Title: Improvements in manufacture of sulphur dioxide
IPC: C01B17/52
Filed: 1934-07-30
Abstract: Sulphur dioxide; iron oxides; furnaces.--In obtaining sulphur dioxide by oxidizing fine particles of iron pyrites in suspension in a roaster having a throat opening into the combustion zone, the material is shaken through a screen in the form of a shower of fine particles into the throat separately from the air for oxidizing, and by applying suction to a remote portion of the combustion zone the air for oxidizing is induced to flow into the combustion zone in two independently regulatable streams, one entering the throat and mixing uniformly with the shower of pyrites and the other entering in annular form about the throat, uniformly surrounding and combining with the shower of pyrites. As shown in Fig. 2, finely divided pyrites is fed from a conveyer 6 on to a power operated vibrating screen 12 which shakes the material through a screen 13 into a feeding funnel 14.  One stream of air for combustion is drawn through regulatable openings 16 into the funnel and the other through regulatable openings 17 about the <PICT:0442437/III/1> <PICT:0442437/III/2> funnel by means of a fan connected to the gas outlet 10.  The combustion may be initiated by a burner ring 22.  The walls of the combustion chamber are corrugated as shown at 24 and are surrounded by a water jacket 25 to provide cooling.  The oxides collect at the bottom of the roaster in a dry seal formed between the conical bottom of the furnace and the conical bottom 28 of a water space 34.  The annular top of the water space is covered by a cap 37 which has a conical top, and sides which extend downwardly over the water jacket to form an annular channel 39. The gases travel to the bottom of the furnace, make a sharp turn into the channel 39, and pass out of the roaster through a central channel 31 and the lateral outlet 10.  Oxides deposited in the channel 31 pass through a contracted opening 32 into the dry seal. The water space 34 communicates with the water jacket 25 by means of pipes 35 and 36. The magnetic oxides still remaining in suspension in the gas are separated by cooling followed by magnetic separation.  The gas conduit may be forked, a magnetic separator being interposed in each fork so that one may be cleared while the other is in use.  The sulphur trioxide content of the gas may be kept at a minimum by a speedy flow of the gases through the critical temperature zone. Magnetic separators.--Each magnetic separator employed as above may comprise of alternately arranged overlapping magnetizable plates 42, 43, Fig. 4, extending respectively downwardly from the roof and upwardly from the floor and downwardly opening hinged discharge doors 44.

Title: Fluid flow control valves
IPC: F15B13/04
Filed: 1953-08-14
Abstract: 731,332. Valves. JOHNSON, C. Aug. 14, 1953 [April 15, 1953], No. 22446/53. Class 135. A valve suitable for controlling a double-acting piston and cylinder motor and actuated either directly by a hand lever or under the control of a pilot ball-valve which may be operated by a hand lever or by a solenoid comprises a valve member 20 with lands 58, 60, 62 flanked by resilient sealing rings 66 of round cross-section and slidable in spaced liner elements 24, 26, 28, 30. The outer sealing ring 66 of the lands 58, 62 may be omitted. The liner elements, which carry external sealing rings 42, 44, are spaced apart by cylindrical filters 34 to provide ports 36, 40 which communicate through adjustable valves 130, 128, with an exhaust manifold 16, and a port 38 connecting with a pressure fluid inlet 108. Radial ports 52, 54 in the liner elements 26, 28 connect through cylindrical filters 48 with the two ends of the motor to be controlled. The valves 128, 130, control the rate of exhausting from each end of the motor so that the speed of the latter in either direction may be determined independently. In the form shown the valve is controlled by a pilot valve comprising a ball 98 movable between opposed seats 94, 96 consisting of resilient sealing rings. An arm 158, flexibly mounted at its upper end and carrying a pin 156 to engage the ball 98, is normally urged by a spring 178 to hold the ball against the seat 94 so that a chamber 74, in which a piston 72 integral with the valve number 20 is slidable, is vented through passages 106, 104. This permits pressure fluid admitted through a filter 112 and passages 14, 114 to a piston 68 integral with the valve member to move the latter to the right. Pressure fluid from the passage 114 acting on the liner element 24 also constantly urges the liner elements to the right to ensure that the sealing ring 44 performs its function. When the solenoid 180 is energized it withdraws the arm 158 so that the ball 98 is urged to the seat 96 by pressure in the passage 14 which then has access to the chamber 74 to move the valve member to the left owing to the greater area of the piston 72 than that of the piston 68. Hardened steel inserts 77 at the ends of the valve member coact with similar, fixed inserts 79. In a modification the arm 158 is rocked by a hand lever instead of by the solenoid. The unit carrying the pilot valve may be mounted remote from the main valve. In another modification a solenoid operated pilot valve may be mounted at each end of the main valve to control the associated piston. In this case the pistons may be of the same or of differing area. In a further embodiment the valve member 20 is connected directly to a hand lever and is located in its two end positions and also in an intermediate position by a spring-pressed ball engaging grooves.
