancelled by the succeeding bag carrier carrying a code also requiring its bag to be unloaded at the same station.

Abstract: 1,212,527. Lung ventilators. F. M. BIRD and H. L. POHNDORF. 7 Dec., 1967 [14 Dec., 1966], No. 55618/67. Heading A5T. A lung ventilating assembly in which the expiratory and inspiratory times are each con trolled by a metering valve 52 supplying fluid to a fluid-operated means (e.g. a diaphragm 33) controlling a flow control valve 32, one of the valves being a gas supply valve which when opened by one fluid operated means permits supply of respiratory gas and the other flow control valve 32 being a vent valve opened by the other fluid operated means to vent the first metering valve and cause closure of the gas supply valve and opening of a vent valve 74 associated with the second metering valve resulting in closure of the other valve, both flow control valves being in closed position during the expiratory phase and open position during a portion of the inspiratory phase. The device comprises an expiratory cartridge 17, and an inspiratory cartridge 16, each of the cartridges comprising a flow control valve 32 which is opened against a spring 37 in response to fluid pressure on a diaphragm 33. For opening each valve pressure is built up in a diaphragm control chamber 36 through an adjustable needle valve 52. A gas source is connected through a cock 26 and inlet fittings 23 including a filter 20 to nipples 67, 68 of the expiratory cartridge. At the end of the inspiratory phase the valves 32 of both cartridges are closed so that gas supply to a flow pressure control assembly 18 and an outlet fitting 24 is cut off. Gas supplied to the nipple 68 flows through the needle valve 52 of the expiratory cartridge, which is adjustable to determine the expiratory time, to the diaphragm chamber 36 of the expiratory cartridge where pressure builds until the valve 32 of the expiratory cartridge opens to terminate the expiratory phase. Gas them flows via valve 32 of the expiratory cartridge to the outlet fitting 24 and also through the needle valve 52 of the inspiratory cartridge to the diaphragm chamber 36 of the inspiratory cartridge and to a diaphragm chamber 87 to close the vent valve 74. Pressure builds up in the chamber 36 of the inspiratory cartridge so that at the end of the inspiratory time, as determined by the needle valve 52 of the inspiratory cartridge, valve 32 of the inspiratory cartridge is opened to vent the needle valve 52 of the expiratory cartridge through a nipple 71 and cause closure of the valve 32 of the expiratory cartridge. The vent valve 74 then opens to vent the diaphragm chamber 36 of the inspiratory cartridge, the assembly 18 and apparatus connected to. the outlet fitting 24.
