Title: Process for producing sulphur trioxide and/or sulphur acid from gases which contain sulphur dioxide by the catalytic oxidation of the sulphur dioxide
Inventor: DRECHSEL HERBERT
IPC: C01B17/765
Filed: 1965-06-29
Abstract: <PICT:1120232/C1/1> A process for the catalytic conversion of SO2-containing gases having an SO2 content of from 8 to 11% by volume to form SO3 and/or sulphuric acid, comprises subjecting the gases to catalytic conversion in the first stage of a two-stage catalytic converter, each stage of which comprises two contact hurdles, to effect a conversion of 70 to 90% by volume of the total SO2 contained in the starting gases, cooling the gases, effecting an intermediate absorption of the SO3 formed in the first converter stage, and contained the cooled gases, heating the gases to the temperature required for conversion in the second converter stage, subjecting the gases to conversion of the first hurdle of the second converter stage, cooling the gases from the first contact hurdle of the second converter stage to the working temperature of the second contact hurdle, subjecting the gases to conversion over the second contact hurdle of the second converter stage, cooling the gases from the second contact hurdle of the second converter stage, and absorbing the SO3 formed in the second conversion stage.  In an embodiment, the gas produced in sulphur combustion chamber 1 of 10% by volume SO2 content passes through 2 into waste heat boiler 3.  The cooled gas is fed through 4 into first contact hurdle 5 of catalytic converter 6 and leaves through 7 before mixing with cold dried air entering chamber 8 through 9.  The gas flows to a heat exchanger 11 through 10 and is cooled with cold air fed from blower 12 through 13.  The air is discharged from 11 through conduit 14 and through 15 into the second contact hurdle 16.  After conversion of 85% the gas passes to heat exchanger 18 and steam generator or water preheater 19 and then through 20 to absorber 21.  The SO3-freed gases leave 21 through conduit 22, are heated in heat exchanger 18 and pass to third contact hurdle 24 by way of conduit 23.  The gases then enter heat exchanger 26 through conduit 25 and are cooled with cold air supplied through conduit 27 and discharged through 28.  The cooled gases pass through 29 to the last contact hurdle.  The completely catalysed gases leave through 31 to steam generator or feed water preheater 32 before passing by way of 33 to final absorber 34 before discharge through 35. The feed water preheater 19 and/or 32 may be associated with waste heat boiler 3.  Cold air from conduit 14 is combined with that from conduit 28 and flows through 36 to combustion chamber 1.

Title: Direct-viewing half-tone storage device
IPC: H01J31/18
Filed: 1955-09-28
Abstract: 780,907. Storage tubes. HUGHES AIRCRAFT CO. Sept. 28, 1955 [Sept. 30, 1954], No. 27667/55. Class 39(1). A direct-viewing half tone storage tube comprises a mesh screen with a layer of secondary emissive material forming the storage surface upon which is impressed a charge pattern converted by flood electrons into a pattern of predetermined potentials, and a screen substantially in the same plane as the storage surface is pulsed regularly to neutralize the electrostatic field of the charges and permit the flood electrons to penetrate the mesh and impinge on the viewing screen. The tube comprises an electron gun 30 and horizontal and vertical deflection plates 32, 34 for laying down information on a perforated storage screen 26 and a flood gun 36 with collimating lens 52, 54, 56 for directing a broad beam of electrons onto the screen 26. The end wall 23 of the tube supports a viewing screen comprising a transparent conductive coating 68 and a phosphor coating 70. Spaced therefrom is the screen 26 supported by a ring 74 and comprising an electroformed nickel screen 76 bearing a thin layer 78 of secondary emissive dielectric material, e.g. magnesium fluoride, which does not overhang any of the interstices of the nickel screen. A conductive mesh screen 80 is disposed in contact with the dielectric but with its mesh lines at an angle to those of the supporting mesh 76 to eliminate moirÚ. By forming the storage layer 90 as shown in Fig. 3, and exposing parts of the nickel screen 76, the neutralizing screen 80 may be dispensed with. The screen 76 is connected to earth via battery 84 giving it a potential of about 30 volts positive, and the screen 80 is made 0-10 volts positive relative to screen 76 by means of a variable potential source 86. A collector grid 28 stretched across electrode 56 is spaced from the storage screen assembly. The modulated beam from gun 40 lays down a pattern of charge storage on screen 76 and the charge on each elemental area is converted by the flood beam to an upper or lower limiting value according to its original value. The upper and lower values are the potentials of the collector grid. The storage screen 76 is periodically pulsed positive permitting the flood electrons to flow to the viewing screen and be modulated by the charge image to give a half tone replica of the charge pattern. In order to secure progressional erasure of the half tone and full tone charges, the pulses 107 are stepped or triangular or have leading edges, Figs. 7, 8, 9 (not shown).

Filed: 1973-06-11
Abstract: 1393473 Tractor power lift mechanism DEERE & CO 11 June 1973 [12 June 1972] 27723/73 Heading A1P A tractor power system has a selector lever 44 connected to the link 66 for positioning the roller 68 at the D-end of lever 70 for position control in response to the cam on rock shaft 14, or at the L-end of lever 70 for draught control in response to signals from the transverse bendable rod 24. Control means 34 comprises "lower" valve 46 and "raise" valve 48 operated by lever 50 pivoted at 52. "Raise and Lower" hand lever 40 is pivoted at 56 and has an offset pivot 58 which moves a second upright lever 60 for control of valves 46 and 48. If draught control is selected on lever 44 and hand lever 40 is at required operating depth, rod 24, which responds to tension and compression in lower draught links (28) Fig. 1 (not shown), will signal raise or lower to maintain draught. If, however, draught control is selected and hand lever 40 is moved to the raise position for transport rod 24 will signal "lower" and lever 74 pivots about point 76 to move the L-end of lever 70 to the lower position. To stop the implement lowering, link 66 with attached riveted stop 88 (details Fig. 3 not shown), is prevented from following lever 70 by the stop 88 abutting the adjustable stop 90 secured to the housing 12. Stop 90 has an outer eccentric portion 100 and transverse element 102 in tubular carrier 104 with seal 110. The spring 116 creates friction for maintaining the angular setting of stop 90 which determines the position at which the link stop 88 will engage the eccentric portion 100. Stops 88 and 100 will be spaced sufficiently apart to accommodate normal movement of link 66 for draught control.

Title: Improvements in or relating to means for controlling the lateral positions of movingwebs of material
IPC: B41F13/02
Filed: 1955-09-29
Abstract: 786,120. Photo-electric web control. SIEMENS - SCHUCKERTWERKE AKT. - GES. Sept. 29, 1955 [Sept. 29, 1954], No. 27789/55. Class 40 (3). To derive a signal representative of the lateral deviation of a moving web, a mark on a rotating member is arranged to be obscured to an extent dependent on the web deviation so that a photo-electric device scanning the mark produces a signal representative of the deviation. In the arrangement of Fig. 1 a roller 6 driven by the web on a separate constant speed drive carries a sloping mark 4 and rotates in the direction of the arrow. An optical scanning device projects a spot of light on to the other and produces an electrical impulse when the sloping line enters the light beam. The instant of commencement of this impulse depends on the degree of overlap of the sloping line by the edge of the web. A reference pulse is produced by a separate mark 6 which may be on the same roller or a separate member coupled to the roller. The reference pulse may also be derived magnetically. Comparison of the two impulses produces a signal which permits adjustment of the edge of the web. In the arrangement of Fig. 2 a mark parallel to the web axis is carried on a roller whose axis is parallel to the length of the web. Again the instant of occurrence of the output pulse indicates the lateral web position. In the arrangement of Fig. 3, marks 11a, 11b, 11c are carried on roller 2, the arrangement being that the number of such marks completely covered depends on the web position. Thus the frequency of the scanner output pulses indicate the web position. In a still further arrangement the roller may carry triangular marks having their base parallel to the web travel. According to the overlap of the web on these triangles the lengths of the output pulses differ.
