Title: Process for treating gases containing sulphur dioxide from roasting furnaces to render innocuous combustible contact poisons, such as arsine
IPC: C01B17/56
Filed: 1929-12-06
Abstract: Sulphur-dioxide-containing gases, obtained by roasting sulphur-containing ores such as zinc blende, are freed from combustible impurities, such as arsine, by passing them through a second roasting furnace in which the impurities are oxidized to products such as arsenic trioxide, which can be readily removed, for instance, by sulphuric acid washing or by a high tension electrostatic field.  For example, zinc blende containing 25 to 30 per cent sulphur is first roasted in an ordinary furnace, e.g. a Spirlet furnace, at a temperature of about 800 DEG  C. until the sulphur content is about 8 per cent.  It is then completely desulphurized in a Dwight-Lloyd apparatus and the arsine-containing gases from this are taken to the first furnace where the arsine is burnt to arsenic trioxide at the high temperature prevailing therein. The gases are then fit for use in the sulphuric acid contact process.ALSO:Sulphur-dioxide-containing gases, obtained by roasting sulphur-containing ores such as zinc blende, are freed from combustible impurities, such as arsine, by passing them through a second roasting furnace in which the impurities are oxidized to products such as arsenic trioxide, which can be readily removed, for instance, by sulphuric acid washing or by a high-tension electro-static field.

Filed: 1962-10-04
Abstract: 1,012,346. Counting-apparatus. VEEDER ROOT Inc. Oct. 4, 1962 [Oct. 4, 1961], No. 37508/62. Heading G4D. A counter-resetting mechanism, especially for use in liquid-dispensing apparatus, comprises means rotatable in only one direction alternately for resetting and registering. Cost and volume counters 26, 27 and 28, 29 are visible from opposite sides of the dispensing unit. Before he can operate the pump motor switch the operator must turn a handle 91, Fig. 1, counterclockwise whereby a lever 80, Fig. 2, disengages a pawl 74, which is then moved by spring 77 to engage ratchet-wheel 53. Full-stroke mechanism prevents relatching of lever 80 until a control member 54 and reset shaft 43 have made a complete revolution. At the same time a lever 102 switches on a reset motor (not shown) which drives through freely mounted gear 52, ratchet-wheel 53 and pawl 74 the control member 54, shaft 43 and gear segment 50. After a quarter turn gear segment 50 engages gear 48, Fig. 4, and disengages a locking segment 51 from a notch 59 (Fig. 6, not shown). After a further half turn the segment 51 engages another notch 59 and the gear 48 is disengaged. During this time cam 42, Fig. 5, slides plate 37 whereby gear segments 32 displace the counter shafts 22-25 axially to engage the counter drive wheels with resetting gears 44, 45, and resetting takes place in known manner. After resetting the parts return to allow normal drive to the counters and dispensing. At the end of the dispensing operation the operator returns handle 91 so preventing further operation of the pump motor. Specification 776,014 is referred to.

Reversal of a D.C. motor is prevented until it has at least nearly come to rest from its first direction of rotation by an arrangement of relay contacts 30, 31 in series with the energizing coils 11, 14 of direction contactors, the relay contacts being held open by means responsive to the residual voltage generated while the motor continues to rotate. The motor is a series machine whose field 4 is across the diagonal of a bridge arrangement of contacts 9, 10 and 12, 13 of forward and reverse contactors 11, 14. When direction is selected at switch 26 the appropriate contactor 11 or 14 is energized but also a relay 28 or 29 in the opposite contactor circuit is energized through 26 and opens interlock contact 30 or 31. If switch 26 is changed over the relay is held energized by the conduction of a transistor 37 which receives pulses from a pulse former 45 so long as the output of an amplifier 18 is above a threshold value. The amplifier 18 amplifies the A.C. component (ripple) of the voltage produced while the armature rotates.
