Abstract: ABSTRACT OF THE DISCLOSURE Hydrogen sulphide is removed from gas streams in rapid and efficient manner by oxidation to sulphur. The process is effected by intimately contacting the hydrogen sulphide in the gas stream with oxygen in an aqueous medium containing a hydrogen sulphide oxidizing catalyst to effect oxidation of the hydrogen sulphide to sulphur, and transporting the sulphur particles to the  surface  of  the  aqueous  medium.   The  sulphur particles collect on the surface of the aqueous medium and  may   be   removed   therefrom   continuously   or intermittently.

Abstract: TRIGGER CIRCUIT FOR SOLID STATE SWITCH            ABSTRACT:     The power dissipated, in a trigger circuit for gating on a semiconductor switch,  is minimized  by employing  a  constant  current  source  (38,39,45)  to provide the gate trigger current.  This assures adequate triggering regardless of supply voltage variations or switch intrinsic control voltage requirements.  Power is saved by supplying only the current required to drive the semiconductor switch on,  thereby preventing over-drive.  With constant d-c gate current, the precise amount of power needed to turn on and close the switch is provided while wasting relatively little energy due to gate intrinsic voltage variations of the switch or to input line voltage variations.

Abstract: TEST CONTACT RESISTANCE OF DRY CIRCUIT CONTACTS          Abstract of the Disclosure In the testing of dry circuit contacts, a constant current source is applied to the contacts.  The open circuit voltage of the source is set to a predetermined maximum value and then the short circuit current at the contacts measured.  If the current value is below a predetermined maximum value, the voltage of the source is increased to bring the short-circuit current to the predetermined value.  The voltage drop across the contacts is then measured and the contact resistance calculated.  This arrangement makes adjustments to take into account variations in the test circuit, such as different lead lengths and other variables, without subjecting the contacts at any time to an open circuit voltage or short circuit current above maximum values.       - i -

Abstract: ABSTRACT      A cyclic shear energy absorber is described for absorbing energy imposed onto the absorber.  The absorber consists of a hollow core filled with densely packed granular material.  The granular material is confined within the core so that cyclic shear energy imposed upon the absorber causes incipient dilation of the granular material.  This incipient dilation is at least in part suppressed by the confining means.  Inter-particle frictional forces within the granular material dissipate the imposed cyclic shear energy.  The absorber may be confined between two end plates capable of being coupled to an associated structure such as a bridge support column and a base.  The core may also be confined within a pile.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for the production of pig iron from iron ore is disclosed.  The pig iron is firstly converted to sponge iron in a direct reduction shaft furnace and then the sponge iron is converted to pig iron in a melt-down gasifier.  The shaft furnace and melt-down gasifier are interconnected by means of downcomers.          Apart from the sponge iron, the melt-down gasifier is supplied with a carbon carrier in the form of coke and oxygen-containing gas.  The gas produced in the melt-down gasifier is supplied to the shaft furnace in the form of reduction gas via downcomers, pipe, cyclone separator and pipe.  By means of pipes, cooled, cleaned blast furnace gas form shaft furnace is admixed as cool-ing gas with the gas produced in the melt-down gasifier.  With the aid of a screen, the melt-down gasifier is supplied with the fine fraction via pipe and the shaft furnace is supplied via pipe with the coarse fraction of the coke required for the operation of the plant.  The coke introduced into the shaft furnace passes through the same and then enters the melt-down gasifier in pre-heated, dried form.  The coke in the shaft furnace also leads to a reduction of Co2 and H2O to CO and H2 and also reduces the sticking tendency of the sponge iron.
